"Exercise reduces the symptoms of attention-deficit/hyperactivity disorder and improves social behaviour, motor skills, strength and neuropsychological parameters". Acta Paediatr. 103 (7): 709–14. doi:10.1111/apa.12628. PMID 24612421. The present review summarises the impact of exercise interventions (1–10 weeks in duration with at least two sessions each week) on parameters related to ADHD in 7-to 13-year-old children. We may conclude that all different types of exercise (here yoga, active games with and without the involvement of balls, walking and athletic training) attenuate the characteristic symptoms of ADHD and improve social behaviour, motor skills, strength and neuropsychological parameters without any undesirable side effects. Available reports do not reveal which type, intensity, duration and frequency of exercise is most effective in this respect and future research focusing on this question with randomised and controlled long-term interventions is warranted.

One almost overall finding, at least in endurance and strengthendurance athletes having OTS, is a diminished maximal lactate concentration, whereas submaximal values remain unchanged or slightly reduced.10 12 This is confirmed in the present study where OTS patients did not reach maximal lactate concentrations above 8 mmol l−1. Two out of the four NFO patients did not reach [La]max of 8 mmol l−1 at the first exercise test either (for one patient [La]max was missing). Thus, although low [La]max has frequently been described as a diagnostic marker for OTS, from these results, it does not seem sensitive enough to distinguish OTS from NFO.
Both groups performed an equal proportion of exercise sessions alone (MCT: 50%, HIIT: 49.6%) and together with others (MCT: 50%, HIIT: 50.4%). In both groups, women had a significantly higher proportion of sessions together with others compared to men (56% vs. 44%, p < 0.01). The HIIT group had a significantly higher proportion of sessions organized by Generation 100 compared to the MCT group (8.1% vs. 5.9%, p < 0.01).

Stuck in the strength training doldrums? Our best piece of fitness advice is that "Variety is key." Greatist has shared all sorts of ways to take workouts from "hum drum" to "hot stuff." We're now turning our eye to eight effective strength training techniques. So grab that workout log and a pen, because here are some great ways to challenge the status quo and add a little variety to the normal gym routine.
Length of the Workout – How long is the workout on the video you are looking to get? If you want to work out 30 minutes a day, getting an exercise video that is 60 minutes long will only cause frustration. Most people don’t want to do half a workout and since they are designed to include a warm up, workout and cool down, only watching half gives you an incomplete workout.

Too much exercise can be harmful. Without proper rest, the chance of stroke or other circulation problems increases,[80] and muscle tissue may develop slowly. Extremely intense, long-term cardiovascular exercise, as can be seen in athletes who train for multiple marathons, has been associated with scarring of the heart and heart rhythm abnormalities.[81][82][83] Specifically, high cardiac output has been shown to cause enlargement of the left and right ventricle volumes, increased ventricle wall thickness, and greater cardiac mass. These changes further result in myocardial cell damage in the lining of the heart, leading to scar tissue and thickened walls. During these processes, the protein troponin increases in the bloodstream, indicating cardiac muscle cell death and increased stress on the heart itself.[84]

Strength training means using resistance to work your muscles; that can be your bodyweight, dumbbells, kettlebells, sand bags, resistance bands, etc. The goal of this type of workout is to increase muscle mass. Getting stronger helps improve everyday performance (from sports to regular life), prevent injuries, and increase your metabolism. Need a primer on where to start? We’ve got you covered.
One of the rotator cuff strengthening exercises proposed by Kuhn is scaption performed with the thumb down or up. Clinically, this exercise is called the empty-can (thumb-down) or full-can (thumb-up) exercise. When prescribing this strengthening exercise, one should consider the effect that upper extremity position has on the tissues located in the subacromial space. Yanai et al4 showed that impingement forces on the rotator cuff tendons under the coracoacromial ligament were greater with the empty-can exercise than with the full-can exercise. Therefore, the full-can exercise is more appropriate for this patient population.
There are many things a consumer can do to minimize unsatisfactory purchases when it comes to exercise videos. We have put together a buyer’s guide that will give you a lot of information on learning as much as you can about exercise videos and what they are about BEFORE you spend the money. When you are armed with this information you can be more assured that the videos you decide to purchase will actually be ones you use.

Building Strength. Alan Calvert, the Milo bar-bell company, and the modernization of American weight training; PhD thesis. Austin: The University of Texas; 2006. [Google Scholar] This forced both traditional Physical Culture systems to require new professional establishments. Competitive athletes and gymnasts started training under ‘The International Gymnastics Federation’ (established in 1881)13 International Gymnastic Federation (FIG) [Internet].

Between 1890 and 1925, at least six new MMB schools emerged, sharing a similar exercise philosophy and practicing similar exercises. These methods, which are the focus of this paper, were led by six charismatic pioneers: Checkley, Müller, Alexander, Randell, Pilates, and Morris.
Take the stairs. You know, some people pay to use stairs (read: they buy a stair stepper machine), so if you work or live above the first floor, consider using your stairs as a privilege. Using the stairs is great cardiovascular exercise, and also tones your calves, hamstrings, glutes, quadriceps, and abs. Next time you're about to take the elevator or escalator, take the stairs instead. If you have some time to spare, take an extra trip up and down. Or, try a stair-based workout like this one.

Exercise was defined as planned, structured activities, for instance going for walks, skiing, swimming and doing sports, but also as unplanned activities that the participants experienced as exercise. The participants were asked to fill in exercise logs immediately after each exercise session they performed throughout the year and send them to the research center either in prepaid envelopes monthly, or to use internet-based forms following each exercise session [21]. Exercise frequency was calculated as the mean number of sessions reported per week during the year. To assess intensity of exercise the participants reported their subjective RPE on a Borg scale ranging from 6 to 20 [20]. The participants were asked to report the mean intensity level during the exercise session. Ratings from 6 to 10 were classified as low intensity, 11 to 14 as moderate intensity, and 15 to 20 as high intensity. Duration of exercise was measured with a 4-point scale: less than 15 min, 15–29 min, 30 min to 1 h, and more than 1 h. Less than 15 min and 15–29 min was combined due to a low response rate on these response options (1.1 and 8.7% of the total number of exercise sessions, respectively).
Stand on right foot with left foot elevated and core tight. Hop 3 times then bend down and quickly walk hands out so you are in a high plank position with left foot still off ground. Do 3 push-ups, never putting left foot down. Walk hands back and stand up to return to starting position. Repeat for half the time on one side only, then switch sides.
Pilates and his followers stood apart from the other MMB schools for surviving a turbulent century, for making multiple millions of people healthier in mind and body and for being a major force in reintroducing mind–body methods to healthcare establishments today. Furthermore, Pilates deserves credit for inventing his ingenious exercise equipment, which uniquely blends in harmoniously with the universal mind–body philosophy.

Tracy Anderson: The Method For Beginners. Choose from a handful of workout DVDs from this celebrity trainer. She’ll have you working up a sweat doing cardio or more targeted moves for the arms, legs, and core. Anderson’s queue of videos range from about $2.99 to $9.99. Considering that Anderson has her own collection of studios across the globe that run about $45 per class, this is a steal!

Budget IS Important, But… – It’s always a good idea to have a budget in mind when it comes to buying anything, but don’t look for the cheapest exercise videos on the market. The adage you get what you pay for is definitely true. That doesn’t mean to spend way over your budget either. The point of this particular tip is that you should look for good quality videos and keep your budget in mind as well. Not all inexpensive videos are bad of course, but buying simply from a price point can quickly add up to nothing but a collection of dusty, unused exercise videos on your shelf.
Choose clothes that suit your activity. In general, wear clothes that won’t restrict your movement or blood flow. For some forms of exercise, like biking, you might want to wear form-fitting clothes, but they still shouldn’t be too tight. Looser workout clothes are better for strength training, brisk walking, and sports such as basketball or soccer.[35]
Improving your balance makes you feel steadier on your feet and helps prevent falls. It's especially important as we get older, when the systems that help us maintain balance—our vision, our inner ear, and our leg muscles and joints—tend to break down. "The good news is that training your balance can help prevent and reverse these losses," says Wilson.
An early detailed documentation of a Western mind–body exercise philosophy was created in the late 18th century by Swedish medical gymnastics teacher Pehr Henrik Ling (1766–1839), who is remembered as the father of Swedish Gymnastics. Ling developed an apparatus-free method to improve functional movement and concurrently address the concept of prevention and healing of human diseases.4 Bakewell S. Illustrations from the Wellcome Institute Library: Medical gymnastics and the Cyriax collection. Med Hist. 1997;41:487–95.10.1017/S0025727300063067[Crossref], [PubMed], [Web of Science ®] [Google Scholar] His early age rheumatism, experiences as a Fencing Master and his studies of medicine at Uppsala University influenced his ideas on the remedial benefits of physical training.5 Brodin H. Per Henrik Ling and his impact on gymnastics. Sven Med Tidskr. 2008;12(1):61–8.[PubMed] [Google Scholar] His 1853 book ‘Gymnastic Free Exercises’ stated: ‘It cannot be denied that the art of preventing disease is far preferable to that of curing it.’6 Ling PH. The gymnastic free exercises. Boston (MA): Ticknor, Reed and Fields; 1853. [Google Scholar] Ling regarded his ‘gymnastic free exercises’ as one of two separate yet related systems; the other being competitive gymnastics and athletics. Together, these two systems defined what became the Physical Culture or Gymnasium Movement of the 19th century.5,7 Brodin H. Per Henrik Ling and his impact on gymnastics.

The mental benefits of barre are similar to yoga and Pilates, as it effectively increases mind-body awareness and mental clarity. Focus and concentration are required to perform the small precise movements utilized in barre. Allowing your mind to concentrate solely on your technique increases feelings of relaxation and decreases stress levels. Endorphins released during physical activity increase your general sense of well-being.
This is a lift that builds full-body power and tests the ability to move quickly. HOW TO DO IT: Start with the bar on the ground. Place your hands on the bar -- a little outside of your shins -- with the bar touching your mid shin. You should keep your weight on your heels with your chest big and pull the bar up like a deadlift, while driving the knees back so that the bar path stays perpendicular to the floor and you stay over the bar. This utilizes your hip hinge and activates your posterior chain. Once the bar passes the knees, you jump up (you may not actually leave the ground, but you should feel like you’re trying to) and shrug so that the bar comes as high as possible. The next step is for you to get under the bar or “catch” it as quickly as possible by squatting under the bar and changing the hand position underneath the bar, putting the body into a front squat position with the bar resting on the shoulders. You then stand the bar up. MUSCLES USED: Glutes, quads, hamstring, calves, shoulders, core and traps.
Frequency, intensity, type, location and social setting (alone vs. together with others) of exercise were assessed using exercise logs from 618 older adults (aged 70–77 years) randomized to MCT or HIIT. All participants completed exercise logs after each exercise session they performed during one year. Pearson Chi-square tests were run to assess the association between intensity, type, location and social setting of exercise with training group.
Founder Ken Hutchins' SuperSlow has been 'managed' by unscrupulous business partners, into a commercial entity bearing little resemblance to his original intention, (& no involvement with Mr Hutchins himself, nor any of his original associates). The -real- SS was revolutionary for its time, but Hutchins' new textbook, "The Renaissance of Exercise, a Vitruvian Adventure", is the result of his ongoing refinements over the past 18 years. Rather than pay over a $150 for the supposed historic value of a slim, soft-cover, dog-eared $10 book & it's relatively primitive ideas, get the new hard-cover textbook./It seems that one of the main criticisms os The Manual is "too much information". True, for a casual reader.The fact is, ANY exercise protocol is simple enough to write up on one or two pages: How many sets. How many reps. How many exercises. How often. About 10 exercise technique descriptions: Done. It's the precise whys, hows, & special cases that take a book to fulfill.
Challenge yourself with interval training. Interval training involves alternating high-intensity and low-intensity exercises, and it’s a great way to burn calories. Since it involves high-intensity activities, such as running or sprinting, it's best to include interval training in your routine if you're already used to regular exercise. For a good, basic interval session, try doing a sprint-walk routine.[15]

Behind the seemingly uniform acute hormonal response to exercise, explaining the disturbance to the neuroendocrine system caused by OTS is not that simple. There are several similarities with other intensive and chronic stress situations. There is compelling evidence for the involvement of HPA axis abnormalities in chronic stress situations such as post-traumatic stress disorder17 and depression25 and probably also during NFO and OTS. In chronic stress situations, the number of ACTH and cortisol secretion pulses is increased, which is also reflected in elevated urinary cortisol production.25


2. On Super Slow, you should be using about as much resistance as you use on a traditional strength training workout. A traditional strength training set is 10 repetitions at a speed of 2 seconds up and 2 seconds down per repetition. That's 40 seconds per working set. 2-4 Super Slow repetitions, at 10 seconds up and 10 seconds down, is 40-80 seconds, or at most twice as much time. At that pace, if you could handle 100 pounds at 10 reps of 2/2 you should be able to handle 100 pounds for 3 reps of 10/10.
The first step to any workout routine is to evaluate how fit you are for your chosen physical activity. Whenever you begin an exercise program, it's wise to consult a doctor. Anyone with major health risks, males aged 45 and older, and women aged 55 and older should get medical clearance, says Cedric Bryant, PhD, chief exercise physiologist for the American Council on Exercise.
A compound exercise is a move that incorporates multiple muscle groups, like lunges, deadlifts, and squats. It may also refer to two moves being strung together, like a bicep curl to a shoulder press. Compound exercises are efficient for increasing overall muscle mass and burning calories (because they require more effort to complete), as opposed to isolation exercises, which focus on working just one muscle group (like a bicep curl).
After trying many different workout "schemes" with limited success, I bought this book and began doing Super Slow workouts. I'm now working out 6 times a month, spending less than 30 minutes in the gym for each workout, and I'm stronger than I've ever been. I've never experienced progress like this before. At 45 years old, my leg press has gone from 400 to 820 lbs. in a couple of months. The workouts aren't easy, but they're over quickly, and I'm able to spend more time with my family without feeling like I'm compromisng my health and fitness.
Video Abstract for the ESSR 44.4 article “The Age-Associated Reduction in Propulsive Power Generation in Walking” from author Jason R. Franz. Propulsive power generation during push-off in walking decreases with advancing age. A common explanation is an accommodation for sarcopenia and muscle weakness. Yet, muscle strengthening often yields disappointing outcomes for walking performance. We examine the hypothesis that declines in force or power generating capacity of propulsive leg muscles cannot fully explain the age-related reduction in propulsive power generation during walking.
I saw the commercial for this program a few years ago on TV and laughed when it came on. I thought it was just another one of those infomercials that advertised something unattainable and absolutely ridiculous. Who could possibly get ripped by working out in their living room for an hour a day? Well, let's fast forward 3 years later to 2011 and I certainly wasn't laughing anymore. During my college years I managed to pack on 50 pounds of extra weight that needed to come off. So, I went on a diet and started working out at the local gym. Well, that whole gym thing didn't last long. Between gas prices and the membership cost, I just wasn't feeling it. While venting to one of my friends, he suggested that I do P90x. Needless to say he received an eyebrow raise from me. Fast forward another 2 weeks later ... full review
This stands for rate of perceived exertion, and refers to intensity. It’s a point of reference that trainers often use to communicate how hard you should be working since what feels easy or challenging is different for everyone. On the RPE scale a 1 pretty much means zero effort while a 10 means you’re working harder than you thought you possibly could.
This move requires a great deal of strength, balance and flexibility. HOW TO DO IT: Start by standing on one leg. The opposite leg can be held out in front of your body with your hands on the non-working leg. Think about rooting your foot into the ground while you squat down and back so that the glutes pass below parallel. MUSCLES USED: Glutes, quads, hamstrings and calves.
Planks are a quadruple threat, and by holding one for just 30 seconds a day, you will instantly start seeing results on your abdominal muscles, arms, triceps, and core. Riggins suggests doing low and high planks for 30 seconds each. For the low plank, he says to “get up on your elbows and your feet like a push-up position. You can modify by getting on your knees and hold for 30 seconds.” For the high plank do the same but “hold your legs straight” for 30 seconds.

Try to keep legs still and only move torso.” Keep your focus; and brush up on these 22 Truths About Willpower if you need help making the most of your 30 seconds.
Intensity: The best exercise intensity for CFS/ME patients is low intensity and low-impact, at least in the beginning. IF post exercise malaise occurs, try not to skip workouts, just go back to a lower intensity and less duration. Please note that I do consider cleaning one of those daily activities that can be harder on the fibro body than structured exercise. Do not determine your ability to exercise on difficulty with cleaning, bending, stopping, starting, etc that is involved there.

For this basic strength-training workout, you'll do 1 set of 15 reps of each of the nine exercises listed below, resting briefly between exercises as needed. The workout targets all the muscles in the body, including the chest, shoulders, arms, back, hips, glutes, and thighs. It's short and simple—a great way for beginners to get started with strength training.

Preliminary evidence from a 2012 review indicated that physical training for up to four months may increase sleep quality in adults over 40 years of age.[78] A 2010 review suggested that exercise generally improved sleep for most people, and may help with insomnia, but there is insufficient evidence to draw detailed conclusions about the relationship between exercise and sleep.[79]

The participants completed in total 69 492 exercise logs (33 608 HIIT group) during the year, of which 39 075 were received in prepaid envelopes and 30 417 in internet-based forms. Both groups performed 2.2 ± 1.3 exercise sessions per week. Almost 80% of the sessions in the MCT group were actually performed with moderate intensity (11–14 on the Borg scale), while almost 60% of the sessions in the HIIT group were performed with high intensity (≥15 on the Borg scale) (Fig. 2). In the MCT group, women had a significantly higher proportion of sessions with moderate intensity compared to men (81.7% vs. 74.9%, p < 0.01). In the HIIT group, men had a higher proportion of sessions with high intensity compared to women (63.7% vs. 52.3%, p < 0.01) (Fig. 2). In the MCT group, 9.6, 43 and 47.4% of the sessions had a duration of < 30 min, 30 min to 1 h, and more than 1 h, respectively. The corresponding percentages in the HIIT group were 10.1, 45 and 44.9%.
Another very important brain area that mediates, and in turn is affected by the stress response, is the hippocampus.27 The consequences of impaired regulation of cortisol secretion are manifold, ranging from effects in peripheral tissues (eg, osteoporosis) to changes in the central nervous system.28 Most of the effects seen in chronic stress situations can be explained by the occupation of the two glucocorticoid receptors in the brain. In normal situations, the mineralocorticoid receptor will be occupied, whereas the glucocorticoid receptor has lower affinity for the natural ligand corticosterone (cortisol) than the mineralocorticoid receptor and is extensively activated only after stress and at the peaks of the circadian rhythm. One of the main functions of glucocorticoid receptors is to normalise brain activity some hours after an organism has been exposed to a stressful event and to promote consolidation of the event for future use.25 28 To this purpose, corticosteroids feed back in precisely those circuits that are initially activated by the stressor and are enriched in glucocorticoid receptors: limbic forebrain neurons and the paraventricular nucleus of the hypothalamus.
Stephanie Mansour, weight loss and lifestyle coach for women, has a great way to get your triceps toned while you’re watching TV. Just do 30 tricep dips on your couch. Here’s how: “Hands on edge of couch, fingers facing you. Bend your knees at 90-degree angle, scooting your butt up so it almost touches the couch,” she says. “Bend at the elbows, lower your body down, then press back up and straighten your arms. Repeat for 30 seconds to work on arm flab.”

There is also some evidence that these preclinical findings translate to human populations, as exercise reduces withdrawal symptoms and relapse in abstinent smokers (Daniel et al., 2006; Prochaska et al., 2008), and one drug recovery program has seen success in participants that train for and compete in a marathon as part of the program (Butler, 2005). ... In humans, the role of dopamine signaling in incentive-sensitization processes has recently been highlighted by the observation of a dopamine dysregulation syndrome in some patients taking dopaminergic drugs. This syndrome is characterized by a medication-induced increase in (or compulsive) engagement in non-drug rewards such as gambling, shopping, or sex (Evans et al., 2006; Aiken, 2007; Lader, 2008).
Sweden has also begun developing outdoor gyms, called utegym. These gyms are free to the public and are often placed in beautiful, picturesque environments. People will swim in rivers, use boats, and run through forests to stay healthy and enjoy the natural world around them. This is especially possible in Sweden due to its geographical location.[139]
In the present study, we measured muscle endurance by completion of time to exhaustion tests where the subject has to maintain a fix workload for as long as possible. All time to exhaustion tests lasted less than ten minutes, confirming that OLDE was performed at high intensity. The duration of the time to exhaustion tests in the present study is in accordance with previous studies using the same exercise on a different ergometer [11, 17, 18]. Relative reliability refers to the degree to which individuals maintain their position in a sample with repeated measurements [30]. The ICC value of 0.795 can be interpreted as a questionable reliability (ICC < 0.8), close to the threshold for good reliability (0.8 < ICC < 0.9) [19]. However, as no consensus really exists on threshold to interpret ICC results [31], the practical significance of its value has to be determined with caution by the readers according to their future use of the present protocol. Absolute reliability refers to the degree to which repeated measurements vary for individuals [30]. Traditionally, time to exhaustion tests are known to present a greater CV (CV > 10%) than time trials (i.e. subjects has to perform the greater amount of work possible in a fixed time/distance; CV < 5%) [20]. Interestingly, in our study the CV is below 10%, confirming the great reliability of our novel high intensity OLDE protocol to measure muscle endurance, this despite the small sample size, chosen to be in accordance with previously published studies using the same protocol [8, 11, 17]. This great reliability is confirmed by the typical error of measurement value of 0.30 min, corresponding to 5% of the averaged performance value. Finally, as the typical error of measurement value was slightly above the smallest worthwhile change calculated (0.28 min), it is unlikely that our novel high intensity OLDE protocol can be used to detect small differences in performance.
Sensitivity of ACTH and PRL for the detection of OTS was four out of four and five out of five, respectively (table 2; cutoff, 200% at the second exercise test) and for the detection of NFO was four out of five and three out of three, respectively. Sensitivity of cortisol (cutoff, 200% at the second test) and GH (cutoff, 1000%) for the detection of OTS was four out of five and two out of five, and for the detection of NFO, one out of five and two out of four, respectively (table 2).
We’ve gone on the record with our love of MMA conditioning exercises, and that’s why we bookmarked this video. Even the warm-up is jam-packed with explosive movements that’ll get your heart pumping (think high knees and walking front kicks). And once you move into the actual workout, you’re in for even more high-energy exercises, like hopping front kicks, that are sure to condition your body from head to toe.
In 1904, Danish prize-winning athlete and gymnastics educator JP Müller followed Checkley’s exercise philosophy with the publication of ‘My System’. This book described how the relatively healthy, average person could keep fit, fortify health and stamina, and increase physical and mental efficiency with 15 min of daily exercise. He claimed: ‘If people only knew how much more, how much better and how much longer they can enjoy life, instead of being controlled by a weakly body, they have a strong and healthy one at their command!’15 Müller JP. My system. London: Link House; 1904. [Google Scholar] Müller was born a weak child and developed an exercise routine to re-build his own body, inspired by the harmony of ancient Greek statues. His routine included exercising natural functional movements, self-massage of skin in fascial lines, exposure to the sun, and bathing in cold water in addition to running on the balls of the feet as an aerobic activity.15,16 Müller JP. My system. London: Link House; 1904.

Building Strength. Alan Calvert, the Milo bar-bell company, and the modernization of American weight training; PhD thesis. Austin: The University of Texas; 2006. [Google Scholar] This forced both traditional Physical Culture systems to require new professional establishments. Competitive athletes and gymnasts started training under ‘The International Gymnastics Federation’ (established in 1881)13 International Gymnastic Federation (FIG) [Internet]. History of gymnastics. 2015 Aug 30 [cited 2015 Aug 30]. Available from: http://www.fig-gymnastics.com/site/about/federation/history. [Google Scholar] and within the ‘International Olympic Committee’ (established in 1894).14 The Olympic Museum [Internet]. The modern Olympic games. 2014 Dec 16 [cited 2015 Aug 30]. Available from: http://www.olympic.org/Assets/TOM_2013/Visit/Schools/TOM_teaching_list/ENG_The_Modern_Olympic.pdf. [Google Scholar] Concurrently, mind–body enthusiasts migrated to new independent schools, in which pioneers could express their opinions freely and gain popular following. Between 1890 and 1925, at least six new MMB schools emerged, sharing a similar exercise philosophy and practicing similar exercises. These methods, which are the focus of this paper, were led by six charismatic pioneers: Checkley, Müller, Alexander, Randell, Pilates, and Morris.

"With CrossFit growing exponentially, you do get boxes that more closely resemble boutique studios -- think Brick or Solace in New York -- with amenities like fancy shower products, towel service, and coffee and/or smoothie bars," Ages says. "But you're just as likely to encounter one that has a single Trainspotting-style bathroom and a crumbling concrete floor."
Results Maximal blood lactate concentration was lower in OTS compared with NFO, while resting concentrations of cortisol, ACTH and prolactin concentrations were higher. However, sensitivity of these measures was low. The ACTH and prolactin reactions to the second exercise bout were much higher in NFO athletes compared with OTS and showed the highest sensitivity for making the distinction.
