Video Abstract for the ESSR 45.2 article “Joint Loading in Runners Does Not Initiate Knee Osteoarthritis” from author Ross H Miller. Runners do not have a greater prevalence of knee osteoarthritis (OA) than non-runners. The hypothesis that joint loads in running do not cause OA is forwarded. Two mechanisms are proposed: 1) cumulative load, which is surprisingly low in running, is more important for OA risk than peak load, and 2) running conditions cartilage to withstand the mechanical stresses of running.
Often, when you watch someone lifting weights in a gym, you’ll notice they’re essentially “throwing” the weights up and “dropping” the weights down more than actually “lifting” or “lowering” the weights. They’re allowing certain aspects of physics (momentum, inertia, and gravity) to do much of the work for them instead of truly engaging, and therefore stimulating their muscles. Unfortunately their “perceived” goal is to make the weight move, but the real goal in weight training isn’t just moving the weight; the goal is to fatigue and challenge the targeted muscles. Depending on the specific exercise and range of movement involved, we instruct our clients to take approximately 10 seconds to lift the weight and another 5-10 seconds to lower the weight. By moving slowly, you’re not allowing inertia to carry the weight up or using gravity to let the weight crash down during the lowering phase of the movement. This enhanced and more complete muscle fiber stimulation ensures that you’re not simply “spinning your wheels.” This high-quality exercise stimulus will lead to greater results far quicker than more traditional lifting methods.
I believe we are coming around to the conclusion that what was recommended for years by the medical community (30 minutes of "aerobic exercise" 3-5 times a week, getting the heart rate up to 80% max. for age, etc.) has been inadequate, and of too low an intensity level. When an activity is of sufficient intensity, and not of a certain duration or repeated a certain number of times, the body will initiate a total-body response (metabolic, HDL, glucose tolerance, blood pressure, bone mineral density, immune competency, etc.) It appears that if this level of intensity is never reached, regardless of the amount of time spent or the frequency it is repeated, the beneficial response by the body never occurs, or is at least blunted.
The aims of the present study were to assess the reliability of a novel high intensity OLDE protocol to measure muscle endurance, and to describe the isokinetic muscle fatigue induced by high intensity OLDE and its recovery. We demonstrated that our novel high intensity OLDE protocol can be used as a reliable measure of muscle endurance, and that isokinetic muscle fatigue recovers and plateaus within ~ 30 s following exhaustion. Therefore, the novel high intensity OLDE protocol tested in this study might provide an interesting tool to investigate muscle fatigue and muscle endurance.
Olympic soccer medalist and Fit As A Pro star Lauren Sesselmann is a big fan of the “running pyramid” for 30 seconds. “It’s a mix of cardio and balance that works your whole body. You count from one to ten then ten back down to one with high knees until 30 seconds is up,” she says. “Aim to get your knees up to hip height. Raise right knee, pause. Then raise left knee, followed quickly by the right knee and pause with the right knee still up high. Then do three knees fast and pause.” Continue till you’ve done ten high knees and then back it down to the beginning. The pause will allow you to work on your balance because you are landing quickly with one knee in the air and one the leg on the ground.
What Does the Workout Focus on? – This goes along with matching the exercise video to what you want to work on in your fitness goals. Make sure the exercise video you choose will help you reach the fitness goals you have. For example, if one of your goals is to work on getting flatter abs and there is not an abs exercise on the whole video, this is a major fitness goal that goes untouched. With the variety of exercise videos on the market today, you will be able to find an exercise video that helps you reach your goals.
It's important to note that you can spread your activity into intervals as short as 10 minutes. So if you have a very busy schedule, even doing three, 10-minute aerobic exercises per day, five days per week, will be sufficient. To get you started, here are the different types of exercise, how they benefit the body and what kind of activities they entail:
A Polar (www.polar.fi) heart rate monitor (belt and watch) is used to measure heart rate continuously. A transmitter belt is fastened around the chest while the watch is held by a nearby observer. If at any time during the experiment the heart rate exceeds the predetermined ceiling (85% of age-predicted max heart rate) the experiment should be stopped immediately.
The results of this study present evidence in favor of this high intensity OLDE protocol to investigate muscle fatigue and muscle endurance. Indeed, this new protocol developed in our laboratory i) presents a lower variability than other high intensity time to exhaustion tests , ii) is not limited by the cardiorespiratory system and iii) allows a quick start of neuromuscular testing to fully appreciate the extent of muscle fatigue induced by the exercise. Therefore, it can provide an interesting tool to isolate the cardiorespiratory and neuromuscular effects of various manipulations supposed to play a role in muscle fatigue and performance during high intensity dynamic endurance exercise (e.g. spinal blockade of afferent feedback from the working muscles).
The study that kicked off this whole seven-minute workout fad four years ago notes that the secret-sauce is to strategically work different major muscles groups (upper body, lower body, core) each time you do the workout. This allows for one major muscle group to rest while you work the next muscle group, resulting in a super-efficient, super-effective routine.
1) The biggest critique I have is that transitions from poses are too aggressive and, in many cases, FAR too quick. This could very easily result in stabilizer injury with those healing from core, back, spine or neck injuries or those who don't have the best core strength to begin with. The example that comes to mind is in the 'Sweat" workout. The rapid change from low lunge into a one-foot balanced runner caused an injury for me the first week, and just again today after 6 weeks. If you have ANY history of car crash with spinal involvement, low back problems, abdominal surgery, or core weakness, you MUST listen to your body carefully during these workouts. The modifications are helpful, but they simply decrease the impact of the position once you are in them. The quick transitions in PiYO keep heart rates up, but they also jeopardize the safety of joints or muscles that are a) fatigued from participating and b) unstable due to weakness. Adapt and SLOW DOWN when needed. Better to do 2 sets safely than 4 sets and getting hurt.

In healthy adults, aerobic exercise has been shown to induce transient effects on cognition after a single exercise session and persistent effects on cognition following regular exercise over the course of several months. People who regularly perform aerobic exercise (e.g., running, jogging, brisk walking, swimming, and cycling) have greater scores on neuropsychological function and performance tests that measure certain cognitive functions, such as attentional control, inhibitory control, cognitive flexibility, working memory updating and capacity, declarative memory, spatial memory, and information processing speed. The transient effects of exercise on cognition include improvements in most executive functions (e.g., attention, working memory, cognitive flexibility, inhibitory control, problem solving, and decision making) and information processing speed for a period of up to 2 hours after exercising.

Seven minutes of exercise per day a few times a week though isn’t a magical elixir that will give you a bikini-ready body in a few weeks. Michelle Golla, of Denver-based Boost 180 Fitness, says, “it's important not to set unrealistic expectations for a 7-minute workout. It will not completely transform your body, but it is a great way to get your heart pumping and burn calories all day long when you're pressed for time.”
Do you have any health or physical limitations to consider? If you have back problems, knee issues, arthritis, high blood pressure, asthma, or any kind of health or physical limitations, you need to consider these when looking at the array of exercise videos on the market. There are some that will push you to the very edges of your limits and others that can accommodate a necessity for lower impact and a slower pace yet are still effective. Ignoring health problems or physical limitations is very dangerous. Asking your doctor for any restrictions before shopping is a plus as well.
We recently developed a high intensity one leg dynamic exercise (OLDE) protocol to measure muscle endurance and investigate the central and peripheral mechanisms of muscle fatigue. The aims of the present study were to establish the reliability of this novel protocol and describe the isokinetic muscle fatigue induced by high intensity OLDE and its recovery. Eight subjects performed the OLDE protocol (time to exhaustion test of the right leg at 85% of peak power output) three times over a week period. Isokinetic maximal voluntary contraction torque at 60 (MVC60), 100 (MVC100) and 140 (MVC140) deg/s was measured pre-exercise, shortly after exhaustion (13 ± 4 s), 20 s (P20) and 40 s (P40) post-exercise. Electromyographic (EMG) signal was analyzed via the root mean square (RMS) for all three superficial knee extensors. Mean time to exhaustion was 5.96 ± 1.40 min, coefficient of variation was 8.42 ± 6.24%, typical error of measurement was 0.30 min and intraclass correlation was 0.795. MVC torque decreased shortly after exhaustion for all angular velocities (all P < 0.001). MVC60 and MVC100 recovered between P20 (P < 0.05) and exhaustion and then plateaued. MVC140 recovered only at P40 (P < 0.05). High intensity OLDE did not alter maximal EMG RMS of the three superficial knee extensors during MVC. The results of this study demonstrate that this novel high intensity OLDE protocol could be reliably used to measure muscle endurance, and that muscle fatigue induced by high intensity OLDE should be examined within ~ 30 s following exhaustion.
These leisurely pursuits have their place, but there’s no substitute for the intensity of intervals and strength training or plyometrics. “When you reduce your intensity, athletic performance declines,” he says. “Cardiovascular fitness and other physiological metrics drop off.” Bone density suffers, too — particularly in women. In short, when you stop pushing yourself, you’ll become less fit, less healthy.

* Strength building is an expensive metabolic process. Although we see it as building muscle, our body is making global metabolic adaptations. It is upgrading its metabolic efficiency by synthesizing more enzymes to make metabolism more capable. This includes aerobic metabolism, anaerobic metabolism, gluconeogenesis, glycogen breakdown and transport, blood buffering agents, and of course new muscle fiber growth. All of this new synthesis is extremely metabolically expensive; that is why your body will not make these changes unless an intense stimulus is applied, and the organism is left undisturbed afterwards to make these changes.
Even after long term IV therapy and other holistic type treatments to treat the Epstein Barr virus and co-infections in the blood, I still have CFS/ME. I have found effective ways to work with CFS/ME, yet this is not an overnight process and all of the lifestyle tools come into play even more so here. Visit our supplement page at anytime where we discuss options for immune support. Be sure you are getting enough zinc. This is sometimes overlooked. An additional 20-50 mg. can be helpful with CFS/ME.
Lose yourself in the high-energy rhythm of the Pound Rockout Results System, a five-disc sweatfest in which you wield drumsticks (aka Ripstix) instead of weights. "The drumming takes your mind off your muscles hurting!" one tester marveled. You'll "constantly tap the sticks" in each routine—core, upper body, lower body, intervals, tune-up and jam session—for a "totally unique" cardio blast.
Video Abstract for the ESSR 45.3 Perspectives for Progress “Physical Activity as Cause and Cure of Muscular Pain: Evidence of Underlying Mechanisms” from authors Karen Søgaard and Gisela Sjøgaard. Work-related physical activity (PA), in terms of peak loads and sustained and/or repetitive contractions, presents risk factors for the development of muscular pain and disorders. However, PA as a training tailored to the employee’s work exposure, health, and physical capacity offers prevention and rehabilitation. We suggest the concept of “Intelligent Physical Exercise Training” relying on evidence-based sports science training principles.
Weighing yourself and keeping an exercise journal are two ways to track your progress, but taking your measurements (chest, arms, waist, hips) will give you a little more information. For example, you may be losing inches even if your scale weight doesn't change. In that case, monitoring your measurements every few weeks can reassure you that you are, in fact, slimming down.
Exercise tests were performed on a cycle ergometer (Lode Excalibur Sport, Groningen, The Netherlands) or on a treadmill (Ergo ELG 55; Woodway, Weil am Rhein, Germany) depending on the sport. Tests on the cycle ergometer started with an initial workload of 80 W (subjects 6 and 7) or 30 W (subjects 4 and 9), the workload was increased by 40 W every 3 min. Tests on the treadmill started at 5.4 km h−1, the speed was increased with 1.8 km h−1 each 3 min (subjects 1, 2, 3, 8 and 10). One subject performed the treadmill test with an inclination of 1% (subject 5). The duration of each test was recorded in seconds. Subjects wore a heart rate monitor (Polar Accurex Plus, Kempele, Finland) for determination of maximal heart rate (HRmax) throughout the exercise tests. After each exercise test, 20 μl of blood was drawn from the right earlobe to determine maximal blood lactate concentration ([La]max) with enzymatic analysis (EKF; Biosen 5030, Barleben, Germany).

Int Psychogeriatr. 26 (1): 9–18. doi:10.1017/S1041610213001385. PMID 23962667. Six RCTs were identified that exclusively considered the effect of exercise in AD patients. Exercise generally had a positive effect on rate of cognitive decline in AD. A meta-analysis found that exercise interventions have a positive effect on global cognitive function, 0.75 (95% CI = 0.32–1.17). ... The most prevalent subtype of dementia is Alzheimer’s disease (AD), accounting for up to 65.0% of all dementia cases ... Cognitive decline in AD is attributable at least in part to the buildup of amyloid and tau proteins, which promote neuronal dysfunction and death (Hardy and Selkoe, 2002; Karran et al., 2011). Evidence in transgenic mouse models of AD, in which the mice have artificially elevated amyloid load, suggests that exercise programs are able to improve cognitive function (Adlard et al., 2005; Nichol et al., 2007). Adlard and colleagues also determined that the improvement in cognitive performance occurred in conjunction with a reduced amyloid load. Research that includes direct indices of change in such biomarkers will help to determine the mechanisms by which exercise may act on cognition in AD.
In summary, Kuhn demonstrated substantial evidence in randomized clinical trials that exercise is effective for treating individuals with RCIS, thereby supporting its use in clinical practice. However, as Kuhn indicated, detail related to which specific exercises are best to prescribe is lacking. Thus, it might be premature to label this exercise protocol as a criterion standard based on current available evidence. In addition, the multifactored nature of RCIS indicates that individuals do not present with a homogeneous list of impairments. Therefore, we believe that using the same exercise program to treat everyone who has RCIS is inappropriate. An effective exercise program is derived not only from the pathoanatomic diagnosis but also from the synthesis of factors, such as pain, impairments, and functional limitations. Furthermore, we believe follow-up examinations might be necessary to modify and progress the individual's exercise program. Development of a classification-based treatment approach using evidence-based exercises with standardized exercise dosage and progression guidelines might optimize outcomes for individuals with RCIS.

Exclusion criteria included major diseases or conditions such as severe heart disease, uncontrolled hypertension, obesity, osteoarticular pathology, and neurological disease. Criteria were evaluated on the basis of clinical history, resting ECG, and physical examination. Participants maintained their lifestyles and were instructed not to take part in any other physical programs throughout the study. At the time of the initial design, the study consisted of a 12-week randomized controlled trial with a frequency of 3 times a week, 36 sessions in all, ending with a new assessment of their wellness and the potential persistence of the results on functional/physical capacities.
