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.
Circuit Training. Some gyms are set up to move people from machine to machine or exercise to exercise with little rest. This keeps the heart pumping and the muscles working. Work at each station for 30 to 45 seconds, or a certain number of reps, and keep the rest periods short, just the time it takes to walk from station to station. Like with supersets, this method combines the benefits of strength training and a bit of cardio at the same time Similarity in adaptations to high-resistance circuit vs. traditional strength training in resistance-trained men. Alcaraz, P.E., Perez-Gomez, J., Chavarrias, M., et al.

Physical performance and cardiovascular responses to an acute bout of heavy resistance circuit training versus traditional strength training. Alcaraz, P.E., Sanchez-Lorente, J., Blazevich, A.J.

It's easy to do a simple circuit at home, too: Lunges from wall to wall, sit ups in front of the TV, incline push ups on the coffee table, lateral hops over the sleeping puppy — work hard, move quick, get fit!

The simplest way to workout at home is to use your own body. There are a variety of effective body weight exercises that can help you build strength, endurance and burn calories. The downside is that, without added resistance, it's tough to work hard enough to really challenge your body and burn calories. One way around that problem? Circuit training. By going from one exercise to the next, without little or no rest, you keep your heart rate up, burn more calories and get the most out of your exercise time.
I read "Superslow: The Ultimate Exercise Protocol" back in 2000. Then relatively new to learning about exercise and bodybuilding I found it to be a truly fascinating and very challenging read. Not only was the material challenging in the intellectual sense but also in a philosophical sense. It was turning much of what I believed about "exercise" upside down. So meatheads and gym-rats be warned, "Superslow" is a highly technical book that the typical bodybuilder or exercise enthusiast would find "boring" (see other reviews here on Amazon) because it isn't full of ridiculous promises about gigantic, ripped muscles and marketing jargon for selling supplements. What it is is a very thorough analysis of the variety of benefits one can derive (regardless of their limited genetics) from properly performed exercise and the many proven pitfalls associated with a low-intensity and high workload/volume. The book also provides an in-depth history lesson on the continually evolving refinements to Arthur Jones' Nautilus principles. Hutchins' dogged determination to continually seek a safer and more effective way for people to exercise is admirable and shows his devotion to sound scientific principles.
Circuit training tips for beginners: my advice here depends on how physically demanding the circuit is. If you’re just getting into working out and you want to circuit train, start with some less challenging exercises as part of your circuit and consider decreasing the time from a minute for each circuit to 30 seconds (or whatever you’re comfortable and able to finish the circuit with). The same advice applies here as in some of the other sections above: it’s good to build a baseline level of strength and aerobic fitness before circuit training, but it also depends on your level of fitness when you start.
If watching Dancing With the Stars inspired you to get grooving, you should definitely try this DVD for a guided shape-up. Although I suggest shutting your curtains and banishing anyone else from the house while you shake it, learning the routines kept me focused and by the end, I was sweating and laughing (at myself). Skimpy sequined outfits and B-list celebs not required.
Torque signal and knee angle signal were recorded using the same dynamometer as for the OLDE (Cybex NORM isokinetic dynamometer, CMSi, Computer Sports Medicine Inc., Stoughton, USA). During the tests a two shoulder harnesses and a belt across the abdomen limited extraneous movement of the upper body. Torque signal and knee angle signal were digitized on-line at a sampling frequency of 1 kHz using a computer, and stored for analysis with commercially available software. Torque signal was filtered prior to data analysis (Butterworth low-pass filter at 100 Hz). Torque signal, knee angle signal and EMG signal were recorded with the same device (MP150, Biopac Systems Inc., Goleta, USA) and analyzed with the same commercially available software (Acqknowledge 4.2 for MP Systems, Biopac Systems Inc., Goleta, USA).
Alert: Companies strictly follow their exercise rules and deadlines, and courts tend to side with them. See, for example, Deal v. Consumer Programs, Inc. (2006), decided by the 8th Circuit Court of Appeals. The court ruled that the mere submission of a written notice to exercise stock options may be insufficient when the grant agreement states that the notice must be "accompanied by full payment of the purchase price of the shares."
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.

Bottom line. Muscle confusion is a snappy term for non-linear periodization, which simply means rotating the workouts you do so that your muscles are constantly challenged and you get better, faster toning and weight-loss results. Research suggests this approach is more effective than doing the same exercise routine. P90X is a 90-day plan that combines strength moves, cardio, and yoga­—and if you follow it faithfully, you will probably see results. But it’s suitable only for those who are already very fit because the routines are intense and take about an hour a day. Note: You’ll also need dumbbells, exercise bands, and a pull-up bar, which do not come with the basic system. The diet is complicated, but it provides an appropriate number of calories for the work you’ll be doing.
Biomarkers of inflammation such as C-reactive protein, which are associated with chronic diseases, are reduced in active individuals relative to sedentary individuals, and the positive effects of exercise may be due to its anti-inflammatory effects. In individuals with heart disease, exercise interventions lower blood levels of fibrinogen and C-reactive protein, an important cardiovascular risk marker.[28] The depression in the immune system following acute bouts of exercise may be one of the mechanisms for this anti-inflammatory effect.[27]

Perception of effort, defined as “the conscious sensation of how hard, heavy, and strenuous exercise is” [23, 24], was measured during the incremental test (at the end of each minute) and during the time to exhaustion tests (at the end of the warm-up and every 30 s) using the 15 points RPE scale (Borg 1998). Standardized instructions for the scale were given to each subject before the warm-up. Briefly, subjects were asked to rate how hard they were driving their leg during the exercise (leg RPE [8, 24, 25]). Subjects were also asked to not use this rating as an expression of leg muscle pain (i.e., the intensity of hurt that a subject feels in his quadriceps muscles only).

Hessel J [Internet]. Joseph H. Pilates biography. 2015 Jul 8 [cited 2015 Aug 30]. Available from:  He claimed that ‘sports are wonderful … but of little value for correcting whats wrong with you … corrective exercise is the only way to build a beautiful, strong, youthful body.’44 Readers Digest [Internet]. Ray MB. Cutting a fine figure (1934). 2012 Dec 13 [cited 2015 Aug 30]. Available from: [Google Scholar] He explained in his 1939 book ‘Your Health’: ‘Practically all human ailments are directly traceable to wrong habits which can only be corrected through the immediate adoption of right (natural, normal) habits’ … ‘the present day efforts of our so-called health departments are in vain so far as physical health is concerned’ … ‘this condition will prevail until such time as marks the recognition of a standard formation of sound and sane physical culture, based upon the natural laws of life.’45 Pilates J. Your health. Nevada: Presentation Dynamics; 1934. [Google Scholar] In his 1945 book ‘Return to Life Through Contrology,’ Pilates clearly supported Checkley, Müller, and Alexander stating that ‘Contrology is not a system of haphazard exercises designed to produce only bulging muscles’ … ‘Rather, it was conceived to limber and stretch muscles and ligaments so that your body will be as supple as that of a cat and not muscular like the body of a brewery-truck horse.’46 Pilates J, Miller WJ. Return to life through Contrology. Nevada: Presentation Dynamics; 1945. [Google Scholar] In this book, Pilates presented a list of 34 full-body equipment-free exercises, which if performed regularly at home, were promised to ‘give you suppleness, natural grace, and skill that will be unmistakably reflected in the way you walk, in the way you play, and in the way you work’ … ‘You will find your body development approaching the ideal, accompanied by renewed mental vigor and spiritual enhancement’. Pilates famously stated: ‘Physical fitness is the first requisite of happiness.’46 Pilates J, Miller WJ. Return to life through Contrology.

OurBloomFIT & MamaFIT classes provide expecting and postnatal mamas with a safe but sweaty, 40-minute workout. Our classes are safe, vigorous and will increase your athletic ability for a stronger pregnancy and a faster postpartum recovery. We like to think of it as personal training in a community based atmosphere. Classes are intentionally kept small [no more than 10 mamas] so that our instructors can keep a close eye on every mama’s form, breathing technique and overall fitness ability.
Many exercise interventions have been conducted under controlled laboratory conditions [9], but we do not know how older adults prefer to exercise when they are not under controlled settings and are free to choose type, location and social setting (e.g. alone vs. together with others) of exercise. Furthermore, it has been shown that high-intensity interval training (HIIT) can induce superior changes in health-related markers compared to continuous moderate-intensity training (MCT) [10–13], also in older adults [14, 15]. The scientific interest in HIIT has greatly increased during recent years [9], but larger and longer studies under free-living conditions are needed to investigate whether HIIT is feasible as a public health strategy among older adults [9, 16]. Therefore, detailed information about older adults exercise patterns with MCT versus HIIT outside laboratory conditions is of particular interest.
We prefer 1-min incremental exercise testing on a cycle ergometer rather than constant work studies because of its speed, repeatability, and ease of identification of the anaerobic threshold. Although values such as VO2 and anaerobic threshold from both types of studies are reported to be comparable, we questioned whether VD/VT and AaPO2, which depend on simultaneous arterial blood and mixed ...

VO2peak improved in overweight and obese males (pre and post values in L/min, respectively; W = 3.2 ± 0.6 vs. 3.7 ± 0.5, p < 0.001; O = 3.6 ± 0.6 vs. 3.8 ± 0.6, p = 0.013) as well as in overweight females (2.0 ± 0.3 vs. 2.3 ± 0.4, p < 0.001). VO2peak in the first ventilatory threshold (VT1) increased for all 4 interventions in males (p < 0.05), except for S in the obese group (1.6 ± 0.2 vs. 1.7 ± 0.3, p = 0.141). In females, it increased in E (0.9 ± 0.2 vs. 1.4 ± 0.3, p < 0.001), SE (0.9 ± 0.2 vs. 1.2 ± 0.4, p = 0.003), and PA (0.9 ± 0.1 vs. 1.2 ± 0.2, p = 0.006) in overweight groups. Time-to-exhaustion improved in all subjects except for females in PA group (15.7 ± 0.3 min vs. 15.9 ± 0.3 min, p = 0.495).
