Aerobic exercise is a decisively important component of any fitness program. However, establishing and maintaining ideal exercise intensities for optimally safe and effective workouts can prove challenging for both exercisers and fitness professionals.
In designing cardiorespiratory exercise programs, it is meaningful to consider that many people engage in aerobic exercise to control...
No pain, no gain? This popular adage may not ring true for whole-body vibration (WBV), a new training method that has been used widely in Europe. WBV training has been shown to increase muscular strength, explosive power and anabolic hormone levels when performed for as little as 4 minutes three times a week (Bosco et al. 2000; Torvinen et al. 2002). It requires relatively little exertion...
Just pick up a recent trade magazine and you are almost sure to read about a new exercise program that will accelerate the rate at which you burn fat after you complete a workout. Although this promise is enticing to the exerciser seeking optimal weight loss, rarely is there any scientific evidence validating a particular workout’s postexercise capability to “incinerate fat.”
Conflict in the fitness workplace is inevitable, but it doesn’t have to be harmful. Healthy conflict exists in relationships based on trust and respect, and without conflict, teams may be unable to make effective progress or create a shared vision of the future.
How Does Talking Affect Heart Rate During Exercise?
Mistretta, J.L., et al. 2004. Medicine & Science in Sports & Exercise, 36 (5, Suppl.), S4.
Background. Social opportunities during exercise—such as having a partner for conversation—provide a distraction and may encourage adherence. As long as exercise intensity is sufficient relative to participants’ fitness levels, benefits can be derived.
Thacker, S.B., et al. 2004. The impact of stretching on sports injury risk: A systematic review of the literature. Medicine & Science in Sports & Exercise, 36 (3): 371–8.
Purpose. Researchers at the National Center for Injury Prevention and Control and the National Center for Chronic Disease Prevention and Health Promotion systematically reviewed the research literature in order to assess whether stretching effectively prevents sports injuries and to make recommendations for research and prevention.
McCully, K.K., et al. 2004. Muscle metabolism with blood flow restriction in chronic fatigue syndrome. Journal of Applied Physiology, 96, 871-8.
Study. Exercise physiologists at the University of Georgia set out to determine whether chronic fatigue syndrome (CFS) is associated with reductions in blood flow and muscle oxidative metabolism.
As a personal trainer, you probably know that exercise has been shown to increase bone strength, as measured by bone mineral density (BMD), in people of all ages. But did you know that the degree to which exercise improves BMD depends on a variety of factors, including age, reproductive hormone status, nutritional status and the nature of the exercise?
