People of all ages can improve the quality of their lives and reduce the risks of developing coronary heart disease, hypertension, some cancers and type 2 diabetes with ongoing participation in moderate physical activity and exercise. Daily exercise will also enhance one’s mental well-being and promote healthy musculoskeletal function throughout life. Although habitual physical activity is an a…Read More
Weight management programs abound,
and they employ countless strategies and
approaches. But all these programs
should include three principal components:
(1) an exercise plan that incorporates
cardiovascular and resistance
training to increase caloric expenditure and
maintain muscle mass; (2) a lifestyle/
dietary approach that emphasizes balanced
nutrition and decreased caloric …

Flexibility training has been promoted for decades as an integral part of fitness that may help decrease the risk of injuries; release pain associated with musculoskeletal stiffness; and improve sport-specific performance when range of motion (ROM) is essential. Wh…Read More
Statistics demonstrate that countries around the globe are experiencing a spectacular increase in obesity. Worldwide there are an estimated 1 billion obese persons (body mass index [BMI] ≥ 30), and the number has been increasing rapidly over the last two decades (Loos & Bouchard 2003). In the United States 65% of adults are overweight (BMI = 25–29.9), and of these, 31% are obese…Read More
As you “retool” and re-educate yourself to prepare for new career opportunities and challenges in the 21st century, you may decide to focus on fitness for older adults. With this clientele, preventing falls is a major issue. Research has clearly shown that exercise is…Read More
Numerous recreational exercisers complete their
cardiovascular and strength training workouts either during the same training session or within hours of each other. This sequential exercise regime is referred to as “concurrent training.” The question often asked of personal fitness trainers (PFTs) is whether performing cardiovascular exercise prior to strength training will compromise the strength training performance. A recent publication by Sporer and Wenger (2003) addresses this question, as well as some related training issues.
Walking Intensity and Bone Mineral Density
Fogleman, K.M., Borer, K.T., & Sowers, M.R. 2003. Walking intensity stimulates increases in BMD in post-menopausal women. Medicine & Science in Sports & Exercise, 35 (5, Supplement), Abstract 95.
Menopause is often associated with a loss in bone mineral density (BMD). Although exercise has been shown to increase BMD in postmenopausal women, the exact mechanism is presently unclear, as are the intensity and types of exercise that will elicit this response.
Inactivity is taking its toll on human beings. As fitness professionals, we are keenly aware that society is fascinated with the human body—with losing fat, specifically—and yet, getting people to exercise is still a major obstacle. Obesity, a significant and growing health problem, has been associated with heart disease, diabetes, hyperlipidemia, hypertension and hyperinsulinemia, among…Read More
