The elbow is a “hinge” joint formed by the distal end of the humerus and the proximal ends of the radius and ulna bones. The elbow moves into flexion and extension. The trochlea and capitulum of the humerus articulate with the trochlear notch of the ulna and the radial head, respectively.
The specific articulations of the elbo...
Nowadays, metabolic equivalents (METs) are commonplace on display panels of treadmills, stair climbers, elliptical trainers and other cardiovascular machines, yet METs are often ignored because exercisers simply don’t know what they are or how to use them. This is unfortuna...
I incorporate balance training into clients’ workouts in one of two ways.
Some clients—usually athletes, individuals who are in postrehabilitation and the elderly—understand that they need balance training. With them it’s acceptable to block out 15...
A new service will allow personal trainers to customize workout programs for clients, recommend how-to videos for specific exercises and track their clients’ progress over time via a handheld device and the Internet.
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?
Clients who read about the occasional
athlete who suffers from a fatal incident on the basketball court or football field, or the marathon runner who “blows out his knees,” may ask, is exercise really safe? The best answer to that question is, Exercising is safer than remaining sedentary.
Case Study: Weight Loss
According to the 1999-2000 National Health and Nutrition Examination Survey, more than 64.5 percent of Americans are obese or overweight (Centers for Disease Control and Prevention 2003). It's no wonder, then, that many clients cite weight loss as a main goal when starting a new exercise program. As personal trainers, we want our clients to reach their goals quickly and safely. However, results are sometimes hard to achieve, leading to frustration and dropout. A creative approach may be what's needed.
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.
