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?
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.
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.
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.
TThe multiarticular complex of the shoulder gives rise to the dynamic movement potential of the arm at the glenohumeral joint. If it were not for the physiological necessity of the scapulo-thoracic “joint” (discussed in the previous Fine Anatomy column, “The Shoulder Girdle,” IDEA Personal Trainer, October 2003, p.36) and its role during abduction or flexion of the upper limb to elevate, rotate, tilt and swivel, the elementary movements of the arm would be greatly limited.
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.
With ArthritisBy Johndavid Maes and Len Kravitz, PhDLearning Objectives
After reading this article, readers should be able to:
Describe what arthritis is and the most common types.
Discuss the nationwide impact of this problem.
Describe the most common symptoms of this disease.
Discuss some of the myths and misunderstandings of arthritis.
State the appropriate exercise approach for those suffering from arthritis.
Proper screening and risk stratification of clients who are starting exercise programs is important for promoting exercise safety and preventing adverse events during exercise. Personal fitness trainers (PFTs) must be able to utilize the proper tools and understand the information gathered from the preexercise screening. Components of this screening include the health history questionnaire (HHQ); physical activity readiness questionnaire (PAR-Q); risk stratification; and informed consent.
