This study of 10 seven- to nine-year-old boys was undertaken to determine the electromyographic activity of four muscles in the supporting leg during one foot static balancing. Results are presented and analyzed. (Author/MT)

A 12-week structured rehabilitation program featuring warm-up exercises, increased aerobic exercise, cool down, and home-based continuation of exercise helped 12 children with surgically corrected congenital heart disease improve lower extremity strength and flexibility. (Author/CB)

Information regarding the use of anabolic steroids by athletes should be presented in high school and college health education classes. The use and effects of steroids is described. (MT)

This study determined the effects on the rate at which the handgripping muscles in college-age females develop force when they are fatigued to 80, 60, and 40 percent of their original maximal strength level. (JMK)

Because of the continued prevalence of rapid weight reduction by wrestlers, this study attempted to determine if college wrestlers' strength and muscular endurance were affected by either rehydration or dehydration. Results showed that a loss of five percent of body weight over three days did not affect strength or endurance levels. (JMK)

The effects of three resistance training programs on male college students' muscular strength and absolute and relative muscular endurance were investigated. Results show that human skeletal muscle makes both general and specific adaptations to a training stimulus, and that the balance of these adaptations is to some extent dependent upon the…

The horsepower of the knee flexors and extensors of sprint-trained runners and long distance runners is compared. (MM)

Aerobic training develops efficient catabolic responses in large muscles. (JD)

This study investigated the construct and concurrent validity of a 12-minute crawl stroke swim as a field test of swimming endurance. It was found to be valid. (JD)

This study of high sustained heart rates observed during circuit weight training involving high resistance and low repetitions indicates that such training has no concurrent cardiovascular training effect. (MB)

This article describes successful efforts by physical education teachers at Elberton Elementary School (GA) to construct an affordable pull-up board that could be used to help improve students' arm and upper body strength. An explanation is given of how to use the machine, and the benefits to students are briefly discussed. (IAH)

This study examined the effects of resistance exercise and anabolic steroids on lipoprotein profiles of female weightlifters. The study found that women who participate in resistance training have better lipoprotein profiles than their sedentary counterparts, but these changes do not offset the deleterious effects of steroid use.

When students analyze and present original data they have collected, and hence have a cultivated sense of curiosity about the data, student learning is enhanced. It is often difficult to provide students an opportunity to practice their skills, use their knowledge, and gain research experiences during a typical course laboratory. This article…
