The data suggest that gastrocnemius muscle composition alone is not a determinant of shot-putting success. (MM)

The relative endurance performance of women (and low-strength men) is superior to that of high-strength men only at submaximal tension levels below the critical occluding tension level. (MM)

There is a rapid increase in strength in children and gradual decrease after early adulthood. (MM)

There have been many attempts to describe what happens when a muscle gets stronger. However, little has been done to examine possible structural changes at the ultrastructural level when a muscle becomes stronger or hypertrophied. (CK)

Within the scope of this study, the velocity or power per unit body weight exhibited by the subjects on two tests of leg power were not related to each other. (MB)

This definition of flexibility and muscular strength also explores their roles in overall physical fitness and focuses on how increased flexibility and muscular strength can help decrease or eliminate lower back pain. (CB)

Describes the possible causes of delayed-onset muscle soreness (DOMS), which include buildup of lactic acid in muscle, increased intracellular calcium concentration, increased intramuscular inflammation, and muscle fiber and connective tissue damage. Proposed methods to reduce DOMS include warming up before exercise and performing repeated bouts…

The purpose of this study was to determine the extent to which a non-traditional strength training program will impact the health-related fitness of youth. Researchers hypothesized that the strengthening program would positively affect the fitness outcomes. Participant physical education classes incorporated strengthening exercises three days…

This report summarizes analyses of 2007-2008 Austin Independent School District students' academic performance on the state-mandated test to their performance on a fitness assessment.
