Evaluation of the strength-size relationship in vivo using various muscle size indices

Article Abstract:

The size of an anatomical cross-sectional area of a muscle as imaged by magnetic resonance imaging (MRI) can predict the strength of the muscle. This was the conclusion of researchers who analyzed three MRI measures of muscle size in 39 women.

Hemoglobin, muscle oxidative capacity, and VO(sub)2max in African-American and Caucasian women

Article Abstract:

Research reveals differences in maximal oxygen uptake between African-American and Caucasian women and this variation persists even after adjusting for hemoglobin levels, muscle activity, and leg lean tissue volume. Data indicate that all three criteria are lower for African-American women than in Caucasian women.

Muscle metabolic function, exercise performance, and weight gain

Article Abstract:

A study, which would determine the relationship of muscle metabolism to exercise performance and that of exercise performance to the rate of weight gain, is discussed. The findings suggest that muscle anaerobic metabolism influence strength, independent of muscle size, and that aerobic fitness at the muscle and whole body levels and strength influence exercise performance.
