Strength training and cross-sectional area of muscles.
As my friend Dr. R. J. Maughan pointed out in his recent paper in the Journal (Maughan, Watson and Weir, 1984) any discussion of the effect of training on the relationship between the strength and the cross-sectional area of a muscle should take into account the effect of changing the angle of pennation of the muscle fibres. In his discussion Dr. Maughan refers to his finding that, in untrained...
متن کاملMuscle strength and cross-sectional area in man: a comparison of strength-trained and untrained subjects.
This study has examined muscle strength and cross-sectional area in a group of 35 healthy untrained male subjects and 8 subjects who had been engaged in a strenuous weight-training programme. The maximum voluntary knee extension force which could be produced by the untrained subjects was 742 +/- 100 N (mean +/- SD). The trained subjects could produce a significantly (p less than 0.001) greater ...
متن کاملUltrasound measurement of rectus femoris cross-sectional area and the relationship with quadriceps strength in COPD.
BACKGROUND Quadriceps weakness and loss of muscle mass predict mortality in chronic obstructive pulmonary disease (COPD). It was hypothesised that a reduced quadriceps cross-sectional area could be detected by ultrasound in patients with COPD compared with healthy subjects, and that measurements relate to strength and fat-free mass (FFM). METHODS Rectus femoris muscle cross-sectional area (RF...
متن کاملImprovement of Strength Parameters of Sand Reinforced with Polymeric Fibers
Triaxial consolidated drained, unconfined compression, and CBR tests have been conducted in order to study the stress-strain, strength, and volume change characteristics of fine sand specimens reinforced by polymeric fibers made from carpet wastes. The variables are aspect ratio (length/width) and weight percentage of the fibers. The results indicate that the peak strength and total volume chan...
