Leisure-time physical activities and their relationship to cardiorespiratory fitness in halthy men and women 18-95 years old

Article Abstract:

Results show an inverse relationship between leisure-time physical activities (LTPA) and age in both sexes. This suggests that LTPA remotely influences aerobic capacity.

Age and gender responses to strength training and detraining

Article Abstract:

Gender and age responses to strength training and detraining have been studied with the finding that changes in one-repetition maximum (1RM) strength in response to strength training (ST) and detraining are affected by age. ST-induced increases in muscular strength, however, seem to be maintained equally well in young and older males and females in 12 weeks of detraining. They are maintained above baseline levels even after 31 weeks of detraining in young men, young women and older men. One-repetition maximum and isokinetic strength was measured in 18 young and 23 older people before and after unilateral knee extension ST and after detraining periods.

A more efficient magnetic resonance imaging-based strategy for measuring quadriceps muscle volume

Article Abstract:

Research points out that selection of a 3.1 centimeter between axial magnetic resonance imaging sections is ideal in the quadriceps measurement for muscle volume. Data indicate that the procedure yields adequate precision and detects small changes in the muscle volume.
