Chronic exercise and skeletal muscle power in older men.
We sought to determine the effects of age and chronic exercise on muscle power in older males. We examined 32 older males 60-74 years of age and grouped as sedentary (CON, n = 11), chronic endurance trained (ET, n = 10), and chronic endurance trained + resistance training (ET + RT, n = 11). Exercise history was obtained by questionnaire. Absolute strength and power measures were obtained by the...
متن کاملSkeletal Muscle
The modulation by internal free [Mg 2 1 ] of spontaneous calcium release events (Ca 2 1 “sparks”) from the sarcoplasmic reticulum (SR) was studied in depolarized notched frog skeletal muscle fibers using a laser scanning confocal microscope in line-scan mode ( x vs. t ). Over the range of [Mg 2 1 ] from 0.13 to 1.86 mM, decreasing the [Mg 2 1 ] induced an increase in the frequency of calcium re...
متن کاملRepairing skeletal muscle: regenerative potential of skeletal muscle stem cells.
Skeletal muscle damaged by injury or by degenerative diseases such as muscular dystrophy is able to regenerate new muscle fibers. Regeneration mainly depends upon satellite cells, myogenic progenitors localized between the basal lamina and the muscle fiber membrane. However, other cell types outside the basal lamina, such as pericytes, also have myogenic potency. Here, we discuss the main prope...

Figure Legend: Figure 1 Skeletal muscle Necrosis in a male F344/N rat from a chronic study. This cross section of skeletal muscle exhibits an extensive, highly fragmented and vacuolated collection of muscle fibers; some are hypereosinophilic, and others are pale. Figure 2 Skeletal muscle Necrosis in a male F344/N rat from a chronic study. Dystrophic mineralization has affected several necrotic ...
