Inactivity, age, and exercise: single-muscle fiber power generation.
We examined the effects of mild therapeutic exercise during a period of inactivity on size and contractile functions of myosin heavy chain (MHC) type I (n = 204) and type II (n = 419) single fibers from the medial gastrocnemius in three age groups. Young adult (5-12 mo), middle-aged (24-31 mo), and old (32-37 mo) F344BNF1 rats were assigned to one of three groups: weight-bearing control, non-we...
متن کاملDoes exercise-induced muscle damage play a role in skeletal muscle hypertrophy?
Exercise-induced muscle damage (EIMD) occurs primarily from the performance of unaccustomed exercise, and its severity is modulated by the type, intensity, and duration of training. Although concentric and isometric actions contribute to EIMD, the greatest damage to muscle tissue is seen with eccentric exercise, where muscles are forcibly lengthened. Damage can be specific to just a few macromo...
متن کاملSingle muscle fiber adaptations with marathon training.
The purpose of this investigation was to characterize the effects of marathon training on single muscle fiber contractile function in a group of recreational runners. Muscle biopsies were obtained from the gastrocnemius muscle of seven individuals (22 +/- 1 yr, 177 +/- 3 cm, and 68 +/- 2 kg) before, after 13 wk of run training, and after 3 wk of taper. Slow-twitch myosin heavy chain [(MHC) I] a...
متن کاملMuscle fiber characteristics of competitive power lifters.
To examine the skeletal muscle characteristics of power lifters, 5 competitive power lifters (PL; X +/- SE; age = 31.0 +/- 1.5 years, squat = 287.7 +/- 15.7 kg, bench press = 170.5 +/- 17.7 kg, and deadlift = 284.2 +/- 7.5 kg) and 5 untrained control subjects (CON; age = 27.3 +/- 3.3 years) served as subjects. Isokinetic squat force and power was greater (p < 0.05) for the PL at all bar velocit...
متن کاملDoes skeletal muscle fiber branching play a role in the inability of old EDL dystrophic muscle to resist large passive stretches?
TO THE EDITOR: Hakim et al. (3) examined the passive mechanical properties of fast-twitch extensor digitorum longus (EDL) muscles from young and old mdx dystrophic mice. They elegantly showed that by increasing passive strain on the dystrophic muscle from 110% of optimal length (Lo) to 160% of Lo, the muscle physically ruptured in a manner that got progressively worse with age. At the oldest ag...
