Inactivity is a recognized compounding factor in sarcopenia and muscle weakness in old age. However, while the negative effects of unloading on skeletal muscle in young individuals are well elucidated, only little is known about the consequence of immobilization and the regenerative capacity in elderly individuals. Thus the aim of this study was to examine the effect of aging on changes in muscle contractile properties, specific force, and muscle mass characteristics in 9 old (61-74 yr) and 11…

Effects of aging on muscle mechanical function and muscle fiber morphology during short-term immobilization and subsequent retraining.

The present data reveal that OM may be more susceptible to the deleterious effects of short-term muscle disuse on muscle fiber size and rapid force capacity than YM, and seems to require longer time to recover and regain rapid muscle force capacity, which may lead to a larger risk of falling in aged individuals after periods of short term disuse.

Skeletal muscle adaptations to physical inactivity and subsequent retraining in young men

The results indicate that the loss of muscle force with 3-week unloading in humans is mostly explained by muscle atrophy and by a decrease in myosin content and all the neuromuscular changes induced by this model of disuse can be fully restored after a resistance training intervention of equal duration.

Effects of aging on unloading-induced skeletal muscle atrophy and subsequent recovery in rats

Various suggestions can be deduced from experimental evidence as guidelines for the development of a combined intervention of exercise, nutrition and physical therapies that effectively maintain skeletal muscle as healthy as possible in aged individuals under unloading condition.

A reduced activity model: a relevant tool for the study of ageing muscle

This step-reduction model may be more relevant than total bed rest or limb immobilisation for examining real-world scenarios that present a physiological challenge to the maintenance of skeletal muscle mass in older individuals.

Role of the nervous system in sarcopenia and muscle atrophy with aging: strength training as a countermeasure

Strength training appears to elicit effective countermeasures in elderly individuals even at a very old age by evoking muscle hypertrophy along with substantial changes in neuromuscular function, respectively, and leads to an improved functional capacity during activities of daily living.

Effects of age on muscle power, postural control and functional capacity after short-term immobilization and retraining

Two weeks of lower limb immobilization led to decreases in maximal muscle power in both young and old, whereas postural control was impaired selectively in old men.

Mechanical muscle function, morphology, and fiber type in lifelong trained elderly.

Muscle fiber size and mechanical muscle performance, particularly RFD, were consistently elevated in aged individuals exposed to chronic strength training and may provide an important physical reserve capacity to retain muscle mass and function above the critical threshold for independent living at old age.

Skeletal muscle weakness in old age: underlying mechanisms.

Much of the age-associated muscle atrophy and declining strength may be explained by motor unit remodeling which appears to occur by selective denervation of muscle fibers with reinnervation by axonal sprouting from an adjacent innervated unit.

The purpose of this clinical commentary is to identify the major effects of age and inactivity on skeletal muscle structure and function, and discuss potential therapeutic interventions, with special emphasis on how alterations in muscle structure affect function.

Skeletal muscle function and hypertrophy are diminished in old age

Age-associated muscle weakening is associated with a decline in muscle mass and function and at advanced age, the hypertrophic response is reduced and a hypertrophic stimulus even aggravates the age‐ associated muscle weakening.

Effect of age on muscle hypertrophy induced by resistance training.

Age can attenuate the hypertrophic response of muscle groups to resistance training, when the training load is proportional to baseline strength, however, aging does not impair training-induced increases in specific tension.

Resistance training induces qualitative changes in muscle morphology, muscle architecture, and muscle function in elderly postoperative patients.

The effectiveness of resistance training is demonstrated to induce beneficial qualitative changes in muscle fiber morphology and muscle architecture in elderly postoperative patients in contrast to rehabilitation regimes based on functional exercises and neuromuscular electrical stimulation, which had no effect.

Effect of resistance training on skeletal muscle-specific force in elderly humans.

Muscle-specific force in vivo following strength training in old age is assessed, highlighting the effectiveness of strength training for increasing the intrinsic force-producing capacity of skeletal muscle in oldAge.

The effect of ageing and immobilization on structure and function of human skeletal muscle fibres.

Myosin concentration is a major determinant of the lower Po/CSA of single fibres in ageing and especially following immobilization, whereas immobilization is associated with higher Vo in the absence of a change in myosin function.

Immobilization effects in young and older adults

YM and OM experienced similar losses in strength, yet muscle volume loss was only significant in OM, and muscle activation strategies appear to preserve strength during atrophy.

Differential effects of reduced muscle use (hindlimb unweighting) on skeletal muscle with aging

The majority of old rats had difficulty with ambulation following unweighting, suggesting that the functional consequences of reduced weight-bearing are greater in old than in young animals.
