Aging is commonly associated with a loss of muscle mass and strength, resulting in falls, functional decline, and the subjective feeling of weakness. [] Key Method A cross-section of 40 high-level recreational athletes ("masters athletes") who were aged 40 to 81 years and trained 4 to 5 times per week underwent tests of health/activity, body composition, quadriceps peak torque (PT), and magnetic resonance imaging of bilateral quadriceps.

Leg Strength Declines With Advancing Age Despite Habitual Endurance Exercise in Active Older Adults

The data support newer exercise guidelines for older Americans suggesting resistance training be an integral component of a fitness program and that running alone was not sufficient to prevent the loss in muscle strength (dynapenia) with aging.

Anthropometric, physical function and general health markers of Masters athletes: a cross-sectional study

Examination of measures of anthropometric, physical function and general health markers in the male and female Masters athletes who competed at the 2014 Pan Pacific Masters Games held on the Gold Coast, Australia may suggest that participation in Masters sport helps to maintain anthropometry,Physical function andgeneral health in middle-aged and older adults.

Muscle disuse; the culprit of sarcopenia? A study in master athletes

Sarcopenia is described as the result of a slow but progressive age-related loss of skeletal muscle mass which is reflected by a reduction in the force and power generating capacity of the remaining

Nutrition for Older Athletes: Focus on Sex-Differences

The most important hormonal alterations occurring during aging pertaining regulation of appetite, glucose homeostasis and energy expenditure and the modulatory role of exercise training are described and nutritional aspects that may support health and physical performance for older athletes are highlighted.

Resistance Exercise with Older Fallers: Its Impact on Intermuscular Adipose Tissue

There is no decrease in thigh IMAT after a three-month exercise intervention in older adults at risk for falling and no benefit to eccentric training over traditional resistance training for reducing IMAT in these individuals.

The Aging Athlete: Paradigm of Healthy Aging.

This review provides a physiological basis for the elite performances seen in masters athletes, as well as the health implications of lifelong exercise with a focus on VO2max, skeletal muscle metabolic fitness, whole muscle size and function, single muscle fiber physiology, and communicative properties of skeletal muscle.

Does Chronic Exercise Attenuate Age-Related Physiological Decline in Males?

It is suggested that life-long exercise is associated with favorable body composition and attenuation of the age related decline in testosterone.

Long-term high-level exercise promotes muscle reinnervation with age.

The data show that long-term physical activity promotes reinnervation of muscle fibers and suggest that decades of high-level exercise allow the body to adapt to age-related denervation by saving otherwise lost muscle fibers through selective recruitment to slow motor units.

Sarcopenia, Dynapenia, and the Impact of Advancing Age on Human Skeletal Muscle Size and Strength; a Quantitative Review

The aim of this review is to present current knowledge of the decline in human muscle mass and strength with advancing age and the associated risk to health and survival and to review the underlying changes in muscle characteristics and the etiology of sarcopenia.



Attenuation of skeletal muscle and strength in the elderly: The Health ABC Study.

It is demonstrated that the attenuation values of muscle on computed tomography in older persons can account for differences in muscle strength not attributed to muscle quantity.

Longitudinal study of muscle strength, quality, and adipose tissue infiltration.

Loss of leg MT in older adults is greater than muscle CSA loss, which suggests a decrease in MQ, and aging is associated with an increase in IMF regardless of changes in weight or SF.

Strength, but not muscle mass, is associated with mortality in the health, aging and body composition study cohort.

Low muscle mass did not explain the strong association of strength with mortality, demonstrating that muscle strength as a marker of muscle quality is more important than quantity in estimating mortality risk.

Effects of Resistance Training on Older Adults

Strength and muscle mass are increased following resistance training in older adults through a poorly understood series of events that appears to involve the recruitment of satellite cells to support hypertrophy of mature myofibres.

Thigh Muscle Strength in Senior Athletes and Healthy Controls

In conclusion, senior athletes who participate in highly competitive exercise have greater strength than healthy aged-matched individuals who do not, and neither group displayed the expected strength losses with aging.

The Aging of Elite Male Athletes: Age-Related Changes in Performance and Skeletal Muscle Structure and Function

It is surprising that the performance of elite athletes in all sports appears to be impaired before the onset of the fiber loss, as for the general population, age-related muscle atrophy begins at about 50 years of age.

Age-Related Rates of Decline in Performance among Elite Senior Athletes

Even the healthiest examples of musculoskeletal aging experience significant performance declines around age 75 years, which may be a key time point for preventive intervention to address declining performance.

Age changes in body composition revealed by computed tomography.

Although fat mass was only slightly less in older men, there were clear distributional differences in fat between the age groups, and analysis of fat accumulation between muscles of the abdomen and leg indicated fat infiltration into lean tissue in the older men.

Physical activity as a preventative factor for frailty: the health, aging, and body composition study.

It is suggested that participation in self-selected exercise activities is independently associated with delaying the onset and the progression of frailty, and regular exercise should be further examined as a potential factor in frailty prevention for older adults.

Thigh composition in young and elderly men determined by computed tomography.

Comparisons of relative leg muscle strength between young and elderly men may be misleading due to the decrease in actual muscle tissue associated with ageing, and appropriate quantification of muscle size and CSA must be carried out before such comparisons can be meaningful.
