Peripheral impairments cause a progressive age-related loss of strength and velocity-dependent power in the dorsiflexors.

Muscle power is more functionally relevant than static muscle strength, particularly with aging. However, the effect of age on power derived from isotonic contractions has been studied sparingly, and it has not been studied at all in subjects >75 yr of age. Thus the purpose was to investigate the magnitude and causes of age-related losses in isotonic power among 13 young (26 yr), 13 old (65 yr)...

Sex differences with aging in the fatigability of dynamic contractions.

This study determined the sex difference with aging in fatigability of the elbow flexor muscles during a dynamic fatiguing task, and explored the associated mechanisms. We compared fatigability of the elbow flexor muscles in 18 young (20.2 ± 1 years: 9 men) and 36 old adults (73.5 ± 1 years: 16 men) during and in recovery from repeated dynamic contractions (~60°/s) with a load equivalent to 20%...

Age differences in knee extension power, contractile velocity, and fatigability.

The purposes of this study were to examine age and gender differences in knee extensor strength, power, and fatigue using open- and closed-chain testing procedures. We tested the hypothesis that specific strength (strength/unit muscle mass) would not differ by age, whereas age differences in specific power and fatigue would remain consequent to blunted maximal contractile velocity. Skeletal mus...

Fatigability and recovery of arm muscles with advanced age for dynamic and isometric contractions.

This study determined whether age-related mechanisms can increase fatigue of arm muscles during maximal velocity dynamic contractions, as it occurs in the lower limb. We compared elbow flexor fatigue of young (n=10, 20.8±2.7 years) and old men (n=16, 73.8±6.1 years) during and in recovery from a dynamic and an isometric postural fatiguing task. Each task was maintained until failure while suppo...

Sex-related Differences of Fatigability during Isotonic Concentric Contractions of the Plantar Flexors in Humans

iii Acknowledgements I would like to thank Dr. Dalton for helping me to fully examine the sex-related differences of fatigue. I am sincerely grateful for all of the discussion, troubleshooting, teaching, and editing that, in its final form, is displayed through this thesis. It was a privilege to have such an excellent professor to guide me through the strenuous, but rewarding process. I would a...
