The rate of velocity development associates with muscle echo intensity, but not muscle cross-sectional area in older men
The examination of mechanisms contributing to the age-related reductions in rapid velocity development is limited. The purpose of this study was to examine the influence of muscle cross-sectional area (CSA) and echo intensity (EI) on plantarflexor rate of velocity development (RVD) in older adults....

| description | The examination of mechanisms contributing to the age-related reductions in rapid velocity development is limited. The purpose of this study was to examine the influence of muscle cross-sectional area (CSA) and echo intensity (EI) on plantarflexor rate of velocity development (RVD) in older adults. Twenty-two men (mean ± SD age = 69 ± 3 years) performed three maximal plantarflexion voluntary isokinetic muscle actions at a velocity of 2.09 rad · s
−1
. Peak RVD was determined as the peak derivative of the velocity–time curve from the onset of velocity development to the onset of the load range. B-mode ultrasound was used to examine CSA and EI from the lateral and medial gastrocnemius. Plantarflexor RVD was related to EI (
r
= −0.491,
P
= 0.020), but not CSA (
r
= −0.003,
P
= 0.989). The findings of the present investigation suggest that alterations in muscle tissue composition (i.e., increase in intramuscular fat and/or fibrous tissue) may influence the ability of older adults to rapidly accelerate their limb. |
