Changes in blood lactate and muscle activation in elite rock climbers during a 15-m speed climb.

abstract：PURPOSE:This pilot study investigated differences in lean tissue mass, muscle strength, muscle quality (strength per unit of muscle mass; MQ), and functional performance in healthy younger and older individuals. The most robust predictors of appendicular lean mass (ALM) were then determined in each group. METHODS:Fift...
