The effects of rest intervals on jumping performance: a meta-analysis on post-activation potentiation studies.

abstract：:We aimed to assess the cardiovascular responses and locomotory demands of male referees during diverse elite, international, basketball matches, and to investigate the influence of moderating factors (competition sex, level and stage) on these demands. Cardiovascular and locomotory responses were monitored in 123 elit...
