This test evaluates anaerobic power, utilizing
stretch-shortening cycle actions of the lower extremities to
induce and evaluate fatigue from the contact time between
jumps. This methodology facilitates detection of a possible
increase in anaerobic capacity. In accordance with the aim
of this study, anaerobic capacity was tested by an ‘‘all out’’
60-second countermovement jump test (60CMJ). Different
authors have confirmed that the 60CMJ test is an exercise
with supra-maximal characteristics, during which 70—85% of
the energy used is supplied by anaerobic pathways and consequently,
any decrease in work capacity during the test will
be directly related to depletion of the anaerobic substrates,
accumulation of metabolite waste due both to insufficient
removal and exacerbated production, and diminished alkaline
reserves
