Popis:	To determine the roles of calcium (CaContractile performance was assessed during 3 min of repeated MVCs (7-s contraction, 3-s rest, n = 17). In ten participants, in vitro SR CaThe decline of peak MVC force with fatigue was similar for both muscles. Fatigue resistance correlated directly with % type I fibre area in quadriceps (r = 0.77, P = 0.009). The maximal rate of ryanodine-induced CaFatigue with repeated MVC in human limb muscles mainly involves peripheral aspects which include impaired SR Ca
