Ca(2+)-pumping impairment during repetitive fatiguing contractions in single myofibers: role of cross-bridge cycling
The energy cost of contractions in skeletal muscle involves activation of both actomyosin and sarcoplasmic reticulum (SR) Ca(2+)-pump (SERCA) ATPases, which together determine the overall ATP demand. During repetitive contractions leading to fatigue, the relaxation rate and Ca(2+) pumping become slo...
