Procedure for data analysis. Each parameter was analyzed every 30 s. Muscle phosphocreatine (PCr), inorganic phosphate (Pi), pH, estimated ADP and free energy of ATP hydrolysis (ΔG_ATP), pulmonary oxygen uptake (o_2pul), and electromyogram (EMG) were averaged over 30 s. The data for muscle oxygen consumption (o_2mus) were obtained during the third (20–26 s) and sixth (50–56 s) contractions at each intensity. The o_2musvalue of the third contraction was used to represent the first 30 s of each minute, whereas the o_2musvalue of the sixth contraction was used to represent the last 30 s of each minute. Division of data analysis (30s). o_2musmeasurement (6 s; once per three contraction phases).
