Biomechanics and Medicine in Swimming XI

Table 5. Mean±standard deviation values (X±SD) of the total swimming
time (t), mean duration of each cycle (tcycle), stroke frequency
(SF), cycle mean force (FmeanC) and variation coefficient of FmeanC
(VC). Values for time intervals defined by the fatigue thresholds of postpubertal
swimmers.
