Figure 2. Relationships between the time constant of the fast component of the recovery period (toff) and the mean swimming speed of the 200-m (200speed - full line: y =1.284x + 0.002, n = 8, r = 0.77, p < 0.05), between toff and peak oxygen uptake (VO2peak - dotted line: y = 46.975x + 0.305, n = 8, r = 0.76, p < 0.05) and between toff and the amplitude of the fast component of the effort period (Aon - grey line: y= 32.594x + 0.192, n = 8, r = 0.72, p < 0.05).
