dc.description.abstractThe purpose of this study was to examine the relationship between VO2 max, maximal cardiac output (Q) and arterial venous oxygen difference (a­vO2), and the recovery from maximal intensity intermittent anaerobic exercise. Twenty male university level rugby (n=16) and soccer (n=4) players volunteered for the study. Mean (standard deviation) age, mass and VO2 max was 21.9 (1.8) years, 84.7 (12.7) kg and 52.7 (6.9) mL•kg-1•min-1 respectively. The exercise protocols, separated by 36-48 hours, consisted of six 15s (90s active recovery) and ten 6s (30s active recovery) maximal intensity sprints on a Monarch friction braked cycle ergometer. In the 6 x 15s protocol, significant relationships were obtained between VO2 max (mL•kg-1 •min-1) and percent drop-off in mean power in bouts 5 and 6 compared to bout 1 (MPDO155,6) and bout 6 compared to bout 1 (MPDO156) of r = -.49 (p = 0.03) and r = -.63 (p = 0.004) respectively. Correlations of r = -.62 (p = 0.002) and r = -.63 (p = 0.002) were obtained between VO2 max (mL•kg-1•min-1) and percent drop-off in peak power in bouts 5 and 6 compared to bout 1 (PPDO155,6) and percent drop-off in bout 6 compared to bout 1 (PPDO156). Percent drop-off in mean power during bouts 8, 9 and 10 compared to bout 1 of the 10 x 6s protocol (MPDO68,9,10) demonstrated a weaker relationship with VO2 max (r = -.2, p = 0.4). Significant correlations were obtained between a-vO2 and MPDOlS5,6 (r = -.54, p = 0.02) and MPDO156 (r = -.57, p = 0.01). Percent oxygen consumption, when compared to the first, in the second (VO230-60), third (VO260-90), fourth (VO290-120) and fifth (VO2120-150) 30s time period of recovery following the two protocols was also calculated. Correlations between VO2 max (mL •kg-1• min-1) and VO230-60 (r = .51, p = 0.03), VO260-90 (r = .44, p = 0.06), VO290-120 (r = .42, p = 0.08) and VO2120-150 (r = .47, p = 0.04) as well as between a-vO2 and VO230-60 (r = .38, p = 0.11), VO260-90 (r = .49, p = 0.03), VO290-120 (r = .64, p = 0.003) and VO2120-150 (r = .6, p = 0.007) were also obtained. The results suggest that maximal aerobic power, particularly the peripheral component, is an important determinate of the ability to recover from maximal anaerobic exercise and that an elevated creatine phosphate resynthesis rate is at least partly responsible.
