Maximal oxygen uptake and post-exercise recovery in professional road cyclists
Journal Title: Human Movement - Year 2016, Vol 17, Issue 3
Abstract
Purpose. The aim was to investigate the relationship between aerobic fitness as ascribed by maximum oxygen uptake (VO2max) and post-exercise recovery after incremental exercise to volitional exhaustion. Methods. A sample of 17 professional cyclists (age 17.4 ± 3.1 years; VO2max 61.1 ± 7.2 ml/min/kg) were recruited. A graded exercise test was administered on a cycle ergometer. Upon termination, the participants remained seated, and oxygen uptake (VO2), minute ventilation (VE), and heart rate (HR) were measured in the 1st, 3rd, and 5th minute of recovery. Results. Post-exercise VO2 dynamics revealed a 69% and 80.9% reduction from VO2max in the 1st and 5th minute, respectively. HR decreased only by 41% of HRmax, in the 5th minute of recovery. A positive correlation between the differential rate of recovery for VO2 and VO2max indicated a dependency between aerobic fitness and recovery potential. Correlative strength decreased with time, and by the 5th minute of recovery a significant correlation was evidenced only between VO2 and VE. Conclusions. As recovery potential is associated with the aerobic fitness level, training effects may be monitored based on the recovery of VO2 and HR to pre-exercise values. Key words: physical capacity, maximum oxygen uptake, post-exercise recovery, road cyclists
