Peak work rate: work rate achieved at exhaustion; Peak VO2: rate of oxygen uptake at exhaustion; Peak HR: heart rate at exhaustion; : rate of oxygen uptake at steady state level; Work ratess: work rate at steady state level; VO2 at GET: rate of oxygen uptake at the gas exchange threshold; /VO2 at GET: ratio of oxygen uptake at steady state level to oxygen uptake at the gas exchange threshold; HRss: heart rate at steady state level.
