* p < 0.05 compared with Light Weight Category

# p < 0.05 compared with medium Weight RHR= resting heart rate, MHR= maximal heart rate, HRR1 = heart rate during 1st min recovery, HRR2 = heart rate during 2nd min recovery, HRR3 = heart rate during 3rd min recovery, VO= maximal oxygen uptake, RL = resting lactate concentration, PL = peak lactate concentration. Light Weight Category <54kg, Medium Weight Category 55-64 kg, Medium heavy Weight Category 65-75 kg.
