*
Significant differences within groups from PRE (Baseline) to POST training intervention (p ≤ 0.05). MET=Metabolic Equivalent of Task. VO2 = maximal oxygen uptake; VE = maximal pulmonary ventilation; RER = maximal respiratory exchange ratio; HRmax = Maximal heart rate; PRE = baseline data; POST= post intervention data *Significant differences within groups from PRE to POST training intervention (p ≤ 0.05).
