Note: Values are mean ± standard deviation. Abbreviations: PEMF: pulsed electromagnetic field; CON: control; MD: Mean difference; CI: confidence interval; AbsVO_2Peak: absolute VO_2Peak; RelVO_2Peak: relative VO_2Peak; VE: ventilation; VT_Abs: absolute ventilatory threshold; VT_Rel: relative ventilatory threshold; HR_Max: maximum heart rate; HR_VT: heart rate @ ventilatory threshold; RR_Max: maximum respiration rate; RR_VT: respiration rate @ ventilatory threshold. * indicates significantly different, compared to pre (p < 0.05). ^ indicates trending toward significant, compared to pre (0.05 < p < 0.10).
