Characteristics of the study participants.

Age (years)	41.69 ± 4.64
Sex	Male
Height (m)	1.78 ± 0.06
Body mass (Kg)	73.13 ± 7.87
Body mass index (kg/m2)	23.04 ± 1.46
VO2max (ml/kg/min)*	57.34 ± 3.12
TMHR (bpm)#	178.81 ± 3.31

^*VO2max was calculated with the equation: VO2max = (22.351 × kilometers) − 11.288 (57), where “kilimeters” represent the distance covered by the athletes in the 12-min bout at maximum intensity on the treadmill.

^# TMHR (Theoretical maximum heart rate) of the subjects was calculated with the equation: HRmax = 208 − (0.7 × age) (58–60). Data were presented as mean ± standard deviation.
