SCG: serial combined group; ICG: integrated combined group; CG: control group; HR test: heart rate values during the submaximal exercise; HR_rec: 1-min recovery heart rate; RPE_test: rating of perceived exertion during the submaximal exercise; VO_2max estimation: was used the following equation: VO_2max = 15.1 + 21.8 (speed in mph) − 0.327 (heart rate in bpm) − 0.263 (speed × age in years) + 0.00504 (heart rate in bpm × age in years) + 5.98 (gender: female = 0, male = 1). * p < 0.001 pre-training vs. post-training and pre-training vs. training cessation in SCG and ICG, # p < 0.01 post-training vs. training cessation in SCG and ICG, † p < 0.01 vs. CG.
