Effect of the CMT and HIIT protocols on physical performance. Changes in blood lactate levels (mmol l⁻¹) after one-time exhaustive exercise (a), time to exhaustion (min) (b), and grip strength (N g⁻¹) (c). Groups: SC sedentary control; CMT continuous moderate-intensity training, HIIT high-intensity interval training. Data are presented as mean ± SD (n = 8). ^aP < 0.05 versus SC; ^bP < 0.01 versus SC; ^cP < 0.05 versus CMT
