Abstract
This study investigated the effects of different 8-week concurrent training sequences on the maximal strength and explosive power of lower extremities in male college students. Forty male students from sports colleges were divided into four groups, following the same training content and load over an 8-week period and prioritizing different types of training: resistance-training (GCOM1 RT + ET), endurance-training (GCOM1 ET + RT), two-session resistance-training (GCOM2 RT + ET), and two-session endurance-training (GCOM2 ET + RT) priority groups. The one-repetition maximum (1RM) deep squat score improved significantly after different training sequences (F = 12.240, p < 0.001, ES = 0.238). Post hoc two-by-two comparisons showed that the effect size was significantly lower in the GCOM1 RT + ET (p < 0.05), GCOM2 RT + ET (p < 0.05), and GCOM2 ET + RT (p < 0.05) groups. The 1RM hard pull improved significantly after different training sequences (F = 3.674, p = 0.021, ES = 0.234). Post hoc two-by-two comparisons showed that the degree of variables was significantly lower in the endurance-first group than in the two-session strength-first group (p < 0.05) and the two-session endurance-first group (p < 0.05). Squat jumps improved significantly after different training sequences (F = 12.405, p < 0.001, ES = 0.508). Post hoc two-by-two comparisons showed that the degree of variables was significantly higher in the strength-first exercise group during the same session than in the endurance-first exercise group during the same session (p < 0.05), two-session strength-first exercise group (p < 0.05), and two-session endurance-first exercise group (p < 0.05). Squat jumps improved after different training sequences without significant differences (F = 0.495, p = 0.688, ES = 0.004). The GCOM2 training sequence was more effective than the GCOM1 sequence in improving the maximum strength of the lower limbs. The RT + ET training sequence was more effective in improving the countermovement jump height using the GCOM1 training sequence. Future research should consider factors such as training pattern and intensity.
