This randomized controlled trial published in the Journal of Strength and Conditioning Research explores the effects of complex training using two different exercise sequences: ascending (CAT) and descending (CDT). The study involved 25 male university athletes who were randomly assigned to either the CAT group, which performed ballistic exercises before resistance exercises, or the CDT group, which performed resistance exercises before ballistic exercises.
The athletes underwent a six-week training program, and their physical performance was assessed before and after the intervention. The performance measures included countermovement jump (CMJ), squat jump (SJ), rebound jump, isometric midthigh pull, isometric squat, 1 repetition maximum squat, linear sprint (10, 20, 30 m), change-of-direction speed, standing long jump, and Yo-Yo intermittent recovery level 1.
The main findings indicated that both training sequences led to significant improvements in various physical performance measures over time. Specifically, the study noted enhancements in CMJ and SJ performance, including jump height, peak power, and other related metrics. Additionally, improvements were observed in isometric strength, linear sprint times, change-of-direction speed, and intermittent endurance.
However, the analysis revealed that while there was a time × group interaction effect for the 1 repetition maximum squat, showing a significant difference favoring the CDT group, no other between-group differences were found for the other outcome variables. This suggests that both training methods were equally effective in enhancing overall physical fitness measures.
In conclusion, practitioners working with male university athletes can choose either the ascending or descending exercise sequence based on their specific training goals and logistical considerations. Both methods were shown to be effective in improving various aspects of physical performance.
