Vertical and horizontal groups additionally performed back-half-squat or barbell hip-thrust, respectively. Control group performed a general strength training program (free weights, eccentric-overload, and body mass exercises) once a week during 20 weeks.

Twenty-four well-trained male under-17 players participated in this study and were randomly assigned to a control, vertical, or horizontal training group. This study aimed to explore the effects of adding vertical or horizontal force-vector exercises to a 20-week in-season general strength training program on jumping and sprinting performance of youth football players. Thus, training routines must consider the direction of force application, particularly when strength exercises are performed. J Strength Cond Res 35(10): 2769-2774, 2021-Football is characterized by short-term high-intensity triaxial activities that require optimized neuromuscular capacity. Effects of adding vertical or horizontal force-vector exercises to in-season general strength training on jumping and sprinting performance of youth football players.
