The purpose of the present research was to determine the optimal load which produces maximum power in exercises squat, deadlift, hip thrust, Romanian deadlift and high pull. 19 male and 8 female football and track and field athletes participated in the survey. In the first session, the anthropometric characteristics of the athletes were assessed. In the next 3 sessions, the evaluation of the 1 repetition maximum (RM) in the previous exercises was carried out. Then, in the next 3 sessions, the athletes performed power measurements at 20, 35, 50, 65 and 80% of their individual 1 repetition maximum (RM) in the previous exercises, in random order. The optimal load in the squat exercise was at 57.47 ± 5.44% of the 1RM, in the exercise of deadlift at 54.12 ± 6.87% of the 1RM, in the hip thrust exercise at 57.21 ± 7.44% of the 1RM, in the exercise of Romanian deadlift at 60.78 ± 6.5% of the 1RM and in the high pull exercise at 59.16 ± 7.62% of the 1RM. The relative mechanical power in terms of body weight and lean body mass of the athletes was evaluated without any significant differences. Fitness coaches can use research results to design muscle power programs more efficiently in athletes in velocity - force based sports.
