Relación de la fuerza muscular y el rendimiento en ejercicios de halterofilia y gimnásticos en practicantes amateur de CrossFit®

Abstract

The study focused on replicating and expanding the research conducted by Tibana et al. (2016). It analysed the relationship between strength in Back Squat, Front Squat, and Pull Up exercises and their influence on the performance of specific activities such as Snatch, Clean & Jerk, and Kipping Pull Up. Twenty-two subjects participated in the study, who were divided into two groups based on their performance in the Snatch and Clean & Jerk exercises: high strength group (age, 33.36 ± 6.31 years; body mass, 84.50 ± 10.36 kg; and height, 1.77 ± 0.03 cm) and low strength group (age, 35.35 ± 10.29 years; body mass, 70.97 ± 16.81 kg; and height, 1.73 ± 0.13 cm). All subjects performed a 1 repetition maximum (1RM) test of Back Squat, Front Squat, Pull Up, Snatch, and Clean & Jerk and the maximum repetitions test of Kipping Pull Up. Significant differences (p≤0.05) were observed between the groups in body mass, body mass index, practice time, and training hours. In addition, significant differences (p≤0.05) were detected in the maximum repetitions of all the exercises performed, with the exception of the Kipping Pull Up (p>0.05). Correlations (p≤0.01) were found between most of the values achieved in the different exercises. However, the Kipping Pull Up exercise was only related to the results found in the Pull Up (p<0.05). Participants with higher strength values in Back Squat, Front Squat, and Pull Up showed better performance in Snatch, Clean & Jerk, and Kipping Pull Up
