| Abstract (English): | Objectives: The aim of the present study was to analyze and correlate muscle strength of the back and front squat with performance in the movements of weightlifting snatch and the clean in CrossFit® practitioners. Method: Twenty-two adults participated in this study and were divided according to their performance in the snatch and clean movements: stronger (29.6 ± 4.4 years; 80.95 ± 9.57 kg; 12.2 ± 5.8% body fat; 2.4 ± 0.9 training experience) and weaker (28.5 ± 5.4 years; 79.4 ± 6.8 kg; 13.6 ± 3.5% body fat; 2.0 ± 1.1 training experience). All volunteers completed one-repetition maximum tests, in separate days, in the following exercises: back squat, front squat, snatch and the first phase of the clean. Results: The volunteers classified with a superior performance in the snatch and clean presented a higher strength in the back squat (154.9 ± 20.3 kg vs 132.7 ± 11.6 kg; p = 0.009) and front squat (139.0 ± 14.5 kg vs 116.8 ± 11.3 kg; p = 0.002) as compared with the weaker volunteers. Additionally, there were strong correlations between relative strength in the back squat (r = 0.83; r = 0.76; p = 0.001) and front squat (r = 0.73; r = 0.83; p = 0.001) with the performance in the snatch and clean exercises, respectively. Conclusions: Therefore, a superior strength in basic exercises, such as back and front squat can contribute to weightlifting performance in CrossFit® practitioners. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): | Objetivo: El propósito del presente estudio fue analizar y relacionar la fuerza muscular de la sentadilla por delante y por detrás con el rendimiento en los movimientos de halterofilia de arranque y de cargada en practicantes de CrossFit®. Método: Participaron en este estudio 22 adultos que fueron divididos de acuerdo con el rendimiento en los movimientos de arranque y cargada: fuertes (29.6 ± 4.4 años; 80.95 ± 9.57 kg; 12.2 ± 5.8% de grasa corporal; 2.4 ± 0.9 experiencia de entrenamiento) y débiles (28.5 ± 5.4 años; 79.4 ± 6.8 kg; 13.6 ± 3.5% de grasa corporal; 2.0 ± 1.1 experiencia de entrenamiento). Todos los voluntarios realizaron, en días diferentes, los test de una repetición máxima en los ejercicios: sentadilla por detrás, sentadilla por delante, arranque y cargada. Resultados: Los voluntarios clasificados con el mejor rendimiento en el arranque y en la cargada presentaron mayor fuerza en la sentadilla por detrás (154.9 ± 20.3 kg vs. 132.7 ± 11.6 kg; p = 0.009) y en la sentadilla por delante (139.0 ± 14.5 kg vs. 116.8 ± 11.3 kg; p = 0.002) cuando fueron comparados con los voluntarios más débiles. Además, se observaron correlaciones fuertes entre la fuerza relativa de la sentadilla por detrás (r = 0.83; r = 0.76; p = 0.001) y la sentadilla por delante (r = 0.73; r = 0.83; p = 0.001) con el rendimiento en los ejercicios de arranque y cargada, respectivamente. Conclusión: Por tanto, una mayor fuerza en ejercicios básicos, como la sentadilla por detrás y por delante, pueden contribuir para el rendimiento de los ejercicios olímpicos en practicantes de CrossFit®.
