Influência da potência muscular na performance de corrida de 5km em corredoras recreacionais da cidade de João Pessoa/PB

Abstract

This observational study with a cross-sectional design aimed to investigate the relationship between lower limb muscle power and performance in a 5 km time trial among recreational runners in the city of João Pessoa/PB. The sample consisted of 21 women, with an average age of 31.4 ± 7.1 years and an average practice time in the sport of 30.3 ± 27.3 months. The countermovement vertical jump test (CMVJ) was applied, measured with the My Jump 2 application, and a 5 km time trial running test was conducted on the athletics track at the Federal University of Paraíba. The results showed no significant correlation between muscle power and time trial completion time (r = 0.243; p = 0.288). However, significant correlations were found between practice time and running performance (r = -0.609; p < 0.05), as well as between age and completion time (r = -0.565; p < 0.05). These findings indicate that experience and factors related to practice time may play a significant role in performance, reinforcing the importance of investigations that consider these variables in the context of recreational runners' training. It is concluded that muscular power is not a determining factor in running performance. The variables that showed influence on performance in the modality were practice time and age, suggesting that these factors may affect the performance of recreational runners
