Relação da economia de corrida com o consumo máximo de oxigênio, a força muscular máxima e a força explosiva de corredores

Abstract

The objective of this study to investigate the relationship between Running Economy (EC) with Maximum Oxygen Consumption (VO2máx), Maximum Muscle Strength, and Explosive Strength of lower limbs in runners. Fourteen male subjects with a mean age of 24.86 ± 5.16 years, body mass of 72.55 ± 9.34kg, height of 1.70 ± 0.08 cm and 9.82 ± 2.64 % body fat, runners for at least a year. The subjects attended the Biomechanics Laboratory twice with an interval of four days. On the first day, the samples were characterized by anthropometric parameters, after which the test battery was started, in which the participants performed the Explosive Strength, Maximum Muscle Strength, RE and VO2máx tests in that order. On the second day of evaluation, the subjects underwent an exercise stress test to estimate the Maximum Oxygen Consumption. Mean and standard deviation values were calculated and Pearson's correlation test was used to analyze the relationships between the variables. In all tests, a significance level of p<0.05 was adopted. As results found, VO2máx measured by the ventilometer had a high and significant correlation (r = 0.91; p<0.01) with the estimation protocol. RE was inversely related to VO2máx (r = -0.72; p <0.01), however, no significant correlation was found between RE and maximal strength (r = 0.46; p>0.05) and the explosive force (r = 0.36; p>0.05). In conclusion, RE has a strong relationship with maximal oxygen uptake, thus attributing that strategies aimed at improving one of these variables can positively influence the other. However, maximum force and explosive force do not appear to be associated with RE.
