ANALYSIS OF RUNNING PERFORMANCE WITH AND WITHOUT ALCOHOL CONSUMPTION IN YOUNG MEN

Abstract

The objective of this study was to evaluate the influence of body fat percentage (%BF) and blood glucose and blood lactate concentrations on running performance in young adults, in contexts with and without alcohol consumption. This is a pre-experimental, cross-over study. The study included 12 male university students aged between 18 and 30 who underwent a physical test with or without alcohol consumption. The dependent variable in this study was running performance, expressed by the total distance covered in the intermittent recovery test (Yo-yo). %BF was estimated via skinfolds and lactate (mmol/L) and glucose (mg/dL) concentrations obtained via blood collection, using a portable lactimeter. Multiple linear regression was used to estimate determination. The significance level was 5%. In situations without (β: 71.453; 95%CI: 10.922; 131.985) and with (β: 76.657; 95%CI: 32.313; 121.002), increased lactate levels were associated with increased running performance. It is concluded that there was an increase in blood lactate levels, with or without alcohol consumption in acute and moderate doses, in performance in intermittent running. Furthermore, %BF and blood glucose levels were not determinants of performance, regardless of alcohol intake or not.
