Effects of Crossfit and street running practice on anthropometric, lipids parameters, cardiorespiratory fitness and sleep quality

Abstract

BacKGrouNd: Street running (Sr) and crossfit® (cf) have different characteristics ranging from aerobic training to high intensity. This study aimed to describe the subject’s physical training, anthropometric and lipid parameters, cardiorespiratory fitness and sleep quality and duration. MeThodS: cross-sectional, study, that collected personal data, pittsburgh Sleep Quality index (pSQi), anthropometric assessment, cardiorespiratory fitness, and lipid profile. The subjects were separated in CF group (CFG) and SR group (SRG). RESULTS: The SRG training frequency was lower (P=0.006), had better maximum oxygen consumption (V̇ o2max) levels (p<0.001). 59.3% of the SrG had excellent V̇ o2max. Cardiorespiratory fitness (49.97 mL/kg/min; P=0.001) and Body Mass Index (BMI) were positively related in SR (P=0.031). An inverse correlation was found between V̇ o2max and body fat percentage (BF%) (SRG: P=0.001; CFG: P=0.013). Sleep duration is strongly and inversely associated with PSQI. There was a correlation between total cholesterol (TC) and high-density lipoprotein cholesterol (P=0.020), TC and triglycerides (TGs) (P=0.029) and levels of TGs and BMI (P=0.008) in SRG. In the CFG group, there was a correlation of TC between TGs levels (P=0.025), light-density lipoprotein cholesterol (P<0.001) and BMI (P=0.050). coNcluSioNS: The Sr have a higher V̇ o2max although they train less than the cf practitioners regardless of factors such as Bf%, gender and age.
