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

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 (V̇O2max) levels (P<0.001). 59.3% of the SRG had excellent V̇O2max. 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 V̇O2max 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 V̇O2max although they train less than the CF practitioners regardless of factors such as BF%, gender and age.

CAT correlates positively with respiratory rate and is a significant predictor of the impact of COPD on daily life of patients: a cross sectional study.

BACKGROUND: The pathophysiological changes of COPD tend to worsen with progression, triggering limiting symptoms and implying the decrease in the activities of daily living and quality of life. The COPD Assessment Test (CAT) is a questionnaire designed to measure the impact of COPD on the health status. The aim of this study was to evaluate the impact of the disease through the CAT in a Brazilian sample of COPD patients and to correlate symptoms at rest with the CAT score in these patients. METHODS: Study of cases with COPD patients was conducted by pulmonary rehabilitation program (RP). Respiratory rate (RR) and symptoms (dyspnea by Modified Borg Scale Dyspnea Index; symptoms by CAT) were analyzed at the beginning of the RP. RESULTS: The study analyzed 28 COPD patients, both genders, age 65.93 ± 7.84 years and many patients ranging from severe and very severe disease. The majority of patients were rated by CAT with low impact-disease (n = 13/46, 4%);medium (n = 11/39, 3%) and the high impact-diseases were observed in a few subjects (n = 4/14.3%). The difference between all CAT scores was significant, p = 0.000. There was a positive correlation between respiratory rate and CAT scores impact-level (r = 0.585, p = 0.001). The results obtained by the Borg Scale revealed a high presence of symptoms in these COPD patients but no association with CAT. CONCLUSION: The CAT is a sensitive tool to assess the current health status of COPD patients, and in Southern Brazil it is positively correlated with respiratory rate.
