INTRODUCCIÓN: A lower capacity to oxidize fat is associated with a higher risk of diseases such as obesity, type 2 diabetes mellitus, cardiovascular disease, and metabolic syndrome, among others. Maximal Fat Oxidation during exercise (MFO) is considered a marker of metabolic health. The time and quality of sleep could be directly related to MFO. OBJETIVOS: The aim of the present study was to investigate the relationship of sleep quality and time with maximal fat oxidation during exercise in healthy young adults. METODOLOGÍA: Seventy-one adults (n = 26 women; 22.72 ± 4.40 Years) participated in this cross-sectional study. Body composition, cardiorespiratory fitness (VO2max), maximal fat oxidation (MFO) and sleep quality measurements were taken. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). MFO was determined through indirect calorimetry by a cycle ergometer graded exercise test and was relativized by total lean mass (mg/kg). RESULTADOS: PSQI global score was directly associated with lower maximal fat oxidation (MFO) (p=0.002), Both expressed in mg/kg/min, independently of confounders. Only components 2 (p=0.005) And 3 (p=0.009) Of the PSQI (sleep latency and sleep time, respectively) were associated with MFO. CONCLUSIÓN: In conclusion, our study showed that subjective poor sleep quality was associated with lower MFO, possibly being “latency sleep” and “time sleep” the most important components of sleep quality.
