Dataset for "Biological sex and aerobic capacity are key determinants of peak fat oxidation rates during exercise"

The aims of this study was to explore biological and lifestyle factors that independently associated with peak fat oxidation rates (PFO) in a diverse cohort of healthy men and women. This study was a cross-sectional study that recruited n = 115 adults (aged 18 – 65 years) who had varying levels of cardiorespiratory fitness, habitual physical activity levels and body composition. Participants completed three trials (Trial A, Trial B and Trial C) alongside the assessment of habitual physical activity levels (via a chest worn monitor) and dietary intake (self-reported diet diary). Trial A and Trial B followed identical protocols (completed 7 - 28 days apart) that involved anthropometric measurements, resting metabolic rate, a resting venous blood sample and the completion of a graded exercise test to determine PFO and FATMAX by indirect calorimetry. At Trial C (2 - 7 days after Trial B) body composition was assessed (via a dual energy x-ray absorptiometry scan) and optional adipose tissue and/or skeletal muscle biopsies were obtained. All trials were completed in an overnight fasted-state.

The dataset includes demographic data of the participants (n=115) and data from the three trials they participated in. The types of data that were collected during the trials are as follows: Trial A and Trial B followed identical protocols that involved anthropometric measurements, resting metabolic rate, a resting venous blood sample (to look at various plasma metabolite and hormone concentrations) and the completion of a graded exercise test to determine PFO and FATMAX by indirect calorimetry; at Trial C, body composition was assessed (via a dual energy x-ray absorptiometry scan) and optional adipose tissue and/or skeletal muscle biopsies were obtained (Biopsy data not included). All trials were completed in an overnight fasted-state.
