Validation of a Fatmax Protocol

27 February 2017

A high capacity to burn fat during exercise is desirable to both athletes and the general population. The current study looks to develop an exercise protocol to accurately measure fat use during exercise, so we can better understand factors influencing maximum fat use during exercise. We hope this will help develop strategies to optimize exercise and nutrition for health.

The study requires five visits (between 20-60 minutes) to the University of Bath and is outlined in greater detail below.


  • Male or Female
  • Age 18 - 65 years
  • Body mass index between 25 and 35 kg/m2
  • Non-active
  • Partake in less than 1-hour of exercise per week
  • No current or previous metabolic, cardio-pulmonary or musculoskeletal disease
  • Willing to refrain from alcohol and physical activity that substantially increases your breathing rate for the prior 24-hours to each exercise visit
  • Maintain habitual lifestyle (physical activity and diet) for the duration of the study period (max. 14-days)
