This pilot study is needed prior to launching precision therapeutics programs, with the purpose to decrease the risk of research waste, increase the reliability of the experimental tests and estimate adequate sample size.~25 participants will be recruited to undergo three sets of experiments. An experiment consists of one exercise bout followed by an assessment of whole-body insulin sensitivity (measured from a oral glucose tolerance test) 1 and 2 days following the completion of the exercise bout yielding 19 study days of 3 hours each across 7 weeks, including the baseline measurement. The exercise modalities include 1) continuous aerobic exercise, 2) high intensity exercise and 3) resistance exercise training. A set consists of test-retest of the same experiment.~The objectives of this pilot study are~to assess the longevity of the increased whole-body insulin sensitivity in the days following different exercise modalities~To estimate the intra-individual differences of different exercise modalities on whole-body insulin sensitivity the days following the last exercise bout~To assess the fidelity of the test- and exercise protocols
The aim of this randomized cross-over study is to collect information for the design of a precision exercise therapy cohort that will predict what modality of physical activity a physically inactive individual with overweight should perform to increase insulin sensitivity given their unique biology, environment, and context.
