Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A high-calcium intake can accelerate fat loss under energy-restricted diets. Part of this may be due to a shift in substrate metabolism where there is an increase in the rate of fat oxidation. However, whether high-calcium intake can influence substrate metabolism during exercise is not known. Accordingly, we aim to investigate the effect of 2 weeks of high-calcium intake on substrate metabolism during exercise.
