简要总结
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.

研究组 & 干预措施
Control
A chocolate milkshake with a normal calcium content will be consumed daily (235 kcal; 13 g protein; 42 g carbohydrate; 1 g fat, 400 mg calcium per serving).
干预措施: Placebo (Dietary Supplement)
High-Calcium
A chocolate milkshake with a high calcium content will be consumed daily (235 kcal; 13 g protein; 42 g carbohydrate; 1 g fat, 1400 mg calcium per serving).
干预措施: Calcium (Dietary Supplement)
结局指标
主要结局
Substrate metabolism
时间窗: 60 s samples every 3 min for 15 min
Substrate metabolism will be assessed by the respiratory exchange ratio (rate of carbon dioxide production/rate of oxygen consumption) from samples of expired gas collected during the first 15 minutes of an incremental cycling test.
次要结局
- Plasma non-esterified fatty acid concentrations(Every 3 min for 15 min)
- Plasma glycerol concentrations(Every 3 min for 15 min)
