Summary

This research project's objective is to investigate substrate metabolism behavior in response to the RT during different phases of the menstrual cycle.

Detailed description

Based on the literature the investigators hypothesize an increase in fat oxidation in early follicular phase(EFP) and late follicular phase (LFP) when compared to early luteal phase (ELP) and late luteal phase (LLP). Given the lack of research in exercise and menstrual cycle - especially in resistance training - results are uncertain unless the investigators base their hypotheses only on the general physiological effects of sex hormones (without exercise). In this case, the investigators expect to see a reduced carbohydrate utilization and an increased utilization of fats in EFP and LFP. In addition, the intervention is focused on muscular endurance and, therefore, it is expected to see a higher reliance on aerobic pathways. It is expected that the effects of the intervention will be added to the effects of estrogens, with increasing fat oxidation when estrogen levels are higher. Lastly, a comparison of fat oxidation levels obtained on each sub-phase would reveal if there are differences in the magnitude of the effect of distinct concentrations of estrogen and progesterone.

Conditions

• Menstrual Cycle
• Substrate Metabolism

Interventions

Type	Name	Description
BEHAVIORAL	EFP	This group will perform the Resistance training intervention on day 4 of the menstrual cycle, which corresponds to the mid of early follicular phase.
BEHAVIORAL	LFP	This group will perform the Resistance training intervention on day 11 of the menstrual cycle, which corresponds to the mid of late follicular phase.
BEHAVIORAL	ELP	This group will perform the Resistance training intervention on the day 18 of the menstrual cycle, which corresponds to the mid of early luteal phase
BEHAVIORAL	LLP	This group will perform the Resistance training intervention on day 21 of the menstrual cycle, which corresponds to the mid of late luteal phase
