The objective of this research study is two-fold, 1) to determine if body composition and body image perception are affected through the different phases of the menstrual cycle, and 2) if an acute session of resistance training can have different effects depending on the menstrual cycle phase.
The purpose of the research is to establish whether body composition and body image perception are affected throughout the different phases of the menstrual cycle and if the perception can be modified through resistance training. To the best of our knowledge, only one study has analyzed the effects of the menstrual cycle on body image perception. However, research analyzing the effects of the menstrual cycle on both body image perception and, body composition is lacking. Furthermore, research in the effects of resistance training on menstrual cycle-related changes on both perceived and measured body composition are inexistent. Findings from this study have the potential to increase the knowledge about resistance training's effects in modulating body image perception throughout the menstrual cycle. Further understanding of these responses may set the groundwork to develop exercise intervention programs to reduce the risk of developing more serious mental conditions linked to unhealthy body image perception.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Early Follicular Phase (EFP) | Experimental | The group will engage in the Resistance Training intervention on the fourth day of their menstrual cycle, which will correlate with the middle of the early follicular phase (EFP). |
|
| Late Follicular Phase (LFP) | Experimental | The group will engage in the Resistance Training intervention on the eleventh day of their menstrual cycle, which will correlate with the middle of the late follicular phase (LFP). |
|
| Early Luteal Phase (ELP) | Experimental | The group will engage in the Resistance Training intervention on the eighteenth of their menstrual cycle, which will correlate with the middle of the early luteal phase (ELP). |
|
| Late Luteal Phase (LLP) | Experimental | The group will engage in the Resistance Training intervention on the twenty-fifth day of their menstrual cycle, which will correlate with the middle of the late luteal phase (LLP). |

| EFP | Behavioral | This intervention will take place on day 4 of the participants' menstrual cycle. This will correspond to the mid-point of the early follicular phase (EFP). |
|
| Measure | Description | Time Frame |
|---|---|---|
| Body Image Perception through questionnaire | Participants will be distributed the Multidimensional Body-Self Relations Questionnaire-Appearance Scale (MBSRQ-AS) to measure their body image perceptions. | Through study completion: an average of 1 month |
| Body Image Perception through drawing scale | Participants will be distributed the Contour Drawing Rating Scale to measure their body image perception. | Through study completion: an average of 1 month |
| Barriers to Weight Control | Participants will be distributed the Survey of Barriers to Weight Control to measure their body image perception. | Through study completion: an average of 1 month |
| Fat Mass in Kilograms | We will measure fat mass using the Dual-Energy Xray Absorptiometry (DXA) | Through study completion: an average of 1 month |
| Lean Body Mass in Kilograms | We will measure lean body mass using the Dual-Energy Xray Absorptiometry (DXA) | Through study completion: an average of 1 month |
| Relative Body Fat | We will measure relative body fat (percentage) using the Dual-Energy Xray Absorptiometry (DXA) | Through study completion: an average of 1 month |
| Measure | Description | Time Frame |
|---|---|---|
| Bench Press One Repetition Maximum | Participants muscular strength will be assessed by a one-repetition (1RM) on bench press | At baseline: 1 assessment point prior randomization |
| Leg Press One Repetition Maximum |
