Resistance Training and Sex Hormones During Menstrual Cycle

Resistance Training and Sex Hormone Concentrations During the Menstrual Cycle

Although there are numerous studies showing effects of aerobic training on sex hormone concentrations, research analyzing the fluctuation of sex hormones in response to resistance training (RT) is lacking. The objective of this project is to analyze estradiol (E2) and progesterone (P4) responses to an acute resistance training session throughout different phases of the menstrual cycle. This proposed research has strong implications for exercise prescription and for women in general, but more importantly will allow exercise physiologists, coaches, personal trainers, or nutritionists optimize exercise programming around women's menstrual cycle.

Behavioral - Resistance Training

Participants will exercise at the mid-point of each menstrual cycle phase (EFP- day 4, LFP- day 11, ELP- day 18 and LLP- day 25 for a 28 day menstrual cycle). Training will consist of a warm up. Intensity will be set at 70% of 1RM, and the circuit training will include 7 strength exercises: leg press, rows, back squat, weighted crunches, deadlifts, bench press, and weighted squat jumps. The participant will perform 3 sets f 10 repetitions with 30 seconds of rest
