High-Intensity Interval Training (HIIT) and Medium-Intensity Interval Training (MIIT) are popular training methods known for enhancing athletic performance. HIIT is characterized by short bursts of high-intensity exercise followed by brief recovery periods. This training approach typically involves exercising at 80-95% of maximum heart rate for intervals ranging from 20 seconds to a few minutes, followed by rest or lower-intensity activity. Moderate-Interval Training (MIIT), on the other hand, involves moderate-intensity exercise performed at 60-75% of maximum heart rate. The primary objective is to determine how HIIT and MIIT differ in improving CPF, strength, and agility among athletes. A randomized clinical trial will be conducted with a sample size of 80 athletes, divided into two groups. Participants will undergo 45-minute training sessions three times a week for six weeks, followed by pre- and post-intervention assessments using Cooper's 12-Minute Run/Walk Test, T-Test for agility, and Active Force 2 muscle tester for strength. Statistical analyses will be conducted to compare pre- and post-intervention results between the two groups, determining the significance of differences in CRF fitness, strength and agility outcomes.

This phase II trial tests whether taking ulipristal acetate prior to a mammogram decreases breast density for people with a history of extremely dense breast tissue. One limitation to breast cancer screening with mammography is dense breast tissue, which decreases the sensitivity of screening as breast density masks cancer and precancerous lesions. Ulipristal acetate lowers the amount of progesterone made by the body which may temporarily decrease the density of the breast tissue, allowing for a more accurate mammogram for people with extremely dense breast tissue.
