Research Overview

A recent undergraduate research study from St. Olaf College has drawn attention in Women’s Health. Conducted by Lauren Hall ’27 and overseen by Assistant Professor of Kinesiology Jenny Miller, this investigation was published in the Journal of the International Society of Sports Nutrition.

Study Details

The study focused on the effects of creatine supplementation among women experiencing perimenopause and post-menopause. Specifically, the research team analyzed the impact of a daily intake of five grams of creatine combined with a resistance training regimen performed twice a week over a span of 14 weeks. The study involved 15 participants.

The findings indicated significant positive outcomes, particularly in the areas of:

• Muscle Strength: Notable improvements were observed, especially in lower body strength.
• Body Composition: Participants experienced enhanced body composition.
• Sleep Quality: Better sleep patterns were reported.
• Cognitive Function: One-third of the postmenopausal participants showed improvement, transitioning from mild cognitive impairment to normal cognitive function.

Significance of Findings

In her remarks to Women’s Health, Hall noted that while creatine is well-known for enhancing muscular strength and athletic performance, the benefits relating to sleep and cognitive improvements, particularly in postmenopausal women, were particularly encouraging. She stated, “While creatine is well-established for its role in muscular strength and performance, the positive changes in perceived sleep and cognition, especially among postmenopausal participants, were encouraging.”

Potential Mechanisms

Hall elaborated on the mechanisms behind these benefits, suggesting that creatine may play a role in supporting brain energy metabolism and offering neuroprotection. These effects could help in stabilizing sleep and enhancing cognitive resilience amid hormonal transitions.
