The Impact of 12-week Ashwagandha Supplementation Induced by Resistance Training on Strength, Levels of Neurotrophic and Stress Response Proteins, Oxidative and Psychological Stress, and Cognitive Function in Physically Active Male Adults

Conditions: Strength Training Adaptations, Stress, Sleep Quality, Cognitive Functions, Oxidative Stress, Inflammation

Location: Gdansk University of Physical Education and Sport Gdansk Pomeranian Voivodeship

Summary

This clinical trial will study the effects of Ashwagandha (Withania somnifera), a natural plant extract, on physical and mental health in adult men. Ashwagandha is known for its potential to reduce stress, support hormonal balance and improve sleep and physical performance. The study will explore how taking Ashwagandha for 12 weeks, with resistance training, affects various health markers such as stress hormones, brain function, muscle strength, body composition, sleep quality, and cognitive abilities. Participants will be healthy, non-smoking men aged 25-40, with regular resistance training experience. They will be randomly assigned to one of two groups: (1) weight training + Ashwagandha, (2) weight training + placebo. The study is double-blinded, meaning neither participants nor researchers will know who is receiving Ashwagandha or placebo. Participants will: * Take Ashwagandha or a placebo every day for 12 weeks * Train in the gym three times a week Researchers will assess changes in blood markers (like cortisol, testosterone and BDNF - brain-derived neurotrophic factor), physical performance (muscle strength and endurance), sleep quality, stress perception and cognitive function before and after the 12-week period. The goal is to better understand how Ashwagandha works.

Eligibility Criteria
