The Impact of Omega-3 Fatty Acid Supplementation on the Composition of Erythrocyte Membranes in Athletes

The aim of this study is to evaluate the effects of omega-3 fatty acid supplementation on the Omega-3 Index, erythrocyte membrane composition, cognitive function, hormonal profile, speed, endurance performance, and hematological parameters in competitive athletes aged 16-35 years.

Whey Protein and Adaptogenic Supplementation in Physically Active Males

The goal of this clinical trial is to learn whether whey protein, with or without an adaptogenic herb blend, can improve strength, recovery, stress, and wellbeing in active males. The adaptogenic blend contains 600mg ashwagandha root extract.The main questions the study aims to answer are: Does whey protein improve muscle strength and recovery in physically active males? Does adding ashwagandha to whey protein further improve stress, recovery, sleep, and wellbeing compared with protein alone? Are there differences between whey protein when combined with the adaptogenic blend? Researchers will compare two supplement groups: * Whey protein * Whey protein with ashwagandha Participants will: * Take their assigned supplement for 6 weeks * Attend two testing sessions before and after the intervention * Complete questionnaires about recovery, sleep, stress, soreness, and digestive health * Provide saliva samples to measure stress, hormone, immune, and inflammation markers * Complete muscle strength tests, including handgrip strength and push-up testing * Complete a 24-hour dietary recall * The study includes physically active males aged 18 to 45 years who regularly participate in structured training.

Effect of a Short-term Multi-strain Probiotic Supplementation in Endurance Athletes

The aim of this project is to evaluate and identify the effect of a short-term 2-week multi-strain probiotic (MPRO) supplementation on the exercise-associated gastrointestinal (GI) symptoms and perturbations in high level female athletes of the Polish national team during strictly controlled conditions of a training camp, based on recommendations for best practices for probiotic (PRO) research in athletes and assessment of EX-associated GI perturbations.

Pre-Sleep Creatine Enhances Anaerobic Power in Recreationally Active Females

This study is a randomized, double-blind, placebo-controlled trial designed to examine the effects of pre-sleep creatine monohydrate supplementation on anaerobic performance and muscle damage markers in recreationally active females. Participants will be randomly assigned to receive either 5 grams of creatine monohydrate or a placebo 30 minutes before sleep for seven consecutive days. Anaerobic performance will be assessed using the Wingate Anaerobic Test, evaluating peak and average power output and fatigue index. Blood samples will be collected before and after the supplementation period to analyze markers of muscle damage, including creatine kinase and lactate dehydrogenase. This study aims to provide insight into the efficacy of short-term, time-specific creatine supplementation for enhancing performance and recovery.
