This study set out to compare how different home-based hamstring exercises affect flexibility and muscle properties in young men with tight hamstrings. It tested 68 men doing either long-duration stretching,…
Aging clinical and experimental research2026n = 30
RCTHuman
This study set out to see if combining creatine (a compound stored in muscle that helps regenerate quick energy) and β-hydroxy-β-methylbutyrate (HMB, a muscle-preserving supplement) with exercise could improve mobility…

RCTHuman
This study compared two cardio styles for building muscle when matched for total work and time: HIIT (high-intensity interval training, short bursts of hard effort with rests between) and MICT…
Journal of the International Society of Sports Nutrition2026n = 28
RCTHuman
This study compared two forms of omega-3 supplements, structured triglycerides (STGs) and physical mixtures (PMs), to see which better boosts blood EPA levels and muscle performance. Twenty-eight healthy young men…
Nutrients2026n = 20
RCTHuman
This study looked at whether adding modest carbohydrate-energy supplements boosts muscle growth and strength in trained men. Twenty men with an average of nearly 10 years of lifting experience took…
