This study tested whether a six-week, unsupervised high-intensity interval training (HIIT) running program on campus could improve fitness, sleep, and body composition in sedentary male university students. Fifty-six students were…
This study set out to explore whether lower muscle mass is linked to restless legs syndrome (RLS), a condition that disrupts sleep. Researchers analyzed data from 5,752 adults who underwent…
This study compared how low-load and moderate-load circuit training affect strength, performance, and blood markers in men who already lift weights. Thirty-two trained men were split into groups doing either…
This study set out to see if percussive massage (like from a massage gun) helps with muscle swelling, strength, and soreness after a tough leg workout. They had 37 active…
This study looked at how high-intensity interval training (HIIT), where short bursts of hard effort alternate with easier recovery periods, with or without L-citrulline (an amino acid that may boost…
This study looked at whether vitamin D levels are linked to metabolic health, measured by the TyG index (a score from fasting blood sugar and triglycerides that flags insulin resistance,…
This study compared two exercise approaches, high-intensity functional training (HIFT) and traditional resistance training (RT), for improving metabolic, inflammatory, and physical health in overweight men. Thirty-four men with an average…
This study looked at whether resistance exercise and a high-protein diet could improve metabolic flexibility (the body's ability to switch between burning carbs and fats for fuel) in older men.…
This study set out to see if omega-3 (n-3 PUFA) supplements could boost muscle growth and strength gains from weight training in healthy young men already eating plenty of protein.…
This study looked at handgrip strength (a marker of muscle fitness) and its links to lifestyle and body measures in young Taiwanese adults. It surveyed 501 university students aged 18-25,…
This study set out to assess how exercise affects bone mineral density (BMD) in middle-aged and older men, focusing on different skeletal sites. It pooled data from randomized controlled trials…
This systematic review and meta-analysis looked at how combining aerobic exercise with other interventions affects metabolic, heart, and inflammation markers in men. It pooled data from 14 randomized controlled trials…
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,…
This study set out to compare how men and women respond to a 12-week Mediterranean-style weight-loss diet, focusing on changes in body fat, eating habits, and mental health. It followed…
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…
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…
This study compared two approaches to resistance training, linear periodization (a steady progression of weight up and reps down over months) and undulating periodization (varying weight and reps week to…
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…
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…
This study compared two ways of organising the same lifting session in untrained young men. The test method was cluster set resistance training, meaning a set is broken into small…
This study looked at whether vitamin D levels in the blood are linked to developing sarcopenia (age-related muscle loss) in older adults. It followed 1,292 Korean adults aged 70-84 without…
This study set out to measure how the amount of caffeine in the blood tracks with sleep depth and heart activity. Twenty-one healthy young men took either 160 mg of…
This study set out to see whether exercise training raises resting testosterone in men who were not very active but otherwise healthy. It pooled 11 randomized trials covering 421 men…
This study set out to see whether a regular daytime coffee habit disturbs sleep in young men who already drink it. Twenty men went through three 10 day conditions, daily…
This study set out to see whether doing more weekly sets of resistance training builds more muscle and more strength in men who already train. Trained men were assigned to…
This study looked at whether plunging into cold water after weight training costs a man muscle growth or strength. Sixteen men trained three times a week for seven weeks, half…
This study set out to see if adding protein supplements after workouts and before bed would boost muscle and strength gains from weight training in older men. It compared 41…
This study set out to see whether resting longer between sets changes how much strength and muscle a trained man builds. Twenty-one resistance-trained men did the same routine for 8…
This study set out to see whether shorter rest periods between sets of resistance exercise boost muscle growth signals more than longer rests. Sixteen young men did leg exercises at…
This paper reports two separate experiments on whether cold water after strength training blunts the adaptation to it. In the first, 21 physically active men trained for 12 weeks, twice…
