MUSCLE HYPERTROPHY

This study tested whether taking whey protein together with collagen peptides helps resistance-trained men build more muscle and bone density than either supplement alone or a placebo. Forty healthy men aged 18–35 who already lifted weights took one of four supplements for 8 week…

This study looked at whether adding extra carbohydrates to a daily protein supplement helps resistance-trained men build more muscle and strength. Twenty-five men took either a protein-only or a protein-plus-carb supplement for 8 weeks each. The results showed no significant diff…

This study tested whether doing light arm exercises with a blood pressure cuff on the upper arm (blood flow restriction) can build biceps muscle as well as lifting heavy weights. Thirty-three healthy young men who had never done arm training before followed an 8-week program. Res…

This study looked at whether lifting light weights (30% of your max) until you can't do another rep builds muscle and strength as well as lifting heavy weights (75% of your max) in healthy young men who don't usually lift. Twenty-two men did leg exercises three times a week for s…

This study looked at 30 healthy adults who already lift weights regularly. Researchers compared two training methods: one that adjusts weights based on movement speed (velocity-based) and one that uses fixed percentages of maximum strength. The goal was to see which method leads …

This completed study looked at how children (ages 9-13) and adults (ages 18-50) respond to 12 weeks of resistance exercise using either flywheel or traditional weight stack machines. 91 healthy participants were randomly assigned to one of three groups: flywheel training, weight …
