This pilot study tested a virtual program designed to help older men at high risk for fractures reduce their risk of falls and broken bones. The program included personalized exercise plans delivered through a smartphone app and virtual nutrition counseling. Researchers enrolled …

This study tests whether a gamified physical therapy software, called Yoomi, can help older hospital patients exercise safely in their beds. The goal is to see if this fun, interactive approach can preserve muscle strength and function during a hospital stay, reducing the need fo…

This study looked at whether adding robot-assisted walking training to stationary cycling helps people who recently had a stroke and are losing muscle. 53 participants did either cycling alone or cycling plus robot walking for 4 weeks. The goal was to see if the combination impro…

This study tested whether a 12-week virtual exercise program called Vivo could improve leg strength and blood sugar levels in sedentary older adults with prediabetes. 74 people aged 60 and older participated, meeting twice a week online with a trainer. The goal was to see if this…

This study tested whether drinking a set amount of water each day (30-35 ml per kg of body weight) for one week could improve how older adults in nursing homes build muscle protein. Seventeen people aged 65 and older took part. The goal was to see if better hydration could help w…

This study tested whether neuromuscular electrical stimulation (NMES) can help Veterans with blood cancers maintain physical function and reduce fatigue during stem cell transplant. 46 participants used NMES while in the hospital. The goal was to see if this approach could preven…

This study tested whether an online, live strength training program called Vivo is feasible and acceptable for sedentary older adults with prediabetes. Twenty-eight participants took part in 45-minute classes twice a week for 12 weeks. The study measured leg strength, attendance,…

This study explores how weight-loss surgery changes the body's protein needs and whether fast-absorbing milk proteins can help preserve muscle mass and strength. Researchers will measure nitrogen balance and muscle function in 25 adults with severe obesity before and after gastri…

This study looks at how taking caffeine in different ways—daily low doses, gradually increasing doses, or only on workout days—affects muscle growth and strength in 180 young men who don't normally drink caffeine or exercise with weights. Participants will follow two 4-week super…

This study looks at how getting too little sleep and not putting weight on one leg affects muscle strength and balance. Healthy adults who exercise regularly will walk on one leg and sleep either 5 or 9 hours for three days. Researchers will measure muscle size, strength, and how…

This completed study examined muscle cells from 8 children with obstetrical brachial plexus palsy, a birth injury that affects arm nerves. Researchers took small muscle samples during planned shoulder surgery to see if the cells can repair themselves. The goal was to understand w…
