RECOVERY

This study tested whether a heart rate variability biofeedback program—using a sensor and smartphone app to guide slow breathing—is practical and helpful for adults in residential treatment for opioid use disorder. Thirty-two participants practiced daily for three weeks. Research…

This study looked at whether taking a whey protein supplement twice a day helps adolescent soccer players improve their performance, recover faster, and change body composition during a 10-12 week competitive season. Thirty-one high school players aged 13-18 took either the prote…

This study looked at whether eating a high-protein yogurt after exercise helps muscles recover better overnight compared to a flavored water jelly. 26 healthy adults aged 18-45 completed exercise sessions and had their muscle function, soreness, and readiness to exercise measured…

This study tested whether taking tart cherry supplements for 7 days helps muscles recover after intense exercise. 21 healthy, active adults did arm exercises and took either a tart cherry supplement or a placebo. Researchers measured muscle strength, soreness, and inflammation. T…

This study tested whether taking ashwagandha (KSM-66) daily for 42 days helps athletes recover from training and improve muscle strength. 56 rugby and water polo players took either 600 mg of ashwagandha or a placebo. Researchers measured stress hormones, muscle soreness, and per…

This study tested whether foam rolling helps elite swimmers recover faster after intense sprint training. Fifteen national-level swimmers did hard sprints, then either used foam rolling or swam gently to recover. Researchers measured heart rate variability to see which method wor…

This study looked at whether whole-body cryotherapy (extreme cold exposure) helps muscles recover after exercise-induced fatigue. Thirty healthy male university students ran until tired, then either sat in a freezing chamber or rested normally. Researchers measured leg strength, …

This study tested whether stimulating a nerve in the ear (vagus nerve) right after running helps the body recover faster. Sixty healthy young adults who don't exercise regularly took part. Researchers measured heart rate and lactic acid levels to see if the stimulation made a dif…
