AEROBIC CAPACITY

This trial compares two high-intensity training programs—CrossFit and running-based HIIT—in elite male distance runners who live and train at moderate altitude. Over six weeks, participants train five days per week and undergo tests for aerobic fitness, strength, and blood marker…

This study compared supramaximal interval running (SIR) and small-sided games (SSG) in 40 elite male football players over six weeks of preseason training. Both methods improved fitness, but SIR led to greater gains in aerobic capacity, body composition, and anaerobic markers. Th…

This study looked at how an eight-week high-intensity training program affects fitness and certain blood markers in 40 male kickboxers. The goal was to see if changes in substances like myostatin and irisin could predict improvements in aerobic capacity. The findings may help exp…

This study looked at 42 teenage soccer players to see how different training drills affect their fitness and enjoyment. Researchers compared three types of exercises: the standard Yo-Yo running test, a version where players dribble a ball, and small-sided games (like 3v3 or 4v4).…

This study looked at how a supplement called HMB, combined with exercise, affects muscle proteins and fitness in two groups: trained athletes and people who are not very active or are malnourished. Over 21 days, participants took HMB or a placebo and underwent exercise tests. The…

This study looked at 32 female volleyball players aged 15-18 to see if high-intensity interval training (HIIT) or high-intensity functional training (HIFT) improves performance more. Players did their assigned training twice a week for 12 weeks, in addition to regular practice. R…

This small study tested whether temporarily restricting blood flow to the legs (ischemic preconditioning) could improve aerobic energy supply and kick performance in 16 elite taekwondo athletes. Each athlete did a kicking test twice, once with real pressure and once with a sham, …
