Which training builds better athletes? study pits eccentric vs concentric
NCT ID NCT07329348
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 79 male soccer players aged 18-30 to see how two different resistance training methods affect strength and endurance. One group did accentuated eccentric training (focusing on the muscle-lengthening phase) and the other did concentric training (focusing on the muscle-shortening phase), both using resistance bands for 8 weeks. The goal was to find out which approach improves athletic performance more.
