Effects of complex training versus heavy resistance training on neuromuscular adaptation, running economy and 5-km performance in well-trained distance runners

This study demonstrated that CT can enhance 1RM strength, CMJ height, 12 and 14 km.h⁻¹REs, 50-m sprints and 5-km running performances in well-trained male distance runners and may be superior to HRT for the development of reactive strength and 16 km.h⁻¹RE, and reduction of BLa concentrations at speed of 16 km.h⁻¹. Young male distance runners could integrate CT into their programs to improve the running performance.
