Strength Training Improves Running Economy Durability and Fatigued High-Intensity Performance in Well-Trained Male Runners: A Randomized Control Trial
ABSTRACT
Introduction
Strength training improves running economy (RE) in a non-fatigued state and performance after prolonged exercise at moderate intensity. However, it is unknown if strength training improves RE durability at marathon race intensity, or high-intensity performance akin to the final stages of a competitive race. This study quantified the effect of a supplementary 10-week strength training program on RE throughout 90 min of running in the heavy-intensity domain, and subsequent fatigued performance in runners.
Methods
Twenty-eight well-trained male runners (maximal oxygen uptake (
Results
A large interaction effect of training x group x run time was found for RE (p = 0.003, ηp 2 = 0.13), with E + S improving vs E at 90 min (-2.1% vs +0.6; p = 0.04). For TTE, a large group x training interaction effect was detected (p = 0.004, ηp 2 = 0.28), changing by +35% in E + S and -8% in E.
Conclusions
This study demonstrated that adding strength and plyometrics training to a programme of endurance running improved RE durability and substantially increased high-intensity TTE at the end of a 90 min run in the heavy intensity domain in well-trained male runners.
