Purpose:
The present study investigated the effect of maximal strength training on running economy (RE) at 70% of maximal oxygen consumption (V˙ O2max) and time to exhaustion at maximal aerobic speed (MAS).
Responses in one-repetition maximum (1RM) and rate of force development (RFD) in half-squats, maximal oxygen consumption, RE, and time to exhaustion at MAS were examined.
Methods:
Seventeen well-trained (nine male and eight female) runners were randomly assigned into either an intervention or a control group.
The intervention group (four males and four females) performed half-squats, four sets of four repetitions maximum, three times per week for 8 wk, as a supplement to their normal endurance training.
The control group continued their normal endurance training during the same period.
Results:
The intervention manifested significant improvements in 1RM (33.2%), RFD (26.0%), RE (5.0%), and time to exhaustion at MAS (21.3%). No changes were found in VO2max or body weight.
The control group exhibited no changes from pre to post values in any of the parameters.
Conclusion:
Maximal strength training for 8 wk improved RE and increased time to exhaustion at MAS among well-trained, long-distance runners, without a change in maximal oxygen uptake or body weight.
