Effects of different uphill interval-training programs on running economy and performance

Area of Science:

• Exercise Physiology
• Sports Science
• Biomechanics

Background:

• Uphill running is a common resistance training method for runners.
• Optimal training parameters for uphill intervals are not well-defined.
• This study investigates the dose-response relationship of uphill interval training.

Purpose of the Study:

• To determine the optimal intensity and duration for uphill interval training programs.
• To assess the effects of various uphill interval training programs on physiological and performance measures.
• To provide evidence-based recommendations for training prescription in distance runners.

Main Methods:

• Twenty well-trained runners participated in the study.
• Baseline aerobic, biomechanical, and neuromuscular measures were collected.
• Runners underwent 6 weeks of one of five different uphill interval training programs.
• Post-training assessments were compared to baseline values.

Main Results:

• Highest intensity training was optimal for running economy and neuromuscular adaptations.
• Aerobic measures showed optimal results with moderate-intensity training.
• No consistent optimal parameters were found for biomechanical measures.
• A 2.0% improvement in 5-km time-trial performance was observed across all training intensities.

Conclusions:

• Uphill interval training positively impacts physiological parameters relevant to running.
• High-intensity uphill intervals are beneficial for running economy and neuromuscular function.
• Any high-intensity uphill interval training can be assumed to benefit 5-km time-trial performance.
