The Impact of Strength Training on Running Economy
Strength training is recognized for its ability to improve running economy, particularly in un-fatigued conditions, which enhances overall running performance. The podcast discusses a study that aimed to determine whether these benefits extend to prolonged fatigue, where endurance runners often struggle. The researchers hypothesized that strength training could enhance durability, defined as the physiological resilience during fatigue, a critical factor for long-distance runners. By exploring the connections between strength training, running economy, and durability, the study sheds light on how endurance can be maintained even as fatigue sets in.
Study Design and Participant Engagement
The study involved well-trained male runners who were accustomed to longer distance running, with rigorous selection criteria to ensure participants were capable of handling the stress of a 90-minute treadmill run at high intensity. Researchers successfully recruited a sample of 38 participants, ultimately dividing them into two groups: a control group and a strength training cohort. The strength training group performed exercises such as leg presses, maximum strength movements, and plyometrics twice weekly over a 10-week period. The high retention rate showed participant engagement, with 99% adhering to the training schedule, which enhanced the study's reliability and overall findings.
Physiological Measurements and Protocols
To assess the impact of strength training, the researchers conducted various physiological tests before, during, and after the training intervention. They measured factors such as running economy, lactate thresholds, and maximum oxygen uptake (V̇O2max), along with body composition through advanced imaging techniques. These assessments aimed to understand how strength training influenced aspects of performance before and during strenuous efforts. The comprehensive testing protocol, including time to exhaustion and changes in physiological responses during entrenched fatigue, provided valuable insights into the dynamics of running performance.
Key Findings and Performance Improvements
The results indicated a significant improvement in the strength training group, particularly in their ability to sustain high-intensity efforts for longer durations, translating to a 35% increase in time to exhaustion. Interestingly, while there were no initial gains in running economy during fresh conditions, improvements were noted as fatigue set in, suggesting better efficiency under stress. The improved running economy during fatigue was significant, reducing relative oxygen consumption and enhancing durability for long-distance running. These findings highlight the importance of incorporating strength training into a runner's regimen, particularly for those aiming to improve performance in fatigued states.
Practical Implications for Recreational Runners
For recreational runners, the insights from the study underscore the necessity of integrating strength training into their routines to improve endurance and performance. Key suggestions include exploring a variety of exercises to stimulate different muscle groups, emphasizing explosive strength movements, and progressively increasing weights to maximize training efficacy. Additionally, incorporating plyometric exercises can enhance the overall performance by mimicking the demands faced during races. As strong physiological foundations can prevent injuries while optimizing training efficiency, amateur runners are encouraged to adopt structured strength training programs alongside their running.
In this episode of the Run Smarter Podcast, Brodie sits down with researcher and lecturer Dr. Michele Zanini to discuss his groundbreaking new study: "Strength Training Improves Running Economy Durability and Fatigued High Intensity Performance in Well-Trained Male Runners."
We dive into what durability actually means in a running context, why it matters, and how strength training—done the right way—can help you maintain performance under fatigue and finish your races stronger.

📌 Key Takeaways for Runners:
Strength training doesn’t just help with injury prevention—it can enhance fatigue resistance.
Running economy improvements may be more visible during fatigue, especially for well-trained runners.
Strength protocols should include progressive loading, low reps with high intent, and strategic plyometrics.
Even without fancy lab equipment, runners can apply these training principles and see real-world performance gains.
