Strength training plays an important role in the preparation of endurance athletes. In addition to contributing to force production, it can improve the muscle's ability to sustain repeated efforts and maintain movement quality throughout exercise.
Are muscular strength and muscular endurance the same thing?
Although they are related, muscular strength and muscular endurance represent different capacities.
Muscular strength is associated with the ability to produce force, while muscular endurance refers to the ability to sustain force production for longer periods or repeat it without a significant decline in performance.
In endurance sports, both are relevant. An athlete needs to produce enough force to run, cycle, or swim, but also needs to maintain that force production over prolonged periods.
What happens to the muscles during prolonged exercise?
As exercise continues, muscular fatigue increases and the ability to maintain force production may decrease. Changes in motor unit recruitment, energy availability, and contractile function contribute to this decline.
This is where muscular endurance becomes important. The greater the ability to sustain force production, the greater the potential to preserve movement mechanics and efficiency throughout the race.
How can strength training contribute to endurance performance?
Including strength training can promote neuromuscular adaptations that improve the ability to produce and sustain force.
For runners, cyclists, and triathletes, this can be particularly relevant in situations where mechanical demands increase, such as climbs, accelerations, pace changes, and the final stages of a race.
In addition, strength training does not have to compete with specific endurance training. When properly structured, it can complement preparation by considering training volume, intensity, frequency, and how close the sessions are to key workouts.
Muscular endurance is also a matter of strategy
Developing maximal strength is not enough if the athlete cannot use it efficiently during prolonged exercise.
The combination of strength and muscular endurance makes it possible to work not only on the ability to produce force, but also on the ability to repeat that effort while maintaining movement patterns and minimizing the decline in performance associated with fatigue.
Therefore, training prescription should consider the sport, race duration, and the athlete's specific demands.
Strength is also part of race preparation
For endurance athletes, strength training should not be viewed simply as an accessory. It can be part of the strategy to develop the muscular capacity required to sustain effort throughout the race.
The goal is not simply to lift more weight, but to develop muscles capable of producing force, repeating that work, and continuing to respond to the demands of exercise when fatigue is already present.
