Why Weightlifting Can Improve Your Muscular Endurance (Ask a Cycling Coach 277)

TL;DR

Strength training, specifically hypertrophy (increasing muscle mass), can improve endurance capabilities by increasing peak force, improving muscular coordination, enhancing movement economy, and increasing phosphocreatine and glycogen storage in type 2 muscle fibers.

Transcript

i'm wondering why building muscle with weightlifting to increase body weight helps with endurance that seems total totally counterproductive right we're kind of bookending this one talking about you know body types way to all that stuff he says i know quite a bit of rowers who weight lifted and gained weight and then improved their endurance power ...

Key Insights

• 🙊 Strength training, specifically hypertrophy, can improve endurance performance by increasing peak force and improving muscular coordination, movement economy, and efficiency.
• 📶 High force, low velocity strength training can lead to maximal strength gains in type 1 muscle fibers.
• 💪 Strength training can increase phosphocreatine and glycogen storage in type 2 muscle fibers, enhancing their endurance capabilities.
• 🥺 Strength training reduces the risk of injuries and allows for more consistent training, leading to faster performance improvements.

Questions & Answers

Q: How does hypertrophy, or increasing muscle mass, contribute to endurance performance?

Hypertrophy increases peak force, allowing for more power production and higher sustainable power output. It also enhances muscular coordination, movement economy, and efficiency during endurance activities.

Q: Can strength training lead to improved endurance capabilities in both type 1 and type 2 muscle fibers?

Yes, high force, low velocity strength training can result in maximal strength gains in type 1 muscle fibers, leading to greater average power in long-distance events. Additionally, strength training increases phosphocreatine and glycogen storage in type 2 muscle fibers, enhancing their endurance capabilities.

Q: Does strength training reduce the risk of injury?

Yes, strength training improves muscular coordination and stability, reducing the risk of injuries during endurance activities. It also allows for more consistent training, minimizing training interruptions and facilitating faster performance improvements.

Q: Will strength training make endurance athletes bulk up?

The likelihood of endurance athletes gaining significant muscle mass is low. Building muscle mass requires specific dietary modifications, high-volume strength training, and even the use of anabolic steroids. Most endurance athletes have a body type (ectomorphic somatotype) that makes it difficult to add significant muscle mass while maintaining high levels of endurance.

Summary & Key Takeaways

• Strength training can improve endurance performance through hypertrophy, which involves increasing muscle mass and peak force.

• High force, low velocity strength training can lead to greater contractile strength in type 1 (slow twitch) muscle fibers and increase phosphocreatine and glycogen storage in type 2 (fast twitch) muscle fibers.

• Strength training improves muscular coordination, movement economy, and efficiency during endurance activities.

• Strength training reduces the risk of injury and allows for more consistent training, leading to faster performance improvements.
