Raquel Castanha: Strength Training Boosts Running Economy
Strength training enhances running economy by improving the recruitment and efficiency of larger muscle fibers (Type 2A). This means runners expend less energy for the same pace, allowing them to run further and faster with the same effort. The key is progressive overload, using external weights to stimulate these fibers effectively. This improved efficiency is crucial for tolerating demanding efforts like uphill running.
Debunking the 'Heavy Runner' Myth
The fear that strength training will make runners too heavy and hinder performance is largely unfounded. Significant muscle gain that impacts running requires a dedicated focus on hypertrophy and caloric surplus. For most runners incorporating standard strength routines twice a week, the primary outcome is improved strength and efficiency, not detrimental weight gain. The benefits of enhanced muscle function and injury prevention far outweigh any perceived negative impact on weight.
