Why are slow-twitch muscles more beneficial than fast-twitch muscles for endurance activities?

Answer 1

Slow-twitch muscles are more beneficial for endurance activities because they are designed to sustain prolonged contractions without getting tired quickly. They have a higher capacity for aerobic energy production, which allows them to efficiently use oxygen to generate energy for longer periods of time. This makes them well-suited for activities that require sustained effort, such as long-distance running or cycling. In contrast, fast-twitch muscles are better suited for short bursts of intense activity but fatigue more quickly, making them less ideal for endurance activities.
