Endurance training typically focuses on which of the following?

Endurance training primarily aims to enhance stamina, allowing individuals to sustain prolonged physical activities without fatigue. This type of training emphasizes cardiovascular fitness and muscle efficiency over extended durations, which is crucial for activities such as running, cycling, and swimming. By engaging in endurance-focused exercises, such as long-distance running or cycling, the body adapitates through improved oxygen utilization, increased capillary density in muscles, and greater stamina.

While building muscle mass, increasing flexibility, and enhancing explosive power are all important aspects of fitness and performance, they represent different training goals. Muscle mass is more aligned with hypertrophy and strength training, flexibility training targets joint range of motion, and explosive power is developed through plyometric and speed-focused training. Therefore, the focus of endurance training distinctly lies in the improvement of stamina in physical activities.
