What is the primary focus of a sprint on a hill in an interval training context?

In an interval training context, the primary focus of a sprint on a hill is to develop speed and power. This is because hill sprints require a higher level of force production due to the incline, which places greater demand on the muscles, particularly in the lower body. During these sprints, participants engage in fast-twitch muscle fiber recruitment essential for generating power and explosive speed.

Additionally, the steepness of the hill increases the intensity of the workout, making it beneficial for improving anaerobic capacity and enhancing overall athletic performance. This type of training can significantly contribute to a cyclist's ability to maintain a high pace when racing or climbing.

Although endurance building and strength testing can occur during hill workouts, the specific emphasis on speed and power makes option C the most relevant focus in this scenario. Coordination improvement also plays a role in executing hill sprints effectively but isn't the primary objective within the context of high-intensity interval training.
