What type of training incorporates interval running, jogging, sprinting, and walking?

Fartlek training is a form of training that involves varying intensity and speed throughout a workout, incorporating different paces such as running, jogging, sprinting, and walking. The name "Fartlek" comes from Swedish, meaning "speed play," highlighting the playful and flexible nature of this training method.

This type of training not only helps to improve cardiovascular fitness and speed but also mimics varied conditions that athletes might encounter in competition, allowing for better adaptability and performance. The integration of different speeds and the less structured format make it unique compared to other structured training methods.

While interval training involves alternating between high-intensity and low-intensity exercises, its focus is often more rigid and specific regarding the timing and intensity of work and rest periods. Endurance training primarily emphasizes longer, steady-state activities aimed at building stamina. Circuit training typically incorporates various exercises targeting different muscle groups rather than focusing on speed variations during running. Thus, Fartlek training encapsulates the essence of mixing all those running speeds into a coherent workout regime.
