Fartlek training includes which of the following?

Fartlek training is a form of continuous exercise that incorporates varying intensities, making it a dynamic and flexible training method. This technique originated in Sweden and translates to "speed play." It allows athletes to alternate between fast and slow segments during their runs or workouts, simulating the unpredictable nature of competition.

In contrast to other training methods, fartlek training provides the benefits of both aerobic and anaerobic workouts. Athletes can adjust their pace and effort based on their goals and surroundings, making it a versatile approach. For example, a runner might sprint for one minute and then jog for two minutes, repeating this cycle throughout their workout. This variability helps improve speed, endurance, and overall performance.

The other options do not accurately describe fartlek training. While rest or recovery periods can be part of training regimens, they are not a defining characteristic of fartlek. Static stretching is not a component of this training style; instead, dynamic movement and continuous exertion are emphasized. Relying solely on sprinting drills would limit the benefits that fartlek aims to provide through a blend of pacing and intensity.
