Intervalliharjoitus

Intervalliharjoitus is a form of training used in sports and exercise, particularly in the context of sprinting and power sports. The term "intervalliharjoitus" is derived from Finnish, where "intervalli" means "interval" and "harjoitus" means "exercise" or "training".

In intervalliharjoitus, athletes perform repeated periods of high-intensity exercise, often at maximum or near-maximum effort, followed by periods of rest or low-intensity exercise. These high-intensity periods are typically shorter in duration than the low-intensity periods, allowing the athlete to recover and maintain a high level of effort throughout the training session.

The goal of intervalliharjoitus is to improve an athlete's anaerobic capacity, power, and speed by pushing them to perform at high levels of intensity for extended periods. By repeatedly exposing the muscles to high-intensity exercise, the athlete is able to gradually increase their lactate threshold and improve their ability to recover from the fatigue associated with anaerobic exercise.

Intervalliharjoitus is often used by track and field athletes, particularly sprinters and long jumpers, as well as by other power athletes such as football and rugby players. The training method has been adopted by coaches and trainers around the world, who incorporate it into their athletes' training programs in order to improve their speed, power, and overall performance.
