Kestävyysala

Kestävyysala, also known as the "endurance zone," is a concept in sports science and exercise physiology that refers to the range of heart rates and intensities at which the body can sustain prolonged physical activity without accumulating excessive fatigue. This zone is typically defined as 60-85% of an individual's maximum heart rate (MHR). The exact percentages may vary depending on the specific activity and individual fitness levels.

The kestävyysala is crucial for activities that require sustained effort over an extended period, such as long-distance running, cycling, swimming, and cross-country skiing. Training in this zone helps improve cardiovascular fitness, endurance, and overall athletic performance. It also plays a significant role in weight management and overall health, as it promotes the burning of calories and fat for energy.

To determine an individual's kestävyysala, athletes and fitness enthusiasts often use heart rate monitors or estimated heart rate ranges based on age and resting heart rate. Regular training in this zone, combined with appropriate recovery and nutrition, can lead to improved endurance and overall fitness. However, it is essential to avoid prolonged exercise at intensities above 85% of MHR, as this can lead to excessive fatigue, injury, and reduced performance.
