What principle ensures training is adapted for individual capacities and limitations?

The principle that ensures training is adapted for individual capacities and limitations is individuality. This principle emphasizes the understanding that each athlete has unique physical characteristics, strengths, weaknesses, and responses to training. Consequently, a training program must be tailored to meet the specific needs and abilities of each person to optimize performance and reduce the risk of injury.

By recognizing individual differences, such as age, fitness level, injury history, and even psychological considerations, coaches and trainers can devise more effective training regimens that cater specifically to the athlete's capabilities, leading to more successful outcomes. Individuality is a fundamental concept in athletic training, as it underscores the importance of personalizing approaches to maximize each athlete's potential.

In contrast, the other principles—progression, specificity, and overload—focus on aspects like the systematic advancement of training intensity, the need for targeted training for specific skills or components, and the necessity of stressing the body for adaptation, respectively. While these principles are essential for effective training, they do not specifically address the variation in individual capacities and limitations that the principle of individuality encompasses.
