Feasibility is not one of the basic principles of sports training. The other options are fundamental principles that guide sports training.

Introduction:
Sports training involves a systematic and structured approach to enhance an athlete's performance. It is based on several principles that guide the training process. These principles help trainers and athletes to design effective training programs and achieve optimal results. Let's discuss the basic principles of sports training and identify which one is not part of them.

1. Active Participation:
Active participation refers to the involvement of the athlete in the training process. It is crucial for athletes to actively engage in their training sessions to maximize their potential. This principle emphasizes the importance of athletes taking responsibility for their own development and actively participating in the training activities.

2. Increasing the Training Load:
Increasing the training load is a fundamental principle of sports training. It involves gradually increasing the intensity, duration, and frequency of training sessions over time. This progressive overload helps athletes adapt and improve their performance. By gradually increasing the training load, athletes can prevent injuries and achieve continuous improvement.

3. Feasibility:
Feasibility is not one of the basic principles of sports training. However, it is an important consideration in the planning and implementation of a training program. Feasibility refers to the practicality and realistic nature of the training program. It takes into account factors such as the athlete's physical capabilities, available resources, time constraints, and individual circumstances. A feasible training program ensures that the goals can be realistically achieved within the given constraints.

4. General and Specific Training:
General and specific training is another key principle of sports training. It involves a combination of general physical preparation (GPP) and specific physical preparation (SPP). GPP focuses on developing overall physical fitness and includes activities such as strength training, endurance training, and flexibility exercises. SPP, on the other hand, is tailored to the specific needs and demands of the sport. It includes sport-specific drills, skill development, and tactical training. Both types of training are necessary for well-rounded athletic development.

Conclusion:
In conclusion, the basic principles of sports training include active participation, increasing the training load, and general and specific training. Feasibility, although an important consideration in designing a training program, is not one of the fundamental principles. By understanding and applying these principles, athletes and trainers can optimize their training programs and achieve their desired performance outcomes.
