The time that should be devoted to specific training before starting sports participation depends on the sport.
To practice a sport it is necessary to follow a series of previous preparation activities to avoid injuries and overexertion that affect the body.
Therefore, if a person is going to start practicing a sport, he should start with short workouts that activate his body and adapt him to a training routine.
Subsequently, you should increase the intensity of your workouts without overexerting your muscles. Once the person is in good health conditions (between 6 and 12 months) he can begin to perform specific exercises for the sport that he is going to practice.
The specific exercises depend on the sport to be practiced, for example:
- Soccer mainly requires speed and strength in the lower body to be able to run with the ball.
- Cycling requires endurance, flexibility and strength to be able to ride a bicycle for several hours at a time without feeling pain and being able to climb hills.
- Basketball requires speed, flexibility and strength throughout the body to be able to run across the court with control of the ball.
Specific exercises must be practiced for at least 6 months so that the body has adapted to the exercise and the quality of the player has improved.
