Taking baseball as an example, the reasons why baseball athletes do not train can be analyzed from multiple dimensions, and the following is systematically sorted out:

1. Physical factors

Injury Limitations

Acute injuries: such as a pitcher's shoulder and elbow ligament tear, muscle strain during running base, etc., require mandatory recuperation.

Chronic strain: Wear and tear on the shoulder joint (e.g., labral injury) caused by long-term pitching may force a reduction in training volume.

Physical overdraft

Consecutive high-intensity games (such as 162 games in an MLB season) tend to lead to fatigue accumulation and require periodic breaks.

2. Psychological motivation

Lack of motivation

Long-term repetitive training leads to a decrease in interest (common in young players).

Self-doubt arises during periods of performance bottlenecks (e.g., persistently low strike rates).

High-pressure environment

Psychological shadows (e.g., "pitching phobia") after a critical game error.

Anxiety is triggered by media criticism or pressure from fans.

3. Constraints of the external environment

Team management issues

Controversy over the coach's training style (e.g., overemphasis on physical fitness and neglect of technical details).

Contract disputes (e.g. suspension of training for professional players during salary negotiations).

Family & School

Student players are suspended from training due to college entrance exams, such as NCAA academic eligibility requirements.

A professional player is required to leave the team due to a family emergency, such as a serious illness of a relative.

Fourth, career development options

Transition period adjustments

Veterans reduce the amount of training to prolong their careers (e.g., moving to designated strikes).

Try to cross borders (e.g., participating in business events or baseball commentary).

Decommissioning planning

Players considering retirement may reduce the intensity of their training in advance.
