Taking baseball as an example, there is currently no unified international or league official regulation for baseball players' rope skipping standards, but according to common vocational training requirements and physical fitness testing practices, the following information is available for reference:

1. Basic standard reference

Professional athletes: usually more than 140-160 times per minute (one-foot rotation counting, that is, 1 touch of the left and right feet), and the excellent can reach more than 180 times.

Youth/Amateur Training: 120-140 beats per minute may be required, depending on age and training goals.

2. Training Purposes

Agility: Improve foot speed and reflexes, especially for running and guarding.

Cardiorespiratory Endurance: Enhances the ability to exercise consistently during competitions.

Coordination: Improves hand-foot coordination, which is conducive to the smoothness of hitting and defending movements.

3. Special training variants

Double Jump Rope (one rope swing and two laps): Pros may need to reach 60-80 reps per minute, with a focus on explosiveness.

One-legged jump: Targeted to strengthen the legs, often used in pitcher training.

4. References

In the youth training of Japanese professional baseball teams, some teams set 160 times in 1 minute as the reference line for the selection of newcomers.

In MLB spring training in the United States, rope skipping is often used as a warm-up event, and high-level players can continue to jump at high speed for 3-5 minutes.

5. Precautions

Proper landing position (forefoot on the ground) is required to reduce pressure on the knee.

Vocational training is often combined with switchback running and ladder training to comprehensively improve mobility ability.

Recommendations are based on the requirements of the team or training program, and strength and conditioning coaches often set differentiated goals based on the player's position (e.g., outfielders need more explosiveness) and individual fitness.
