The science of "relaxing". How can you relax and improve your performance?

"Where and where to relax?" "Where and where to put more effort?" We introduced specific points and recommended practice methods. It is also a part common to all competitions, so I hope you can imagine replacing the "hip joint, knee joint, foot" part with other competitions ↓ [Baseball pitching and volleyball Attack] hip joint → shoulder joint knee joint → elbow joint foot → hand [Things that use tools such as baseball batting, golf, and tennis] Hip joint → base of arm (joint from trunk) Knee joint → The part of the hand that holds the tool Feet → tip of tool * Subtitles may be wrong. Thank you kindly look forward for your understanding. We plan to add subtitles to all past videos, but we have not been able to add subtitles to many videos yet. We apologize for the inconvenience. Videos with subtitles are listed at the bottom. Also, if there are any languages you would like us to add, let us know in the comments. ーーーーーーーーーーーーーーーーーーーーーーーーー ▼Index▼ 0:00~ Opening 0:30~ summary 0:47~ Adverse effects of straining (mainly 3) 1:31~ Why is the speed slowing down? 4:24~ Why is the control messed up? 4:58~ Antagonistic muscles brake 6:33~ What is the timing to relax and put in? 12:17~ Purpose of full-strength training 16:14~ Notes on full-force training 17:57~ Concrete examples of all-out training ▼List of videos with subtitles added▼ [Volleyball] How to Spike a Volleyball (Part 1/2) https://youtu.be/6Qb6ymV4Us0 [Volleyball] How to Spike a Volleyball (Part 2/2) https://youtu.be/51SZ_FPEPmI [Volleyball] How to jump higher in volleyball https://youtu.be/K7zmt3XtmIc [Volleyball] how to generate topspin in volleyball. https://youtu.be/jlEkneEKi4s [Volleyball] Explain 3 common mistakes in receiving! https://youtu.be/fLXR1zMOMcU [Volleyball] The most important thing to pass (bump) is dynamic vision! https://youtu.be/yyGDnClUgW0 [Volleyball] Explain how to make your steps faster! https://youtu.be/5gImU2nWAFA [Volleyball] Scientifically explain important footwork for spike receiving (Dig) https://youtu.be/LccgOkO48hg The science of "relaxing".
