Use various drills to build , to refine , or reinforce different stroke phases , but remember drills should be taught " as another stroke " - drill perfection is required to teach perfect technique 利用多种多样的训练来构成、精心练习和增强不同划臂阶段的游泳技术。但是,要记住训练也有可能造成"旧病未愈又添新病" ,运动员完美无缺的训练需要教练员在技术上完美无暇的讲授。
Increase swimmer interest and focus by " inventing " new drills , or allowing swimmers to " invent " drills themselves - remember these drills need to utilize sound stroke principles that do not lead to stroke flaws or injuries 通过"发明"新的训练方法,来增加游泳运动员的兴趣和注意力,或者让游泳运动员自己"发明"训练方法, - -但是,要记住这些训练方法需要应用正确的不会导致划臂缺陷或运动伤害的划臂原则来指导。
If a swimmer uses two extra strokes per length in a short course pool , it means that eight extra strokes are used per 100 yards / meters and four hundred eighty additional strokes per 6000 yard / meter workout , hence much more muscle fatigue which can cause pain 假如一个游泳运动员在短池里游泳时,每25米额外增加两次划臂,那么,每100米就要额外增加八次划臂,每6000米就要额外增加480次划臂的运动量,从而引起肌纤维膜更加紧缩而疼痛。
Applying too direct or too much force during the " catch " phase of the stroke - if during the " catch " phase of the stroke , too straight or too strong a force is used , the head of the humerus is rotated into the deltoid muscle and causes tendonitis , and / or the scapula is pushed against the rotator cuff muscles , causing pain or possible tissue damage 在划臂的“抓水”阶段,手臂径直抓水或过分用力一如果在划臂的“抓水”阶段,手臂太直或过分用力,肱骨头就会旋进三角肌引起肌腱炎,肩胛骨也会挤压轴转肌而引起肌肉疼痛或组织损伤。
Collapsing the elbow across the body during the underwater propulsive phase of the stroke - if the elbow is dropped during the propulsive phase of the stroke , the head of the humerus is , again , rotated into the deltoid causing friction and tedonitis , and / or the scapula is pushed against the rotator cuff muscles , causing pain or possible tissue damage 在划臂的“抓水”阶段,手臂径直抓水或过分用力一如果在划臂的“抓水”阶段,手臂太直或过分用力,肱骨头就会旋进三角肌引起肌腱炎,肩胛骨也会挤压轴转肌而引起肌肉疼痛或组织损伤。
