弹力带训练八大原则
Elastic resistance is a unique mode of training
弹性阻力是一种独特的训练模式
1、Elastic Resistance Force
depends on 3 factors
(弹性阻力取决于3个因素)
Force(力) = K * CSA * ΔL
K Elastic coefficient
(consistent within brands)
(弹性系数)
CSA Cross Section Area
(amount of material)
(横截面积)
ΔL Change in length
(elongation)
(长度变化)
2、Force-Elongation(力-伸长率)
• Elastic resistance is based on percent elongation% = [(final - resting) / (resting)] * 100%
(弹性阻力随伸长率变化) =[(最后的长度-原始长度)/原始长度]* 100
Thera-Band的同种颜色的产品,当长度增加百分比一样时,产生的力也是一样的,与原始长度无关!
3、Torque & the FA(力矩和力的角度)
Torque = Force * Lever Arm * sine (Force Angle)
力矩=力*杠杆臂*正弦(力的角度)
4、How long should the band be?
(应使用多长的训练带?)
Use starting length of band or tubing equal to length of lever arm
(使用初始长度等于杠杆臂长度的训练带或训练管)
5、Where do I place the origin?
(起点放在哪里?)
Align the origin in line with the axis of rotation
(起点与旋转轴处于同一直线)
Ensure Force Angle is 0-15° at end range (physiologic end range, where muscle is at it’s shortest length)
(确保在ROM终点角度时力的角度为0-15°)(生理学终点角度,此时肌肉最短)
Keep band within plane of motion
(训练带保持在运动面内)
6、Exercise Dosing : Volume & Intensity
(训练量:数量和强度)
目标 阻力
力量和爆发力 3-6 RM
大强度运动耐力和速度 10-12 RM
低强度运动耐力 20-25 RM
7、Elastic Resistance Training Dose-Response
(弹性阻力训练剂量反应)
• 6-12 weeks training
• 3 times per week
• 2-3 sets
• 8-12 RM (10-15RM for older)
• 12-14 RPE
• gradual increase in sets, repetitions, & resistance
• 6-12周训练
• 每周3次
• 2-3组
• 8-12RM(老年人则10-15RM)
• RPE评分为12-14
• 逐渐增加组数、重复次数和阻力
8、Elastic Resistance Progression
(弹性阻力渐阶)
• Increase repetitions or resistance
• Progress to next color level to maintain proper biomechanics
– Don’t “shorten-up” on the bands; it will change the biomechanics of the exercise
– Doubling the band/tubing will double the resistance
• Increase the challenge of the exercise by changing posture, movement or stability
