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
