Unverified80% confidenceFactTime unknown
阻力带阻力随拉伸长度变化（非恒定），标称磅数通常指拉伸至约2.5倍时的阻力，实际动作中末端阻力远高于起始，选档时应留有余量而非顶格购买

Unverified弹力带的阻力磅数标注通常基于100%-250%拉伸范围，实际阻力随拉伸长度显著变化，选购时应关注初始阻力与最大拉伸阻力区间，而非单一数字84% similarUnverified弹力带阻力并非固定值，随拉伸幅度增大而增加，多数产品标注的磅数为拉伸至一定倍数时的阻力峰值，实际训练需结合拉伸长度理解阻力曲线83% similarUnverified弹力带助力磅数标注通常指'最大拉伸时的阻力'，实际助力会随身体上升而减弱，故实际到位助力低于标称值，选购时可略选偏大档位79% similarUnverified阻力越大回弹一致性越难保证，超重带（>40lbs）拉伸行程中后段阻力增长非线性，力量训练精确控制需求高时应分档多带而非单条超重79% similarUnverified阻力越大越练握力但行程完成难度陡增，新手买高阻力(＞50kg)常无法完整闭合导致无效训练；渐进原则应保证能标准完成8-12次77% similar
