Document Summary

Chapter 11 designing programs for flexibility & lower back care. Flexibility training: systematic program of stretching exercises designed to progressively increase the rom of joints over time. Flexibility programs should be individualized: goals, needs, abilities (stretch tolerance and pain threshold, physical activity interests. Stretch tolerance: a measure of the amount of resistive force to stretch within target muscles that can be tolerated before experiencing pain. Classification of stretching techniques: active stretching: the client moves the body part without external assistance.

Applied external force during the stretching phase: assistant needs proper training: overstretching may cause injury, clients need proper training, proper communication between the client & the assistant is needed.
