Which of the following would be appropriate at the power level (phase 5) of the opt model or before athletic competition?
a. corrective flexibilityb. active flexibilityc. functional flexibilityd. relative flexibility

Functional flexibility would be appropriate at the Power Level (Phase 5) of the OPT model or before athletic competition.

Explanation:

The occurrence of Functional flexibility occurs at the transverse plane. It occurs when there is no extension through out the motion's full range or  soft tissue is not extensible through the full range of motion,or essential motion without any compensation. In transverse plane, there is an injury possibility. This type makes use of a method of  dynamic stretching and myofascial release.

There is a requirement of extensibility in the soft tissue multiplaner, integration and a control in neuromuscle for this type of flexibility. There is an  It is appropriation in the power level phase 5 of OPT MODEL before athletic competition.

there are no contact forces mentioned on the list of choices that you've provided.
