A high-performance gymnast incorporates Proprioceptive Neuromuscular Facilitation (PNF) into their flexibility training. Which of the following physiological mechanisms best explains why the muscle can be stretched further immediately after an isometric contraction?
When evaluating methods to develop flexibility, a sports scientist compares ballistic stretching with dynamic stretching. What is the primary physiological risk associated with ballistic stretching that is largely avoided by controlled dynamic stretching?
Proprioceptive Neuromuscular Facilitation (PNF) utilizes an isometric contraction followed by a passive stretch. Which inhibitory mechanism is primarily responsible for the increased range of motion achieved?
A high-performance dancer uses a goniometer during their pre-season screening. Identify the specific purpose of using this piece of equipment in flexibility training.

A high-performance rhythmic gymnast is seeking to optimise their Range of Motion (ROM) through advanced training methods.
(a) Compare static stretching and ballistic stretching, focusing specifically on how the stretch reflex affects the safety and efficacy of these methods.
(b) Evaluate the use of Proprioceptive Neuromuscular Facilitation (PNF) by explaining the physiological mechanism of autogenic inhibition and how it allows for a greater increase in flexibility compared to other methods.
