Effects of Stretching Isquiotibials in Water and on Land in Healthy Adutls for Flexibility: a Randomized Controlled Trial.

Comparison of therapeutic intervention to gain range of motion at the hip joint within therapeutic in water and on land. Stretching is a therapeutic maneuver used to increase the length of shortened soft tissue structures and thereby gain range of motion; for that, innumerable procedures within Physiotherapy use it for the benefit of patients. The work in question is justified by the need to seek the means that can promote a better performance in the application of the stretching procedure, called Proprioceptive Neuromuscular Facilitation, in a universe of pre-selected volunteers. It is a relevant and feasible study, hoping that its results may benefit future patients, with better results and faster responses. What is the medium that leads to better results in a program using the proprioceptive neuromuscular facilitation technique? Hypotheses: a - Probably the heated aquatic environment, in a range of 32 ° to 36 ° C, will promote a better result, since the heat increases the collagen's distensibility. b - Perhaps the heat, by increasing the excitability threshold of nerve fibers, triggers the "protective reflex" later, which may promote a more vigorous elongation without the protective response. c - Possibly the relaxation promoted in the aquatic environment, could influence the gains obtained in the swimming pool.
