Summary

Intensity is a "qualitative" variable of a muscle stretching protocol, which is very little studied due to its inherent characteristic of the individual being stretched. However, it was pointed out as an important factor for ADM gain. To verify the effects of different intensities of static passive stretching on flexibility, neuromuscular and functional performance in soccer athletes.

Detailed description

It is a randomized, controlled, clinical trial, composed of male subjects, soccer players, randomly divided into 4 groups: Control Group (CG), Experimental Group 1 (GE1), Experimental Group 2 (GE2) And Experimental Group 3 (GE3). Initially, the measurements of flexibility (passive and active), neuromuscular (muscular passive torque, electromyographic activity), and functional (vertical jump and shuttle run test) of non-dominant lower limbs, performed before and immediately after the 1st And 48 hours after the last session. The GC will only be submitted for initial evaluation and final re-evaluation. The experimental groups will undergo a protocol of static passive stretching containing 10 sessions, divided into 3 weekly sessions, with 3 maneuvers of 30 s, but with different intensities (Tolerable Maximum Pain, Maximum No Pain Discomfort, and Stretching Sensation Without Discomfort) Established from a PERFLEX-modified visual scale. Groups with higher static passive stretching intensities (Maximum Tolerable Pain and Maximum Painless Discomfort) are expected to have greater gains in flexibility, with no change in muscle passive torque, electromyographic activity and functional performance, while the intensity of Feeling of Stretching without Discomfort (in a comfort zone) provides a greater decrease of the muscular passive torque, without significant change of the flexibility, in individual athletes of soccer. This work may contribute to the clinical practice of health professionals, since it seeks to improve the elaboration of the clinical prescription of protocols of static passive stretching (whether performed by the individual or not), establishing optimal levels of intensity for a given muscle group.

Conditions

• Contracture of Muscle, Thigh
• Muscle Rigidity
• Strain of Hamstring Muscle (Disorder)

Interventions

Type	Name	Description
OTHER	Passive static stretch	Each experimental group will be submitted to 10 (ten) sessions, with three (3) weekly sessions of static passive stretching, with a 48 h interval between them. Each session will be performed 3 (three) maneuvers containing a duration of 30 seconds, this being the same rest time, performed in all experimental groups.
