Summary

Athletes have been exposed to an ever increasing training load and subsequent biomechanical overload due to a constant demand for performance enhancement. As a result, it is observed an increased rate of musculoskeletal problems, including spinal biomechanical dysfunctions that are often asymptomatic. These dysfunctions are believed to negatively influence a wide range of mechanical and physiological parameters such as muscle strength, range of motion, and symmetry, what could potentially influence sports performance. Spinal Manipulative Therapy (SMT) is a safe and effective therapy for musculoskeletal disorders that has been increasingly utilized in sports. SMT purpose is to correct spinal joints biomechanical dysfunctions using a high-velocity, low-amplitude movement, applied at the paraphysiological space, beyond the passive joint range of motion. Kinetic and kinematic symmetry can be measured in commonly utilized physical functional tests often used as indicators of athlete's performance. Symmetry Index calculation is used to verify bilateral asymmetries in static and dynamic tests.

Detailed description

Therefore, the objective of this randomized controlled trial study is to measure the immediate effects of lumbar SMT on kinetic and kinematic symmetry of asymptomatic athletes, through of the use of three commonly used functional tests: Static posture, Free Squat, and Countermovement Jump (CMJ) are often used as indicators of athlete's performance. These quantitative data is important to assess training effectiveness and prevention/ rehabilitation programs outcomes. To our knowledge this is the first study on literature that measured the immediate effects of SMT on kinetic and kinematic symmetry.

• Asymptomatic Condition

Interventions

Type	Name	Description
PROCEDURE	Spinal Manipulative Therapy	Lumbar (SMT) was performed using Diversified techniques, aiming to correct vertebral dysfunctional lumbar segments. Participants were asked to lay down prone on, to perform spinal motion palpation analysis was in order to evaluate the presence of dysfunction in vertebral segments of lumbar spine.
PROCEDURE	SHAM	The "SHAM" (pre-load positioning SMT) was performed with participant body positioning in the lateral position, as the SMT intervention. The doctor followed the participant through the same position of (SMT) intervention, using the maintenance of set-up position, but no manipulative thrust was delivered. The therapist applied minimal pressure and slid their hands across the skin to mimic the manipulative trust. The position was maintained 30 seconds on each side, and none of force or researcher body weight were putted in this procedure, only minimal pressure common to stabilize the set up position of (SMT).
