About

The present study aims to assess the effects of spinal manipulation therapy on neuromuscular performance.

Full description

The present study will follow a parallel, pre-post design. The aim will be to determine the acute effects of spinal manipulation therapy (SMT) on different neuromuscular properties of recreational cyclists. Specifically, the investigators will measure the maximum force production capacity and muscle activation of the knee extensors concomitantly during a maximal voluntary contraction, as well as the maximum and mean power attained during a Wingate cycling test (i.e., 30 seconds 'all out'). Participants will undergo the tests on two different occasions separated by at least 48 hours and a maximum of 2 weeks. The same tests will be conducted in both testing sessions, but participants will be randomly assigned into two groups (sham or actual SMT) immediately before the second testing session.

Sex: Male

Ages: 18 to 45 years old

Exclusion criteria

• Having suffered an injury in the month before the study that precluded regular exercise practice
• Having suffered any type of spine injury before the study
• Having previously received Spinal Manipulation Therapy

0 participants in 2 patient groups

Sham spinal manipulation

Sham Comparator group

Description:

Participants in the 'sham' group will receive a sham mechanical thrust (force set at level 0) instead of an actual one. In the force level 0, no excursion of the stylus occurs, but the instrument produces the same clicking sound as in the actual SMT condition. Therefore, the subject does not distinguish between intervention or placebo.

Treatment:

Other: Sham spinal manipulative therapy

Actual spinal manipulation

Experimental group

Description:

Participants in the actual actual spinal manipulative therapy (SMT) group will be assessed through the Activator basic method. SMT will be performed with the Activator IV Adjusting Instrument (Activator Methods International, Phoenix, AZ) varying the force level depending on the adjusted segment.

Treatment:

Procedure: Spinal manipulative therapy
