Clinical Trial Summary

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

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.

Eligibility

Inclusion Criteria:

• Will be recruited from three different local triathlon and cycling clubs.

• Will have to cycle at least 4 hours per week during the preceding 3 months, and to have a cycling experience greater than 2 years

Intervention

Procedure:
• Spinal manipulative therapy
Participants in the actual spinal manipulative therapy group will be assessed through the activator basic method protocol. SMT will be performed with an Activator IV (Activator Methods International, Phoenix, AZ) setting the force at level 3 for the low thoracic spine (T7-T12), and level 4 for the lumbar spine and pelvis.

Other:
• Sham spinal manipulative therapy
Participants in the sham SMT group will undergo a protocol identical to the actual one, with the exception that a sham mechanical thrust (force set at level 0) will be delivered to the targeted areas. 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
