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

Detailed 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 criteria: 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

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

Primary outcomes:
measure: Maximal force
timeFrame: On the control session and on the intervention session (immediately after the sham or actual SMT procedure)
measure: Voluntary activation
timeFrame: On the control session and on the intervention session (immediately after the sham or actual SMT procedure)
