Overview
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.

Outcomes
Primary Outcomes
Peak power
Time Frame: On the control session and on the intervention session (immediately after the sham or actual SMT procedure)
Peak power registered during a 30-second Wingate anaerobic cycling test
Voluntary activation
Time Frame: On the control session and on the intervention session (immediately after the sham or actual SMT procedure)
Electromyographic activity of the vastus lateralis muscle registered during an isometric maximal voluntary contraction of the knee extensors.
Mean power
Time Frame: On the control session and on the intervention session (immediately after the sham or actual SMT procedure)
Mean power registered during a 30-second Wingate anaerobic cycling test
Maximal force
Time Frame: On the control session and on the intervention session (immediately after the sham or actual SMT procedure)
Peak force registered during an isometric maximal voluntary contraction of the knee extensors.
