Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will complete a 1 hour exercise bout designed to induce delay-onset muscle soreness where paricipants walk backwards on a 13 degree incline at a speed of 2.2km/h whilst wearing a 10kg weight belt. This will be supervised by an exercise scientist. Immediately following this exercise bout, participants will complete either 10 x 1 minute bouts of whole-body vibration, standing on a Galileo vibration plate set at 26Hz and 4.5mm amplitude, with a 30 second rest between bouts or 15 minutes of static strethcing. This is a randomised crossover study and following a seven day washout, participants will complete the 1 hour of backwards walking followed by the other preventative intervention.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be screened according to American College of Sports Medicine criteria and have all joints assessed for level of functioning. Once they have met the inclusion criteria, participants will be randomly allocated to complete either the intervention or control conditions first using a computer generated list, concealed using individual opaque envelopes and administered by an independent researcher.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation sequencing will be achieved through a computer generated list stratified for gender to ensure that equal numbers of males and females will complete the conditions in the same order.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Crossover
Other design features
There will be a week 'wash-out' for each participant prior to completing the alternate condition.

Summary
Brief summary
This project will investigate the effects of two different exercise modalities to recover from delayed-onset muscle soreness (DOMs) generated by eccentric exercise of the leg musculature. The two recovery modalities are a traditional recovery technique (static stretching) and whole body vibration exercise (WBV) where a person stands on a vibration plate. The traditional technique is commonly used to recover from DOMS but is not associated with increased blood flow in the legs. Increased blood flow in the legs, however, is thought to be a significant factor in the recovery from DOMS. WBV has been shown to significantly increase blood flow in the legs, therefore, it is hypothesised that it will reduce the intensity of DOMS generated by eccentric exercise of the leg musculature (backward slow walking on a treadmill).

The level of DOMs will be assessed by a measurement of shank swelling (lower leg) and a muscle soreness rating. It is known that DOMs reduces strength and power output, and joint range of motion (ROM) in the hip, knee and ankle. These parameters will be measured by a vertical jump for maximum height, muscle activation through electromyography and joint ROM (ankle, knee and hip) with a goniometer. DOMs recovery will also be assessed by recording walking and running patterns since these are significantly affected by DOMS.
