Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Other: Group1 (Resistance trained individuals)
Resistance trained individuals (>3 sessions per weeks for ≥2 years with a minimum of 1 session per week including leg-based exercises)
|
A resistance exercise session was performed.
Following a warm-up that consisted of five-minutes cycling at a self-selected intensity, as well as three progressive lifts at 50, 75, and 90% 6 rep max (RM), participants performed four sets of six repetitions at 100% of 6RM (as determined by the maximal weight lifted during the maximal strength assessment) of the following lifts; back squat, front squat, good mornings, and Bulgarian split-squat.
Two minutes rest was afforded between sets and exercises.
|
Other: Group 2 (Trained cyclists)
Trained cyclists (competing at a minimum of Category 3 road racing/estimated 10 mile TT of <25 minutes and a training history of ≥5 hours per week for ≥2 years)
|
A high-intensity stochastic cycling session was performed.
The cycling protocol was performed using a magnetically-braked cycle ergometer (Velotron, RacerMate).
Following a 10 minute standardised warm-up including 3 × 3s sprints, participants completed a simulated road-race, consisting of sprints of varied length, differing work to rest ratios and short time-trials.
|
Other: Group 3 (Team sports players)
Team sports players (minimum of University 1st team level e.g.
soccer, rugby union, rugby league, hockey and basketball, playing competitively ≥1x per week for ≥2 years)
|
A simulated team sport protocol was performed.
Participants performed a standardised warm-up consisting of performing three laps of the circuit jogging, and three laps at 50, 75, and 90% of perceived maximal speed.
Participants were then afforded five minutes to perform self-selected stretching prior to commencing the session.
Participants performed two sets of 45 minutes of the simulated team sport protocol, separated by 15 minutes rest.
Each 45 minute period consisted of a one minute circuit repeated 45 times that replicates typical movement patterns observed during team sports and includes walking, jogging, jumping, sprinting, agility, and decelerations.
Each circuit was initiated on the minute, therefore enabling participants to rest following the completion of each circuit.
Pilot testing showed participants completes each circuit in approximately 48-55 seconds (sec) therefore enabling 5-12sec rest after each circuit.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Maximal isometric volume contraction (MIVC)
Time Frame: Up to Day 26
|
Following a five minute warm-up cycling at 100W (Power output of the cycle in watts), participants seated on a dynamometer.
For each participant the chair height, length and dynamometer position were recorded and maintained in subsequent trials.
Participants completed a standardised warm-up consisting of contractions at 50, 75, and 90% of perceived maximal force.
Participants then performed three MIVC of the dominant limb each lasting approximately 3 seconds (sec).
Sixty seconds rest was given in between repetitions with peak force (N) recorded and the best attempt used for subsequent analysis.
|
Up to Day 26
|
Rate of force development (RFD)
Time Frame: Up to Day 26
|
Participants were instructed to stand with their feet approximately shoulder width apart on a force plate, with hands placed on hips.
Participants completed a standardised warm-up consisting of jumps at 50, 75, and 90% of perceived maximum jump height.
Participants were instructed to perform a maximal vertical jump by using their own choice of depth and pace (whilst maintaining hands on hips throughout) and to land with straight legs.
If flight time is exaggerated by participants removing hands from the hips or bending their legs whilst in the air, the test was performed again.
Three maximal efforts were performed with sixty seconds rest in between repetitions, RFD (N·s-1) recorded, and the best attempt used for subsequent analysis.
|
Up to Day 26
|
Countermovement jump (CMJ)
Time Frame: Up to Day 26
|
Participants were instructed to stand with their feet approximately shoulder width apart on a force plate, with hands placed on hips.
Participants completed a standardised warm-up consisting of jumps at 50, 75, and 90% of perceived maximum jump height.
Participants were instructed to perform a maximal vertical jump by using their own choice of depth and pace (whilst maintaining hands on hips throughout) and to land with straight legs.
If flight time is exaggerated by participants removing hands from the hips or bending their legs whilst in the air, the test was performed again.
Three maximal efforts were performed with sixty seconds rest in between repetitions with jump height (cm) recorded, and the best attempt was used for subsequent analysis.
|
Up to Day 26
|
20 meter (m) sprint assessment (Group 1 and 3 only)
Time Frame: Up to Day 26
|
A 20 m runway in an indoor track was marked using cones and two sets of infrared timing gates, one set at each end of the start and finish line.
Participants completed a standardised warm-up consisting of performing 20 m runs at 50, 75, and 90% of perceived maximal effort.
Participants stand 0.3 m behind the start line to avoid premature triggering of the timing system, and were instructed to lead with the same starting leg for all attempts before performing three sprints interspersed with 60sec rest.
Sprint time (sec) was recorded and the best attempt was used for subsequent analysis.
|
Up to Day 26
|
Cycling Time-Trial performance assessment (Group 2 only)
Time Frame: Up to Day 26
|
Following a standardised five minute warm-up at 100 W, with a 10sec sprint at 2 minutes 30 sec, participants completed a 5 minute all-out time trial, covering as much distance as possible.
Participants were initially instructed that they were to cover as much distance as possible in 5 minutes, before being blinded to time and test performance and informed of the half-way stage by the investigator.
Distance covered (m), mean power (W) and work done (J) were calculated and used for subsequent analysis.

Limb Girth
Time Frame: Up to Day 26
|
Lower limb girth was measured at the mid-thigh on the dominant leg.
Mid-thigh was defined as the halfway point between the anterior superior iliac spine and the proximal aspect of the patella.
All measurements were taken with the participant standing in anatomical zero with thigh muscles relaxed.
A line semi permanently marked around the circumference of the dominant thigh to ensure the reliability of measurements between sessions.
The mean of three measurements was used for subsequent analysis.
The same investigator will record the measurements between sessions and intra-rater reliability will be reported

Up to Day 26
|
Range of motion (ROM) assessment
Time Frame: Up to Day 26
|
A goniometer was used to measure the relaxed and flexed knee joint angles of the dominant limb.
Measurements was taken when the participants maximally flexes the knee joint to touch the hip with the heel while keeping the knee joint at the side of the body in the anatomical zero position.
Maximal extension was taken when the participant extends the knee joint as much as possible and was allowed to hold onto a wall for balance.
The mean of three measurements was taken for flexion and extension and ROM was calculated by subtracting flexion from extension.
The same investigator will record the measurements between sessions and intra-rater reliability was reported.
