- Change from baseline in maximum voluntary contraction force [ Time Frame: 21 days ]Participants will be seated with their right knee fixed at 90°. The right ankle will be restrained by a padded cuff attached in series to a load cell. Participants will be instructed to contract their quadriceps maximally by trying to extending their leg. The load cell will measure the maximum force produced.
- Change from baseline in vertical jump height [ Time Frame: 21 days ]Participants will perform both squat jumps and counter movement jumps on a force plate. Jump height (cm) will be measured.
- Change from baseline in number of push-ups [ Time Frame: 21 days ]Participants will perform the maximum number of push-ups possible in one minute while maintaining proper form. A one minute rest will be given and then they will repeat the same procedure.
- Change from baseline in number of 10RM squats [ Time Frame: 21 days ]Participants will complete as many reps of back squats possible using the 10 repetition maximum weight established during familiarization.
- Change from baseline in Wingate test peak power [ Time Frame: 21 days ]Participants will perform a 30 second maximal cycling sprint with the resistance set at 7.5% of their baseline body weight. Peak power, average power, fatigue index and cadence will all be measured.
- Change from baseline in 250 kJ cycling time trial time to completion [ Time Frame: Baseline and 21 days ]Participants will complete 250 kJ (kilo Joules) of cycling on an ergometer which is equivalent to 10km. Time to completion and average power (Watts) will be measured.
- Change from baseline in Pre/Post maximal voluntary contraction force [ Time Frame: 21 days ]Pre/Post quadriceps maximal voluntary contraction force is the difference in maximal voluntary contraction force measured at the beginning and end of each testing session to determine changes in neuromuscular function as a result of the other fatiguing tests.
- Change from baseline in quadriceps voluntary activation [ Time Frame: 21 days ]Participants femoral nerve will be electrically stimulated during the maximal voluntary contraction. Voluntary activation is the difference in muscle force output between the voluntary contraction and the electrically stimulated contraction.
- Change from baseline in Wingate test average power [ Time Frame: 21 days ]Participants will perform a 30 second maximal cycling sprint with the resistance set at 7.5% of their baseline body weight. Peak power, average power, fatigue index and cadence will all be measured.
- Change from baseline in Wingate test fatigue index [ Time Frame: 21 days ]Participants will perform a 30 second maximal cycling sprint with the resistance set at 7.5% of their baseline body weight. Peak power, average power, fatigue index and cadence will all be measured.
- Change from baseline in Wingate test cadence [ Time Frame: 21 days ]Participants will perform a 30 second maximal cycling sprint with the resistance set at 7.5% of their baseline body weight. Peak power, average power, fatigue index and cadence will all be measured.
- Change from baseline in 250 kJ cycling time trial average power [ Time Frame: Baseline and 21 days ]Participants will complete 250 kJ of cycling on an ergometer which is equivalent to 10km. Time to completion and average power (Watts) will be measured.
