Arms and Interventions

Arm	Intervention/Treatment
Experimental: Maximal-intent Resistance Training The MI group was instructed and encouraged to deliberately commit to exerting maximal effort and force during the concentric phase of the leg press with the intention of achieving the greatest velocity possible.	Other: Leg Press Resistance Training Machine Participants used said unilateral leg press at 60% one-repetition max for either 3 sets x 5 reps, or 5 sets x 5 reps, at either maximal- or controlled-tempo-intent.
Experimental: Controlled-tempo Resistance Training While the CT group followed the metronome for both eccentric and concentric phases.	Other: Leg Press Resistance Training Machine Participants used said unilateral leg press at 60% one-repetition max for either 3 sets x 5 reps, or 5 sets x 5 reps, at either maximal- or controlled-tempo-intent.

Outcome Measures

Primary Outcome Measures

Quality-of-life [The time frame for my testing intervals will be conducted at specific time points: at baseline, Week 1, Week 4, and Week 9, out of a total study duration of 9 weeks.]
Participant quality of life (focus group questions & SF-36)

Secondary Outcome Measures

Balance [The time frame for my testing intervals will be conducted at specific time points: at baseline, Week 1, Week 4, and Week 9, out of a total study duration of 9 weeks.]
Using the biodex SD to do a 3 x 20s double-foot eyes-open balance test on Level 6.
6-minute Walk Test (6MWT) [The time frame for my testing intervals will be conducted at specific time points: at baseline, Week 1, Week 4, and Week 9, out of a total study duration of 9 weeks.]
a "brisk"-paced 6-minute walk test.
Timed-up-and-go (TUG) [The time frame for my testing intervals will be conducted at specific time points: at baseline, Week 1, Week 4, and Week 9, out of a total study duration of 9 weeks.]
Standing from a chair, walking to a point 3 metres away, turn, and return to the chair as quick as possible whilst walking.
30-second sit-to-stand (30s-STS) [The time frame for my testing intervals will be conducted at specific time points: at baseline, Week 1, Week 4, and Week 9, out of a total study duration of 9 weeks.]
Maximal amount of repetitions a participant can stand up from a chair in 30-seconds.
Strength (1RM) [The time frame for my testing intervals will be conducted at specific time points: at baseline, Week 1, Week 4, and Week 9, out of a total study duration of 9 weeks.]
Participants one-repetition max on leg press
BMI [The time frame for my testing intervals will be conducted at specific time points: at baseline, Week 1, Week 4, and Week 9, out of a total study duration of 9 weeks.]
Additional measures calculated from participants test results
