Low-dose Maximal-intent Versus Controlled-tempo Resistance Training on Quality-of-life in Adults

Study Overview
=================
Brief Summary
-----------------
The aims of this study were to: Compare the effects of low-dose Maximal Intent and Controlled Tempo Resistance Training on untrained healthy adults' quality-of-life, functional capacity, and strength. Qualitatively explore perceptions of Maximal Intent and Controlled Tempo Resistance Training.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Maximal-intent Resistance Training<br>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<br>* 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.<br>|
| Experimental: Controlled-tempo Resistance Training<br>While the CT group followed the metronome for both eccentric and concentric phases. | Other: Leg Press Resistance Training Machine<br>* 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.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Quality-of-life | Participant quality of life (focus group questions & SF-36) | 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. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Balance | Using the biodex SD to do a 3 x 20s double-foot eyes-open balance test on Level 6. | 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. | 
| 6-minute Walk Test (6MWT) | a brisk-paced 6-minute walk test. | 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. | 
| Timed-up-and-go (TUG) | Standing from a chair, walking to a point 3 metres away, turn, and return to the chair as quick as possible whilst walking. | 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. | 
| 30-second sit-to-stand (30s-STS) | Maximal amount of repetitions a participant can stand up from a chair in 30-seconds. | 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. | 
| Strength (1RM) | Participants one-repetition max on leg press | 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. | 
| BMI | Additional measures calculated from participants test results | 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. | 
| Strength-to-mass | Additional measures calculated from participants test results | 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. |
