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

Comparison of Low-dose Maximal-intent Versus Controlled-tempo Resistance Training on Quality-of-life, Functional Capacity, and Strength in Untrained Healthy Adults: a Randomised Controlled Trial

The aims of this study were to:

1. Compare the effects of low-dose Maximal Intent and Controlled Tempo Resistance Training on untrained healthy adults' quality-of-life, functional capacity, and strength.
2. Qualitatively explore perceptions of Maximal Intent and Controlled Tempo Resistance Training.

Arms and Interventions

Participant Group / 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.

What is the study measuring?

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.
