Study Details

Study Description

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 older adults' quality-of-life, functional capacity, and strength.
Qualitatively explore perceptions of Maximal Intent and Controlled Tempo Resistance Training in older adults.

Older adults are defined as being 60 or more years of age.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Maximal-intent Resistance Training - 3x5 (MI3x5) The max-intent group were 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. This group completed 3 sets of 5 repetitions at 60% one-repetition maximum.	Other: Leg Press Resistance Training (3x5) Leg Press resistance training at 60% one-rep-max for three sets of five repetitions
Experimental: Maximal-intent Resistance Training - 5x5 (MI5x5) The max-intent group were 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. This group completed 5 sets of 5 repetitions at 60% one-repetition maximum.	Other: Leg Press Resistance Training (5x5) Leg Press resistance training at 60% one-rep-max for five sets of five repetitions
Experimental: Controlled-tempo Resistance Training - 3x5 (CT3x5) The controlled-tempo group followed a metronome for both eccentric and concentric phases of the leg press with the intention of maintaining a steady three-second concentric and three-second eccentric. This group completed 3 sets of 5 repetitions at 60% one-repetition maximum.	Other: Leg Press Resistance Training (3x5) Leg Press resistance training at 60% one-rep-max for three sets of five repetitions
Experimental: Controlled-tempo Resistance Training - 5x5 (CT5x5) The controlled-tempo group followed a metronome for both eccentric and concentric phases of the leg press with the intention of maintaining a steady three-second concentric and three-second eccentric. This group completed 5 sets of 5 repetitions at 60% one-repetition maximum.	Other: Leg Press Resistance Training (5x5) Leg Press resistance training at 60% one-rep-max for five sets of five repetitions

Outcome Measures

Primary Outcome Measures

Quality-of-life [At baseline and Week 1, mid (Week 4), and post (Week 9), out of a total study duration of 9 weeks.]
Participant quality of life (measured through focus group questions & SF-36)

Secondary Outcome Measures

Balance [At baseline and Week 1, mid (Week 4), and post (Week 9), out of a total study duration of 9 weeks.]
Using the biodex to do a 3 x 20s double-foot eyes-open balance test on Level 6.
6-minute Walk Test [At baseline and Week 1, mid (Week 4), and post (Week 9), out of a total study duration of 9 weeks.]
A "brisk"-paced 6-minute walk test.
Timed-up-and-go [At baseline and Week 1, mid (Week 4), and post (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-Sit-to-Stand) [At baseline and Week 1, mid (Week 4), and post (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 [At baseline and Week 1, mid (Week 4), and post (Week 9), out of a total study duration of 9 weeks.]
Participants one-repetition max on leg press machine.
Body Mass Index [At baseline and Week 1, mid (Week 4), and post (Week 9), out of a total study duration of 9 weeks.]
Mass and height will be combined to report BMI in kg/m^2
Strength-to-mass Ratio [At baseline and Week 1, mid (Week 4), and post (Week 9), out of a total study duration of 9 weeks.]
Mass and Leg Press 1RM will be combined to calculate strength-to-mass ratio.
Leg press one-rep-max velocity pre-to-post [At baseline and Week 1, mid (Week 4), and post (Week 9), out of a total study duration of 9 weeks.]
Velocity (m/s) of leg press measured at post-intervention, using baseline one-rep-max.
