MI vs. CT OAP Complete Dataset
This study investigated low-dose resistance training (RT) on quality of life (QoL), functional capacity, and strength in untrained older adults. Thirty-one participants were randomised into four groups to perform a leg press exercise at maximal-intent (MI) or controlled-tempo (CT) RT across two volumes (3×5 or 5×5, sets × repetitions) at 60% 1RM once weekly for six weeks. QoL was assessed through body mass, BMI, SF-36, and a three-month follow-up survey. Functional capacity was evaluated using balance, 6-minute walk (6MWT), timed-up-and-go (TUG), and 30-second sit-to-stand (30sSTS) tests. Strength was measured via leg press 1RM, maximum voluntary isometric contractions (MVIC), and strength-to-mass ratio. Assessments were conducted at pre-, mid-, and post-intervention to evaluate 3 versus 6 weeks efficacy. Significant improvements were observed in SF-36 (p ≤ 0.05, for significant findings), functional capacity (average p = 0.0011), and strength (average p = 0.001) across all groups. CT showed greater strength improvements (p < 0.05), versus MI’s greater functional capacity enhancements (p < 0.05). Both 3×5 and 5×5 were effective with no significant superiority, indicating success regardless of volume. These findings support the efficacy of low-dose RT and highlight the potential for further research.
