120 min/week of neuromotor multicomponent training are enough to improve executive function and functional fitness in older women

Abstract

Purpose: The study aimed at comparing the effects of a neuromotor multicomponent training program (MCTP) on executive function, functional fitness, blood pressure, body composition and health-related quality of life (HRQOL), compared with a concurrent strength and endurance exercise training program (CONTROL-EXE) and a cognitive training program (CONTROL-COG).

Methods: 56 older women (73 ± 6 years) completed the 30-weeks intervention. The three groups attended two 60-min sessions per week and they were assessed before and after the intervention.

Results: MCTP showed a moderate improvement in Stroop C condition (28 ± 7 vs 32 ± 8 correct items; p = 0.001; d = 0.53) and Stroop interference score (-7.4 ± 7.3 vs -3.7 ± 6.1; p = 0.035; d = 0.55), while no changes were observed among control groups. MCTP showed a small to moderate improvement in Timed Up and Go test (TUGT) (5.85 ± 0.58 vs 5.46 ± 0.56 s; p < 0.001; d = 0.71) and Chair-Stand test (CST) (18 ± 4 vs 19 ± 4 repetitions; p < 0.001; d = 0.47); while CONTROL-EXE only improved moderately at TUGT (7.02 ± 1.1 vs 6.44 ± 0.91 s; p = 0.005; d = 0.59) and CONTROL-COG showed a moderate to small worsening in TUGT, CST and handgrip strength. Additionally, MCTP enhanced body composition and HRQOL. Lastly, both exercise groups showed lowered blood pressure values.

Conclusions: Our results suggest that a neuromotor MCTP could be considered as a highly suitable training to enhance executive function, functional fitness, HRQOL and body composition in older women.
