Changes in life-style and function in 70-83-year-old subjects participating in a 1-year strength training programme

Research output: Contribution to journalArticle


Objective: To determine the changes in life-style (time and energy expenditure, EE, of physical activities) and function (leg extensors power and handgrip) in a group of 38 (19 M, 19 F) healthy elderly aged 70-83 years after a 1-year strength training programme. Design: Volunteers were assigned to a training (T, n.23) and to a control (C, n. 15) group according to a quasi-experimental design. Main outcome measures: Life-style: PA profile (type, time and EE). Function: leg extensors power (LEP) and handgrip (HG). Results: M showed higher PA time than F (15 vs. 7 h week-1, p = 0.02), and were engaged in higher intensity PA (cycling, gardening, sports) as F. F and C are more engaged in light-intensity (domestic and social-recreational) activities as M and T, respectively. Medium-high intensity PA time increased by 58% in T (p = 0.02). Light-intensity PA time increased by 76% in F (p = 0.02) and by 36% in C (p = 0.04). At baseline, M showed higher LEP (+ 89%) and HG (+ 65%) values than F (p <0.001). At end training, T showed a 11% increase in LEP (p = 0.001), whereas C showed a significant loss (- 5% LEP, - 8% HG, p <0.001). Trained females particularly increase LEP (+ 17%, p = 0.008). Conclusions: The 1-year training program was effective in improving life-style (PA) and functional abilities (LEP, HG) in healthy M and F elderly subjects.
