Impact of a community-based exercise programme on physical fitness in middle-aged and older patients with type 2 diabetes

Objectives: Physical fitness is related to all-cause mortality, quality of life and risk of falls in patients with type 2 diabetes. This study aimed to analyse the impact of a long-term community-based combined exercise program (aerobic + resistance + agility/balance + flexibility) developed with minimum and low-cost material resources on physical fitness in middle-aged and older patients with type 2 diabetes. Methods: This was a non-experimental pre-post evaluation study. Participants (N = 43; 62.92 ± 5.92 years old) were engaged in a community-based supervised exercise programme (consisting of combined aerobic, resistance, agility/balance and flexibility exercises; three sessions per week; 70 min per session) of 9 months' duration. Aerobic fitness (6-Minute Walk Test), muscle strength (30-Second Chair Stand Test), agility/balance (Timed Up and Go Test) and flexibility (Chair Sit and Reach Test) were assessed before (baseline) and after the exercise intervention. Results: Significant improvements in the performance of the 6-Minute Walk Test (Δ = 8.20%, p < 0.001), 30-Second Chair Stand Test (Δ = 28.84%, p < 0.001), Timed Up and Go Test (Δ = 14.31%, p < 0.001), and Chair Sit and Reach Test (Δ = 102.90%, p < 0.001) were identified between baseline and end-exercise intervention time points. Conclusions: A long-term community-based combined exercise programme, developed with low-cost exercise strategies, produced significant benefits in physical fitness in middle-aged and older patients with type 2 diabetes. This supervised group exercise programme significantly improved aerobic fitness, muscle strength, agility/balance and flexibility, assessed with field tests in community settings.

Psychometric properties of the Spanish version of the Coping Strategies Inventory (CSI) in older people

The aim of this study was to evaluate the psychometric properties of the Coping Strategies Inventory (CSI) in a sample of 243 people aged 55 to 99 years old. The first order factorial structure was similar to the structure of the original version of the CSI and to the Spanish adaptation with general population. Furthermore, high levels of internal consistency and of convergent validity were observed in the different primary scales. Nevertheless, the problem avoidance scale did not surpass the validity and reliability tests. Due to it we propose to delete two of the items of this scale. On the other hand, in this study we confirmed the secondary and tertiary structure obtained in the original version of the inventory that was neither confirmed in the Spanish adaptation study nor the other studies on the psychometric properties of the Spanish version of the CSI.
