The life quality, namely among aged population, has been widely studied. Observational data on behavioral context, especially regarding physical activity epidemiology, has shown efficiency in improving physical fitness with an impact on the dimensions of well-being. However, little research has been made regarding the impact of intervention on cardiorespiratory, strength, agility and quality of life, across different European contexts.

PURPOSE: we aimed to investigate the impact of exercise intervention on life quality, among elderly from 4 different European countries [Portugal (PT), Italy (IT), Bulgaria (BL) and Hungary (HU)].

METHODS: 364 (87 PT, 121 IT, 76 BL and 80 HU) older adults (68,9±6,3 yrs, 73,6±12,7 Kg, 1,61±0,08 m), male (26%) and female (74%), were recruited from local populations. Intervention program was based on 2 sessions/week (90 minutes each), supported on aerobic activities (40min), muscle strength (20min), body balance (10min), technical skill (10min) and stretching specific exercises (10 min). Pre (baseline assessment) and post one year intervention assessments were done on anthropometric measures, senior Fitness Test and EQ-5D-5L questionnaire, applied by trained technicians. ANOVA was performed to describe country’s group differences and the adaptations observed among different determinants, in pre and post intervention. When a significant interaction effect was detected post-hoc comparisons were performed with Bonferroni adjustment to identify the locations of the difference. Significance was set at p<0.05.

RESULTS: The effect of the time (one year intervention) were found to be significant, indicating changes on health determinants (hip-to-waist ratio, F = 13.895, p < 0.001; chair to stand, F = 20.314, p < 0.001; and handgrip muscle force, F = 21.023, p < 0.001), in all groups. However, Post-hoc analysis with Bonferroni adjustment indicated that the changes over the time were similar between country’s groups as the significance were maintained.

CONCLUSIONS: Context, country environment, seems have not influence on intervention output. Rather than country or geographical location, the intervention features may be the most important factor in increasing health status, by the associations with health determinants.
