Abstract 637: Effects Of A 12-Week Physical Training Program On Cardiovascular Risk Factors And Quality Of Life In Elderly Women
Background: Physical activity (PA) and the consequently lower cardiorespiratory fitness levels in older adults decline with age and are associated with cardiovascular disease events and mortality. In the present study we aimed at evaluating the effectiveness of a 12-week supervised physical training community-based program on cardiovascular risk factors and health-related quality of life (HRQoL) in elderly women.
METHODS: An exercise intervention was conducted as a prospective, longitudinal and controlled study in 30 elderly participants. Intervention consisted of an individually designed group-based PA program thrice a week (aerobic exercise, resistance training and stretching exercises for 1 h each time), for a period of 12 weeks. The following cardiovascular risk data were investigated: blood pressure, triglycerides, HDL, glycaemia, body mass index (BMI) and waist circumference. HRQoL was evaluated with the Short Form-36 (SF-36).
RESULTS: Mean age was 69 ± 0.9 years, normotensive (63% with controlled hypertension), BMI was 25 ± 0.7 kg/m2 and waist circumference was 89 ± 1.6 cm. The exercise group prevented the significant HDL decrease that occurred in the sedentary group (HDL increase: 2.5 [95%CI -4.4 to 9.4] vs HDL decrease: -9.2 [95%CI -16.2 to -2.2], p< 0.01). There was also a significant improvement in the SF-36 subscales in PA but not sedentary group: physical functioning score (increase of 24.2 [95%CI 11.8 to 36.5] vs. -9.2 [95%CI -21.5 to 3.2], p< 0.001), physical role functioning score (increase of 35.4 [95%CI 12.8 to 58.0] vs. 16.7 [95%CI -6.0 to 39.3], p< 0.01) and general health score (increase of 23.7 [95%CI 36.9 to 10.4] vs. 2.4 [95%CI -10.9 to 15.7], p< 0.001).
CONCLUSIONS: This study shows that a 12-week physical training program may significantly improve cardiovascular risk reduction, physical capacity, physical function and general health scores.
