Objectives:

To evaluate the effect of a group-based Pilates training program on balance control and health status in healthy older adults.

Design:

A single-blind, randomized, controlled trial.

Setting:

General community.

Participants:

A total of 88 community-dwelling older adults (age 71.15 ± 4.30 years), without evidence of functional balance impairment, were recruited and allocated at random to a Pilates intervention group (n = 44) or a control group (n = 44).

Intervention:

The Pilates intervention group received 36 training sessions over three months (3 sessions a week), while the control group did not receive any intervention.

Outcome measures:

Standing upright postural stability, performance-based measures of balance, and self-reported health status was assessed in both groups at baseline and at the end of the intervention period.

Results:

Compared with the control group, the Pilates intervention did not improve postural stability, baseline functional measures of balance, or health status.

Conclusions:

The results suggest that because Pilates training is not task specific, it does not improve balance control or balance function in independent older adults.

Background:

This study explored multidimensional outcomes that were derived from the adherence to regular exercise among previously sedentary postmenopausal 45 to 64 years old women who engaged in a ~20-week exercise program.

Methods:

A randomized controlled trial with between-group (intervention and control women) and within-subject measures (baseline, postintervention, and 3-month and 12-month follow-ups) was conducted. HRQoL and several indicators of cardio-metabolic status and fitness were assessed.

Results:

After the intervention, the participants experienced a positive change in their short and long-term physical and mental health, with significant enhancements in several HRQoL dimensions, particularly mental well-being (23.3% of change) and menopause-related health and subdomains (17.0% of change) (P < .01). Improvements were maintained or continued (eg, mental well-being) overtime. These outcomes were accompanied by significant improvements in cardio-metabolic status and fitness, including weight, BMI, cardio-respiratory fitness and flexibility (up to 16.2% of change, P < .05). After the intervention, the intervention group exhibited better HRQoL than the control group at each of the measurement phases. Between-group differences were also observed for some indicators of cardiovascular health and flexibility.

Conclusions:

Our findings add evidence on the association of positive outcomes on HRQoL with improvements in cardio-metabolic health and fitness status after the adoption of an active lifestyle.

Background:

A cluster randomized controlled trial was conducted to assess the effectiveness of the Active Classrooms intervention, which integrates movement into academic lessons, on the moderate-to-vigorous physical activity levels (MVPA) of primary school children during class-time and throughout the school day.

Methods:

Ten classroom teachers and their students aged 8 to 12 years were recruited and randomized into the Active Classrooms intervention group (n = 131students, n = 5teachers) or a delayed-treatment controlled group (n = 117students, n = 5teachers). The intervention group participated in active academic lessons taught by the classroom teacher over an 8 week period. Accelerometers were used to gather physical activity data at baseline, postintervention and at 4 months follow-up. Teachers completed a questionnaire to evaluate the program.

Results:

A significant difference for change in daily class time MVPA levels was identified between the treatment (n = 95) and control (n = 91) groups from pre- to postintervention (P < .001) and this difference was maintained at follow-up (P < .001). No significant difference emerged between the treatment and control groups for change in school day MVPA levels from pre- to postintervention (P = .52) or follow-up (P = .09). Teachers reported that they were highly satisfied with the program.

Conclusions:

Movement integration has the potential to improve physical activity levels of primary school children in the classroom.

Background:

Little is known about factors that modify the effectiveness of exercise interventions in increasing exercise. We aimed to identify moderators of the effectiveness of aerobic exercise intervention in maintaining increased aerobic exercise among older individuals.

Methods:

The participants of a 4-year randomized controlled trial were a population sample of 1410 men and women aged 57 to 78 years. The aerobic exercise group included 185 individuals and the control group included 169 individuals who reported low aerobic exercise at baseline. Maintained increase in aerobic exercise was defined as at least 60-minute increase in moderate-to-heavy aerobic exercise per week from baseline to 2- and 4-year assessments.

Results:

Individuals in the aerobic exercise group were 2.5 (95% CI 1.5 to 3.9) times more likely to maintain increased aerobic exercise than those in the control group. Individuals aged < 68.5 years but not older individuals succeeded in maintaining increased aerobic exercise in the intervention group (P = .02 for interaction). Individuals who were past smokers (P = .02 for interaction), were working (P = .05 for interaction), or had symptoms of depression (P = .05 for interaction) succeeded better in maintaining increased aerobic exercise in the intervention group than other individuals.

Conclusions:

These findings help in more precise targeting of future exercise interventions among older individuals.

Background:

Physical activity is beneficial in several clinical situations and recommended for patients with ischemic heart disease, as well as for those undergoing cardiac surgery.

Methods:

In a randomized controlled trial, 34 patients underwent coronary artery bypass grafting. A randomized control group (n = 15) submitted to conventional physiotherapy. The intervention group (n = 19) received the same protocol plus additional aerobic exercise with cycle ergometer. Pulmonary function by spirometry, respiratory muscle strength by manovacuometry, and functional capacity through 6-minute walking test was assessed before surgery and at hospital discharge.

Results:

There was significant reduction in pulmonary function in both groups. In both groups, inspiratory muscle strength was maintained while expiratory muscle strength significantly decreased. Functional capacity was maintained in the intervention group (364.5 [324.5 to 428] vs. 348 [300.7 to 413.7] meters, P = .06), but it decreased significantly in control group patients (320 [288.5 to 393.0] vs. 292 [237.0 to 336.0] meters, P = .01). A significant difference in functional capacity was also found in intergroup analyses at hospital discharge (P = .03).

Conclusion:

Aerobic exercise applied early on coronary artery bypass grafting patients may promote maintenance of functional capacity, with no impact on pulmonary function and respiratory muscle strength when compared with conventional physiotherapy.
