No significant changes in any other health outcomes were found in either group .
Conclusion A pedometer-based walking program , incorporating a physical activity consultation , is effective in promoting walking and improving positive affect over 12 weeks in community based individuals .
Background Recent systematic review s have suggested that pedometers may be effective motivational tools to promote walking .
However , studies tend to be of a relatively short duration , with small clinical based sample s. Further research is required to demonstrate their effectiveness in adequately powered , community based studies .
Objective Using a r and omized controlled trial design , this study assessed the impact of a 12-week graduated pedometer-based walking intervention on daily step-counts , self-reported physical activity and health outcomes in a Scottish community sample not meeting current physical activity recommendations .
Long-term effects of varying intensities and formats of physical activity on participation rates, fitness, and lipoproteins in men and women aged 50 to 65 years.
BACKGROUND Although exercise parameters such as intensity and format have been shown to influence exercise participation rates and physiological outcomes in the short term , few data are available evaluating their longer-term effects . The study objective was to determine the 2-year effects of differing intensities and formats of endurance exercise on exercise participation rates , fitness , and plasma HDL cholesterol levels among healthy older adults . METHODS AND RESULTS Higher-intensity , group-based exercise training ; higher-intensity , home-based exercise ; and lower-intensity , home-based exercise were compared in a 2-year r and omized trial . Participants were 149 men and 120 postmenopausal women 50 to 65 years of age who were sedentary and free of cardiovascular disease . Recruitment was achieved through a r and om digit-dial community telephone survey and media promotion . All exercise occurred in community setting s. For higher-intensity exercise training , three 40-minute endurance training sessions per week were prescribed at 73 % to 88 % of peak treadmill heart rate . For lower-intensity exercise , five 30-minute endurance training sessions per week were prescribed at 60 % to 73 % of peak treadmill heart rate . Treadmill exercise performance , lipoprotein levels and other heart disease risk factors , and exercise adherence were evaluated at baseline and across the 2-year period . Treadmill exercise test performance improved for all three training conditions during year 1 and was successfully maintained during year 2 , particularly for subjects in the higher-intensity , home-based condition . Subjects in that condition also showed the greatest year 2 exercise adherence rates ( P < .003 ) . Although no significant increases in HDL cholesterol were observed during year 1 , by the end of year 2 subjects in the two home-based training conditions showed small but significant HDL cholesterol increases over baseline ( P < .01 ) . The increases were particularly pronounced for subjects in the lower-intensity condition , whose exercise prescription required more frequent exercise sessions per week . For all exercise conditions , increases in HDL cholesterol were associated with decreases in waist-to-hip ratio in both men and women ( P < .04 ) . CONCLUSIONS While older adults can benefit from initiating a regular regimen of moderate-intensity exercise in terms of improved fitness levels and small improvements in HDL cholesterol levels , the time frame needed to achieve HDL cholesterol change ( 2 years ) may be longer than that reported previously for younger population s. Frequency of participation may be particularly important for achieving such changes . Supervised home-based exercise regimens represent a safe , attractive alternative for achieving sustained participation
