Exercise interventions have small clinical benefits on  PA  levels in community-dwelling older adults , with a decline in the observed improvement after six months of the intervention cessation
Exercise is a form of physical activity ( PA ) .
PA is an important marker of health and quality of life in older adults .
The purpose of this study was to conduct a systematic review of the literature to assess the effect of exercise-based interventions on an at least six-month follow up PA measure , and to describe the specific strategies implemented during the intervention to strengthen the sustainability of PA in community-dwelling 65 + year-old adults .
Effect of Wearable Technology Combined With a Lifestyle Intervention on Long-term Weight Loss: The IDEA Randomized Clinical Trial.
Importance Effective long-term treatments are needed to address the obesity epidemic . Numerous wearable technologies specific to physical activity and diet are available , but it is unclear if these are effective at improving weight loss . Objective To test the hypothesis that , compared with a st and ard behavioral weight loss intervention ( st and ard intervention ) , a technology-enhanced weight loss intervention ( enhanced intervention ) would result in greater weight loss . Design , Setting , Participants R and omized clinical trial conducted at the University of Pittsburgh and enrolling 471 adult participants between October 2010 and October 2012 , with data collection completed by December 2014 . Interventions Participants were placed on a low-calorie diet , prescribed increases in physical activity , and had group counseling sessions . At 6 months , the interventions added telephone counseling sessions , text message prompts , and access to study material s on a website . At 6 months , participants r and omized to the st and ard intervention group initiated self-monitoring of diet and physical activity using a website , and those r and omized to the enhanced intervention group were provided with a wearable device and accompanying web interface to monitor diet and physical activity . Main Outcomes and Measures The primary outcome of weight was measured over 24 months at 6-month intervals , and the primary hypothesis tested the change in weight between 2 groups at 24 months . Secondary outcomes included body composition , fitness , physical activity , and dietary intake . Results Among the 471 participants r and omized ( body mass index [ BMI ] , 25 to < 40 ; age range , 18 - 35 years ; 28.9 % nonwhite , 77.2 % women ) , 470 ( 233 in the st and ard intervention group , 237 in the enhanced intervention group ) initiated the interventions as r and omized , and 74.5 % completed the study . For the enhanced intervention group , mean base line weight was 96.3 kg ( 95 % CI , 94.2 - 98.5 ) and 24-month weight 92.8 kg ( 95 % CI , 90.6- 95.0 ) [ corrected ] . For the st and ard intervention group , mean baseline weight was 95.2 kg ( 95%CI,93.0 - 97.3 ) and 24-month weight was 89.3 kg ( 95%CI , 87.1 - 91.5 ) [ corrected ] . Weight change at 24 months differed significantly by intervention group ( estimated mean weight loss , 3.5 kg [ 95 % CI , 2.6 - 4.5 } in the enhanced intervention group and 5.9 kg [ 95 % CI , 5.0 - 6.8 ] in the st and ard intervention group ; difference , 2.4 kg [ 95 % CI , 1.0 - 3.7 ] ; P = .002 ) . Both groups had significant improvements in body composition , fitness , physical activity , and diet , with no significant difference between groups . Conclusions and Relevance Among young adults with a BMI between 25 and less than 40 , the addition of a wearable technology device to a st and ard behavioral intervention result ed in less weight loss over 24 months . Devices that monitor and provide feedback on physical activity may not offer an advantage over st and ard behavioral weight loss approaches .
