The impact of Dietary Weight loss, Aerobic Exercise, and Daylong Movement on Social Cognitive Mediators of Long-term Weight loss

Abstract

This report contrasts the impact of a dietary weight loss intervention (WL) paired with aerobic exercise (EX) and/or sitting less and moving throughout the day (SL) on self-efficacy for walking (hereafter walking self-efficacy) and satisfaction with physical functioning (hereafter satisfaction). Additional analyses examined dose-response associations between change in weight and changes in these key outcomes. Older adults (N = 112; age = 70.21 4.43) were randomized to 6 months of WL+EX, WL+SL, or WL+EX+SL followed by a 12-month maintenance period. All groups reported increases in walking self-efficacy at month 6 with greater improvements in WL+EX and WL + EX+SL. Only WL+SL demonstrated improved walking self-efficacy at month 18. All conditions demonstrated improved satisfaction scores at both time points. Changes in walking self-efficacy and satisfaction were negatively associated with change in weight over the 6-month intervention and after the maintenance period. These results support the utility of WL + SL for improving key social cognitive outcomes in aging.

Experimental study on physical intervention of Virtual Reality cycling on simple obese college students

“…The study recruited 41 college students (25 males and 16 females) from an university in the east region of China. Inclusion criteria required participants to be between 18 and 24 years old, have no self-reported diagnosed physical or mental disability, and uctuate within 5% of their weight in the past six months [10]. All participants provided informed consent before taking part in the experiment and were required to attend practice sessions at a designated time and place, with the option to ride at a gym or other location in case of special circumstances.…”
