Background: Although aerobic exercise has been shown to improve the glycemic control of individuals with type 2 diabetes, a simple and effective approach to manage post-meal glycemic control remains less clear.
Purpose: This study examined the effect of 15-minute of post-meal aerobic exercise on the glycemic control and anxiety scores as compared with control trials in participants with and without type 2 diabetes.
Methods: Six adults volunteered to participate in the study (3 adults with type 2 diabetes, age = 44.33 ± 7.71; and 3 adults without type 2 diabetes, age = 31.67 ± 15.76). All participants received aerobic exercise intervention and control treatments. The aerobic exercise treatment was listening to upbeat music and dancing for 15-minutes, whereas the control participants ingested 1 gram of vitamin C 30-minutes post-meal. Glucose levels were measured at baseline, and the 10, and 15-minute mark in both exercise intervention and control conditions 30-minutes post-meal.
Results: There was a significant interaction between treatment and time on the change in glucose levels (P<0.001). There was a significant mean difference in change in glucose levels between exercise intervention and control conditions (P = 0.002). Change in glucose levels in exercise intervention was significantly decreased at 10-minute (-18 ± 4.35 vs. 1.67 ± 4.34, P = 0.009) and 15-minute (-24 ± 4.88 vs. 5.67 ± 4.88, P = 0.001) compared with control condition. Although there were no statistical differences in state anxiety scores between pre- and post-exercise intervention (p=0.42), there was a significant trend in the reduction of state anxiety scores in diabetic participants, as compared with healthy participants, after 15-minute exercise intervention (-8 vs. -1).
Conclusion: Aerobic exercise for 15-minute by dancing to music after a meal is an effective approach to controlling the blood glucose levels in type 2 diabetic and healthy persons.
Background
The transition from the home to college is a phase in which emerging adults shift toward more unhealthy eating and physical activity patterns, higher body mass indices, thus increasing risk of overweight/obesity. Currently, little is understood about how changing friendship networks shape weight gain behaviors. This paper describes the recruitment, data collection, and data analytic protocols for the SPARC (Social impact of Physical Activity and nutRition in College) study, a longitudinal examination of the mechanisms by which friends and friendship networks influence nutrition and physical activity behaviors and weight gain in the transition to college life.
Methods
The SPARC study aims to follow 1450 university freshmen from a large university over an academic year, collecting data on multiple aspects of friends and friendship networks. Integrating multiple types of data related to student lives, ecological momentary assessments (EMAs) are administered via a cell phone application, devilSPARC. EMAs collected in four 1-week periods (a total of 4 EMA waves) are integrated with linked data from web-based surveys and anthropometric measurements conducted at four times points (for a total of eight data collection periods including EMAs, separated by ~1 month). University databases will provide student card data, allowing integration of both time-dated data on food purchasing, use of physical activity venues, and geographical information system (GIS) locations of these activities relative to other students in their social networks.
Discussion
Findings are intended to guide the development of more effective interventions to enhance behaviors among college students that protect against weight gain during college.
