Background

Globally most children do not engage in enough physical activity. Day length and weather conditions have been identified as determinants of physical activity, although how they may be overcome as barriers is not clear. We aim to examine if and how relationships between children’s physical activity and weather and day length vary between countries and identify settings in which children were better able to maintain activity levels given the weather conditions they experienced.

Methods

In this repeated measures study, we used data from 23,451 participants in the International Children’s Accelerometry Database (ICAD). Daily accelerometer-measured physical activity (counts per minute; …

Triathlon Training For Women Breast Cancer Survivors: Feasibility And Initial Efficacy, Alex V. Ng, Alyson Cybulski, Ashley A. Engel, Paula E. Papanek, Megn A. Sheffer, Leslie J. Waltke, Judy A. Tjoe

Exercise Science Faculty Research and Publications

Exercise can improve quality of life (QOL) in breast cancer survivors. In contrast to many group or home-based exercise programs, little is known about the effectiveness of goal-oriented recreational activities.

Purpose

The purpose of this study was to evaluate a clinically overseen team triathlon training program on improving physiological and psychosocial health-related measures in female breast cancer survivors.

Methods

Twenty-three participants (age = 48 (8), BMI = 25 (1), mean (SE)) were recruited from a 14-week sprint triathlon (800-m swim, 20-km bike, 5-km run) team training program for women breast cancer survivors (4 (3) years post-surgery, chemo-, or radiation-therapy). Training …

Naturally-Occurring Changes In Social-Cognitive Factors Modify Change In Physical Activity During Early Adolescence, Rod K. Dishman, Marsha Dowda, Kerry L. Mciver, Ruth P. Saunders, Russell R. Pate

Faculty Publications

Purpose

To determine whether naturally-occurring changes in children’s motives and beliefs are associated with the steep decline in physical activity observed from childhood to early adolescence.

Methods

Latent growth modeling was applied in longitudinal tests of social-cognitive influences, and their interactions, on physical activity in a large cohort of boys and girls evaluated annually between 5th and 7th grades.

Results

Measurement equivalence of motives and beliefs was confirmed between boys and girls. After adjustment for gender and maturity differences, physical activity declined less in children who reported the least decreases in self-efficacy for overcoming barriers to activity and perceived parental …

Implementing Exercise In Cancer Care: Study Protocol To Evaluate A Community-Based Exercise Program For People With Cancer, Prue Cormie, Stephanie Lamb, Robert Newton, Lani Valentine, Sandy Mckiernan, Nigel Spry, David Joseph, Dennis Taaffe, Christopher M. Doran, Daniel A. Galvão

Research outputs 2014 to 2021

Background

Clinical research has established the efficacy of exercise in reducing treatment-related side-effects and increasing wellbeing in people with cancer. Major oncology organisations have identified the importance of incorporating exercise in comprehensive cancer care but information regarding effective approaches to translating evidence into practice is lacking. This paper describes the implementation of a community-based exercise program for people with cancer and the protocol for program evaluation.

Methods/Design

The Life Now Exercise program is a community-based exercise intervention designed to mitigate and rehabilitate the adverse effects of cancer and its treatment and improve physical and psychosocial wellbeing in people with cancer. …

Using Wireless Pedometers To Measure Children’S Physical Activity: How Reliable Is The Fitbit Zip?, Tingting Xu, Erik Jon Byker, Monica Rae Gonzales

Faculty Publications

The purpose of this study is to examine the reliability of wireless pedometers in measuring elementary school children’s physical activity. Activity measurement using a wireless pedometer Fitbit Zip^TM was compared to activity measurement using Yamax Digi-Walker^TM SW701 for a group of randomly selected 25 children in Grades 3, 4, and 5. Fitbit Zip^TM wireless pedometers were found to have an appropriate degree (Nunnally & Bernstein, 1994) of accuracy and reliability compared to the Yamax Digi-Walker^TM SW701 pedometer. The Fitbit Zip^TM wireless pedometer collected more step counts than the Yamax Digi-Walker^TM SW701 pedometer; however, the …

Vitamin D Status And Bone Mineral Density In Female Collegiate Dancers And Cheerleaders, Tara Sue Kenny, Damon Mccune, Laura J. Kruskall, James Navalta, John C. Young

Kinesiology and Nutrition Sciences Faculty Publications

Bone mineral density reflects an athlete’s cumulative history of energy availability, physical activity, and menstrual status, as well as nutritional and environmental factors. Although sports with high-impact loading are associated with higher bone mineral density than low-impact or non-impact sports, confounding variables are differences in the athletes’ body size and sport-specific training. The purpose of this study was to determine if bone mineral density (BMD) and vitamin D status are different between two groups of female collegiate athletes who have comparable body size/weight requirements, but who engage in qualitatively different training regimens. Full body, spine and dual femur BMD was …
