Dietary Weight Loss Advice In Us Health Magazines And Its Relation To Ancestral Diet, Risa J. Stein, Marium A. Choudhry, Thomas J. Murray Jr.

Journal of Evolution and Health

As rates of overweight and obesity have risen in the US, the public has sought effective strategies for weight loss through dietary modification. A proliferation of processed foods and changing governmental nutrition guidelines have both impacted dietary intake patterns. While physicians are considered respectable sources of weight-loss information, increasingly the public has turned to the media, particularly magazines, for weight loss advice. This study investigated the dietary recommendations found in the five leading US health-related magazines and compared those recommendations to ancestral diets. With a couple notable exceptions, leading health magazines present consistent recommendations for dietary modifications to promote weight ...

Effects Of Static Stretching On Squat Performance In Division I Female Athletes, Clare F. Heisey, J. Derek Kingsley

International Journal of Exercise Science

International Journal of Exercise Science 9(3): 359-367, 2016. Static stretching was once recognized as a method of preparation for physical activity that would inhibit performance and increase risk of injury. However, a growing body of research suggests that static stretching may not have an inhibitory effect. Regardless, the data have not examined gender differences or the fatigue index (FI) and flexibility effects of static stretching on the back squat over multiple sets. Therefore, the purpose of this study was to examine the relationship between a static-stretch condition (SC) and control condition (CC) on flexibility and the FI of Division ...

Individual Differences In The Programming Of Rapid Bimanual Movements: Are Two Modes Better Than One?, Ashley N. Vander Does, David E. Sherwood

International Journal of Exercise Science

International Journal of Exercise Science 9(3): 347-358, 2016. One of the challenges in performing simultaneous bimanual movements is to prevent interference from one limb to the other, thereby maintaining spatial accuracy in both limbs. Prior research has shown that when a longer distance movement is performed with a shorter movement, the shorter movement overshoots its target and the longer movement undershoots its target relative to control conditions where two shorter or two longer movements are made. The current experiment investigated the motor control strategies used by participants when performing simultaneous aiming movements combining both different and same distances. Participants ...

In this study, we evaluated the construct and predictive validity of psychosocial correlates of television viewing in a population of African American (AA) breast cancer survivors (BCS).

Methods: AA BCS (N = 342, Mean age = 54 years) completed measures of decisional balance, self-efficacy, family support, and time spent watching television online. Exploratory structural equation modeling (ESEM) was used to examine the construct and predictive validity as well as the differential item functioning of the instruments among population ...


Habitual Exercise Instigation (Vs. Execution) Predicts Healthy Adults’ Exercise Frequency, L. Alison Phillips, Benjamin Gardner 2016 Iowa State University

Habitual Exercise Instigation (Vs. Execution) Predicts Healthy Adults’ Exercise Frequency, L. Alison Phillips, Benjamin Gardner

L. Alison Phillips

Objective: Habit is thought to be conducive to health behavior maintenance, because habits prompt behavior with minimal cognitive resources. The precise role of habit in determining complex behavioral sequences, such as exercise, has been underresearched. It is possible that the habit process may initiate a behavioral sequence (instigation habit) or that, after instigation, movement through the sequence is automated (execution habit). We hypothesized that exercise instigation habit can be empirically distinguished from exercise execution habit and that instigation habit strength is most predictive of future exercise and reflective of longitudinal exercise behavior change. Further, we evaluated whether patterned exercise action ...
