Objective: The efficacy of effort appraisal exercise action plans was tested among underactive and inactive university students (N = 221). Methods: Students were randomized across three conditions (information, action planning, or realistic effort action planning (REAP)) and participated in psychoeducational small-group sessions. Students returned…

The novel coronavirus may impact exercise habits of those with intellectual disabilities. Due to the mandated discontinuation of face-to-face research, investigators must adapt projects to protect all involved while collecting objective physical activity metrics. This brief report outlines a modification process of research methods to adhere to…

Body fat (BF) and body mass index (BMI) that including physical fitness with health is important to protect and improve to the health. The aim of this study is to examine the effects of exercise preferences on BMI, body fat according to by self-report. A total of 442 volunteers, including 180 female and 262 male participated in the study. Body…

This study examined (a) the validity of two accelerometers (ActiGraph GT3X [ActiGraph LLC, Pensacola, FL, USA] and activPAL [PAL Technologies Ltd., Glasgow, Scotland]) for the assessment of sedentary behavior; and (b) the variations in assessment accuracy by setting minimum sedentary bout durations against a proxy for direct observation using an…

Affective responses to physical activity are assumed to play a role in exercise initiation and maintenance. The Physical Activity Affect Scale measures four dimensions of an individual's affective response to exercise. Group differences in the interpretation of scale items can impact the interpretability of mean differences, underscoring the need…

Perceived exertion scales, based on subjective perception of energy output, are gaining respect as prescribing and monitoring tools for individual exercise programs. A review of recent literature indicates growing research interest in applications for individuals who are elderly, inactive, or subject to medical conditions such as angina. (IAH)

Two studies are presented which deal with reliability and validity of self-reports of aerobic activity. The goal of these studies was to develop and test a form that could be used in a behavior modification program designed to increase aerobic activity among healthy families. (Author/DF)

Examines measures of children's perspectives on physical activity, focusing on the Children's Attitudes toward Physical Activity Scale and other measurement approaches. The article identifies current measurement issues and makes five recommendations for assisting in the development of useful research instruments. (SM)

Valid measurement of physical activity is important for studying the risks for morbidity and mortality. The purpose of this study was to examine evidence of construct validity of two similar single-response items assessing physical activity via self-report. Both items are based on the stages of change model. The sample was 687 participants (men =…
