Cardiorespiratory Fitness Is Inversely Associated With Clustering Of Metabolic Syndrome Risk Factors: The Ball State Adult Fitness Program Longitudinal Lifestyle Study, Elizabeth Kelley, Mary T. Imboden, Matthew P. Harber, Holmes Finch, Leonard A. Kaminsky, Mitchell H. Whaley

Faculty Publications - Department of Kinesiology

Objective: The focus of this study was the association between the metabolic syndrome (MetSyn) and cardiorespiratory fitness (CRF) defined as maximal oxygen uptake (VO2max). Although previous research has shown a relationship between MetSyn and CRF, most studies are based on less objective measures of CRF and different cardiometabolic risk factor thresholds from earlier guidelines.

Validation Of Accelerometer-Based Energy Expenditure Prediction Models In Structured And Simulated Free-Living Settings, Alexander H. K. Montoye, Scott A. Conger, Christopher P. Connolly, Mary T. Imboden, M. Benjamin Nelson, Josh M. Bock, Leonard A. Kaminsky

This study compared accuracy of energy expenditure (EE) prediction models from accelerometer data collected in structured and simulated free-living settings. Twenty-four adults (mean age 45.8 years, 50% female) performed two sessions of 11 to 21 activities, wearing four ActiGraph GT9X Link activity monitors (right hip, ankle, both wrists) and a metabolic analyzer (EE criterion). Visit 1 (V1) involved structured, 5-min activities dictated by researchers; Visit 2 (V2) allowed participants activity choice and duration (simulated free-living). EE prediction models were developed incorporating data from one setting (V1/V2; V2/V2) or both settings (V1V2/V2). The V1V2/V2 method had the lowest root mean square …

Reference Standards For Lean Mass Measures Using Ge Dual Energy X-Ray Absorptiometry In Caucasian Adults, Mary T. Imboden, Ann M. Swartz, Holmes W. Finch, Matthew P. Harber, Leonard A. Kaminsky

Faculty Publications - Department of Kinesiology

Body composition assessments commonly focus predominantly on fat mass, however lean mass (LM) measurements also provide useful information regarding clinical and nutritional status. LM measurements help predict health outcomes and diagnose sarcopenia, which has been associated with frailty. Dual energy x-ray absorptiometry (DXA) is an established technique used in clinical and research settings to assess body composition including total and regional LM. Currently, there are no reference values available that were derived from GE-Healthcare DXA systems directly for US adults for LM, LM index (LMI), percent LM (% LM), and appendicular lean mass index (ALMI) and it is known that …

Reference Standards For Body Fat Measure Using Ge Dual Energy X-Ray Absorptiometry In Caucasian Adults, Mary T. Imboden, Whitney A. Welch, Ann M. Swartz, Alexander H. K. Montoye, Holmes W. Finch, Matthew P. Harber, Leonard A. Kaminsky

Faculty Publications - Department of Kinesiology

Background Dual energy x-ray absorptiometry (DXA) is an established technique for the measurement of body composition. Reference values for these variables, particularly those related to fat mass, are necessary for interpretation and accurate classification of those at risk for obesityrelated health complications and in need of lifestyle modifications (diet, physical activity, etc.). Currently, there are no reference values available for GE-Healthcare DXA systems and it is known that whole-body and regional fat mass measures differ by DXA manufacturer.

Objective To develop reference values by age and sex for DXA-derived fat mass measurements with GE-Healthcare systems.

Methods A de-identified sample of …

Critical-Thinking Skills Of First-Year Athletic Training Students Enrolled In Professional Programs, Dana K. Bates

Faculty Publications - Department of Kinesiology

Context: The Examination of Professional Degree Level document presented to the National Athletic Trainers’ Association Board of Directors states that research in athletic training education has not investigated differences in the critical-thinking skills of professional athletic training students.

Objective: Investigate the differences in critical thinking and other demographic variables across first-year athletic training students enrolled in professional bachelor’s- and master’s-degree programs.

Design: Quantitative study.

Setting: District 10 athletic training programs.

Patients or Other Participants: Students (N ¼ 40) enrolled within their first 6 months of a professional athletic training program were asked to complete the California Critical Thinking Skills Test …

Raw And Count Data Comparability Of Hip-Worn Actigraph Gt3x+ And Link Accelerometers, Alexander H. K. Montoye, M. Benjamin Nelson, Joshua M. Bock, Mary T. Imboden, Leonard A. Kaminsky, Kelly A. Mackintosh, Melitta A. Mcnarry, Karin A. Pfeiffer

Faculty Publications - Department of Kinesiology

To enable inter- and intrastudy comparisons it is important to ascertain comparability among accelerometer models.

Purpose: The purpose of this study was to compare raw and count data between hip-worn ActiGraph GT3X+ and GT9X Link accelerometers.

Methods: Adults (n = 26 (n = 15 women); age, 49.1 T 20.0 yr) wore GT3X+ and Link accelerometers over the right hip for an 80-min protocol involving 12–21 sedentary, household, and ambulatory/exercise activities lasting 2–15 min each. For each accelerometer, mean and variance of the raw (60 Hz) data for each axis and vector magnitude (VM) were extracted in 30-s epochs. …
