Temporal Trends In The Handgrip Strength Of 2,592,714 Adults From 14 Countries Between 1960 And 2017: A Systematic Analysis, Trevor J. Dufner, John S. Fitzgerald, Justin J. Lang, Grant R. Tomkinson

Education, Health & Behavior Studies Faculty Publications

Background: Handgrip strength (HGS) is an excellent marker of functional capability and health in adults, although little is known about temporal trends in adult HGS.

Objectives: The aim of this study was to systematically analyze national (country-level) temporal trends in adult HGS, and to examine relationships between national trends in adult HGS and national trends in health-related and socioeconomic/demographic indicators.

Methods: Data were obtained from a systematic search of studies reporting temporal trends in HGS for adults (aged ≥20 years) and by examining national fitness datasets. Trends in mean HGS were estimated at the country-sex-age group level by best-fitting …

Reliability Of The Styku 3d Whole Body Scanner For The Assessment Of Body Size In Athletes, Joe D. Derouchey, Grant R. Tomkinson, Jesse L. Rhoades, John S. Fitzgerald

Education, Health & Behavior Studies Faculty Publications

Anthropometry is important for predicting sport performance. While 3-dimensional (3D) body scanners increase the feasibility of anthropometric assessment, reliability data on athletes are lacking. The aim of this study was to determine the test-retest reliability of a portable, single-camera 3D body scanning system (Styku S100) to assess circumferences, and whole-body and segmental surface areas and volumes of athletes. Forty-nine (19 male) athletes were scanned six times (two sessions of three scans). The Styku scanner demonstrated nearly perfect reliability. Systematic errors were negligible (mean standardized bias [95%CI]: scan 1 vs. 4, 0.04 [0.02, 0.06]), random errors were negligible (mean standardized typical …

Temporal Trends In 6-Minute Walking Distance For Older Japanese Adults Between 1998 And 2017, Grant R. Tomkinson, Tetsuhiro Kidokoro, Trevor Dufner, Shingo Noi, John S. Fitzgerald, Holly M. Brown-Borg

Education, Health & Behavior Studies Faculty Publications

Background

The 6-minute walking distance (6MWD) is an excellent measure of both functional endurance and health. The primary aim of this study was to estimate temporal trends in 6MWD for older Japanese adults between 1998 and 2017; the secondary aim was to estimate concurrent trends in body size (i.e., height and mass) and self-reported participation in exercise/sport.

Methods

Adults aged 65–79 years were included. Annual nationally representative 6MWD data (n = 103,505) for the entire period were obtained from the Japanese Ministry of Education, Culture, Sports, Science and Technology. Temporal trends in means (and relative frequencies) were estimated at …

Criterion-Referenced Mcaft Cut-Points To Identify Metabolically Healthy Cardiorespiratory Fitness Among Adults Aged 18–69 Years: An Analysis Of The Canadian Health Measures Survey, Emily Wolfe Phillips, Deepa P. Rao, Leonard A. Kaminsky, Grant Tomkinson, Robert Ross, Justin J. Lang

Education, Health & Behavior Studies Faculty Publications

Objective: This study aimed to develop and validate health-related criterion-referenced cutpoints for the modified Canadian Aerobic Fitness Test (mCAFT), a field-based measure to predict cardiorespiratory fitness (CRF) among adults (18–69 years). Methods: Criterionreferenced mCAFT cut-points were developed using nationally representative data from cycles 1 (2007–09) and 2 (2009–11) of the Canadian Health Measures Survey (CHMS). Receiver operating characteristic curves were used to identify age- and sex-specific cut-points for measured waist circumference, blood pressure, and high-density lipoprotein. Cut-points were validated against metabolic syndrome using a fasted sub-sample (n=1,093) from cycle 5 (2016– 17). Results: 4,967 participants (50% women) were retained for …

Sleeping Time Is Associated With Functional Limitations In A National Sample Of Older Americans, Brenda M. Vincent, Nathaniel Johnson, Grant R. Tomkinson, Ryan Mcgrath, Brian C. Clark, Bong-Jin Choi

Education, Health & Behavior Studies Faculty Publications

Background: Engaging in healthy behaviors may help to preserve function during aging; however, it is not well understood how sleeping time is associated with functional capacity in older adults.

Aims: We sought to determine the association of sleeping time on functional limitation in a national sample of older Americans.

Methods: The analytical sample included 6,020 adults aged at least 65 years who participated in the 2007-2016 waves of the National Health and Nutrition Examination Survey. Respondents indicated their hours of sleep/week night and were categorized as <5, 5-6.5, 7-8, 8.5-9, and >9 hours of sleep/week night. Ability to complete 19 functional tasks …

Test-Retest Reliability Of Trimp In Collegiate Ice Hockey Players, Jason G. Ulmer, Grant R. Tomkinson, Sandra E. Short, Martin Short, John S. Fitzgerald

Education, Health & Behavior Studies Faculty Publications

The utility of the heart rate derived variable TRaining IMPulse (TRIMP) for assessing internal training load in ice hockey players is not clear. Having a reliable measure of internal training load during on-ice training sessions would help coaches program exercise training. This study determined the reliability of TRIMP during on-ice training sessions in ice hockey players. Twelve Division I collegiate male ice hockey players (aged 18–23 years) had their heart rate (HR) data recorded during two on-ice practice sessions separated by two weeks. TRIMP and other descriptive HR variables were compared between sessions. TRIMP demonstrated moderate reliability during on-ice sessions. …

The 20-M Shuttle Run: Assessment And Interpretation Of Data In Relation To Youth Aerobic Fitness And Health, Grant R. Tomkinson, Justin J. Lang, Joel Blanchard, Luc A. Léger, Mark S. Tremblay

Education, Health & Behavior Studies Faculty Publications

Cardiorespiratory fitness (CRF) is a good summative measure of the body’s ability to perform continuous, rhythmic, dynamic, large-muscle group physical activity, and exercise. In children, CRF is meaningfully associated with health, independent of physical activity levels, and it is an important determinant of sports and athletic performance. Although gas-analyzed peak oxygen uptake is the criterion physiological measure of children’s CRF, it is not practical for population-based testing. Field testing offers a simple, cheap, practical alternative to gas analysis. The 20-m shuttle run test (20mSRT)—a progressive aerobic exercise test involving continuous running between 2 lines 20 m apart in time to …
