Reduced heart rate variability (HRV) and fatigue are common after COVID-19 infection and both are potentially influenced by physical activity (PA). We compared resting HRV, PA from accelerometers and questionnaires, and self-reported fatigue in 41 COVID-19 survivors (~8 months postinfection, 38 ± 17 years) with 41 matched controls. Differences in HRV were observed on acceleration capacity (p = 0.041), deceleration capacity (p = 0.032), high-frequency peak frequency (p = 0.019), absolute low-frequency power (p = 0.042), relative very low-frequency power (p = 0.012), SD2 (from Poincare plot; p = 0.047), and DFA2 (slope of long-term …

Physical Function Across The Lifespan In Adults With Multiple Sclerosis: An Application Of The Short Physical Performance Battery, Brenda Jeng, Petra Šilić, Rachel E. Bollaert, Brian M. Sandroff, Robert W. Motl

Exercise Science Faculty Research and Publications

Background

Multiple sclerosis (MS) typically has its onset in early and middle adulthood, but the population is steadily becoming more dominated by older adults. One of the primary consequences of both MS and aging involves declines of lower extremity physical function and mobility. This cross-sectional study compared physical function status based on Short Physical Performance Battery (SPPB) summary and component scores between persons with MS and healthy controls across 6 age groups. We further examined associations between SPPB summary scores and component scores as well as associations between summary scores and measures of physical and cognitive function for identifying the …

Primary Results Of A Phase-Iii, Randomized Controlled Trial Of The Behavioral Intervention For Increasing Physical Activity In Multiple Sclerosis Project, Robert W. Motl, Ariel Kidwell, Brian M. Sandroff, Lara A. Pilutti, Gary R. Cutter, Roberto Aldunate, Rachel E. Bollaert

Exercise Science Faculty Research and Publications

Background

We undertook a phase-III, randomized controlled trial (RCT) that examined the effectiveness of a behavioral intervention based on social cognitive theory (SCT) and delivered through the Internet using e-learning approaches for immediate and sustained increases in physical activity among persons with multiple sclerosis (MS).

Method

The study followed a parallel group RCT design. Persons with MS (N = 318) were randomized into either behavioral intervention (n = 159) or attention/social contact control (n = 159) conditions. The conditions were administered over a 6-month period by persons who were uninvolved in screening, recruitment, random assignment, and outcome …

Randomized Controlled Trial Of The Behavioral Intervention For Increasing Physical Activity In Multiple Sclerosis Project: Secondary, Patient-Reported Outcomes, Robert W. Motl, Brian M. Sandroff, Lara A. Pilutti, Gary R. Cutter, Roberto Aldunate, Ariel Kidwell, Rachel E. Bollaert

Exercise Science Faculty Research and Publications

Background

We undertook a randomized controlled trial (RCT) that investigated the effectiveness of a theory-based, Internet-delivered, behavioral intervention focusing on physical activity promotion for immediate and sustained improvements in secondary, patient-reported outcomes (PROs) of function, symptoms, and quality of life (QOL) in multiple sclerosis (MS).

Method

Persons with MS (N = 318) were recruited from throughout the United States and randomized into behavioral intervention (n = 159) or attention/social contact control (n = 159) conditions. The conditions were administered over a 6-month period by persons who were uninvolved in screening, recruitment, random assignment, and outcome assessment. There …

Phase-Iii, Randomized Controlled Trial Of The Behavioral Intervention For Increasing Physical Activity In Multiple Sclerosis: Project Bipams, Robert W. Motl, Brian M. Sandroff, Brooks C. Wingo, Justin Mccroskey, Lara A. Pilutti, Gary R. Cutter, Rachel E. Bollaert, Edward Mcauley

Exercise Science Faculty Research and Publications

Background

We propose a phase-III, randomized controlled trial (RCT) that examines the effectiveness of a behavioral intervention based on social cognitive theory (SCT) and delivered through the Internet using e-learning approaches for increasing physical activity and secondary outcomes (e.g., symptoms) in a large sample of people with multiple sclerosis (MS) residing throughout the United States.

Methods/design

The proposed phase-III trial will use a parallel group, RCT design that examines the effect of a 6-month behavioral intervention for increasing physical activity and secondarily improving mobility, cognition, symptoms, and quality of life (QOL) in persons with MS. The primary outcome is accelerometer-measured …

Step Counts Of Non-White Minority Children And Youth By Gender, Grade Level, Race/Ethnicity, And Mode Of School Transportation, Tyler G. Johnson, Timothy A. Brusseau, Paul W. Darst, Pamela H. Kulinna, Janel White-Taylor

Kinesiology Faculty Publications and Presentations

Background: The purposes of this study were to describe and analyze the steps/d of nonwhite minority children and youth by gender, grade level, race/ethnicity, and mode of school transportation. A secondary purpose was to compare the steps/d of minority children and youth to their Caucasian grade-level counterparts. Methods: Participants were 547 minority youth grades 5 to 8 from 4 urban schools. Participants wore sealed pedometers for 6 consecutive week/school days. Three hundred and ten participants responded to a questionnaire concerning their mode of transportation to and from school. Results: Statistical analyses indicated a main effect for gender (F(3,546) …

Step Counts Of 10- To 11-Year-Old Children By Ethnicity And Metropolitan Status, Tyler G. Johnson, Timothy A. Brusseau, Susan Vincent Graser, Paul W. Darst, Pamela H. Kulinna

Kinesiology Faculty Publications and Presentations

Background: The purpose of this study was to conduct a secondary analysis by combining 2 pedometer data sets to describe and analyze pedometer-determined steps/day of children by ethnicity and metropolitan status.

Methods: Participants were 582 children (309 girls, 273 boys; 53% Hispanic, 26% Caucasian, 21% African American) age 10 to 11 years (M = 10.37 ± 0.48) attending 1 of 10 schools located in urban, suburban, and rural settings. Participants wore a research grade pedometer for at least 3 week/school days. Mean steps/ day were analyzed by gender, ethnicity, and metropolitan status.

Results: Statistical analyses indicated 1) boys (12,853 ± …

Impact Of Pedometer Use And Self-Regulation Strategies On Junior High School Physical Education Students' Daily Step Counts, Jane Shimon, Linda M. Petlichkoff

Kinesiology Faculty Publications and Presentations

Background: The aim of this study was to determine the impact of pedometer use and self-regulation strategies on adolescents’ daily physical activity.

Methods: Junior high school students (n = 113) enrolled in seventh- and eighth-grade physical education classes (52 girls, 61 boys) volunteered to participate in a 5-week study to assess daily step counts. Ten physical education classes were randomly assigned to 1 of 3 groups: (a) self-regulation, (b) open, and (c) control.

Results: A repeated-measures, mixed-model analysis of variance revealed a significant 3 × 4 (Group by Time) interaction effect, F_6,290 = 2.64, P < .02. Followup analyses indicated participants in the self-regulation group took 2071 to 4141 more steps/d than the control. No other significant differences emerged among groups on step counts.

Conclusions: It appears that …
