In the last few decades, the research focus in biomechanics has broadened substantially. With this diversity of focus, there have been many novel developments in new technologies used in biomechanics. Biomechanics has become an integral subdiscipline that has interfaced with several other areas in kinesiology and has contributed significantly to enhancing the knowledge base in all areas ...
Measuring Femoral Neck Loads In Healthy Young And Older Adults During Stair Ascent And Descent, 2021 Beijing Sport University
Measuring Femoral Neck Loads In Healthy Young And Older Adults During Stair Ascent And Descent, Chen Deng, Jason C. Gillette, Timothy R. Derrick
Understanding the hip loading environment for daily activities is useful for hip fracture prevention, rehabilitation, and the design of osteogenic exercises. Seventeen older adults (50–70 yrs) and twenty young adults (18–30 yrs) were recruited. A rigid body model combined with a musculoskeletal model was used to estimate lower extremity loading. An elliptical cross-section model of the femoral neck was used to estimate femoral neck stress during stair ascent and descent. Two peaks were identified in the stress curves, corresponding to the peaks in the vertical ground reaction force. During stair ascent, significantly higher tension on the superior femoral ...
Tibial Stress During Running Following A Repeated Calf‐Raise Protocol, 2020 University of Exeter
Tibial Stress During Running Following A Repeated Calf‐Raise Protocol, Hannah M. Rice, Megan Kenny, Matthew A. Ellison, Jon Fulford, Stacey A. Meardon, Timothy R. Derrick, Joseph Hamill
Abstract Tibial stress fractures are a problematic injury amongst runners. Increased loading of the tibia has been observed following prolonged weight‐bearing activity and is suggested to be the result of reduced activity of the plantar flexor muscles. The musculature that spans the tibia contributes to bending of the bone and influences the magnitude of stress on the tibia during running. Participant‐specific models of the tibia can be used as a non‐invasive estimate of tibial stress. This study aimed to quantify tibial stress during running using participant‐specific bone geometry and to compare tibial stress before and after ...
Transdisciplinary Approaches For The Dissemination Of The Switch School Wellness Initiative Through A Distributed 4-H/Extension Network, Gabriella Mcloughlin, Spyridoula Vazou, Laura C. Liechty, Ann R. Torbert, Lorraine Lanningham-Foster, R. R. Rosenkranz, Gregory Welk
Background: Schools provide an ideal setting for promoting healthy lifestyles in youth, but it has proven difficult to promote the adoption and implementation of evidence-based programming by school leaders. The SWITCH® (School Wellness Integration Targeting Child Health) intervention is a capacity-building process designed to help school leaders learn how to plan, implement, and sustain school wellness programs on their own.
Objective: The present study evaluates the transdisciplinary approaches used in establishing an integrated research-practice partnership with the state-wide 4-H/Extension network to support broader dissemination.
Method: The study used a mixed methods approach to evaluate the degree of engagement and ...

Associations Of Resistance Exercise With Cardiovascular Disease Morbidity And Mortality, 2019 East China Normal University
Associations Of Resistance Exercise With Cardiovascular Disease Morbidity And Mortality, Yanghui Lui, Duck-Chul Lee, Yehua Li, Weicheng Zhu, Riquan Zhang, Xuemei Sui, Carl J. Lavie, Steven N. Blair
Purpose: Resistance exercise (RE) can improve many cardiovascular disease (CVD) risk factors, but specific data on the effects on CVD events and mortality are lacking. We investigated the associations of RE with CVD and all-cause mortality and further examined the mediation effect of body mass index (BMI) between RE and CVD outcomes.
Methods: We included 12,591 participants (mean age, 47 yr) who received at least two clinical examinations 1987-2006. RE was assessed by a self-reported medical history questionnaire.
Results: During a mean follow-up of 5.4 and 10.5 yr, 205 total CVD events (morbidity and mortality combined) and ...
Evaluating Motivational Interviewing And Habit Formation To Enhance The Effect Of Activity Trackers On Healthy Adults’ Activity Levels: Randomized Intervention, Laura D. Ellingson, Jeni E. Lansing, Kathryn J. Deshaw, Karissa L. Peyer, Yang Bai, Maria Perez, L. Alison Phillips, Gregory Welk
Background: While widely used and endorsed, there is limited evidence supporting the benefits of activity trackers for increasing physical activity; these devices may be more effective when combined with additional strategies that promote sustained behavior change like motivational interviewing (MI) and habit development. Objective: This study aims to determine the utility of wearable activity trackers alone or in combination with these behavior change strategies for promoting improvements in active and sedentary behaviors. Methods: A sample of 91 adults (48/91 female, 53%) was randomized to receive a Fitbit Charge alone or in combination with MI and habit education for 12 ...
Comparative Effectiveness Of Aerobic, Resistance, And Combined Training On Cardiovascular Disease Risk Factors: A Randomized Controlled Trial, Elizabeth C. Schroeder, Warren D. Franke, Rick L. Sharp, Duck-Chul Lee
Although exercise has well-documented health benefits on cardiovascular disease (CVD), the benefit of combination exercise on CVD risk factors in individuals with elevated risk has not been fully elucidated. We compared the effects of aerobic, resistance, and a combination of both aerobic and resistance training on CVD risk factors including peripheral and central BP, cardiorespiratory fitness (CRF), muscular strength, body composition, blood glucose and lipids. Sixty-nine adults (58±7 years) with an elevated blood pressure or hypertension, overweight/obesity, and sedentary lifestyle were randomized to one of the three 8-week exercise programs or a non-exercise control group. Participants in all ...
Physical Activity And The Development Of Substance Use Disorders: Current Knowledge And Future Directions, 2018 Iowa State University
Physical Activity And The Development Of Substance Use Disorders: Current Knowledge And Future Directions, Angelique G. Brellenthin, Duck-Chul Lee
Physical activity and exercise are positive health behaviors that have been shown to reduce the risk of physical and psychological diseases. There is a strong rationale that physical activity could be a protective factor against the development of substance use disorders (SUDs), which include some of the most common mental health conditions such as tobacco and alcohol use disorder. This review examined the epidemiological literature to describe the associations of physical activity and substance use across the lifespan. The findings indicated that physical activity is positively associated with current and future alcohol use but negatively associated with tobacco and other ...

Fitness And Fatness As Health Markers Through The Lifespan: An Overview Of Current Knowledge, Francisco B. Ortega, Cristina Cadenas-Sanchez, Duck-Chul Lee, Jonatan R. Ruiz, Steven N. Blair, Xuemei Sui
There is an increasing body of evidence supporting that both fitness and fatness levels relate to current and future individuals’ health status. In this article, we discuss the meaning of fitness and fatness/obesity, and make an overview of what is currently known about fitness and fatness as potentially modifiable risk factors related to health and disease from preschool children to older adults. We describe the methods available for fitness assessment in each age group, providing reference/criterion values when available. Most of the existing previous reviews are focused on specific age groups with the advantage of allowing more in-depth ...
Running As A Key Lifestyle Medicine For Longevity, 2017 Iowa State University
Running As A Key Lifestyle Medicine For Longevity, Duck-Chul Lee, Angelique G. Brellenthin, Paul D. Thompson, Xuemei Sui, I-Min Lee, Carl J. Lavie
Running is a popular and convenient leisure-time physical activity (PA) with a significant impact on longevity. In general, runners have a 25%–40% reduced risk of premature mortality and live approximately 3 years longer than non-runners. Recently, specific questions have emerged regarding the extent of the health benefits of running versus other types of PA, and perhaps more critically, whether there are diminishing returns on health and mortality outcomes with higher amounts of running. This review details the findings surrounding the impact of running on various health outcomes and premature mortality, highlights plausible underlying mechanisms linking running with chronic disease ...
Resistance Training Improves Cardiovascular Health In Postmenopausal Women, 2016 Iowa State University
Resistance Training Improves Cardiovascular Health In Postmenopausal Women, Duck-Chul Lee, Elizabeth C. Schroeder
Evidence has been emerging on the importance of adding a muscle-strengthening component to regular physical activity to improve quality of life; delay the loss of muscle mass and function; and prevent osteoporosis, sarcopenia, and the falls, fractures, and disability that may follow.1 Menopause and aging may lead to a loss in fitness, decrease in muscle strength and bone mineral density, and a gain in weight, all of which concomitantly increase the risk for many chronic diseases, such as cardiovascular disease.2 If muscle-strengthening exercise can delay or prevent these diseases in postmenopausal women, this would have important public health ...
Associations Between Physical Activity And Obesity Defined By Waist-To-Height Ratio And Body Mass Index In The Korean Population, Duck-Chul Lee, On Lee, Sukha Lee, Yeon Soo Kim
This study investigated the associations between physical activity and the prevalence of obesity determined by waist-to-height ratio (WHtR) and body mass index (BMI).
This is the first study to our knowledge on physical activity and obesity using a nationally representative sample of South Korean population from The Korea National Health and Nutrition Examination Survey. We categorized individuals into either non-obese or obese defined by WHtR and BMI. Levels of moderate-to-vigorous physical activity were classified as ‘Inactive’, ‘Active’, and ‘Very active’ groups based on the World Health Organization physical activity guidelines. Multivariable logistic regression was used to examine the ...

Running And Mortality: Is More Actually Worse?, 2016 Iowa State University
Running And Mortality: Is More Actually Worse?, Duck-Chul Lee, Carl J. Lavie, Xuemei Sui, Steven N. Blair
In follow-up to our recent state-of-the-art review on running published in the November 2015 issue of Mayo Clinic Proceedings, 1 we have additional data regarding the relationship of high-dose running with prognosis. Clearly, observational studies have recently reported that leisure-time running provides mortality benefits. However, the dose-response relationship between running and mortality has been increasingly debated, specifically whether more running is better or worse.
Kinematic And Kinetic Indicators Of Sit-To-Stand, 2016 Des Moines University - Osteopathic Medical Center
Kinematic And Kinetic Indicators Of Sit-To-Stand, Catherine A. Stevermer, Jason C. Gillette
Variation in the timing indicators separating sit-to-stand (STS) into movement phases complicates both research comparisons and clinical applications. The purpose of this study was to use kinetic reference standards to identify accurate kinematic and kinetic indicators for STS movement analysis such that consistent indicators might be used for STS from varied initial postures. Healthy adults performed STS using 4 foot placements: foot-neutral, foot-back, right-staggered, and left-staggered. Kinetic and kinematic data were collected from force platforms and an 8-camera video system. Initiation, seat-off, vertical posture, and termination were detected with 5% start and 7.5% end thresholds for changes in kinetic ...

A Fit-Fat Index For Predicting Incident Diabetes In Apparently Healthy Men: A Prospective Cohort Study, Robert A. Sloan, Benjamin A. Haaland, Susumu S. Sawada, I-Min Lee, Xuemei Sui, Duck-Chul Lee, Yassine Ridouane, Falk Muller- Riemenschneider, Steven N. Blair
The purpose of this study was to examine the impact of combined cardiorespiratory fitness and waist-to-height ratio in the form of a fit-fat index on incident diabetes risk. Additionally, the independent predictive performance of cardiorespiratory fitness, waist-to-height ratio, and body mass index also were estimated and compared.
This was a prospective cohort study of 10,381 men who had a normal electrocardiogram and no history of major chronic disease at baseline from 1979 to 2005. Random survival forest models and traditional Cox proportional hazards models were used to predict diabetes at 5-, 10-, and 15-year incidence horizons.
