How The Foot Modulates Its Mechanics During Uphill And Downhill Walking, Jeffrey M. Patterson, Kota Z. Takahashi 2019 Department of Biomechanics

How The Foot Modulates Its Mechanics During Uphill And Downhill Walking, Jeffrey M. Patterson, Kota Z. Takahashi

Student Research and Creative Activity Fair

The foot's biomechanical role in walking on sloped surfaces is currently unclear. While previous biomechanics studies have examined the hip, knee, and ankle, the foot is oversimplified as a rigid-body segment. This oversimplification overshadows its complex structure and function. In this project, we use an innovative multi-segment foot model to explore how the foot adapts its mechanics to incline and decline walking. Preliminary results have revealed that the foot is capable of adapting its mechanical work profile to both incline and decline walking. Specifically, the foot can increase its positive work output (i.e., increased energy generation) during inclined ...

The Effects Of Swimming Training On Arterial Stiffness, Muscular Strength And Cardiorespiratory Endurance In Postmenopausal Women With Stage 2 Hypertension, Steven Scott

Student Research and Creative Activity Fair

Objective:

Aging is associated with progressive decreases in arterial health and function as well as overall fitness. It is crucial to prevent or reduce the negative effects of aging on vasculature and fitness components by implementing appropriate lifestyle interventions, such as exercise training. We examined the effects of a swimming (SWM) regimen on arterial stiffness (pulse wave velocity, PWV), blood pressure (BP), wave reflection (AIx), muscle strength and aerobic capacity in postmenopausal women with stage 2 hypertension.

Methods:

Using a parallel experimental design, participants were randomly assigned to either a SWM (n=52) or non-exercising control group (n=48) for ...


Influence Of Hip Abductor Fatigue On Acl Loading During Single-Leg Landing, Namwoong Kim 2019 University of Nebraska at Omaha

Influence Of Hip Abductor Fatigue On Acl Loading During Single-Leg Landing, Namwoong Kim

Student Research and Creative Activity Fair

A musculoskeletal simulation study is necessary to identify the cause-effect relationship between hip abductor weakness and ACL loading during athletic events such as landing and jumping. The purpose of this study was to identify the effect of weakness of hip abductors on lower extremity kinematics and ACL loading during single-leg landings. We hypothesized that hip abductor weakness would alter lower extremity joint kinematics. We also hypothesized that hip abductor weakness would increase ACL loading during single-leg landings. This study was a combination of a human experiment and a musculoskeletal modeling simulation. Ten healthy participants performed single-leg landing from a height ...

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 ...


An Examination Of The Severity Of Aquatic Incidents, Lyndsey K. Lanagan-Leitzel 2019 Eastern Connecticut State University

An Examination Of The Severity Of Aquatic Incidents, Lyndsey K. Lanagan-Leitzel

International Journal of Aquatic Research and Education

Lanagan-Leitzel (2012) found that lifeguards do not consistently report incidents when free-viewing aquatic scenes and miss some incidents that should be considered critical. This could have been because they did not know what incidents were critical to monitor or because they were busy monitoring other incidents. In the current study, lifeguards and non-lifeguards were presented with video clips of isolated incidents and rated the severity of each on a scale of 0 – 7. The lifeguards reported greater mean and maximum incident severity than non-lifeguards. Further analyses of lifeguard responses revealed that severity ratings were only moderately correlated to the report ...

Examining The Perceived Impacts Of Recreational Swimming Lessons For Children With Autism Spectrum Disorder, Erin Kraft M.A. Ed.

International Journal of Aquatic Research and Education

The purpose of this study was to examine the perceived impacts of recreational swimming lesson participation for children with Autism Spectrum Disorder (ASD). Although swimming lessons are a suitable form of physical activity for children with ASD, minimal research has examined the impacts of these lessons. The author conducted semi-structured interviews with an Applied Behaviour Analysis (ABA) certified therapist and a swim instructor, each with experience working with children with ASD in swimming lessons. The participants suggested that swimming lessons encouraged children with ASD to socialise. Both participants agreed that distractions in swimming lessons and barriers in communication created challenges ...


Impact Of Psychological And Physical Stressors On The Exercise-Induced Immune Response In Collegiate Swimmers, Connor Alexander Kuremsky 2019 Louisiana State University and Agricultural and Mechanical College

Impact Of Psychological And Physical Stressors On The Exercise-Induced Immune Response In Collegiate Swimmers, Connor Alexander Kuremsky

LSU Master's Theses

Evidence suggests high-intensity exercise training increases incidence of upper respiratory infection in young-adult athletes (Spence et al. 2007). Collegiate athletes experience chronic stress, which has been shown to result in increased proportions of late-differentiated CD8+ T-cells of a dysfunctional phenotype (Bosch et al. 2009). However, many studies fail to consider possible moderators such as psychological stress and cytomegalovirus (CMV) infection. Purpose: To examine the impact of psychological stress, CMV infection, and exercise on proportions of early- and late-differentiated CD4+ and CD8+ T-cells in collegiate swimmers over a 7-month training period. Methods: Data were collected from NCAA Division 1 swimmers (13 ...

Exercise Science Faculty Publications

Cluster set loading in the back squat: Kinetic and kinematic implications. J Strength Cond Res XX(X): 000–000, 2018—As athletes become well trained, they require greater stimuli and variation to force adaptation. One means of adding additional variation is the use of cluster loading. Cluster loading involves introducing interrepetition rest during a set, which in theory may allow athletes to train at higher absolute intensities for the same volume. The purpose of this study was to investigate the kinetic and kinematic implications of cluster loading as a resistance training programming tactic compared with traditional loading (TL). Eleven resistance-trained ...

The purpose of this study was to examine the effects of a ballistic or non-ballistic concentric-only bench press (COBP) on subsequent plyometric push-up performance. Fourteen resistance trained men completed two separate one-repetition-maximum (1RM) testing sessions followed by three randomized experimental explosive push-up sessions. These sessions combined a heavy concentric bench press with plyometric push-ups. Using a series of 3 × 10 (condition × time) repeated measures ANOVA, comparisons were made between the effects of ballistic and non-ballistic bench presses on performance of plyometric push-ups to investigate push-up performance variables. Compared with the control condition, both ballistic and non-ballistic bench presses produced lower ...


Drowning Prevention: Define And Then Gather Evidence Or Gather Evidence To Define?, Nina J. Nyitrai, Suzi Edwards, Nicholas O'Dwyer 2018 University of Newcastle Australia

Drowning Prevention: Define And Then Gather Evidence Or Gather Evidence To Define?, Nina J. Nyitrai, Suzi Edwards, Nicholas O'Dwyer

International Journal of Aquatic Research and Education

According to the World Health Organization, drowning fatalities are a neglected public health issue ranked as the third most frequent cause of unintentional death by injury. Data used to record drowning incidents are acknowledged as inaccurate. Recommendations on drowning prevention based on these data are currently not informed by accurate, detailed and reliable evidence. Two modifications to current practice are proposed: 1) an Aquatic Incident Report needs to be developed as an extension of the current workplace incident report to prompt for information commonly not included in current drowning reports; and 2) National Water Safety Plans should be modified to ...

Autophagy And Aging: Maintaining The Proteome Through Exercise And Caloric Restriction, Kurt A. Escobar, Nathan H. Cole, Christine M. Mermier, Trisha A. Vandusseldrop

Faculty Publications

Accumulation of dysfunctional and damaged cellular proteins and organelles occursduring aging, resulting in a disruption of cellular homeostasis and progressive degen-eration and increases the risk of cell death. Moderating the accrual of these defunctcomponents is likely a key in the promotion of longevity. While exercise is knownto promote healthy aging and mitigate age‐related pathologies, the molecular under-pinnings of this phenomenon remain largely unclear. However, recent evidencessuggest that exercise modulates the proteome. Similarly, caloric restriction (CR), aknown promoter of lifespan, is understood to augment intracellular protein quality.Autophagy is an evolutionary conserved recycling pathway responsible for thedegradation, then turnover of ...
