Mechanical ventilation (MV) is a life-saving intervention for many critically ill patients. Unfortunately, prolonged MV results in rapid diaphragmatic atrophy and contractile dysfunction, collectively termed ventilator-induced diaphragm dysfunction (VIDD). Recent evidence reveals that endurance exercise training, performed prior to MV, protects the diaphragm against VIDD. While the mechanism(s) responsible for this exercise-induced protection against VIDD remain unknown, increased diaphragm antioxidant expression may be required. To investigate the role that increased antioxidants play in this protection, we tested the hypothesis that elevated levels of the mitochondrial antioxidant enzyme superoxide dismutase 2 (SOD2) is required to achieve exercise-induced protection against VIDD. Cause …

Kinesiology and Health Science Faculty Publications
The purpose of the present study was to examine the relationships between neuromuscular function and functional balance performance in firefighters. Fifty career firefighters (35.1±7.5yr) performed isometric leg extension and flexion muscle actions to examine peak torque (PT), and absolute (aTQ) and normalized (nTQ; %PT) rapid torque variables at 50, 100, 150, and 200ms. A performance index (PI) was determined from the functional balance assessment completion time. Partial correlations were used to examine the relationship between the PI and the maximal and rapid TQ variables for each muscle and the composite value, while controlling for demographic data related to the PI. …

Linking Gait Dynamics To Mechanical Cost Of Legged Locomotion, David V. Lee, Sarah L. Harris
Life Sciences Faculty Research
For millenia, legged locomotion has been of central importance to humans for hunting, agriculture, transportation, sport, and warfare. Today, the same principal considerations of locomotor performance and economy apply to legged systems designed to serve, assist, or be worn by humans in urban and natural environments. Energy comes at a premium not only for animals, wherein suitably fast and economical gaits are selected through organic evolution, but also for legged robots that must carry sufficient energy in their batteries. Although a robot's energy is spent at many levels, from control systems to actuators, we suggest that the mechanical cost of …

Background: Cancer cachexia occurs in approximately 80% of cancer patients and is a key contributor to cancer-related death. The mechanisms controlling development of tumour-induced muscle wasting are not fully elucidated. Specifically, the progression and development of cancer cachexia are underexplored. Therefore, we examined skeletal muscle protein turnover throughout the development of cancer cachexia in tumour-bearing mice. Methods: Lewis lung carcinoma (LLC) was injected into the hind flank of C57BL6/J mice at 8 weeks age with tumour allowed to develop for 1, 2, 3, or 4 weeks and compared with PBS injected control. Muscle size was measured by cross-sectional area analysis …

Effects Of Opaque, Weighted Bottles On Maternal Sensitivity And Infant Intake, Alison K. Ventura, Alexandra Hernandez
Kinesiology and Public Health
Caregivers' abilities to assess how much is in the bottle may lead to encouragement of infant bottle emptying and overfeeding. The present study assessed whether use of opaque, weighted bottles (as compared with conventional, clear bottles) improves feeding outcomes. Mothers with infants <32 weeks of age (n = 76) were assessed on two separate days. Mothers fed their infants from an opaque, weighted bottle on 1 day and a clear bottle on the other; conditions were counterbalanced. Blinded raters certified in the Nursing Child Assessment Feeding Scale scored all videos to determine maternal sensitivity. Infant intake was assessed by weighing the bottle before and …

Orderliness Of Visual Stimulus Motion Mediates Sensorimotor Coordination, Joshua L. Haworth, Nicholas Stergiou
Journal Articles
We explored the coupling of gaze and postural sway to the motion of a visual stimulus, to further understand sensorimotor coordination. Visual stimuli consisted of a horizontally oscillating red dot, moving with periodic (sine), chaotic, or aperiodic (brown noise) temporal structure. Cross Recurrence Quantification Analysis (cRQA) was used to investigate the coupling between each measured signal with the time series of the visual stimulus position. The cRQA parameter of percent determinism indicated similar strength of coupling of gaze with either periodic or chaotic motion structures, yet weaker coupling to aperiodic stimulus motion. The cRQA parameter of Maxline indicated a particular …

On The Choice Of Multiscale Entropy Algorithm For Quantification Of Complexity In Gait Data, Peter C. Raffalt, William Denton, Jennifer M. Yentes
Journal Articles
The present study aimed at identifying a suitable multiscale entropy (MSE) algorithm for assessment of complexity in a stride-to-stride time interval time series. Five different algorithms were included (the original MSE, refine composite multiscale entropy (RCMSE), multiscale fuzzy entropy, generalized multiscale entropy and intrinsic mode entropy) and applied to twenty iterations of white noise, pink noise, or a sine wave with added white noise. Based on their ability to differentiate the level of complexity in the three different generated signal types, and their sensitivity and parameter consistency, MSE and RCMSE were deemed most appropriate. These two algorithms were applied to …
The Role Of Inflammation And Immune Cells In Blood Flow Restriction Training Adaptation: A Review,

The Role Of Inflammation And Immune Cells In Blood Flow Restriction Training Adaptation: A Review, Fabrício Eduardo Rossi, Marcelo Conrado De Freitas, Nelo Eidy Zanchi, Fábio Santos Lira, Jason M. Cholewa
Kinesiology
Blood flow restriction (BFR) combined with low-intensity strength training has been shown to increase skeletal muscle mass and strength in a variety of populations. BFR results in a robust metabolic stress which is hypothesized to induce muscle growth via increased recruitment of fast-twitch muscle fibers, a greater endocrine response, and/or enhancing the cellular swelling contribution to the hypertrophic process. Following exercise, neutrophils are the first immune cells to initiate the tissue remodeling process via several mechanisms including an increased production of cytokines and recruitment of monocytes/macrophages, which facilitate the phagocytosis of foreign particles, the differentiation of myoblasts, and the formation …

On The Calculation Of Sample Entropy Using Continuous And Discrete Human Gait Data, John D. Mccamley, William Denton, Peter C. Raffalt, Jennifer M. Yentes
Journal Articles
Sample entropy (SE) has relative consistency using biologically-derived, discrete data >500 data points. For certain populations, collecting this quantity is not feasible and continuous data has been used. The effect of using continuous versus discrete data on SE is unknown, nor are the relative effects of sampling rate and input parameters m (comparison vector length) and r(tolerance). Eleven subjects walked for 10-minutes and continuous joint angles (480 Hz) were calculated for each lower-extremity joint. Data were downsampled (240, 120, 60 Hz) and discrete range-of-motion was calculated. SE was quantified for angles and range-of-motion at all sampling rates and multiple combinations …

A Study Into The Reliability Of The Data Flow From Gps Enabled Portable Fitness Devices To The Internet, Philip Shambrook, Patrick J. Lander, Olivia Maclaren
International Journal of Exercise Science
International Journal of Exercise Science 11(7): 1184-1193, 2018. The growth in availability and affordability of portable fitness devices (PFDs) has facilitated a concomitant growth in the collection and sharing of what are assumed to be reliable measures of exercise and physical activity. This data is increasingly used by fitness trainers to track performance progression, and plan training. Whilst the reliability and validity of these devices has been reported, investigation into the variance in the data at different access points is less well examined. The aim of this study was to investigate the reliability of the data flow from global positioning …

Stride-To-Stride Fluctuations In Transtibial Amputees Are Not Affected By Changes In Push-Off Mechanics From Using Different Prostheses, Chase G. Rock, Shane R. Wurdeman, Nikolas Stergiou, Kota Z. Takahashi
Journal Articles
Stride-to-stride fluctuations of joint kinematics during walking reflect a highly structured organization that is characteristic of healthy gait. The organization of stride-to-stride fluctuations is disturbed in lower-limb prosthesis users, yet the factors contributing to this difference are unclear. One potential contributor to the changes in stride-to-stride fluctuations is the altered push-off mechanics experienced by passive prosthesis users. The purpose of our study was to determine if changes in push-off mechanics affect stride-to-stride fluctuations in transtibial amputees. Twenty-two unilateral transtibial amputees were enrolled in the 6- week cross-over study, where High and Low Activity (based on the Medicare Functional Classification System) …

Effects Of Changing The Focus Of Attention On Accuracy, Acceleration, And Electromyography In Dart Throwing, Dakota R. Hitchcock, David E. Sherwood
International Journal of Exercise Science
International Journal of Exercise Science 11(1): 1120-1135, 2018. Research over the past 15 years or so has shown that an external focus on the effects of one’s movements improves performance relative to an internal focus of attention on bodily actions. More recent research has attempted to discover how the focus of attention (FOA) influences underlying motor control processes by using kinematic and EMG measures. Research has shown that an external FOA reduces EMG activity and the co-contraction between agonist and antagonist muscle groups relative to an internal FOA. The primary goal of the current study was to determine how the …

Effects Of Variable Resistance Training On Kinetic And Kinematic Outcomes During A Heavy Conventional Deadlift, Timothy J. Gerking
Masters Theses & Specialist Projects
Variable Resistance Training (VRT), loading elastic band tension on a barbell, has shown improvements in force, power, and velocity. Studied extensively in the squat and bench press, VRT is less researched in the context of the deadlift. Additionally, while no acute VRT deadlift studies exist where intensity was ≥ 90% 1- RM, some heavy VRT studies suggest that at approximately 90% 1-RM, less band tension (BT) is required to enhance force and power than seen at lower intensities in existing research. Therefore, the purpose of this study was to determine the effects of VRT on peak relative vertical ground reaction …

This study investigated the effect of branched-chain amino acid (BCAA) supplementationon recovery from eccentric exercise. Twenty males ingested either a BCAA supplement or placebo(PLCB) prior to and following eccentric exercise. Creatine kinase (CK), vertical jump (VJ), maximalvoluntary isometric contraction (MVIC), jump squat (JS) and perceived soreness were assessed.No significant (p> 0.05) group by time interaction effects were observed for CK, soreness, MVIC, VJ,or JS. CK concentrations were elevated above baseline (p< 0.001) in both groups at 4, 24, 48 and 72 hr,while CK was lower (p= 0.02) in the BCAA group at 48 hr compared to PLCB. Soreness increasedsignificantly from baseline (p< 0.01) in both groups at all time-points; however, BCAA supplementedindividuals reported less soreness (p< 0.01) at the 48 and 72 hr time-points. MVIC force outputreturned to baseline levels (p> 0.05) at 24, 48 and 72 hr for BCAA individuals. No significant differencebetween groups (p> 0.05) was detected for VJ or JS. BCAA supplementation may mitigate musclesoreness following muscle-damaging …
