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 …

Muscle Adaptations To High-Load Training And Very Low-Load Training With And Without Blood Flow Restriction, Matthew B. Jessee, Samuel L. Buckner, J. Grant Mouser, Kevin T. Mattocks, Scott J. Dankel, Takashi Abe, Zachary W. Bell, John P. Bentley, Jeremy P. Loenneke

Faculty Scholarship

An inability to lift loads great enough to disrupt muscular blood flow may impair the ability to fatigue muscles, compromising the hypertrophic response. It is unknown what level of blood flow restriction (BFR) pressure, if any, is necessary to reach failure at very low-loads [i.e., 15% one-repetition maximum (1RM)]. The purpose of this study was to investigate muscular adaptations following resistance training with a very low-load alone (15/0), with moderate BFR (15/40), or with high BFR (15/80), and compare them to traditional high-load (70/0) resistance training. Using a within/between subject design, healthy young participants (n = 40) performed four …

Neighborhood Socioeconomic Environment And Its Influence On Cardiorespiratory Fitness And Physical Activity In Youth, Morgan N. Clennin

Theses and Dissertations

Among youth, inadequate cardiorespiratory fitness and physical inactivity are powerful markers of health associated with numerous health outcomes across the lifespan. Unfortunately, a majority of U.S. youth have inadequate cardiorespiratory fitness levels and do not meet physical activity guidelines. While previous research has identified several individual-level factors associated with youth cardiorespiratory fitness and physical activity, environmental factors have been increasingly recognized. Of particular interest is the neighborhood socioeconomic environment, which has been consistently associated with several health outcomes among adults. However, little is known regarding the relationship between the neighborhood socioeconomic environment, cardiorespiratory fitness, and physical activity among younger populations. …

The Predictability Of Peak Oxygen Consumption Using Submaximal Ratings Of Perceived Exertion In Adolescents, Danilo V. Tolusso, Ward C. Dobbs, Michael Esco

International Journal of Exercise Science

International Journal of Exercise Science 11(4): 1173-1183, 2018. Rating of perceived exertion (RPE) extrapolation involves mathematically extending the submaximal relationship between RPE and oxygen consumption (VO₂) to maximal intensity. This technique allows practitioners to forego, potentially dangerous, maximal exertion testing while attaining accurate measures of maximal oxygen consumption used for exercise prescription. This method has been proven accurate in adults, but much less in known when applied to an adolescent population. The purpose of this study was to assess the accuracy of the RPE extrapolation as method for estimating VO_2max in adolescents. Twenty-two healthy, asymptomatic adolescents performed …

Characterizing The Aerobic And Anaerobic Energy Costs Of Polynesian Dances, Wei Zhu, David E. Lankford, Joel Reece, Daniel P. Heil

International Journal of Exercise Science

International Journal of Exercise Science 11(4): 1156-1172, 2018. This study characterized both aerobic and anaerobic energy expenditure (EE) for several Polynesian dances in a group of experienced professional Polynesian dancers. Thirteen men and 17 women were tested using indirect calorimetry to assess aerobic EE (and converted to METs), and fingertip blood lactate to estimate anaerobic EE, during both resting and dancing activities. Total EE was then computed as the sum of both aerobic and anaerobic activity energy expenditure (AEE, or EE above resting). One sample t-tests compared mean MET values for each type of dance to the 3-MET and 6-MET …

Foot-To-Foot Bioelectrical Impedance, Air Displacement Plethysmography, And Dual Energy X-Ray Absorptiometry In Resistance-Trained Men And Women, Justin Merrigan, Sina Gallo Phd, Jennifer Fields, Margaret T. Jones Phd

International Journal of Exercise Science

International Journal of Exercise Science 11(4): 1145-1155, 2018. Accurate assessment of body composition is important to athletic performance goal setting and nutritional program design. Dual-energy x-ray absorptiometry (DXA) is considered the “gold standard” in body composition assessment, yet the cost renders DXA unfeasible for many. Therefore, it is of interest to compare other body composition assessment methods to DXA in resistance-trained individuals whose focus is athletic performance. The purpose of the current study was to determine the agreement in estimates of body composition ((body fat (BF%); fat mass (FM); fat free mass (FFM)) by bioelectrical impedance analysis (BIA; Tanita SC-331S) …

The Influence Of Tissue Plasminogen Activator I/D Polymorphism On The Tpa Response To Exercise, Adam M. Coughlin

International Journal of Exercise Science

International Journal of Exercise Science 11(3): 1136-1144, 2018. The purpose was to determine if the Alu-insertion (I)/deletion (D) polymorphism of the tissue plasminogen activator (tPA) gene influences the tPA response to maximal exercise. Fifty male subjects (age = 23.6 ± 4.7 yrs) completed a maximal treadmill exercise test. Blood samples were drawn before and immediately after exercise for determination of plasma tPA antigen and activity. Isolated DNA was amplified via polymerase chain reaction, electrophoresed, and visually amplified to determine tPA genotype. Subjects were classified as possessing the D allele (D) (n = 28) or being homozygous for the I allele …

Effects Of Stretching Vs. Self-Myofascial Release On Ankle, Hip, And Shoulder Flexion, Trent S. Edwards

Student Theses and Dissertations

Deficits in range of motion can hinder performance, lead to more issues and prohibit some individuals from doing basic, everyday tasks. Stretching is one way people attempt to increase their range of motion. Self- myofascial release is a newer way of achieving increases in range of motion. Self-Myofascial Release (SMR) has been shown to increase ROM (Blandpied & Dorfman, 2014). However, use of a foam roller produced suboptimal SMR due to inadequate pressure on the roller (Evans, 2014). One solution to this problem would be to create additional pressure using a smaller, more targeted device of denser material. The current …
