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 …

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 VO2max in adolescents. Twenty-two healthy, asymptomatic adolescents performed …

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) …

International Journal of Exercise Science
International Journal of Exercise Science 11(4): 1063-1073, 2018. The purpose of this study was to investigate the relationships between tests incorporated into a physical assessment battery (PAT) for a law enforcement (LEA) to determine if there were redundancies (i.e. tests measuring the same qualities). A retrospective analysis of 226 recruits (196 males, 30 females) was conducted. The PAT consisted of: maximal push-ups and sit-ups completed in 60 s; a 75-yard pursuit run (75PR); maximal revolutions completed on an arm ergometer in 60 s; and a 2.4 km run. A one-way ANOVA (p<0.05) determined if there were significant differences in the PAT data between the sexes. Pearson’s correlations (p<0.05) calculated relationships between each of the tests within the PAT, and males and females were analyzed separately. Further, tests that could potentially measure similar qualities, including upper-body endurance (push-ups/arm ergometer), abdominal endurance (push-ups/sit-ups), and aerobic fitness (arm ergometer/2.4 km run) were investigated further with one-sample t-tests to determine agreement. Males performed better than the females in all tests (p≤0.017). There were significant correlations …

Reestablishing A Culture Of Water Competency At An Hbcu, Knolan C. Rawlins
Reestablishing A Culture Of Water Competency At An Hbcu, Knolan C. Rawlins
International Journal of Aquatic Research and Education
African American children ages 5 – 19 years drown in swimming pools at rates of 5.5 times higher than those of whites (Gilchrist & Parker, 2014). Literature suggested culture is the culprit for this disparity. A fear of water dates to slavery (Pitts, 2007). After slavery was abolished, the memory of drowning remained part of the African American culture. In the twentieth century, the popularity of swimming grew with the increase in public pools. The era of the Jim Crow laws kept African Americans out of public pools (Pitts, 2007). Although the political landscape has shifted since the Jim Crow …

The Effect Of Repeated Heat Stress On Mitochondrial Protein Content In Human Skeletal Muscle, Amy Twitchell, Robert Hyldahl
The Effect Of Repeated Heat Stress On Mitochondrial Protein Content In Human Skeletal Muscle, Amy Twitchell, Robert Hyldahl
Journal of Undergraduate Research
Exercise has been known to improve mitochondrial function and increase its content in muscle. However, those who suffer from certain diseases such as Chronic Obstructive Pulmonary Disease (COPD) and Type II Diabetes often experience concomitant exercise intolerance. In vitro research suggests that the application of a mild heat stress may be sufficient to activate some of the same signaling proteins that become active during exercise, possibly leading to mitochondrial biogenesis in skeletal muscle. However, this has not yet been confirmed to occur in human skeletal muscle. Therefore, the purpose of this study was to investigate the effect of heat therapy …
