Agreement Among Six Methods Of Predicting The Anaerobic Lactate Threshold In Elite Cross-Country Skiers, Sean L. Carter, Ian Newhouse

International Journal of Exercise Science

International Journal of Exercise Science 12(2): 155-172, 2019. The anaerobic lactate threshold (LTan) is used to prescribe training intensity and measure endurance capacity. The LTan identifies a critical point where small increases in workload result in large increases in blood lactate concentration. LTan is usually predicted through visual inspection of a blood lactate (bLa) vs workload plot. Numerous other methods for predicting LTan exist, and the literature lacks a consensus regarding validity of prediction methods. The purpose of this study was to assess the agreement among visual inspection (VI), maximum distance (Dmax) and modified maximum distance (Dmod) from the lactate …

The Effects Of Ankle Braces On Lower Extremity Electromyography And Performance During Vertical Jumping: A Pilot Study, Zachariah J. Henderson Mr., Paolo Sanzo, Carlos Zerpa, Derek Kivi

International Journal of Exercise Science

International Journal of Exercise Science 12(1): 15-23, 2019. Ankle braces have been hypothesized to prevent ankle injuries by restricting range of motion (ROM) and improving proprioception at the ankle. As such, ankle braces are commonly worn by physically active individuals to prevent ankle injuries. Despite their widespread use, the effects that ankle braces have on athletic performance measures, such as vertical jumping, remains unclear. Furthermore, although ankle braces are known to restrict normal ROM at the ankle, little is known about the effects that ankle braces have on the lower extremity proximal to the ankle, specifically muscular activation. Therefore, the …

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 …

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 …
