How Does Maximal Aerobic Capacity Predict The Performance Of Rotc Cadets On The Acft, Ruth Larson, Annika Grams, Sofia Harman, Sara Thomasson, Kaitlyn Wabakken, Katelynn Brock, Payton Price, Anthony Acevedo, Zachary Zeigler
International Journal of Exercise Science: Conference Proceedings
The Army Combat Fitness Test (ACFT) is a newly developed test that assesses the combat readiness of U.S. Army soldiers. Maximal aerobic capacity (VO2max) characteristics vary between soldiers and have the ability to affect performance outcomes. The purpose of this cross-sectional study is to determine if VO2max can predict performance outcomes of the ACFT in ROTC cadets. Methods: ROTC cadets (44 males, 15 females; aged 21.06 ± 3.6 years) completed the 6-event ACFT (3-repetition maximum trap-bar deadlift [MDL], standing power toss [SPT], hand-release pushups [HRPU], sprint-drag-carry shuttle run [SDC], plank [PLK], and 2-mile run [2MR]). The cadets …

Novel Application Of A Performance Prediction Model During Altered Running Gait Strategies, Oluchi Ibe, Robert Musci, Jenevieve L. Roper
International Journal of Exercise Science: Conference Proceedings
Currently, there is limited research demonstrating that gait retraining can significantly impact running economy and subsequent running performance in distance runners with most of the research showing no or minimal change. Recently, a novel model was developed that predicts running performance based on changes in running economy but has not previously been applied when altering running gait strategies. PURPOSE: The goal of the study was to determine the effect of altering running strategy on predicted running performance in distance runners through application of this novel prediction model. METHODS: Fifteen male (n=10; Age: 22.2 ± 4.9 years; Height: 177.7 ± 7.4 …

Assessing The Validity Of A Performance Prediction Model For Use With Gait Retraining, Christian Faltas, Robert Musci, Jenevieve L. Roper
International Journal of Exercise Science: Conference Proceedings
A common strategy that athletic trainers and high-performance athletes use to manage and treat running-related injuries is gait retraining. However, the research is equivocal on how gait retraining can affect running economy and subsequent running performance in distance runners. A new prediction model was developed that predicts running performance based on oxygen consumption changes, however, it is unclear if this model is valid and can accurately be used to predict running performance as a result of gait retraining. PURPOSE: The goal of the study was to determine the validity of the performance prediction model, particularly when applied to gait …

Sled-Pull Training Improves Maximal Horizontal Velocity In Collegiate Male And Female Soccer Players, Atithi K. Multani, John A. Brasher, Robert J. Rovetti, Junyuan Lin, Robert V. Musci, Jenevieve L. Roper
International Journal of Exercise Science: Conference Proceedings
The force velocity profile (FvP), which details the capacity to sprint and accelerate, is a determinant of success in soccer. To date, no data exist that details the FvP of male and female collegiate Division I soccer players. Further, there is limited insight on how training interventions may modify the FvP of either males or females. PURPOSE: The aim of this investigation was to compare FvP between collegiate male and female athletes and assess the efficacy of a 12-week sled pull training intervention. METHODS: 17 male (20.17 ± 1.38 yrs) and 12 female (19.75 ± 1.05 yrs) soccer …

Critical speed (CS) is the speed one can sustain while maintaining blood lactate, phosphocreatine, and oxygen uptake levels. “Distance capacity beyond CS” (D’) is the reserve an athlete can draw from to run faster than their CS. By increasing CS and D’, athletes can sustain a faster threshold pace (CS) and have a greater sprint capacity (D’). Unlike distance traveled and speed, which do not reflect the metabolic strain of an exercise, CS and D’ assess the relative intensity of an activity to provide individualized inter- and intra-competition insight. PURPOSE: This investigation evaluated CS and D’ among men and women …

There can be differences in fatigue characteristics between men and women. In some cases, these differences may be manifested in unique strength responses in the fatigued and non-fatigued limbs following a unilateral fatiguing task. PURPOSE: This study examined changes in maximal voluntary isometric contraction (MVIC) force following dominant (Dm) and nondominant (NDm) unilateral, isometric handgrip holds to failure (HTF) for the exercised ipsilateral (IPS) and non-exercised contralateral (CT) limbs. Sex- and hand- (Dm vs NDm) dependent responses in HTF time, performance fatiguability (PF, %D in MVIC) for the exercised IPS limb, as well as changes in MVIC force for the …
Effect Of Treadmill Surface Stiffness On The Running Economy Benefits Of A Highly-Cushioned Racing Shoe: A Pilot Study, Zane A. Thornton, Dustin P. Joubert
Effect Of Treadmill Surface Stiffness On The Running Economy Benefits Of A Highly-Cushioned Racing Shoe: A Pilot Study, Zane A. Thornton, Dustin P. Joubert
International Journal of Exercise Science: Conference Proceedings
Running economy (RE) is defined as the oxygen consumption (VO2) at a given running speed. The Nike Vaporfly line of racing shoes, which includes more compliant and resilient midsole foam and a carbon-fiber plate, have been shown to improve RE during treadmill testing. Previous research suggests that RE in general is worse on treadmills with stiffer running platforms. However, it is unclear if the magnitude of the RE benefits provided by these new shoes relative to a control shoe differ based on treadmill stiffness. Given that some treadmill platforms allow more flex or compliance, this may be an …
The Effect Of Sport-Specific Resistance Training On Athletic Performance Outcomes Of College Rodeo Athletes, Kenneth L. Bowen Jr.
The Effect Of Sport-Specific Resistance Training On Athletic Performance Outcomes Of College Rodeo Athletes, Kenneth L. Bowen Jr.
International Journal of Exercise Science: Conference Proceedings
Resistance training yields significant improvements to athletic performance outcomes among multiple sports. A sport-specific approach for resistance produces greater adaptation and transfer to various sports. However, few studies have examined the potential benefit of sport-specific resistance training for the sport of rodeo. PURPOSE: The aim of the current investigation was to assess the effect of sport-specific resistance training on athletic performance outcomes of rodeo athletes. METHODS: Seventeen college rodeo athletes (12 females; 5 males) participated in an 8-week, 3-days per week, sport-specific resistance training program. Muscle cross sectional area (CSA), mid-thigh pull maximal isometric voluntary contraction (MVC), height (HT), …
