International Journal of Exercise Science

International Journal of Exercise Science 11(4): 785-796, 2018. To successfully complete specialist police selection, officers must be physically fit. The aim of this study was to investigate the relationship between performance on selected anthropometric and fitness tests and successful selection into a specialist police unit. Thirty-two male police officers (mean age = 29.48±4.99 years) participated in a Barrier Fitness Assessment (BFA), followed by a Specialist Selection Course (SSC). The BFA spanned two consecutive days of testing (pull-ups, push-ups, seven-stage sit-ups, a timed loaded pack march, a Multi-Stage Fitness Test, an agility run, a lift and carry task ...

Performance Changes In A Division Iii Female Field Hockey Program Over A Competitive Season, Jacqueline Feliciano

Student Symposium

Athletics is a common source of muscle imbalances due to the repetitive movements performed in a sport. Muscle imbalances can create movement asymmetries between opposing muscles in the body that can cause overuse injuries or alter sport performance. In the sport of field hockey, athletes encounter repetitive movements on one side of their body due to the nature of the sport. The purpose of this study was to analyze the change in functional movement, balance performance, and power output throughout a competitive field hockey season. Eighteen field hockey athletes (mean age = 19.3 ± 1.2 years) were assessed in several ...

Comparison Of Single Leg Performance Tests In Athletes With And Without Acl Reconstruction, Cassandra Oberle

Student Symposium

Anterior cruciate ligament (ACL) injury rates among collegiate athletes continue to rise across 15 different men's and women's sports. Re-injury in ACL-reconstructed athletes occurs in 6-13% of reconstructed knees, and 2-6% sustain a ACL injury to the opposite leg. Strength and power have been found to be useful measures of muscle function. Clearance for sport participation following reconstruction and rehabilitation used to be based on a length of time rather than objective measurements of functional movements. Patients typically return to sport between 6 to 9 months postoperatively, which is now being questioned as to whether or not it ...

Thermoregulatory Adaptations Following Sprint Interval Training, Jonathan E. Wingo, Charlie P. Katica, Svetlana Nepocatych, Andrew T. Del Pozzi, Greg A. Ryan

Journal of Human Performance in Extreme Environments

Traditional endurance training typically involves weeks of long-duration (60–90 min) exercise performed at a moderate to vigorous intensity. An alternative paradigm, sprint interval training, is characterized by multiple bouts of short-duration, high-intensity exercise. Similar fitness benefits from the two paradigms have been demonstrated, but whether sprint interval training—like traditional endurance training—induces heat acclimation remains unclear.

Purpose

To test the hypothesis that sprint interval training performed over six sessions results in measureable thermoregulatory and cardiovascular adaptations consistent with heat acclimation.

Methods

Seven untrained men [mean ± SD, 13 ± 5% body fat, 22 ± 3 y, 3.1 ± 0.3 L ...

International Journal of Exercise Science

International Journal of Exercise Science 11(6): 754-763, 2018. Multiple investigations have confirmed carbohydrate mouth rinse (CMR) enhances high intensity endurance performance lasting under 1 hour, but the effects of CMR on high intensity intermittent exercise has received less attention. This study examined the effect of CMR on high intensity multiple sprint performances in a protocol designed to emulate a cyclocross or mountain biking event. Seven trained men (28.2 ± 6.8 years, 185 ± 9 cm, 85.3 ± 14.8 kg, VO₂peak 51.4 ± 7.3 ml/kg*min-1) completed two, 48 min high intensity intermittent cycling protocols ...

Attitudes Towards Sports Concussion In Australian Exercise Science Students. Does The Type And Level Of Participation In Sport Matter?, Billymo Rist, Janet A. Young, Alan J. Pearce

International Journal of Exercise Science

International Journal of Exercise Science 11(5): 739-753, 2018. Concussion in sport is a growing public health issue. However, research suggests that under-reporting of concussion by student-athlete cohorts reflects conflicting attitudes compared to the wider community. Interestingly, previous studies have focused on the attitudes and beliefs irrespective of the type or level of sport played at. This study explored concussion beliefs and attitudes in a cohort of Australian exercise science students, analyzing responses based upon the type and the level of sport participated. Two-hundred and ninety-four students (m = 208; f = 86; age 22 ± 5.2 years) responded to a series ...

A Preliminary Analysis Of The Relationship Between The Multistage Fitness Test And 300-M Run In Law Enforcement Officers: Implications For Fitness Assessment, Matthew R. Moreno, Robert G. Lockie, Charles L. Kornhauser, Ryan J. Holmes, J. Jay Dawes

International Journal of Exercise Science

International Journal of Exercise Science 11(4): 730-738, 2018. Law enforcement agencies (LEAs) often use fitness tests to assess recruits and incumbents. One fitness test that is gaining popularity is the 20-meter multistage fitness test (20m-MSFT). However, the potential length of this assessment, in addition to the repeated direction changes, means this test may not be appropriate for all officers (e.g. older officers, or those with physical impairments). The 300-m run is shorter, features no direction changes, and could provide an indication of fitness. The study purpose was to investigate the relationship between the 20m-MSFT and 300–m run ...

International Journal of Exercise Science

International Journal of Exercise Science 11(1): 717-729, 2018. Barefoot running is considered to decrease injury risk, but is not always practical, particularly while running on a fitness center treadmill. The purpose of this study was to compare the kinematics of shod, barefoot, and simulated barefoot running. Twelve subjects (age = 21.1 ± 1.2 years) who regularly run on a treadmill for fitness participated in the study. After a warm up, each runner ran on a Biodex RTM 400 treadmill set at 7.4 mph (approximately 3.3 m/s) in their own shoes, barefoot, and while running “like they ...

Stability Of Resistance Training Implement Alters Emg Activity During The Overhead Press, Jeremy R. Dicus, Michael E. Holmstrup, Kyle Shuler, Tyler Rice, Shawn Raybuck, Chelsea Siddons

International Journal of Exercise Science

International Journal of Exercise Science 11(1): 708-716, 2018. Kettlebells often replace dumbbells during common resistance training exercises such as the overhead press. When performing an overhead press, the center of mass of a dumbbell is in line with the glenohumeral joint. In comparison, the center of mass of the kettlebell is posterior to the glenohumeral joint. Posterior displacement of the kettlebell center of mass may result in less stability during the pressing motion. The purpose of this study was to examine muscle activity during an overhead press with resistance training implements of differing stability. Surface electromyography (EMG) for the ...

Field Test Performance Of Junior Competitive Surf Athletes Following A Core Strength Training Program, Tracy A. Axel, Jill Crussemeyer, Kevyn Dean, Douglas E. Young

International Journal of Exercise Science

International Journal of Exercise Science 11(6): 696-707, 2018. Lower body and core muscular strength are essential for optimal performance in many sports and competitive surfers have similar strength demands when maneuvering a surfboard to achieve competition success. Presently, the use of unstable surfaces is excessively utilized by surf coaches and trainers and to date, research does not support this as an effective training method for long-term improvements. Therefore, the purpose of this study was to determine the effectiveness of an 8-week Core Strength Training Program (CSTP) on a battery of field tests specific to assessing core musculature and lower ...

Exploring The Relationship Among Role Models, Physical Activity And Dietary Behaviors Among Young Adults Enrolled In A Weight Management Trial, Rachel Ingersoll, Meghan Mavredes, Melissa Napolitano

GW Research Days 2016 - Present

Background. Role models can have a profound impact on an individual’s development and lifelong behaviors. However, there are gaps in research when it comes to the impact of role models among young adults, particularly related to health behaviors. Previous research has primarily focused on youth, leaving a gap of knowledge surrounding the developmental life stage of young adulthood. Little research has been done examining health risk behaviors such as physical inactivity and unhealthy dietary practices. It is important for young adults to develop healthy habits in college, for many habits will follow young adults into their adult lifespan.

Purpose ...

Active And Passive Stress Management Mechanisms In Physically Active Young Adults, Krista Lepping, Melissa Napolitano

GW Research Days 2016 - Present

Background: Physical activity and stress are common factors that affect the health and wellness of young adults worldwide. Higher levels of stress in students can lead to increased blood pressure and decreased immune system defenses. Previous studies have found that students who report more physical activity also report lower levels of stress. Perceived stress is subjective, however, and therefore the amount of physical activity that affects stress levels could vary. Additionally, extensive research has yet to be conducted on the different coping mechanisms that physically active students use to relieve stress. These mechanisms may include physical activity as a stress ...

Childhood Cancer And Treatment Effects On Motor Performance, Jessica A. Peterson, Tom V. Darling

International Journal of Exercise Science

International Journal of Exercise Science 11(3): 657-668, 2018. Children with cancer report motor problems several years post treatment. Physical performance limitations can restrict the survivor's ability to participate fully in daily activities necessary for self-care, family life, and/or work. Motor performance in childhood cancer could be an important measure in symptom research. This review addresses motor performance limitations caused by cancer treatment in childhood cancer survivors. Several studies found performance deficits in strength and flexibility. Conflicting research in balance, coordination, and reaction time needs further consideration. The findings may indicate muscle atrophy as a cause of performance ...

Characteristics Of Helicopter Accidents Involving Male And Female Pilots, Scott S. Burgess, Robert O. Walton, P. Michael Politano

International Journal of Aviation, Aeronautics, and Aerospace

Studies examining aviation accidents have not found differences in accident rates by gender, though there may be gender differences in the types of accident. Baker, Lamb, Grabowski, and Rebok (2001) examined fixed-wing aviation accident rates of male and female private pilots and found that males were more likely to have accidents related to inattention or poor planning while female pilots were more likely to have accidents due to mishandling the aircraft. This research analyzed the National Transportation Safety Board’s aviation accident database system to examine the severity of injury and aircraft damage in rotary-wing (helicopter) accidents by gender. The ...

Anxiety And Alternative Facts: An Arts-Based Critical Social Improvisation Project, Rebecca Zarate, Nancy Beardall, Talaye Zarafshandardaky, Brooke Rutstein

Lesley University Community of Scholars Day

According to Grayson and Meilman (2011) the stakes are too high in current campus culture to not acknowledge the social roots of mental health issues such as anxiety, and concerns of students as related to campus safety. This arts-based, music performance project responded to concerns on campus from recent political and social events. More specifically, it aimed to explore the concept of “alternative facts” and how this idea plays with the collective concepts of truth and falsifications. It explored applications of clinical improvisation and the concept of collective anxiety as a social phenomenon expressed through arts including music, dance, and ...

A Two-Test Protocol For The Precise Determination Of The Maximal Lactate Steady State, Daniel Yaeger, Jena Winger, Kristin Murphy, Stasinos Stavrianeas

International Journal of Exercise Science

International Journal of Exercise Science 11(4): 681-695, 2018. The purpose of this study was to determine the efficacy of a two-test method for precisely identifying the Maximal Lactate Steady State (MLSS). Eight male competitive cyclists performed two bouts on a cycle ergometer. Following a maximal oxygen consumption (O_2max) test (66.91 ± 5.29 mL∙kg^-1∙min^-1) we identified the lactate deflection point using the visual deflection (T_Vis), Log-Log (T_Log), D_max (T_Dmax), RER = 1.00 (T_RER), ventilatory threshold (T_Vent), and the 1.0 mmol·L^-1 increase above baseline (T_{+1 ...}

PCSO-524™ (Lyprinol®/Omega-XL®), a supplement extracted from the New Zealand green-lipped mussel (Perna canaliculus), has been shown to moderate airway inflammation in asthmatic subjects. The purpose of this study was to determine whether supplementation with PCSO-524™ improves pulmonary and respiratory muscle function in non-asthmatic elite runners. Sixteen male, non-asthmatic elite runners were randomly assigned to either a treatment (PCSO-524™; 1 capsule contains 50 mg n-3 polyunsaturated fatty acids and 100 mg olive oil, n ...

Kinematics Of Swimming Of The Manta Ray: Three-Dimensional Analysis Of Open Water Maneuverability, Frank E. Fish, Allison Kolpas, Andrew Crossett, Michael A. Dudas, Keith W. Moored, Hilary Bart-Smith

Biology Faculty Publications

For aquatic animals, turning maneuvers represent a locomotor activity that may not be confined to a single coordinate plane, making analysis difficult particularly in the field. To measure turning performance in a three-dimensional space for the manta ray (Mobula birostris), a large open-water swimmer, scaled stereo video recordings were collected. Movements of the cephalic lobes, eye and tail base were tracked to obtain three-dimensional coordinates. A mathematical analysis was performed on the coordinate data to calculate the turning rate and curvature (1/turning radius) as a function of time by numerically estimating the derivative of manta trajectories through three-dimensional space ...
