Acl Factors: How Physical Condition, Mechanism, Sport, And Gender Affect Injury Probability, Bridger M. Rodoni 2015 Northern Arizona University

Acl Factors: How Physical Condition, Mechanism, Sport, And Gender Affect Injury Probability, Bridger M. Rodoni

Skyline - The Big Sky Undergraduate Journal

ACL injuries are one of the most feared and difficult injuries to return from in sports today. Occurring at a rate of 2.8 to 3.2 injuries per 10,000 athletes (Smith et al., 2012), the costs of ACL injuries go far beyond monetary. Athletes must endure an arduous recovery involving reconstructive surgery, multiple months of rehabilitation and the emotional tolls associated with each. As a result, efforts must be made to identify and counteract the factors that put athletes at an increased risk for an ACL injury. These factors include physical condition, mechanism, sport, and gender. By having ...


How Diet, Exercise, And Probiotics Influence Diversity In Gut Microbiota, Kristen Counsell 2015 Idaho State University

How Diet, Exercise, And Probiotics Influence Diversity In Gut Microbiota, Kristen Counsell

Skyline - The Big Sky Undergraduate Journal

Microorganisms are a fundamental part of life and essential to the mammalian digestive tract. Evolution has incorporated a vast number of intestinal alterations in morphology and physiology among the animal kingdom. When intestinal conditions change it alters the microbiota in the gut and digestive process. For certain chemical compounds to be broken down and absorbed, microbes with that ability must be present. Microbiota in the gut can also cause diseases such as irritable bowel syndrome (IBS) and colon cancer. One must maintain microbial diversity in the gut to stay healthy. To help improve and withhold diversity in the gut one ...

Mental Toughness And Coping Strategies In Collegiate Skiers, Julia Hayes 2015 Montana State University - Bozeman

Mental Toughness And Coping Strategies In Collegiate Skiers, Julia Hayes

Skyline - The Big Sky Undergraduate Journal

Pain is a mental construct that is seen as a warning signal to avoid injury. Athletes are able to overcome the mental roadblock of pain with many different coping strategies. Research has shown that pain coping mechanisms can help athletes to avoid the negative effect of pain on performance (Thelwell, Weston, Greenlees, 2005). Ignoring pain can be used to change pain perception. Pain tolerance has also been shown to increase with mental training during exercise, suggesting that specific coping mechanisms can have a strong impact on an athletes ability to maintain a high performance level during competition (Thelwell, 2005). The ...


The Acute Effects Of Ballistic And Non-Ballistic Concentric-Only Half-Squats On Squat Jump Performance, Timothy J. Suchomel 2015 East Tennessee State University

The Acute Effects Of Ballistic And Non-Ballistic Concentric-Only Half-Squats On Squat Jump Performance, Timothy J. Suchomel

Electronic Theses and Dissertations

The purposes of this dissertation were to examine bilateral asymmetry as a factor of postactivation potentiation, examine and compare the acute effects of ballistic and non-ballistic concentric-only half-squats on squat jump performance, and compare the potentiation and temporal profiles of strong and weak subjects following potentiation protocols that included ballistic and non-ballistic concentric-only half-squats. The following are major findings of the dissertation. Squat jump performance may be acutely enhanced following ballistic concentriconly half-squats; however the changes in performance do not appear to be related to bilateral symmetry. Ballistic concentric-only half-squats acutely improve various squat jump performance variables at various time ...

Relationship Between Concentric Velocity At Varying Intensity In The Back Squat Using Wireless Inertia Sensor, Kevin M. Carroll 2015 East Tennessee State University

Relationship Between Concentric Velocity At Varying Intensity In The Back Squat Using Wireless Inertia Sensor, Kevin M. Carroll

Electronic Theses and Dissertations

The purpose of this study was to determine the relationship between the Minimal Velocity Threshold (MVT) of 1RM and repetitions until failure testing conditions using the back squat exercise. Fourteen injury-free males with experience in the back squat volunteered to perform a 1RM and a submaximal (70% 1RM) repetitions until failure test, each during different testing sessions. Mean Concentric Velocity (MCV) was collected using a wireless inertia-measuring device. The last successful repetition in either condition was considered the MVT. A very small relationship between 1RM and repetitions until failure MVT was found (r=-0.135). There were no significant differences ...


Comparison Of External Kinetic And Kinematic Variables Between High Barbell Back Squats And Low Barbell Back Squats Across A Range Of Loads, Jacob Goodin 2015 East Tennessee State University

Comparison Of External Kinetic And Kinematic Variables Between High Barbell Back Squats And Low Barbell Back Squats Across A Range Of Loads, Jacob Goodin

Electronic Theses and Dissertations

This study compared peak force, peak power, peak velocity, impulse, work, and vertical displacement between the high bar back squat (HBBS) and low bar back squat (LBBS). Six trained males performed each using 20, 30, 40, 50, 60, 70, 80, and 90% of their recent training 1 repetition maximum. Dual force plates recorded force-time curve characteristics of ground reaction forces and four potentiometers tracked vertical and horizontal barbell displacement. Repeated–measures analysis of variance revealed a significant main effect for load (p<0.01) across all variables, but no significant effects for condition or interaction. The HBBS generated higher peak force in loads 20%–80%, higher peak power in loads 20%–60% and 80%–90%, higher peak velocity at every load, and greater vertical displacement at every load. The LBBS generated a larger impulse at loads 30%-90% and the HBBS generated more work at loads 20%, 40%, and 60%–90%.

The Physics Of Human Performance: An Ideal Lab, William B. Laing III, Harold Mayer 2015 Southern Adventist University

The Physics Of Human Performance: An Ideal Lab, William B. Laing Iii, Harold Mayer

Faculty Works

Physics lab goes to the gymnasium, where students calculate the mechanical power required to walk on an inclined treadmill in watts and convert to units power used to measure human performance: VO2, and METs. Students learn how to use two linear regression models: the ACSM "walking equation" to estimate the actual power expenditure of walking and the Rockport 1 mile test to estimate their own VO2max. Students use models to prescribe exercise parameters for themselves and for two cases. The IDEAL lab collaboration is developing labs that are open, applied to life, and rigorously quantitative.


Concussion Awareness And Educational Outreach Through A Website And Mobile Application, Daniel J. Brogan 2015 Ursinus College

Concussion Awareness And Educational Outreach Through A Website And Mobile Application, Daniel J. Brogan

Neuroscience Summer Fellows

In recent years concussions have become a more apparent problem in youth and adolescent sports. 1 in 5 high school students will sustain a concussion during the season. Due to medical and scientific advances, the diagnosis of concussions is becoming much simpler with key markers that are signs for an injury. Returning to play too soon before an athlete is fully recovered increases the likelihood that serious and irreversible neurological deficits can occur. Symptoms for concussions are necessary to track in order for an athlete to properly report their recovery to a physician. Doctors primarily rely on a patient’s ...
