The Effect Of Tactical Tasks And Gear On Muscle Activation Of Swat Officers, Jason M. Keeler
The Effect Of Tactical Tasks And Gear On Muscle Activation Of Swat Officers, Jason M. Keeler
Theses and Dissertations--Kinesiology and Health Promotion
Special Weapons and Tactics (SWAT) officers constitute a subgroup of specialized law enforcement officers that perform a variety of tactical operations while wearing approximately 40 kg of tactical gear. Lower back pain is a prevalent musculoskeletal injury suffered by SWAT officers. Tactical gear places significant stress on the lower back. Thus, it is important to quantify the effect that tactical gear has on muscle activation levels of torso musculature while performing occupational tasks. Electromyography was evaluated on 20 male subjects (age: 34.7±4.5 yr.; height: 1.79±.10 m; body mass: 91.53±17.32 kg; mass of gear: 13.82±1.90 kg) while performing four tactical tasks …
Factors Influencing Peripheral Skin Temperature Circadian Rhythm In Young Adult Males, Hannah Tranel
Factors Influencing Peripheral Skin Temperature Circadian Rhythm In Young Adult Males, Hannah Tranel
Theses and Dissertations--Kinesiology and Health Promotion
Periodic cues, including scheduled exercise, social interactions, sleep habits, and feeding time, have been shown to alter the circadian system. A disruption in circadian rhythms has been shown to have negative effects on health. Frequent skin temperature measures have been shown to be a valid method of assessing circadian rhythm parameters. The purpose of this study was to determine group mean differences in temperature amplitude, stability and lag measures among groups of young men of varying (optimal, fair and poor) adiposities. The strength of the association among the temperatures parameters and measures of body composition, physical fitness and activity, nutritional …
Is There A Relationship Between Hip Structure, Hip Muscle Strength, And Lower Extremity Frontal Plane Kinematics During Treadmill Running?, Michael William Robinson Baggaley
Is There A Relationship Between Hip Structure, Hip Muscle Strength, And Lower Extremity Frontal Plane Kinematics During Treadmill Running?, Michael William Robinson Baggaley
Theses and Dissertations--Kinesiology and Health Promotion
INTRODUCTION: Excessive hip adduction (HADD) has been associated with a number of lower extremity overuse injuries, and it has been suggested that it may be the result of reduced strength of the hip abduction musculature. Hip structure has been postulated to influence both hip abduction (HABD) strength and HADD. The purpose of this study was to investigate the relationship between hip structure, HABD strength, and frontal plane kinematics during running. METHODS: Peak isometric HABD strength, lower extremity kinematics, femoral neck-shaft angle (NSA), and pelvis width-femur length (pw-fl) ratio were recorded for 25 female subjects. Pearson correlations (P < .05) were performed between variables. RESULTS: A fair relationship was observed between femoral NSA and HABD strength (r = …
