Tales From Grades 1 Through 12:Understanding the Complex Web of Multiple Life Forces Located in Schools
From Grades 1 Through 12 Complex Web Multiple Life Forces Located Schools
2015/6/25
This study is a qualitative autoethnographical narrative of my grades 1 through 12 experiences in a Catholic school system in Alberta. Autoethnographical research interprets a culture by producing hig...
Ground Reaction Forces and Loading Rates Associated with Parkour and Traditional Drop Landing Techniques
Kinetics absorption forefoot roll
2015/5/14
Due to the relative infancy of Parkour there is currently a lack of empirical evidence on which to base specific technique instruction upon. The purpose of this study was to compare the ground reactio...
A Comparison of Ground Reaction Forces Determined by Portable Force-Plate and Pressure-Insole Systems in Alpine Skiing
kinetic analysis alpine skiing accuracy skiing mode pressure insole
2015/5/8
For the determination of ground reaction forces in alpine skiing, pressure insole (PI) systems and portable force plate (FP) systems are well known and widely used in previous studies. The purposes of...
Analysis of the vertical ground reaction forces and temporal factors in the landing phase of a countermovement jump
Impact absorption peak forces vertical jump
2015/5/5
In most common bilateral landings of vertical jumps, there are
two peak forces (F1 and F2) in the force-time curve.
Bilateral ground reaction forces and joint moments for lateral sidestepping and crossover stepping tasks
Badminton movement biomechanics injury
2015/4/21
Racquet sports have high levels of joint injuries suggesting the joint loads during play may be excessive. Sports such as badminton employ lateral sidestepping (SS) and crossover stepping (XS) movemen...
A COMPARISON OF UPPER-EXTREMITY REACTION FORCES BETWEEN THE YURCHENKO VAULT AND FLOOR EXERCISE
Gymnastics injuries biomechanics vaulting kinetics
2015/3/17
The purpose of this study was to examine reaction forces transmitted to the upper extremities of highlevel gymnasts during the round-off phase of the Yurchenko vault. A secondary purpose of this study...
Increasing Running Step Rate Reduces Patellofemoral Joint Forces
PATELLOFEMORAL PAIN CADENCE KNEE STRIDE LENGTH REHABILITATION
2017/5/19
Increasing step rate has been shown to elicit changes in joint kinematics and kinetics during running, and it has been suggested as a possible rehabilitation strategy for runners with patellofemoral p...
The Interaction of Trunk-Load and Trunk-Position Adaptations on Knee Anterior Shear and Hamstrings Muscle Forces During Landing
lower extremities anterior cruciate ligament injuries
2010/9/8
Because anterior cruciate ligament (ACL) injuries can occur during deceleration maneuvers, biomechanics research has been focused on the lower extremity kinetic chain. Trunk mass and changes in trunk ...
The effects of individually designed programs of physical training based on US army standards on motor abilities of Slovene armed forces personnel
Eotor readiness physical training plan
2009/12/25
Adequate physical readiness is a significant aspect of universal armed forces readiness and an integral part of military support. The aim of this research was to ascertain the effect of a training pro...
THE RELATIONSHIP BETWEEN 50m - FREESTYLE RESULTS AND CHARACTERISTICS OF TETHERED FORCES IN MALE SPRINT SWIMMERS：A NEW APPROACH TO TETHERED SWIMMING TEST
tethered swimming freestyle sprinters pulling force model
2009/8/26
This study tries to define the relationship between 50m freestyle competition
velocity in swimmers (criterion variable) on the one hand, and basic mechanical
characteristics of pulling force as Fmax...
Sagittal-Plane Trunk Position, Landing Forces, and Quadriceps Electromyographic Activity
anterior cruciate ligament ground reaction forces injury prevention risk factors
2010/9/9
Researchers have suggested that large landing forces, excessive quadriceps activity, and an erect posture during landing are risk factors for anterior cruciate ligament (ACL) injury. The influence of ...
Lower Extremity Kinematics and Ground Reaction Forces After Prophylactic Lace-Up Ankle Bracing
prophylactic braces external ankle supports landings injury prevention
2010/9/9
Long-term effects of ankle bracing on lower extremity kinematics and kinetics are unknown. Ankle motion restriction may negatively affect the body's ability to attenuate ground reaction forces (GRFs)....
