Low-Force Muscle Activity Regulates Energy Expenditure after Spinal Cord Injury
DIABETES OBESITY ELECTRICAL STIMULATION EXERCISE METABOLISM
2018/4/24
Reduced physical activity is a primary risk factor for increased morbidity and mortality. People with spinal cord injury (SCI) have reduced activity for a lifetime, as they cannot volitionally activat...
Slower Walking Speed in Older Men Improves Triceps Surae Force Generation Ability
AGING ULTRASOUND FASCICLE TENDON GASTROCNEMIUS SOLEUS
2018/4/24
Purpose Older adults walk slower than young adults, but it is not known why. Previous research suggests that ankle plantarflexors may have a crucial role in the reduction of walking speed. The purpose...
Motion as manipulation:Implementation of motion and force analogies by event-file binding and action planning
Structure mapping Tool improvisation Rutherford-atom analogy
2015/7/21
Tool improvisation analogies are a special case of motion and force analogies that appear to be implemented pre-conceptually, in many species, by event-file binding and action planning. A detailed rec...
Correct, Fake and Absent Pre-Information Does Not Affect the Occurrence and Magnitude of the Bilateral Force Deficit
Bilateral force deficit strength training lower extremities unilateral strength
2015/5/22
The present study examined whether different pre-information conditions could lead to a volitional modulation of the occurrence and magnitude of the bilateral force deficit (BFD) during isometric leg ...
Relations Between Lower Body Isometric Muscle Force Characteristics and Start Performance in Elite Male Sprint Swimmers
Start performance maximum voluntary forces rate of force development
2015/5/19
The aim of the present study was twofold. The first aim was to examine the influence of absolute and relative lower body muscle force on kinematic component which determine the start performance. The ...
A Computational Fluid Dynamics Analysis of Hydrodynamic Force Acting on a Swimmer’S Hand in a Swimming Competition
Computational fluid dynamics swimming drag thrust thrust efficiency stroke analysis
2015/5/19
A stroke-analysis system based on a CFD (Computational Fluid Dynamics) simulation has been developed to evaluate the hydrodynamic forces acting on a swimmer’s hand. Using the present stroke-analysis s...
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...
Ground Reaction Force Differences Between Running Shoes, Racing Flats, and Distance Spikes in Runners
Footwear impact track
2015/5/4
Various shoes are worn by distance runners throughout a training season. This study measured the differences in ground reaction forces between running shoes, racing flats, and distance spikes in order...

Turning kick impact force Taekwondo Yongmudo
2015/4/30
The primary purpose of this research was to compare the impact characteristics of Taekwondo (TKD) and Yongmudo (YMD) player’s turning kick according to the target height. 5 highly skilled YMD and 5 TK...
The Effects of Height and Distance on the Force Production and Acceleration in Martial Arts Strikes
Sports acceleration Kung Fu law enforcement combat
2015/4/30
Almost all cultures have roots in some sort of self defence system and yet there is relatively little research in this area, outside of a sports related environment. This project investigated differen...
Number of Successive Cycles Necessary to Achieve Stability of Selected Ground Reaction Force Variables During Continuous Jumping
Reliability stability variability jumping ground reaction forces
2015/4/24
Because of inherent variability in all human cyclical movements, such as walking, running and jumping, data collected across a single cycle might be atypical and potentially unable to represent an ind...
