Joint torque utilization in throwing darts
نویسندگان
چکیده
In this study, we investigate the relationship between the skill level of subjects and their utilization of joint torque components, i.e., muscular torque, interaction torque and gravity torque. Results show that the subjects whose scores are high utilize the interaction torque of the elbow joint without shoulder displacement. Keywords— darts throwing, motion capturing, interaction torque

Utilization and compensation of interaction torques during ball-throwing movements.
The manner in which the CNS deals with interaction torques at each joint in ball throwing was investigated by instructing subjects to throw a ball at three different speeds, using two (elbow and wrist) or three joints (shoulder, elbow, and wrist). The results indicated that the role of the muscle torque at the most proximal joint was to accelerate the most proximal joint and to produce the effe...
متن کاملDesigning and Determining the Validity and Reliability of a Dart Throwing Observation Form: A 10th Grade Dart Module for Physical Education
Standard academic progress tests in physical education play an important role when it comes to assessing students’ progress, pinpointing their strengths and weaknesses and categorizing them. The present research has aimed to design and examine the reliability and validity of an observation form for the process of throwing darts. The testees participating in the research were darts players (male...
متن کاملCounteractive relationship between the interaction torque and muscle torque at the wrist is predestined in ball-throwing.
Many investigators have demonstrated that in swing motions such as ball-throwing, the motion of the proximal joint (shoulder) produced assistive interaction torque for the distal joint (elbow). In line with these studies, the shoulder and elbow motions would be expected to produce the assistive interaction torque for the wrist joint as well. However, we recently showed that the interaction torq...

Background and Objective: Choline is a precursor for the synthesis of the most important cholinergic neurotransmitter that induce the release of calcium from sarcoplasmic reticulum that finally leads to muscle contraction. The purpose of the current study was to survey the effect of one week choline supplementation on memory, reaction time, throwing darts and balance in recreationally active me...
متن کاملThrowing Darts: Random Sampling Helps Tree Search when the Number of Short Certificates is Moderate
One typically proves infeasibility in satisfiability/constraint satisfaction (or optimality in integer programming) by constructing a tree certificate. However, deciding how to branch in the search tree is hard, and impacts search time drastically. We explore the power of a simple paradigm, that of throwing random darts into the assignment space and then using information gathered by that dart ...
