Construction of an Inexpensive Response Timer

Abstract

The previous paper by Professors Hutton and Doolittle uses a rather controversial methodology for evaluating electromyography signals. Of course one of the purposes of “Research Notes” is to publish approaches that are non-traditional. However, I felt it was important to identify questions that might be raised about Hutton and Doolittle's methodology. Thus, I requested the following short response by Professor Yates and then a response by Hutton and Doolittle. I invite additional responses to either Hutton or Doolittle and Yates.

A Multidimensional Timing Device for Cinematography

Abstract

Six tests were developed for the purpose of measuring selected basic skills in ice hockey. The test-retest method indicated four tests as reliable. Validity coefficients for each of the four tests when compared to subjective ranking in each skill ranged from .75 to .96. Intercorrelations were computed among the tests. The puck carry test correlated with the other three tests and was determined the best single-item for measuring overall ability. It was concluded that an ice hockey test battery should include at least three of the tests.

Device for on-the-water measurement of rowing output

All those who compete in the sport of rowing have used the land rowing machine, Ergometer (commonly called the ‘erg’), manufactured by Concept II (Morrisville, Vermont, USA). Ergon is the Greek word for work, hence the Ergometer measures work. Rowers are commonly ranked according to their ‘erg score.’ The fault in this ranking is that the land Ergometer cannot account for many of the important technical aspects associated with rowing on the water. The goals of this project were to (1) develop a system for on-the-water measurement of work during rowing and then (2) demonstrate the potential of such a system to quantify performance and improve rowing technique. To achieve these goals, force was measured using strain gauges glued to the shaft of the rowing oar and angular displacement was measured using a potentiometer. The force and displacement measurements were sent to a microcontroller, which calculated the total work done in a particular stroke, as well as other parameters, and displayed the values to the rower. The parameters were used to evaluate the performance of three collegiate rowers on the water. The data were also used to plot force profiles, which were reviewed with each rower and the coach to illustrate the rowers’ habits and facilitate improving technique. One rower was ‘tutored’ with the device through five on-the-water practices, after which his force profiles and parameter values demonstrated significant improvement. The device not only provided a standard to which all rowers were compared on the water, but also supplied the rowers with important information on technical aspects of their strokes and pacing themselves.     

我国竞技速度滑冰竞争力评价指标体系构建与认证
