角度與單槓運動訓練對握力之影響

Abstract

在近年來台灣的肥胖人口持續增加，許多人藉著運動來保持身體的健康，因此，本實驗將研究運動對於握力是否會有所影響，然而在許多的運動項目當中，本組選擇吊單槓和槓上支撐這類較依賴手部運動的運動方法，因為在這兩種運動技巧上，身體的協調性和抓力是非常重要的，所以本實驗將利用握力器去測量進行單槓運動前、後，是否對握力有所影響。除了運動的因子以外，本實驗還加入角度因子，因在單槓運動後預測量握力時，每個受測者的測量姿勢皆不同，因此本實驗欲加入角度的因子來探討測量時之手臂角度是否對握力有實質上的影響。 在實驗過程當中，本實驗發現手在不同的狀況之下，會有「慣用手」施力大小的問題存在，在吊單槓後和槓上支撐後，抓力和運動前相比都有明顯降低的現象，以此次實驗來看，右手在運動完的抓力平均都會小於左手，但是經過了每周的持續運動，雖然在運動完抓力會降低，但是每周運動完的抓力有逐漸上升的現象。因此可以得知，在習慣進行某種運動之後，將可促進其運動的部位成長。 此次實驗可以改進的地方在於樣本數據可以更多，本實驗受測者只有六人，雖然資料數足夠滿足常態分配，但其獨立性太低，因此可以藉由增加受測者來提高樣本獨立性。除了以單槓運動及角度為變因之外，尚可增加不同的變因，如手掌還有其他能夠施力的不同部位，例如手指力，藉由不同的儀器去測量手指和抓力之間的相關性，這也是可另外進行探討的方向之一。

Taiwan’s population of obesity increases continuously. Many people keep their body’s health by exercising. Therefore, this experiment will research a study that whether doing exercise can affect grip or not. However, in many kinds of sports, our group chooses hanging horizontal bar and the support bar which depend on exercise by hands. Because of in these kinds of exercise skills, the physical coordination and grip are very important. So this experiment will use spring-grip dumb-bells to measure whether it will affect before exercise or after exercise. Except the factors of exercising, this experiment also adds angularity factor. Because after measuring the grip on experiment will add the angularity factor to discuss whether the angle will have the essential effect of grip. In the process of experiment, this experiment finds that under the different circumstance, it would have the problem of force due to dominant hand. After hang horizontal bar and the support bar, the grip decreases obviously before exercise. Therefore, in this experiment, the average of grip of right hand is smaller than left hand after exercising. By exercising continuous every week, although the grip decreases after exercising, but the grip increases gradually after exercise every week. Therefore, we can know that after doing exercise continuously, it can promote the growth of the part where exercise. The improvement of this experiment is the sample. The sample can be more. There are six participants in the experiment. Though the data reach the common distribution, the independence is too low. Therefore, we can increase the participants to improve the sample independence. Besides, except for horizontal bar exercise and angel for variable factors, we can add some different variable factors. Such as palms and other place which can force, for example, the pressure of fingers. By using different equipment to measure the relative between finger and grip is another direction to discuss.
