The Effects of Promotion Muscle Strength and Muscular Endurance by Horticultural Activities

By Chin-Yung Wung and 翁晴韻

Abstract

In recent years, the problem of population aging has become a global trend. The decline of muscle strength is not a kind of disease, but it is usually the potential reason that causes musculoskeletal system problem. In order to avoid the vicious cycle from the muscle weakness, it is very important for people to exercise and maintain the muscle strength when they are young. Many studies have pointed out that horticultural therapy has benefits on social, psychological, cognitive and hobby-developeded aspects. Relatively, few studies focus on the physiological aspect. Therefore, this study aims to conduct the analysis of muscle strength on common horticultural activities and explore the main muscles used when operating certain horticultural activities. Furthermore, this study investigates the differences in muscle strength, muscular endurance and grip strength between gardeners and non-gardeners, and the relations between the scales of muscle strength, muscular endurance and grip strength values and the types of horticultural activities. This study is a two-staged experiment. It uses the muscle strength analysis methods of electromyographic(EMG) to investigate the usage of every parts of body muscles in the first stage. Through the results of first stage, muslces that had higher amount of usage are taken as measurement subject in the second stage. The aim of the second stage is to compare the differences between gardeners an nongardeners in muscle strength, muscular endurance and grip strength. The measurement period is three months. The result shows that, when operating most of the horticultural activities, the extensor carpi radialis is mainly used for upper limb, upper fibers of trapezius is mainly used for body, and the mainly muscles used for lower limb are different depending upon participants, standing, squating or walking. Specifically, when standing, gastrocnemius and biceps femoris are mainly used; when walking, gastrocnemius is mainly used; when squatting, tibialis anterior is mainly used. In addition, the result of second stage indicates that the muscle strength of gardeners in upper fibers of trapezius, biceps brachii, biceps femoris and extensor carpi radialis were significantly higher than nongardeners. And the test for difference in the group of gardeners points out that horticultural activities can significantly improve the muscle strength of extensor carpi radialis, biceps brachii and upper fibers of trapezius and maintain the muscle strength of flexor carpi radialis and biceps femoris. But the muscle strength of quadriceps decreases significantly. The measurements result in grip strength indicats the grip strength of gardeners is significantly higher than non-gardeners, and the test for difference in the group of gardener shows that horticultural activities can significantly improve grip strength. However, there are no significant difference on muscular endurance between gardeners and non-gardenders. Integrating the research results of two stages in this study, operating horticultural activities can really improve or maintain grip strength and certain muscle strength and is a kind of leisure activities good for physical health. The study suggests that following researches could include psychological assessment tool to understand the benefit on physiopsychology, applying more detailed dismantling of horticultural motion in muscle strength analysis on rehabilitation in the future, and exploring the mainly used muscle on other types of horticultural activities more broadly, in order to provide more comprehensive applications on practice and research.近年人口老化已成為全球趨勢,肌力衰退雖非疾病,但往往是造成骨骼肌肉系統產生問題的前置病因。為了避免掉入肌力衰退所帶來之惡性循環,趁早鍛練及維持肌肉力量是非常重要的。諸多研究指出園藝治療具有社交、心理、認知及興趣嗜好等效益,但生理效益相關研究相對較少。因此本研究針對經常操作之幾種園藝活動進行肌力分析,以了解特定園藝活動主要使用之肌肉為何,再進一步探討園丁與非園丁間肌力、肌耐力及握力值之差異,以及探討園丁經操作幾項園藝活動後其肌力、肌耐力及握力值與園藝活動類型間之關係。 本研究分為兩階段實驗,第一階段利用肌電圖(EMG)之肌力分析方法,探討操作普遍園藝活動時身體各部位肌群使用情形,並由第一階段之研究結果依肌肉使用程度篩選出使用程度較高之肌群作為第二階段測量之標的。第二階段主要比較園丁(實驗組)及非園丁(對照組)肌力、肌耐力及握力之差異,測量期間為三個月。 研究結果顯示,大多數園藝活動於操作時身體上肢主要使用肌為伸腕肌,軀 幹主要使用肌為斜方肌,下肢主要使用肌會因其站、蹲或走動而在主要使用肌上較不一致,於站姿操作之園藝活動(小鏟子鏟土、整枝修剪)時則主要使用肌多為腓腸肌及股二頭肌,走動之園藝活動(提式澆水及綠籬修剪)時,下肢主要使用肌為腓腸肌;蹲姿的園藝活動(拔雜草、小鋤頭鏟土、小耙子耙土)時,下肢主要使用肌皆為脛前肌。而第二階段研究結果發現園丁組之斜方肌、肱二頭肌、股二頭肌及伸腕肌肌力顯著高於非園丁組,且於園丁組內差異檢定結果發現園藝活動能顯著提升伸腕肌、肱二頭肌及斜方肌肌力,維持屈腕肌、及股二頭肌之肌力,但在股四頭肌肌力表現上有顯著下降。握力測量結果發現,園丁組握力顯著高於非園丁組,且園丁組內差異檢定結果發現園藝活動能顯著提升握力。肌耐力表現上園丁組與非園丁組間無顯著差異。 綜合本研究兩階段之研究結果可得知,操作園藝活動確實能提升或維持握力 及某些特定肌群的肌力,是一項有利身體健康的休閒活動。建議後續研究能納入心理評估工具來同時了解生心理之效益、於肌力分析方面能更詳細將園藝活動之動作拆解以利於未來復健應用上,以及更廣泛地探討其他園藝活動類型之主要使用肌,以供未來更全面性的實務及研究應用。中文摘要…………………………………………………………………………….…..I 英文摘要………………………………………………………………………………..II 目錄………………………………………………………………………………….…IV 圖目錄…………………………………………………………………………………..V 表目錄……………………………………………………………………………….…VI 第一章 緒論…………………………………………………………………………...1 第一節 研究背景與動機…………………………………………………………...1 第二節 研究目的…………………………………………………………………...2 第三節 研究限制…………………………………………………………………...2 第四節 研究流程…………………………………………………………………...3 第二章 文獻回顧……………………………………………………………………...5 第一節 園藝治療相關研究………………………………………………………...5 第二節 肌力分析相關研究……………………………………………………….22 第三章 研究方法………………………………………………………………….....31 第一節 第一階段研究方法……………………………………………………….31 第二節 第二階段研究方法……………………………………………………….42 第四章 結果與討論………………………………………………………………….47 第一節 第一階段研究結果-園藝活動之肌力分析…………………………….47 第二節 第二階段研究結果-園丁與非園丁肌力、肌耐力及握力之表現…….69 第五章 結論與建議………………………………………………………………….80 第一節 綜合討論………………………………………………………………….80 第二節 結論……………………………………………………………………….88 第三節 研究應用………………………………………………………………….89 第四節 建議…………………………………………………………….................90 參考文獻……………………………………………………………………………….91 附錄一、園藝活記動紀錄單……….………………………………………………….99 附錄二、活動紀錄單…………………………………………………………………10
