本文選題:成都 + 青年人; 參考:《成都體育學(xué)院》2017年碩士論文
【摘要】:目的:慢性病與現(xiàn)代生活方式中缺乏身體活動密切相關(guān),而我國不同年齡和職業(yè)階層的國民均存在明顯的“體力活動不足”現(xiàn)象,我國成年人經(jīng)常參加體育活動的人口比例僅為8.3%。積極開展運動健身,主要是通過增加身體能量消耗、改善各器官功能水平提高國民體質(zhì)和健康水平。目前,我國關(guān)于運動能量消耗的研究較少,尚沒有系統(tǒng)的中國人運動能量消耗的實測數(shù)據(jù),無法科學(xué)測量和計算運動時的能量消耗,直接影響運動健身活動的科學(xué)性和有效性。因此,針對我國國民能量消耗減少的現(xiàn)狀,科學(xué)分析中國人的運動能量消耗特征,建立中國人運動能量消耗標(biāo)準(zhǔn),科學(xué)指導(dǎo)健身活動,是中國實施“全民健身計劃”中最為重大和緊迫的科技基礎(chǔ)性工作。本研究選取特定人群,測定其在跑步運動中的能量消耗水平。為該人群跑步鍛煉提供科學(xué)的指導(dǎo),為同類研究提供理論依據(jù)。方法:通過張貼廣告、電話等方式招募到成都地區(qū)年齡為20~29歲、BMI18.5 kg/m2的志愿者(n=187)。通過“健康與身體活動狀況調(diào)查問卷”和血液學(xué)檢查排除不符合要求的志愿者(n=73),在符合要求志愿者(n=114)中選取60人作為研究對象。按照性別、BMI指數(shù)分為6個組,每組10人。使用Cortex MetaMax 3B氣體代謝分析儀測定靜息能量消耗和跑步運動(三個速度等級7km/h、8km/h、9km/h,每級速度運動6分鐘)能量消耗。其中靜息能量消耗取后五分鐘數(shù)據(jù),跑步運動能量消耗取各個速度的后兩分鐘的數(shù)據(jù)進行處理,根據(jù)攝氧量和二氧化碳呼出量來計算跑步運動能量消耗。用SPSS16.0統(tǒng)計軟件進行分析,以sx?表示結(jié)果,采用進行獨立樣本T檢驗、配對樣本T檢驗以及相關(guān)性分析進行比較分析,以P0.05表示差異具有顯著性,以P0.01表示差異具有非常顯著性。結(jié)果:(1)正常體重男性組靜息能量消耗非常顯著低于肥胖男性組(P0.01),正常體重男性組與超重男性組相比,沒有顯著性差異(P0.05),超重男性組非常顯著性低于肥胖男性組(P0.01);正常體重女性組靜息能量消耗非常顯著性低于肥胖女性組(P0.01),正常體重女性組與超重女性組相比,沒有顯著性(P0.05),超重女性組非常顯著性低于肥胖女性組(P0.01)。(2)青年男性與青年女性相比,靜息能量消耗無顯著性差異(P0.05);而青年男性的運動能量消耗、凈能量消耗均非常顯著性高于青年女性(P0.01)。(3)BMI正常組男性和女性的運動能量消耗均非常顯著性低于超重組和肥胖組(P0.01);超重組非常顯著性低于肥胖組(P0.01)。正常組的凈能量消耗非常顯著性低于超重組和肥胖組(P0.01);超重組非常顯著性低于肥胖組(P0.01)。(4)正常、超重、肥胖各組之間不同速度跑步運動能量消耗均無顯著性差異(P0.05)。(5)成都地區(qū)青年人靜息能量消耗與運動能量消耗之間呈顯著性正相關(guān)(P0.05)。結(jié)論:(1)成都地區(qū)青年人靜息能量消耗隨著BMI指數(shù)的增加而增加,正常體重至超重階段增長平緩,至肥胖階段增長顯著;青年男性的跑步運動能量消耗顯著性高于女性,凈能量消耗也顯著性高于女性。(2)成都地區(qū)青年人跑步運動能量消耗,隨著BMI指數(shù)的增長而增長;不同速度跑步運動能量消耗隨著速度增加出現(xiàn)增長趨勢但無顯著性差異;靜息能量消耗與運動能量消耗呈顯著性正相關(guān)。
[Abstract]:Objective: the chronic disease is closely related to the lack of physical activity in the modern lifestyle, and the people of different ages and professional classes in our country have obvious "insufficient physical activity". The proportion of people who often participate in sports activities in China is only 8.3%. actively carrying out exercise, mainly by increasing the energy consumption of the body and changing the physical activity. The functional level of good organs improves the national physique and health level. At present, there are few studies on energy consumption in China. There is no systematic survey data on the energy consumption of Chinese sports. It is impossible to measure and calculate the energy consumption of sports, which directly affects the scientificity and effectiveness of sports physical activity. Therefore, it is aimed at our country. The current situation of the reduction of national energy consumption, the scientific analysis of the characteristics of the energy consumption of the Chinese people, the establishment of the energy consumption standard of the Chinese people, and the scientific guidance of fitness activities are the most important and urgent scientific and technological basic work in the implementation of the national fitness program. The level of consumption. It provides scientific guidance for the running of the crowd and provides a theoretical basis for similar research. Methods: Volunteers (n=187), aged 20~29 years old and BMI18.5 kg/m2, were recruited through advertising, telephone and other ways. The "health and physical activity status questionnaire" and hematological examination were used to exclude the non conforming requirements. Volunteers (n=73), selected 60 people in compliance with the required volunteers (n=114), were selected as subjects. According to sex, the BMI index was divided into 6 groups, 10 people in each group. The energy consumption of resting energy and running exercise were measured by the Cortex MetaMax 3B gas metabolism analyzer (three speed grades 7km/h, 8km/h, 9km/h, and 6 minutes per level movement). The energy consumption was taken for five minutes, and the running energy consumption was processed by two minutes after the energy consumption. The energy consumption was calculated according to the oxygen uptake and carbon dioxide exhalation. The results were analyzed with the SPSS16.0 statistical software. The result was SX, and the independent sample T test was used, and the paired sample T test was used. The correlation analysis was compared and analyzed with P0.05 that the difference was significant, and the difference was very significant with P0.01. Results: (1) the resting energy consumption in the normal weight male group was significantly lower than that of the obese male group (P0.01). There was no significant difference between the normal weight male group and the overweight male group (P0.05), and the overweight male group was very significant. Significantly lower than the obese male group (P0.01), the normal weight female group resting energy consumption was significantly lower than the obese women group (P0.01), the normal weight female group compared with the overweight female group, there was no significant (P0.05), overweight female group was significantly lower than the obese women group (P0.01). (2) young men and young women, resting energy compared. There was no significant difference in consumption (P0.05), while the energy consumption and net energy consumption of young men were significantly higher than those of young women (P0.01). (3) the exercise energy consumption of men and women in the normal BMI group was significantly lower than that of the super recombinant and obese group (P0.01); the super recombination was significantly lower than that of the obese group (P0.01). The volume consumption was significantly lower than that of the super recombinant and obese group (P0.01); the super recombination was significantly lower than that of the obese group (P0.01). (4) there was no significant difference in the energy consumption of the running movement between the obese and the obese groups (P0.05). (5) there was a significant positive correlation between the resting energy consumption and the exercise energy consumption in the young people in Chengdu region (P0 .05) conclusion: (1) (1) the rest energy consumption of young people in Chengdu area increased with the increase of the BMI index, the normal weight to the overweight stage was slow and increased significantly to the obesity stage. The energy consumption of young men was significantly higher than that of women, and the net energy consumption was significantly higher than that of women. (2) the running energy of young people in the region of Chengdu. Consumption increases with the growth of the BMI index; the running energy consumption at different speeds increases with the increase of speed, but there is no significant difference; resting energy consumption is positively correlated with sports energy consumption.
