【摘要】：研究目的:通过测量大学生不同(力量)负荷单一动作和组合动作抗阻训练的能量消耗,探讨抗阻训练能量消耗的特点及与相关因素之间的关系,建立不同(力量)负荷抗阻训练能耗方程,以便能科学合理的指导大学生运动健身,为抗阻训练在大学生群体健康促进中的应用和运动处方制定提供合理活动的推荐量和评价标准。研究方法:采用Cosmed K4b2便携式心肺测试仪间接测量抗阻训练能量消耗,对22名普通大学生抗阻训练过程中的能量消耗等相关指标进行测量,并根据体重、体成分等相关因素,对能量消耗特点及相关特点进行分析。研究结果:(1)中等(力量)负荷(12RM)与低(力量)负荷(25RM)单一动作两种抗阻训练中哑铃深蹲的能量消耗均最高,与其他单一动作抗阻训练比较差异具有统计学意义(P0. 01);抗阻训练过程中组间能量消耗存在较大差异,中等(力量)负荷组在第2组能量消耗达到最高(P0.01),低(力量)负荷组在第4组达到最高(P0.01);中等(力量)负荷(12RM)与低(力量)负荷(25RM)单一动作抗阻训练运动代谢当量分别在4. 01-6. 80 METs和3. 66-6. 98 METs之间。两种负荷下单一动作能耗和体重、BMI、去脂体重存在正相关(R=0. 686、0. 259、0. 865、0. 675、0. 373、0. 844,P0.01或P0.05),能耗与体脂百分比成负相关(R=-0. 283、-0.212, P0. 01),总体水平上,心率与能量消耗和相对摄氧量之间存在着线性相关(R=0. 630、0. 634, P0. 01)。(2)中等(力量)负荷(12RM)与低(力量)负荷(25RM)组合动作抗阻训练代谢当量分别在6. 53-7. 23 METs和5. 56-6. 24 METs之间,组合动作训练后,机体代谢水平在相当长的时间内仍处于较高代谢水平。两种负荷组合动作抗阻训练能耗和体重、BMI、去脂体重存在正相关的线性关系(R=0. 671、0.451、0.814、0.716、0.443、0.867, P0. 01),能耗与体脂百分比成负相关(R=-0. 234、-0.341,P0. 01),总体水平上,心率与能量消耗和相对摄氧量之间存在线性相关((R=0. 538、0.447、0.732、0. 437, P0. 01)。(3)运用相关及回归分析分别建立中等(力量)负荷(12RM)和低(力量)负荷(25RM)组合动作抗阻训练的能耗方程。中等(力量)负荷(12RM)组合动作抗阻训练的能耗方程:EEm (12RM) (Kcal/min)=0. 108Weight+0. 043HR-0. 018FFM-4. 802 (R2=0. 712)低(力量)负荷(25RM)组合动作抗阻训练的能耗方程:EEm (25RM) (Kcal/min)=0. 154FFM+0. 036HR-0. 056Weight-2. 74 (R2=0. 806)研究结论:1、低(力量)负荷(25RM)组合动作抗阻训练属于中等强度体力活动,中等(力量)负荷(12RM)组合动作抗阻训练属于大强度体力活动。抗阻训练对运动后静息能量消耗有一定影响。2、抗阻训练过程中,能量消耗受个体的体重、体脂百分比、去脂体重、BMI等因素的影响,尤以去脂体重的影响最高。3、线性回归方程的建立可以为大学生日常运动健身和抗阻训练提供科学依据。
[Abstract]:Objective: to investigate the characteristics of energy expenditure of resistance training and the relationship between energy consumption and related factors by measuring the energy expenditure of single and combined action resistance training for college students. The energy consumption equation of resistance training under different load can be established to guide college students' physical fitness scientifically and reasonably. To provide the recommended amount and evaluation standard of reasonable activities for the application of resistance training in the promotion of college students' group health and the formulation of exercise prescription. Methods: Cosmed K4b2 portable cardiopulmonary tester was used to measure the energy consumption of resistance training in 22 college students. The characteristics of energy consumption and related characteristics are analyzed. The results were as follows: (1) the energy consumption of dumbbell squatting was the highest in the single action resistance training of moderate (strength) load (12RM) and low (strength) load (25RM). The difference was statistically significant compared with other single movement resistance training (P0. There was significant difference in energy consumption between groups during resistance training. The energy consumption of the middle load group reached the highest in the second group (P0.01), and the low load group reached the highest in the fourth group (P0.01), and the energy consumption in the middle load group reached the highest in the second group (P0.01) and the low load group reached the highest level in the fourth group (P0.01). The metabolic equivalent of moderate (strength) load (12RM) and low (strength) load (25RM) single action resistance training was 4. 01-6. 80 METs and 3. 66-6. Between 98 METs. There was a positive correlation between the action energy consumption and the weight of the two loads and the weight of the BMI, degreasing (RV 0. 5%). 686,0. 259,0. 865,0. 675,0. 373,0. The energy consumption was negatively correlated with the percentage of body fat (P 0.01 or P 0.05). 283- 0.212, P0. At the overall level, there was a linear correlation between heart rate and energy consumption and relative oxygen uptake (RP0. 630,0. 634, P0. 01). (2) the metabolic equivalent of resistance training for moderate (strength) load (12RM) and low (strength) load (25RM) was 6. 5% respectively. 53-7. 23 METs and 5. 5. 56-6. Between 24 METs and 24 METs, the metabolic level of the body was still in a high level for a long time after combined movement training. There was a positive linear relationship between energy consumption and body weight in two kinds of load combined action resistance training and BMI, degreasing weight (RP0. 671,0.451,0.814,0.716,0.443,0.867, P0. 01), the energy consumption was negatively correlated with the percentage of body fat (RV-0. 234L -0.341g P0. At the overall level, there was a linear correlation between heart rate and energy consumption and relative oxygen uptake (R0. 0. 538,0.447,0.732,0. 437, P0. 01). (3) using correlation and regression analysis, the energy consumption equations of combined action resistance training with moderate (strength) load (12RM) and low (strength) load (25RM) were established respectively. Medium (strength) load (12RM) combined action resistance training energy consumption equation: EEm (12RM) (Kcal/min) = 0. 108Weight 0. 043HR-0. 018FFM-4. 802 (R2C0. 712) Energy consumption equation: EEm (25RM (Kcal/min) = 0 for low (strength) load (25RM) combined action resistance training. 154FFM 0. 036HR-0. 056 Weight-2. 74 (R2 / 0. 806) the conclusions are as follows: 1. Low (strength) load (25RM) combined action resistance training belongs to medium intensity physical activity, while moderate (12RM) combined action resistance training belongs to high intensity physical activity. Resistance training has a certain effect on resting energy expenditure after exercise. 2. During resistance training, energy consumption is affected by body weight, percentage of body fat, fat-free body weight, BMI and so on. The establishment of linear regression equation can provide scientific basis for daily exercise fitness and resistance training of college students.
