背景资料：提供训练和放松益处的运动替代策略对于功能能力非常低的人来说是最佳的，他们也有并发症的高风险。太极拳是传统太极拳的修改形式，是一系列缓慢平衡的运动和呼吸，旨在提高能量水平并促进放松。目标：估计太极拳的能量消耗和心血管影响。测量的能量成本的具体活动，可以协助安全的运动处方的个人与非常低的能源reserves.Methods：一个方便的样本（n = 26）的健康成年人参加了这项研究，其中涉及完成调查，以估计功能能力和运动的参与，在一个选定的系列训练9台智C 'hih运动，和耗氧量测试，而运动进行。在坐姿和站立位以慢到快的节奏进行运动，包括下肢的前后和侧向运动、上肢的全肩运动范围以及深用力吸气和阶梯式呼气。人类活动概况被用来估计生活方式的能量消耗。结果：坐姿太极拳运动的代谢当量（MET）估计为1.5 +/- 0.17，慢速站立为2.3 +/- 0.34，快速站立为2.6 +/- 0.47。平均最大心率范围为预测最大心率的43%至49%。收缩压和舒张压较静息时平均升高8%。呼吸练习的平均MET范围为3至3.6。有没有差异的反应，性别或经验与太极exercise.Conclusion：用于执行太极C 'hih的运动需要的能量消耗相当于日常生活活动和低水平的运动，目前建议低运动耐量的人。因此，太极拳可能是许多慢性病人群健康促进的另一种方法。
Background: Alternative strategies for exercises that provide both training and relaxation benefits are optimal for persons with very low functional capacities who also are at high risk for complications. T'ai Chi C'hih, a modified form of traditional T'ai Chi, is a series of slow balanced movements and breathing promoted to increase energy levels and induce relaxationObjectives: To estimate the energy costs and cardiovascular effects of T'ai Chi C'hih. Measured energy costs of specific activities can assist with safe exercise prescription for individuals with very low energy reserves.Methods: A convenience sample (n = 26) of healthy adults participated in this study, which involved completion of surveys to estimate functional capacity and exercise participation, training in a select series of nine T'ai Chi C'hih movements, and oxygen consumption testing while movements are performed. Movements involving front to back and lateral moves of the lower extremity, full shoulder range of motion of upper extremity, and deep forced inhalation and stepped exhalations were performed at slow to fast cadences in sitting and standing positions. The Human Activity Profile was used to estimate lifestyle energy consumption. Exercise participation was quantified as Kcal/Kg(1) expended per week.Results: Metabolic equivalents (METs) for sitting T'ai Chi C'hih movements were estimated to be 1.5 +/- 0.17 and 2.3 +/- 0.34 for slow standing, and 2.6 +/- 0.47 for fast standing. Mean maximum heart rates ranged from 43% to 49% of predicted maximum heart rates. Mean increases in both systolic and diastolic blood pressures over resting were 8%. Mean METs of breathing exercises ranged from 3 to 3.6. There were no differences in responses to the movements by gender or experience with T'ai Chi exercise.Conclusion: The movements used to perform T'ai Chi C'hih require energy expenditure comparable with that for activities of daily living and for low level exercises currently recommended for persons with low exercise tolerance. Therefore, T'ai Chi C'hih may be an alternative approach to health promotion in many populations with chronic disease.
