Assessment of Chorus activity on elderly health promotion

Objective: Assessment of chorus activity on elderly health promotion in the level of immunity, cardiopulmonary function and mental health. Methods: 3 groups of related data within 68 members in the chorus before training, training for 6 months and 12 months were counted and analyzed by computer analysis software. Compared with 50 cases of the same age group, that was collected at the same period, about data at 3 stages. Results: The average data of three phases of chorus is: immune level (CD4): 662.38, 761.22, 764.15, left ventricular ejection fraction (LVEF): 61.11, 61.13, 62.66, short axial shortening rate (FS): 32.61, 32.88, 33.65, lung function tidal volume (TV):1.06, 1.18, 1.16, forced vital capacity (FVC): 2.76, 2.85, 2.95, 1s forced expiratory volume (FEV1): 2.31, 2.42, 2.55, 1s rate (FEV1/FVC): 83.69, 84.91, 86.44, the chase volume (MVV is): 83.25, 81.11, 81.93, mental health score values 124.44, 125.67, 126.22, in addition to that, the TV, MVV and mental health score (SF - 36) did not change outside, other indicators, including the CD4, LVEF, FS, FVC, FEV and FEV1/FVC all have different degrees of ascension. Among them, the CD4 in training after 6 months improved obviously, little change after 12 months. Cardiac function index: EF and FS were improved after training 12 months. Lung function, FEV1, FVC, FEV1/FVC are ascending after training for 6 months and for 12 months. The average data of three phases)of the other group is: immune level (CD4) : 660.24, 661.85, 661.32, left ventricular ejection fraction (LVEF): 61.33, 61.28, 61.31, short axial shortening rate (FS): 32.55, 32.38, 32.46, lung function tidal volume (TV): 1.16, 1.17, 1.16，forced vital capacity (FVC): 2.74, 2.76, 2.76, 1s forced expiratory volume (FEV1): 2.30, 2.31, 2.30,1s rate (FEV1/FVC): 83.94, 83.69, 83.33, the chase volume (MVV is): 83.35, 82.49, 83.06, mental health score values 125.31, 124.86, 124.93. No changes were found in all measurement data of all 3 stages in the other group. Conclusions: The scientific, reasonable and continued chorus training has different degrees of help for raising the level of immune, improving cardiopulmonary function and raising the level of overall health to elderly.
