ABSTRACT
Objective:To investigate the effect of low-resistance elastic band resistance training on elderly patients with pre-frailty.Methods:This was a prospective research. A total of 119 elderly patients with pre-frailty admitted to the Geriatric Hospital of Medical Health Group of First People′s Hospital of Xiangshan County from August 2020 to May 2021 were selected as the research objects by simple sampling method, and divided into the control group of 60 cases and the intervention group of 59 cases according to the time of admission, and the control group received routine nursing methods, the intervention group used low-resistance elastic bands for resistance training intervention on the basis of the control group. The intervention time was 12 weeks. Frail Asthenia Screening Scale, Motor Function Evaluation Scale for the Elderly and Pittsburgh Sleep Quality Index Scale were used to evaluate the asthenia, motor function and sleep quality of the two groups before and after the intervention, and statistical comparison was made.Results:There was no significant difference in the asthenia, motor function and sleep quality between the two groups before the intervention ( P>0.05). The asthenia score after the intervention in the intervention group was (0.83 ± 0.38) points, which was lower than that in the control group (1.05 ± 0.43) points, and the difference was statistically significant ( t=2.93, P<0.01). The total score of motor function, social activity, mobility difficulty, daily care and physical pain after the intervention in the intervention group were (49.36 ± 4.68), (21.85 ± 3.71), (10.31 ± 1.65), (9.93 ± 1.80), (7.27 ± 1.65) points, respectively, which were lower than those in the control group (53.67 ± 5.20), (23.45 ± 3.62), (11.10 ± 1.81), (11.00 ± 1.88), (8.12 ± 1.65) points, the differences were statistically significant ( t values were 2.38 - 4.75, all P<0.05). The total score of sleep quality and the scores of sleep quality, sleep latency, sleep time, sleep efficiency, sleep disorder, hypnotic drug use and daytime functional disorder after the intervention in the intervention group were (6.54 ± 1.79), (1.02 ± 0.75) (0.95 ± 0.63), (0.95 ± 0.65), (0.80 ± 0.41), (1.29 ± 0.62), (0.53 ± 0.50), (1.02 ± 0.75) points, respectively, which were lower than those in the control group (8.92 ± 1.44), (1.38 ± 0.74), (1.40 ± 0.56), (1.37 ± 0.55), (0.93 ± 0.31), (1.58 ± 0.53), (0.72 ± 0.45), (1.53 ± 0.79) points, the differences were statistically significant ( t values were 2.06 - 7.97, all P<0.05). Conclusions:The implementation of low-resistance elastic band resistance training in elderly patients with pre-frailty can reduce the patient′s frail status, improve motor function and sleep quality, and has a certain clinical value.
ABSTRACT
Objective To investigate the effects of aerobic exercise on cardiorespiratory function in patients with obstructive sleep apnea/hypopnea syndrome (OSAHS).Methods A total of 84 patients with OSAHS were randomly divided into a control group and an aerobic exercise group (42 in each group).The control group was given only training in the activities of daily living (ADL).The acrobic exercise group was given ADL training combined with aerobic exercise training.The regime was maintained for 16 weeks.Each patient's VO2max,maximum heart rate (HRmax),exercise time to exhaustion,6-minute walking distance and quality of life (QOL) were evaluated before and after treatment.Results VO2max,HRmax,VO2max/HRmax,maximum exercise time,6-min walking distance and QOL all increased significantly more in the aerobic exercise group compared with the control group.Conclusion Aerobic exercise training can significantly improve cardiorespiratory function in patients with OSAHS.
ABSTRACT
Objective To observe the influence of exercise intensity on cardiorespiratory function in the elderly with coronary heart disease using simplified 24-action Taijiquan and jogging. Methods A total of 115 sedentary elderly patients with heart disease were randomly divided into a control group ( no exercise), a low-intensity exercise group, a medium-intensity exercise group (whose exercise was simplified 24-action Taijiquan at 40-60% of their individual maximum oxygen consumption (VO2max) for 90 to 200 minutes per week) and a high-intensity exercise group ( whose exercise was jogging on a treadmill at ＞ 70% of their maximum oxygen consumption for 200 minutes per week). The regime was maintained for 6 months. All patients accepted a treadmill exercise test before and after the 6 months of exercise to evaluate the changes in VO2max, maximum heart rate ( HRmax), VO2max/HRmax and exercise time (t). Results ( 1 ) After 6 months of exercise, VO2max, HRmax, VO2/HRmax and t had increased sisnificantly in all three exercise groups. Work capacity had increased 18.6% , 33% and 34.4% and HRmax had increased 9.3% , 13.8%, 19.1%. There was no difference between before and after in the control group. (2) Compared with the control group the average VO2max, HRmax and t of all three exercise groups had increased significantly. VO2 max was 9.4% , 26% and 23. 1% better; HRmax was 6.7% , 8.8% and 12% better; t was 3.5,4 and 4.9 minutes longer. (3) Compared with the low-intensity exercise group, VO2max, HRmax and t in the medium- and high-intensity groups increased significantly more. VO2max increased 16.6% and 13.7% more; HRmax increased 2.1% and 3.2% more and average t was 0.5 and 1.4 minutes longer. (4) There was no significant difference between the medium- and high-intensity exercise groups in terms of VO2max. (5) The incidence of self-reported adverse responses to exercise such as dizziness, chest stuffiness and fatigue in the high-intensity exercise group increased significantly compared with the other 3 groups. Conclusions Exercise can gradually improve cardiorespiratory function in the sedentary elderly with heart disease. The effects of medium-intensity exercise are similar to those of high-intensity exercise, but medium intensity is safer.
ABSTRACT
PURPOSE: The purpose of this study was to examine the effects of the cardiac rehabilitation program (Phase III) on cardiovascular and cardiorespiratory function in the elderly (age, > or = 60) who experienced acute myocardial infarction. METHODS: The design of research was nonequivalent control group pretest-posttest design. Subjects were 10 people in the experimental group and 10 in the control group. The intervention program was the cardiac rehabilitation program (Phase III), and was performed for 50 ~ 60 minutes, twice a week for 8 weeks. The dependent variables were the cardiovascular and cardiorespiratory function. RESULTS: Significant differences were shown in RHR, RSBP, SRPP, SBS, BMI, PT of the experimental group after the intervention. As for the differences in the amount of changes, there were differences among groups in RHR, RSBP, SRPP, SBS, PMET, and PT of the experimental group. CONCLUSION: The cardiac rehabilitation program (Phase III) may be effective in improving cardiovascular function and enhancing cardiorespiratory function in elderly patients with acute myocardial infarction.
