Adequate aerobic exercise is viewed as an adjunct to the prevention and treatment of cardiovascular and cerebrovascular diseases, diabetes, and osteoporosis in the elderly , but there are no reports of the effects of various exercise regimens on blood microcirculation. The purpose of this study is to compare three types of aerobic exercise performed by older women: taijiquan, brisk walking and square dance, and to analyze the effects of the same training cycle (16 weeks), training frequency (5 times / week). and exercise time (90 minutes) in the microcirculation of the knee joint to provide a basis for research on improving the microcirculation of the elderly blood and preventing diabetes, hypertension, coronary artery disease and osteoporosis.
Because of the different frequency or time chosen during the 16-week training cycle, Taijiquan training has different effects on the blood microcirculation of the elderly. At present there are few studies of the effects of Taijiquan exercises on the microcirculation of human blood, and there are many cases. Zhang Yang (2017) selected 90 middle-aged and older women with a dominant right foot (30 in the Taijiquan group, 30 in the square dance group and 30 in the control group) for the exercise intervention . Of the knee joint showed that both taijiquan and square dance could improve the static balance function of middle-aged and elderly women, and the effect of taijiquan was better than that of the square dance group, which also the results of this study (taijiquan group, taijiquan - Group, after heating, the difference and rate of increase reached significant levels in both MBP and AVBC), and taijiquan had an effect on the reactivity of the blood of the knee joint. Crocirculation: Many Taijiquan movements require the practitioner to assume a half-height position and constantly monitor the stability of their own equilibrium, which plays an exercise role in the muscle groups of the trunk, hip and knee joint . Long-term exercise alters the changes in the stress levels of the muscle groups near the thigh and knee joints and then affects the microcirculation of the blood. WooJ et al. Taijiquan intervened in people aged 65 and 74 (90 men and 90 women) . The results showed that taijiquan exercise three times a week (60 min) increased BMD and blood perfusion in older women, but not significantly, while there was almost no analysis that abnormal synthesis of NO and disruption of metabolic factors with age in vascular endothelial cells decrease the microvasodilation capacity, resulting in decreased microvascular reactivity and decreased bone mineralization. Density and calcium loss, while taiichi exercises can increase blood microcirculation, promote calcium supplementation, and reduce calcium loss .
Currently there is a positive attitude towards the effect of square dancing on blood microcirculation: a middle-aged woman and an older woman with an average age of 59.3 years received 3-month square dance exercise intervention and before and after the experiments Changes in cardiovascular function were analyzed . The results showed that HR (P and <0.01), SPTI (P and <0.01), ED (P and <0.01), PAS (P and <0.01), PAD (P and < 0.01), PP (P and <0.01) and CAP (P and <0.01) decreased, DPTI (P and <0.01) and SEVR (P and <0.01) increased. The study showed that the difference between MBP and AVBC warming in middle-aged and older women changed significantly before and after the experiment, and the reactivity of the blood microcirculation changed, but not significantly. This study considers that the reason for the differences between the results of previous studies and the results of previous studies is that the content, intensity and time of square dance exercises between different subjects are difficult to reconcile, so that their effects on the microcirculation of the blood are not the square dance selected in this study requires subjects to kick, heel, step and rotate, and other movements. However, when monitoring the heart rate, it was found that square dancing is a low level of physical activity, the effect of the intervention on the reaction of microcirculation in the blood is not significant, it can take a long time to accumulate more effective.
In this study, the brisk walking group received 16 weeks of intervention, although MBP blood perfusion volume and AVBC blood cell velocity improved, but not significantly. The difference in results may be related to the lack of additional muscle strength training or the advanced age of the selected subjects.
Lanting Sean M confirmed our analysis and believed that the effect of exercise on blood microcirculation decreased with age . However, this study suggests that brisk walking has a positive impact on blood microcirculation in older women. analyzed serum calcium, phosphorus, and alkaline phosphatase levels in the elderly after 10 weeks of brisk walking intervention and found that alkaline phosphatase levels increased significantly, suggesting that brisk walking may promote the synthesis of human bone metabolism . When analyzing the movement characteristics of fast walking, this study finds that the extension of the pedal and the swing of the lower extremities are greater in the elderly than with normal walking, resulting in a higher exercise load on the lower extremities. Long, brisk walking results in more stress changes in the lower extremities, which in turn affects the microcirculation of the blood. The reason it hasn't reached a significant level may be because middle-aged and older women walk every day, so the effect is less.
Currently, there are few reports of the effects of taijiquan, brisk walking, and square dancing on the blood microcirculation in middle-aged and elderly women. Lu Tao practiced taijiquan, walked, and danced for 48 weeks (6 times a week, 40 minutes each time). ) in 105 older women aged 55 to 65 years and tested all subjects after 16, 32 and 48 weeks for changes in blood velocity . The results showed that taijiquan had the most obvious effect on improving blood speed. with increasing intervention time. In this study, the microcirculation of the knee joint blood was tested. After 16 weeks of training in the intervention group, the rate of increase in MBP in the Taijiquan group was significantly higher than that of the square dance group, brisk walking group, and control group, and the rate of increase in MBP in the square dance group was significantly higher than in the control group (P <0.05).The rate of increase of AVBC in the Taijiquan group was significantly higher than that of the brisk walking group and the control group. This indirectly confirms the point of view of Machado MV (Machado MV's) . Based on the analysis of the circumstances, we believe that the subjects in the Taiji group also have a lot of walking (a lot of walking time) in their daily activities, and older women are not as good as Taijiquan. Supports the opinion of this study: Taiji and brisk walking in older women for 48 weeks (5 times a week) found that Taijiquan was better at improving blood microcirculation in older women than brisk walking while dancing in a square, which required a longer intervention time required to increase the microcirculation in the blood due to the decreased physical activity, so the effect of improving the MAP in the short term was not good .
This study asserts that brisk walking and square dancing have different effects on blood microcirculation because it is difficult to standardize exercise intensity, such as different heart rate controls, step or cadence, different square dance modes and Difficulty exercising. Taijiquan (simplification of 24 styles) has a fixed exercise rhythm (accompanied by musical instructions), which allows the intensity of the exercise to be easily quantified. Regular and prolonged Taijiquan exercises are believed to be a reliable method for improving blood microcirculation in older women. It is worth noting that, although there were no significant changes in other indices of blood microcirculation in the Taiji group, the fast walking group, and the square group, there was no downward trend (compared to the control group). Age-related decrease in blood microcirculation. However, the study has limitations, such as the inability to compare the effects of the same training cycle, frequency, or time on outcomes, and the lack of comparisons of different age groups and genders, which will be the direction of follow-up research. .
