Exercise has traditionally been viewed as a contraindication for individuals with asthma, as it was believed to trigger or worsen acute asthma attacks. However, with scientific and appropriate exercise training, it has been proven that respiratory function and exercise capacity can be effectively improved and enhanced in asthma patients. This study aimed to compare the effects of different types of exercise on pulmonary function in adult patients with asthma using Network Meta-analysis. We conducted a comprehensive search of electronic databases such as PubMed, Cochrane Library, Web of Science, CNKI for randomized controlled trials (RCTs) that investigated the effects of exercise on lung function in adult patients with asthma from inception to February 2023. Information including on first author, publication time, total sample size, intervention period, interventions, and outcome indicators were collected, and relevant statistical analyses were performed using Stata 17.0 software and Revman 5.4. A total of 28 randomized controlled trials with 2,155 patients with asthma were finally included. The results of Network Meta-analysis showed that compared with control group, breathing training (BT)、aerobic training (AT)、relaxation training (RT)、yoga training (YG) and breathing combined with aerobic training (BT + AT) improved Forced Expiratory Volume in the first second (FEV1) levels; AT、BT、YG and BT + AT improved the level of Forced Vital Capacity (FVC); BT、AT、RT、YG and BT + AT improved Peak Expiratory Flow (PEF); BT、AT、and YG improved Forced Expiratory Volume in the first second/Forced Vital Capacity (FEV1/FVC).The results of SUCRA probability ranking showed that RT had the most significant effect on improving the FEV1[SMD = 1.13,95%CI(0.83,1.43), p<0.001] levels, BT + AT had the most significant effect on improving the FVC[SMD = 0.71,95%CI(0.47,0.95), p<0.001] level; YG had the most significant effect on improving the PEF[SMD = 0.79,95%CI(0.55,1.02), p<0.001] level. BT + AT and YG may be more advantageous in improving lung function in adult asthmatics.

Background: Preschool children are in a period of rapid physical and psychological development, and improving their level of physical fitness is important for their health. To better develop the physical fitness of preschool children, it is very important to understand the behavioral attributes that promote the physical fitness of preschool children. This study aimed to determine the effectiveness of and the differences between different physical exercise programs in improving preschool children’s physical fitness. Methods: A total of 309 preschool children aged 4–5 years were recruited from 5 kindergartens to participate in the experiment. They were cluster-randomly allocated into five groups: basic movements (BM) group, rhythm activities (RA) group, ball games (BG) group, multiple activities (MA) group, and control (CG) group. The intervention groups received designed physical exercise programs with a duration of 30 min 3 times per week for 16 weeks. The CG group received unorganized physical activity (PA) with no interventions. The physical fitness of preschool children was measured using the PREFIT battery before and after the interventions. One-way analysis of variance, a nonparametric test; generalized linear models (GLM); and generalized linear mixed models (GLMM) were used to examine differences during the pre-experimental stage among groups and to assess the differential effects of the intervention conditions on all outcome indicators. The intervention condition models were adjusted for potential confounders (baseline test results, age, gender, height, weight, and body mass index) explaining the main outcome variance. Results: The final sample consisted of 253 participants (girls 46.3%) with an average age of 4.55 ± 0.28 years: the BG group (n = 55), the RA group (n = 52), the BM group (n = 45), the MA group (n = 44), and the CG group (n = 57). The results of the generalized linear mixed model and generalized linear model analyses indicated significant differences for all physical fitness tests between groups, except for the 20 m shuttle run test and the sit-and-reach test after the interventions. Grip strength was significantly higher in the BG and MA groups than in the BM group. The scores for standing long jump were significantly higher in the MA group than in the other groups. The scores for the 10 m shuttle run test were significantly lower in the BG and MA groups than in the CG, BM, and RA groups. The scores for skip jump were significantly lower in the BG and MA groups than in the RA group. The scores for balance beam were significantly lower in the BG and MA groups than in the RA group and significantly lower in the BG group than in the BM group. The scores for standing on one foot were significantly higher in the BG and MA groups than in the CG and RA groups and significantly higher in the BM group than in the CG group. Conclusions: Physical exercise programs designed for preschool physical education have positive effects on the physical fitness of preschool children. Compared with the exercise programs with a single project and action form, the comprehensive exercise programs with multiple action forms can better improve the physical fitness of preschool children.

This study to evaluate the effects of different training modalities on blood lipids in type II diabetic patients by Network Meta-analysis, and provide a relevant basis for patients to develop exercise prescriptions to regulate blood lipids. Randomized controlled trials (RCTs) were retrieved from Zhiwang, Wanfang, Wipu, PubMed, EBSCO, Cochrane Library, and Web of Science that were published from the establishment to February 2023. Relevant statistical analyses were performed using Stata 17.0 software and Revman 5.4. A total of 35 randomized controlled trials with 2771 patients with type II diabetes were finally included. The results of Network Meta-analysis showed that, compared with the control group, Chinese traditional fitness exercise (CTF), resistance training (RT), and aerobic training (AT) could reduce total cholesterol (TC) levels; CTF, RT, whole body vibration training (WBV), and AT could reduce triacylglycerol (TG) levels; CTF, WBV and AT could increase High-density lipoprotein cholesterol (HDL) levels; CTF, RT and AT could reduce Low-density lipoprotein cholesterol (LDL) levels. SUCRA probability ranking results showed that CTF was the most effective in reducing TC[SMD= -0.57, 95% CI (-0.83, -0.31), p < 0.001], TG[SMD= -0.24, 95% CI (-0.36, -0.12), p < 0.001], LDL[SMD= -0.52, 95% CI (-0.70, -0.35), p < 0.001]; RT was the most effective in increasing HDL[SMD = 0.14, 95% CI (0.03, 0.26), p < 0.05]. CTF is more effective in improving TC, TG and LDL levels, while RT is most effective in improving HDL levels.
