RESUMEN
Purpose: To systematically evaluate the effect of Baduanjin on the balancing ability of older adults. Methods: The systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Six electronic databases were searched for eligible studies. Data synthesis and statistical analysis using a random effects model were performed with Review Manager 5.4. Random-effects weights were used to pool the effect sizes. Publication bias was assessed by funnel plot. Results: A total of 17 RCTs involving 1,267 patients were identified. The meta-analysis showed that the Baduanjin group was significantly superior to the control group in balancing performance measured by Berg balance scale [mean difference (MD) 4.82; 95% confidence interval (CI) 3.40 to 6.24, P < 0.00001], Timed Up and Go (MD -2.21, 95% CI -2.69 to -1.74, P < 0.00001) and Eye Closed One Leg Standing Balance (MD 2.01, 95% CI 0.79 to 3.23, P < 0.00001) tests. Conclusion: Baduanjin can effectively affect the balancing ability of older adults. More high-quality evidence-based studies are required to confirm these findings.

RESUMEN
Purpose: To evaluate the effect of a short-term HIIT program on the selected health-related parameters for overweight/obese young adult women in a university context. Methods: A total of 48 participants were randomly divided into two groups. The exercise group (HIIT) received a HIIT intervention of aerobics for 4 weeks, while the control group (CON) received no training. Body composition including waist circumference (WC), body fat percentage (BF %), Cardiorespiratory fitness (VO2max), the score of Self-Rating Depression Scale (SDS), and Stroop word-color test (SCWT) results were assessed before and after the intervention along with within- and between-group comparisons. Results: All the indices were significantly improved in HIIT group (p < 0.01) after 4 weeks of intervention. No significant changes were found in CON. There were significant differences between HIIT and CON in cardiovascular fitness (p < 0.01), SDS (p < 0.01) and SCWT (p < 0.05) before and after 4 weeks. In addition, weekly measurements of HIIT effects showed significant changes (p < 0.01) from the second week in the variables of body composition, VO2max, SDS and SCWT when compared with the baseline and maintained the tendency till the end of program. Conclusion: The short-term HIIT aerobics of the campus program conducted in a non-lab setting induced significant improvements in body composition, cardiovascular fitness, psychological well-being and executive function in overweight young female adults.
