Abstract

Background: Concentration is an important component of cognitive function. However, many college students experience reduced attention spans, often lasting only 10 to 15 minutes. Previous studies have shown that poor concentration levels remain common among university students. Physical exercise, such as jogging, may improve brain function and enhance concentration. This study aimed to evaluate the influence of jogging duration on concentration levels among university student. Methods: This experimental study was conducted in 2024, involving medical students from a university in Jakarta, Indonesia. Participants were screened using the Physical Activity Readiness Questionnaire (PAR-Q) and selected through random sampling. Respondents were divided into three groups: a 10-minute jogging group, a 30-minute jogging group, and a control group without jogging intervention. The intervention was conducted for 8 weeks at each participant’s location. Concentration levels were assessed before and after the intervention using the Concentration Grid Test, administered at the university. Data were analyzed using ANOVA to compare changes in concentration scores and the Kruskal-Wallis to compare post-intervention scores among groups.Results: A total of 28 students participated, with females comprising the majority of participants (64.3%; n=18). The 10-minute jogging group demonstrated a significant improvement in concentration levels compared with the control group (p=0.004). Concentration Grid Test scores increased by 4.6 points in the 10-minute jogging group (p<0.001), and by 3.8 points in the 30-minute jogging group (p=0.003). Conclusions: A 10-minute jogging session improves concentration levels among university students, suggesting that short-duration physical activity provide cognitive benefits and may support academic performance and well-being.

Abstract

Degenerative processes in the central nervous system contribute to in cognitive function decline in the elderly. Physical exercise may prevent this decline. However, elderly people often require modified forms of activity to ensure both safety and effectiveness. This study aimed to investigate the the effect of chair-based exercise (CBE) on cognitive function in elderly people. This study was conducted a two nursing homes using a two-group pretest and posttest experimental design with a control group. All participants were informed about the procedures of study, provided written informed consent, and underwent an initial cognitive assessment using the mini-mental state examination (MMSE). Participants in the intervention group engaged in CBE sessions over a four-week period. Following the intervention, cognitive function was reassessed in both groups. The Wilcoxon signed-rank test was used to analyze within-group changes, while independent t-tests were used to assess between-group differences in cognitive function scores. A significant improvement in cognitive function was observed in the intervention group after the four-week CBE program (p = 0.008). Moreover, a significant between-group difference in cognitive score changes was found (p = 0.003), favoring the intervention group. In conclusion, a four-week CBE program significantly improved cognitive function among elderly participants. These findings support the use of CBE as an accessible and effective intervention to promote cognitive health in elderly people.
