The Effect of High Intensity Interval Training (Hiit) on Short-Term Memory Among Medical Student of Diponegoro University

Abstract

Background: High Intensity Interval Training (HIIT) is an aerobic exercise consisting of high intensity of physical exercise interspersed with low intensity of physical exercise. HIIT has been known that can improve cognitive function. Medical students has low physical activity that can affect on cognitive function including short-term memory. Short-term memory is important in learning process which can affect on academic performance. Objective: To determine the effect of High Intensity Interval Training (HIIT) on an individual’s short-term memory. Methods: This study used quasi experimental pretest and posttest design. The research subjects were 29 female students of the Faculty of Medicine, Diponegoro University with the average age of 19-22 years with normal BMI, divided in 2 groups. Experimental group (n=14) was instructed to do 6 weeks of HIIT (3 times a week) and control group (n=15) was instructed to not to do any exercises. Short-term memory was measured with Scenery Picture Memory Test (SPMT). The significance of the data was analyzed with paired sample t-test and independent sample t-test. Results : A significant increase (p<0.001) in memory score before and after HIIT, from 18.07±1.49 to 20.21±1.37. The posttest memory score of HIIT group (20.21±1.37) was significantly (p=0.034) higher than the control group (18.67±2.23). Meanwhile, the memory score at the pretest between the 2 groups was no significant differences (p=0.621). Conclusion: HIIT can improves short-term memory.Keywords: High Intensity Interval Training (HIIT), Short-term Memory, Scenery Picture Memory Test (SPMT).

Cross-Sectional Analysis of the Effect of Physical Activity, Nutrition, and Lifestyle Factors on Medical Students’ Academic Achievement

“…Apart from the physical benefits of working out, physical activity increases cognition by stimulating an increase in blood flow to the brain. Cerebral blood flow is increased with an increase in cardiac output, which facilitates cerebral perfusion; therefore, higher-intensity workouts have been associated with increased short-term memory [ 2 ]. Aerobic exercise can enhance memory due to the increase in insulin-like growth factor-1 (IGF-1), which influences the rate of neurogenesis and formation of new neurons.…”

“…The benefits of having a diet rich in vegetables and fruits and low consumption of high-sugar beverages go beyond the decreased likelihood of developing conditions such as type II diabetes mellitus or hypertension. Physical activity increases cerebral blood flow and functional oxygen capacity and creates a statistically significant improvement in student memory [ 2 ]. Current literature also shows that most college-aged students adopt unhealthy lifestyle habits.…”

Parasitological and Hematological Study of Children Infected with Intestinal Parasites in Baquba City

“…Cyntia et al,2012 [27] stated that patients with parasite infections had lower rates of erythrocytes and hemoglobin levels, and there had been no appreciable increase in platelet levels. He also said that there had been no change in the volume of blood cells or the concentration of hemoglobin within the cell, Because of competition for the source of food and the absorption of food from the stomach lining, levels of hemoglobin and B12 decrease, as well as vitamins and lower blood levels, also the patient's health, immunity and social status…”
