Background: Lack of physical activity in individual has a big impact towards brain as if in the cognitive parts of the brain, especially decision making and memory. The relation between physical activity and cognitive ability is related to angiogenesis and neurogenesis that is more optimal in individuals who do their physical activity routine. Plyometrics and Aerobic exercise are proven to have a positive effect on the body, but there has been no further research on the comparison of the two sports. Aim: to understand the comparison between plyometrics exercise with aerobic exercise towards decision-making in young adults . Methods: This study used quasi experimental design pretest and posttest. The subjects were 39 aged, all of whom are students of Fakultas Kedokteran Universitas Diponegoro. Subjects divided into 3 groups as control, Plyometrics exercise, and Aerobic exercise. Decision-making score measured by IOWA Gambling Task (IGT). Data’s significance was analyzed with paired t-test. Results: There was significant difference in decision-making score before (pre-test) and after (post-test) Plyometrics and Aerobic exercise (p<0,05). Nevertheless, higher score was found in experimental group 1 which is the Plyometrics exercise (p=0,000). Furthermore, there was significant difference towards decision-making score in experimental and control group (p<0,05). Conclusion: Plyometrics and Aerobic exercise increase decision-making score for young adults. A more significant increase was found in the Plyometrics group (p=0,000).

Background: Sedentary lifestyle is widely adopted by the society. Sedentary lifestyle is associated with limited physical activity, thereby increasing the risk of diseases, as well as reducing fitness. Fitness is assessed with VO2Max. However, people with sedentary lifestyle are reluctant to exercise, thus the authors want to see whether briskwalking, an easy exercise and HIIT, a short-time exercise can increase VO2Max. Research Method: Quasi-experimental research with a pre-test and post-test comparison group design. 60 young adult women were divided into three groups, namely brisk walking, HIIT, and control by using purposive sampling. The brisk walking group did brisk walking and HIIT did HIIT aerobics for six weeks, three times in every week. The control group was not treated. All subjects performed VO2Max pretest and posttest with Cooper test. Result: The VO2Max value for brisk walking and HIIT increased by averages of 9.83±3.93 and 8.84±4.76, while the control decreased by -3.97±4.02 The result from paired t-test and Wilcoxon shows significancy thus indicating a significant difference of VO2 max value before and after the treatments towards the brisk walking, HIIT, and control groups. After the Mann Whitney test is performed, no significant difference is found between brisk walking and HIIT, whereas there is a significant difference between brisk walking and control, and also between HIIT and control. Conclusion: Brisk walking and HIIT can increase VO2Max. However, there was no difference in the increase between brisk walking and HIIT.Key Words: VO2Max, brisk walking, HIIT
