Comparative study of effect of high intensity interval training and playing mobile games on reaction time in young adults, using Stroop test

Abstract: Background: Enhanced cognitive abilities are imperative across all facets of life, right from decision-making and hazard avoidance to athletic performance and procedural efficiency. The impact of mobile technology on cognition has been an area of profound scientific inquiry. Aims & Objectives: The present study aimed to examine and compare the effects of high-intensity interval training (HIIT) and playing endless running mobile games on cognitive functions in young adults. Material & Methods: A total of 60 young adults, aged 18-25 years, were divided into two groups. Group 1 practiced HIIT alone for 4 weeks, while Group 2 practiced HIIT and played the mobile game \"Temple Run\" during the same period. Cognitive performance was assessed using Stroop Colour and Word test, widely used test in cognitive psychology, which measures selective attention, processing speed, and interference resolution. Results: The results showed significant improvements in reaction time for both groups, indicating positive effects in the cognitive realm. However, no significant differences were observed in reaction time between the HIIT-only (group 1) and HIIT-plus-mobile game (group 2) groups. Conclusion: This novel study demonstrates that high-intensity interval training (HIIT) by itself is an effective method for augmenting cognitive performance indices, like reaction time and processing speed, in young adult population of age 18-25 years, with mobile games providing no additional benefits.   Limitations: Further study is indicated in a larger cohort to explore the long-term impact of HIIT on broader range of cognitive abilities.
