Effect of Prolong Sitting for Continuous Three Hours on Neuromuscular and Cardio-respiratory System in College Students: An Observational Study

Abstract

Background: Prolonged sitting has adverse effects on the body’s physical fitness. Since the students sit in college during lecture hours, their physical fitness is compromised. Some studies have proved that inactivity can affect various systems. Method: The study included 50 students randomly whose ages ranged between 18-22 years of college going. The students were then assessed for flexibility with the Sit and Reach test, aerobic capacity with the Harward Step Test, and Balance with One Leg Standing. The values of each outcome measure were noted and assessed again after 15 days when they completed sitting for 3 hours each day. Result: The analysis shows a statistically significant difference between the outcome measures' pre and post-values. The Paired sample t-test was used to compare the data for which the Z value was negative, which confirms the post value was higher. The p-value was significant (p<0.05) at a 95% confidence interval. Conclusion: Prolonged sitting for 3 hours for 15 days resulted in a reduction in the physical fitness of the students. All three systems were compromised when assessed after 15 days, which says that due to prolonged sitting, flexibility, aerobic capacity, and balance are compromised, ultimately reducing the student's performance. Clinical Implication: The study says that the student's lecture shouldn’t continue for prolonged periods, and intermittent break is needed. As this affects the physical fitness of the students in upcoming years till they complete the degree, overall performance can be compromised to a greater extent. Self-awareness should be advised, and intermittent breaks with various stretches and exercises should be taught. Keywords: Prolong Sitting, Sit and Reach Test, Harvard Step Test, One leg standing.
