Prolong Sitting, Sit and Reach Test, Harvard Step Test , One leg standing.



Background: The prolong sitting has adverse effects on body’s physical fitness. Since the students are sitting in college during lecture hours, their physical fitness is being compromised. There are studies that have proved that inactivity can affect various systems.

Method: The study included 50 students randomly whose age ranged between 18-22 years college going.. The students were then assessed for the flexibility with Sit and reach test, for aerobic capacity with Harward Step Test and for Balance with One Leg Standing. The values for each outcome measure were noted and were assessed again after 15 days when they completed sitting for 3 hours each day.

Result: The analysis show statistical significant difference between and pre and post values of all the outcome measures. The Paired sample t test was used to compare between the data for which Z value was negative which confirms the post value were more. The p value was significant (p<0.05) at 95% confidence interval.

Conclusion: Due to prolong sitting for continues 3 hours for 15 days resulted in reduction in the physical fitness of the students. All three systems was compromised when assessed after 15 days which says that due to prolong sitting, the flexibility, aerobic capacity and balance gets compromised which ultimately reduced the performance of the student.

Clinical Implication:  The study says that the students lecture shouldn’t continue for prolong period of time and intermittent break is needed. As this affects the physical fitness of the students with upcoming years till they complete the degree overall performance can be compromised to greater extent. For which various self awareness should be advised and intermittent breaks with various stretches and exercise should be taught.
