Following approval from the institutional ethical committee, an invite to participate in the study will be sent to the research scholars. A detailed explanation of the study objectives and procedures will be provided, and written informed consent will be obtained from all participants prior to enrolment. Eligible participants, based on the predefined inclusion and exclusion criteria, were then organized into study groups. The assessment protocol began with evaluation of forward head posture using the Craniovertebral Angle (CVA), measured via standardized lateral-view digital photographs analyzed using Kinovea Software (Version 2023.1.1). Anatomical landmarks—the C7 spinous process and the tragus of the ear—were marked, and a horizontal line was drawn from C7, with another line extending from C7 to the tragus. The angle formed between these lines was recorded, and the mean of three trials was used for analysis. Participants also provided a subjective self-report of their average daily sitting duration over a 7-day recall period, including academic, recreational, and screen-based activities. Subsequently, the strength of the gluteus maximus muscle was measured using the Biodex System 3 Isokinetic Dynamometer. Participants performed isokinetic contractions of hip extension, abduction, and adduction in the prone position, following standard manufacturer protocols. Additionally, rounded shoulder posture (RSP) was assessed by measuring the vertical distance from the acromion to the plinth in the supine position. All data were systematically recorded and compiled into a master chart for statistical analysis to investigate the relationship between sitting duration, postural deviations (such as forward head posture), and gluteus maximus muscle strength.
