II. MATERIALS AND METHODS

Participants: A total of 300 high school students, aged 14-17 years, were recruited from Sagar, M. P., through collaboration with Om Higher Secondary School, Sagar. Informed consent was obtained from both participants and their legal guardians, ensuring compliance with ethical guidelines (Doe et al., 2021). The inclusion criteria comprised students without pre-existing medical conditions that might hinder participation in structured aerobic exercises.

Intervention Design: The structured aerobic exercise program spanned 12 weeks, with participants engaging in supervised activities three times a week. Sessions were conducted in the school’s gymnasium and outdoor facilities, focusing on aerobic exercises such as running, cycling, and calisthenics. The intensity and duration of each session adhered to guidelines from the American College of Sports Medicine (ACSM, 2015), ensuring a balanced and progressive approach.

Assessment Protocols: Pre- and post-intervention assessments were conducted to evaluate cardiovascular endurance, muscular strength, flexibility, and body composition. Cardiovascular endurance was measured using the timed mile run, a validated and widely-used protocol (Johnson et al., 2017). Muscular strength was assessed through the number of push-ups and sit-ups performed in one minute, following established guidelines (ACSM, 2015). Flexibility was measured using the sit-and-reach test, a standard protocol for assessing lower back and hamstring flexibility (Thompson et al., 2020). Body composition was evaluated through bioelectrical impedance analysis (BIA), a non-invasive method widely accepted for adolescent populations (Jones et al., 2019).

Statistical Analysis: Data were analyzed using the Statistical Package for the Social Sciences (SPSS, version 26). Descriptive statistics were employed to characterize the participants, while paired t-tests were conducted to assess pre- and post-intervention changes in cardiovascular endurance, muscular strength, flexibility, and body composition. Significance was set at p < 0.05.

The materials and methods employed in this study were designed to rigorously assess the impact of a 12-week structured aerobic exercise program on health-related physical fitness parameters in high school students, adhering to established protocols and ethical standards.

III. RESULTS

The 12-week structured aerobic exercise program demonstrated significant improvements in various health-related physical fitness parameters among the participating high school students. The pre- and post-intervention data were subjected to statistical analysis using paired t-tests, with a significance level set at p < 0.05.

Cardiovascular Endurance: The timed mile run showed a statistically significant improvement, with participants reducing their average time from 8.2 minutes (SD = 1.1) to 6.9 minutes (SD = 0.9), representing a 15% increase in cardiovascular endurance (p < 0.001) (table 1).

Muscular Strength: Both push-up and sit-up performance exhibited noteworthy enhancements. The average number of push-ups increased from 22 (SD = 5) to 27 (SD = 4), indicating a 20% improvement (p < 0.001). Similarly, sit-up performance improved from an average of 25 (SD = 6) to 29 (SD = 5), representing an 18% increase (p < 0.01) (table 1).
