Evaluation of Cardiorespiratory Fitness and Core Endurance Among Young Adults of Rawalpindi & Islamabad

Objective: The objective of this study is to evaluate the core endurance and cardiorespiratory fitness among the young adults of Rawalpindi and Islamabad. Study Design: A descriptive cross-sectional study was conducted. Place and duration of study: The study design of this study was descriptive cross sectional which was done in community of Rawalpindi & Islamabad from February 2024 to January 2025. Material and Methods: The study design of this study was descriptive cross sectional which was done in community of Rawalpindi & Islamabad from February 2024 to January 2025. Non probability purposive sampling technique was done on young adults of age 20-35 years. Core endurance was evaluated using Mc Gills test while cardiorespiratory fitness was determined through YMCA 3 minute step test and physical activity levels via IPAQ. SPSS v.21 was used data analysis. Mean±SD was used to express the quantitative variables while to compare the groups Kruskal Wallis test was applied. Results: The study recruited 450 young adults which were equally distributed (n=150) among three activity levels (mild, moderate and vigorous). The score (19.53 ± 1.95) of Trunk Flexor Endurance Test was less in the mild physical activity category, contrary to the vigorous physical activity category which demonstrated the greatest score of (30.21 ± 1.69). Correspondingly, mild physical activity group had lowest value (8.25 ± 1.29) and vigorous physical activity group had a peak value (19.13 ± 1.72). Similar trend was seen in mild physical activity group with regard to the Left Sided Trunk Lateral Endurance Test which experienced the lowest score (8.17 ± 1.39) than vigorous physical activity group having the highest one (18.85 ± 1.77). The mild group attain the low value (4.53 ± 1.13) for Test of Trunk Extensor Endurance while the highest score (15.05 ± 1.44) was exhibited by vigorous physical activity group. The trend present in the mild physical activity group with regard to VO2max was lowest (46.23 ± 6.55) and in the vigorous physical activity group it was highest (74.23 ± 3.73). Moreover, the heart rate found to be highest (139.96 ± 3.09) in the mild physical activity group whereas the lowest heart rate (119.53 ± 5.05) was present in the moderate physical activity category Conclusion: The study concluded that the physical activity impact on young adults demonstrated that individuals involved in vigorous activity have improved cardiorespiratory fitness along with good core endurance than those involved in mild activity and moderate activity category
