KNEE INJURY PREVALENCE IN KARACHI GYMS

Abstract

Introduction: Acute knee injuries are common among individuals engaged in physical fitness routines, particularly females who are increasingly participating in gym-based activities. Factors such as poor biomechanics, inadequate warm-up, overuse, and improper technique contribute significantly to injury occurrence. This study aimed to determine the prevalence of acute knee injuries and identify associated risk factors among female gym members in Karachi.

Methodology: A cross-sectional study was conducted among 200 female gym-goers in Karachi aged 18–40 years. Data on demographics, training patterns, type and intensity of exercises, use of protective equipment, history of previous injuries, and presence of knee pain or injury were collected using structured questionnaires and clinical assessment tools. Descriptive statistics were used to analyse prevalence. Chi-square and logistic regression tests were applied to assess the association between risk factors and injury occurrence.

Results: The prevalence of acute knee injury among female gym members was found to be 38.5%. High-impact workouts (62.3%), lack of professional supervision (58.7%), poor footwear (47.1%), and inadequate warm-up routines (43.8%) were the most reported risk factors. A statistically significant association was found between high-intensity interval training (HIIT) and acute knee injury (χ² = 12.49, p < 0.01), as well as previous history of lower limb injury (χ² = 15.68, p < 0.001).

Conclusion: Acute knee injuries are prevalent among female gym members in Karachi, with modifiable risk factors such as improper technique, insufficient warm-up, and lack of guidance playing a major role. Structured prevention strategies including proper training education, injury screening, and supervision by certified trainers are essential to reduce the risk and enhance workout safety.
