Unsupervised Exercise Linked to Injuries in Obese Individuals, Experts Warn

Two recent cases and a growing body of research highlight the risks of strenuous, unsupervised exercise for individuals with obesity, potentially leading to musculoskeletal injuries and cardiovascular strain.

Anshul, a 16-year-old with a body mass index of 42, developed a stress fracture in his shin bone after jogging daily for an hour over two months to lose weight. Similarly, Priya, 35, with a BMI of 38, experienced worsening knee pain and cartilage thinning after three years of daily 45-minute treadmill workouts. Both cases, according to specialists, demonstrate how the skeletal system can be overloaded by excessive weight and prolonged, unmonitored physical activity.

Experts emphasize that obesity—defined as a Body Mass Index of 25 or above—carries significant health risks, including diabetes, hypertension, heart disease, and certain cancers. According to the National Family Health Survey-5 (2019-21), approximately 24 percent of the Indian population is obese, a figure that is rising due to sedentary lifestyles and poor diets. This increase in obesity rates places a greater strain on healthcare systems and underscores the need for preventative measures. The survey also revealed a significant increase in overweight children under 5, indicating a growing public health concern. A three-pronged approach—diet, physical activity, and controlled exercise—is recommended for safe and effective weight management.

The increased demands on the cardiovascular system during exercise, coupled with potential comorbidities like hypertension, can exacerbate risks for obese individuals. Furthermore, the mechanical load on bones and joints is disproportionately high, increasing susceptibility to injuries like stress fractures and osteoarthritis. As detailed in a recent report on obesity and exercise, progressive overload and supervised training are crucial to mitigate these risks.

Health officials advise a cautious and supervised approach to exercise for individuals with obesity, emphasizing the importance of dietary changes and gradual increases in physical activity.
