Sharper change of direction angles (≥60°) and higher approach velocities significantly increase knee joint loading and injury risk due to greater braking forces and lateral ground reaction forces, creating a performance-injury conflict.
When coaching change of direction, recognize that sharper cuts (60 degrees or more) and faster approaches place significantly higher loads on the knees. To reduce injury risk, focus on strengthening the athlete's ability to produce force rapidly and improving their neuromuscular control, which helps them tolerate these higher loads safely.
faster and sharper CODs elevate the relative risk of injury due to the greater associative knee joint loading; however, faster and sharper directional changes are key manoeuvres for successful performance in multidirectional sport, which subsequently creates a ‘performance-injury conflict’ for practitioners and athletes.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
