During weightlifting, a lifter strains to complete a bench press rep. Which failure mode becomes likely when the force demands exceed the biomechanical limits of the shoulder joint?

💡 Explanation

Glenohumeral joint subluxation is likely because the extreme forces overwhelm the joint's stability mechanisms, especially the rotator cuff muscles and ligaments. Therefore, the humerus partially dislocates from the glenoid fossa, rather than increased bone formation or other joint-related adaptive processes.

• In type 2 diabetes, why does hyperglycemia persist despite elevated insulin levels following a carbohydrate-rich meal?
• A novel COVID-19 vaccine uses mRNA to present viral proteins along with an adjuvant. Which mechanism explains why a second dose is typically administered weeks after the first?
• Why does insulin resistance often develop in obese individuals with chronically elevated blood glucose levels?
• As individuals age, the risk of sarcopenia increases, leading to reduced muscle mass and strength. Why does age-related decline in satellite cell function contribute significantly to this condition?
• If a patient with long-term type 2 diabetes develops resistance to insulin signaling in muscle cells, which consequence is most likely?
