Abstract: This study investigated the mechanisms of metatarsal cellular mechanical stress responses to plantar pressure during basketball activities. A comprehensive analysis was conducted using integrated biomechanical and cellular approaches, involving 120 professional basketball players divided by playing positions. Plantar pressure distribution was measured during specific basketball movements using a high-precision pressure measurement system, while cellular responses were analyzed through morphological, biochemical, and genetic markers. Results demonstrated a non-linear relationship between applied pressure and cellular stress response, with a threshold effect at 300 kPa. Significant position-specific differences were observed in pressure distribution patterns, with centers exhibiting higher peak pressures (698.3 kPa ± 52.4 kPa) compared to forwards (642.5 kPa ± 48.6 kPa) and guards (584.2 kPa ± 42.3 kPa). Cellular adaptation mechanisms showed peak activity between 24–48 hours post-stimulation, characterized by increased aspect ratios and upregulation of mechanosensitive genes. Multiple regression analysis identified peak pressure, loading duration, and recovery time as primary factors influencing cellular responses, accounting for 85% of observed variance. These findings provide novel insights into the relationship between basketball-specific mechanical loading and cellular adaptation mechanisms, offering implications for injury prevention and training program optimization.
