Abstract: 
This study investigated the effects of body mass and shoe midsole hardness on kinetic and perceptual variables during the performance of three basketball movements: (i) the first and landing steps of layup, (ii) shot-blocking landing and (iii) drop landing. Thirty male basketball players, assigned into ‘heavy’ (n=15, mass 82.7±4.3kg) or ‘light’ (n=15, mass 63.1±2.8kg) groups, performed five trials of each movement in three identical shoes of varying midsole hardness (soft, medium, hard). Vertical ground reaction force (VGRF) during landing was sampled using multiple wooden-top force plates. Perceptual responses on five variables (forefoot cushioning, rearfoot cushioning, forefoot stability, rearfoot stability and overall comfort) were rated after each movement condition using a 150-mm Visual Analogue Scale. A mixed factorial analysis of variance (Body Mass×Shoe) was applied to all kinetic and perceptual variables. During the first step of the layup, the loading rate associated with rearfoot contact was 40.7% higher in the ‘heavy’ than ‘light’ groups (P=.014) and 12.4% higher in hard compared with soft shoes (P=.011). Forefoot peak VGRF in soft shoe was higher (P=.011) than hard shoe during shot-block landing. Both ‘heavy’ and ‘light’ groups preferred softer to harder shoes. Overall, body mass had little effect on kinetic or perceptual variables.
