Background: Studies on the relationship between performance and design of the throwing frame have been limited. Part I provided only a description of the whole body positioning. Objectives: The specific objectives were (a) to benchmark feet positioning characteristics (i.e. position, spacing and orientation) and (b) to investigate the relationship between performance and these characteristics for male seated discus throwers in F30s classes. Study Design: Descriptive analysis. Methods: A total of 48 attempts performed by 12 stationary discus throwers in F33 and F34 classes during seated discus throwing event of 2002 International Paralympic Committee Athletics World Championships were analysed in this study. Feet positioning was characterised by tridimensional data of the front and back feet position as well as spacing and orientation corresponding to the distance between and the angle made by both feet, respectively. Results: Only 4 of 30 feet positioning characteristics presented a coefficient correlation superior to 0.5, including the feet spacing on mediolateral and anteroposterior axes in F34 class as well as the back foot position and feet spacing on mediolateral axis in F33 class. Conclusions: This study provided key information for a better understanding of the interaction between throwing technique of elite seated throwers and their throwing frame.

EM artigo anteriormente publicado (AGUIAR, 2008a), concluímos que as críticas elaboradas por certos autores (SOUSA, 2000; KURTZ, 1993; MARSHALL, 2003; MARCONDES FILHO, 1988), ao classificarem um determinado modo de jornalismo como sensacionalista, parecem querer opor uma imaginária constituição democrática do espaço público e da cultura legítima a uma suposta disfunção narcotizante do entretenimento, que promoveria o conformismo social e reforçaria as normas sociais. O jornalismo sensacionalista, nesse entendimento, veicularia apenas a ampla trivialidade e o excesso de diversão estaria “matando” os ideais iluministas da sociedade moderna, tal como aposta Postman (1986). Entretanto, pode-se ver nestas críticas aquilo que Edgar Morin define, ao estudar cultura de lazer, como a má impressão causada pelo divertimento e pela evasão aos “moralistas dessa confederação helvética do espírito que são as letras e a universidade” (MORIN, 2002).
