Dynamics of the basketball shot with application to the free throw     

Okubo H  Hubbard M 《Journal of sports sciences》2006,24(12):1303-1314

A completely general three-dimensional dynamic model is presented for the motion of basketball shots that may contact the rim, the backboard, the bridge between the rim and board, and possibly the board and the bridge simultaneously. Non-linear ordinary differential equations with six degrees of freedom describe the ball angular velocity and ball centre position. The model includes radial ball compliance and damping and contains five sub-models: purely gravitational flight, and ball-rim, ball-bridge, ball-board, and ball-bridge-board contact. Each contact sub-model has both slipping and non-slipping motions. Switching between the sub-models depends on the reaction force at, and velocity of, the contact point. Although the model can be used to study shots from any point on the court, we here use it to study the sets of free throw release angle, velocity, angular velocity, and lateral deviation angle that result in success (capture), as well as underhand free throws and those using an under-inflated ball. Free throw shots with larger backspin, lower inflation pressures, and underhand release conditions are shown to result in larger capture percentages.  相似文献   

The angiogenetic effect of intramuscular administration of b-FGF and a-FGF on cardiac muscle: the influence of exercise on muscle angiogenesis     

Efthimiadou A  Asimakopoulos B  Nikolettos N  Giatromanolaki A  Sivridis E  Lialiaris TS  Papachristou DN  Kontoleon E 《Journal of sports sciences》2006,24(8):849-854

Although angiogenetic therapy using recombinant growth factors holds much hope for the treatment of ischaemic diseases, there are still many unanswered questions, including the method of administration, the correct dose of these factors, and the duration of the therapeutic approach. Exercise has also been suggested to induce neovascularizaiton in muscles. We evaluated the angiogenetic effects of the intramuscular administration of basic-fibroblast growth factor (b-FGF) and acidic-fibroblast growth factor (a-FGF) in rat heart, compared with rats who exercised daily. In conclusion, both the intramuscular administration of b-FGF and exercise increased significantly angiogenesis in the heart in contrast to the intramuscular administration of a-FGF, which was ineffective.  相似文献   

Maintaining Discipline in the Kaiser Wilhelm Society during the National Socialist Regime     

Richard H. Beyler 《Minerva》2006,44(3):251-266

In responding to incidents of internal ‘indiscipline’, the Kaiser Wilhelm Society many times asserted its authority, sometimes in cooperation with agencies of the Nazi regime. Following the Second World War, however, the KWS represented itself as having been intrinsically anti-Nazi. This essay describes the assumptions inherent in this view, and points to its wider implications for post-war German science.  相似文献

The Model American Foundation Officer: Alan Gregg and the Rockefeller Foundation Medical Divisions     

Schneider  William H. 《Minerva》2003,41(2):155-166

From 1919 to 1951, Alan Gregg and his mentor, Richard Pearce, directed the Medical Education and Medical SciencesDivisions of the Rockefeller Foundation. Although they oversaw the expenditure of millions of dollars, today they are forgotten. Yet, the system that Gregg administered became the model for the funding of biomedical research after the Second World War. This paper draws on the records of the Rockefeller Foundation to assess Gregg and his impact on biomedicine and philanthropy.  相似文献
