In a large sample of both male and female athletes, subdivided by age sex, development curve isometric muscule force (F) was analyzed for hand flexors, upper-body flexors extensors, knee extensors (PDS). A 1,857 1,009 aged 8-30 years, their used to measure the mean values muscle certain groups way 5 topologically defined tests. Based on results, curves are shown right-hand left-hand (PLS) (PTR), (OTR), (ONO). The application statistical programs gave rise equations relationship between age....

Abstract This paper introduces an equation for determining instantaneous and final velocity of a sprinter in 100 m run completed with wind resistance ranging from 0.1 to 4.5 m/s. The validity the was verified using data three world class sprinters: Carl Lewis, Maurice Green, Usain Bolt. For given constant values + 0.9 1.1 m/s, contribution change same maximum as well velocity. study assessed how effect influenced sprinting analysis led conclusion that official limit safely neglecting...

Introduction. In the treatment of various orthopedic conditions, regenerativetherapies, including platelet rich plasma and autologous stem-cell therapy, have recently been advancing. Knee cartilage lesions are a debilitating disease resulting in fibrillation subsequent degradation which can also involve subchondral bone lead to development osteoarthritis. Bone marrow mesenchymal stem cells heterogeneous mixture involved formation regenerative repair, whereas other capacity play role as...

Abstract The aim of the research was to provide an analytical expression for final time and velocity at 100 m run, taking into account realistic conditions more precisely effect wind resistance medium (air). Combining polynomial model distance vs with solution algebraic cubic equation, such derived. allowed evaluate dependence race on velocity. This enabled quantification mentioned influences It is possible calculate sprinter’s expired running various velocities (from 0 up ± 10 m/s) as well...
