In ambito sportivo l’analisi del movimento, attraverso la quale è possibile analizzare la biomeccanica del movimento degli atleti, può essere fondamentale. La ricerca di parametri che possano spiegare le prestazioni, può essere utile ad allenatori e atleti per identificare i fattori della tecnica migliore e quindi massimizzare la prestazione degli atleti o ridurre il rischio di infortuni, individuando problemi di asimmetria o errori nel movimento della corsa. Lo studio si concentra su 22 atleti, velocisti sui 100 metri; ogni atleta ha partecipato a due sessioni, una per le partenze ed una per il lanciato. I dati sono stati raccolti presso il Palaindoor di Padova attraverso il sistema di analisi Motion Capture con delle Piattaforme di Forza e delle Fotocellule. Successivamente sono stati elaborati con il software Vicon Nexus. I parametri cinetici sono stati estratti nello Smart Track Analyser BTS e i parametri cinematici sono stati ottenuti nel software MATLAB. In MATLAB tutti i dati sono stati raccolti in un unico Excel con una riga per ogni test dell'atleta, con un foglio diverso per partenze e lanciati. Infine, è possibile analizzare le traiettorie dei marker, degli angoli, delle forze in Smart Track Analyser o in MATLAB o in Excel. L'analisi è focalizzata sui parametri cinetici e cinematici. I parametri acquisiti sono stati decisi con gli allenatori e studiando la letteratura con l’obiettivo di ricercare i parametri che meglio spieghino la variabilità della velocità degli atleti. I dati ottenuti sono stati infine analizzati con JASP, software statistico, con Regressione Lineare Multipla e Correlazione. Il risultato delle partenze mostra che i parametri più importanti sono la velocità all'uscita dai blocchi e l'angolo di spinta all'uscita dai blocchi, l'angolo tra la gamba e l'orizzontale. Inoltre la componente orizzontale massimizza quella propulsiva e minimizza quella frenante. Il risultato del lanciato è simile e mostra l'importanza dei parametri cinetici durante il lanciato; non è determinante la componente verticale, ma fondamentale quella orizzontale come differenza tra componente propulsiva e frenante.

Abstract
In the sport field the movement analysis, through which it’s possible to analyse the biomechanics of movement of the athletes can be fundamental. Searching for parameters that can explain the performances can be useful for coaches and athletes to identify the factors of the best technique and then to maximise the performance of the athletes or to reduce the risk of injures, identifying problems of asymmetry or errors in the running movement. The study focuses on 22 athletes, 100 meters sprinters; each athlete participates at two sessions, one for starts and one for flying. The data are collected at Palaindoor of Padua through Motion Capture analysis system, Force Platforms and Photocells. Then they are processed with Vicon Nexus software. The kinetic parameters are extracted in Smart Track Analyzer BTS and kinematic parameters are obtained in MATLAB software. In MATLAB all data are collected in a unique Excel with a row for each run of the athlete, with different sheet for starts and flying. Finally, it’s possible to analyse the trajectories of the markers, of the angles, of the forces in Smart Track Analyzer or in MATLAB or in Excel. The analysis is focused on kinetic and kinematic parameters. Parameters acquired are decided with the coaches and by studying literature with the aim of search for the parameters that explain better the variability of the athletes’ velocity. The data obtained are analysed with JASP, statistical software, with Multiple Linear Regression and Correlation. The result of starts shows that the most important parameters are the velocity at block clearance and push angle at block clearance, the angle between the leg and the horizontal. Moreover, the horizontal component maximise the propulsive one and minimize the braking one. The result of flying is similar and shows the importance of kinetic parameters during flying; it’s not determinant the vertical component, but it’s fundamental the horizontal one with the difference between propulsive and braking components.File | Dimensione | Formato | |
