Abstract

Vježbanje slobodnim utezima jedan je od najčešćih načina vježbanja te ga ne koriste samo profesionalni sportaši i treneri, već i početnici, rekreativci i mladi ljudi. Vrlo je bitno smislenom biomehaničkom analizom pokreta pri vježbanju slobodnim utezima utvrditi ograničenja i preporuke zbog toga što nepravilnim izvođenjem može doći do ozbiljnih ozljeda. Biomehanička analiza izvršena je za pet temeljnih vježbi uz posebno obraćanje pažnje na trajektoriju šipke u sagitalnoj ravnini te međusobne položaje i kuteve između određenih segmenata tijela i zglobova. Iz rezultata analize je zaključeno na što treba obratiti pozornost, koje su značajke uspješne i djelotvorne primjene te su ukazane najčešće nepravilnosti i kako ih ispraviti. Dobivene trajektorije šipke ukazale su na neodgovarajuće izvedbe određenih naprava i pomagala za vježbanje, no također su pokazale mogućnosti poboljšanja istih. Uz to, biomehaničkom analizom dobila se podloga za definiranje željenih značajki opreme i sprava za vježbanje. Pregledom tržišta uočena je naprava za vježbanje koja bi zadržala prednosti vježbanja slobodnim utezima uz pružanje veće razine sigurnosti – Smith mašina. Sažetom analizom ukazani su nedostaci te sprave te je na kraju dano konceptualno rješenje koje bi poboljšalo njenu primjenu.

Abstract (english)

Free weights training is one of the most common ways of working out and it is not only used by professional athletes and trainers, but also by beginners, amateurs and young people. It is very important to determine limitations and recommendations with a biomechanical analysis of movements in free weights training, because serious injuries can occur if exercising is done incorrectly. Biomechanical analysis was carried out for five compound exercises with special attention to bar trajectory while looking from the sagittal plane and relative positions and angles between certain body parts and joints. It was concluded, from the results of the analysis, which things should especially be looked out for and what are the features of successful and effective application. Also, the most common mistakes were pointed out and ways to correct them were given. Obtained trajectories pointed out the inadequate construction of certain machines and gym equipment, but they also go to show that there is a way to improve said equipment. Biomechanical analysis also provided a base on which to define wanted features of the exercising equipment. While researching the existing exercising solutions a certain machine was noticed that keeps the benefits of free weights training while providing a higher level of security – the Smith machine. Some disadvantages of the Smith machine were given by a brief analysis. Thus, at the end, a conceptual solution of an improved Smith machine was given which would improve its use.
