Mathematics vertebral. We can cite some movements that rely on our center of gravity, such as the execution of the service in a volleyball match; physical actions required in a handball match, running, jumping and falling athletes jumping distance; strength alterofilista to raise the bar; jump athlete to transpose the height of the stick in the high jump and running, dribbling, hat, defense and kicking a soccer match. Another example is the jump barrier. One of the applications of the CG body is the jump of the athlete by the barrier. When a hurdler loses contact with the ground, after the use of force for the jump, the trajectory of its CG is defined. However, according to the body movement, the GC takes different paths. This can be seen in figure 6. If at the time the body is in the air, as illustrated in Figure 7, the runner raising his trunk consequently takes their body mass up and therefore its CG. But this increase does not mean that change occurs in the trajectory of CG, because our body does not contradict the laws of physics. Actually, what happens is the rise of the CG relative to the body of the hall. If the body down in relation to the trajectory of the CG as a result the athlete will struggle to pass the barrier. Lean your torso forward, your lower CG to the body. This represents the rise of the body relative to the path of the CG, which facilitates the passage of the leg and reduce air resistance. As a result, decrease the chance of colliding with the barrier. can say that minimizes fluctuation of CG in the sagittal plane and allows the runner, run so successful jump.

Matematika kralješnice. Možemo navesti neke pokrete koje se oslanjaju na naše težišta, kao što izvršenja usluge u pijesku odgovarati, fizičke aktivnosti potrebne u rukometnu utakmicu, trčanje, skakanje i pada sportaša skakača udaljenost; Snaga alterofilista podići ljestvicu; skok sportaš transponirati u visini od palice u skoku u vis i trčanje, vođenje, kapu, obranu i udaranje nogometne utakmice. Drugi primjer je skok prepreka. Jedna od primjena u CG tijela je skok od sportaša od strane barijere. Kad preponama izgubi kontakt sa zemljom, nakon uporabe sile za skok, putanja njegova težišta tijela se definira. Međutim, u skladu s pokretima tijela, GC ima različite staze. To se može vidjeti na slici 6. Ako u to vrijeme tijelo je u zraku, kao što je prikazano na slici 7, drugoplasirani podigavši prtljažnik posljedično vodi svoju tjelesnu masu i time svoju CG. No, to povećanje ne znači da je došlo do promjene putanje težišta tijela, jer naše tijelo ne proturječi zakonima fizike. Zapravo, ono što se događa je porast od CG u odnosu na tijelo u dvoranu. Ako tijelo prema dolje u odnosu na putanju CG kao rezultat sportaš će se boriti da prođe barijeru. Nagnite torzo naprijed, donji CG na tijelu. To predstavlja povećanje od tijela u odnosu na naprijed prema GK, što olakšava prolaz nogu i smanjiti otpor zraka. Kao rezultat toga, smanjuju šanse sudara s preprekom. može reći da smanjuju fluktuaciju CG u sagitalnoj ravnini, a omogućuje trkač, izvoditi tako uspješan skok. Što Matematika je prisutan u brodice?
