Penerapan Biomekanika pada Alat Peraga Push Up

Abstract

Biomechanics is part of a scientific discipline that applies basic mechanical principles to explain the performance system in the human body (living things). One application in the human body is when doing push ups. Push up props are made to find out the relationship between arm length, mass, and angle to the force and torque. After the tool is assembled, the tool is experimented with mass manipulation variables 125 g; 290 g; 515 g and body length 20; 40; 60 cm. Based on the experimental results that the greater the arm's length, the greater the force and torque. The greater the mass of the object, the greater the force.

“…mengungkapkan semakin kecil sudut siku yang dihasilkan, maksimal gerak yang diberikan. Berbeda pendapat dengan penelitiMouromadhoni & Kuswanto (2019) semakin besar panjang lengan maka sekamik besar gaya yang di hasilkan dan semakin besar masa benda semakin besar gaya yang diberikan. Ruskin & Liputo (2021) mengemukakan panjang lengan mempengaruhi kecepatan pukulan yang di dominasi kekuatan otot lengan.…”
