The formula to calculate the Squat Force (SF) is:
\[ SF = (LW + BW \times 0.90) \times g \]
Where:
A squat force is the minimum force a lifter needs to exert on the ground to lift a certain weight during squatting. The squatting force depends on the weight loaded on the bar and also the person's body weight.
Let's assume the following values:
Step 1: Add the loaded weight to 90% of the body weight:
\[ LW + BW \times 0.90 = 100 + 80 \times 0.90 = 100 + 72 = 172 \text{ kg} \]
Step 2: Multiply by the acceleration due to gravity (9.81 m/s²):
\[ SF = 172 \times 9.81 = 1687.32 \text{ N} \]
The squat force is 1687.32 N.
