Squat Force Calculator

Formula

The formula to calculate the Squat Force (SF) is:

\[ SF = (LW + BW \times 0.90) \times g \]

Where:

\( SF \) is the squat force (N)
\( LW \) is the loaded weight of the bar (kg)
\( BW \) is the body weight of the lifter (kg)
\( g \) is the acceleration due to gravity (9.81 m/s²)

What is Squat Force?

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.

Example Calculation

Let's assume the following values:

Loaded Weight (LW): 100 kg
Body Weight (BW): 80 kg

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.
