(1) Prepare. First of all, we should prepare a suitable air pump and nozzle. The air pump needs to be connected to the basketball valve. You also need to confirm the current air pressure, which is usually marked on the ball. If you are not sure, you can measure it with a barometer.

(2) the pumping process. Insert the air nozzle into the basketball air hole and tighten the air nozzle. Use an air pump to inflate the basketball, and at the same time, the attention and frequency should be appropriate to avoid the air pressure being too high or too low.

(3) Check the air pressure. Check whether the air pressure meets the requirements in time after pumping. You can check it with a barometer or by hand.

(4) keep basketball. After the gas is used up, the gas nozzle should be tightened in time to avoid gas leakage. At the same time, we should also pay attention to avoid excessive friction and sun exposure and protect the surface material of basketball.

(5) Precautions for supplementary pumping. Breathe a few times before playing to ensure the elasticity and feel of basketball. At the same time, it is necessary to avoid high-temperature inflation and prevent the spherical shell from bursting due to excessive expansion of gas. Avoid pumping air in cold environment to avoid unstable air pressure.

Some tips for playing basketball are as follows:

When shooting, you should use the slight rebound of your palm to control your strength. Pay attention to the direction when passing the ball, and try not to throw the ball at the opponent. When dribbling, don't use your palm too hard, which will affect your feel.
