How to stop animation while in certain humanoidstatetype?

I want to stop this sprinting animation while I am jumping or falling but it does not seem to work. Here is code where I want it to check for the state and stop the script...

while true do
    wait()
    if Enum.HumanoidStateType.Jumping or Enum.HumanoidStateType.Freefall then
    sprintAnim:Stop()
    end
end

Not sure if this is a mistake or another piece of code in my local script is preventing it on working. Please help and explain I am new to scripting and still learning. Thanks :) Code for sprinting

-- Sprint Key Pressed
userInputService.InputBegan:Connect(function(input)
    if input.KeyCode == Enum.KeyCode.LeftShift then
        if currentStamina >= staminaCost and character.Humanoid.MoveDirection.Magnitude > 0 then
            character.Humanoid.WalkSpeed = sprintSpeed
            sprintAnim:Play()
        end
    end
end)
