18/5/2020, · With your arms and legs tucked tight to your body, your ,moment of inertia, is as small as it can possibly be so you spin at your fastest speed. By extending your arms and legs, you increase your ,moment of inertia,, slowing down and then cancelling your rotation so your body enters the water vertically, ideally without rotating.

Because of its greater size and mass, a ,helmet, will probably impact sooner and with greater force and greater turning ,moment, than a bare head. The Dutch research considered two impact speeds – 40 and 30 km/hr. Maximum head accelerations averaged 2033 and 1026 m/s² at 40 and 30 km/hr respectively; head injury coefficients (HIC) averaged 2556 and 548.
