The pivotal axis defining means may be a pivot pin.
The adjustment means may comprise an adjustment screw receivable in a threaded opening defined in an extension flange of the second support element.
The extension flange may extend beyond an operatively bottom edge of the second support element so that the adjustment screw abuts against a rear surface of the first support element.
The starting block may further include a setting means for setting the angular position of the first support element relative to a substrate.
According to a second aspect of the invention, there is provided an accessory for a starting block, the accessory including a heel-support member for supporting a user's heel; and a mounting means for mounting the heel-support member on a part of the starting block.
