Does holding certain objects in your hand change your movement speed?

I was wondering, are there any movement speed differences if you hold specific objects in your hand?

I'm interested even in a small movement speed difference, like, in decimals.

Solution 1:

There are no objects or items that affect your movement speed while held, but there are certain objects that will affect your movement speed when used:

• When thrown, ender pearls will teleport you to the location at which they land (1.9-pre2+)
• You can craft potions of swiftness that will increase your speed for a short period of time (1.9-pre3+)

There are also environmental effects and actions that modify your movement speed:

• Walking on soul sand
• Using a Minecart
• Swimming in water
• Sneaking
• Sprinting
• Riding in a boat
• Explosions and TNT Cannons (assuming you live)
• Walking through cobwebs
• Walking across ice
