There are several things you can do to better prepare yourself for actual competition. A few simple adjustments can be made in your training routine and approach so you will feel more ready for the conditions you will face in the ring.
Change the size of your training gloves leading up to the fight. A solid pair of sixteen or eighteen ounce training gloves offer great protection and coverage during gym work and sparring, but they’re a bigger size (almost double in some professional scenarios) and more weight than you actually fight in. For the final week of real training, switch to a pair of actual lightweight, competition gloves, closer to what you fight in. Shadowbox with them on, hit the bag and even do some light sparring (very light) to get used to how they affect your punches. Obviously, there’s a distinct difference in 8 ounce professional fight gloves and 16 once sparring gloves, so the switch will slightly affect your speed, timing and punching power. The weight of the gloves you compete in can have a fairly significant impact on what happens in the ring, so it requires and deserves some getting used to. The overall idea is to get acclimated to as many variables that come into play during actual competition BEFORE you have to experience them for real. That way there are fewer unknowns and new sensory influencers to face at a time when you are already dealing with a heightened, emotionally-charged experience. Anything you can do to familiarize yourself with actual “fight feelings”, the better you will be able to then focus on the new stimuli you encounter.
