Baseball Pitchers

Pitchers, improve your performance between innings by using our cold/hot recovery sleeve that uses negative pressure compression. Perfect for the dugout between innings.


Intended Use

  • To improve your athletic performance by removing heat fatigue from the pitcher’s arm between innings. The temperature altering sleeve may improve pitcher’s endurance by delaying the onset of fatigue when throwing a baseball.
  • Our negative pressure compression sleeve will fit you tightly and help your arm feel good. It will also accelerate the rate of cooling through the palm.
  • Use cold to improve endurance by reducing fatigue. Use heat to re-warm your hands and stimulate blood flow before throwing.

Directions – How to Use

  1. Prepare. Refrigerate cold packs to 40-50 °F before use. If applying heat, active your heat pack 30 minutes before use per their instructions.
  2. Apply heat pack to the palm of the pitching hand, and insert both into the recovery sleeve (logo facing out) before you start throwing. Switch to cold between innings to extend your endurance during games and in hot humid conditions.
  3. Make sure you secure the top of the sleeve with attached strap to prevent air from escaping and to seal the negative pressure compression recovery sleeve.
  4. Make sure you use the suction squeeze pump until air is completely removed from inside the sleeve.
  5. Make sure you periodically squeeze the squeeze pump to remove air and hold the negative pressure compression.
  6. Grab a new 40-50°F cold pack every inning in the dugout. Apply heat before you resume throwing. Start approximately 5 min cold, and then end roughly 2 min warm. (Highly individualized-use what works best for you)
  7. Repeat as needed. Post-workout or post pitching appearance finish cold for recovery. Warm for adaptation. 5-15 minutes recovery duration. Apply on your pitching arm.

Please note

  • Cold packs should NOT be frozen or applied at a temperature colder than 40°F. This will cause the capillaries in the palm to constrict, which will prevent the removal of heat.
  • Cold packs are good for 5-10 minutes (or until 64°F), then should be switched for a new one.
  • Heat packs are good for roughly 10 hours. The heat packs may take up to 30 minutes to heat activate. While the temperature between the heat packs may vary between 100-160°F. Remove immediately if too hot.
  • Seal the recovery sleeve at the top of the arm and make sure that no undershirts prevent a complete seal. Otherwise air will leak and prevent negative pressure compression.

-Study on Cooling Between Innings:

Eight amateur male baseball pitchers applied 4 minutes of wet ice cooling to their forearms and shoulders between innings which resulted in an increase in average pitch speed over 5 innings (12 max effort pitches per inning). The greatest increase in average pitch speed occurred in the 4th and 5th innings when using the cooling intervention. This shows that intermittent cryotherapy can slow the loss of velocity in pitchers as pitch counts rise. The use of intermittent cooling between innings also improved the pitchers perceived recovery and rate of exertion. The authors note that pitchers typically wear towels or a jacket on their pitching arm to keep the arm loose and warm, but this practice contradicts the current scientific evidence.
