In a conversation with former LPGA player, Sue Kim (Canada) related how she had a problem with drinking on the course; “I would never drink enough during a tournament. I simply forgot to drink”. Her solution? Kim modified her pre-shot routine. Arriving at the next shot, her routine began with a few sips of water. It helped her to maintain a hydrated state during a round and the action became automatic, ensuring she didn’t forget to drink. General Advice: • As a guide, 13-16 year olds need 1.6-1.9L of total fluid each day (from food and fluids). Exercise will increase this amount. • Be prepared – bring adequate water with you to the course/practice range. There may not always be opportunities for purchasing water when you need it (e.g., ninth hole). • Be aware, thirst may not be a good indicator of how dehydrated you are. • Develop your own customized fluid replacement strategy and evaluate in training first before attempting it during a tour nament. • Consuming fluids before exercise • Aim to start your practice/tournament in a well- hydrated state – check your urine color (ideally it should be pale yellow). • Consume 5-10ml/ kg BW water prior to exercise (i.e., 120 lbs. or 55kg = 275-550ml or 8-16 fluid oz.) • Consider including sodium in foods/fluids may be useful as it will help you to retain fluid during exercise. • During Exercise • Aim for 0.4-0.8 L of fluid per hour (130-250ml every 20 minutes). • Water is the number one choice for fluid replacement in most instances. • Consume small volumes of fluid frequently throughout the exercise/round/practice. • Avoid over-drinking. A condition called Hyponatremia (low blood sodium level) is the risk of consuming too much water, with symptoms shockingly similar to dehydration. • Recommendations are to consume enough fluid to minimize loss of body mass (1-2% loss) • There may be a case for sports drinks in certain circumstances when a source of carbohydrates and electrolytes (primarily sodium) are required (e.g., when access to food is limited). • Cold drinks may help to reduce core body • • • • temperature during exercise in the heat and increase the tendency to consume more fluid. Flavored waters may also increase consumption. Avoid energy drinks at all costs! Recovery The goal is to drink to 150% of the fluid lost during exercise (based on weight). Yes, more than you lost; this accounts for the obligatory urinary losses. Eat a meal post-practice/tournament – it will provide the carbohydrates, protein and electrolytes (Sodium and Potassium) necessary for recovery. The optimal strategy for fluid intake for young golfers will vary based on numerous factors including climatic conditions, the opportunity to eat/drink, gastrointestinal comfort and an individual’s own physiology and biochemistry. Thus, consider the hydration recommendations provided and work on developing your own customized hydration strategy for both practice sessions and tournament rounds. It should be considered an essential element of a golf athlete’s preparation. References: American Academy of Pediatrics (2011).
