A banana eaten on the walk from last period to the bus. Team pasta night before the conference semifinal. A cooler of bagels, fruit and chocolate milk under a tent at the Thanksgiving festival. Field hockey players sprint, stop and work bent over for an hour, often in late-summer heat, and many of them are teenagers who are still growing. Field hockey nutrition is mostly about eating enough of the right food at the right times and drinking enough on hot turf. Supplements come last, and only the tested kind. This page covers both, based on sports-nutrition position statements and research.

General information, not medical or dietary advice. Players with medical conditions, food allergies or special diets, and anyone under 18 thinking about supplements, should talk to a doctor or a registered sports dietitian. For the overview of the sport, see our field hockey hub.

Daily eating: energy first

The main guide is the joint position statement on nutrition and athletic performance from the American College of Sports Medicine (ACSM), the Academy of Nutrition and Dietetics and Dietitians of Canada. For supplements, we follow the International Olympic Committee’s (IOC) consensus statement, the NCAA’s banned-substances list and the American Academy of Pediatrics (AAP).

• Carbohydrate is the fuel for sprints. A review of in-season nutrition for basketball, another sprint-and-recover team sport, suggests about 5–7 g of carbohydrate per kg of body weight per day in season. Rice, pasta, potatoes, bread, oats, fruit and milk are the easy sources.
• Protein for repair: ACSM puts athletes’ needs at about 1.2–2.0 g per kg a day, spread across meals and snacks. For a 60 kg (132 lb) player, that’s roughly 72–120 g a day.
• Calcium, vitamin D and bones: a 2024 systematic review found field hockey players had better bone density than sedentary people, which is good news, but bones still need dairy or fortified alternatives, leafy greens and enough total food.
• Color: fruit, vegetables and some healthy fats round it out.

Eating enough: the issue nobody talks about

Back-to-back days of school, practice and games make it easy to under-eat without noticing. When an athlete doesn’t eat enough for the energy they burn, it’s called low energy availability, and over time it can affect bones, hormones, health and performance. The IOC calls this Relative Energy Deficiency in Sport (REDs) and updated its consensus on it in 2023. Signs worth raising with a doctor or sports dietitian include missed or irregular periods, frequent injuries or stress fractures, constant fatigue and weight loss that wasn’t planned. Pack snacks for the gap between school and practice, and don’t skip breakfast before Saturday-morning games.

Hydration on hot turf

Field hockey’s fall season starts in August, mostly on synthetic turf that gets far hotter than grass. During matches in the heat, players in Australia’s national women’s squad sweated 1.2 to 1.8 liters an hour, and 31% of their morning urine tests (specific gravity 1.020 or higher) suggested they were starting the day under-hydrated. Sweat sodium also varied: after a summer of training, the squad’s average sweat sodium was 19% lower than after winter. The takeaways:

• Start hydrated: ACSM suggests about 5–10 mL per kg in the 2–4 hours before exercise, aiming for pale yellow urine.
• Keep losses under 2% of body weight without drinking so much that you gain weight, per the National Athletic Trainers’ Association (NATA).
• Salty sweaters may benefit from extra sodium, which is where electrolyte drinks fit.
• Needs are individual: the researchers saw big differences between players, so weigh yourself before and after a hot practice to learn your own sweat rate.

Before, during and after games

• Before: a carbohydrate-based meal 1–4 hours before (1–4 g per kg, per ACSM), low in fat and fiber close to game time.
• During: about 30–60 g of carbohydrate per hour for stop-and-start sport lasting 1–2.5 hours: a sports drink, orange slices or a few chews at quarter breaks and halftime.
• After: carbs plus about 15–25 g of protein in the first couple of hours, and 125–150% of the fluid you lost.
• Tournament days: when the next game is less than 8 hours away, ACSM suggests about 1.0–1.2 g of carbohydrate per kg per hour for the first 4 hours. In practice: something small and familiar every hour or so.

The full plan, including heat and lightning, is on our field hockey game day page, and post-game habits are on field hockey recovery.

Young players: food first, no shortcuts

• The AAP says sports drinks are for prolonged, vigorous activity, and that energy drinks, which contain stimulants, have no place in children’s and teens’ diets.
• The AAP advises against creatine and other performance-enhancing substances for athletes under 18.
• Teen athletes get what they need from regular meals, snacks and water. A sports dietitian can help a player who is struggling to eat enough.

Supplements for field hockey players: what the evidence says

The IOC consensus statement says a few supplements have good evidence for performance in some situations, many don’t, and all carry a risk of contamination. For field hockey:

• Electrolytes and sports drinks: useful for hot preseason days, tournaments and heavy sweaters.
• Protein powder: a convenient way to get protein after late practices when food isn’t handy. Not better than food.
• Creatine (adults only): one of the most studied supplements, used by many athletes for strength and repeated-sprint training. A UEFA expert group notes it often adds 1–2 kg of body weight. The AAP doesn’t advise it under 18.
• Multivitamin: can help players with a limited diet. Iron supplements should only be taken after a blood test; the UEFA group warns that unneeded iron can do more harm than good.
• Caffeine: a small lab study of 13 male field hockey players found caffeine helped dribbling and ball-handling skills after hard exercise. But caffeine isn’t for everyone (sensitivity, heart conditions, pregnancy, teens), pre-workouts often contain several stimulants, and some stimulants are banned by the NCAA. Check with a doctor first.

Third-party testing and the NCAA banned list

The NCAA’s 2026–27 banned-substances list says there are no NCAA-approved supplements, that supplements “may be contaminated with banned substances not listed on the label,” and that all supplements are taken at the athlete’s own risk. College players should check every product with their athletics staff first. Programs such as NSF Certified for Sport and Informed Sport/Informed Choice test products for banned substances; the NCAA says third-party tested products may be options but can’t remove all risk, and these programs don’t test whether a product works.

Talk to a professional. Before starting any supplement, check with your doctor or a registered sports dietitian, especially for players under 18 and anyone who is pregnant, takes medication or has a heart, kidney or other medical condition. College athletes should also check with their athletics department. Electrolyte products contain sodium; ask your doctor first if you have high blood pressure or follow a low-sodium diet.

Field hockey nutrition: FAQs

What should a field hockey player eat before a game?

A carbohydrate-based meal 3–4 hours before, like pasta, rice, potatoes or a sandwich with lean protein, or a smaller snack 1–2 hours before for early games. Keep fat and fiber low close to game time.

How much water does a field hockey player need?

It varies a lot. Elite players have sweated 1.2–1.8 liters an hour in hot matches. Start hydrated, drink at every break, keep weight loss under about 2%, and weigh yourself before and after a hot practice to learn your own needs.

What should you eat at a field hockey tournament?

Small, familiar, carb-rich food after each game and every hour or so between games: bagels, sandwiches, bananas, pretzels, yogurt, chocolate milk and sports drinks, with water and some salt.

Can NCAA field hockey players take supplements?

There are no NCAA-approved supplements, and any supplement may contain banned substances not on the label. Check every product with your athletics staff, and if you use one, choose third-party tested products, knowing that doesn’t remove all risk.

Is creatine OK for high school field hockey players?

The American Academy of Pediatrics advises against creatine and other performance-enhancing substances for athletes under 18. Teens get more from eating enough, sleeping well and training consistently.
