This summer, getting outside for physical activity is more important than ever. Fresh air and exercise contribute toward a stronger immune system, better mood, and fitter body.1 Exercise may also help improve circulation, blood sugars, and cholesterol levels.2 We interviewed two registered dietitian nutritionists (RDNs) with experience in sports nutrition to share their best summer workout foods.
Best Sources of Pre-Workout Energy
People get energy from three food sources: carbohydrates, protein, and fats. We asked Germaine Guy, MS, RDN, CSR, LDN:
Which is the best source of energy before starting physical activity?
“Carbohydrates are our body’s preferred energy source and are used to fuel our muscles and brain during exercise. If the diet is lacking carbohydrates, both performance and recovery will be impaired.”
To put this into practice, Nijya Saffo, MS, RDN, LD recommends eating a small meal that includes healthful carbohydrates and even a small amount of lean protein. “You want something that’s going to keep you full, provide energy, but doesn’t have you over-stuffed.”
Nijya’s Pre-Workout Food Pick:
- Peanut butter sandwich on whole grain bread paired with a small bowl of strawberries
The average person who works out for about an hour does not need to replace lost calories with sugar-sweetened beverages like chocolate milk or sports drinks the way competitive athletes do. For the majority of people trying to lose weight, these types of drinks add back the calories just burned.
However, Germaine explained that water and carbohydrates are important to consume within 30 minutes after a workout to restore muscle glycogen, fluids, and salts lost through sweat. If your post-meal snack has very little carbs, you can add a lean protein.
Germaine’s Post-Workout Food Picks:
- fresh fruit (like strawberries)
- PBJ sandwich
- mixed nuts
- Greek yogurt
Staying Hydrated During Summer Activities
Spending more time outside is natural during the summer. However, outdoor physical activity in the heat causes more respiration, more sweating, and a loss of water and electrolytes. Staying hydrated during summer activities is important. Nijya weighs in on whether eight glasses of water are enough to stay hydrated.
“This suggestion has increased to about 11 glasses for women and 12 glasses for men (8 oz. glasses). Hydration needs vary depending on age, gender, health status, and activity level. I tell my clients to check their urine color to determine if they are hydrating enough.”
Nijya’s Hydration Check:
- Clear/light yellow urine= hydrated
- Dark yellow/amber= increase hydration
Children & Teens
Germaine offered general advice for children and teens: “It’s important that they have access and are encouraged to drink water before, during, and after exercise.”
Strawberries are 90% water and are hydrating snacks for kids after playing outside in the heat.
Strawberries for Sports Performance
We asked the sports dietitians to consider whether strawberries would fit into a meal-plan for the recreational athlete. They both agreed strawberries would be a great addition to snacks and meals.
Germaine described strawberries as “a great source of carbohydrates that will help with both fueling muscle glycogen stores pre-exercise and replenishing them afterwards. Strawberries…will not only enhance physical activity, but also your overall health.”
Nijya added, ”Strawberries are low in calories, provide water for hydration, an excellent source of vitamin C, and a good source of fiber. Strawberries are also rich in antioxidants/flavonoids which help reduce inflammation and improve recovery.”
