Energy chews are a popular and effective method for refueling during endurance exercise. Unlike gels, their solid, bite-sized form offers better portion control and can alleviate flavor fatigue, making them a preferable choice for many athletes. However, their effectiveness hinges on a properly timed and consistent intake strategy. This guide breaks down how to use them for maximum benefit.
Pre-Workout Fueling: Topping Off Your Stores
While your body's glycogen stores are sufficient for exercise lasting less than 60-90 minutes, it's beneficial to top them off for longer or more intense sessions. Consuming energy chews before a workout ensures your muscles have an immediate fuel source from the start, which can delay fatigue. For optimal pre-workout fueling, follow these guidelines:
- Timing: Eat one serving (typically half a pack or 4-5 chews, but check the product label) approximately 15-30 minutes before your workout or race.
- Hydration: Always consume your chews with a few sips of water. This aids in digestion and ensures the carbohydrates are readily available for your body to use.
- Consider Intensity: For short, high-intensity efforts, a pre-workout serving might be all you need. For longer efforts, this is just the beginning of your fueling plan.
In-Workout Fueling: The During-Activity Strategy
For any activity lasting longer than an hour, consistent refueling is non-negotiable. The goal is to provide a steady supply of carbohydrates to your muscles without overloading your digestive system. The frequency of your intake depends on the duration and intensity of your exercise.
- Moderate Intensity (over 60 minutes): Aim for a steady intake every 45-60 minutes. A typical approach is to consume a full serving of chews per hour, spaced out to prevent spikes.
- Higher Intensity or Longer Events (over 2 hours): Increase your frequency. Many athletes find success with smaller, more frequent doses—about 2-4 chews every 15-30 minutes. The total goal is to hit a target carbohydrate intake per hour, often between 30-90 grams depending on your body and exercise intensity.
Example Intake Plan for a 3-hour Workout
- Start (15 mins before): 1 serving of chews with water.
- Hour 1 (at 45 mins): 1 serving of chews with water.
- Hour 2 (at 90 mins, then 120 mins): 1 serving every 30 minutes, or 2 chews every 15 mins.
- Hour 3 (at 150 mins, then 180 mins): 1 serving every 30 minutes, or 2 chews every 15 mins.
Best Practices for Using Energy Chews
- Test in Training: Never try new fueling strategies on race day. Practice your fueling plan during long training sessions to train your stomach and identify any potential issues.
- Start Early: Begin your fueling regimen before you feel a drop in energy. By the time you feel fatigued, it's often too late to recover quickly.
- Listen to Your Body: While guidelines are helpful, every athlete is different. Your absorption rates, intensity, and hydration levels all play a role. Pay attention to how you feel and adjust your intake accordingly.
- Don't Overdo It: Consuming too many chews too quickly can lead to stomach cramps and other gastrointestinal issues. Stick to your planned intake and avoid the temptation to eat more just because they taste good.
- Combine with Other Fuel: Chews can be part of a larger nutrition plan that includes sports drinks and gels. Just remember to account for your total carbohydrate intake from all sources to avoid over-fueling.
- Carry a Log: Keep a record of your fueling during training. Note what you ate, when, and how it made you feel. This helps you refine your strategy over time.
Comparison: Energy Chews vs. Gels
| Feature | Energy Chews | Energy Gels |
|---|---|---|
| Portion Control | Excellent; can eat one or two at a time. | Limited; typically an all-at-once dose. |
| Texture | Solid, satisfying to chew; can combat flavor fatigue. | Gel-like consistency; some find it less palatable. |
| Absorption Speed | Slightly slower due to chewing; aids controlled intake. | Very fast; absorbs rapidly for quick energy. |
| Consumption Method | Requires chewing, which can be difficult during high intensity. | Easy to consume quickly while running or cycling. |
| Hydration Needs | Requires water to aid digestion and absorption. | Often needs water (except for isotonic gels) to prevent dehydration. |
| Mess Factor | Low; pre-portioned and easy to handle. | Higher risk of mess and sticky residue. |
Conclusion: Finding Your Optimal Strategy
The frequency at which you should take energy chews depends on your workout duration, intensity, and personal tolerance. For any activity over an hour, a consistent intake of 30-90 grams of carbohydrates per hour is recommended, delivered through chews consumed every 15 to 45 minutes. By practicing your fueling strategy during training, staying hydrated, and listening to your body, you can confidently use energy chews to maintain peak performance and achieve your endurance goals.
