No. 4: Recovering With Both Carbs + Protein
Recovery foods should offer a foundation of carbs with protein as the accompaniment. A reasonable target is about 240 calories of carbs (60 g carb) and about 80 calories (20 g) of protein. Some popular choices include Greek yogurt with honey, chocolate milk, cereal with milk, and pasta with meat sauce. You need not buy engineered recovery foods; standard fare works fine.
Note that recovery foods can be eaten pre-exercise. That is, a pre-exercise yogurt gets digested into amino acids and glucose; those food components will be ready and waiting to be put into use when you stop exercising. In a 10-week study with recreational body builders, those who consumed a protein-carb supplement both immediately before and right after the mid-afternoon strength training session gained 2.3 pounds more muscle and 7 pounds more in strength (as measured by bench press), compared to the group without the pre- and post-exercise fuel. (2)
Athletes who do two workouts a day really need to rapidly refuel with a proper recovery diet. A six-week study with swimmers reports those who did two workouts (morning and afternoon) sprinted slower than those who swam only in the afternoon (3). If nutrition is your missing link, don't even think about double workouts.
Solution: You may not feel hungry for solid foods after a hard bout of exercise, but you are likely thirsty. A fruit smoothie (made with yogurt) is excellent for recovery, as is a chug of chocolate milk. Both contain carbs to refuel, and protein to build and repair muscles and reduce muscle soreness.
No. 5: Rest Days for Muscles to Refuel
Rest is an important part of a training program; muscles need time to refuel and heal. Depleted muscles may need more than 24 hours to replace glycogen stores. Hence, rest days with little or no exercise enhance a training program.
Athletes who want to lose weight commonly hesitate to take a rest day; they fear they will "get fat." These athletes need to understand:
1) On a rest day, they will feel just as hungry because the muscles need food to refuel.
2) They will gain (water) weight. For each 1 oz. of glycogen, the muscles store about 3 oz. water. This water gets released during exercise; it is beneficial.
Solution: Plan one to two rest days a week. Notice how much better you are able to perform the day after a rest day.
No. 6: Adequate FluidsAthletes who stay well hydrated can train harder and perform better. For each one percent of body weight lost via sweat, your heart has to beat three to five more times per minute (4). This creates needless fatigue.
Solution: If you are well-hydrated, you will need to urinate every two to four hours, and your urine will be a light color. If you are sweat heavily, you really should learn how much sweat you lose (and thereby need to replace) during a workout. Do this my weighing yourself naked before and after exercise. For each pound (16 oz.) of sweat, you should drink at least 16 to 24 oz. of fluid.
No. 7: Sodium Before Exercise in the HeatResearch with trained cyclists reports they rode 20 minutes longer to exhaustion (99 vs. 79 minutes) in 90 degrees Farenheit (32 degrees Celsius) heat when they drank a pre-ride beverage with about 1,000 vs. 150 mg sodium. They drank no fluids while riding. (5)
Solution: If you train and compete in the heat, you should consume salty foods beforehand. This holds water in your body and reduces your risk of becoming dehydrated.
No. 8: The Sports Dietitian (RD, CSSD)
Serious athletes generally have a support crew that includes a coach, sports psychologist, medical doctor, physical therapist and massage therapist. But to their detriment, some fail to have a sports dietitian on their team. Don't let that be your case.
Solution: To get the most from your workouts, use the referral network at www.SCANdpg.org to find a local registered dietitian who is a Board Certified Specialist in Sports Dietetics (RD CSSD). This professional can help you:
- resolve your struggles with "no time" to eat properly
- find pre-exercise fuel that reduces stomach problems and "transit trouble"
- attain your desired weight and percent body fat
- transform disordered eating into effective fueling
