    A bowl of Wheaties for your post training meal

    A bowl of Wheaties for your post training meal (*study)
    by Anthony Roberts

    A 2008 review of milk (J Int Soc Sports Nutr. 2008 Oct 2;5:15.) determined that it is an effective post-resistance exercise beverage that positively effects protein metabolism and increases muscle protein synthesis and net muscle protein balance, and when combined with exercise, a post-workout glass of milk can result in elevated gains in muscle hypertrophy. An earlier study (Int J Sport Nutr Exerc Metab. 2006 Feb;16(1):78-91.) revealed that a glass of chocolate milk improved total work and time to exhaustion between repeated exercise bouts better than carb/electrolyte replacement drinks.

    Now, it appears that we can have that milk along with a bowl of cereal (at least according to a study funded by Wheaties):


    Cereal and nonfat milk support muscle recovery following exercise.

    ABSTRACT:

    BACKGROUND: This study compared the effects of ingesting cereal and nonfat milk (Cereal) and a carbohydrate-electrolyte sports drink (Drink) immediately following endurance exercise on muscle glycogen synthesis and the phosphorylation state of proteins controlling protein synthesis: Akt, mTOR, rpS6 and eIF4E.

    METHODS: Trained cyclists or triathletes (8 male: 28.0 +/- 1.6 yrs, 1.8 +/- 0.0 m, 75.4 +/- 3.2 kg, 61.0 +/- 1.6 ml O2*kg-1*min-1; 4 female: 25.3 +/- 1.7 yrs, 1.7 +/- 0.0 m, 66.9 +/- 4.6 kg, 46.4 +/- 1.2 mlO2*kg-1*min-1) completed two randomly-ordered trials serving as their own controls. After 2 hours of cycling at 60-65% VO2MAX, a biopsy from the vastus lateralis was obtained (Post0), then subjects consumed either Drink (78.5 g carbohydrate) or Cereal (77 g carbohydrate, 19.5 g protein and 2.7 g fat). Blood was drawn before and at the end of exercise, and at 15, 30 and 60 minutes after treatment. A second biopsy was taken 60 minutes after supplementation (Post60). Differences within and between treatments were tested using repeated measures ANOVA.

    RESULTS: At Post60, blood glucose was similar between treatments (Drink 6.1 +/- 0.3, Cereal 5.6 +/- 0.2 mmol/L, p < .05), but after Cereal, plasma insulin was significantly higher (Drink 123.1 +/- 11.8, Cereal 191.0 +/- 12.3 pmol/L, p < .05), and plasma lactate significantly lower (Drink 1.4 +/- 0.1, Cereal 1.00 +/- 0.1 mmol/L, p < .05). Except for higher phosphorylation of mTOR after Cereal, glycogen and muscle proteins were not statistically different between treatments. Significant Post0 to Post60 changes occurred in glycogen (Drink 52.4 +/- 7.0 to 58.6 +/- 6.9, Cereal 58.7 +/- 9.6 to 66.0 +/- 10.0 mumol/g, p < .05) and rpS6 (Drink 17.9 +/- 2.5 to 35.2 +/- 4.9, Cereal 18.6 +/- 2.2 to 35.4 +/- 4.4 %Std, p < .05) for each treatment, but only Cereal significantly affected glycogen synthase (Drink 66.6 +/- 6.9 to 64.9 +/- 6.9, Cereal 61.1 +/- 8.0 to 54.2 +/- 7.2%Std, p < .05), Akt (Drink 57.9 +/- 3.2 to 55.7 +/- 3.1, Cereal 53.2 +/- 4.1 to 60.5 +/- 3.7 %Std, p < .05) and mTOR (Drink 28.7 +/- 4.4 to 35.4 +/- 4.5, Cereal 23.0 +/- 3.1 to 42.2 +/- 2.5 %Std, p < .05). eIF4E was unchanged after both treatments.

    CONCLUSION: These results suggest that Cereal is as good as a commercially-available sports drink in initiating post-exercise muscle recovery.

    I'm glad that they aren't just repeating the same post-WO research that's already been done but substituting their own product to show it's "superior". Oh wait...

    No gym for home, work out floor with 30, but is it for 20 like 30 lb when you no lift it to be for men, for 30 lbs instead? or half is 10 for 20 pounds?
