    1. Age-associated loss of skeletal muscle mass and strength can partly be counteracted by resistance training, causing a net synthesis of muscular proteins. Protein synthesis is influenced synergistically by postexercise amino acid supplementation, but the importance of the timing of protein intake remains unresolved.
    2. The study investigated the importance of immediate (P0) or delayed (P2) intake of an oral protein supplement upon muscle hypertrophy and strength over a period of resistance training in elderly males.
    3. Thirteen men (age, 74 ± 1 years; body mass index (BMI), 25 ± 1 kg m-2 (means ± S.E.M.)) completed a 12 week resistance training programme (3 times per week) receiving oral protein in liquid form (10 g protein, 7 g carbohydrate, 3 g fat) immediately after (P0) or 2 h after (P2) each training session. Muscle hypertrophy was evaluated by magnetic resonance imaging (MRI) and from muscle biopsies and muscle strength was determined using dynamic and isokinetic strength measurements. Body composition was determined from dual-energy X-ray absorptiometry (DEXA) and food records were obtained over 4 days. The plasma insulin response to protein supplementation was also determined.
    4. In response to training, the cross-sectional area of m. quadriceps femoris (54.6 &#177; 0.5 to 58.3 &#177; 0.5 cm2) and mean fibre area (4047 &#177; 320 to 5019 &#177; 615 &#181;m2) increased in the P0 group, whereas no significant increase was observed in P2. For P0 both dynamic and isokinetic strength increased, by 46 and 15 %, respectively (P < 0.05), whereas P2 only improved in dynamic strength, by 36 % (P < 0.05). No differences in glucose or insulin response were observed between protein intake at 0 and 2 h postexercise.
    5. We conclude that early intake of an oral protein supplement after resistance training is important for the development of hypertrophy in skeletal muscle of elderly men in response to resistance training.

  2. You should get an award for all the resarch you do for us. I appreciate all your work!

  3. Exerrent. thanks mang.

    Haha thanks man, I go on these A.D.D. research streaks where I thrive on knowledge. Heck I want to be the best athlete I can be as well. This will make me start bringing protein shakes to the gym with me. It is amazing the hypertrophy difference between immediately after and 2 hours after!!!!
