Intake Of Water-soluble Protein During An Interval Of Repeated Strenuous Exercises Can Improve Serum Myoglobin
Levels

Chiaki Sanbongi1, Seigo Baba1, Hisataka Ambe2, Takeshi Oyama3, Kenichi Suijo4, Yuki Sakamoto2, Katsura Takahara2, Mihoko Ishizaka1, Kunihiko

Many athletes consume protein both immediately after exercise and before sleeping to build up the body and to recover from strenuous exercise. Little is known about the
effects of protein supplementation during exercise because protein can have a bitter taste. Recently, athletes have been consuming a sports drink containing good tasting and
rapidly absorbed water-soluble protein, without evidence of any obvious benefit.
PURPOSE: To determine whether intake of water-soluble protein during exercise has a favorable effect on muscle damage, performance, and soreness.
METHODS: Japanese trained male athletes (n=7) performed two sessions of high intensity cycle ergometer exercise. In each session, subjects did five repetitions of 10 s of maximal
intensity riding interrupted by 50 s of resting. Subjects consumed protein (14.1 g/400 mL) either during exercise or immediately after exercise. Blood lactic acid, serum myoglobin, CK, and
LDH were measured pre- and post-exercise. Perceived muscle soreness and psychological mood change (Profile of Mood State: POMS) were investigated.
RESULTS: Serum myoglobin, CK, and LDH increased significantly 2 h after exercise. Intake of water-soluble protein during exercise (relative to protein intake after exercise)
decreased myoglobin, CK, and LDH. POMS scores (fatigue, total scores) were also improved.
CONCLUSIONS: In contrast to supplementation after exercise, supplementation during exercise attenuated post-exercise muscle damage and fatigue. The results suggest that
ingestion of protein during exercise may be important.

Supplementing Water-soluble Protein Can Improve Repetitive High Intensity Anaerobic Performance With Suppressed
Serum Myoglobin Elevation

Yoshiharu Fujieda1, Taksehi Oyama2, Hisataka Ambe1, Chiaki Sannbongi3, Seigo Baba3, Kenichi Suijo4, Yuki Sakamoto1, Katsura Takahara1, Soutaro

Many studies have revealed the effects of supplementing protein on endurance exercise performances or attenuating muscle damage derived from resistance training, whereas
the evidences of protein supplementation for strenuous intermittent exercise are still insufficient.
PURPOSE: To investigate the effects of a protein beverage on anaerobic performances and muscle damage through double-blind manner.
METHODS: Subjects consisted of 7 Japanese male collegiate athletes (age; 21.4 ± 0.5yrs, height; 176.9 ± 4.8cm, weight; 70.2 ± 5.8kg) underwent twice the same intermittent
anaerobic exercise protocol on the different 2 days under supplementing either water-soluble protein of 14.1g or placebo in crossover research design. Both on the 1st and the 2nd
day, all the participants accomplished repetitive high-intensity sprint exercises composed of 2 sessions, and consumed protein or placebo before and after the 1st session. Each
session included 5 bouts of 10 sec. cycle pedaling with maximal efforts at the workload of 0.075 kp. per body weight and 50 sec. intervals. Measuring serum myoglobin, CK and
LDH was done before and after exercise to evaluate muscle damage.
RESULTS: ANOVA revealed significant differences in both anaerobic powers and changing patterns of serum myoglobin level. In contrast to the condition of taking placebo,
subjects demonstrated not only higher achievement of total power outputs (6856 ± 669 vs.6730 ± 693 watts, p<0.05) but also lower serum myoglobin concentrations at 2-hour
(39.0 ± 10.8 vs.52.0 ± 16.3 ng/ml, p<0.05) and 3-hour (33.8 ± 8.9 vs.44.3 ± 14.3 ng/ml, p<0.05) after exercise under supplementing protein.
CONCLUSIONS: Supplementing water-soluble protein can improve repetitive highly-demanding anaerobic performance with suppressed serum myoglobin elevation.

si l'on prend de la whey pendant l'entrainement, on ne prend plus de bicarbonate je suppose ? histoire d'éviter de roter sa whey

A choisir entre les glucides et la whey pendant l'entrainement, que prend finalement ?

Ca ferait de la whey avant, pendant,après :o

Je n'arrive pas à saisir l'intêret de bicarbonate...
Tu en parles dans quel bouquin? Interessant uniquement lors d'une grosse baisse des glucides? pour pas avoir un organisme trop acidifié?

j'en parle dans les 3 livres sur les suppléments
c'est bon pour augmenter la performance, prendre du muscle, perdre du gras et ralentir le vieillissement
