Physical performance and regeneration after exercise is enhanced by the ingestion of
proteins and
carbohydrates. These nutrients are generally consumed by athletes via
whey protein and
glucose-based shakes. In this study, effects of
protein and
carbohydrate on skeletal muscle regeneration, given either by shake or by a meal, were compared. 35 subjects performed
a 10 km run. After exercise, they ingested nothing (control), a
protein/
glucose shake (shake) or a combination of white bread and sour milk cheese (food) in a randomized cross over design. Serum
glucose (n = 35), serum
insulin (n = 35), serum
creatine kinase (n = 15) and
myoglobin (n = 15), hematologic parameters,
cortisol (n = 35),
inflammation markers (n = 27) and leg strength (n = 15) as a functional marker were measured. Insulin secretion was significantly stimulated by shake and food. In contrast, only shake resulted in an increase of
blood glucose. Food resulted in a decrease of pro, and stimulation of anti-inflammatory
serum markers. The exercise induced skeletal muscle damage, indicated by serum
creatine kinase and
myoglobin, and exercise induced loss of leg strength was decreased by shake and food. Our data indicate that uptake of
protein and
carbohydrate by shake or food reduces exercise induced skeletal muscle damage and has pro-regenerative effects.
