Efeitos da suplementação de proteína do soro do leite aliado com massagem terapêutica nos marcadores de danos musculares em indivíduos submetidos a programas de condicionamento extremo

Abstract

The muscle damage caused by physical exercise depends on variables such as time of exercise, load used, volume, intensity, time of rest, among others. Extreme conditioning programs induce great damage to the muscle, thus, several physiotherapeutic and nutritional methods are used to enhance the recovery of the damage caused to the muscle. Whey protein has a characteristic of high biological value, essential and branched-chain amino acids, rapid digestibility and absorption, and is an excellent way to stimulate muscle protein synthesis. Massage, on the other hand, is a traditional method used for muscle recovery by increasing local blood flow, eliminating metabolites, inducing local analgesia, thus increasing muscle recovery kinetics. The aim of this research was to analyze the effect of whey protein supplementation combined with therapeutic massage on muscle damage markers in individuals submitted to extreme conditioning programs. Practitioners of extreme conditioning programs (N = 10) were selected and assigned in two moments, being moment 1, after a competition and moment 2, after another competition. After moment 1, athletes received only nutritional intervention, after moment 2, athletes received nutritional intervention plus physical therapy. During the recovery period, markers of CK and LDH were measured to monitor their recovery, being monitored in 4 moments: baseline, 24, 48, 72 hours after competition. Both groups showed an increase in serum CK levels in relation to baseline. The moment 2 group showed a better recovery rate in 48 hours, confirming that by combining both interventions it is possible to enhance muscle recovery.
