Abstract

Background The consumption of isolated soy protein (ISP) is well known for its benefcial efect on muscle recovery. However, the efect of its combination with maltodextrin, honey, or dates has never been investigated. This study sought to determine the best combination of ISP and diferent types of carbohydrates for muscle fatigue recovery in the exercise�induced fatigue rat model. Methods After 3 days of adaptation, 24 9-week-old Sprague Dawley rats were randomly assigned to four groups: the malto�dextrin supplementation (control) group, the maltodextrin and ISP (P1) group, the honey and ISP (P2) group, and the dates and ISP (P3) group. Each group included six rats for the 1-week experiment. Before the experimental period, baseline values of body weight and lactate dehydrogenase (LDH) were recorded for each group. Throughout the study, all rats performed the swimming test until exhaustion every 2 days. Following supplementation, LDH levels were measured three times: immedi�ately after exercise, 3 h later, and 7 days later. Results The results showed that the mean LDH of the P2 group was signifcantly decreased after 3 h (63%) and 7 days (66%) of supplementation (p = 0.05) compared with the other groups. Conclusion Ingestion of ISP combined with honey after exercise improves muscle recovery in rats
