Background: The consumption of isolated soy protein (ISP) is well known for its beneficial effect on muscle recovery. However, the effect of its combination with maltodextrin, honey, or dates has never been investigated. This study sought to determine the best combination of ISP and different 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 maltodextrin 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: immediately after exercise, 3 h later, and 7 days later. Results: The results showed that the mean LDH of the P2 group was significantly 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. © 2023, The Author(s), under exclusive licence to Springer-Verlag Italia S.r.l., part of Springer Nature.
