Blood lactate and delayed onset muscle soreness responses after two distinct strength training methods
Abstract
Introduction: Strength training has been recommended due to the numerous benefits related to aesthetics, health and fitness. Objective: To analyze the responses of blood lactate and delayed onset muscle soreness after two strength training methods. Methods: Eleven men, 30.0 ± 8.81 years, were subjected to randomized and halftone form of 96 hours, the decreasing pyramid method (4 set 10,12,14 and 16MR and 60-second interval) and forced reps (4 set: 6MR, and interval of 90 seconds) for the exercise bench press, incline bench press and crucifix. To measure the impact of each method the blood lactate and delayed onset muscle soreness were measured before and after each intervention. Results: The method descending pyramid generated higher (p <0.05) blood lactate concentrations (before 1.21 ± 0.65 and 8.42 ± 1.81 mmol / l after) compared to the method of forced repetitions (before 1.28 ± 0.62 and 6.30 ± 1.87 mmol after) and delayed onset muscle soreness did not differ between them. Conclusion: The investigated strength training methods promote important changes in blood lactate concentrations, especially the protocol (descending pyramid) with features of metabolic overload. Therefore, these methods can be a valuable alternative when it aims to switch the type of overload (mechanical and metabolic) of the training session and thus should be chosen prudently and by the needs and goals of the training.
