Lactate production in different fitness levels in exercise execution on extension chair
Abstract
Introduction: Studies analyzing the metabolic effects of overloading on the body of people with different degrees of trainability are needed to understand the physiological mechanisms of adaptation generated by resistance training. Objective: check the blood lactate concentration levels in different levels of muscular fitness in the execution of exercise in the extensor chair. Materials and methods: The sample consisted of 40 individuals (men), aged 21.85±1.9 years, divided into two groups: (1) Beginners and (2) Advanced. The experimental protocol was composed by exercise extension of knees (3 series 09-12 maximal repetitions); Borg scale, and blood lactate concentration. Results: There was no statistically significant difference in blood lactate concentration between the groups; However, the group of beginners presented higher lactate production (10.2±2.67 mmol) when compared to the group of advanced (9.1 ± 2.56 mmol). Regarding the subjective perception of effort, the scores were statistically different (p = 0.01), being 16.6 ± 1.59 points for the group (1) and 15.1±2.07 points for the group (2). Conclusion: It was concluded that there was no significant difference in the blood lactate concentration between the two groups, but the subjective sensation of the effort of the group of beginners was higher even with the exercise with a lower load in the number of series and repetitions proposed in the protocol.
