Abstract
Introduction: Strength is considered a critical parameter for health and physical performance, and there are various meth- odologies for its development. However, to date, protocols associated with the anaerobic threshold and its acute effects have not been described. Objectives: The study aims to determine the acute effects of a strength program consisting of performing four exercises for 8 weeks at the anaerobic threshold level on cardiorespiratory fitness, muscular strength, and energy metabolism. Materials and Meth- ods: Fifteen participants, with an average age of 35.5±4 years, height of 1.78±0.09 meters, and weight of 72.1±12.9 kg, were selected through probabilistic sampling. Three evaluations were conducted, including Vo2max, anthropometry, and a strength test to the an- aerobic threshold in four exercises, with lactate sampling at each attempt. The load associated with the anaerobic threshold was used as specific intensity to implement a three-day training program for eight weeks. Results: The results indicate that the training program at the anaerobic threshold not only improves muscular strength but also has a positive impact on cardiovascular health, body composi- tion, and metabolic markers, supporting its effectiveness as a comprehensive strategy to improve health and physical performance. Conclusions: This study highlights the effectiveness of the 8-week training program based on the anaerobic threshold in improving the overall health and physical performance of participants.
