Effect of proposed exercises to develop lactic endurance on some physiological and biochemical variables of 800-meter runners

Abstract

This study examines the effect of proposed exercises for developing lactic endurance on certain physiological and biochemical variables in 800-meter runners, given the importance of this type of endurance in middle-distance events that rely heavily on the anaerobic lactic energy system. The study aims to identify the impact of the proposed training program on improving the efficiency of vital and functional systems related to performance.

The researcher designed a training program that included exercises specifically aimed at developing lactic endurance. The program was applied to a sample of 800-meter runners over a specified period with regular training sessions. Several physiological variables were measured, such as heart rate and maximal oxygen consumption (VO2 max), in addition to biochemical variables such as blood lactate concentration, both before and after the implementation of the program.

The results showed significant differences in favor of the post-tests, as the proposed exercises contributed to improving physiological efficiency and reducing lactate accumulation, which positively affected endurance capacity and the runners’ performance.

The study concludes that lactic endurance training is an effective method for developing the physical and physiological capacities of 800-meter runners, and it recommends incorporating such exercises into training programs to achieve optimal competitive performance.
