THE IMPORTANCE OF MUSCULAR ENDURANCE IN PHYSICAL PERFORMANCE AND HEALTH PROMOTION: PHYSIOLOGICAL MECHANISMS AND TRAINING STRATEGIES

Many studies talk about muscular endurance which is an essential component of physical performance and overall health. This ability is characterized by the level that the muscles have to exert strength over an extended period without showing fatigue (American College of Sports Medicine [ACSM], 2021). It is influenced by several physiological factors, including the type of muscle fibers, energy systems, and other aspects of muscle fatigue (Enoka & Duchateau, 2020; Zajac, 2021). Type I muscle fibers, which are characterized as resistance muscle fibers or otherwise known as red fibers, are better suited for activities that require long-term endurance (Bassett et al., 2020). Training methods are numerous, one of which is, low-load weight training and high repetitions, isometric and isotonic training, as well as high-intensity interweave method (HIIT) training (Ratamess et al., 2021; Laursen & Buchheit, 2019). Methodology, N=32 people aged 20-29 participated from where we have 18 girls and 15 boys. Everyone participated in the exercise tests, Curl-Up Test, Push-Up Test, Squat Endurance Test. During the testing, the group was asked to maximally respect the execution technique according to the established protocol. The curl-up results difference is significant (p < 0.05). The push-up difference is very significant (p < 0.01). Squat endurance difference is significant (p < 0.05). In conclusion, muscular endurance is an important field of study in sports and medical sciences. Future advances in research on physiological adaptations and personalized training methods will help optimize it for different populations.
