Fundamentals of Endurance: Aerobic and Anaerobic Training
Aerobic and anaerobic capacities are fundamental in sports. Both are responsible for providing the energy required for muscle movement, although their relative contribution varies depending on the discipline (Chaabene et al., 2017). A well-developed aerobic capacity allows athletes to recover more quickly between intense phases, maintain technical precision even when fatigued, and prevent performance drops (Kamandulis et al., 2018). Although the aerobic system is not primarily responsible for explosive movements, it forms the foundation for repeated peak performance by ensuring efficient recovery.
In contrast, the anaerobic system supplies energy for short, high-intensity actions such as weightlifting, jumps, or strikes (Slimani et al., 2017; Franchini, 2020; Aydin, 2022). Both the alactic component for very short, maximal efforts and the lactic component for intense efforts lasting up to about a minute are relevant here. Developing both energy systems simultaneously is considered crucial in sports like combat sports to maximize overall performance.
Aerobic training typically involves longer-duration, moderate-intensity exercises that engage the cardiovascular system and muscles evenly, improving endurance performance (Chaabene et al., 2017). Modern methods, such as high-intensity interval training (HIIT), can also promote aerobic adaptations, for example, by improving the removal of metabolic byproducts. Anaerobic training, on the other hand, focuses on short, very intense efforts to increase the body’s ability to generate energy without oxygen. This is crucial for explosive movements. In combat sports, which require repeated sequences of longer activity and short high-intensity bursts, both training forms complement each other optimally (Franchini, 2020).
Physiologically, aerobic and anaerobic training elicit different adaptations. Aerobic training increases maximal oxygen uptake (VO₂max), cardiac output, capillary density, and the number and efficiency of mitochondria. Anaerobic training primarily improves muscle strength, power, and muscle mass through increased recruitment of motor units and muscle fiber hypertrophy. Additionally, strength-oriented high-load training enhances bone density and the resilience of tendons and ligaments.
Biochemically, aerobic metabolism uses oxygen to convert carbohydrates and fats into adenosine triphosphate (ATP) via glycolysis, the citric acid cycle, and oxidative phosphorylation. This process is highly efficient, producing up to 30–39 ATP per glucose molecule and providing energy for prolonged, moderate-intensity activity. Byproducts such as carbon dioxide and water are easily eliminated. Anaerobic metabolism, in contrast, operates without oxygen and produces energy much faster but less efficiently: a single glucose molecule yields only about 2–3 ATP. It allows maximal performance for short durations but leads to lactate accumulation and rapid fatigue. In practice, both energy systems operate in parallel, with their contribution shifting according to intensity.
The benefits of combined training are supported by several studies. Schroeder et al. (2019) demonstrated that an eight-week program consisting of 30 minutes of endurance and resistance training three days per week not only reduced diastolic blood pressure by 4 mmHg but also significantly increased upper- and lower-body strength and fat-free mass by 0.8 kg. In people with type 2 diabetes, aerobic training improved HbA1c levels, blood lipids, and cholesterol, especially when combined with resistance training (Sigal et al., 2018).
Clear benefits are also seen in other populations: Kulkarni et al. (2022) reported that structured group endurance training improved muscle strength, balance, and quality of life in older adults, while reducing fear of falling. During pregnancy, regular moderate aerobic exercise can strengthen the cardiovascular system, alleviate discomfort, and increase resilience for childbirth (Hinman et al., 2015).
These findings underline that a periodized training program that targets both aerobic and anaerobic stimuli provides significant advantages not only in competitive sports but also in prevention, rehabilitation, and health-focused exercise.
