Training intensity distribution (TID) is an essential tool to prescribe the training stimulus, which depends on the volume and intensity of a single training session but also on a longer-lasting period of training. These two signaling pathways show, for example, how different types of endurance training may cause similar adaptive responses. This implies that high mitochondrial oxidative capacity, improved fat oxidation, and increased glucose transport capacity in the skeletal muscle of endurance athletes can be achieved either by high training volumes, high intensities, or various combinations of both. Both factors have similar subsequent targets in the skeletal muscle that support the development of the aerobic muscle phenotype. The second factor is the relationship between high-intensity exercise and a reduction in ATP concentration in the muscle, leading to a relatively large simultaneous increase in adenosine monophosphate (AMP) that activates the AMP-activated protein kinase (AMPK). A sustained increase in intramuscular calcium, occurring during prolonged endurance training or high training volumes, activates the calcium calmodulin kinases as a mitochondrial biogenesis messenger. Two of these primary factors are increases in calcium concentration and changes in energy status in the muscle. As evaluated by Coffey and Hawley, there seem to be at least four primary factors that can increase mitochondrial mass and glucose transport capacity in skeletal muscle after various types of exercise training. XCO athletes and other endurance athletes use a variety of strategies to enhance performance, as different training principles related to exercise intensity and volume are known to improve the energy status of the working muscle, resulting in an increased ability to maintain higher muscle power output over time. The alternating intensive loads are thereby far above the limit of aerobic endurance performance and thus lead to a rapid reduction in glycogen and an exponential increase in lactate concentration, which inhibits aerobic fat metabolism even in phases of low intensity. The physiological characteristics of XCO athletes indicate that aerobic capacity and the ability to maintain high work rates over a long period are important requirements for competing at a high level. Former studies show that XCO races are performed at an average heart rate close to 90% of the maximum, or 84% of maximum oxygen uptake (VO 2max), and more than 80% of race time is spent above the lactate threshold. Elite athletes have to finish 4–7 laps on undulating circuits with technical descents, forest roads, rocky paths and obstacles, which are 4–6 km long, leading to race durations from 80 up to 100 min. However, due to their large number of alternating climbs and descents, XCO races are regarded as high-intensive intermittent activities. Mountain bike cross-country Olympic (XCO) races are denoted as endurance competitions. Despite the lack of significant superiority in this and some other studies, many athletes and coaches prefer POL because it produces at least equivalent effects and requires less training time. 2.6%), but not for maximal efforts lasting 10 to 300 s. 2.3%), and for maximal aerobic performance (4.4% vs. 2.8%) and individual anaerobic lactate threshold (5.1% vs. However, a small tendency toward better effects for POL was seen for cycling power output during the race (4.4% vs. The results did not show statistically significant differences between POL and LIT, as both interventions led to slight improvements. The superiority of one of the two methods could not be shown in this study.

This randomized controlled trial compared the effects of a polarized training model (POL) to a low-intensity training model (LIT) on physiological parameters and mountain bike cross-country Olympic (XCO) race performance in eighteen competitive XCO athletes (17.9 ± 3.6 years). To improve performance in endurance sports, it is important to include both high-intensity and low-intensity training, but there is neither a universally accepted practice nor clear scientific evidence that allows reliable statements about the predominance of a specific training method.
