چکیده مقاله :
This review illustrates the impact of carbohydrate (CHO) and protein (PRO) supplementation on cycling performance. Strategic nutritional planning greatly benefits endurance athletes, particularly cyclists, as it underscores the critical role of macronutrient consumption in improving on the track/road performance and recovery. CHO is the primary energy source for prolonged cycling, as they are crucial for preserving optimal performance by preventing glycogen depletion and delaying fatigue. The efficacy of CHO is significantly influenced by their glycemic index (GI). High-GI CHO offers a rapid energy source that facilitates muscle glycogen resynthesis and sustained performance. Research suggests that high-GI CHO can increase muscle glycogen levels by up to 40% within four hours, underscoring their significance during and after pedaling. PRO, although not the primary energy source, is essential for synthesizing and repairing muscles, particularly during prolonged and intensive cycling. Incorporating essential amino acids to facilitate recovery is imperative, as they aid in muscle protein synthesis and mitigate muscle fatigue. Recent studies have demonstrated that PRO supplements, especially after pedaling, significantly enhance muscle glycogen and protein synthesis replenishment, leading to quicker recovery and improved performance during cycling sessions. The synergistic benefits of the combined supplementation of CHO and PRO are greater than those of each macronutrient alone. This combination improves endurance, delays fatigue, and ensures more efficient recovery by increasing glycogen storage, accelerating recovery, and enhancing muscle protein synthesis. The optimization of the benefits of these supplements is contingent upon the timing, dosage, and composition. Glycogen replenishment and muscle protein synthesis are optimized by consuming CHO and PRO immediately prior to and following exercise. This is particularly true for high-GI carbohydrates, such as glucose, and swiftly assimilated PRO, such as whey. In conclusion, this review provides practical recommendations for cyclists seeking to optimize their nutritional strategies by synthesizing findings from various studies. Cyclists can enhance their overall performance and achieve long-term athletic success by developing effective dietary plans that improve endurance, defer fatigue, and facilitate efficient recovery, facilitated by understanding the complex interactions between these macronutrients.
