Road cycling is not only a very popular sport in today’s society, but it is also one of the most challenging and demanding sports . This is because there is a number of external factors that can very easily influence the performance of the riders and have a drastic effect on how well they perform on the day of a race or similar event. These external factors can range anywhere from the weather conditions to the quality of bicycle that the athlete is using. Aside from this, there is also a number of other factors that can be taken into consideration, and applied through their training programmes to not only help improve the performance of the athlete in their races, but also to ensure that they remain in top physical health and remain injury free which is crucial for an athlete to be able to perform to the best of their ability. As a cyclist, training almost everyday is ideal for allowing physiological adaptations to occur such as improvement of efficiency of the cardiovascular system. For my client I will be looking at how nutrition and biomechanical principals are relevant to the athlete and how they can have an affect on the cyclist during a cycling race event. For a road cycling athlete there are a number of physiological adaptations that can occur through continuous exercise everyday. This can be seen through the cardiovascular system of the athlete. The cardiovascular system of an athlete can be affected differently depending on the type of exercise it is being used for. In this case the client is constantly undergoing endurance training (aerobic training) and therefore will have a specific effect on the cardiovascular system of the athlete. These physiological adaptations from the training will have an effect on the cardiovascular system, include increase in stroke volume- this is the amount of blood that is pumped per contraction/ amount of blood pumped from the left ventricle per heartbeat. As the athlete undergoes regular exercise the strain that it will put on the heart will cause the stroke volume to increase and the athletes heart will be able to pump more blood from the left ventricle with each heartbeat. According to C.A Vella , R.A Robergs (2005), in a study done to see the effect that exercise has on stroke volume in trained and untrained participants, they found that in trained participants the “ventricular ejection times were longer” and the “ diastolic filling times were shorter”. This shows that

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
