What are the physiological demands of marathon running?
National level marathon running demands a high aerobic capacity and the ability to perform at a high fraction of it for a sustained period of time. A complex interplay of cardiovascular, musculoskeletal, pulmonary, and metabolic systems is necessary to achieve this.
What is the pace of a marathon runner?
What is the average pace for marathon runners? According to the RunRepeat data, the average pace for a male marathon runner is 6.43 minutes per kilometre, which works out as 10.34 minutes per mile. The average pace for a female runner over 26.2 miles is 7.26 minutes per kilometre, or an 11.55 minute mile.
How do marathon runners sustain or maintain life in relation to life process?
To sustain high intensity running, a marathon runner must obtain sufficient glycogen stores. Glycogen can be found in the skeletal muscles or liver. With low levels of glycogen stores at the onset of the marathon, premature depletion of these stores can reduce performance or even prevent completion of the race.
What happens to your body when you run a marathon?
With a marathon, your body temperature rises throughout the duration of the run such that by the end of the race the body’s core temperature will have risen from the normal level of about 98.6ºF to temperatures as high as 102–103ºF (similar to the temperature you might have with the flu or other illness).
What are the physiological demands of prolonged exercise?
During physical exercise, requirements for oxygen and substrate in skeletal muscle are increased, as are the removal of metabolites and carbon dioxide. Chemical, mechanical and thermal stimuli affect alterations in metabolic, cardiovascular and ventilatory function in order to meet these increased demands.
What is a physiological demand?
A myriad of factors influences the demands of a player, such as the player’s physical capacity, technical qualities, playing position, tactical role and style of playing, as well as ball possession of the team, quality of the opponent, importance of the game, seasonal period, playing surface and environmental factors.
What motivates long distance running?
The challenge of running a marathon is highly stimulating for many runners, providing them with an opportunity to test their physical and psychological abilities. Their feelings of deep personal awareness and positive self-perception might also be motivating (Jordalen and Lemyre, 2015).
How much ATP is needed to run a marathon?
During a race the marathon runner uses approximately 75 kilograms of ATP, and as this amount cannot be stored in the body ATP is resynthesized from different fuels (i.e. PCr, carbohydrates, lipids and protein), with the catabolism of the fuels providing the energy required.
Does running a marathon damage your heart?
Results: Marathon running is associated with a transient and low risk of sudden cardiac death. This risk appears to be even lower in women and is independent of marathon experience or the presence of previously reported symptoms. Most deaths are due to underlying coronary artery disease.
What increases during exercise?
While exercising, the muscles need additional energy as: the breathing rate and volume of each breath increases to bring more oxygen into the body and remove the carbon dioxide produced. the heart rate increases, to supply the muscles with extra oxygen and remove the carbon dioxide produced.
What are the physiological demands of running at 2 hour marathon pace?
NEW & NOTEWORTHY We report the physiological characteristics and O 2 cost of running overground at ∼21.1 km/h in a cohort of the world’s best male distance runners. We provide new information on the absolute and relative O 2 uptake required to run at 2-h marathon pace.
How is the performance of a marathon runner influenced?
Performance in marathon running is influenced by a variety of factors, most of which are of a physiological nature. Accordingly, the marathon runner must rely to a large extent on a high aerobic capacity.
How does oxygen uptake affect a marathon runner?
But great variations in maximal oxygen uptake (VO2 max) have been observed among runners with a similar performance capacity, indicating complementary factors are of importance for performance.
How much O 2 do you need to run a 2 hour marathon?
Using the value for O 2 cost measured in this study, a sub 2-h marathon would require a 59 kg runner to sustain a V̇O 2 of approximately 4.0 L/min or 67 mL/kg/min. NEW & NOTEWORTHY We report the physiological characteristics and O 2 cost of running overground at ∼21.1 km/h in a cohort of the world’s best male distance runners.
