How Many Meters Is A Marathon

Long-distance running or long-distance running is a form of continuous running of at least 3 km (1.9 mi). Physiologically, it is primarily aerobic in nature and requires endurance as well as mental strength.

Two different types of breathing occur in sustained running. A more notable aspect that runners encounter more often is aerobic respiration. This happens when oxygen is available and the body can use the oxygen to increase energy and muscle activity. Anaerobic respiration, on the other hand, occurs when the body is deprived of oxygen and is common towards the latter part of races, which is an impulse to achieve greater intensity. In general, both types of breathing are used frequently by endurance runners, but they are very different from each other.

Among mammals, humans, especially among primates, are well adapted to run significant distances. Continuous running is also found in nomadic ungulates and a limited number of terrestrial carnivores such as bears, dogs, wolves, and hyenas.

In modern human society, long-distance running has many purposes: people may engage in running for physical exercise, entertainment, as a means of travel, for economic reasons, or for cultural reasons. Long-distance running can also be used as a tool to improve cardiovascular health.

Continuous running is often a component of physical military training. Long-distance running as a form of tradition or ceremony is recognized among the Hopi and Tarahumara peoples, among others.

In the sport of athletics, long-distance events are defined as events covering a distance of 3 km (1.9 mi) or more. The three most common types are track running, road running, and cross-country running, all of which are defined by terrain—all airways, roads, and natural terrain, respectively.

Anthropological observations of modern hunter-gatherer communities have provided accounts of long-distance running as a historical method of hunting among the Kalahari San.

With this method, the hunter would run between an hour and several days at a slow and steady pace, in an area where the animal had no place to hide. A fast running animal is forced to pant to cool itself, but as long as the chase continues, it will not have time to run again, and after a while it will collapse from exhaustion and heat.

With the development of agriculture and culture, long-distance running had more and more purposes besides hunting: religious ceremonies, delivering messages for military and political purposes, and sport.

One of the most famous running heralds is Pheidippides, who ran from Marathon to Mount Athos to announce the Greek victory over the Persians at the Battle of Marathon in 490 BC. He fell and died delivering the message “we won”.

Did Pheidippides run from Marathon to Atsa or between other cities, how long was it, and was he the one who delivered the message of victory?

Typical long-distance track races range from 3,000 meters (1.87 mi) to 10,000 meters (6.2 mi), cross-country races typically cover distances of 5 to 12 km (3 to 71 ⁄2 mi), and road races are much longer. can be Reaches a range of 100 km (62 mi) or more. In collegiate cross country in the United States, women run the 8,000 or 10,000 meters, depending on the division, and the women run the 6,000 meters.

There are four long-distance running events at the Summer Olympics: the 3,000-meter cross-country chase (which also includes steeplechase and diving), 5,000 meters, 10,000 meters, and the marathon (42,195 kilometers or 26 miles, 385 yards).

Humans are among the best distance runners of all running animals: game animals are faster over short distances but less stable than humans.

Unlike other primates, whose bodies are adapted to walk on all fours or climb trees, the human body evolved to walk upright and run about 2-3 million years ago.

One of the differences between vertical walking and running is energy consumption during movement. When walking, people use about half the energy needed to run.

Max is the capacity to take up and consume maximum oxygen during fatiguing exercise. Long-distance runners typically perform at about 75-85% of their peak aerobic capacity, while sprinters typically perform near 100% of their peak.

Aerobic capacity depends on the transport of large amounts of blood to the lungs and from the lungs to all tissues. This, in turn, results from having a high cardiac output, sufficient hemoglobin levels in the blood, and an optimal vascular system for blood distribution.

A 20-fold increase in local blood flow in skeletal muscle is necessary to meet the oxygen demand of the muscles during maximal exercise, which is 50 times greater than at rest for endurance athletes such as marathon runners.

Elite long-distance runners often have a lower resting heart rate, which allows them to achieve larger hearts and greater aerobic capacity. An increased heart size can allow a person to achieve a greater stroke volume. A simultaneous decrease in stroke volume occurs with an initial increase in heart rate at the beginning of exercise. Despite the increased heart size, the aerobic capacity of the marathon runner is limited by this closed and ever decreasing heart rate.

The amount of oxygen that the blood can carry depends on the increased blood volume during the race and the amount of hemoglobin in the blood.

Other physiological factors that affect the aerobic capacity of a marathon runner include lung diffusivity, mitochondrial zyme activity, and capillary density.

A long-distance runner’s running economy is their steady-state oxygen demand at specific speeds and helps explain differences in performance for runners of very similar aerobic capacity. It is often measured in liters or milliliters (L/kg/min or mL/kg/min) of oxygen consumed per kilogram of body weight. since 2016

The physiological basis for this was unclear, but it depended on the accumulation of years of running, reaching a point beyond which longer individual training sessions could not be sustained.

A long-distance runner’s speed at lactate threshold is strongly correlated with their performance. Lactate threshold is essentially the intersection between aerobic energy use and anaerobic energy use and is considered a good indicator of the body’s ability to efficiently process chemical energy and convert it into mechanical energy.

Lactate threshold training involves walking exercise designed to build strength and speed rather than increasing the efficiency of the cardiovascular system at absorbing and transporting oxygen.

By running at lactate threshold, your body will be more efficient at clearing lactic acid and recycling your muscles for fuel. Uncertainty exists regarding how lactate threshold affects endurance performance.

A marathon runner must obtain sufficient glycogen stores to sustain high-intensity running. Glycogen can be found in skeletal muscle and liver. With low levels of glycogen stores at the start of a marathon, premature depletion of those stores can reduce performance or prevent the completion of the race. ATP production by aerobic pathways can be further limited by glycogen depletion.

Free fatty acids act as a protective mechanism for glycogen stores. Artificially raising these fatty acids in combination with endurance training demonstrates a marathoner’s ability to sustain higher endurance for longer periods of time. A long duration of running intensity is associated with a high turnover rate of fatty acids, which allows the athlete to conserve glycogen reserves later in the race.

Maintaining core body temperature is critical to a marathon runner’s performance and health. Failure to reduce the increased body temperature can lead to hyperthermia. To reduce body temperature, metabolically generated heat must be removed from the body through sweating, which in turn requires rehydration to compensate. Fluid replacement is limited but can help keep the body’s core temperature cooler. Due to inefficient gastric emptying, fluid replacement during exercise of this intensity is physiologically difficult. Partial fluid replacement can help prevent overheating of the marathoner’s body, but cannot keep up with fluid loss through sweat evaporation.

The high altitude of these countries is proven to help these runners achieve more. High altitude, combined with endurance training, can cause an increase in red blood cells, which allows for increased oxygen delivery through the arteries. Most of these successful East African runners come from the three mountain districts that stretch along the Great Rift Valley.

While height is a contributing factor, the culture of hard work, teamwork as well as a sophisticated institutional structure also contribute to their success.
