[No.half dozen The decathlon and heptathlon] What is the decathlon and the heptathlon?
Athletes compete in a combination of running, jumping, and throwing events for 2 days
The decathlon (men) and heptathlon (women) are sporting events fought with a combination of running, jumping, and throwing events. The winners are crowned with the titles of the Male monarch of Athletes and the Queen of Athletes, respectively.
These sports accept their roots in the pentathlon held in the ancient Greek Olympics, which consisted of the long jump, discus throw, stadion run, javelin throw and wrestling. The word stadion in Greek means a straight alley of about 200m, and is the root of the word "stadium" in English. The suffix -athlon, as in decathlon and heptathlon, comes from the Greek discussion for "competition," and some English words similar athlete and athletics are too related to the give-and-take.
In the decathlon and heptathlon, the following events are competed in over two sequent days. The sports crave athletes to perform running, jumping, and throwing events one after another, as well as managing their time for warming up and practicing before the competition, then cooling downwardly and taking breaks between events, for which excellent physical competence and perseverance are vital prerequisites, every bit is mental toughness. For this reason, they are known as the hardest of all track and field sports. Of form, regular training is necessary for all of the events.
Their records (fourth dimension and altitude) are converted into points by designated conversion formulas, with the full score determining the ranking lodge.
The formulas are very complex, take for case the 100m sprint. It is calculated every bit score = 4347 x (18-T)one.81 [points], where T is the recorded time (second). This tin be calculated using a scientific figurer, today apps for PCs and smartphones are available which calculate scores simply past inbound the recorded times or distances. Here are the world's top 10 decathlon records.
The electric current globe record in the decathlon is 9126 points, achieved by Kevin Mayer in 2018. The previous globe record was held by Ashton Eaton from IAAF World Athletics Championships Beijing 2015, where the new world record of 9045 points was achieved for the first time in 14 years. Mayer easily broke this record with his astonishing points score, exceeding it by nearly 100 points.
While Mayer'south records in the brusque and centre-distance runs savage short of those of Eaton'southward, his skillful results in the throwing events (shot put, discus and javelin throws), which he is strong in, considerably contributed to his overall score, allowing him to constitute a new world record.
Accept a look at the comparisons between his results (times and distances) from the championship and earth records in each issue. Although Mayer is good in the throwing events, the results were not fifty-fifty close to the globe records of individual events. As he is still a immature athlete, born in 1992, Mayer draws the world's attention for his potential to further progress in the throwing events, and improve on his world record in the future.
The world tape in the heptathlon remains unbroken for over 30 years
Here are the women's top ten heptathlon records. In this sport the current world record is held by Jackie Joyner-Kersee, with 7291 points, which she achieved in 1988. The 2nd best score is 7032 points by Carolina Klüft in 2007, lagging behind the globe'south top by a staggering 259 points, which creates intrigue as to who is going to suspension this outstanding earth tape.
A stadium offers a unique experience of spectating at track and field events at 1 time
The decathlon and heptathlon both take place over two consecutive days in the same stadium. A stadium offers the unique experience of watching the track and field events simultaneously among other enthused spectators. Here is a simple illustration of an athletics stadium. Official stadiums where international and other important competitions take place are equipped with several areas for jumping and throwing events, allowing the competition areas to change co-ordinate to the direction of the air current.
The longest distance throwing upshot is the javelin, which uses the entire length of the turfed field for throwing. The world record for a javelin throw is 98.48m held by Jan Železný (1996). You may think that it is but a question of time earlier we encounter the 100m mark broken, but in fact it was already accomplished in 1984, when the world's kickoff over a 100 meters tape was achieved (104.8m). However, it was felt that the turfed area would be besides short if the record continued to grow over 100 meters, and so the rules were changed to shift the center of gravity of the javelin toward its front so that the flying distance would be shortened by about ten%. Today, the official world records for men and women are the ones achieved later on 1986 and 1999 respectively.
The last event of the decathlon and heptathlon is the heart distance run (men's 1500m and women's 800m), which is extremely hard for athletes physically besides every bit mentally, because the title of existence the king or queen of athletes will be snatched away by others if they fail to shell competitors in the total score, even if they cantankerous the finish line before everyone else. It is heady to see in this race how athletes play out their strategies confronting rivals and squeeze out their remaining strength in their final spurt.
TDK'southward sensors and sensing engineering, supporting sports science and athletes' healthcare
Growing efforts are being fabricated to leverage sensors and sensing applied science to better sports such every bit rail and field events efficiently and finer. For example, movement sensors (acceleration sensors and athwart velocity sensors) are employed to analyze athletes' bodily movements and postures while biosensors mensurate their heartbeat, breathing, body temperature, perspiration and so on, so equally to monitor their physical condition. Environmental sensors serve every bit a means of finding the correlation between performance and the environment by measuring the ambient temperature, humidity, and atmospheric force per unit area. The data tin can and then be analyzed using artificial intelligence (AI) to explore further improvements in rail and field events, too as other sports.
Sensors and sensing technology are also used in devices such as active mass meters that record athletes' daily preparation sessions.
TDK offers a wearable biosensor, the Silmee™ series, for collecting and managing vital information, such as the amount of exercise and pulse rate, past combining loftier-precision sensors and proprietary software and algorithms.
Silmee™ W22 is a wristband type active mass meter, equipped with an acceleration sensor, pulse sensor, temperature sensor, microphone, and an ultraviolet (UV) sensor. Information technology can measure and tape steps made while running or walking, the calories consumed during exercise, likewise as the hours comatose, pulse charge per unit, peel temperature, and the amount of UV rays. TDK'southward unique algorithm enables the automatic recording of the hours spent sleeping using an acceleration sensor, which monitors the patterns of bodily movements during sleep, then automatically analyzes the monitoring data to determine whether the wearer is awake or sleeping.
Wristband type active mass meter Silmee™ W22
The pulse meter, which operates 24 hours a day in existent fourth dimension, is based on a reflective photoelectric organization using a green LED and photodiode. The green LED emits calorie-free onto the skin of the wrist, and the light receiving element, the photodiode, measures the light diffuse-reflection of the capillaries 1 to 2 mm deep under the peel.
The heartbeat dictates the dilation and contraction of the capillaries nether the skin in the wrists, and the hemoglobin in the claret absorbs light. So, when the capillaries are dilated, there is more blood that runs through them, reducing the calorie-free that bounces back to the photodiode. Conversely, contracted capillaries allow more than lite to be reflected, since less blood runs through them. By wearing the device, a person's pulse tin can exist taken in real fourth dimension 24/7. Continuous measurement of your pulse is useful to observe out the exercise load optimal for your age. The device is thus a reliable tool to assist daily preparation and healthcare.
It is designed to fit various occasions and comes with an easy-to-read display. Fully charged it runs for 10 consecutive days. The device has a chapters to shop about ane month's worth of active mass data (these figures are only estimates, and may vary depending on the conditions of use). The defended app, Silmee Connect, allows users to display and manage the vital data obtained through the sensors on their smartphones.
