[No.6 The decathlon and heptathlon] What is the decathlon and the heptathlon?
Athletes compete in a combination of running, jumping, and throwing events for two 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 King of Athletes and the Queen of Athletes, respectively.
These sports take 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 ways a directly alley of about 200m, and is the root of the word "stadium" in English. The suffix -athlon, equally in decathlon and heptathlon, comes from the Greek word for "contest," and some English language words like athlete and athletics are besides related to the give-and-take.
In the decathlon and heptathlon, the following events are competed in over two consecutive days. The sports crave athletes to perform running, jumping, and throwing events ane later on another, besides as managing their fourth dimension for warming upward and practicing before the competition, and then cooling down and taking breaks between events, for which fantabulous physical competence and perseverance are vital prerequisites, equally is mental toughness. For this reason, they are known as the hardest of all track and field sports. Of course, regular training is necessary for all of the events.
Their records (time and altitude) are converted into points by designated conversion formulas, with the full score determining the ranking order.
The formulas are very complex, take for example the 100m sprint. Information technology is calculated every bit score = 4347 x (18-T)1.81 [points], where T is the recorded time (2nd). This tin be calculated using a scientific calculator, today apps for PCs and smartphones are available which calculate scores simply by inbound the recorded times or distances. Hither are the earth's elevation x decathlon records.
The current world tape in the decathlon is 9126 points, achieved by Kevin Mayer in 2018. The previous world record was held by Ashton Eaton from IAAF World Athletics Championships Beijing 2015, where the new world tape of 9045 points was achieved for the beginning time in 14 years. Mayer easily broke this record with his amazing points score, exceeding information technology by nearly 100 points.
While Mayer's records in the short and heart-distance runs barbarous brusque of those of Eaton's, his skillful results in the throwing events (shot put, discus and javelin throws), which he is potent in, considerably contributed to his overall score, allowing him to found a new world record.
Take a expect at the comparisons betwixt his results (times and distances) from the championship and globe records in each event. Although Mayer is good in the throwing events, the results were not even close to the world records of individual events. As he is withal a young athlete, born in 1992, Mayer draws the world'south attention for his potential to further progress in the throwing events, and meliorate on his world record in the time to come.
The globe record in the heptathlon remains unbroken for over xxx years
Here are the women's top x heptathlon records. In this sport the electric current earth tape is held by Jackie Joyner-Kersee, with 7291 points, which she achieved in 1988. The second best score is 7032 points past Carolina Klüft in 2007, lagging behind the world's top by a staggering 259 points, which creates intrigue as to who is going to pause this outstanding earth record.
A stadium offers a unique experience of spectating at track and field events at one fourth dimension
The decathlon and heptathlon both accept place over ii consecutive days in the same stadium. A stadium offers the unique experience of watching the rail and field events simultaneously among other enthused spectators. Here is a uncomplicated analogy of an athletics stadium. Official stadiums where international and other of import competitions have place are equipped with several areas for jumping and throwing events, assuasive the contest 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 past Jan Železný (1996). You may recollect that it is only a question of time before nosotros see the 100m mark broken, but in fact it was already achieved in 1984, when the globe's start over a 100 meters record was achieved (104.8m). However, information technology was felt that the turfed area would be too short if the record continued to abound over 100 meters, and then the rules were changed to shift the center of gravity of the javelin toward its front end and so that the flying distance would be shortened by about 10%. Today, the official world records for men and women are the ones achieved after 1986 and 1999 respectively.
The last event of the decathlon and heptathlon is the heart altitude run (men's 1500m and women's 800m), which is extremely hard for athletes physically every bit well equally mentally, because the title of being the king or queen of athletes volition be snatched away by others if they neglect to beat competitors in the total score, even if they cantankerous the stop line earlier everyone else. It is exciting to see in this race how athletes play out their strategies against rivals and squeeze out their remaining forcefulness in their concluding spurt.
TDK's sensors and sensing engineering, supporting sports science and athletes' healthcare
Growing efforts are being made to leverage sensors and sensing technology to ameliorate sports such as rail and field events efficiently and effectively. For example, motion sensors (dispatch sensors and athwart velocity sensors) are employed to analyze athletes' bodily movements and postures while biosensors measure their heartbeat, breathing, body temperature, perspiration and so on, so equally to monitor their physical condition. Environmental sensors serve as a means of finding the correlation between operation and the environment by measuring the ambient temperature, humidity, and atmospheric pressure. The information can and then be analyzed using artificial intelligence (AI) to explore further improvements in rail and field events, equally well every bit other sports.
Sensors and sensing technology are likewise used in devices such as agile mass meters that record athletes' daily training sessions.
TDK offers a wearable biosensor, the Silmee™ series, for collecting and managing vital data, such equally the amount of exercise and pulse charge per unit, by combining high-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. It can measure and record steps made while running or walking, the calories consumed during practise, as well as the hours comatose, pulse rate, pare temperature, and the amount of UV rays. TDK'south unique algorithm enables the automated recording of the hours spent sleeping using an acceleration sensor, which monitors the patterns of actual movements during sleep, and so automatically analyzes the monitoring information to decide whether the wearer is awake or sleeping.

The pulse meter, which operates 24 hours a day in existent time, is based on a reflective photoelectric system using a green LED and photodiode. The light-green LED emits light 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 nether the skin.
The heartbeat dictates the dilation and wrinkle of the capillaries under the pare in the wrists, and the hemoglobin in the claret absorbs lite. So, when the capillaries are dilated, there is more blood that runs through them, reducing the lite that bounces back to the photodiode. Conversely, contracted capillaries allow more than light to be reflected, since less blood runs through them. Past wearing the device, a person'south pulse can be taken in real time 24/vii. Continuous measurement of your pulse is useful to find out the do load optimal for your age. The device is thus a reliable tool to assist daily training and healthcare.
Information technology is designed to fit diverse occasions and comes with an easy-to-read brandish. Fully charged it runs for ten sequent days. The device has a capacity to store about one month's worth of active mass information (these figures are only estimates, and may vary depending on the weather of employ). The dedicated app, Silmee Connect, allows users to display and manage the vital data obtained through the sensors on their smartphones.
