Paceband Example
{{Use dmy dates, date=January 2023 A paceband is a wristband, sometimes made of a strip of waterproof paper, that lists expected split times for a running race. When used in conjunction with a stopwatch, a paceband can assist athletes in maintaining a steady pace throughout the race. This is the most efficient racing pace from a cardiovascular and muscle energy perspective. Erratic running speeds, particularly the urge to sprint early in a race while feeling fresh, consume energy inefficiently. A glance at the paceband and stopwatch as each distance marker is passed allows the athlete to quickly determine if they are running too fast for their targeted finishing time or too slowly and adjust accordingly. Pre-printed versions for a variety of target finishing times can often be obtained before endurance races such as marathon The marathon is a long-distance foot race with a distance of kilometres ( 26 mi 385 yd), usually run as a road race, but the distance can be covered o ...

Wristband
Wristbands are encircling strips worn on the wrist or lower forearm. The term may refer to a bracelet-like band, similar to that of a watch, wristwatch, to the cuff or other part of a sleeve that covers the wrist, or decorative or functional bands worn on the wrist for many different reasons. Wristbands are often worn and used similarly to event passes such as lanyards to information or allow people entry to events. These wristbands are made from loops of plastic that are placed around the wrist and are used for identification purposes (demonstrating the wearer's authorization to be at a Music venue, venue, for example). Another type of wristband is the sweatband; usually made of a towel-like terrycloth material. These are usually used to wipe sweat from the forehead during sport but have been known to be used as a badge or fashion statement. A practice common in mid-1980s punk subculture was to cut the top off of a sock and fashion the Elastomer, elastic into this type of wri ...

Waterproof Paper
Waterproof paper uses special coatings (plastic-coated paper) and fibers to enhance durability, dimensional stability, tear resistance and resistance to changing shape or texture when exposed to water. The paper has applications for wet or damp environments, including outdoor, marine, field uses as well as printing applications for similar environments. The paper presents recycling challenges. Historically, waterproof paper was described in ''Scientific American'' in 1884. See also * Greaseproof paper *Liquid packaging board *Tyvek *Waterproofing Waterproofing is the process of making an object, person or structure waterproof or water-resistant so that it remains relatively unaffected by water or resists the ingress of water under specified conditions. Such items may be used in wet env ... * Wet strength References Coated paper Paper {{Material-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Racing
In sports, racing is a competition of speed, in which competitors try to complete a given task in the shortest amount of time. Typically this involves traversing some distance, but it can be any other task involving speed to reach a specific goal. A race may be run continuously to finish or may be made up of several segments called heats, stages or legs. A heat is usually run over the same course at different times. A stage is a shorter section of a much longer course or a time trial. Early records of races are evident on pottery from ancient Greece, which depicted running men vying for first place. A chariot race is described in Homer's ''Iliad''. Etymology The word ''race'' comes from a Norse word. This Norse word arrived in France during the invading of Normandy and gave the word ''raz'' which means "swift water" in Brittany, as in a mill race; it can be found in " Pointe du Raz" (the most western point of France, in Brittany), and "''raz-de-marée''" (tsunami).

Stopwatch
A stopwatch is a timepiece designed to measure the amount of time that elapses between its activation and deactivation. A large digital version of a stopwatch designed for viewing at a distance, as in a sports stadium, is called a stop clock. In manual timing, the clock is started and stopped by a person pressing a button. In fully automatic time, both starting and stopping are triggered automatically, by sensor. The timing functions are traditionally controlled by two buttons on the case. Pressing the top button starts the timer running, and pressing the button a second time stops it, leaving the elapsed time displayed. A press of the second button then resets the stopwatch to zero. The second button is also used to record ''split times'' or ''lap times''. When the split time button is pressed while the watch is running it allows the elapsed time to that point to be read, but the watch mechanism continues running to record total elapsed time. Pressing the split button a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardiovascular Exercise
Aerobic exercise, also known as cardio, is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. "Aerobic" is defined as "relating to, involving, or requiring oxygen", and refers to the use of oxygen to meet energy demands during exercise via aerobic metabolism adequately. Aerobic exercise is performed by repeating sequences of light-to-moderate intensity activities for extended periods of time. According to the World Health Organization, over 31% of adults and 80% of adolescents fail to maintain the recommended levels of physical activity. Examples of cardiovascular or aerobic exercise are medium- to long-distance running or jogging, swimming, cycling, stair climbing and walking. For reducing the risk of health issues, 2.5 hours of moderate-intensity aerobic exercise per week is recommended. At the same time, even doing an hour and a quarter (11 minutes/day) of exercise can reduce the risk of early death, cardiovascular disea ...

Muscle Energy Technique
Muscle Energy Techniques (METs) describes a broad class of manual therapy techniques directed at improving musculoskeletal function or joint function, and improving pain. METs are commonly used by manual therapists, physical therapists, occupational therapist, chiropractors, athletic trainers, osteopathic physicians, and massage therapists. Muscle energy requires the patient to actively use his or her muscles on request to aid in treatment. Muscle energy techniques are used to treat somatic dysfunction, especially decreased range of motion, muscular hypertonicity, and pain. Historically, the concept emerged as a form of osteopathic manipulative diagnosis and treatment in which the patient's muscles are actively used on request, from a precisely controlled position, in a specific direction, and against a distinctly executed physician counterforce. It was first described in 1948 by Fred Mitchell, Sr, D.O. Pathophysiology Injury can occur as a result of trauma, accidents, overuse ...

Sportsperson
An athlete is most commonly a person who competes in one or more sports involving physical strength, speed, power, or endurance. Sometimes, the word "athlete" is used to refer specifically to sport of athletics competitors, i.e. including track and field and marathon runners but excluding e.g. swimmers, footballers or basketball players. However, in other contexts (mainly in the United States) it is used to refer to all athletics (physical culture) participants of any sport. For the latter definition, the word sportsperson or the gendered sportsman or sportswoman are also used. A third definition is also sometimes used, meaning anyone who is physically fit regardless of whether they compete in a sport. Athletes may be professionals or amateurs. Most professional athletes have particularly well-developed physiques obtained by extensive physical training and strict exercise, accompanied by a strict dietary regimen. Definitions The word "athlete" is a romanization of the , ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long-distance Running
Long-distance running, or endurance running, is a form of continuous running over distances of at least . Physiologically, it is largely aerobic in nature and requires stamina as well as mental strength. Within endurance running come two different types of respiration. The more prominent side that runners experience more frequently is aerobic respiration. This occurs when oxygen is present, and the body can utilize oxygen to help generate energy and muscle activity. On the other side, anaerobic respiration occurs when the body is deprived of oxygen, and this is common towards the final stretch of races when there is a drive to speed up to a greater intensity. Overall, both types of respiration are used by endurance runners quite often, but are very different from each other. Among mammals, humans are well adapted for running significant distances, particularly so among primates. The capacity for endurance running is also found in migratory ungulates and a limited number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marathon
The marathon is a long-distance foot race with a distance of kilometres ( 26 mi 385 yd), usually run as a road race, but the distance can be covered on trail routes. The marathon can be completed by running or with a run/walk strategy. There are also wheelchair divisions. More than 800 marathons are held worldwide each year, with the vast majority of competitors being recreational athletes, as larger marathons can have tens of thousands of participants. A creation of the French philologist Michel Bréal inspired by a story from Ancient Greece, the marathon was one of the original modern Olympic events in 1896 in Athens. The distance did not become standardized until 1921. The distance is also included in the World Athletics Championships, which began in 1983. It is the only running road race included in both championship competitions (walking races on the roads are also contested in both). History Origin The name ''Marathon'' comes from the legend of Pheidippides, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Running
Running is a method of terrestrial locomotion by which humans and other animals move quickly on foot. Running is a gait with an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, a slower form of movement where at least one foot is always in contact with the ground, the legs are kept mostly straight, and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.Biewener, A. A. 2003. Animal Locomotion. Oxford University Press, US. books.google.com/ref> A feature of a running body from the viewpoint of Spring mass system, spring-mass mechanics is that changes in Kinetic energy, kinetic and potential energy within a stride co-occur, with energy storage accomplished by springy tendons and passive muscle elasticity. The term "running" can refer to a variety of speeds ranging from jogging to Sprint (running), sprinting. Running in humans is associated with improved health and life expect ...
