Paceband
{{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 , usually run as a road race, but the distance can be covered on trail routes.

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 comes 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 is able to 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, and particularly so among primates. The capacity for endurance running is also found in migratory ungulates and a li ...

Wristband
Wristbands are encircling strips worn on the wrist or lower forearm. The term can be used to refer to a bracelet-like band, similar to that of a 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 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 elastic into this type of wristband. Silicone w ...

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 *Wet strength The wet strength of paper and paperboard is a measure of how well the web of fibers holding the paper together can resist a force of rupture when the paper is wet. Wet strength is routinely expressed as the ratio of wet to dry tensile force at bre ... References Coated paper Paper {{Material-stub ...

Racing
In sport, 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 sensors. 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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardiovascular Exercise
Aerobic exercise (also known as endurance activities, cardio or cardio-respiratory exercise) 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. Aerobic exercise may be better referred to as "solely aerobic", as it is designed to be low-intensity enough that all carbohydrates are aerobically turned into energy via mitochondrial ATP production. Mitochondria are organelles that rely on oxygen for the metabolism of carbs, proteins, and fats. Examples of cardiovascular or aerobic exercise are medium- to long-distance running or jogging, swimming, cycling, stair climbing and walking. History Archibald Hill, a British physiolo ...

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, overus ...

Sportsperson
An athlete (also sportsman or sportswoman) is a person who competes in one or more sports that involve physical strength, speed, or endurance. 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 el, άθλητὴς, ''athlētēs'', one who participates in a contest; from ἄθλος, ''áthlos'' or ἄθλον, ''áthlon'', a contest or feat. The primary definition of "sportsman" according to Webster's ''Third Unabridged Dictionary'' (1960) is, "a person who is active in sports: as (a): one who engages in the sports of the field and especially in hunting or fishing." Physiology Athletes involved in isotonic exercises have an increased mean left ventricular end-diastolic volume and are less likely to be depressed. Due to their strenuous physical activities, ...

Marathon
The marathon is a long-distance foot race with a distance of , 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 throughout the world each year, with the vast majority of competitors being recreational athletes, as larger marathons can have tens of thousands of participants. The marathon was one of the original modern Olympic events in 1896. 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 Philippides (or Pheidippides), the Greek messenger. The legend states that, while he was taking part in the Battle of Marathon, whi ...

Running
Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where 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 mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to Sprint (running), sprinting. Running in humans is associated with improved health and life expectancy.
