Tapering (sports)
In sports, tapering is the practice of reducing exercise in the days just before an important competition. Tapering is customary both in endurance sports, such as long-distance running and swimming, and strength sports, such as weightlifting and sprinting. For many athletes, a significant period of tapering is essential for optimal performance. The tapering period frequently lasts as much as a week or more. This tapering means gradually reducing the exercise over a short period of time then stopping completely when leading up to competitions. Tapering periods As a general rule of thumb, longer endurance events are generally preceded by longer tapering periods, with the curious exception of particularly long endurance competitions, such as ultramarathons and multiday races. In swimming the opposite is true; distance swimmers will often taper for only a week or less, while strength athletes taper for up to 3 weeks. Typically, tapering for relatively short endurance events takes as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sports
Sport is a physical activity or game, often competitive and organized, that maintains or improves physical ability and skills. Sport may provide enjoyment to participants and entertainment to spectators. The number of participants in a particular sport can vary from hundreds of people to a single individual. Sport competitions may use a team or single person format, and may be open, allowing a broad range of participants, or closed, restricting participation to specific groups or those invited. Competitions may allow a "tie" or "draw", in which there is no single winner; others provide tie-breaking methods to ensure there is only one winner. They also may be arranged in a tournament format, producing a champion. Many sports leagues make an annual champion by arranging games in a regular sports season, followed in some cases by playoffs. Sport is generally recognised as system of activities based in physical athleticism or physical dexterity, with major competi ...

Summer Olympic Games
The Summer Olympic Games, also known as the Summer Olympics or the Games of the Olympiad, is a major international multi-sport event normally held once every four years. The 1896 Summer Olympics, inaugural Games took place in 1896 in Athens, then part of the Kingdom of Greece, and the most recent was held in 2024 Summer Olympics, 2024 in Paris, France. This was the first international multi-sport event of its kind, organised by the International Olympic Committee (IOC) founded by Pierre de Coubertin. The tradition of awarding medals began in 1904 Summer Olympics, 1904; in each Olympic Games, Olympic event, gold medals are awarded for first place, silver medals for second place, and bronze medals for third place. The Winter Olympic Games were created out of the success of the Summer Olympic Games, which are regarded as the largest and most prestigious multi-sport international event in the world. The Summer Olympics have increased in scope from a 42-event competition programme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hormone
A hormone (from the Ancient Greek, Greek participle , "setting in motion") is a class of cell signaling, signaling molecules in multicellular organisms that are sent to distant organs or tissues by complex biological processes to regulate physiology and behavior. Hormones are required for the normal development of animals, plants and fungi. Due to the broad definition of a hormone (as a signaling molecule that exerts its effects far from its site of production), numerous kinds of molecules can be classified as hormones. Among the substances that can be considered hormones, are eicosanoids (e.g. prostaglandins and thromboxanes), steroids (e.g. Estrogen, oestrogen and brassinosteroid), amino acid derivatives (e.g. epinephrine and auxin), protein or peptides (e.g. insulin and CLE peptides), and gases (e.g. ethylene and nitric oxide). Hormones are used to communicate between organ (anatomy), organs and Tissue (biology), tissues. In vertebrates, hormones are responsible for regulating ...

Antioxidant
Antioxidants are Chemical compound, compounds that inhibit Redox, oxidation, a chemical reaction that can produce Radical (chemistry), free radicals. Autoxidation leads to degradation of organic compounds, including living matter. Antioxidants are frequently added to industrial products, such as polymers, fuels, and lubricants, to extend their usable lifetimes. Foods are also treated with antioxidants to prevent Food spoilage, spoilage, in particular the rancidification of Vegetable oil, oils and fats. In Cell (biology), cells, antioxidants such as glutathione, mycothiol, or bacillithiol, and enzyme systems like superoxide dismutase, inhibit damage from oxidative stress. Known diet (nutrition), dietary antioxidants are vitamins vitamin A, A, vitamin C, C, and vitamin E, E, but the term has also been applied to various compounds that exhibit antioxidant properties in vitro, having little evidence for antioxidant properties in vivo. Dietary supplements marketed as antioxidants hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enzyme
An enzyme () is a protein that acts as a biological catalyst by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different molecules known as product (chemistry), products. Almost all metabolism, metabolic processes in the cell (biology), cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme, pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts include Ribozyme, catalytic RNA molecules, also called ribozymes. They are sometimes descr ...

Glycogen
Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals, fungi, and bacteria. It is the main storage form of glucose in the human body. Glycogen functions as one of three regularly used forms of energy reserves, creatine phosphate being for very short-term, glycogen being for short-term and the triglyceride stores in adipose tissue (i.e., body fat) being for long-term storage. Protein, broken down into amino acids, is seldom used as a main energy source except during starvation and glycolytic crisis ''(see bioenergetic systems)''. In humans, glycogen is made and stored primarily in the cells of the liver and skeletal muscle. In the liver, glycogen can make up 5–6% of the organ's fresh weight: the liver of an adult, weighing 1.5 kg, can store roughly 100–120 grams of glycogen. In skeletal muscle, glycogen is found in a low concentration (1–2% of the muscle mass): the skeletal muscle of an adult weighing 70 ...

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] |
Multiday Race
Multiday races are ultramarathon running events which are typically either segmented into daily events of a specified distance or time, or staged so that runners can run as far as they want, at their own discretion, over a set course or over a set number of days. Multiday races can range from continuous 48-hour track events to staged transcontinental treks. Beyond the marathon Very long endurance running events can be divided into three broad categories: the traditional marathon, the ultramarathon, defined as any event longer than the marathon, and true multiday events, which begin with the 24-hour event and can stretch out almost indefinitely, often ranging from six days to or longer. Multiday events are usually timed races such as 48-hour, 72-hour and 6 day races. Set distance races depend on the ability of the runner to complete and what may be a multiday for slower runners may be an ultra to faster athletes. For example the Badwater Ultramarathon, a race, has a 48 hour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultramarathon
An ultramarathon is a footrace longer than the traditional marathon distance of . The sport of running ultramarathons is called ultra running or ultra distance running. Various distances, surfaces, and formats are raced competitively, from the shortest common ultramarathon of and up to 3100 miles. Around is typically the longest course distance raced in under 24 hours, but there are also longer multiday races commonly held as 48 hours, , or more, sometimes raced in stages with breaks for sleep. The oldest and largest ultramarathons are on road, including the Comrades Marathon (more than 10,000 finishers annually) and Two Oceans Marathon (more than 6,000 finishers annually). The world's longest certified footrace is the Self-Transcendence 3100 Mile Race. Many ultras have historical significance, including the Spartathlon, based on the 246 km run of Greek messenger Pheidippides from Athens to Sparta during the Battle of Marathon in a day and a half to seek aid against t ...
