Endurance Athlete
Endurance training is the act of exercising to increase endurance. The term endurance training generally refers to training the aerobic system as opposed to the anaerobic system. The need for endurance in sports is often predicated as the need of cardiovascular and simple muscular endurance, but the issue of endurance is far more complex. Endurance can be divided into two categories including: general endurance and specific endurance. Endurance in sport is closely tied to the execution of skill and technique. A well conditioned athlete can be defined as, the athlete who executes his or her technique consistently and effectively with the least effort. Key for measuring endurance are heart rate, power in cycling and pace in running. Endurance in sports Endurance training is essential for a variety of endurance sports. A notable example is distance running events (800 meters upwards to marathon and ultra-marathon) with the required degree of endurance training increasing with ra ...

Biking At Pass'Portes Du Soleil MTB Festival
Cycling, also known as bicycling or biking, is the activity of riding a bicycle or other types of bicycle pedal, pedal-driven human-powered vehicles such as balance bikes, unicycles, tricycles, and quadricycles. Cycling is practised around the world for purposes including transport, recreation, exercise, and competitive sport. History Cycling became popularized in Europe and North America in the latter part and especially the last decade of the 19th century. Today, over 50 percent of the human population knows how to ride a bike. War The bicycle has been used as a method of reconnaissance as well as transporting soldiers and supplies to combat zones. In this it has taken over many of the functions of horses in warfare. In the Second Boer War, both sides used bicycles for scouting. In World War I, France, Germany, Australia and New Zealand used bicycles to move troops. In its 1937 invasion of China, Japan employed some 50,000 bicycle troops, and similar forces were instrume ...

Cardiac Output
In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols Q, \dot Q, or \dot Q_ , edited by Catherine E. Williamson, Phillip Bennett is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single Ventricle (heart), ventricle of the heart, per unit time (usually measured per minute). Cardiac output (CO) is the product of the heart rate (HR), i.e. the number of heartbeats per minute (bpm), and the stroke volume (SV), which is the volume of blood pumped from the left ventricle per beat; thus giving the formula: :CO = HR \times SV Values for cardiac output are usually denoted as L/min. For a healthy individual weighing 70 kg, the cardiac output at rest averages about 5 L/min; assuming a heart rate of 70 beats/min, the stroke volume would be approximately 70 mL. Because cardiac output is related to the quantity of blood delivered to various parts of the body, it is an important com ...

Heart Rate Monitor
A heart rate monitor (HRM) is a personal monitoring device that allows one to measure/display heart rate in real time or record the heart rate for later study. It is largely used to gather heart rate data while performing various types of physical exercise. Measuring electrical heart information is referred to as Electrocardiography, electrocardiography (ECG or EKG). Medical heart rate monitoring used in hospitals is usually wired and usually multiple sensors are used. Portable medical units are referred to as a Holter monitor. Consumer heart rate monitors are designed for everyday use and do not use wires to connect. History Early models consisted of a monitoring box with a set of electrode leads which attached to the chest. The first wireless EKG heart rate monitor was invented in 1977 by Polar Electro as a training aid for the Finnish National Cross Country Ski team. As "intensity training" became a popular concept in athletic circles in the mid-80s, retail sales of wirel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tudor Bompa
Tudor Olimpius Bompa is a sports scientist. He is a Professor Emeritus at York University in Toronto, Ontario, Canada. He is married to Tamara Bompa, who is an associate lecturer at York University. Background Tudor Olimpius Bompa was born on December 23, 1932, in the town of Năsăud, in Bistrița-Năsăud County, Romania. He attended his first school classes in his hometown, and in 1949 he moved to the Sports School in Cluj-Napoca. During his junior years, he was part of the national athletics team, and won several silver and bronze medals at the National Championships, in the pentathlon, javelin and discus competitions. In his teens, Bompa played competitive soccer and competed in sprint and pentathlon. After an ankle injury, he swapped to rowing, which he found difficult as it is an endurance sport rather than a strength sport that he had been used to through his track and field career. At the 1958 European Rowing Championships, he won a silver medal in the coxed four even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-intensity Interval Training
High-intensity interval training (HIIT) is a training protocol alternating short periods of intense or explosive anaerobic exercise with brief recovery periods until the point of exhaustion. HIIT involves exercises performed in repeated quick bursts at maximum or near maximal effort with periods of rest or low activity between bouts. The very high level of intensity, the interval duration, and number of bouts distinguish it from aerobic (cardiovascular) activity, because the body significantly recruits anaerobic energy systems (although not completely to the exclusion of aerobic pathways). The method thereby relies on "the anaerobic energy releasing system almost maximally". Although there are varying forms of HIIT-style workouts which may involve exercises associated with both cardiovascular activity and also resistance training, HIIT's crucial features of maximal effort, duration, and short rest periods (thereby triggering the anaerobic pathways of energy production) materia ...

Long Slow Distance
Long slow distance (LSD) is a form of aerobic endurance training used in sports including running, rowing, skiing and cycling.Burke, Ed and Ed Pavalka. 2000. ''The complete book of long-distance cycling: build the strength, skills, and confidence to ride as far as you want.'' Rodale . It is also known as aerobic endurance training, base training and Zone 2 training. Physiological adaptations to LSD training include improved cardiovascular function, improved thermoregulatory function, improved mitochondrial energy production, increased oxidative capacity of skeletal muscle, and increased utilization of fat for fuel. Ernst van Aaken, a German physician and coach, is generally recognized as the founder of the LSD method of endurance training.Morris, Alfred F. 1984.

Interval Training
Interval training is a type of training exercise that involves a series of high-intensity workouts interspersed with rest or break periods. The high-intensity periods are typically at or close to anaerobic exercise, while the recovery periods involve activity of lower intensity. Varying the intensity of effort exercises the heart muscle, providing a cardiovascular workout, improving aerobic capacity and permitting the person to exercise for longer and/or at more intense levels. Interval running provides a balanced mix of activity and rest, helping beginners gradually build their stamina and fitness without overexertion. Some interval running exercises include pyramid intervals, hill repeats, and staircase intervals. Soichi Sakamoto, who coached the University of Hawaii, was an early advocate of interval training for his competitive swimmers, and Indiana Coach James Counsilman, who had a Doctorate in Exercise Physiology was highly innovative in advancing the use of interval trai ...

Sports Periodization
Periodization is a cyclical method of planning and managing athletic or physical training and involves progressive cycling of various aspects of a training program during a specific period. Conditioning programs can use periodization to break up the training program into the off-season, preseason, inseason, and the postseason. Periodization divides the year round condition program into phases of training which focus on different goals. History The roots of periodization come from Hans Selye's model, known as the General adaptation syndrome (GAS). The GAS describes three basic stages of response to stress: (a) the Alarm stage, involving the initial shock of the stimulus on the system, (b) the Resistance stage, involving the adaptation to the stimulus by the system, and (c) the Exhaustion stage, in that repairs are inadequate, and a decrease in system function results. The foundation of periodic training is keeping one's body in the resistance stage without ever going into the exha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Testosterone
Testosterone is the primary male sex hormone and androgen in Male, males. In humans, testosterone plays a key role in the development of Male reproductive system, male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of androgenic hair, body hair. It is associated with increased aggression, sex drive, Dominance hierarchy, dominance, courtship display, and a wide range of behavioral characteristics. In addition, testosterone in both sexes is involved in health and well-being, where it has a significant effect on overall mood, cognition, social and sexual behavior, metabolism and energy output, the cardiovascular system, and in the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty, accumulation of adipose fat tissue within the body, anxiety and depression, sexual performance issues, and bone loss.

Cardiac Arrhythmia
Arrhythmias, also known as cardiac arrhythmias, are irregularities in the heartbeat, including when it is too fast or too slow. Essentially, this is anything but normal sinus rhythm. A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a resting heart rate that is too slow – below 60 beats per minute – is called bradycardia. Some types of arrhythmias have no symptoms. Symptoms, when present, may include palpitations or feeling a pause between heartbeats. In more serious cases, there may be lightheadedness, passing out, shortness of breath, chest pain, or decreased level of consciousness. While most cases of arrhythmia are not serious, some predispose a person to complications such as stroke or heart failure. Others may result in sudden death. Arrhythmias are often categorized into four groups: extra beats, supraventricular tachycardias, ventricular arrhythmias and bradyarrhythmias. Extra beats incl ...
