Isokinetic Exercise
Strength training, also known as weight training or resistance training, is exercise designed to improve physical strength. It is often associated with the lifting of weights. It can also incorporate techniques such as bodyweight exercises (e.g., push-ups, pull-ups, and squats), isometrics (holding a position under tension, like planks), and plyometrics (explosive movements like jump squats and box jumps). Training works by progressively increasing the force output of the muscles and uses a variety of exercises and types of equipment. Strength training is primarily an anaerobic activity, although circuit training also is a form of aerobic exercise. Strength training can increase muscle, tendon, and ligament strength as well as bone density, metabolism, and the lactate threshold; improve joint and cardiac function; and reduce the risk of injury in athletes and the elderly. For many sports and physical activities, strength training is central or is used as part of their trai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lactate Threshold
Lactate inflection point (LIP) is the exercise intensity at which the blood concentration of lactate and/or lactic acid begins to increase rapidly. It is often expressed as 85% of maximum heart rate or 75% of maximum oxygen intake. When exercising at or below the lactate threshold, any lactate produced by the muscles is removed by the body without it building up. The onset of blood lactate accumulation (OBLA) is often confused with the lactate threshold. With an exercise intensity higher than the threshold the lactate production exceeds the rate at which it can be broken down. The blood lactate concentration will show an increase equal to 4.0 mM; it then accumulates in the muscle and then moves to the bloodstream. Regular endurance exercise leads to adaptations in skeletal muscle which raises the threshold at which lactate levels will rise. This is mediated via activation of the protein receptor PGC-1α, which alters the isoenzyme composition of the lactate dehydrogenase (L ...

Valsalva Maneuver
The Valsalva maneuver is performed by a forceful attempt of exhalation against a closed airway, usually done by closing one's mouth and pinching one's nose shut while expelling air, as if blowing up a balloon. Variations of the maneuver can be used either in medicine, medical examination as a test of cardiac function and autonomic nervous system, autonomic nervous control of the heart (because the maneuver raises the pressure in the lungs), or to clear the ears and paranasal sinuses, sinuses (that is, to equalize pressure between them) when ambient pressure changes, as in scuba diving, hyperbaric oxygen therapy, or air travel. A modified version is done by expiring against a closed glottis. This will elicit the cardiovascular responses described below but will not force air into the Eustachian tubes. History The technique is named after Antonio Maria Valsalva, a 17th-century physician and anatomist from Bologna whose principal scientific interest was the human ear. He descri ...

Powerlifting
Powerlifting is a competitive strength athletics, strength sport that consists of three attempts at maximal weight on three lifts: Squat (exercise), squat, bench press, and deadlift. As in the sport of Olympic weightlifting, it involves the athlete attempting a maximal weight single-lift effort of a barbell loaded with weight plates. Powerlifting evolved from a sport known as "odd lifts", which followed the same three-attempt format but used a wider variety of events, akin to Strength athletics, strongman competition. Eventually, odd lifts became standardized to the current three. In competition, lifts may be performed equipped or unequipped (typically referred to as 'classic' or 'raw' lifting in the International Powerlifting Federation, IPF specifically). Equipment in this context refers to a supportive bench shirt or squat/deadlift suit or briefs. In some federations, knee wraps are permitted in the equipped but not unequipped division; in others, they may be used in both equip ...

Heart Rate
Heart rate is the frequency of the cardiac cycle, heartbeat measured by the number of contractions of the heart per minute (''beats per minute'', or bpm). The heart rate varies according to the body's Human body, physical needs, including the need to absorb oxygen and excrete carbon dioxide. It is also modulated by numerous factors, including (but not limited to) genetics, physical fitness, Psychological stress, stress or psychological status, diet, drugs, hormonal status, environment, and disease/illness, as well as the interaction between these factors. It is usually equal or close to the pulse rate measured at any peripheral point. The American Heart Association states the normal resting adult human heart rate is 60–100 bpm. An ultra-trained athlete would have a resting heart rate of 37–38 bpm. ''Tachycardia'' is a high heart rate, defined as above 100 bpm at rest. ''Bradycardia'' is a low heart rate, defined as below 60 bpm at rest. When a human sleeps, a heartbeat with ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blood Pressure
Blood pressure (BP) is the pressure of Circulatory system, circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured. Blood pressure is usually expressed in terms of the systolic pressure (maximum pressure during one Cardiac cycle, heartbeat) over diastolic pressure (minimum pressure between two heartbeats) in the cardiac cycle. It is measured in Millimetre of mercury, millimetres of mercury (mmHg) above the surrounding atmospheric pressure, or in Pascal (unit), kilopascals (kPa). The difference between the systolic and diastolic pressures is known as pulse pressure, while the average pressure during a cardiac cycle is known as mean arterial pressure. Blood pressure is one of the vital signs—together with respiratory rate, heart rate, Oxygen saturation (me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warming Up
'Warming up' is a part of stretching and preparation for physical exertion or a performance by exercising or practicing gently beforehand, usually undertaken before a performance or practice. Athletes, singers, actors and others warm up before stressing their muscles. It is widely believed to prepare the muscles for vigorous actions and to prevent muscle cramps and injury due to overexertion. Exercise A warm-up generally consists of a gradual increase in intensity in physical activity (a "pulse raiser"), joint mobility exercise, and stretching, followed by the activity. For example, before running or playing an intensive sport, athletes might slowly jog to warm their muscles and increase their heart rate. It is important that warm-ups be specific to the activity, so that the muscles to be used are activated. The risks and benefits of combining stretching with warming up are disputable, although it is generally believed that warming up prepares the athlete both mentally and ph ...

Neurological
Neurology (from , "string, nerve" and the suffix -logia, "study of") is the branch of medicine dealing with the diagnosis and treatment of all categories of conditions and disease involving the nervous system, which comprises the brain, the spinal cord and the peripheral nerves. Neurological practice relies heavily on the field of neuroscience, the scientific study of the nervous system, using various techniques of neurotherapy. IEEE Brain (2019).

Cheating
Cheating generally describes various actions designed to subvert or disobey rules in order to obtain unfair advantages without being noticed. This includes acts of bribery, cronyism and nepotism in any situation where individuals are given preference using inappropriate criteria. The rules infringed may be explicit, or they may be from an unwritten code of conduct based on morality, ethics or custom, making the identification of cheating conduct a potentially subjective process. Cheating can refer specifically to infidelity, where arranged or consensual relationships, that often come with a social contract, are violated. Someone who is known for cheating is referred to as a ''cheat'' in British English, and a ''cheater'' in American English. Academic Academic cheating is a significantly common occurrence in high schools and colleges in the United States. Statistically, 64% of public high school students admit to serious test cheating. 58% say they have plagiarized. 95% of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Form (exercise)

Form is a specific way of performing a movement, often a strength training Strength training, also known as weight training or resistance training, is exercise designed to improve physical strength. It is often associated with the lifting of Weightlifting, weights. It can also incorporate techniques such as bodyweigh ... exercise, to avoid injury and maximize benefit. Purposes Exercises or drills in sport have recognized ways of performing movements for two purposes: Avoiding injury By using good and proper form, the risk of injury is lowered. A lack of proper form commonly results in injury or a lack of effect from the exercise being performed Maximizing benefit Good form ensures that the movement only uses the main muscles, and avoids recruiting secondary muscles. As a muscle fatigues, the body attempts to compensate by recruiting other muscle groups and transferring force generation to non-fatigued units. This re ...

Action Potential
An action potential (also known as a nerve impulse or "spike" when in a neuron) is a series of quick changes in voltage across a cell membrane. An action potential occurs when the membrane potential of a specific Cell (biology), cell rapidly rises and falls. This depolarization then causes adjacent locations to similarly depolarize. Action potentials occur in several types of Membrane potential#Cell excitability, excitable cells, which include animal cells like neurons and myocyte, muscle cells, as well as some plant cells. Certain endocrine cells such as pancreatic beta cells, and certain cells of the anterior pituitary gland are also excitable cells. In neurons, action potentials play a central role in cell–cell interaction, cell–cell communication by providing for—or with regard to saltatory conduction, assisting—the propagation of signals along the neuron's axon toward axon terminal, synaptic boutons situated at the ends of an axon; these signals can then connect wit ...
