Strength training Wikipedia. This article is about the basic principles to train muscular strength. For strength training using free weights or weight machines, see weight training. Strength training is a type of physical exercise specializing in the use of resistance to induce muscular contraction which builds the strength, anaerobic endurance, and size of skeletal muscles. When properly performed, strength training can provide significant functional benefits and improvement in overall health and well being, including increased bone, muscle, tendon, and ligament strength and toughness, improved joint function, reduced potential for injury,1 increased bone density, increased metabolism, increased fitness,23 improved cardiac function, and improved lipoprotein lipid profiles, including elevated HDL good cholesterol. Training commonly uses the technique of progressively increasing the force output of the muscle through incremental weight increases and uses a variety of exercises and types of equipment to target specific muscle groups. Strength training is primarily an anaerobic activity, although some proponents have adapted it to provide the benefits of aerobic exercise through circuit training.

Drivers Commodore Ke-8327-Mb on this page. Regular endurance exercise leads to adaptations in skeletal muscle which can prevent lactate levels from rising during strength training. This is mediated via activation of PGC 1alpha which alter the LDH lactate dehydrogenase isoenzyme complex composition and decreases the activity of the lactate generating enzyme LDHA, while increasing the activity of the lactate metabolizing enzyme LDHB. Sports where strength training is central are bodybuilding, weightlifting, powerlifting, strongman, Highland games, shotput, discus throw, and javelin throw. Many other sports use strength training as part of their training regimen, notably tennis, American football, wrestling, track and field, rowing, lacrosse, basketball, pole dancing, hockey, professional wrestling, rugby union, rugby league, and soccer. Strength training for other sports and physical activities is becoming increasingly popular. The benefits of weight training include greater muscular strength, improved muscle tone and appearance, increased endurance and enhanced bone density. Increased physical attractivenesseditMany people take up weight training to improve their physical attractiveness. Find great deals on eBay for hydraulic crimper and hydraulic hose crimper.

There is evidence that a body type consisting of broad shoulders and a narrow waist, attainable through strength training, is the most physically attractive male attribute according to women participating in the research. Most men can develop substantial muscles most women lack the testosterone to do it, but they can develop a firm, toned see below physique, and they can increase their strength by the same proportion as that achieved by men but usually from a significantly lower starting point. An individuals genetic make up dictates the response to weight training stimuli to a significant extent, training can not exceed a muscles intrinsic genetically determined qualities, but clearly polymorphic expression of Myosin heavy chains is possible. Workouts elevate metabolism for up to 1. Increased general physical healtheditStrength training also provides functional benefits. Stronger muscles improve posture, provide better support for joints, and reduce the risk of injury from everyday activities. Older people who take up weight training can prevent some of the loss of muscle tissue that normally accompanies agingand even regain some functional strengthand by doing so become less frail.

Weight bearing exercise also helps to prevent osteoporosis and to improve bone strength in those with osteoporosis. The benefits of weight training for older people have been confirmed by studies of people who began engaging in it even in their 8. Though strength training can stimulate the cardiovascular system, many exercise physiologists, based on their observation of maximal oxygen uptake, argue that aerobics training is a better cardiovascular stimulus.

Central catheter monitoring during resistance training reveals increased cardiac output, suggesting that strength training shows potential for cardiovascular exercise. However, a 2. 00. Strength training may be important to metabolic and cardiovascular health. Recent evidence suggests that resistance training may reduce metabolic and cardiovascular disease risk. Overweight individuals with high strength fitness exhibit metaboliccardiovascular risk profiles similar to normal weight, fit individuals rather than overweight unfit individuals. For rehabilitation or to address an impairmenteditFor many people in rehabilitation or with an acquired disability, such as following stroke or orthopaedic surgery, strength training for weak muscles is a key factor to optimise recovery. For people with such a health condition, their strength training is likely to need to be designed by an appropriate health professional, such as a physiotherapist or an occupational therapist. Increased sports performanceeditStronger muscles improve performance in a variety of sports. Sport specific training routines are used by many competitors. These often specify that the speed of muscle contraction during weight training should be the same as that of the particular sport. For the pleasure of the activityeditOne side effect of intense exercise is increased levels of dopamine, serotonin, and norepinephrine, which can help to improve mood and counter feelings of depression It should be noted that dopamine and serotonin were not found to be increased by resistance training. Developing research has demonstrated that many of the benefits of exercise are mediated through the role of skeletal muscle as an endocrine organ. That is, contracting muscles release multiple substances known as myokines which promote the growth of new tissue, tissue repair, and various anti inflammatory functions, which in turn reduce the risk of developing various inflammatory diseases. TechniqueeditThe basic principles of strength training involve a manipulation of the number of repetitions reps, sets, tempo, exercises and force to cause desired changes in strength, endurance or size by overloading of a group of muscles. The specific combinations of reps, sets, exercises, resistance and force depend on the purpose of the individual performing the exercise to gain size and strength multiple 4 sets with fewer reps must be performed using more force.

A wide spectrum of regimens can be adopted to achieve different results, but the classic formula recommended by the American College of Sports Medicine reads as follows 8 to 1. RM depending on the training level of the participant. Two to three minutes of rest is recommended between exercise sets to allow for proper recovery. Two to four sets are recommended for each muscle group2. Typically failure to use good form during a training set can result in injury or an inability to meet training goals since the desired muscle group is not challenged sufficiently, the threshold of overload is never reached and the muscle does not gain in strength.
