스트렝스 트레이닝은 힘, 무산소 지구력, 골격근의 크기를 만드는 근수축을 유발시키는 저항력을 이용하는 신체 운동의 한 형식이다.
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, increased bone density, increased metabolism, increased fitness, improved cardiac function, and improved lipoprotein lipid profiles, including elevated HDL ("good") cholesterol.
적절하게 수행을 했을 경우, 스트렝스 트레이닝은 굉장한 기능적 이점들과 강화된 뼈, 근육, 건, 인대 힘, 강인함, 향상된 관절 기능, 잠재적인 부상 감소, 뼈밀도 증가, 신진대사 증가, 체력 증가, 향상된 심페 기능, 향상된 리포단백질 지질대사지표와 HDL 콜레스테롤의 증가를 포함한 웰빙과 건강의 전반적인 향상을 제공한다.
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.
트레이닝은 보통 점진적인 중량 증가를 통해 근육의 힘출력을 점진적으로 증가하는 기술을 이용하며 다양한 운동과 장비를 이용하여 특정한 근육그룹을 타겟으로 한다.
Strength training is typically associated with the production of lactate, which is a limiting factor of exercise performance. 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.
