Squat (exercise)
A squat is a strength exercise in which the trainee lowers their hips from a standing position and then stands back up. During the descent and knee joints flex while the ankle joint dorsiflexes; conversely the hip and knee joints extend and the ankle joint plantarflexes when standing up. Squats also help your hip muscles Squats are considered a vital exercise for increasing the strength and size of the lower body muscles as well as developing core strength. The primary agonist muscles used during the squat are the quadriceps femoris, the adductor magnus, and the gluteus maximus. The squat also isometrically uses the erector spinae and the abdominal muscles, among others. The squat is one of the three lifts in the strength sport of powerlifting, together with the deadlift and the bench press. It is also considered a staple exercise in many popular recreational exercise programs. Form The squat begins from a standing position. Weight is often added and is typically in t ...

Powerlifting
Powerlifting is a strength sport that consists of three attempts at maximal weight on three lifts: 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 strongman competition. Eventually odd lifts became standardized to the current three. In competition, lifts may be performed equipped or un-equipped (typically referred to as 'classic' or 'raw' lifting in the 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 un-equipped division; in others, they may be used in both equipped and un-equipped lifting. Weight belts, knee sleeves, wrist wraps, and special footwear may also be u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anterior Cruciate Ligament
The anterior cruciate ligament (ACL) is one of a pair of cruciate ligaments (the other being the posterior cruciate ligament) in the human knee. The two ligaments are also called "cruciform" ligaments, as they are arranged in a crossed formation. In the quadruped stifle joint (analogous to the knee), based on its anatomical position, it is also referred to as the cranial cruciate ligament. The term cruciate translates to cross. This name is fitting because the ACL crosses the posterior cruciate ligament to form an “X”. It is composed of strong, fibrous material and assists in controlling excessive motion. This is done by limiting mobility of the joint. The anterior cruciate ligament is one of the four main ligaments of the knee, providing 85% of the restraining force to anterior tibial displacement at 30 and 90° of knee flexion. The ACL is the most injured ligament of the four located in the knee. Structure The ACL originates from deep within the notch of the distal fe ...

Deep Squat
Squatting is a versatile posture where the weight of the body is on the feet but the knees and hips are bent. In contrast, sitting involves taking the weight of the body, at least in part, on the buttocks against the ground or a horizontal object. The angle between the legs when squatting can vary from zero to widely splayed out, flexibility permitting. Another variable may be the degree of forward tilt of the upper body from the hips. Squatting may be either full or partial. Crouching is usually considered to be synonymous with squatting. It is common to squat with one leg and kneel with the other leg. One or both heels may be up when squatting. Young children often instinctively squat. Among Chinese, Southeast Asian and Eastern European adults, squatting often takes the place of sitting or standing. Etymology Squatting comes from the Old French ''esquatir/escatir'', meaning to "compress/press down". The weight-lifting sense of squatting is from 1954.Harper, D. (n.d.). Etymol ...

Quadriceps
The quadriceps femoris muscle (, also called the quadriceps extensor, quadriceps or quads) is a large muscle group that includes the four prevailing muscles on the front of the thigh. It is the sole extensor muscle of the knee, forming a large fleshy mass which covers the front and sides of the femur. The name derives . Structure Parts The quadriceps femoris muscle is subdivided into four separate muscles (the 'heads'), with the first superficial to the other three over the femur (from the trochanters to the condyles): *The rectus femoris muscle occupies the middle of the thigh, covering most of the other three quadriceps muscles. It originates on the ilium. It is named for its straight course. *The vastus lateralis muscle is on the ''lateral side'' of the femur (i.e. on the outer side of the thigh). *The vastus medialis muscle is on the ''medial side'' of the femur (i.e. on the inner part thigh). *The vastus intermedius muscle lies between vastus lateralis and vastus mediali ...

Femur
The femur (; ), or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates. The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia (shinbone) and patella (kneecap), forming the knee joint. By most measures the two (left and right) femurs are the strongest bones of the body, and in humans, the largest and thickest. Structure The femur is the only bone in the upper leg. The two femurs converge medially toward the knees, where they articulate with the proximal ends of the tibiae. The angle of convergence of the femora is a major factor in determining the femoral-tibial angle. Human females have thicker pelvic bones, causing their femora to converge more than in males. In the condition ''genu valgum'' (knock knee) the femurs converge so much that the knees touch one another. The opposite extreme is ''genu varum'' (bow-leggedness). In the general populatio ...

Hip Joint
In vertebrate anatomy, hip (or "coxa"Latin ''coxa'' was used by Celsus in the sense "hip", but by Pliny the Elder in the sense "hip bone" (Diab, p 77) in medical terminology) refers to either an anatomical region or a joint. The hip region is located lateral and anterior to the gluteal region, inferior to the iliac crest, and overlying the greater trochanter of the femur, or "thigh bone". In adults, three of the bones of the pelvis have fused into the hip bone or acetabulum which forms part of the hip region. The hip joint, scientifically referred to as the acetabulofemoral joint (''art. coxae''), is the joint between the head of the femur and acetabulum of the pelvis and its primary function is to support the weight of the body in both static (e.g., standing) and dynamic (e.g., walking or running) postures. The hip joints have very important roles in retaining balance, and for maintaining the pelvic inclination angle. Pain of the hip may be the result of numerous cause ...

Hamstring
In human anatomy, a hamstring () is any one of the three posterior thigh muscles in between the hip and the knee (from medial to lateral: semimembranosus, semitendinosus and biceps femoris). The hamstrings are susceptible to injury. In quadrupeds, the hamstring is the single large tendon found behind the knee or comparable area. Criteria The common criteria of any hamstring muscles are: # Muscles should originate from ischial tuberosity. # Muscles should be inserted over the knee joint, in the tibia or in the fibula. # Muscles will be innervated by the tibial branch of the sciatic nerve. # Muscle will participate in flexion of the knee joint and extension of the hip joint. Those muscles which fulfill all of the four criteria are called true hamstrings. The adductor magnus reaches only up to the adductor tubercle of the femur, but it is included amongst the hamstrings because the tibial collateral ligament of the knee joint morphologically is the degenerated tendon of this muscl ...

Trapezius
The trapezius is a large paired trapezoid-shaped surface muscle that extends longitudinally from the occipital bone to the lower thoracic vertebrae of the spine and laterally to the spine of the scapula. It moves the scapula and supports the arm. The trapezius has three functional parts: an upper (descending) part which supports the weight of the arm; a middle region (transverse), which retracts the scapula; and a lower (ascending) part which medially rotates and depresses the scapula. Name and history The trapezius muscle resembles a trapezium, also known as a trapezoid, or diamond-shaped quadrilateral. The word "spinotrapezius" refers to the human trapezius, although it is not commonly used in modern texts. In other mammals, it refers to a portion of the analogous muscle. Similarly, the term "tri-axle back plate" was historically used to describe the trapezius muscle. Structure The ''superior'' or ''upper'' (or descending) fibers of the trapezius originate from the sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kettlebell
In weight training, a kettlebell is a cast-iron or cast-steel ball with a handle attached to the top (resembling a cannonball with a handle). It is used to perform many types of exercises, including ballistic exercises that combine cardiovascular, strength and flexibility training. Kettlebells are the primary equipment used in the weight-lifting sport of kettlebell lifting. History The Russian ''girya'' (, plural ) was a type of metal weight, primarily used to weigh crops in the 18th century. The use of such weights by circus strongmen is recorded for the 19th century. They began to be used for recreational and competition strength athletics in Russia and Europe in the late 19th century. The birth of competitive kettlebell lifting or ''girevoy sport'' (гиревой спорт) is dated to 1885, with the founding of the "Circle for Amateur Athletics" (Кружок любителей атлетики). Russian are traditionally measured in weight by ''pood'', cor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dumbbell
The dumbbell, a type of free weight, is a piece of equipment used in weight training. It can be used individually or in pairs, with one in each hand. History The forerunner of the dumbbell, halteres, were used in ancient Greece as lifting weights and also as weights in the ancient Greek version of the long jump. A kind of dumbbell was also used in India for more than a millennium, shaped like a club – so it was named Indian club. The design of the "Nal", as the equipment was referred to, can be seen as a halfway point between a barbell and a dumbbell. It was generally used in pairs, in workouts by wrestlers, bodybuilders, sports players, and others wishing to increase strength and muscle size. Etymology The term "dumbbell" or "dumb bell" originated in late Stuart England. In 1711 the poet Joseph Addison mentioned exercising with a "dumb bell" in an essay published in ''The Spectator''. Although Addison elsewhere in the same publication describes having used equipment sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbell
A barbell is a piece of exercise equipment used in weight training, bodybuilding, weightlifting, powerlifting and strongman, consisting of a long bar, usually with weights attached at each end. Barbells range in length from to above , although bars longer than are used primarily by powerlifters and are not commonplace. The central portion of the bar varies in diameter from 25 millimetres (0.98 in) to 50 millimetres (1.96 in) (e.g., Apollon's Axle), and is often engraved with a knurled crosshatch pattern to help lifters maintain a solid grip. Weight plates slide onto the outer portions of the bar to increase or decrease the desired total weight. Collars are used to prevent plates from moving outward unevenly so that the lifter does not experience uneven force. The barbell is the longer version of the dumbbell that is used for free weight training and competitive sports, such as powerlifting, Olympic weight lifting, and CrossFit. Many exercises can be done using th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
