Pull-down (exercise)
The pull-down exercise is a strength training exercise designed to develop the latissimus dorsi muscle. It performs the functions of downward rotation and depression of the scapulae combined with adduction and extension of the shoulder joint. The cable lat pull-down is done where the handle is moved via a cable pulley, as opposed to doing pull-downs on a leverage machine. Muscles The standard pull-down motion is a compound movement that requires dynamic work by muscles surrounding the three joints which move during the exercise. These are the elbow in conjunction with the glenohumeral and scapulothoracic joints in the shoulder girdle. Latissimus dorsi The latissimus dorsi performs extension and adduction of the arm directly to the spinal fascia. It bypasses the scapulae unlike other muscles which perform this function, so work performed by this muscle will not contribute to muscles that affect the scapulae. The lower sternal fibers of the pectoralis major also perform this role ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subscapularis
The subscapularis is a large triangular muscle which fills the subscapular fossa and inserts into the lesser tubercle of the humerus and the front of the capsule of the Glenohumeral joint, shoulder-joint. Structure The subscapularis is covered by a dense fascia which attaches to the scapula at the margins of the subscapularis' attachment (origin) on the scapula. The muscle's fibers pass laterally from its origin before coalescing into a tendon of insertion. The tendon intermingles with the Glenohumeral, glenohumeral (shoulder) joint capsule.

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 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 progressive overload, progressively increasing the force output of the muscles and uses a variety of exercises and types of :Weight training equipment, equipment. Strength training is primarily an anaerobic exercise, anaerobic activity, although circuit training also is a form of aerobic exercise. Strength training can increase Skeletal muscle, 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.

Standing Position
Anatomical terminology is a specialized system of terms used by anatomists, zoologists, and health professionals, such as doctors, surgeons, and pharmacists, to describe the structures and functions of the body. This terminology incorporates a range of unique terms, prefixes, and suffixes derived primarily from Ancient Greek and Latin. While these terms can be challenging for those unfamiliar with them, they provide a level of precision that reduces ambiguity and minimizes the risk of errors. Because anatomical terminology is not commonly used in everyday language, its meanings are less likely to evolve or be misinterpreted. For example, everyday language can lead to confusion in descriptions: the phrase "a scar above the wrist" could refer to a location several inches away from the hand, possibly on the forearm, or it could be at the base of the hand, either on the palm or dorsal (back) side. By using precise anatomical terms, such as "proximal," "distal," "palmar," or "do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supination
Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved. Anatomists and others use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing unique movements such as those of the hands, feet, and eyes. In general, motion is classified according to the anatomical plane it occurs in. ''Flexion'' and ''extension'' are examples of ''angular'' motions, in which two axes of a joint are brought closer together or moved further apart. ''Rotational'' motion may occur at other joints, for example the shoulder, and are described as ''internal'' or ''external''. Other terms, such as ''elevation'' and ''depression'', describe movement above or below the horizontal plane. Many anatomic ...

Weight Machine
A weight machine is an exercise machine used for weight training that uses gravity as the primary source of resistance and a combination of simple machines to convey that resistance to the person using the machine. Each of the simple machines (pulley, lever, wheel, incline) changes the mechanical advantage of the overall machine relative to the weight. Stack machines A ''stack machine''—also called a ''stack'' or ''rack''—has a set of rectangular plates that are pierced by a vertical bar which has holes drilled in it to accept a pin. Each of the plates has a channel on its underside (or a hole through the middle, as visible in the picture) that aligns with one of the holes. When the pin is inserted through the channel into the hole, all of the plates above the pin rest upon it, and are lifted when the bar rises. The plates below do not rise. This allows the same machine to provide several levels of resistance over the same range of motion with an adjustment th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joe Weider
Josef Weider (; November 29, 1919 – March 23, 2013) was a Canadian bodybuilder and entrepreneur who co-founded the International Federation of BodyBuilders (IFBB) alongside his brother Ben Weider. He was also the creator of Mr. Olympia, Ms. Olympia, and the Masters Olympia bodybuilding contests. He was the publisher of various bodybuilding and fitness-related magazines, most notably ''Muscle & Fitness'', ''Flex (magazine), Flex'', ''Men's Fitness,'' and ''Shape (magazine), Shape'', and the manufacturer of a line of fitness equipment and fitness supplements. In 2014, he was inducted into the International Sports Hall of Fame. Early life Weider was born in Montreal, Quebec, to Louis and Anna Weider, Jewish immigrants from Poland. Weider's unique accent displayed his old world roots, described by his son Eric as "somewhere between Yiddish, Canadian, old Polish...this Montreal kind of stew of accents." Weider began weight training in his teenage years into order to stand up to bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Closed Kinetic Chain Exercises
Closed kinetic chain exercises or closed chain exercises (CKC) are physical exercises performed where the hand (for arm movement) or foot (for leg movement) is fixed in space and cannot move. The extremity remains in constant contact with the immobile surface, usually the ground or the base of a machine. The opposite of CKC exercises are open kinetic chain exercises (OKC). Closed chain exercises are often compound movements, that generally incur compressive forces, while open-chain exercises are often isolation movements that promote more shearing forces. CKC exercises involve more than one muscle group and joint simultaneously rather than concentrating solely on one, as many OKC exercises do (single-joint movements), lending the former to more utilitarian and athletic activities. Properties These exercises are typically weight bearing exercises, where an exerciser uses one's own body weight and/ or external weight.

Open Kinetic Chain Exercises
Open chain exercises (OKE) are exercises that are performed where the hand or foot is free to move. The opposite of OKE are closed kinetic chain exercises (CKE). Both are effective for strengthening and rehabilitation objectives. Closed-chain exercises tend to offer more "functional" athletic benefits because of their ability to recruit more muscle groups and require additional skeletal stabilization. Properties Single-joint versions of these exercises are typically non-weight bearing, with the movement occurring at the hinge joints (elbow or knee). If there is any weight applied, it is often applied to the distal portion of the limb. Open chain exercises are postulated to be advantageous in rehabilitation settings because they can be easily manipulated to selectively target specific muscles, or specific heads of certain muscles, more effectively than their closed chain counterparts, at different phases of contraction.

Pull-up (exercise)
A pull-up is an upper-body strength exercise. The pull-up is a Closed kinetic chain exercises, closed-chain movement where the body is suspended by the hands, gripping a bar or other implement at a distance typically wider than shoulder-width, and pulled up. As this happens, the elbows flexion, flex and the shoulders adduction, adduct and extension (anatomy), extend to bring the elbows to the torso. Pull-ups build up several muscles of the upper body, including the Latissimus dorsi muscle, latissimus dorsi, trapezius, and biceps brachii. A pull-up may be performed with overhand (pronated), underhand (supinated)—sometimes referred to as a chin-up—neutral, or rotating hand position. Pull-ups are used by some organizations as a component of fitness tests, and as a conditioning activity for some sports. Movement Beginning by hanging from the bar, the body is pulled up vertically. From the top position, the participant lowers their body until the arms and shoulders are fully ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squatting Position
Squatting is a versatile List of human positions, posture where the weight of the body is on the feet but the knees and hips are bent. In contrast, sitting involves supporting the weight of the body on the ischial tuberosities of the pelvis, with the lower buttocks in contact with 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".Harper, D. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
