The golf swing is the action by which players hit the ball in the sport of golf. The golf swing is a complex motion involving the whole body; the technicalities of the swing are known as golf stroke mechanics.
There are differing opinions on what constitutes a "good" golf swing. [1] In Work and Power Analysis of the Golf Swing, Nesbit and Serrano suggest the golf swing has been studied by scientists and mathematicians who have developed various equations to help explain the complexity of the swing. It is generally agreed that a successful and consistent golf swing requires precise timing and mechanics, from the grip and position of one's fingers, to the position and movement of the feet. [2] At any moment of the swing, whether back-swing, downswing, or upswing, something can go wrong that will throw off the whole body and result in a mishit. The entire swing motion should move on a plane in a fluid manner. The plane can be characterized as horizontal or vertical. [3]
The goal of the golf swing is to direct kinetic energy into the club head so when it comes into contact with the ball, the energy will transfer to the ball, sending it into flight. [2] Before a swing is taken golfers first adopt their stance. This is usually a partial crouch because it allows for a more effective range of movement whilst also preloading the muscles. The stance is critical in making sure that the golfer has a low center of gravity in order that they may remain balanced throughout the swing path. The swing starts with the arms moving back in a straight line. When the club head reaches the level of the hip, two things happen: there is a stern wrist cock that acts as a hinge along with the left knee (for a right-handed swing), building up its torque by moving into the same line as the belly button before the start of the upswing. [2] As the swing continues to the top of the backswing (again for right-handed golf swing), the golfer's left arm should be perfectly straight and his right arm should be hinged at the elbow. [1]
The downswing begins with the hips and the lower body rather than the arms and upper body, with emphasis on the wrist cock. As the golfer's hips shift towards the target and begin rotate, the right elbow will drop straight down, hugging the right side of the golfer's torso. [4] As the right elbow drops, the wrists begin to snap through from the wrist cock in the backswing. A solid extension of the arms and good transfer of body should put the golfer leaning up on his right toe, balanced, with the golf club resting on the back of the golfers neck. [1] Importantly, all of the movements occur with precise timing, while the head remains completely still with eyes focused on the ball throughout the entire swing. [1]
A golf stroke uses muscles in the core (especially erector spinae muscles and latissimus dorsi muscle when turning), hamstrings, shoulders and wrists. [5] Stronger muscles in the wrists can prevent the wrists from being twisted throughout the swing, while stronger shoulders increase the turning force. Weak wrists can also deliver the impact to elbows and even the neck and lead to injury of both. (When a muscle contracts, it pulls equally from both ends and, in order to have movement at only one end of the muscle, other muscles must come into play to stabilize the bone to which the other end of the muscle is attached.) Golf is a unilateral exercise that can break body balances, requiring exercise to keep the balance in muscles. One recommended exercise is free weight training, which is not reliant on machines to stimulate and balance the fine muscles. [6]
Timing is the most critical element of the golf swing because it connects all of the different moving parts of the body into one motion. The golf swing follows a double pendulum model, where the arms and shoulders become the first pendulum and movements along the hands, grip, and shaft form the second. Both of these interlocking pendulum movements must be timed correctly in order to reach maximum club head speed. [10]
"On the backswing aka the first part of the swing, the order of movement goes like this: hands, arms, shoulders, hips" (Ben Hogan: Five Lessons: the Modern Fundamentals). The downswing (the second part of the swing) is initiated by the shifting and unwinding of the hips. Then the shoulders and arms follow. [11]
The golf swing is capable of producing great force, though it takes practice to be able to effectively utilize it in a productive manner. [1] Most amateur golfers try to get as much power as possible, and try to hit the ball as far as possible, but this is not an appropriate approach for an amateur. [2] The power of the golf swing is not unlocked by muscle or by fastest club head speed, but by the precise timing and mechanics of a motion that has to be put together in harmony. However, more power in the golf swing can be attributed to the development of these lower limb muscles: tibialis anterior, peroneus longus, gastrocnemius medialis, gastrocnemius lateralis, biceps femoris, semitendinosus, gluteus maximus, vastus medialis, rectus femoris and vastus lateralis. With more power, comes the necessity for more control over the body that a golfer must have to control the motions of the swing. "Strength and inertial variations seem more likely than size to account for long and short hitting". [4]
The chip is a type of shot generally used from short range around the green usually under 40 yards. Although any club may be used, and there are specialist chipping clubs (or chippers) available, a short iron or wedge is most common.
The goal of the chip is to land the ball safely on the green and let it roll out towards the hole.
A "pitch shot" is a shot played with a high lofted club, a lob wedge, sand wedge, gap wedge, or pitching wedge, with lofts ranging from 49° to 62°. These high lofted clubs are designed to hit the ball high from short distances, usually from 30–70 yards (30–60 m) and closer.
The putt is used for putting the ball in the hole or closer to the hole (as in lagging) from the green or the fringe of the green. It can also be done from off the fringe and from in the fairway, especially on Bermuda Grass. The putter is used for the putt. The golfer adjusts their putt to fit the circumstances of the play such as distance to the hole and slope of the green.
The face of the club starts square to the target line. The club goes straight back and straight through along the same path like a pendulum. One strategy is to aim the ball 10% past the hole. Another is to look at the hole for long putts instead of the ball.
A sand wedge, or sand iron, is a type of golf club, an open-faced wedge primarily designed for getting out of sand bunkers. It has the widest sole of any wedge, which provides the greatest amount of bounce, allowing the club head to glide through sand and avoid digging in. After Gene Sarazen had success in 1932 with a new club that he had invented for sand play, its popularity quickly grew. The club can be advantageous in other soft lies—such as thick rough, soggy ground, or mud—and is also used from firmer grass lies for lobs or chips.
William Ben Hogan was an American professional golfer who is generally considered to be one of the greatest players in the history of the game. He is notable for his profound influence on golf swing theory, inventing the idea of practicing golf and his ball-striking ability.
A golf course is the grounds on which the sport of golf is played. It consists of a series of holes, each consisting of a tee box, a fairway, the rough and other hazards, and a green with a cylindrical hole in the ground, known as a "cup". The cup holds a flagstick, known as a "pin". A standard round of golf consists of 18 holes, and as such most courses contain 18 distinct holes; however, there are many 9-hole courses and some that have holes with shared fairways or greens. There are also courses with a non-standard number of holes, such as 12 or 14.
A golf club is a club used to hit a golf ball in a game of golf. Each club is composed of a shaft with a grip and a club head. Woods are mainly used for long-distance fairway or tee shots; irons, the most versatile class, are used for a variety of shots; hybrids that combine design elements of woods and irons are becoming increasingly popular; putters are used mainly on the green to roll the ball into the hole. A set of clubs is limited by the rules of golf to a maximum of 14 golf clubs, and while there are traditional combinations sold at retail as matched sets, players are free to use any combination of legal clubs.
A golf ball is a ball designed to be used in golf. Under the rules of golf, a golf ball has a mass no more than 1.620 oz (45.93 g), has a diameter not less than 1.680 inches (42.67 mm), and performs within specified velocity, distance, and symmetry limits. Like golf clubs, golf balls are subject to testing and approval by The R&A and the United States Golf Association, and those that do not conform with regulations may not be used in competitions (Rule 5–1).
The following is a glossary of the terminology currently used in the sport of golf. Where words in a sentence are also defined elsewhere in this article, they appear in italics. Old names for clubs can be found at Obsolete golf clubs.
In the sport of golf, a wedge is a subset of the iron family of golf clubs designed for special use situations. As a class, wedges have the highest lofts, the shortest shafts, and the heaviest clubheads of the irons. These features generally aid the player in making accurate short-distance "lob" shots, to get the ball onto the green or out of a hazard or other tricky spot. In addition, wedges are designed with modified soles that aid the player in moving the clubhead through soft lies, such as sand, mud, and thick grass, to extract a ball that is embedded or even buried. Wedges come in a variety of configurations, and are generally grouped into four categories: pitching wedges, sand wedges, gap/approach wedges and lob wedges.
In golf, a gap wedge, also known as an approach wedge, is a wedge used to hit a shot with higher and shorter trajectory than a pitching wedge and lower and longer trajectory than a sand wedge. The name derives from the club's design to fill the "gap" between sand and pitching wedges.
The shaft of a golf club is the long, tapered tube which connects the golfer's hands to the club head. While hundreds of different designs exist, the primary purpose of the golf shaft remains the same: to provide the player with a way to generate centrifugal force in order to effectively strike the ball. When properly gripped the player can hit the ball further and more accurately, whilst applying less force.
Golf equipment encompasses the various items that are used to play the sport of golf. Types of equipment include the golf ball, golf clubs, and devices that aid in the sport.
In the sport of golf, a penalty or penalty stroke is an additional stroke or strokes added to a player's score for an infraction of the rules. In match play, rather than adding strokes, the usual penalty is loss of the hole except for penalties assessed for relief from a hazard or a lost ball.
A wood is a type of club used in the sport of golf. Woods have longer shafts and larger, rounder heads than other club types, and are used to hit the ball longer distances than other types.
An iron is a type of club used in the sport of golf to propel the ball towards the hole. Irons typically have shorter shafts and smaller clubheads than woods, the head is made of solid iron or steel, and the head's primary feature is a large, flat, angled face, usually scored with grooves. Irons are used in a wide variety of situations, typically from the teeing ground on shorter holes, from the fairway or rough as the player approaches the green, and to extract the ball from hazards, such as bunkers or even shallow water hazards.
A hybrid is a type of club used in the sport of golf with a design borrowing from both irons and woods while differing from both. The name "hybrid" comes from genetics to denote a mixture of two different species with desirable characteristics of both, and the term here has been generalized, combining the familiar swing mechanics of an iron with the more forgiving nature and better distance of a wood.
A putter is a club used in the sport of golf to make relatively short and low-speed strokes with the intention of rolling the ball into the hole from a short distance away. It is differentiated from the other clubs by a clubhead with a very flat, low-profile, low-loft striking face, and by other features which are only allowed on putters, such as bent shafts, non-circular grips, and positional guides.
The 1985 U.S. Open was the 85th U.S. Open, held June 13–16 at the South Course of Oakland Hills Country Club in Bloomfield Hills, Michigan, a suburb northwest of Detroit. Andy North, the 1978 champion, won his second U.S. Open title by a stroke over runners-up Dave Barr, Chen Tze-chung, and Denis Watson.
Golf is a club-and-ball sport in which players use various clubs to hit a ball into a series of holes on a course in as few strokes as possible.
