A new device for evaluating distance and directional performance of golf putters. |
Nilsson J, Karlsen J. |
The purpose of this study was to construct and evaluate the reliability of an apparatus for testing golf putters with respect to distance and direction deviation at different impact points on the clubface. An apparatus was constructed based on the pendulum principle that allowed putter golf clubs to swing at different speeds. The mean speed of the club head before ball impact, and of the ball after impact, was calculated from time measurements with photocells. A pin profile rig was used to determine the directional deviation of the golf ball. Three different putters were used in the study, two that are commercially available (toe-heel weighted and mallet types) and one specially made (wing-type) putter. The points of impact were the sweet spot (as indicated by the manufacturer's aim line), and 1, 2 and 3 cm to the left and right of the sweet spot. Calculation of club head speed before impact, and of ball speed after impact (proportional to distance), showed errors < or = 0.5% of interval duration. The variability in ball impacts was tested by measuring time and direction deviations during 50 impacts on the same ball. The mean duration (+/- s) after ball impact in the test interval |

A systematic review of strength and conditioning programmes designed to improve fitness characteristics in golfers. |
Smith CJ, Callister R, Lubans DR. |
It has been suggested that conditioning programmes have the potential to improve golf performance through fitness adaptations. The primary aim of this systematic review was to evaluate the effectiveness of conditioning programmes on measures of golf-related fitness and golf performance. Four electronic library databases were searched and the quality of the studies was assessed using criteria adapted from the Consolidated Standard of Reporting Trials statement. Thirteen studies satisfied our criteria for inclusion. Nine studies involved middle-aged to older male recreational golfers and four studies used younger more skilled golfers. Conditioning programmes involved the use of machine weights, free weights, medicine balls, and elastic bands, and most studies included a flexibility component. Most studies assessed changes in fitness characteristics and generally resulted in improvements. All but two of the studies assessed changes in club head speed and reported increases. The findings from this review suggest that strength and conditioning programmes can have a positive effect on the golf swing and fitness characteristics of golfers. The majority of studies in this review evaluated |

A three-dimensional examination of the planar nature of the golf swing. |
Coleman SG, Rankin AJ. |
Previous planar models of the downswing in golf have suggested that upper limb segments (left shoulder girdle and left arm) move in a consistent fixed plane and that the clubhead also moves only in this plane. This study sought to examine these assumptions. Three-dimensional kinematic analysis of seven right-handed golfers of various abilities (handicap 0- 15) was used to define a plane (named the left-arm plane) containing the 7th cervical vertebra, left shoulder and left wrist. We found that the angles of this plane to the reference horizontal z axis and target line axis (parallel to the reference x axis) were not consistent. The angle to the horizontal z axis varied from a mean of 133 degrees (s = 1 degrees) at the start of the downswing to 102 degrees (s = 4 degrees) at impact, suggesting a "steepening" of the left-arm plane. The angle of the plane to the target line changed from - 9 degrees (s = 16 degrees) to 5 degrees (s = 15 degrees) during the same period, showing anticlockwise (from above) rotation, although there was large inter-individual variation. The distance of the clubhead from the left-arm plane was 0.019 m (s = 0.280 m) at the start at the downswing and 0.291 m ( |

Abdominal muscle activation of elite male golfers with chronic low back pain. |
Horton JF, Lindsay DM, Macintosh BR. |
The purpose of this study was twofold: 1) to determine whether elite male golfers with chronic low back pain (CLBP) exhibit different abdominal muscle activity patterns during the golf swing than asymptomatic control (AC) golfers and 2) to determine whether elite male golfers with CLBP experience greater fatigue in the abdominal muscles than AC golfers after a typical practice session. |

Acromioclavicular joint injury in competitive golfers. |
Mallon WJ, Colosimo AJ. |
We reviewed a series of professional and competitive low-handicap golfers with shoulder pain. All but one player (34/35) had pain in the left shoulder. A high incidence of problems (53%) related to the acromioclavicular joint was noted in these golfers with left shoulder pain. With proper treatment all but one (17/18 [94%]) of the golfers with acromioclavicular joint problems was able to return to competitive golf. By studying the mechanics of the golf swing, a possible mechanism for this high incidence of acromioclavicular joint problems is given. |

Acute bucket-handle tear of the medial meniscus in a golfer. |
Hame SL, Kohler-Ekstrand C, Ghiselli G. |
This is the first case report of an acute bucket-handle tear in an amateur golfer. The injury occurred during the follow-through phase of the golf swing. The rate of incidence of knee injuries in golfers is only 10%. There is a difference in the injury pattern between amateur and professional golfers; amateurs are more likely to sustain injuries related to poor swing technique. Professional golfers, on the other hand, report more injuries related to overuse. Although forces in the knee are relatively minor in this sport, acute injuries can happen when poor technique is used. |

Acute effects of passive static stretching during warm-up on driver clubhead speed, distance, accuracy, and consistent ball contact in young male competitive golfers. |
Gergley JC. |
This investigation was conducted to determine the effect of 2 different warm-up treatments on clubhead speed, distance, accuracy, and consistent ball contact in 15 young male competitive golfers. Two supervised warm-up treatments, an active dynamic warm-up with golf clubs (AD) and a 20-minute total-body passive static stretching routine plus an identical AD warm-up (SS), were applied before each performance testing session using a counterbalanced design on nonconsecutive days. Immediately after each warm-up treatment, subjects were instructed to hit 10 full-swing golf shots with their driver after their normal preshot routine, with 1 minute of rest between trials. Significant (p < 0.05) decreases in clubhead speed (-4.19%), distance (-5.62%), accuracy (-31.04%), and consistent ball contact (-16.34%) were observed. Theoretical explanations for this acute decrease in performance include a more compliant muscle tendon unit, decreased neuromuscular reflex sensitivity, and neural inhibition attributable to the SS treatment. The results of this inquiry strongly suggest that a total-body passive static stretching routine should be avoided before practice or competition in favor of a gradu |

Age-Related Differences in the Rhythmic Structure of the Golf Swing. |
Kim TH, Jagacinski RJ, Lavender SA. |
ABSTRACT Participants were 20 younger golfers (M age = 19.8 years, SD = 1.84 years) and 20 older golfers (M age = 63.0 years, SD = 2.55 years) who attempted 40- and 80-yard eight-iron shots requiring an adjustment of their force and timing. No age-related differences were found in the tempo or speed of the shot; however, there were differences in the rhythmic relationship between the clubhead force and the weight shift. Whereas younger golfers primarily exhibited a 3 versus 2 polyrhythmic pattern between the peak forces of the clubhead and weight shift, older golfers primarily exhibited a simpler 3 versus 3 rhythmic force pattern by adding a forward weight shift at the beginning of the shot. Additionally, older golfers exhibited less independence between the timing of the clubhead force and weight shift, which indicated greater use of a single integrated coordinative unit rather than 2 units. These findings are interpreted as compensations for age-related slowing and increased temporal variability that help to preserve tempo at a speed comparable to younger adults. |

An eight-week golf-specific exercise program improves physical characteristics, swing mechanics, and golf performance in recreational golfers. |
Lephart SM, Smoliga JM, Myers JB, Sell TC, Tsai YS. |
The purpose of this study was to determine the effects of an 8-week golf-specific exercise program on physical characteristics, swing mechanics, and golf performance. Fifteen trained male golfers (47.2 +/- 11.4 years, 178.8 +/- 5.8 cm, 86.7 +/- 9.0 kg, and 12.1 +/- 6.4 U.S. Golf Association handicap) were recruited. Trained golfers was defined operationally as golfers who play a round of golf at least 2-3 times per week and practice at the driving range at least 2-3 times per week during the regular golf season. Subjects performed a golf-specific conditioning program 3-4 times per week for 8 weeks during the off-season in order to enhance physical characteristics. Pre- and posttraining testing of participants included assessments of strength (torso, shoulder, and hip), flexibility, balance, swing mechanics, and golf performance. Following training, torso rotational strength and hip abduction strength were improved significantly (p < 0.05). Torso, shoulder, and hip flexibility improved significantly in all flexibility measurements taken (p < 0.05). Balance was improved significantly in 3 of 12 measurements, with the remainder of the variables demonstrating a nonsignificant trend for |

An examination of the planar nature of golf club motion in the swings of experienced players. |
Coleman S, Anderson D. |
The golf swing has been modelled as a planar movement, but recent findings suggest that the upper limbs and golf club do not move in a single plane. However, the idea that the club alone can be swung in a single inclined plane has not been investigated mathematically. The aims of this study were to determine whether a single plane could be fitted to club motion, and if this plane varied for different clubs. Ten golfers (handicap 1-5) performed repeated, consistent swings with three clubs (driver, 5-iron, and pitching wedge). The motion of each club during the downswing was fitted to a single plane. The fit of the plane varied between golfers and clubs (r(2) = 0.871-0.995, root mean square residual = 44.9-166.2 mm). Mean angles of the plane to the reference horizontal Z axis (driver: 125.5 degrees , s = 3.0; 5-iron: 117.1 degrees , s = 3.0; wedge: 113.6 degrees , s = 2.7) and target line axis (driver: -7.8 degrees , s = 5.9; 5-iron: -4.9 degrees , s = 5.7; wedge: -5.9 degrees , s = 6.0) were significantly (P < 0.05) different. Further analysis revealed a single plane was more appropriate for some participants than others, but that it might be neither desirable nor possible in some c |

Analysis of 3D kinematics concerning three different clubs in golf swing. |
Egret CI, Vincent O, Weber J, Dujardin FH, Chollet D. |
Although many professionals have produced books or videotapes which offer a novel approach to the game, a review of the scientific literature reports limited research evaluating the actual biomechanics of the golf swing in comparison with other sports. The aim of this study was to investigate the influence of kinematic pattern in golf swing using three different clubs: driver, five-iron, pitching-wedge. These three golf clubs have been chosen for their available range of ball flight. The measures of kinematic data during swing were established with the optoelectronic system VICON (Oxford's Metrics, Oxford, UK) with five cameras operating at 50 frames per second. Clubhead speed was measured using a swing made detector (Bell-Tronics, Ltd, Covington, USA). Seven right-handed male golfers with a high level of skill participated in the study. The results showed that there was an identical timing (movement time and proportion for each phase of the swing) between the three clubs tested, but the kinematics and the clubhead speed were different depending on the three different clubs used. |

Analysis of the 5 iron golf swing when hitting for maximum distance. |
Healy A, Moran KA, Dickson J, Hurley C, Smeaton AF, O'Connor NE, Kelly P, Haahr M, Chockalingam N. |
Most previous research on golf swing mechanics has focused on the driver club. The aim of this study was to identify the kinematic factors that contribute to greater hitting distance when using the 5 iron club. Three-dimensional marker coordinate data were collected (250 Hz) to calculate joint kinematics at eight key swing events, while a swing analyser measured club swing and ball launch characteristics. Thirty male participants were assigned to one of two groups, based on their ball launch speed (high: 52.9 ± 2.1 m · s(-1); low: 39.9 ± 5.2 m · s(-1)). Statistical analyses were used to identify variables that differed significantly between the two groups. Results showed significant differences were evident between the two groups for club face impact point and a number of joint angles and angular velocities, with greater shoulder flexion and less left shoulder internal rotation in the backswing, greater extension angular velocity in both shoulders at early downswing, greater left shoulder adduction angular velocity at ball contact, greater hip joint movement and X Factor angle during the downswing, and greater left elbow extension early in the downswing appearing to contribute to g |

Are anthropometric, flexibility, muscular strength, and endurance variables related to clubhead velocity in low- and high-handicap golfers? |
Keogh JW, Marnewick MC, Maulder PS, Nortje JP, Hume PA, Bradshaw EJ. |
The present study assessed the anthropometric profile (International Society for the Advancement of Kinanthropometry protocol), flexibility, muscular strength, and endurance of 20 male golfers. These data were collected in order to determine: a) the relationship between these kinanthropometric measures and clubhead velocity; and b) if these measures could distinguish low-handicap (LHG) and high-handicap (HHG) golfers. Ten LHG (handicap of 0.3 +/- 0.5) and 10 HHG (handicap of 20.3 +/- 2.4) performed 10 swings for maximum velocity and accuracy with their own 5-iron golf club at a wall-mounted target. LHG hit the target significantly more (115%) and had a 12% faster clubhead velocity than HHG (p < 0.01). The LHG also had significantly (28%) greater golf swing-specific cable woodchop (GSCWC) strength (p < 0.01) and tendencies for greater (30%) bench press strength and longer (5%) upper am and total arm (4%) length and less (24%) right hip internal rotation than HHG (0.01 < p < 0.05). GSCWC strength was significantly correlated to clubhead velocity (p < 0.01), with bench press and hack squat strength as well as upper arm and total arm length also approaching significance (0.01 < p < 0.0 |

Back pain in golf. |
Hosea TM, Gatt CJ Jr. |
Although golfing is generally considered a begin activity, lower back pain is endemic among golfers. The golf swing subjects the lumbar spine to rapid, intense loads, more frequently in amateurs than in professionals. These loads predispose the golfing population to muscle strains, lumbar disc disease, spondylolysis, and facet joint arthropathy. It is imperative for all golfers to warm up properly, develop good swing mechanics, and participate in a lower back conditioning program off the golf course. |
