Excessive anterior and posterior pelvic tilts (PT) angles are associated with overuse injuries of the lower limbs and of the lumbo-pelvic-hip complex. There is a lack of evidence that correlates anterior and posterior PT angles with limited hip internal rotation (IR) and external rotation (ER), and hip muscles torque ratios. The purpose of this study was to examine the correlation between averaged anterior/posterior PT angle in standing position and hip IR and ER range of motion (ROM), hip adductors and abductors (Add/Abd) torque ratio, and hip flexors and extensors (Flexor/Extensor) torque ratio. Twenty-six healthy participants participated in this study, fifteen females (22.0 ± 2.8 yrs, 163.5 ± 7.5 cm, 65.9 ± 10.4 kg) and eleven males (22.0 ± 2.2 yrs, 178.5 ± 4.5 cm, 78.4 ± 8.7 kg). Hip muscle torques were collected with an isokinetic dynamometer, five trials at 30 degrees per second (deg· s(−1)) and at 60 deg· s(−1). The measurement of PT in standing natural position and hip IR and ER ROM in functional weight-bearing lunge position were recorded, using a 3D Motion Analysis System. There were no significant correlations between PT angle and hip IR and ER (p ≥ 0.05), no significant correlations between PT angle and hip Add/Abd torque ratio (p > 0.05), and no significant correlations between PT angle and hip Flexor/Extensor torque ratio (p > 0.05). The measurement of PT angle in standing natural position was not associated with hip IR and ER ROM and hip Add/Abd and Flexor/Extensor torque ratios, in healthy population.

Background: EMG equipment is used to measure muscular activity during sports movements. A methodological study is hence necessary to identify how this cumbersome equipment may hinder golfers in performing the golf swing. Methods: Measurements of kinematic data during swing were conducted using an optoelectronic system. Surface bipolar electrodes with integrated preamplifiers were used to monitor the myoelectric signals during golf swing. Six experienced right-handed male golfers performed six swings with electromyographic equipment fixed on their body and six swings without electromyographic equipment. Results: There was a significant effect in terms of shoulder joint rotation at maximal backswing (7.7%), in the right elbow flexion at the address (3.7%), at the top of the backswing (3.1%) and in the clubhead speed (6.7%). Conclusions: EMG equipment influences the kinematic pattern of the golf swing.

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.

Golf has become an increasingly popular sport, which is enjoyed by both men and women. This paper addresses the question what differences may exist between men and women golfers. The purpose of this study is to analyze the kinematic pattern of the golf swing in both men and women experienced golfers. Seven male and five female golfers participated in the study. The measurements of kinematic data during swing were obtained with the optoelectronic system VICON (Oxford's Metric, Oxford, UK) with five cameras operating at 50 frames per second. Clubhead speed was measured using a radar system (Bell-Tronics, Ltd, Covington, USA). A Mann-Whitney test (p = 0.05) showed that the women seem to produce a wide swing with larger hip and shoulder joint rotation angles at the top of the backswing. Men flexed their left knee more during the backswing, this may promote a greater weight transfer to the right side. Nevertheless, these two kinematic patterns showed no significant differences in the clubhead speed. Men probably used their increased knee flexion to compensate for their muscular and articular suppleness which is less than that of the women. The results of this study show that there is a specific swing for women.
