Evaluating the biomechanical and performance factors of the knee joint during golf swing can provide objective and quantitative information about improving the performance and development of efficient physical training, as the legs are important for achieving an efficient swing and maximum speed of the club head in golf. In the present study, kinematic movements of the knee joint were identified during the downswing by using 3-dimensional motion analysis, and isokinetic strength was measured with driver and 5-iron clubs in 15 professional (PRO) golfers and 10 amateur (AMA) golfers...

Human motor control is based on complex sensorimotor processes. Recent research has shown that neuromuscular activity of the craniomandibular system (CMS) might affect human motor control. In particular, improvements in postural stability and muscle strength have been observed as a result of voluntary jaw clenching. Potential benefits of jaw aligning appliances on muscle strength and golf performance have also been described. These reports are highly contradictory, however, and the oral motor task performed is often unclear...

There are many studies showing that physical training improves body composition including bone mineral density (BMD) in almost all subjects. However, the frequency-dependent effect of playing golf on body composition is still not clearly comprehended. Moreover, the effect of screen golf in relations with exercise-frequency on body composition and golf performance has not been documented. Forty year old men participated and were classified into 4 groups: Control group (n= 10), BMD1 group (n= 10) played screen golf less than 1 day per a week, BMD2-3 group (n= 10) played screen golf 2-3 days per a week, and BMD5 group (n= 10) played screen golf 5 days per week...

The purpose of this study was to determine the effects of a 36 session COREPOWER machine training intervention and those of a 36 session home-based core training intervention programme on golfers' physical fitness and sport specific performance. It was hypothesised that both modalities will improve on golf related fitness aspects. Subjects comprised of experienced golfers and were randomly divided into a machine group (M: n = 51) and a home group (H: n = 50). The following variables were measured both pre- and post-intervention: lower back flexibility (sit & reach), muscle endurance (sit-ups and push-ups), muscle strength (wall-squats and back dynamometer), cardio-respiratory fitness (3 minute step-test), balance (Biodex Balance System), club head speed and carry distance (Flightscope)...

This study examined the effect of anxiety states on the relationship between golf-putting distance and performance in an environment requiring high movement accuracy. Twenty-three amateur golfers attempted 15 putts at each of three putting distances, 1.25, 1.50, and 1.75m, under conditions characterized by both control demands and pressure. All attempts were recorded, and kinematic features were analyzed. Under conditions involving an audience and a monetary reward, the mean score on the State-Trait Anxiety Inventory Y-1 and the mean heart rate increased by 14 points and 11bpm, respectively...

BACKGROUND: The physical demands required of the body to execute a shot in golf are enormous. Current evidence suggests that warm-up involving static stretching is detrimental to immediate performance in golf as opposed to active dynamic stretching. However the effect of resistance exercises during warm-up before golf on immediate performance is unknown. Therefore, the purpose of this study was to assess the effects of three different warm-up programs on immediate golf performance. METHODS: Fifteen elite male golfers completed three different warm-up programs over three sessions on non-consecutive days...

Increased golf club head speed (CHS) has been shown to result in greater driving distances and is also correlated with golf handicap. The purpose of this study was to investigate the relationships between field-based measures of strength and power and golf CHS with a secondary aim to determine the reliability of the selected tests. A correlation design was used to assess the following variables: anthropometrics, squat jump (SJ) height and squat jump peak power (SJPP), unilateral countermovement jump (CMJ) heights (right leg countermovement jump and left leg countermovement jump [LLCMJ]), bilateral CMJ heights, countermovement jump peak power (CMJPP), and medicine ball seated throw (MBST) and medicine ball rotational throw (MBRT)...

In golf, an increase in club head speed (CHS) has been shown to increase driving distance and is correlated with handicap. The purpose of this study was to investigate the effect of a postactivation potentiation (PAP) intervention on CHS. A FlightScope launch monitor was used to record CHS in 16 golfers (aged 20.1 ± 3.24 years, handicap 5.8 ± 2.26) during 2 testing sessions that were separated by 1 hour, using a counterbalanced design. The mean CHS of 3 swings was recorded with (experimental) and without (control) 3 preceding countermovement jumps (CMJs)...

Jay Worobets, Darren Stefanyshyn
The role of shaft stiffness on the golf swing is not well understood. Studies in which golfers hit balls with clubs of varying shaft flex have reported changes in ball distance. The results of mathematical models suggest that shaft stiffness affects only the orientation of the clubhead at impact, not the speed of the clubhead, but there are no experimental results validating these findings. The purpose of this study was therefore to experimentally examine the influence of shaft stiffness on clubhead kinematics at ball impact...
