Effect of a 6-week yoga intervention on swing mechanics during the golf swing:a feasibility study

Recent evidence suggests that participating in physical conditioning programmes can improve golf performance, however, the effectiveness of a yoga intervention has yet to be investigated. The aim of the current study was to investigate the effectiveness of a six-week yoga intervention on golf swing mechanics. Ten male golfers participated in the laboratory-based-study. Golf swing mechanics were collected from two testing sessions, before and after the six-week yoga intervention, using the Vicon motion capture system. Following the six-week yoga intervention, significant changes were observed between the yoga and control group in X-Factor (P ≤ 0.05) and a medium effect (d ≥ 0.50) observed. No significant changes (P > 0.05) and no effect (d < 0.20) were observed in the X-Factor stretch. Significant changes (P ≤ 0.05) and a medium effect (d > 0.50) were observed for the pelvis rotations following the yoga intervention, however, no differences were observed in torso rotations or hand velocities (P > 0.05). The findings of this feasibility study suggest that yoga may be a promising intervention in helping to improve golf swing mechanics, however, future research is required to confirm the effect of the use of yoga during the golf swing due to the sample size

Analysis of the X-Factor and X-Factor stretch during the completion of a golf practice session in low-handicap golfers

The X-Factor and X-Factor stretch have been positively correlated with golf long game performance. The aim of this study was to compare the X-Factor, X-Factor stretch and long game performance variables pre and following a golf practice session. A group of male golfers (n = 15, handicap = 3.3 ± 1.7) participated in the laboratory-based-study. Movement and performance variables were collected from five golf swings performed pre and following a golf practice session using a motion capture system and launch monitor respectively. Following the practice session, significant increases were observed in the X-Factor (p = 0.00, d = 0.22) and the X-Factor stretch (p = 0.02, d = 0.25). Specifically, the X-Factor increased from 52.82 ± 5.64 ° to 54.06 ± 5.61 ° following the practice session. The X-Factor stretch increased from 1.54 ± 1.05 ° to 1.90 ± 1.41 ° following the practice session. Significant differences were displayed in club head velocity (p = 0.00, d = 0.35), ball velocity (p = 0.01, d = 0.21) and actual carry distance (p = 0.00, d = 0.29) following the practice session. These findings suggest that performing multiple golf shots is not detrimental in terms of muscular fatigue in the long game performance. In actual fact, the findings demonstrate that performing 100 golf shots increases the X-Factor, X-Factor stretch patterns and performance variables which, in turn, increases long game performance. These findings can help PGA golf Professionals improve teaching practices and formulation of golf programmes and warm-up sessions

Electromyographic analyses of the erector spinae muscles during golf swings using four different clubs

The purpose of this study was to compare the electromyography (EMG) patterns of the thoracic and lumbar regions of the erector spinae (ES) muscle during the golf swing whilst using four different golf clubs. Fifteen right-handed male golfers performed a total of twenty swings in random order using the driver, 4-iron, 7-iron and pitching-wedge. Surface EMG was recorded from the lead and trail sides of the thoracic and lumbar regions of the ES muscle (T8, L1 and L5 lateral to the spinous-process). Three-dimensional high-speed video analysis was used to identify the backswing, forward swing, acceleration, early and late follow-through phases of the golf swing. No significant differences in muscle-activation levels from the lead and trail sides of the thoracic and lumbar regions of the ES muscle were displayed between the driver, 4-iron, 7-iron and pitching-wedge (P > 0.05). The highest mean thoracic and lumbar ES muscle-activation levels were displayed in the forward swing (67–99% MVC) and acceleration (83–106% MVC) phases of the swing for all clubs tested. The findings from this study show that there were no significant statistical differences between the driver, 4-iron, 7-iron and pitching-wedge when examining muscle activity from the thoracic and lumbar regions of the ES muscle

Comparison of thoracic and lumbar erector spinae muscle activation before and after a golf practice session

Lower back pain is commonly associated with golfers. The study aimed: to determine whether thoracic- and lumbar-erector-spinae muscle display signs of muscular fatigue after completing a golf practice session, and to examine the effect of the completed practice session on club head speed, ball speed and absolute carry distance performance variables. Fourteen right-handed male golfers participated in the laboratory-based-study. Surface electromyography (EMG) data was collected from the lead and trail sides of the thoracic- and lumbar-erector-spinae muscle. Normalized root mean squared (RMS) EMG activation levels and performance variables for the golf swings were compared before and after the session. Fatigue was assessed using median frequency (MDF) and RMS during the maximum voluntary contraction (MVC) performed before and after the session. No significant differences were observed in RMS thoracic- and lumbar-erector-spinae muscle activation levels during the five phases of the golf swing and performance variables before and after the session (p > .05). Significant changes were displayed in MDF and RMS in the lead lower lumbar and all trail regions of the erector-spinae muscle when comparing the MVC performed before and after the session (p < .05). Fatigue was evident in the trail side of the erector-spinae muscle after the session

The effect of upper body sprint interval training on golf drive performance

BACKGROUND: Improving golf fitness is one way to improve club head velocity and subsequently golf performance. The purpose of the study was to investigate the effect of a three-week upper-body sprint training (SIT) program on power output and golf performance.METHODS: Eleven golfers (handicap: 5.5±2.8) completed the SIT intervention. This was a self-controlled experiment with three testing points (pre-control, post-control and post-intervention) where subjects completed a ballistic bench press, upper-body Wingate and golf testing session.RESULTS: Significant improvements were observed (13.3-15.5%) in peak and mean power production during the Wingate post-intervention in comparison to pre- and post-control time points (P&lt;0.05). This was replicated in peak power for the ballistic bench press for both peak power (P&lt;0.05), but significance for mean power was only observed between post-control and post-intervention (P&lt;0.05) (improvements of 6.1-8.5%). These improvements were not seen consistently in golf performance variables measured, with no significance identified for the 7-iron and significant improvements (P&lt;0.05) observed in Carry Distance (2.2%) and Ball Velocity (1.4%) between pre-control and post-intervention.CONCLUSIONS: Lack of golf performance improvements could be because of the natural variation in club-head velocity across sessions or the inability of subjects to utilise their power gains during the golf swing. Longer SIT interventions may be needed to observe improvements in golf performance.</p

Physical activity accrued whilst golf caddying

Golf caddies are involved in golf at all levels of the game; however, little research has considered the physical activity (PA) accrued working in this profession. Importantly, the PA from playing golf can improve aspects of health; therefore, caddying may provide a PA that elicits similar benefits. This study, therefore, assessed the PA accrued whilst golf caddying. Eleven male caddies wore a PA monitor for 7-days and recorded time spent caddying while walking the 18-hole course at Carnoustie Golf Links, Scotland. Per day, caddies spent 224 minutes (58%) of their time caddying in light-intensity PA and 115 minutes (30%) of their time caddying in moderate-to-vigorous PA, accumulating 15480±4089 steps. Caddying accumulates enough moderate-to-vigorous PA across a week to exceed current PA guidelines, and the step count accrued is classified as highly active. Caddying can provide PA that has the potential to provide health benefits

OMEGA-3 SUPPLEMENTATION ON MUSCLE ACTIVATION PATTERNS OF THE KNEE DURING HIGH-RISK MOVEMENTS FOR ACL RUPTURES

The purpose of this study was to evaluate the role of omega-3 supplementation on fatigue and neuromuscular activation patterns of the lower extremity during a drop vertical jump (DVJ) and cutting maneuver. Seventeen female soccer players were allocated to a placebo (n=7) or omega-3 (n=10) (2.4g/day) group and were assessed before and after an 8-week period. EMG of the vastus lateralis (VL) and biceps femoris (BF) was evaluated during a DVJ and cutting maneuver prior to, and immediately following, a sport specific fatigue protocol. A 2x4 RM ANOVA revealed statistically significant (p≤0.05) increases in VL activation 100ms before initial contact (IC) during each movement assessed, and 50ms before IC during the DVJ on both limbs in the placebo group following the intervention. A significant increase in VL activation in the non-fatigued state 50ms before IC was reported in the omega-3 group during the DVJ on the dominant limb, following the intervention. Subtle changes in group means, in the fatigued cutting maneuver on the non-dominant limb, indicate a potentially beneficial adaptation in percent activation (Pre: 31±5% Post: 42±12%) and rate of activation (Pre: 106±60ms, post 30±10ms) for BF activity during weight acceptance in the omega-3 group. In conclusion, omega-3 supplementation increased activation of the VL 50ms before IC during the DVJ on the non-dominant limb in the fatigued state, post-intervention; but had no further statistically significant impact on muscle activity or rate of activation, following the 8-week period

Positive relationships between golf performance variables and upper body power capabilities

The importance of lower body and trunk strength and power, as well as upper body strength in golf is well documented, however the relationship between upper body power and golf performance has yet to be determined. Therefore, the purpose of the study was to investigate the relationships between golf performance and upper body power. Thirteen golfers (mean ± SD: age: 30 ± 7 years and handicap: 6.1 ± 4.9) participated in the study. Club head velocity (CHV) and ball velocity were measured during the golf test. In order to assess upper body power, subjects completed a ballistic bench press and upper body Wingate test. Pearson product-moment correlations were used to assess the relationships between golf performance and upper body power. The results demonstrated that there were strong relationships between ballistic bench press and CHV and ball velocity when using the driver (r &gt; 0.6 - 0.7), and moderate to strong relationships (r &gt; 0.4 - 0.6) when using the 7-iron. Strong relationships were found between the upper body Wingate test and CHV and ball velocity (r &gt; 0.5 - 0.8) when using the driver and 7-iron. As a results of the findings, strength and conditioning coaches may use both the ballistic bench press test and the Wingate test as a primary assessment to measure the effectiveness of upper body training interventions with the aim of improving golf performance. Although, when performing the golf swings at higher velocities (i.e. with the driver), the ballistic bench press may be a more beneficial

Commercial golf glove effects on golf performance and forearm muscle activity

The study aimed to determine whether or not commercial golf gloves influence performance variables and forearm muscle activity during golf play. Fifteen golfers participated in the laboratory based study, each performing 8 golf swings with a Driver and 7-iron whilst wearing a glove and 8 without wearing the glove. Club head speed, ball speed and absolute carry distance performance variables were calculated. Surface electromyography was recorded from the flexor digitorum superficialis and extensor carpi radialis brevis on both forearm muscles. Club head speed, ball speed and absolute carry distance was significantly higher when using the Driver with the glove in comparison to the Driver without the glove (p &lt; 0.05). No significant differences were evident when using the 7-iron and no significant differences were displayed in muscle activity in either of the conditions. Findings from this study suggest that driving performance is improved when wearing a glove
