    Golf games have ranged from competing for the fewest strokes to team competitions. The Pro Long Drive World Championship uses a competition format in which players hit six balls in 2 minutes and 30 seconds and compete for the longest distance. The game requires appropriate ball control because wind conditions and directions always change. Athletic skills are also needed for control between three different trajectories (straight [S], draw [D], and fade [F]) and flying distance. Very few studies have been published on Long-driving Players (Holt and Holt, 2013), and there is little research on ball trajectory at speeds of approximately 200 mph, which is above the speed of PGA Tour players (Chris and Erik, 2022). This study aimed to clarify the characteristics of shot performance in world-class long-distance golf players, who were randomly instructed to hit three different shots in an indoor environment using ball trajectory and movement analysis.

    The performance of golfers is significantly affected by weather conditions during extended periods of outdoor play. Thornes (1977) highlighted this aspect in his article “The Effect of Weather on Sport,” noting the unequal interference experienced by golfers due to varying weather conditions. Additionally, Jowett and Phillips (2023) identified wet-bulb temperature and zonal wind speed as the most reliable predictors of mean scores in Masters tournaments over the past 40 years. Previous studies have explored the influence of wind, particularly on airborne shots, and its impact on distance and spin (Malik and Saha, 2021). However, little attention has been paid to the effect of wind on putting strokes on the green, estimated to contribute to approximately 40% of golf scores. Over the past decade, major cities in Japan, such as Tokyo, Osaka, and Fukuoka, have experienced an average wind speed if 2.7 m/s (Japan Meteorological Agency). Consequently, in this study, wind speeds of 2 and 4 m/s were chosen to evaluate differences in ball-stop positions under artificially generated wind speeds commonly encountered in typical golf play. The objective was to gather fundamental data that could serve as indicators for green reading under windy conditions.

    To excel on a golf course, players need to master swing skills in a certain direction. Right-handed swingers occasionally utilize left-handed swinging training to suppress excessive asymmetry in any given direction. However, there is no clarity regarding the fundamental shot data of dominant and non-dominant golf swings. Thus, to analyze the differences between dominant right-handed swings and non-dominant left-handed swings, this study investigated the differences in club head speed (CHS) between amateur golfers (AG) and professional golfers (PG).

    Patterns of body movements and golf club head movements are specific to an individual player. With the increasing reliability of Doppler radar launch monitors, it has now become possible to compare parameters related to club head movement at ball impact from a common evaluation. However, analysis to the prediction of golf scores in previous studies has often used independent variables such as money prize and distance, which was a regression analysis model that amateur golfers (AG) and skilled golfers (SG) could not utilize. Our study aims to establish a statistical model that can evaluate golfing performance by analyzing the relationship between club head movement data from 15 driver shots corresponding to one round’s worth and the golf scores of AG versus SG.

    Professional golfers are thought to train repetitively for the purpose of mastering a fixed swing style that they can rely upon regardless of changes in conditions when taking a stroke. However, there is no research found that shows that professional golfers actually aren't changing their swing according to the conditions in which the stroke is being taken. There is also no guarantee that they always self-consciously make minor adjustments to all swings to adapt to a change in conditions. It is also unclear how much influence a change in conditions, namely the perception of information has on a golf swing. In this study club head behavior near the point of impact in professional golfers’ strokes was compared in differing uphill and downhill conditions. The purpose of the study is to verify through scientific investigation of attack angle, dynamic loft, launch angle and club path, how perception of taking an uphill or downhill stroke influences swing factors. Methods: Subjects consisted of 52 Japanese male professional golfers who are A-grade members of the Professional Golfers Association of Japan. The study was conducted at Maoi Golf Resort Driving Range (Hokkaido, Japan). The driving range length was over 330m between the tees meaning there was no risk that a drive taken either direction would reach the opposite tee. Furthermore, there was a height difference of 30m between the tees. Tests were conducted facing both the uphill and downhill slopes. However, the place of the stroke was horizontally level with only the ground between the stroke and the target being uneven. The clubs used were each individual’s own driver. 3 uphill and 3 downhill strokes (6 strokes) were analyzed for data. Participants were only instructed which direction to hit the ball and to use their natural swing. No other instructions were given. Before taking the measured strokes the participants were allowed between 10 and 50 strokes as per their preference, as warming up. In order to avoid polarization due to protocol where possible, half the participants began with 3 uphill strokes followed by 3 downhill strokes and the other half began with 3 downhill strokes followed by 3 uphill strokes. After taking the first 3 strokes the participants were transported to the opposite end where they would take the final 3 strokes by a cart. This allowed the total testing time to be completed within 30mins. Trajectory measurement was conducted using TrackMan (TrackMan A/S, Denmark) with attack angle, dynamic loft, launch angle, and club path as the measurement criteria. Participants could visually check the ball trajectory but were not given any measurement feedback. Statistical analysis was carried out a paired t-test using software SPSS 24.0, IBM, JAPAN with significance set at < 5%. Results: Table 1 shows the uphill and downhill data obtained from TrackMan. Attack Angle, Dynamic Loft, Launch Angle, and Club Path in the uphill stroke were 3.32 ± 2.59deg, 16.16 ± 2.72deg, 16.16 ± 2.73deg, and -2.13 ± 2.42 respectively, which were all significantly larger than in the downhill stroke. Discussion: In this study we scientifically investigated how influence perception of the shot environment being either uphill or downhill has on swing factors. The results showed that there was a significant difference in all 4 measured criteria. Attack angle, Dynamic loft and Launch angle, which are all related to obtaining ball height, were all significantly shown to be trying to attain higher ball elevation in the uphill stroke compared to the downhill stroke. This result suggests that even though professional golfers consciously may be trying to use the same swing form in uphill and downhill conditions as they would in flat conditions, self-consciousness automatically adjusts the swing which in turn influences the swing factors. In this study we did not measure shot accuracy left and right of the target. Therefore, we do not know if the adjustment in form has a positive influence on ball direction. Also, we do not know if this swing adjustment is also more or less prominent in beginner and intermediate level golfers. Due to the measurements being taken outdoors, we were not able to take more precise movement data so further research is necessary.

    We theorized that the fine putting skill of professional golfers could only be assessed through comparison with novice golfers using a challenge to stop a ball on a putting target from a certain distance. Furthermore, we took into account that professional golfers have great experience putting with their dominant hand, so we compared this with putting ability in the non-dominant hand to investigate if the motor skill is transferred. The accumulated data was used as a performance indicator for distance and direction. The experiment was conducted with the hypothesis that professional golfers would have a high ability to accurately stop the ball on or near the target with their dominant hand stroke and also have a higher ability with their non-dominant hand stroke than novice golfers have with either their dominant or non-dominant hand stroke. Methods: Participants were 11 collegiate students (Novice group: NG) who had no experience in golf and 9 professional golfers (pro group: PG). All participants were right handed players. The small target (25 cm2 square box) was 2m from the putting position. Participants used a TRANSAM CNC MILLED putter (LYNKS, USA) head that can be used for both right and left-handed putting, and the same golf ball. Each side of putting was performed 15 times alternating each putt between sides making a total of 30 putts each trial. Only one trial was performed a day. The first trial started with putting from the right side and the second trial from the left side. Each following was started with putting from the opposite side of the preceding trial (first trial right to left and second trial left to right and so forth). All conditions were the same for each trial except for the alternation of which putting side was first. The participants completed 4 sessions (S1 to S4) of the putting trial in one week meaning that two trials started from the right side and two started from the left side. The far side was defined as a positive value, the near side a negative value, the right side a positive value, and the left side a negative value. After measuring the positive or negative distance we then converted it to absolute data as the sum of distance of the 15 putts (A: Total Distance Variability). The right and left distance was also calculated by the same formula (B: Total Directional Variability). The diagonal distance calculated from the distance of A and B to the target is defined as Total Linear Variability (C). Statistical analysis was performed using a paired t-test for the difference of right and left-handed putting in each group (NG and PG). Multi-fractional ANOVAs was used for a comparison among session (S1 to S4) values. A non-paired t-test was used for the difference of each group in the 3 types of distance variability (A to C). Results: Total Distance Variability (A) in PG was significantly less than NG from S1 to S4 in both putting sides. Total Directional Variability (B) in PG was significantly less from S2 to S4 in both putting sides. Total Linear Variability (C) in PG was also significantly less from S1 to S4 in both putting sides. Table 1 shows the variability of D1 and D2 in PG and NG in right and left-handed putts. The percentage of positive distance (D1) in PG in right-handed putts was the highest value (85.9%). On the other hand, the percentage of negative distance (D2) in PG right-handed putts was lowest (14.1%). Discussion The results showed that the Total Distance Variability in PG was significantly smaller than NG, meaning PG possess high motor skill ability. Furthermore, distance data showed that when data was analyzed when separated into over (further than the target) and short (not reaching the target) data, the distance of the right-handed putts of PG were significantly over compared to NG, and also significantly over compared to left-handed putts in PG. In right-handed putts of PG 85.9% were over the target and that percentage didn't significantly change over the 4 sessions. In NG 54.7% of putts finished over the target and 45.3% short of the target. This shows that in PG variability in distance to the target is small but that PG tended to over-shoot the target even when attempting to accurately stop the ball on the target. This means that due to experience gained from many hours of practice, PG have a strong perceptive bias that placing the ball behind the target is important for attaining consistent direction. In this study, it is believed that such a result was due to the trial being conducted in a low-pressure environment, and we have labeled this strong perceptive bias as "Golfers Bias". However, this bias was not apparent in the non-dominant hand and it was made clear there was no change across the 4 trial sessions. Practical Application/ Clinical Relevance: When putting from a distance of approximately 2m, it is thought that golfers do not contemplate how hard they should strike the ball with the aim for it to stop at a particular distance, but rather are repeating an attained automated action. It is thought that by understanding that expert golfers reduce the chance of missing putts in a high-pressure environment by consistently over-shooting the target in a low-pressure environment.

    Introduction: It is well known that the size and strength of skeletal muscle decreases with increasing age (sarcopenia), notably in the knee extensor muscles. Recent studies have indicated that university students in Japan have low levels of physical activity, and that muscle strength of the lower extremities decreases every year. Therefore, physical fitness for university students should be focused on the size/strength of the knee extensor muscles. However, an appropriate physical fitness test to evaluate knee extensor muscle strength and size in university students has not been designed. Purpose: The purpose of this study was to examine the relationship between knee extensor muscle strength and size and physical fitness results in university freshmen male students. Methods: University students from the faculty of science and engineering in Toyo University participated in the study (N=116). The muscle thickness (MTH) of 104 healthy men (aged 18-20 years) was measured at the anterior half of thigh length; they performed maximal voluntary isometric strength (MVC) of knee extensors. Physical fitness [30-second chair stand (CS-30) test, standing broad jump (SBJ), handgrip and thigh girth at 50% of thigh length (mid-thigh girth)] were also measured. Results: The following were similar to the standard values of the overall Japanese population for the same age group: age (18.2 ± 0.5 years), standing height (1.71 ± 0.48 m), body mass (62.9 ± 7.9 kg), body mass index (BMI, 21.6 ± 2.6), MVC (41.4 ± 12.2 kg), MTH (52.3 ± 6.6 mm), CS-30 (33.1 ± 4.3 reps), SBJ (2.13 ± 0.20 m), handgrip (41.2 ± 6.4 kg) and mid-thigh girth (50.8 ± 4.3 cm). Knee extensor MVC was correlated with SBJ (r=0.361, p<0.001) , hand grip (r=0.523, p<0.001) and mid-thigh girth (r=0.401, p<0.001), but not with CS-30 test (r=0.126, p>0.05). Knee extensor MTH was correlated with handgrip (r=0.317, p<0.001) and mid-thigh girth (r=0.632, p<0.001), but not with SBJ (r=0.038, p>0.05) and CS-30 test (r=0.145, p>0.05). Conclusions: Our results indicated that the measurements of handgrip and mid-thigh girth are useful methods for evaluating knee extensor muscle strength and size, and thus they could play an important role in the physical fitness of university freshmen male students for the prevention of sarcopenia and to maintain an active life in the future.

    One of the popular training methods to improve sport performance is medicine ball (MB) training. MB training can increase the speed of trunk rotation or the stability of the trunk. Theoretically, both of those changes in a kinetic chain of the body can cause a positive effect on golf swing mechanics; however the effect of the training on golf performance is still unclear. Thus, the purpose of this study was to clarify the effects of 8 weeks of MB training on golf performance for skilled golfers. Methods: Fourteen competitive university golfers undertook 1 hour of MB training session 3 times a week for 8 weeks. The average golf best score of the participants was 72.4 ± 4.0 with a handicap of 6.4 ± 4.7 (Table 1). Five MB throwing techniques were selected for the training 1) Front throw, 2) Back throw 3) Side throw-right, 4) Side throw-left, and 5) Over head throw. Additional stationary trunk exercises were also executed within the training time period. Kinematic and kinetic variables were obtained while the golfers hit the ball with their 1 Wood club before (Pre) and after (Post) the training program. A three dimensional motion analysis system (Qualisys, Sweden) consisting of eight high speed cameras synchronized with two force plates (Bertec, USA) were used for data collection. Kinematic variables include 1) Club head linear speed, 2) Maximum shoulder angular velocity, 3) Maximum pelvic angular velocity, and 4) Maximum left wrist linear velocity. Vertical component of maximum ground reaction force was also obtained from the participants’ left foot. Distance of the five MB throwing techniques was also measured at Pre, after 4 weeks (Mid), and Post. A one-way repeated measures ANOVA was used to test the difference of the MB throwing distance among Pre, Mid and Post measurements. A student t-test was used to test the difference of the kinematic and kinetic data between Pre and Post measurements. Results: The major findings of the study were as follows. The distance of MB throwing techniques significantly increased over Pre to Mid in all of the five throwing techniques and further significantly increased over Mid to Post in Back throw, Side throw-right and Side throw-left (Table 2). No significant increase was found in club head speed (CHS) during the swing (Table 3); however there was a trend of increase in CHS (1.4 ± 3.0 % change, P = 0.114). Angular velocity of the shoulder as well as hip velocity did not significantly change in golf swing or MB throwing technique. A significant increase was found in the maximum left wrist linear velocity and the left foot maximum ground reaction force during the MB throwing technique (P < 0.05, Table 3). Discussion: A significant increase was found for the maximum left wrist velocity and left foot maximum ground reaction force in the MB throwing measurement; however these changes did not cause any positive effect on the kinematical variables during the golf swing. We believe that time period was not long enough for the golfers to incorporate these changes into their golf swing mechanics. A significant increase in the distance of MB throwing indicated that there was a change in the way of generating power in the golfers’ body. Further investigation is recommended to examine the long-term effects of MB training on golf performance. Practical Application/ Clinical Relevance: Eight weeks of MB training can change the way of generating power in the golfers’ body. Major benefit of the training could be an improvement of trunk stabilization and an increase in arm swing speed. Longer post training period may be necessary to transfer these changes into the golfer’s swing mechanics in skilled golfers.

    Functional training has become very popular in golf training. There is variety of training equipment in the market, and previous studies reported the effect of functional training on golf using various equipment. One of the newest equipment for functional training is ViPR (Vitality Performance Reconditioning). The ViPR consists of a cylinder-like rubber tube (4 to 20 kg) with two handles mounted on it. The shape of the ViPR allows the trainee to move it in various ways with a tight grip. Because it is relatively new to the market, there is no previous scientific study on the effect of the ViPR. Thus, the purpose of this study is to scientifically investigate whether ViPR training is an effective method of training for competitive golfers. Methods: In this study, under the guidance of 2 specialist instructors for ViPR, 5 competitive university golfers undertook 40 minutes of ViPR functional training 3 times a week for 5 weeks. Main exercises of the training were 1) walking lunge press, 2) standing twist, 3) front skaters, 4) lunge and press and 5) medicine ball rebounder (Figure 1). Each of these exercises was executed 35 to 45 seconds in a circuit training format with 40 to 30 second resting intervals between each exercise. In the each training period, the participants completed 4 to 5 sets of the training. Before and after the entire training period, we obtained ball trajectory data using TrackMan system (TrackMan A/S, Denmark) while the golfers hit the ball with their 5 Iron and 1 Wood club. In all shots, the 3 highest scoring shots on an introspective scale of 1 to 5 were used for the data analysis. Post training TrackMan data was obtained after a one week de-training period after the conclusion of the training program. Physiological data were also obtained at each training period. Results: The average golf score of the participants was 71.6 ± 2.7 with a handicap of 5.6 ± 2.1 (Table 1). No significant difference was found between body weight, body mass index, percentage of skeletal muscle for the whole body and basal metabolism during the 5-week training period (Table 2). Average heart rate (after training) was significantly decreased between week 2 and week 4, as well as between week 2 and week 5 (P < 0.05, respectively; Table 3 and Figure 2). A significant difference was found in the spin rate for 5 Iron between pre and post measurements. (Pre：5176 ± 776 rpm, Post：4561 ± 554 rpm, P < 0.05, Table 4). Discussion: Firstly, we found there was an effect of ViPR functional training on golf performance only on the spin rate of the 5 Iron golf shot. Reduction in back spin rate causes less lift of the golf ball which theoretically leads to a more predictable shot distance for each club. The effect of the training on golf performance was found in only this variable. However, the changes in body motion in all exercises in ViPR were obvious from the trainers’ point of view. We believe that there was a change in the movement pattern in the golfers, but this change was not transferred to their golf swing. We concluded that 5 weeks of the ViPR training was not long enough to alter the golf performance in competitive golfers. Secondly, the training improved cardiopulmonary adaptation in the golfers despite the outside temperature progressively becoming lower over the 5-week training program. It is recommended that ViPR training is effective for improving golfer’s fitness level during pre-season or off-season training programs. Practical Application/ Clinical Relevance: We used the ViPR as a form of circuit training. Exercise and rest times were displayed using a basketball game timer so the participants were able to know how long the exercise lasted. This could lead the participants concentrate on the training. Each of the fives exercises lasted 30 seconds and the resting intervals 40 seconds at the week 1 of the training period. The exercise time get longer (as long as 45 seconds) and the resting intervals get shorter (as short as 30 seconds) toward the end of the training period. The training sets started from 3 and ended 5 through the 5 weeks. It is recommended to begin ViPR training with a light weight and short period of exercise time.
