PURPOSE: Our previous studies showed that experienced Tai Chi practitioners had better joint proprioception and balance control during weight shifting. The objective of the present study was to examine whether experienced golfers had attained similar improvement when compared with the Tai Chi practitioners, as well as healthy elderly subjects and young university students. METHODS: We compared 12 experienced elderly Tai Chi practitioners, with 11 experienced elderly golfers, 12 healthy elderly subjects, and 12 young university students, who were all males, using: 1) passive knee joint repositioning test to assess their joint proprioceptive acuity and 2) limits of stability test to assess their ability to voluntarily weight shift within their base of support. RESULTS: Both Tai Chi practitioners and golfers had better knee joint proprioceptive acuity than did the elderly control subjects (P < 0.05). Of special interest is that their performance was similar to that of the young subjects. In the limits of stability test, Tai Chi practitioners and golfers had faster reaction time, leaned further without losing stability, and showed better control of leaning trajectory than did elderly control subjects (all P < 0.05). The latter two outcome measures were also comparable to those of the young subjects. CONCLUSION: These results demonstrate that both experienced Tai Chi practitioners and golfers had improved knee joint proprioception and limits of stability, when compared with those of elderly control subjects similar in age, gender (male), and physical activity level. Such improved outcome measures were comparable to those of young male subjects. These findings suggest that experienced Tai Chi practitioners and golfers had improved joint proprioceptive acuity and dynamic standing balance control, despite the known aging effects in these specific sensorimotor functions.
Researchers have investigated the relationship between different shot-making measures and performance on the PGA Tour. Prior studies have typically focused on a short period of time or used a restricted sample so long-term trends were not discernible. To remedy this situation, the present study looked at the longitudinal performance of professional golfers from 1990-2004. The findings indicated a remarkable stability in terms of the relative importance of Greens In Regulation and Putting Average in explaining the variability in Scoring Average. The findings also indicated a declining importance of driving in recent years due, in part, to a strengthening of the negative relationship between Driving Distance and Driving Accuracy.
This study investigated whether the lack of day-to-day consistency in performance for professional golfers would occur if round ranks were employed instead of round scores. When players' round scores from the 2004 Clark study were converted to round ranks, the results were very similar to those found in that study. It was concluded that the range of abilities for professional golfers is so restricted that the fluctuation in players' scores or rankings will show little consistency from day to day.
The purpose of this research was to investigate if aikido training for 10 weeks for 69 beginning students is effective in improving selected aspects of personality. The hypothesis was that subjects' scores would significantly increase on self-esteem but decrease on anxiety and anger expression. Change in means from pre- to posttest did not support the hypothesis.
Analysis of 1998 statistics for individual performance in the PGA European Tour yielded significant differences between some shot-making skills (drive distance, total driving, greens in regulation, and sand saves) between the top 10 and bottom 10 money winners, replicating (with partially different results) a result found for the 1995 American PGA Tour by Engelhardt.
The purpose of this study was to clarify golfers' scanning patterns while putting through direct measurement of their eye movements. Each of the 17 subjects (3 experts, 3 intermediates, 11 beginners) performed 10 consecutive putts on a practice mat, from a position 2 m from the hole. The analysis of their eye-movements indicated differences among these groups. The intermediates and beginners had longer fixation durations on the ball than the experts. The beginners exhibited a range of behaviors among the trials, some of which did not include any fixations on the ball. Experts held their eyes steady but did not fixate on the ball. These results suggested that experts may have relied on a mental image of the ball; in contrast, the intermediates and some of the beginners relied on visual data.
In using an ISP in conjunction with a structured rehabilitation program, the athlete should be able to return to full competition status. The general guidelines and specific programs outlined are used to minimize the chance of reinjury and to facilitate the return of function and confidence in the athlete. The program and its progression should be modified to meet the specific needs of each individual athlete. A comprehensive program consisting of a propter maintenance rehabilitation program incorporating strengthening, flexibility, plyometric, dynamic stabilization, and neuromuscular controls drills, as well as appropriate warm-up procedures and biomechanics, is essential in returning athletes to competition as quickly and safely as possible.
