Braking hazards of golf cars and low speed vehicles.

Research and analysis of braking issues for golf cars and other low speed vehicles (LSVs) are reported in this study. It is shown that many such vehicles only provide braking for their rear wheels, which can lead to a driver losing control during travel on typical steep downgrades. The braking performance of a golf car equipped with brakes on two or four wheels was analyzed to determine the effects of two and four wheel brake designs on braking efficiency and vehicle yaw stability. Besides reducing braking efficiency, it is demonstrated that installing brakes on only the rear wheels can lead to directional instability (fishtailing) and rollover when the rear wheels are braked until skidding occurs. The nonexistence of golf course standards and the inadequacy of golf car and LSV standards are noted and a connection between this and the comparatively high level of accidents with such vehicles is inferred. Based on these results, it is advisable to install brakes on all four wheels of golf cars and LSVs. In addition, new safety standards should be considered to reduce the occurrence of golf car accidents on steep downhill slopes.

Golf: an olfactory neuron specific-G protein involved in odorant signal transduction.

Biochemical and electrophysiological studies suggest that odorants induce responses in olfactory sensory neurons via an adenylate cyclase cascade mediated by a G protein. An olfactory-specific guanosine triphosphate (GTP)-binding protein alpha subunit has now been characterized and evidence is presented suggesting that this G protein, termed Golf, mediates olfaction. Messenger RNA that encodes Golf alpha is expressed in olfactory neuroephithelium but not in six other tissues tested. Moreover, within the olfactory epithelium, Golf alpha appears to be expressed only by the sensory neurons. Specific antisera were used to localize Golf alpha protein to the sensory apparatus of the receptor neurons. Golf alpha shares extensive amino acid identity (88 percent) with the stimulatory G protein, Gs alpha. The expression of Golf alpha in S49 cyc- kin- cells, a line deficient in endogenous stimulatory G proteins, demonstrates its capacity to stimulate adenylate cyclase in a heterologous system.

The role of the shaft in the golf swing.

Current marketing of golf clubs places great emphasis on the importance of the correct choice of shaft in relation to the golfer. The design of shafts is based on a body of received wisdom for which there appears to be little in the way of hard evidence, either of a theoretical or experimental nature. In this paper the behaviour of the shaft in the golf swing is investigated using a suitable dynamic computer simulation and by making direct strain gauge measurements on the shaft during actual golf swings. The conclusion is, contrary to popular belief, that shaft bending flexibility plays a minor dynamic role in the golf swing and that the conventional tests associated with shaft specification are peculiarly inappropriate to the swing dynamics; other tests are proposed. A concomitant conclusion is that it should be difficult for the golfer to actually identify shaft flexibility. It is found that if golfers are asked to hit golf balls with sets of clubs having different shafts but identical swingweights the success rate in identifying the shaft is surprisingly low.

Effects of golf course construction and operation on water chemistry of headwater streams on the Precambrian Shield.

To investigate the effects of golf course construction and operation on the water chemistry of Shield streams, we compared the water chemistry in streams draining golf courses under construction (2) and in operation (5) to streams in forested reference locations and to upstream sites where available. Streams were more alkaline and higher in base cation and nitrate concentrations downstream of operational golf courses. Levels of these parameters and total phosphorus increased over time in several streams during golf course construction through to operation. There was evidence of inputs of mercury to streams on two of the operational courses. Nutrient (phosphorus and nitrogen) concentrations were significantly related to the area of unmanaged vegetation in a 30 x 30 m area on either side of the sampling sites, and to River Bank Quality Index scores, suggesting that maintaining vegetated buffers along the stream on golf courses will reduce in-stream nutrient concentrations.

Is there an association between self-reported warm-up behaviour and golf related injury in female golfers?

Golfing injuries have been shown to occur frequently, and injury countermeasures have been suggested to help reduce injury risk. Performing an appropriate warm-up is thought to reduce injury risk, however there is a lack of evidence to support this notion. Therefore this study aimed to investigate the relationships between warm-up participation and injury in a cohort of female golfers. A total of 522 golfers participating in the Victorian Women's Pennant Competition completed the study. Over one-third (35.2%) of the golfers reported having sustained a golfing injury within the previous 12 months, with the lower back the most commonly injured region. Most golfers reported not warming-up prior to play or practice. Golfers who reported not warming-up on a regular basis were more likely to have reported a golfing injury in the previous 12 months than those reporting frequent warm-up participation (OR=45.2; 95% CI: 13.5, 151.7). Less skilled golfers were also less likely to report sustaining a golfing injury than more skilled golfers (OR=0.2; 95% CI: 0.1, 0.5). This study is one of the few to establish an association between warm-up participation and injury. Further prospective studies are warranted to determine whether warm-up reduces injury risk for golf participation.

Golf injuries and rehabilitation.

There are more than 25 million golfers in the united States, and many have an injury related to golf. Low back injuries are the most common golf injuries, followed by elbow injuries. Successful treatment of golf injuries often includes modification of the golf swing. Adaptations allow many individuals, including those who are physically challenged, to enjoy playing golf.

Vertebral compression fractures sustained during golfing: report of three cases.

Considerable concern has been expressed about the type and level of exercise that are safe for women with osteopenia and osteoporosis; however, published information on the effect of golfing on the osteoporotic spine is meager. We describe three postmenopausal patients with acute compression fractures of the vertebrae that occurred during midswing while golfing. These healthy, active women were long-term golfers; their ages at the time of the trauma were 63, 58, and 66 years. In one patient (case 1), osteoporosis was diagnosed before the golf-related injury. The two other patients (cases 2 and 3) sought medical attention after the trauma and were found to have osteoporosis. The bone mineral density of the lumbar vertebrae (L2-4) in the three patients at the time of or shortly after the trauma was as follows: case 1, 0.77 g/cm2 (3rd percentile of normal, corrected for age); case 2, 0.63 g/cm2 (less than 1st percentile of normal, corrected for age); and case 3, 0.69 g/cm2 (2nd percentile of normal, corrected for age). These findings raise the issue of the safety of golfing for women with previously diagnosed osteoporosis and for those with predisposing risk factors for the disease. Research studies of the kinematics and kinetics of the spine during the golf swing should be conducted. In the interim, a rigid back support for golfers with osteoporosis may be helpful until more conclusive evidence is available from controlled trials.

Golf injuries--common and potentially avoidable.

Injuries sustained during golf rarely receive the recognition given to injuries from sports perceived as more violent or strenuous. However, golfing injuries are believed to occur frequently. The aim of this study was to explore the injury profile of female golfers, including treatment sought and the impact of the injury on performance and participation. Forty-one team captains were given questionnaires to distribute to their players. A total of 522 golfers participating in the Victorian Women's Pennant Competition in Victoria, Australia, from both the Metropolitan and Country competitions, completed the study. Over one-third (35.2%) of the golfers reported having sustained a golfing injury within the previous 12 months, with the lower back being the most commonly injured body region. Strains were the most frequent type of injury (67.9%). Of the 184 injuries reported, 154 sought treatment from a health professional. Physiotherapists were the most common health professional consulted. Performance was affected in 78.9% of cases, with 69.7% of the injured golfers missing games or practice sessions due to injury. Golfing injuries appear common and have a substantial impact upon the injured golfer. As lower back strains are the most common injury, strategies such as performing an appropriate warm-up could be investigated to determine the possible injury prevention benefits for golfers. This study has also highlighted that the majority of treatments are from allied health professionals, suggesting that a complete epidemiological description of golf injuries requires information from broader settings than general practice clinics and hospitals.

Cardiac arrest on the links: are we up to par? Availability of automated external defibrillators on golf courses in southeastern Pennsylvania.

OBJECTIVES: A growing number of golfers are senior citizens, and it may be predicted that the number of golf-related medical emergencies, including the incidence of cardiac arrest, will increase. This study was designed to survey the level of preparedness of golf courses in southeastern Pennsylvania to respond to cardiac arrest among their members. METHODS: A telephone survey of all of the 180 golf courses in the area was conducted to determine their type (public/private), volume in rounds per year, presence of automated external defibrillator (AED) devices, number of employees, and percentage of employees with cardiopulmonary resuscitation (CPR) training. Participants also were asked to estimate the time needed to reach the farthest point on their course in order to estimate a maximum time to the application of an AED device. RESULTS: A total of 131 of 180 golf courses completed the survey (53 private, 78 public) for an overall response rate of 73%. Private courses reported a greater average number of employees with CPR training [private = 9.1, public = 3.6; p = 0.001] and in AED presence [public = 9%, private = 58.5%; p = 0.0001]. Public courses support a higher volume of play than do private courses [public = 32,000, private = 24,000; p = 0.001], yet have far fewer employees [public=25, private=44; p = 0.004]. The longest time necessary to reach the most remote point on the course was between four and five minutes in all courses. Analysis was performed using the Student's t-test and Pearson's Chi-square as appropriate. CONCLUSION: Neither public nor private golf courses are well equipped to respond to cardiac arrest, but outcomes on public courses likely are to be far worse.

Salivary cortisol, testosterone, and T/C ratio responses during a 36-hole golf competition.

The purpose of this investigation was to study the effects of 36 continuous holes of competitive golf on salivary testosterone, cortisol, and testosterone-to-cortisol ratio and their relation to performance in eight elite male collegiate golfers (age 20.3 [+/- 1.5] years). Thirty-six holes of a 54-hole NCAA golf tournament were played on the first day of the competition. A saliva sample was taken 45 minutes prior to the round and immediately following each hole for a total of 37 samples per subject. Time matched baseline samples were collected on a different day to account for circadian variation. Six-hole areas under the curve (AUC) values were calculated for endocrine measures. Significant (p < 0.05) increases were noted for cortisol during competition, however, testosterone did not change during competition compared to baseline. Testosterone-to-cortisol (T/C) ratio was significantly lower throughout the competition compared to baseline measures. Thirty-six-hole AUC testosterone-to-cortisol ratio response was correlated (r = 0.82) to 36-hole score. There was a high correlation between pre-round testosterone (r = 0.71), T/C ratio response (r = 0.82), and 36-hole score. CSAI-2 somatic anxiety was correlated to pre-round cortisol (r = 0.81) and testosterone (r = - 0.80) response. These results indicate a significant hormonal response during 10 hours of competitive golf. Good golf performance (low golf scores) in this competition was related to low T/C ratio (r = .82). Additionally, results from this investigation validated CSAI-2 somatic anxiety with physiological measures of anxiety.

[Golf with total joint replacement of the hip and knee].

Playing golf after THR and TKR is discussed controversially by orthopedic surgeons and Data of 16 patients receiving 22 THR (18 m/4f, 12 r/10 l) and of 11 patients receiving 12 TKR (9 m/3f, 6 r/6 l) were analysed using a questionnaire. The mean age of THR-/TKR-sportsmen was 65,7 (58 - 78)/67,8 (61-76) years. In THR-/TKR-patients surgery was done 59 (12-226)/39 (12-105) month ago. The best handicap (hcp) in their carrier/one year before/one year after surgery was in THR 15,7 (2-36)/18,5 (6-36)/17,7 (4-36), in TKR 18,4 (6-24)/22,1 (8-34)/20,3 (8-28). 11/7 sportsmen with THR/TKR could preserve the level of hcp following surgery, in 7/0 hcp became worse and in 4/5 hcp was even better. Patients with 21 THR and 12 TKR had less pain while playing golf in the operated joint one year after compared to one year before surgery, 1 patient with THR suffered more pain. During follow-up 13 THR/10 TKR reported of no problems playing golf, 7 THR/2 TKR had moderate pain, 2 THR/0 TKR had severe pain, no patients was unable playing golf following the joint replacement. Golf can be recommended as sporting activity after successful THR and TKR.

Training in timing improves accuracy in golf.

In this experiment, the authors investigated the influence of training in timing on performance accuracy in golf. During pre- and posttesting, 40 participants hit golf balls with 4 different clubs in a golf course simulator. The dependent measure was the distance in feet that the ball ended from the target. Between the pre- and posttest, participants in the experimental condition received 10 hr of timing training with an instrument that was designed to train participants to tap their hands and feet in synchrony with target sounds. The participants in the control condition read literature about how to improve their golf swing. The results indicated that the participants in the experimental condition significantly improved their accuracy relative to the participants in the control condition, who did not show any improvement. We concluded that training in timing leads to improvement in accuracy, and that our results have implications for training in golf as well as other complex motor activities.

Carcinogenic and genotoxic potential of turf pesticides commonly used on golf courses.

As a result of the controversy surrounding pesticide use and animal and human health concerns, many municipalities in Canada have restricted, or are in the midst of restricting, the use of pesticides for cosmetic purposes. In some cases, pesticide use on golf courses is also being phased out at the municipal level. One of the dominant health effects of concern in relation to pesticide exposure is the occurrence of cancer. With over 1600 golf courses in Canada and between 400 and 600 new courses created each year in Canada and the United States, there appears to be increasing potential for unintentional human and animal exposure to turf pesticides. In light of the debate around pesticide exposure and the onset of cancer that has lead to controversial Canadian municipal bylaws regulating pesticide use, and due to recent results of a biomonitoring study that has shown genotoxicity in a rodent species living in golf-courses, it seems timely to review the carcinogenic and genotoxic potential of commonly used golf-course pesticides. The purpose of this review is to present some debated epidemiological research that deals with the relationship between pesticide exposure and cancer, and to review and update the literature on the in vivo and in vitro mammalian carcinogenic and genotoxic potential of these pesticides. It is our intention to unite information from various sources so those interested specifically in the carcinogenicity and genotoxicity of pesticides commonly used on golf courses can refer to one comprehensive and updated resource.

Golf cart related injuries in a North Carolina island community, 1992-4.

OBJECTIVES AND METHODS: The use of electric golf carts for roadway transportation is increasing in many regions of the United States, but injuries associated with the operation of these vehicles have not been previously described. In response to reports of golf cart related injuries in a North Carolina island community, we reviewed ambulance call report (ACR) information to identify and describe all injuries related to golf cart operation in this community in 1992-4. We also conducted telephone interviews with the subset of injured people who consented to be contacted. SETTING: Bald Head Island, North Carolina. RESULTS: Twenty two people were included in the case series, and 55% of these provided interview information to supplement ACR data. Fifty nine per cent of the 22 injured people were injured when they fell from a moving golf cart; of those injured in this manner, all with available information on seating position were passengers (rather than drivers). Eighty six per cent received immediate medical treatment at a mainland hospital. Thirty two per cent of injury incidents occurred among children aged 10 or younger. Forty per cent of injured adults were known to have been drinking alcohol before their injuries occurred, while alcohol was not known to have been involved in any of the children's injuries (in terms of drinking either by children or by accompanying adults). CONCLUSIONS: In settings where golf carts are used for road transportation, their users and traffic safety officials should be aware of potential safety hazards associated with the use of these vehicles, and installation of appropriate occupant restraints should be considered seriously.

Injuries and overuse syndromes in golf.

BACKGROUND: Although golf is becoming more popular, there is a lack of reliable epidemiologic data on golf injuries and overuse syndromes, especially regarding their severity. OBJECTIVE: To perform an epidemiologic study of the variety of different musculoskeletal problems in professional and amateur golfers and to find associations of age, sex, physical stature (body mass index), warm-up routine, and playing level with the occurrence of reported injuries. STUDY DESIGN: Retrospective cohort study. METHODS: We analyzed the injury data from a total of 703 golfers who were randomly selected over two golfing seasons and interviewed with the use of a six-page questionnaire. RESULTS: Overall, 82.6% (N = 526) of reported injuries involved overuse and 17.4% (N = 111) were single trauma events. Professional golfers were injured more often, typically in the back, wrist, and shoulder. Amateurs reported many elbow, back, and shoulder injuries. Severity of reported injuries was minor in 51.5%, moderate in 26.8%, and major in 21.7% of cases. Carrying one's bag proved to be hazardous to the lower back, shoulder, and ankle. Warm-up routines were found to have a positive effect if they were at least 10 minutes long. CONCLUSIONS: Overall, golf may be considered a rather benign activity, if overuse can be avoided. If not, golf can result in serious, chronic musculoskeletal problems.

Sediment chemical contamination and toxicity associated with a coastal golf course complex.

The increasing density of golf courses represents a potential source of sediment contamination to nearby coastal areas, the chemical and biological magnitude of which is almost unknown. The objective of this study was to determine the concentrations of contaminants and toxicities of sediments impacted by a coastal golf course complex. Sediment contaminant concentrations were determined at least twice during the two-year study period at 14 sampling stations. In addition, a combination of acute and chronic bioassays were conducted exposing four invertebrate test species to whole sediments and associated pore waters. Overall, the Florida, USA, golf course complex had a measurable impact on sediment chemical quality, particularly in near-field areas. Higher concentrations of several trace metals and organochlorine pesticides were detected in many golf course-associated sediments compared with reference areas; however, concentrations decreased seaward and only a few, primarily chlorinated pesticides, exceeded proposed sediment quality guidelines. Chromium, zinc, and mercury were detected more frequently than other trace metals. The DDT and associated metabolites, dieldrin and chlordane, were the more commonly detected organic contaminants. Acute toxicity was uncommon and occurred consistently for sediment collected from one coastal location. In contrast, chronic toxicity occurred at several study sites based on the response of Mysidopsis bahia. It was concluded that the impact of golf course runoff on sediment quality may be subtle and sensitive biological assessment methods, such as chronic toxicity tests, will be needed to detect adverse effects.

Golfing injuries. An overview.

Golf is becoming an increasingly available and popular sport. It is played by people of all ages and abilities, which accounts for a wide spectrum of injury. Few reports of injuries exist, but increasing media attention of the golfing injuries of professional players has raised the profile of these medical conditions. Numerically, the vast majority of problems occur from soft tissue musculoskeletal injuries rising principally from overuse. The injury pattern seen is influenced by the age, ability and amount of play. Anatomically, most injuries are localised to the back, wrist, elbow and shoulder. In addition to causing new injuries the game may cause recrudescence of old injuries and exacerbate pre-existing degenerative disease. A different injury pattern is seen among elite players compared with recreational players, and this relates to skill and amount of practice. Appropriate conditioning and attention to technique may help to reduce the incidence of injury. There are no injuries exclusive to golf, however fracture of the hamate bone is an uncommon injury seen in sports involving the use of a club or bat. The high number of childhood golf-related head injuries is disturbing. Most of these arise from blows to the head from a golf club and highlight the need for early tuition in the safety aspects of the game.

Reuse of reclaimed wastewater for golf course irrigation in Tunisia.

In Tunisia, golf courses are irrigated with secondary treated effluent stored in landscape impoundments. The impact of the conveyance and storage steps on the physical-chemical and biological quality of irrigation water was evaluated on three golf courses over two years. It was found that the water quality varies all along the water route, from the wastewater treatment plant up to the irrigation site: nutrient and bacteria contents decreased along the route in the three cases. This variation depends on the wastewater quality, the length of the pipes conveying water, the number of regulation reservoirs and ponds, the water residence time in pipes, reservoirs and ponds, and the operation of the ponds. The bacteriological quality of irrigation water deteriorates during the irrigation period in the three golf courses as the ponds are operated as continuous flow reactors. The results obtained in this study indicate the inability of golf water supplies, as currently managed, to properly sanitize reclaimed wastewater and meet target quality criteria recommended by WHO (1989) for water intended for recreational use. For a safe reuse of reclaimed wastewater for golf course irrigation, changes in the design and operation of the ponds should be planned or additional treatment steps provided.
