<p>Football is the most popular sport in the world, and it continues to have a progressive annual increase in the number of active players and the number of games played per season, which in turn, leads to an increase in the frequency of injuries. Football is extensively researched worldwide, however, some current studies confirm that the results on football injury factors are limited, as well as inconsistent and incomplete. The main aim of this study was to examine interrelating factors of football injuries through the various age groups at a designated football club. The study aimed to expose the injury risk factors and patterns present in the various age groups.</p>

Background: The International Football Federation (FIFA), through their Goal project, renovated Rufaro stadium from natural turf (NT) to artificial turf (AT). This was met with mixed feelings especially with regard to injuries sustained by football players. There is no published scientific data on football injuries in Zimbabwe. Aim: To determine the frequency of injuries on AT and NT among Premier Soccer League (PSL) players in Zimbabwe. Objectives: To determine the attitudes of players regarding the different football playing surfaces, and the incidence, severity and injury types on AT and NT. Methods: The 2013 season's16 PSL teams were selected to complete questionnaires and injury report forms. Injuries recorded during matches on AT and NT were analyzed. Outcome measures were injury incidence (injuries/1000 player hours (Phrs) of exposure)compared for AT and NT using rate ratios (95% confidence intervals). All statistical significance were set at p<0.05. Results: A total of 325 players responded and 295(90.8%) preferred playing on NT. Of these, 250(76.9%) believed that AT was associated with more injuries. A total of 364 injuries occurred during 4455phrs of exposure giving an injury incidence of 81.7 injuries/1000phrs.A total of 69 games (1138.5phrs) on AT revealed an injury incidence of 85.2 injuries/1000phrs while 201 games (3316.5 phrs) on NT revealed an overall incidence of 80.51 injuries/1000-hrs.This analysis showed no statistically significant difference in the incidence of injury between AT and NT surfaces during matches played, [RR= 1.06; 95% CI: 0.84 – 1.34]. With regard to injury severity, the highest incidence occurred on the AT (31.62/1000phrs in the mild category) and the lowest incidence was on the NT (1.81/1000 phrs in the severe category) .The rate ratios for the severity were however not statistically significant. Comparison of the injuries according to body part injured largely revealed insignificant rate ratios. Conclusion: Football players believe that the AT is associated with increased risk of injury. There was no significant difference in injury incidence rates and severity between the AT and NT during the 2013 PSL season in Zimbabwe. The incidence of injury in this study was much higher than comparable European studies and is a need for further studies to explore the underlying reasons for this.

Very little information exists about the acute presentation of overuse injuries specific to cycling. Although there are studies, mainly in the form of surveys, that do detail the incidence and prevalence of overuse injuries in cyclists or triathletes, they all take place weeks or even months after events or focus on a 1 year injury history. (Weiss 1985, Korkia et al. 1994, Wilber 1995, Manninen and Kallinen 1996 and Salai et al. 1999) The aim of this study was to describe the historical data obtained when patients presented to the Student Chiropractic Sports Council at the Pick ‘n Pay 94.7 Cycle Challenge from the years 2002 to 2004. The focus of the study was on the profile of injuries with which patients presented. This was a descriptive study of historical data obtained by students treating at the Pick ‘n Pay 94.7 Cycle Challenge from the year 2002 to 2004. The data was acquired in the form of SOAP (Subjective, Objective, Assessment, Plan) notes held by the Student Chiropractic Sports Council. The results of this study showed that the most common location of complaints were the anterior and posterior thigh. Musculotendinous strains were by far the most predominant injury with the hamstring being involved more commonly (33.8%) than any other muscle. Overall 72.8% of patients were diagnosed with musculotendinous strains. Further, the results also showed that 55.8% of patients complained of eck or back pain and 59.7% were diagnosed with cervical facet joint, thoracic facet joint, lumbar facet joint or sacroiliac joint dysfunction. / Dr. S.

Fast bowlers are especially prone to injury as they perform their bowling techniques repetitively at very high intensities. The fast bowling action in the past has been described as a highly explosive activity that produces high levels of stress and strain on the body. The aim of this study was to compile an injury profile of 46 fast bowlers aged 11 to 18, and to identify the associated risk factors for injury during an academy cricket season. A descriptive correlational research design was utilised. Subjects were selected according to age and fast bowling ability. These subjects were observed for one academy cricket season (March to November). Three testing sessions occurred during this time (T1, T2 and T3). Each subject completed two questionnaires: i) bowler history (at T1) and ii) injury history (at T1, T2, and T3). These assisted in grouping the subjects according to their responses into one of three injury classifications (uninjured = S1; injured but able to play = S2; injured and unable to play = S3). Anthropometric and postural data for the entire group of fast bowlers were also collected pre-season (T1). Physical fitness screenings were also conducted during each of the three testing sessions to establish any relationship between the fitness of each fast bowler and the occurrence of injuries. Additional factors assessed during the season were bowling techniques and bowling workload. Statistical significance was indicated by p-values less than .05 (p< .05), while practical significance was indicated by either Cohen’s d-values of 0.2 or better (d>0.2) for tests based on sample means or Cramer’s V for tests based on sample frequencies, the values of which depend on the applicable degrees of freedom. All fitness scores as well as bowling workload figures for each testing session were converted to standard T-scores and these in turn were summated to derive overall fitness and workload T-scores. ‘TT’ indicated the overall average score for the entire season. Changes in performances, bowling workload and injury status were analysed using ANOVA and ANCOVA. A regression analysis was also conducted to analyse the relationship between bowling workload and weeks incapacitated. This study found that hyperextension in the knees had the highest incidence of postural deviation injury (43 percent) followed by winged scapula (39 percent). Only 15 percent of the fast bowlers remained injury-free for the duration of the season, while 35 percent of the subjects were at some stage injured to such an extent that they were unable to play. The incidence of serious injury (S3) showed a statistical and moderate practical (V=0.23, d.f. ≥2) significant increase throughout the data collection period (4 percent at T1 to 30 percent at T3). The most common injury was to the knee (41 percent) followed by those to the lower back (37 percent). These injuries occurred mostly during test periods T2 and T3. The nature of injuries were predominantly strains and "other" which accounted for 39 percent of the injuries overall (TT) and had the highest reported incidence during the period T1 to T3. Sprains followed with an overall incidence of 14 percent. Less frequently reported injuries were tears, fractures, bruises and dislocations. The degree of severity of injuries was defined in terms of the number of weeks a player reported being incapacitated as a result of injury during the academy session. During midand end-season bowlers were on average incapacitated approximately one week out of every five due to injury. The statistics for the duration of the study translate to approximately one week incapacitated out of every seven weeks of play. When comparing the S1/S2 bowlers with the S3 group, the S1/S2 bowlers performed consistently better than the S3 bowlers in all the fitness variables tested. However no significant differences (p>.05) in either flexibility or muscle strength were observed. Of the risk factors analysed, bowling workload presented a statistically significant (p<.0005) increased risk for injury. A strong significant positive relationship (p<.0005, R²=.619) was found between weeks incapacitated and bowling workload, supporting the finding that increased bowling workloads show a linear relationship with the increase in the number of weeks incapacitated from normal play. This study concluded that inadequate fitness, high bowling workload and bowling technique all have a multi-factorial role in predisposing a bowler to increased risk for injury. These variables did not act alone, but have all contributed to recurring injuries. The bowling action alone would not have been detrimental if the workloads were not in excess of the recommended guidelines. Furthermore the workload would not have been as detrimental if the bowlers were well conditioned and uninjured. Management of minor injuries and adequate recovery time, coupled with adequate and relevant fitness preparation would better prepare fast bowlers for the demands of the game.
