Book excerpt: Objective: The objective of this study was to determine the ability of the Star Excursion Balance Test (SEBT) to reliably and accurately predict lower extremity injuries in high school football players. Design: This study used a prospective cohort design. Subjects: Two hundred and thirty nine male junior varsity and varsity football players from five different high schools around the greater Toledo, Ohio area were recruited for this study. Measurements: Each subject was tested by a group of certified athletic trainers on three reach distances of the SEBT: anterior, posteromedial, and posterolateral. Composite scores were also derived from those measures. The testing took place prior to the 2009 and 2011 high school football seasons. During those seasons acute lower extremity injuries (LEI) were documented and then compared at the end of the season to determine if there were significant differences between the groups. Results: Forty-one of the 239 athletes experienced a LEI over the course of the 2009 and 2011 seasons. When comparing injured vs. non-injured athletes there was no statistical difference in the anterior reach direction (p = 0.06), posteromedial direction (p = 0.91), posterolateral direction (p = 0.052), or composite score (p = 0.26). However preliminary data showed statistical significance when comparing contact vs. non-contact injuries (p = 0.02). Conclusion: We found that there were no statistically significant differences between athletes who did and did not experience a LEI, therefore the SEBT currently can not be used to predict LEI in high school football players. However our preliminary data shows that the SEBT may be able to predict contact vs. non-contact injuries in high school football players (p = 0.02).

This book was released on 2021 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical activity can promote positive physical changes which, when performed repeatedly, can result in improvements to sport performance. However, activity that is too intense or too frequent may result in potential injury. Reducing injury occurrences and severity has shown to be critical for competitive success. In college football, injury rates have been reported to be 7.14 per 1,000 athlete exposures (AEs), with 35% occurring from a non-contact or overuse cause. A potential contributor to these injuries may be the length and intensity of sport activities that athletes experience following periods of time-off. Another contributor could be the rate that athletes experience this increased activity. In response, sport practitioners have begun measuring athlete activity during training and competition. Research has shown relationships between the amount of activity (workload), the rate of activity exposure, and ensuing non-contact injury. However, these studies have drawn criticism for how these relationships were assessed and the lack of an associated path between activity and injury. In response, the purposes of this dissertation were to 1) utilize modern techniques to assess the relationships among injuries, activity, and rate of activity increase at a particular point of the season between two different teams, 2) determine the non-contact injury rates for each phase of the calendar year and assess the relationship of injury occurrence to activity and activity rates within one team, and 3) to evaluate if inflammation may be a key component on the path between activity and non-contact injuries. Our first study measured workload, workload ratio, and non-contact injuries from two football teams (120 athletes) across two seasons. Both teams observed 44 total non-contact injuries, however the difference in reported injuries which resulted in time-loss from sport (Team 1: 6; Team 2: 17) led us to question if teams used different criteria for removing an athlete from team activities. Teams had different workload and workload ratios in each phase of the year. Our calculations demonstrated that workload and workload ratios were associated with injuries. However increased activity was associated with lower chance of injury, and workload ratios were only associated with a higher chance of injury to a point. These relationships were consistent with our second study, which examined these measures across nearly three years of data from one team (n = 88). The pre-season practice phase was the largest in both workload and time-loss non-contact injury rate (4.70 AEs), however, winter conditioning (2.84 AEs), spring practice (2.64 AEs), and summer conditioning phases (1.42 AEs) had injury rates higher than in-season (1.20 AEs). This suggests the need to monitor these other phases of training. Finally, we assessed C-reactive protein in 19 football players during a pre-season and in-season period to determine if workload and workload ratios led to increased inflammation (CRP), which led to non-contact injury. However, our study showed that CRP did not vary across time and was poorly related to any difference in activity from week to week. However, the observance of only one time-loss non-contact injury limited our findings. Overall, our studies highlight the strengths and weaknesses of the current workload and workload ratio research. Further research should be conducted across multiple teams and years in order to observe enough non-contact injuries to permit the use of certain statistical tools that would be more useful to practitioners and coaches. In addition, further research should continue to see if there is a path between seek to find mediating pathways between activity and injury.

Available in PDF, EPUB and Kindle. Book excerpt: The primary aim of the current project was to investigate the isokinetic muscular strength and performance of elite male youth footballers, and the relationships with age, seasonal variation and injury. A secondary aim was to use the information gathered to target muscle strain injury prevention strategies to particular age groups and times, and evaluate the effect. The primary aim was achieved by establishing normative patterns for muscular strength and performance of elite male youth footballers (grouped according to chronological and biological age) across a competitive season of youth football in Chapters Four and Five. Isokinetic muscular strength (characterised by peak torque (PT) and peak torque relative to body weight (PTBW)) of the hamstrings (H) and quadriceps (Q) using both concentric (CQ, CH) and eccentric muscle actions (EH) was evaluated. Muscular performance of the same muscle groups (characterised by H:Q ratios (conventional (CHQ) functional (FHQ)), asymmetry (dominant (dom):non dominant (ndom) leg ratios (e.g. CQ:CQ)), and angle of peak torque (AoPT)) was also investigated which necessitated an isokinetic speed of 60 °/s. Isokinetic evaluation was completed three times over the course of a regular playing season (start of season (SS) mid season (MS) and end of season (ES)). Participants were grouped according to chronological age (n=152, under 12 (U12) - under 18 (U18)) and biological maturation (according to Pubertal Development Scale (PDS 1 - 5) n=134). Forty seven participants completed SS, MS and ES isokinetic evaluation. Bilateral isokinetic evaluation consisted of five maximal repetitions of CQ and CH, followed by five repetitions of EH, leg dominance was counter-balanced. Repetitions two-four were used to calculate PT, PTBW, dom:ndom and AoPT for CQ, CH and EH, CHQ and FHQ; these measures were compared across chronological and biological age groups using a mixed model ANOVA. Dom:ndom CQ, CH and EH were compared across chronological and biological age groups using a one way ANOVA, while the relationship between AoPT and PT/PTBW was considered using a Pearson's correlation. Additionally, the relationship between chronological and biological age, and PT/PTBW was investigated using a mixed model ANOVA within PDS group three. For analysis of seasonal variation a mixed model ANOVA was applied for all isokinetic measurements which considered time (SS, MS, ES), leg dominance (dom, ndom) and age group (U12 -U15) with a further mixed model ANOVA performed on CQ:CQ, CH:CH and EH:EH. Where appropriate SIDAK corrections were applied and the level of significance was accepted at p≤0.05. The main findings were that youth footballers did not increase their PT and PTBW EH in-line with CQ and CH as chronological and biological ageing progressed, this lead to a significant FHQ imbalance at U18. Dom:ndom CH comparisons identified that the chronologically younger and biologically less developed groups displayed a significantly stronger dom leg which may be explained through the concepts of skill acquisition and trainability. Biological age was not found to exert any additional effect over and above that of chronological ageing as significant differences in muscle strength still existed according to chronological age group within PDS group three. Additionally, AoPT EH and PT EH were found to be significantly negatively correlated on both legs which supported a potential mechanism for non contact hamstring muscle strain injury during running. Analysis of seasonal variation revealed that all PTBW measures showed a MS decrease. This may be related to breaks in normal training activity and links appropriately to times of peak injury incidence highlighted in youth football. In order to achieve the secondary aim of the current project Chapters Four, Five and Six investigated the relationship between isokinetic muscular strength and performance, muscle strain injury of the thigh, and injury risk attenuation. A retrospective and prospective injury audit was undertaken for the elite male youth football participants. For the retrospective approach participants were grouped according to chronological age (n=147) or biological age (n=128) and indicated using a self-report injury form their history (ever, (Hx)) or recent history (12 months, (Hx12)) of hamstring, quadriceps and adductor injuries. Approximately each player had an Hx of muscle strain injury and 0.56-0.59 of players had an Hx12. The hamstrings were the most commonly injured muscle group and the prevalence of muscle strain injury Hx and Hx12 increased with chronological and biological age. The prospective audit (n=50) identified that 0.16 of players sustained a muscle strain injury during the season, 0.08 of these being to the hamstrings. Between group comparisons (one way ANOVA with SIDAK correction) were also performed to investigate the difference in isokinetic measures between those participants who had an Hx12 of muscle strain injury and those who did not. It was discovered that for Hx12 of an injury to the dom hamstrings the injured group had less PTBW CH and EH on the dom leg. The injured group also had more inner range AoPT CH. These findings linked appropriately to the reported mechanisms and risk factors for hamstring injury but the exact direction of cause and effect could not be established. To this end a logistic regression analysis was undertaken in an attempt to predict which group (injured vs. non injured the 50 participants would belong to, using evidenced based risk factors in the experimental model. No predictive relationship between risk factors (including altered isokinetic muscular strength and performance) could be established. The information regarding the relationship between injury and muscular strength and performance may highlight a role for isokinetic screening to ensure adequate rehabilitation from injury. Injury risk attenuation strategies were investigated through an exercise intervention using the U18 age group following a break from football activity. The participants were split based on their FHQ at initial isokinetic evaluation (via odd and even placing) to form control (n=8) and intervention groups (n=8). Isokinetic evaluation was conducted as previously outlined and the exercise intervention targeted the hamstrings. Only six of the control group and seven of the intervention group completed the study and were compared using a mixed model ANOVA. Results showed that the intervention group were not significantly different to the control group post intervention for any of the isokinetic muscular strength and performance measures, though both groups significantly improved over time for the ndom leg CHQ and PTBW EH, and FHQ improved for both legs. Contamination of the control group may explain the lack of significant difference between groups. However, the exercise intervention was not targeted to individuals who displayed prior alterations to isokinetic muscular strength and performance, and this approach was discussed using the results of one member of the intervention group. In summary, the current project achieved the stated aims by discovering normative patterns of isokinetic muscular strength and performance according to age and seasonal variation. Injury risk attenuation strategies were targeted appropriately to the U18 age group following a break from football activity. However, the applied evidence based exercise may have been more effective if targeted to 'risk' after isokinetic screening.

This book was released on 2008-06-17 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, the scientific information on psychology of injury has increased considerably. Despite dramatic advances in physical education of coaches, field of medicine, athletic training, and physical therapy, the sport-related traumatic injuries is our major concern. Athletic injuries, both single and multiple, have a tendency to grow dramatically. Accordingly, prevention of sport-related injuries is a major challenge facing the sport medicine world today. The purpose of this book is to accumulate the latest development in psychological analyses, evaluation, and management of sport-related injuries, including traumatic brain injuries. No two traumatic injuries are alike in mechanism, symptoms, or symptoms resolution. There is still no agreement upon psychological diagnosis and there is no known comprehensive treatment for sport-related injuries for regaining pre-injury status. Physical symptoms resolution is not an indication of "psychological trauma" resolution.
