Relationship between injuries and motivation in recreational runners

Introduction: In recent years, running has become a popular form of recreational sports activity for adults. This study explores the relationships between motivation and injury among recreational runners, a growing population influenced by societal trends in health and wellness. Methods: The study involved 104 participants, consisting of 74 women and 75 men. Among them, 67 were part of a ‘running school’ program, while the remaining 73 were individual runners who trained independently without the guidance of a coach. The Behavioral Regulation in Exercise Questionnaire (BREQ-2) and the Oslo Sports Trauma Research Center (OSTRC) Questionnaire on Health Problems, which is based on the OSTRC Overuse Injury Questionnaire, were used for the research. Results: The study found that pelvic injury was more severe in male participants, while women tended to experience serious back injuries that required them to take a break from training. All participants demonstrated high levels of intrinsic motivation. Multiple regression analysis revealed a positive correlation between injuries and intrinsic motivation in women, whereas in men, there was a negative correlation with introjected regulation. Conclusion: The ‘running school’ participants showed a negative association between injury and external regulation compared to individual runners, where amotivation and injury were positively associated.

Slovenian Translation, Cross-Cultural Adaptation, and Content Validation of the Updated Oslo Sports Trauma Research Center Questionnaire on Health Problems (OSTRC-H2).

The updated Oslo Sports Trauma Research Questionnaire on Health Problems (OSTRC-H2) has been translated into a limited set of languages and lacks full validation of its new measures. To (1) translate, cross-culturally adapt, and evaluate the measurement properties of the OSTRC-H2 for the Slovenian population and (2) investigate the construct validity for the severity score and time lost due to a health problem. Cohort study (diagnosis); Level of evidence, 3. The OSTRC-H2 was translated from English to Slovenian (OSTRC-H2-SLO) according to international guidelines. A 15-week study was conducted among 188 elite athletes, with a test-retest performed in the 10th week. Internal consistency, reliability, content validity, feasibility, and potential ceiling effects were investigated. Internal consistency was measured using the Cronbach alpha coefficient, while reliability was measured with the intraclass correlation coefficient (ICC). Construct validity was measured with the Spearman rank correlation coefficient (r S). There was a 95% response rate and an 18% mean weekly prevalence of health problems. The OSTRC-H2-SLO showed excellent test-retest reliability (ICC, 0.94 [95% CI, 0.67-0.99]), with a Cronbach α of .93. A strong positive correlation was found between the OSTRC-H2-SLO severity score and days lost due to an acute injury (r S = 0.754), overuse injury (r S = 0.785), and illness (r S = 0.894) (P < .001 for all). Moderate to strong negative correlations were observed between severity score and total load (training and competition load in hours) as well as between days lost and total load (P < .001 for all). The OSTRC-H2-SLO was found to be valid, reliable, and well accepted among Slovenian athletes. The authors confirmed the questionnaire's construct validity and identified total load as an indicator of an increase in the severity score. NCT05471297 (ClinicalTrials.gov identifier).

Metabolic Phenotyping from Whole-Blood Responses to a Standardized Exercise Test May Discriminate for Physiological, Performance, and Illness Outcomes: A Pilot Study in Highly-Trained Cross-Country Skiers

BackgroundThis study used metabolic phenotyping to explore the responses of highly-trained cross-country skiers to a standardized exercise test, which was part of the athletes’ routine testing, and determine whether metabolic phenotyping could discriminate specific physiological, performance, and illness characteristics.MethodsTwenty-three highly-trained cross-country skiers (10 women and 13 men) participated in this study. Capillary whole-blood samples were collected before (at rest) and 2.5 min after (post-exercise) a roller-ski treadmill test consisting of 5–6 × 4-min submaximal stages followed by a self-paced time trial (~ 3 min) and analyzed using mass spectrometry. Performance level was defined by International Ski Federation distance and sprint rankings. Illness data were collected prospectively for 33 weeks using the Oslo Sports Trauma Research Center Questionnaire on Health Problems. Orthogonal partial least squares-discriminant analyses (OPLS-DA) followed by enrichment analyses were used to identify metabolic phenotypes of athlete groups with specific physiological, performance, and illness characteristics.ResultsBlood metabolite phenotypes were significantly different after the standardized exercise test compared to rest for metabolites involved in energy, purine, and nucleotide metabolism (all OPLS-DA p < 0.001). Acute changes in the metabolic phenotype from rest to post-exercise could discriminate athletes with: (1) higher vs. lower peak blood lactate concentrations; (2) superior vs. inferior performance levels in sprint skiing, and (3) ≥ 2 vs. ≤ 1 self-reported illness episodes in the 33-week study period (all p < 0.05). The most important metabolites contributing to the distinction of groups according to (1) post-exercise blood lactate concentrations, (2) sprint performance, and (3) illness frequency were: (1) inosine, hypoxanthine, and deoxycholic acid, (2) sorbitol, adenosine monophosphate, and 2-hydroxyleuroylcarnitine, and (3) glucose-6-phosphate, squalene, and deoxycholic acid, respectively.ConclusionMetabolic phenotyping discriminated between athlete groups with higher vs. lower post-exercise blood lactate concentrations, superior vs. inferior sprint skiing performance, and more vs. less self-reported illnesses. While the biological relevance of the identified biomarkers requires validation in future research, metabolic phenotyping shows promise as a tool for routine monitoring of highly-trained endurance athletes.

Malay Translation and Validation of the Oslo Sports Trauma Research Center Questionnaire on Health Problems.

The Oslo Sports Trauma Research Center Questionnaire on Health Problems (OSTRC-H) is a proven surveillance method to register acute injury, overuse injury, or illness in athletes. However, it has not yet been translated into Malay. To translate, culturally adapt, and validate the OSTRC-H into Malay using internationally established guidelines. Cohort study (diagnosis); Level of evidence, 3. The Malay translation of the OSTRC-H (OSTRC-H.M) was distributed to 54 elite (ie, professional) and recreational athletes. Face validity, content validity, and construct validity were assessed for the validity measurement properties, while test-retest and internal consistency were used for reliability measurement properties. The content validity index was satisfactory at 0.93. The OSTRC-H.M showed good internal consistency, with a Cronbach α value of .84. Confirmatory factor analysis showed a good model for construct validity, with values of 0.99 and 0.04 for comparative fit index and root mean square error of approximation, respectively. Per-item intraclass correlation coefficients (ICCs) for test-retest reliability ranged from 0.55 to 0.80. The overall test-retest reliability of the questionnaire was good (ICC, 0.8; 95% CI, 0.63-0.88; P < .001). The OSTRC-H.M was found to be valid and reliable and therefore acceptable for application among Malay-speaking athletes.

Injury Prevalence Among Elite Adolescent Ballet Dancers is not Affected by Frequency of Questionnaire Administration: A 6-Month Exploratory Prospective Study.

The Oslo Sports Trauma Research Centre Questionnaire on Health Problems (OSTRC-H) is a valid and reliable registration method for self-reported injuries and is regularly used among dancer populations. Monthly questionnaire administration is acceptable in athlete populations but has not been evaluated in dancers. The aim of this exploratory study was to assess the influence of weekly versus monthly administration of the OSTRC-H on estimated injury outcomes among elite adolescent ballet dancers. Participants (n = 103) were prospectively followed for 6 months and completed the OSTRC-H online, evaluating perceived consequences of self-reported health problems during the previous week and the previous 4 weeks, respectively. Four definitions of dance-related injury were utilized: (1) all complaints, (2) substantial, (3) medical attention, and (4) time-loss injuries. Descriptive statistics estimated: (1) the number of injuries reported (count), (2) average injury prevalence [proportion, 95% confidence intervals (CI)], (3) average severity score (0-100), and (4) days of time loss (count) for each injury definition. The 4 outcome measures were then compared between weekly and monthly registration with paired sample t-tests (P < .05) and overlapping 95% CI. A significant difference between the number of all complaints injuries (weekly: 133; monthly: 94; P < .001) and substantial injuries (weekly: 64; monthly: 45; P = .012) was found. Regardless of injury definition, there were no significant differences between injury prevalence, severity scores, and days of time loss when reported weekly versus monthly. Monthly administration of the OSTRC-H is an acceptable method to estimate injury prevalence, severity scores, and days of time loss amongst elite adolescent ballet dancers.

Adaptation of the Oslo Sports Injury and Health Problems Questionnaire to the Bahasa Version and Its Application for Athletes Surveillance

The Oslo Sports Trauma Research Center (OSTRC) questionnaire on injuries and health problems is one of the recommended methods for monitoring athletes’ health problems, but until now it has not been available and validated in a Bahasa version. This study aims to develop the OSTRC Questionnaire into Bahasa and assess its application in adolescent athlete surveillance. The research process is divided into two stages; The adaptation and validity assessment according to ISPOR rules involving 42 adolescent athletes for 2 weeks and the second stage is 8 weeks of surveillance involving 46 adolescent athletes. Results of the analysis found that the Bahasa version of the OSLO Questionnaire for shoulder, knee, ankle, and health problems has good validity and reliability with Cronbach-α 0.905, 0.940, 0.933, and 0.840 respectively. The intraclass correlation coefficient for health problems was 0.905, the shoulder region was 0.94, the knee region was 0.933 and the ankle region was 0.840, with all p-values &lt;0.001. The sensitivity of the health problems questionnaire reached 97.6% and specificity 99.4%, while the sensitivity of the injury questionnaire reached 100% and specificity reached 99.4%. The Bahasa version of OSLO Sports Trauma Research Center Injury and Health Problems is valid and reliable and shows high sensitivity and specificity to detect and separate athletes with injuries or health problems.

Groin injuries in women's premier league football in Norway: A two-season prospective cohort study describing clinical and imaging characteristics.

To describe the prevalence, incidence, and burden of groin injuries in the Norwegian women's premier football league and to describe their clinical and imaging characteristics. During the 2020 and 2021 seasons, players in the Norwegian women's premier league reported groin injuries weekly, using the Oslo Sports Trauma Research Centre Questionnaire on Health Problems (OSTRC-H2). We calculated weekly prevalence, incidence, and burden of groin injuries. The team physical therapists classified the player-reported injuries based on the Doha classification system. Injuries with more than 3 days' time loss or reported in 2 consecutive weeks were eligible for magnetic resonance imaging (MRI). On average, 3.9% (95% CI: 3.4-4.4) of players reported a groin injury at any time; of which 78% caused time loss. The incidence rate was 1.6 injuries/1000 h (95% CI: 1.3-2.0) and their burden was 11 days lost/1000 h. The physical therapists examined 67 of 124 player-reported groin injuries (53%). Adductor-related injury was most common (55%) followed by iliopsoas (15%) and rectus femoris-related (12%). Pubic-related injuries caused most time loss (median: 24 days, IQR: 5-133). In this study, 42 injuries were investigated with MRI; 8 (19%) showed no changes, 6 (14%) an acute musculotendinous lesion, and 32 (76%) a nonacute finding (e.g., central symphyseal disc protrusion, tendinopathies). The incidence rate and burden of groin injuries were high. Adductor-related injuries were most common, but pubic-related injuries caused most time loss. Most MRI examinations demonstrated nonacute findings.

Development and Feasibility of an Adolescent Dancer Screen.

Adolescent dancers are at high risk for injuries due to the physical demands of dance training and the physiological changes that occur during adolescence. Though studies report high injury rates, there are few standardized screening tools available for adolescent dancers. To develop and describe a standardized, feasible, evidence-based, and clinically relevant screen for adolescent dancers. Descriptive Epidemiology Study. Dancers at two suburban pre-professional dance studios, in two cohorts, participated in the Columbia Adolescent Dancer Screen (CADS) that includes dance injury history, health questionnaires (EAT-26, SF-36, DFOS), aerobic capacity, range of motion, strength, balance/orthopedic special tests, and dance technique. Participants were asked to complete a weekly injury surveillance questionnaire derived from the Dance-Specific Oslo Sports Trauma Research Centre Questionnaire on Health Problems for 14 weeks following the screening. Feasibility was assessed using process and content analysis in four areas: practicality, demand, implementation, and adaptation. Descriptive data were collected from 32 female dancers aged 11-17 with cohort one averaging 18.57 dance hours per week and cohort two averaging 10.6 dance hours per week. The screen was practical, able to screen seven to eight dancers per hour utilizing nine assessors and requiring a one-hour commitment from dancers. Cost and space requirements were considered and kept to a minimum while utilizing portable equipment. All screening slots were filled with all dancers agreeing to follow-up injury surveillance, indicating high demand. The screen was implemented with two cohorts with revisions to improve efficiency applied for the second cohort. The CADS is a feasible screening tool for adolescent dancers that overcomes barriers by being pragmatic, evidence-based, and efficient. Screening can be implemented to obtain baseline values, inform wellness recommendations, and establish relationships with medical professionals. Level 3b.

Musculoskeletal Injuries in Police Enforcement Trainees in the Pre-service Training Course of Iran

Purpose: Intensive military training courses are among the programs and specialties of the police force. Musculoskeletal disorders in the military are one of the vital factors that keep people away from courses and shorten their service life. This research aims to measure the prevalence of musculoskeletal injuries in newly arrived students in the pre-service training course of the police force using the Oslo Sports Trauma Research Center (OSTRC) questionnaire. Methods: For this purpose, 124 soldiers with a mean age of 20.7 years, a mean height of 178.5 cm, a mean weight of 72.9 kg, and a mean activity per week for 3 hours and 19 minutes in one of the training barracks affiliated to the Tehran Police Force and were selected and completed the OSTRC questionnaire every month for 6 months. The research design of this study is epidemiology and the results are presented descriptively. Results: The results of the research related to prevalence measurement on a monthly mean showed that ankles at 2.8%, knees at 2.2%, and waist at 1.8% respectively have the highest prevalence rates among soldiers. Also, among the harmful factors, the parade had the largest share with 22.5% and during 6 months, the second month had the highest number of injuries, and the sixth month had the lowest number of injuries. In terms of participation in exercises, 86.6% of soldiers participated in practical classes without any physical injuries during the six months. A total of 9.1% of the soldiers could not perform optimally and properly despite their full attendance in the practical classes due to physical injuries and finally, 3.8% of the participants, despite attending the practical classes, had to leave the class halfway due to the severity of the injury. Conclusion: What is clear is that the most affected areas are the central area and the lower limbs, and the spine of the back, head, neck, and upper limbs were not among the most damaged areas. Finally, it seems that the prevalence rate among the soldiers in training courses is acceptable and close to the average of global statistics. However, it is required to take preventive measures as well as plan to add classes and specialized exercises to strengthen physical fitness and specialized exercises related to improving the conditions of damaged areas.

Prevalence and incidence of health problems and their characteristics in Brazilian para athletes: A one-season single-center prospective pilot study

BackgroundPara athletes experience high prevalence and incidence of health problems related to sport. Despite this, there are few longitudinal studies. ObjectiveTo describe the characteristics, prevalence, incidence, and severity of health problems in para athletes from one of the Brazilian Paralympic Reference Centers during a sports season and to compare the prevalence of health problems between para athletics, para powerlifting, and para swimming. MethodsThis prospective pilot study was conducted from October 2019 to March 2020. The Oslo Sports Trauma Research Center Questionnaire on Health Problems was used to record injuries and illnesses every week for 24 weeks. The characteristics, prevalence, incidence, and severity of health problems were described for each modality. The prevalence of health problems was compared among the three sport modalities. ResultsThirty-five para athletes participated. Most of the injuries occurred in the shoulder, and most illnesses caused respiratory and gastrointestinal symptoms. The average weekly prevalence and the incidence rate of health problems were 40.6% (95% CI 17.0–64.4) and 12.7 (95% CI 9.6–15.9) per 1000 athlete hours, respectively. Para powerlifting had the highest prevalence of all and substantial health problems; para swimming had the lowest prevalence of injuries; and para athletics had the lowest prevalence of illnesses. ConclusionsThis group of Brazilian para athletes showed a high prevalence and incidence of health problems throughout the season. Para athletics, para powerlifting, and para swimming each had a different prevalence of injuries and illnesses.

Previous Injury and Lower Well-being Increase Injury Risk in Female Adolescent Athletes.

Several risk factors for injury have been suggested in female elite athletes. However, there is a lack of prospective studies in young female athletes where multiple risk factors have been studied. The aim of this study was to identify risk factors for injury in female adolescent elite athletes. Substantial injuries were monitored in 222 athletes using the validated Oslo Sports Trauma Research Centre Questionnaire over 20 weeks. Over 20 potential risk factors were explored. Based on a binomial generalized linear mixed model, two significant (p<0.05) risk factors for injury were identified; previous injury within the last 12 months (OR 2.55) and well-being (OR 0.97). An athlete with a previous injury had twice as high a risk of injury (13% vs. 6%) compared to an athlete with no previous injury. Higher perceived well-being was associated with a decreased risk of injury. Based on a prospective design with a large sample of female adolescent elite athletes, investigating over 20 potential risk factors for injury, our results suggest that a previous injury and well-being are risk factors for injury.

Epidemiology of injuries and illnesses in elite wheelchair basketball players over a whole season – a prospective cohort study

BackgroundWheelchair basketball is an adaptation of pedestrian basketball and one of the most popular Paralympic sports worldwide. The epidemiology of health problems in wheelchair basketball has been prospectively studied only during the Paralympic Games, the 2018 World Championships, the 2021 South America Wheelchair Basketball Championship, and one season of two American intercollegiate wheelchair basketball teams. The objective of the study was to prospectively monitor and analyze the prevalence, incidence, burden, and characteristics of injuries and illnesses in a wheelchair basketball league during an entire season for the first time.MethodsAll players of the highest German wheelchair basketball league (Bundesliga) were invited to participate in the study. Included players completed the Oslo Sports Trauma Research Center Questionnaire once a week during the entire season 2020/21 to report health problems. Exposure was captured by self-reported training time and officially-recorded competition time.ResultsSixty of 117 players (51%, 47 male, 13 female) of the national league participated with an average response of 93%. Seventy health problems (5.5/1000 exposure hours [95% CI: 4.9–6.1]) were reported, including 54 injuries and 16 illnesses. Prevalence of health problems was 60% (95% CI: 48–72). Most injuries affected the shoulder (32% of all injuries), cervical spine/neck (17%), and hand (13%). More overuse injuries (2.9/1000 exposure hours [95% CI: 2.5–3.3]) than acute injuries (1.3/1000 exposure hours [95% CI: 1.0-1.6]) occurred. Of all health problems, 53% were associated with time-loss. The incidences of all health problems, illnesses, injuries, and overuse injuries were higher in women than in men.ConclusionsCharacteristics and frequency of injuries and illnesses during wheelchair basketball season differed from those during major wheelchair basketball tournaments. The high proportion of overuse injuries and the higher injury rates in women should be regarded in the development of individualized prevention measures. Since results from previous studies during major tournaments are only partially comparable to wheelchair basketball league play, further studies should follow.

The effect of progressive and individualised sport-specific training on the prevalence of injury in football and handball student athletes: a randomised controlled trial.

To evaluate the effectiveness of communication and coordination combined with designing a progressive and individualised sport-specific training program for reducing injury prevalence in youth female and male football and handball players transitioning to a sports academy high school. An additional aim was to investigate the characteristics of the reported injuries. Forty-two Norwegian athletes were randomised into an intervention or control group. Mean age, height, weight and BMI was 15.5 ± 0.5 years, 178.6 cm ± 6.3 cm, 71.3 ± 9.8 kg, 22.3 ± 2.7 BMI for the intervention group (IG) (n = 23), and 15.4 ± 0.5 years, 175.6 cm ± 6.6 cm, 67.1 ± 9.8 kg, 21.7 ± 2.4 BMI for the control group (CG) (n = 19). During the summer holiday, the intervention group received weekly progressive, individualised sport-specific training programs and weekly follow-up telephone calls from the researchers. All athletes completed a baseline questionnaire and a physical test battery. Training data and injuries were recorded prospectively for 22 weeks using the Oslo Sports Trauma Research Center Questionnaire on Health Problems (OSTRC-H2). A two-way chi-square (χ2) test of independence was conducted to examine the relationship between groups and injury. Average weekly prevalence of all injuries was 11% (95% CI: 8%-14%) in IG and 19% (95% CI: 13%-26%) in CG. Average weekly prevalence of substantial injuries was 7% (95% CI: 3%-10%) in IG and 10% (95% CI: 6%-13%) in CG. The between-group difference in injuries was significant: χ2 (1, N = 375) = 4.865, p = .031, φ = .114, with 1.8 times higher injury risk in CG vs. IG during the first 12 weeks after enrolment. For student athletes transitioning to a sports academy high school, progressive individualised, sport-specific training programs reduced the prevalence of all-complaint injuries following enrolment. Clubs and schools should prioritise time and resources to implement similar interventions in periods where student athletes have less supervision, such as the summer holidays, to facilitate an optimal transition to a sports academy high school.

French Translation and Validation of the OSTRC-H2 Questionnaire on Overuse Injuries and Health Problems in Elite Athletes.

To evaluate the burden of overuse injuries, the Oslo Sports Trauma Research Centre (OSTRC) questionnaire on health problems (OSTRC-H2) was developed in English in 2013. To translate and culturally adapt the OSTRC-H2 into French and investigate the reliability and validity of this new version. Cohort study (diagnosis); Level of evidence, 3. The OSTRC-H2 was translated from English to French according to international guidelines. A total of 80 elite athletes were then invited to complete the OSTRC-H2 weekly for 3 months. Potential ceiling effects, construct validity, and reliability were investigated. Convergent validity was measured using Pearson correlations for continuous items and kappa coefficients for binary items; internal consistency was measured using the Cronbach alpha coefficient; and test-retest reliability was measured using the intraclass correlation coefficient (ICC). Separate analyses were performed on the entire cohort of athletes (population 1 [P1]) and on athletes who reported a health problem during the follow-up (P2). A total of 80 elite athletes took part in this study. The response rate was very high, with 909 of 960 questionnaires returned (95%). The mean weekly prevalence of health problems was 19.6% during the follow-up period. Nineteen participants reported a health problem during the follow-up (P2). The OSTRC-H2 showed very good test-retest reliability for both populations (ICC, 0.85 [95% CI, 0.77-0.90] for P1; ICC, 0.90 [95% CI, 0.68-0.98] for P2). Internal consistency was very good for P2 (Cronbach α = .94). The OSTRC-H2 demonstrated high concordance with the visual analog scale of symptom intensity (r = 0.52; P < .05), and low concordance with the overtraining questions from the Questionnaire de la Société Française de Médecine du Sport (κ from -0.01 to 0.12; P > .05). The French version of the OSTRC-H2 was found to be valid and reliable when applied to French-speaking elite athletes.
