“…The relationship between physical fitness and musculoskeletal injuries has been investigated in military conscripts 8 10 31. Heir and Eide8 found that aerobic fitness was associated with injury in univariate analysis, but the relation was no longer significant after adjustment for BMI.…”

“…Heir and Eide8 found that aerobic fitness was associated with injury in univariate analysis, but the relation was no longer significant after adjustment for BMI. Finnish military conscripts with an excellent aerobic fitness at baseline had a 30% higher injury risk than poor fitness subjects during a 6- to 12-month follow-up (10, table 3). This is in accord with our results, which suggest that the injury absence risk adjusted for confounders was slightly higher in the high than in the lower fitness categories.…”

“…Analyses were also carried out in diagnostic subgroups. Injury could be associated with high fitness,10 and first absences were divided in injuries (ICPC codes L72–L81, L96) and non-injuries. We restricted the non-injury group to diagnoses of the upper extremity, neck and back (ICPC codes L1–L3, L8–L12, L83–L86, L92, L93), which are most relevant for work-related absence.…”

“…The patients selected for this study comprised of young military trainees who had passed their entry medical examination as healthy and were a�le to perform physically demanding military training. Physical and com�at training includes physical exercise, causing increased loads to the lower lim� and especially to knees �ecause kneeling and crawling are often included in the training activities (15). This training is performed almost daily throughout the service period.…”

Sensitivity of MRI for Articular Cartilage Lesions of the Patellae

Background and Aims: Reliable diagnosis of articular cartilage lesions of the patellae is often based on arthroscopy. however, unnecessary arthroscopies should be avoided. the aim of this study was to assess the sensitivity and applicability of MRi to diagnosing articular cartilage lesions of the patellae.Materials and Methods: We identified 74 consecutive males (mean age 21 years, range 18-28) from the medical records of our institute with the sole diagnosis of articular cartilage lesions of the patellae based on arthroscopy. Magnetic resonance imaging was performed with 1.0 tesla scanner a mean of 4 weeks before arthroscopy. Sensitivity of symptoms, and MRi for the diagnosis was calculated.Results: Based on arthroscopy, 20 (27%) cases of cartilage lesions of the patellae were grade-i, 32 (43%) were grade-ii, and 22 (30%) were grade-iii. MRi revealed cartilage lesions of the patellae in 49 knees (66%), indicating that the sensitivity of MRi was 66% (95% ci: 53%-74%). MRi sensitivity increased with the severity of chondral lesions: all grade iii to iv lesions were detected (sensitivity 100%, 95% ci: 85%-100%) by MRi. grade of articular cartilage lesions of the patellae based on arthroscopy was not associated with clinical symptoms (p = 0.61).Conclusions: the sensitivity of 1.0 tesla MRi for detecting grade-i lesions was low and could not be used to confirm the diagnosis of articular cartilage lesions of the patellae. for the detection of more severe grade-ii to iii lesions, the MRi sensitivity was markedly higher. MRi may thus be considered an accurate diagnostic tool for identifying more severe cases of articular cartilage lesions of the patellae.

“…These include, amongst others: female gender [6-9], Caucasian race [10-12], biomechanical factors such as foot structure and flexibility [1,7,11], previous history of injury, high running mileage, high amount of weekly exercise [3,4,13-17], tobacco use [7,11,18,19] and low levels of physical fitness and activity [3,7,10,14,20-24]. The evidence is contradictory, however, with respect to some factors, including age, foot structure, muscular strength and body composition [3,6,7,11,12,21,24,25].…”

BackgroundMusculoskeletal disorders (MSDs) are the main reason for morbidity during military training. MSDs commonly result in functional impairment leading to premature discharge from military service and disabilities requiring long-term rehabilitation. The purpose of the study was to examine associations between various risk factors and MSDs with special attention to the physical fitness of the conscripts.MethodsTwo successive cohorts of 18 to 28-year-old male conscripts (N = 944, median age 19) were followed for six months. MSDs, including overuse and acute injuries, treated at the garrison clinic were identified and analysed. Associations between MSDs and risk factors were examined by multivariate Cox's proportional hazard models.ResultsDuring the six-month follow-up of two successive cohorts there were 1629 MSDs and 2879 health clinic visits due to MSDs in 944 persons. The event-based incidence rate for MSD was 10.5 (95% confidence interval (CI): 10.0-11.1) per 1000 person-days. Most MSDs were in the lower extremities (65%) followed by the back (18%). The strongest baseline factors associated with MSDs were poor result in the combined outcome of a 12-minute running test and back lift test (hazard ratio (HR) 2.9; 95% CI: 1.9-4.6), high waist circumference (HR 1.7; 95% CI: 1.3-2.2), high body mass index (HR 1.8; 95% CI: 1.3-2.4), poor result in a 12-minute running test (HR 1.6; 95% CI: 1.2-2.2), earlier musculoskeletal symptoms (HR 1.7; 95% CI: 1.3-2.1) and poor school success (educational level and grades combined; HR 2.0; 95% CI: 1.3-3.0). In addition, risk factors of long-term MSDs (≥10 service days lost due to one or several MSDs) were analysed: poor result in a 12-minute running test, earlier musculoskeletal symptoms, high waist circumference, high body mass index, not belonging to a sports club and poor result in the combined outcome of the 12-minute running test and standing long jump test were strongly associated with long-term MSDs.ConclusionsThe majority of the observed risk factors are modifiable and favourable for future interventions. An appropriate intervention based on the present study would improve both aerobic and muscular fitness prior to conscript training. Attention to appropriate waist circumference and body mass index would strengthen the intervention. Effective results from well-planned randomised controlled studies are needed before initiating large-scale prevention programmes in a military environment.

Nature and risk factors of injury hospitalization in young adults: A follow-up of 135,987 military conscripts

Abstract: Women were markedly more likely than men to be hospitalized for injury. Moreover, overweight predicted an increased injury risk. Generalizable to the young adult population, the findings should be considered when identifying targets for injury prevention measures.
