032 Does mental fatigue negatively affect functional performance tests used to screen for lower extremity injury risk?

Background: Early identification of the BMI and muscle weakness, can be promoted for developing future rehabilitation by giving proper training in athletes to reduce chance of injuries especially in female athletes. There-for the purpose of this study was to determine the correlation between BMI and hip muscle strength in young female athletes. Materials and Methods: study was conducted among college level female athletes from different colleges of Mangalore, Karnataka, India. 20 college level female athletes between 18-25 years with free from injury and involved at least 2 hrs. per week training session were included in this study. Athletes were excluded if participant had an acute injury during previous six months, had musculoskeletal surgery within the past year. Results: The total number of 20 young female athletes aged between 18- 25 were included in this study. Detailed results enumerated in detail in the results section. Discussion and Conclusion: There was no relationship between BMI and hip muscle strength. Identifying the relationship between BMI and hip muscle strength may help to prevent lower extremity injury risk in female athletes and specific muscle group training can be given as rehabilitation protocol. KEY WORDS: BMI, Hip Muscle Strength, Female Athletes, Lower Extremity Injury.

History Of

Athletes with a history of concussion (HC) are at an increased risk of sustaining lower extremity injuries. It is unclear if these individuals exhibit dynamic postural control deficits associated with lower extremity injury risk. The purpose of this study was to determine if collegiate athletes with a HC demonstrate differences in Y-Balance Test (YBT) performance compared to athletes with no history of concussion (NHC). A total of 116 varsity and club athletes from a Division-I university participated. Forty participants reported a HC (female/male: 31/9, age: 20.0 ± 1.4 years, height: 169.3 ± 13.1 cm, mass: 68.4 ± 14.0 kg) while 76 reported NHC (female/male: 60/16, age: 20.0 ± 1.7 years, height: 168.5 ± 12.9 cm, mass: 68.7 ± 14.6 kg). Individuals with a current concussion or lower extremity injury, or a history of lower extremity surgery were excluded. Participants completed the YBT anterior reach direction barefoot on both limbs. The YBT was completed by maximally reaching anteriorly, maintaining balance, and returning to the starting position without errors. Participants completed 4 practice trials and 3 test trials. Reach distances were averaged and normalized to leg length. Between-limb asymmetry was calculated as the absolute difference between the left and right limbs. Separate independent t-tests examined group differences in normalized reach distances and asymmetry. The proportion of participants in each group with >4 cm of asymmetry was compared using a χ2 test. Alpha was set at 0.05 for all analyses. No group differences were identified in normalized reach distances for the left (HC: 61.4% ± 9.2%, NHC: 60.8% ± 6.2%, p = 0.88, ES = 0.08) or right (HC: 61.4% ± 6.2%, NHC: 60.2% ± 6.8%, p = 0.51, ES = 0.17) limbs. However, a greater proportion of HC participants demonstrated >4 cm asymmetry (HC: 40.0%, NHC: 19.7%; p = 0.02) and these participants exhibited greater asymmetry (HC: 3.87 ± 3.69 cm, NHC: 2.40 ± 2.13 cm, p = 0.03; ES = 0.53). Athletes with a HC exhibited greater asymmetry compared to athletes with NHC. Anterior reach asymmetries of >4 cm are associated with greater lower extremity injury risk. The YBT may provide a clinical technique to further explore the relationship between concussion and lower extremity injury.

Prophylactic Use

Despite the common prophylactic use of rigid orthotics in athletes with flat feet to prevent subsequent injury, there is little scientific data in the literature examining the relationship between pes planus and athletic injuries to the lower extremity. The current prospective study was undertaken to establish what relationship, if any, exists between foot morphology and subsequent lower extremity injury. A total of 196 subjects were enrolled in the study, of which 143 (73%) were male and 53 (27%) were female. Forty-two percent of the participants (83) engaged in contact sports. There were a total of 227 episodes of injury involving the lower extremity. Logistic regression using contact sports, gender, and all of the different foot contact areas that were measured at the beginning of the study was undertaken. Although gender and participation in contact sports was predictive of some lower extremity injuries, the existence of pes planus as measured by medial midfoot contact area as a percentage of total contact area was not a risk factor for any injury of the lower extremity. This study shows that in an athletic population that is representative of collegiate athletics, the existence of flat footedness does not predispose to subsequent lower extremity injury. The routine prophylactic use of orthotics in flat-footed athletes to prevent future injury may therefore not be justified based on the data available.
