Background: The most common problem in female athletes is noncontact lower extremity injuries partly related to proprioception and balance. The aim of this study is comparison of 3 training methods, namely neuromuscular, strength & combined trainings effects on proprioception, and balance in female basketball players.
Methods: The subjects were 42 female basketball athletes with mean age, height and weight of 20.73±1.88 years' 172.47±6.57 cm and 63.54±4.98 kg. The body mass index was (21.36±1.17). 3 experimental and 1 control groups completed 6 weeks and 3 times per week neuromuscular, strength and combined trainings. Knee proprioception was measured by Isokinetic Biodex Dynamometer and functional balance by star excursion balance test before and after training. Repeated measure Anova, Independent sample T test and post hoc test was used to show differences between Grou ps.
Results: Statistical analysis of data revealed a significant difference in knee proprioception and functional balance between the 4 training groups (p<0/05).
The combined trainings followed by neuromuscular trainings in female athletes improved the neuromuscular function.
Conclusion: Prescription of combined trainings and then neuromuscular trainings in female athletes’ trainings can cause improvement in neuromuscular function in female basketball players.

Background: The forward head tilt and round holding of shoulder are the two postural problems, being observed not infrequently in young and middle age people. The present study is aimed at investigating such postural abnormalities in two-age groups of women.Methods: In a relatively randomized sampling, 500 women in two age groups were tested to investigate the incidence of "Forward head" and "Round shoulder" abnormalities. 400 women between the ages of 19-25 (mean 19) years and 100 between 35-50 (mean 40) years were examined for mild, moderate and severe abnormalities. Evaluation of posture was carried out by plumb line. The kyphosis was also documented by a kyphosis goniometer. The subjects were also asked about their back pain, and then correlated with the postures and jobs and sporting activities.Results: There was significant difference between variables of "age" and "round shoulder" (p<0.05), but the relationship between "age" and "forward head" was not significant. (P < 0.05) .Also, a significant correlation was noticed between jobs that are position -dependent and abnormalities and severity of pain with job (p<0.05). The kyphosis angle was higher in older age group. There was also a correlation between the kyphosis angle and pain in inter-scapular region". (r=0.4, p=0.0001)Conclusion: The postural abnormalities of “head tilt” and “round shoulder” are seen in both young and middle -age women. The individuals who do regular exercises have less complaint of pain relative to their postural anomalies. Age and Job are effective elements on incidence of most mentioned postural abnormalities in older subjects.
