Aims The present study was undertaken to compare the efficacy of lumbar core stability training with that of balance training, at improving the balance performance in the recreationally active individuals. Most of the studies to date have been conducted on sporting professionals, whose activity demands are higher than the norm. The present study focuses on the recreationally active population, for which the activity demands are comparatively lesser. Methods Thirty recreationally active subjects (15 males and 15 females) were selected for this study. Subjects were randomly divided into three groups: core stability training group (CSTG), balance training group (BTG), and the control group. All subjects were assessed at baseline, and after six weeks, for balance performance, including static, dynamic and functional balance tests. Data were analyzed by paired t-test, ANOVA, Wilcoxon signed-rank test and Kruksal Wallis test. Findings Both training groups (BTG and CSTG) showed significant (P < 0.05) improvement in balance performance compared to the control group, however the improvement in the mean value for the CSTG was greater than that of the BTG. Conclusions Balance training as well as core stabilization training leads to improvement in static and dynamic balance. However none of these training leads to improvement in the functional balance performance.
Background: At high level of competition, sports require long periods of hard physical work. Each athlete should be able to perform desired actions efficiently, which will not be possible without coordinated activation of muscles in the kinetic chain. EMG studies demonstrate that lumbar paraspinal muscles fatigue is associated with Quadriceps Inhibition (QI), leading to speculation that these changes may not only have adverse effect for athletic performance but also increase the risk of injury in long term. This contrasts the evidence about the influence of fatigue on trunk muscles reflex activity. Method: 37 athletes (men) were recruited from city soccer clubs. The participants performed sub maximal isometric exercise of lower back extensors (Ito’s test) to induce fatigue. The two protocols were a single bout and repeated bouts of Lumbar Extension Isometric Exercise (LEIE). The Agility scores recorded at baseline, after single bout and after repeated bouts of LEIE were compared. Conclusion: The two experimental interventions differently affected the agility performance in the sample. On one hand, single bout intervention led to improved performance, repeated bout intervention resulted in relative deterioration of performance.
Background: The Indian population was placed in social isolation due to spread of corona virus. There was a significant increase of psychological distress and symptoms of mental illness in the general population. The aim of this study was to assess the impact of lockdown on sleep quality among collegiate students during COVID-19 pandemic and help healthcare workers to understand the psychological aspect of lockdown and help the community. Method: It is a cross-sectional survey study. Collegiates were selected for the study. An online questionnaire was sent via email or whatsapp. Data was analyzed and result was obtained. Result: Result showed that 19.1% were having very good sleep quality whereas 12.1% were having bad sleep. Sleep latency was 8.5% participants slept within <15 minutes, 35.5% participants slept within 16 to 30 minutes, 26.2% participants took 31 to 60 minutes whereas 29.8% participants took more than 60 minutes. Sleep efficiency result was: 51.8% participants were having very good sleep efficiency whereas 7.1% were having very bad sleep efficiency. 61.7% participants were having very good sleep duration hours whereas 9.9% participants were having very bad sleep duration hours. 4% to 3% participants did not take sleep medicine in last month whereas 0.7% had taken medication for sleep for more than thrice in a week. 68.8% participants had taken sleep medicine once a week and 26.2% had taken medicine twice a week. 41.1% participants never had day time dysfunction whereas 5.0% participants had day time dysfunction. Conclusion: Lockdown had affected the sleep quality of collegiate students.
Background: Prevention of sports injuries requires a comprehensive analysis of intrinsic and extrinsic factors of injuries in athletes. Pre-participation, evaluation, biomechanical assessment and new technology are helpful in providing useful information about the cause and mechanism of sports injury and strategies for injury prevention. However, there have been only few previous investigations which can conclusively correlate certain foot types with specific knee injury. Objective: To determine any relationship between foot type and ACL injury. Method: A case-control study design was adopted for this clinical study to investigate foot- type as a risk factor for ACL injury. 35 professional football players with a surgical history of ACL reconstruction and 35 professional football players without any history of ACL injury participated in our study. Foot types were determined by measuring their medial longitudinal arch angle and rearfoot-leg eversion angle. Questionnaire which included other variables of ACL injury were filled and analysed to eliminate their interference in this study. Odds ratio was used as reliable statistical tool to estimate the relative risk. Result: There was a significant relationship between pronated foot type as a risk factor for ACL injury. Conclusion: This suggests that pronated foot is a risk factor for ACL injury in football players.
