Background: Work –related musculoskeletal disorders (WRMSD) have been reported very often in various occupations. Laboratory personnel are also exposed to many ergonomic risk factors due to the nature of their work. As their work demands awkward and static postures, high repetition, excessive force, excessive reaching, compression or contact stress, forceful or static exertions, lifting and pinch grip lifting, and repetitive motions, they may be at increased risk for work related musculoskeletal disorder which is often ignored. So the study was aimed at estimating the prevalence of work related musculoskeletal disorders among laboratory professionals. Methods: It was a cross sectional study done on 250 laboratory professionals (lab technicians, pathologists, microbiologists, biochemistry technologist) in Udupi district of Karnataka state and validated questionnaire was used to screen for the symptoms. Data were analyzed using descriptive statistics. Results: Prevalence of musculoskeletal symptoms among laboratory professionals was found to be 21.2%. The neck and lower back are observed to be the most affected with symptoms of pain and discomfort with prevalence of 8% and 6.8% respectively. Conclusion: Medical laboratory professionals are at high risk for the development of MSDs related to cumulative trauma. Thus, laboratory professionals are strongly encouraged to adopt preventive measures before symptoms develop.

The purpose of this study was to observe and report anaerobic power and capacity of football players. The design of this study required participants to perform six sprints each of 35 meter. Thirty six (N=36) male football players between the ages of 17 and 28 years volunteered for this study. The mean age, height and weight of football players was 21±2year, 172±6.81cm and 67.50±9.94Kg respectively. The mean sprint time of 1st,2nd,3rd,4th,5th and 6th sprint of football players was 5.50±0.39 seconds, 5.50±0.55 seconds, 5.57±0.56 seconds, 5.78±0.55 seconds, 5.83±0.59 seconds and 5.88±0.62 seconds respectively. The mean power generated during the 1st, 2nd, 3rd, 4th, 5th and 6th sprints by football players was 506.94±119.65 watts, 522.58±165.63 watts, 490.64±134.88 watts, 443.72±137.38 watts, 438.17±132.76 watts and 422.22±130.16 watts respectively. The maximum power, minimum power, average power and fatigue index of football players was 579.94±147.78watts, 376.00±111.66watts, 470.78±114.76watts and 6.00±3.45 respectively. It was concluded from the results of this study that sprint time increased, power declined with a high fatigue index, the football players may need to focus on improving lactate tolerance and this could be a focus of their training programme.

Objective: Aim of the present study was to find out the efficacy of core strengthening training on hypertrophy of core group of muscles (i.e) transverses abdominis (TA) and multifidus (MF) and on trunk flexor as well as extensor endurance tests in normal healthy low core endurance females. Methodology: Study Design: Single blind randomized control trail. Sample size: Convenient sample of 20 female college students with low core endurance. They divided into two groups. Intervention: Experimental group received six weeks progressive core stabilization exercise while control group received no treatment. Out come measurement: Pre and post reading of right and left side cross sectional area (CSA) of MF at L4 and L5 level and TA using ultra sound image. Flexor and extensor trunk isometric tests were too taken for functional improvement. Statistics: Related t- test were used to compare means within the group and unrelated t-tests were used to compare means between two unrelated groups. The significance level was set at p≤0.05. Results: Prior to the intervention there was no significant difference in CSA between the groups. After 6 weeks there was no significant improvement in control group. In experimental group, after six weeks on and average 35.41% improvement in CSA with MF L4 left being most improved site (53.50%) and TA left being least improved site (9.01%). All improvements are statistically highly significant with p<0.001. When the experimental group post values were compared with control group post values all MF CSA values were statistically highly significant (p<0.001) but TA CSA were not. Conclusion: The present study results supports that 6 weeks progressive core stabilization can be used as prehabilitation to prevent LBP in normal healthy female students.

The purpose of this study was to observe haemodynamic and aerobic fitness profile of football players. Thirty (N=30) male college football players between the age of 17 and 28 years volunteered for this study. The mean age, height and weight of football players was 21±3years, 172.63±8.64cm and 71.56±10.75Kg respectively.The mean resting pulse rate, systolic blood pressure, diastolic blood pressure, pulse pressure, mean arterial pressure, rate pressure product, stroke volume, cardiac output and VO2 max was 69±4beats/minute, 120±3mmHg, 78±3mmHg, 42.07±4.71mmHg, 91.67±2.94 mmHg, 83.06±5.05beats.min-1.mmHg, 57.38±5.65ml/beat, 3.97±0.28 L/minute and 42.60±2.26 ml.kg-1.min-1 respectively. It was concluded from the results of this study that college level football players have less values of haemodynamic and aerobic fitness variables than elite level football players and athletes of other countries. Thus, they may need to focus on improving haemodynamic and aerobic fitness variables and this could be a focus of their training programme.
