Abstract: Objective: To evaluate the effectiveness of the TheraPoint Focal Pressure Support (TP-FPS) as a non-invasive treatment for pain associated with lateral Epicondylitis (LE). Design: Prospective cohort study. Participants: n = 25 study subjects (20 males and 5 females) ranging in age from 18-65 with pain in one upper limb either dominant (23) or non-dominant (2) associated with lateral epicondylitis for a minimum of six months. Interventions: Study participants were tasked to wear the TP-FPS for 3 hours per day for two weeks except when bathing or during main sleep hours. Outcome measures: Visual analog scale (VAS) pain score pre- and post-treatment period. Results: The combined (male and female) cohort average pre-treatment VAS pain score was 7.44 +/- 0.57. Post-treatment VAS pain score was 1.07 +/- 0.42, with a total reduction of 6.37 points and reached significance with p=0.0005. Male cohort demonstrated an average pre-treatment VAS pain score of 7.45 +/- 0.56. Post-treatment VAS pain score was 1.40 +/- 0.45, with a total reduction of 6.05 points and reached significance with p=0.006. Female cohort displayed an average pre-treatment VAS pain score of 7.40 +/- 1.92. Post-treatment VAS pain score was 1.70 +/- 1.14, with a total reduction of 5.70 and reached significance with p=0.001. No statistically significant difference was observed in the VAS pain score reduction between the male and female groups. Conclusion: The TP-FPS may indeed be a non-invasive therapeutic option for reducing pain associated with lateral epicondylitis.

Abstract: Recent advances in the computing power of modern computers have made computational fluid dynamics studies particularly interesting and feasible. We used the computational fluid dynamics method to solve the physical governing equations of the air flow around balls of popular sports in typical game conditions and investigated their aerodynamics and the flight characteristics. The work presented here describes the construction of the computational fluid dynamics models for a baseball, volleyball and two soccer balls, and the use of these models to analyze the effects of spin rate, surface pattern, and size for their respective sports. The computational results show significant correlations between ball spin rate and the aerodynamics forces, including drag and lift, for soccer ball, baseball and volleyball. For the baseball, the lift and lateral forces are shown to have also been influenced by the lace orientation.

Abstract: The purpose of the study was to analysis of the technique of set shot while attempting free throws with the performance, in relation with time to perform the course and displacement of center of gravity. Sixty National level male basketball players of three different height groups i.e. Group I: 5’5’’ to 5’8’’,Group II: 5’9” to 6’ and Group III: 6’ 1” to 6’4”,(20 in each group) were selected as subjects for the study. The data was obtained from two given positions (i) Moment of stance in set shot and (ii) Moment of release of ball in set shot. Total ten attempts were given and the successful shots marked as score out of ten as criterion measure of performance. Four Digital Video cameras Sony 2100 series were used in order to register the technique of set shot while attempting set shot. The films were analyzed by using standard motion analyzer. With regard to purpose of the study techniques of product moment correlation and analysis of variance were applied. In order to check the significance, level of significance was set at 0.05. It was found that there is significant relationship between the time to perform the course and the performance in set shot of different height group players in basketball and there is no significant relationship found between the displacement of center of gravity and the performance of set shot of different height group players in basketball and therefore, the selected variable puts no impact on the performance of set shot. It was also concluded that Time to perform the course had lowest impact (7%) in the performance. Further it was concluded that displacement of center of gravity was significantly different in first group (5’5’’ to 5’8’’) from the other two groups.

Abstract: Background: The maximum lung function for human being reached around the age of 20-25 years. Studies on lung function indicated a progressive age-related functional change of the respiratory physiology. Regular physical activity throughout the life may delay this deterioration of lung function. Objective of the study: The present study was designed to observe the effect of aging on lung function induced by regular physical activity. Methods: Respiratory function was tested by digital spirometer. 479 persons (Male: 246 and Female: 233) ages between 20-70 years were examined at the department labortory, Jadavpur University, Kolkata. 79 persons were excluded from the study due to acute or chronic respiratory disorders and the history of smoking. All the subject were allotted in the five age category (20-29 yrs; 30-39 yrs;40-49 yrs; 50-59 yrs and 60-70 yrs) to observe the age related changes between the trained (male: 100 and female:100) and untrained (male: 100 and female:100) persons. Mean, Standard deviation and‘t’ test were done to calculate the statistical significance and made a valid conclusion. Result: A slow progressive age related decline were observed in trained group compared to untrained in all the age category for both male and female. Conclusion: From the present study it can be concluded that regular physical activity may delay the age related decline of lung function for all the age groups and promote healthy aging.

Abstract: Previous studies have shown that training guided individually by heart rate variability (HRV) elicits benefits on endurance performance. Meanwhile complex programs, which use HRV assessments to tailor exercise prescriptions to individual needs, are included in portable training computers. However, knowledge on health and fitness benefits of such training programs is still limited. Therefore, the aim of the present study was to investigate effects of HRV-based training included in a portable training computer vs general time-based training on aerobic fitness, half-marathon time as well as mood and mental states. Male (n=10) and female endurance runners (n=10) were recruited and randomly assigned to HRV-based (STAR) and predefined time-based training (TBT). At baseline and after 16 weeks of training an incremental exercise test with spirometry was performed to assess aerobic power. Additionally, mood and mental states were asked. After the training period all subjects took part in a half-marathon. Matched-pairs were selected to compare groups based on similar relative weekly energy expenditure during training. With no differences between groups, STAR and TBT reduced weight (p=0.029), body fat (p=0.002) as well as systolic and diastolic blood pressure (p≤0.001). Maximal oxygen uptake significantly increased from 43.0 ± 8.3 to 46.1 ± 9.0 ml.min-1.kg-1 (p≤0.001) and 43.2 ± 4.8 to 46.7 ± 4.7 ml.min-1.kg-1 (p≤0.001) in STAR and TBT, respectively. Moreover, both groups improved maximal velocity (TBT: 0.81 + 0.40 km.h-1 vs STAR: 0.74 + 0.39 km.h-1; p≤0.001) and completed the half-marathon with similar finish times (01:54:35 ± 00:14:02 [hh:mm:ss] vs. 01:52:42 ± 00:13:45 [hh:mm:ss]; p=0.789). Regarding mood and mental states, no major changes were observed over the training period. In conclusion, both HRV- and time-based training elicited similar improvements in aerobic power and body composition. Consequently, HRV-dependent exercise prescriptions serve as a practical tool for day-to-day periodization of aerobic exercise.

Abstract: Heart rhythm disorders are widely reported as complications of scuba diving but rarely after HBO therapy. We report the case of a professional diver who developed a paroxysmal atrial fibrillation after hyperbaric oxygen therapy as treatment of diving accident. It is a professional diver admitted for the treatment of a cochleovestibular desaturation accident. The initial ECG showed normal sinus rhythm. He received 10 HBO therapy sessions. We discovered a heart rhythm disorder. The ECG showed an atrial fibrillation. Heart rhythm returned to sinus after receiving FLECAIN®. Control ECG after 2 months showed a normal sinus rhythm.
