An evaluation of myocardial function is necessary to assess the condition of a patient's heart. Although ejection fraction is used as a measure of myocardial function, many common cardiac illnesses affect the myocardium locally rather than globally. It may therefore be possible to determine the motion of the regional wall of the heart by evaluating myocardial strain. Studying the efficacy of CMR feature tracking in diabetics Type 2 To determine whether the use of MRI feature tracking is effective in detecting myocardial strain deformations in diabetics and healthy individuals. This study involved 80 patients, 40 of whom had Type 2 diabetes and 40 of whom did not, who were subjected to cardiac MRI and echocardiography. Post-processing was done offline using CMR feature tracking and echocardiography speckle tracking, followed by SPSS analysis of the data. T2DM patients and controls did not demonstrate any significant differences in the study. There was a significant decrease in the LV GLS and LV GRS values among T2DM patients (p 0.0001) as compared to normal controls. Where the LV GLS was in controls (-20±5) and diabetes (-15±2). The CMR-FT method is well suited for accommodating STE, providing additional information in clinical trials, which can be used interchangeably. This study recommends that feature tracking (FT-CMR) and speckle tracking echocardiography (STE-Echo) be incorporated into the clinical practices of hail hospitals due to their positive results in diagnosing myocardial deformation.
Background and purpose
The effects of various exercise training programs on balance in older adults are well established. This study aimed to compare the effect of functional-task training with resistance training in improving balance performance in older adults.
Methods
A total of 100 community-dwelling older adults aged 65 years and above were randomly allocated into two groups: functional-task training (FTT) group and resistance training (RT) group. The FTT group (n = 50) performed functional task exercises and the RT group (n = 50) performed resistance exercises three times a week for 12 weeks. Balance was evaluated before and after the trial using the Berg Balance Scale (BBS) and the Timed Up and Go (TUG) test.
Results
A total of 87 subjects who completed the study were analyzed. Both the groups showed a significant change in BBS and TUG test (p < 0.05) from baseline to 12 weeks. However, post-intervention analysis between the groups showed a significant difference in both the BBS and TUG test (p < 0.05), i.e. improvement in the FTT group was better than the RE group at the end of training.
Conclusion
Both the FTT and RT were effective in improving balance. However, the improvement achieved by the FTT group was better than the RT group.
Introduction: Reaction Time (RT) is the time taken by an individual to respond to external stimuli. It is one of the most important determinant ability in sports like Volleyball. Shorter RT leads to higher performance and success in Volleyball. Two types of training methods, massed and distributed practice have been used in researches to improve RT and other sports related skills in sports. In massed practice, there is persistent workout with hardly any rest periods even of minimal time period relative to the work interval while in distributed practice; it is interspersed with rest or other skill learning. There are mixed evidences on effectiveness of these practice methods which has led to the present study. Aim: To find the effect of distributed practice and massed practice in terms of RT among collegiate volleyball players. Materials and Methods: The study design was quasi-experimental pilot study that was conducted at the volleyball academy Gurugram, Haryana, India from September 2019 to December 2019. A total of 30 players, aged 18-22 years, from college volleyball team were invited to participate in the study. Subjects were randomly divided into two groups. Group A received massed practice (n=15), and group B received distributed practice (n=15) for 40 minutes, four days a week for four weeks. Players who were practicing daily for one hour were included in this study and they were excluded if they had any condition that limited their participation in the study or if they are suffering from any type of orthopaedic or neurological illness. RT was measured using Ruler Drop Test (RDT) and Red Light Green Light Test (RLGL). Data was analysed using Statistical Package for the Social Sciences (SPSS) version 20.0 for statistical analysis. Results: The mean pre and post data of Group A, for RDT was 0.16 and 0.12 seconds, respectively; of Group B, it was 0.16 and 0.13. The mean pre and post data of Group A for RLGL was 0.42 and 0.38 seconds, respectively; Group B data for RLGL pre and post was 0.39 and 0.37 seconds, respectively. Both the groups showed significant improvement in scores of RDT (p-value for Group A=0.01, Group B=0.05) and RLGL (p-value for Group A=0.01, Group B=0.01) measured by the paired sample t-test (p<0.05). But there was no significant difference in between group analysis measured by independent sample t-test (p>0.05). Conclusion: This study showed that both massed and distributed practice was helpful in improving RT of collegiate volleyball players. As there was no significant difference between the two groups, consequently which practice method is superior in improving RT in collegiate volleyball players could not be stated.
