Investigation of the Effect of Six Weeks Electro Muscle Stimulation Training on Physical Changes in the Sedentary Men and Women

Abstract: The purpose of this study was to investigation of the effect of six weeks electrostimulation training on physical changes in the sedentary men and women. Electro muscle stimulation (EMS), which is applied since the discovery of contraction under the influence of electrical currents, on the purpose of rehabilitation and treatment purposes, has attracted the attention of coaches, athletes and sports scientists as a popular training method over time. In the present research, 6 weeks, 3 days a week and for 25 minutes in a day of EMS machine training program was applied to the sedentary women n=12 and sedentary men n=12 . In order to determine effect of EMS machine training on the physical changes which are body mass, % body fat, fat mass, body mass index, total body water, fat free mass, muscle mass, Tanita (SC-300) Body Composition Analyzer was used as a pre-test and post-test. The results of the Tanita body measurements were analyzed by using SPSS computer program, the standard deviations were calculated, and pre- and post-training statistical paired samples T Test analysis were made. According to SPSS analysis results, there are statistically significant increases in the % body fat, fat mass, soft muscle tissues, extracellular and intracellular liquid weights and cell mass weights (p 0.05). Only EMS training has increased the maximum power associated with sports, due to the increase in the speed of movement. In addition, the stronger long-term effects of EMS training provide new opportunities, as determined by the duration of the training. The right application of full-body EMS training with dynamic exercise movements is a promising combination for power and speed training.

The effects of six-week slow, controlled breathing exercises on heart rate variability in physically active, healthy individuals

Abstract: Background and Study Aim: Heart rate variability (HRV) provides information about sympathetic-parasympathetic balance. The effects of different types of physical exercises on HRV have been investigated so far. The purpose of the current study was to evaluate the chronic effects of six-week slow and controlled breathing exercise on HRV in physically active, healthy adults. Material and Methods: A total of 22 individuals (11 female, 11 male) participated in the study voluntarily. The experimental group (EG) attended to the breathing exercises for 15 minutes per day, three days a week for six weeks. Neither the EG nor the control group (CG) did join in any regular physical activity program during the study. Both groups participated in the HRV measurements before and after the six-week of process. Results: Only the EG showed statistically significant changes in some HRV parameters. The alterations observed in LF:HF ratio, HFnu, and LFnu parameters were to reflect the increase in parasympathetic activity. Although the changes in the other parameters of HRV such as SDNN, SDSD, RMSSD, TP, HF, LF, and VLF were also related to increased vagal activity, these alterations were not significant. However, no significant change was found in the CG. Conclusions: These results show that only the slow, controlled breathing exercises for six weeks could be used to improve parasympathetic activity in physically active individuals. A study could be designed where the duration is kept over 8 weeks, and the effects of physical exercises only, breathing exercises only, and physical + breathing exercises together on HRV are examined.

Investigation of Meaning of Leisure Activities and the Satisfaction with Life of Students in the Faculty of Sport Sciences: An Example of Akdeniz University

Abstract: Aim: It is known that recreational activities have positive effects on people's emotions, thoughts, morale and many other issues. The aim of this study was to measure students’ participation in recreational activities, life satisfaction and the meaning of leisure activities to the students in the Faculty of Sport Sciences at Akdeniz University. Method: A total of 252 students (60.3% male, 39.7% female) participated in the study. As data collection instruments, Turkish version (Koker, 1991) of Life Satisfaction Scale (LSS), which was developed by Diener et al. (1985), and Turkish version (Gurbuz et al., 2007) of Leisure Meanings Inventory (LMI) (Esteve et al., 1999) were used. SPSS Package program was used in the study. ANOVA was used in the data analysis. Findings: According to the findings of Leisure Meanings Inventory by classes, there was a statistically significant difference (p <0.005) among the groups. . This difference appears to be between sophomores and juniors when examined on a class-by-class basis. According to the findings of Leisure Meanings Inventory with regard to departments, it was noted that there was very little difference between them, although there was a difference in the averages. This difference was not statistically significant though. There was no statistically significant difference between groups regarding class and department variables according to the findings of Life Satisfaction Scale. Conclusion: The results of this study showed that there was a significant difference between sophomores and juniors while there was no significant difference between freshmen and seniors according to the LMI averages. There was no significant difference between the mean scores of LSS among the classes.

Integrating Breathing Techniques Into Psychotherapy to Improve HRV: Which Approach Is Best?

Abstract: Introduction Approaches to improve heart rate variability and reduce stress such as breathing retraining are more frequently being integrated into psychotherapy but little research on their effectiveness has been done to date. Specifically, no studies to date have directly compared using a breathing pacer at 6 breaths per minute with compassion focused soothing rhythm breathing. Current study In this randomized controlled experiment, 6 breaths per minute breathing using a pacer was compared with compassion focused soothing rhythm breathing, with a nature video being used as a control group condition. Methods Heart rate variability (HRV) measures were assessed via electrocardiogram (ECG) and respiration belt, and an automated blood pressure machine was used to measure systolic diastolic blood pressure, and heart rate (HR). A total of 96 participants were randomized into the three conditions. Following a 5-min baseline, participants engaged in either 6 breath per minute breathing, soothing rhythm breathing, or watched a nature video for 10 min. To induce a stressful state, participants then wrote for 5 min about a time they felt intensely self-critical. Participants then wrote for 5 min about a time they felt self-compassionate, and the experiment ended with a 10-min recovery period. Results Conditions did not significantly differ at baseline. Overall, HRV, as measured by standard deviation of NN intervals (SDNN), low frequency HRV (LF HRV), and LF/HF ratio, increased during the intervention period, decreased during self-critical writing, and then returned to baseline levels during the recovery period. High frequency HRV (HF HRV) was not impacted by any of the interventions. The participants in the 6 breath per minute pacer condition were unable to consistently breathe at that rate and averaged about 12 breaths per minute. Time by Condition analyses revealed that both the 6 breaths per minute pacer and soothing breathing rhythm conditions lead to significantly higher SDNN than the nature video condition during breathing practice but there were no significant differences between conditions in response to the self-critical and self-compassionate writing or recovery periods. The 6 breath per minute pacer condition demonstrated a higher LF HRV and LF/HF ratio than the soothing rhythm breathing condition, and both intervention conditions had a higher LF HRV and LF/HF ratio than the nature video. Conclusions Although the 6 breath per minute pacer condition participants were not able to breath consistently at the low pace, both the participants attempting to breathe at 6 breaths per minute as well as those in the soothing rhythm breathing condition effectively increased HR variability as measured by SDNN, and attempting to breathe at 6 breaths per minute led to the highest LF HRV and LF/HF ratio. Both breathing approaches impacted HRV more than watching a relaxing nature video and can potentially be used as key adjuncts in psychotherapy to aid in regulating physiological functioning, although it appears that consistent breathing practice would be needed.

Effect of slow breathing exercise on non linear Heart rate variability in transfusion dependent thalassemic patients

Abstract: Background: Nonlinear measure of heart rate variability (HRV) is an emerging tool to detect changes in cardiac autonomic nerve function (CANF) in transfusion dependent thalassemic (TDT) patients. Slow breathing exercise (SBE) can significantly improve HRV in health and various diseases. Objective: To observe the effect of slow breathing exercise (SBE) on non linear measures of HRV in TDT patients. Methods: This prospective interventional study was done in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka in 2018 on 60 male TDT patients aged 15-30 years. Thirty patients received conventional treatment and 30 patients performed slow breathing exercise along with the conventional treatment for 3 months. Age and sex matched 30 healthy control were enrolled. All subjects were followed up at baseline and after 3 months. Non linear (Poincare) HRV parameters were recorded by Power Lab 8/35 AD Instrument, Australia. For statistical analysis paired sample ‘ t’ test and independent sample ‘t’ test were used. Result: SD1, SD2 and SD1/SD2 were found significantly lower in TDT patients compared to healthy control at baseline. After 3 months of slow breathing exercise, significant increment of these parameters occurred with trend of improvement in cardiac autonomic nerve function in this group of patients. Conclusion: Slow breathing exercise may improve cardiac autonomic nerve function and sympathovagal balance in transfusion dependent thalassemic patients.

Effect of Slow Breathing Exercise on Forced Vital Capacity and Forced Expiratory Volume in Patients with Major Depressive Disorder

Abstract: Background: Major Depressive Disorder (MDD) is associated with depressed lung function. Regular practice of slow breathing exercise (SBE) significantly improved lung function in healthy adult subjects. This study aimed to observe the effect of SBE and anti-depressive medication on forced vital capacity (FVC), forced expiratory volume in 1st second (FEV1) and FEV1/FVC% in major depressive disorder Methods: This prospective intervention study was carried out in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka on 60 newly diagnosed MDD female patients aged 20 to 50 years. They were enrolled from the Department of Psychiatry of BSMMU. Age, body mass index (BMI), socioeconomic status and occupation matched 30 apparently healthy females were controls. MDD patients were subdivided into 2 groups. Thirty (30) patients were intervened with slow breathing exercise (SBE) along with anti-depressive medication whereas 30 patients were under antidepressive medication only. All patients were studied at baseline and at the end of 3 months of intervention. FVC, FEV1 and FEV1/FVC% were assessed by a portable digital spirometer. To see the difference independent sample ‘t’ test and paired sample ‘t’test were used as appropriate. Results: FVC, FEV1, FEV1/FVC% were significantly lower (p≤0.001) in all MDD patients at baseline than control. After 3 months of follow-up these values were found significantly improved in patients with slow breathing but no improvement was found in patients treated with only anti-depressive medication. Moreover, these values were found significantly higher in patients with SBE than those of patients under medication only after 3 months of follow-up. Conclusion: Based on the study findings, it may be concluded that SBE may significantly improve depressed lung function of MDD patients whereas anti-depressive medication had no impact on reduced lung function associated with MDD.
