The Effects of Yoga and Aerobic Exercise on Concentration and Feeling-States

The impacts of yoga and aerobic exercise on level of concentration and change in feeling-states were examined in this study. They hypothesis was that concentration and feeling-states would improve over a yoga and aerobic exercise session, but yoga, a combination of exercise and meditation, was expected to produce greater positive changes than aerobic exercise. Participants included 70 students from Roger Williams University, 27 male and 43 female. 34 took part in 30 minutes of yoga and 36 took part in 30 minutes of aerobic exercise. Concentration levels and feeling-states improved significantly over sessions of both yoga and aerobic exercise sessions equally. Results indicate that aerobic exercise and yoga both produce positive changes in concentration, stress, energy, and well-being while only yoga produces improvements in mood and self-satisfaction

PENGARUH LATIHAN AEROBIK DAN ANAEROBIK TERHADAP AMBANG ANAEROBIK

This research is aimed at demonstrating: 1) the effects of aerobic exercise towards the increase of anaerobic threshold, 2) the effects of anaerobic exercise towards the anaerobic threshold, 3) the difference in effectiveness of aerobic and anaerobic exercise towards anaerobic threshold. This is an experimental study using Pretest – Posttest Group Design. The populations involved in this study were 21 volleyball players of GARUDA from Kulonprogo regency, Yogyakarta. The samples were all players of the population so that it is categorized as population research. The samples were divided into two experimental groups which were aerobic and anaerobic groups using ordinal-pairing approach. The variables were: 1) independent variables: Aerobic and Anaerobic Exercises, 2) the dependant variable: anaerobic threshold. To determine anaerobic threshold, the researcher used running tests from Janssen (1989). The data were analyzed using T-test and mean variation. The results of normality tests using Kolmogorov Smirnov for aerobic exercise, Z count 0.513 P = 0.955, the status of spreading was normal while Z count for anaerobic exercise was 0.625 p = 0.829, the status of spreading was normal. Homogeneity tests using F-tests resulted in F = 0.003, P = 0.959, meaning that the variance of the samples was homogenous. The hypothesis test to experimental group I which was the group of aerobic exercise resulted in t count = -16.686, p = 0.000 which implied that there was significant influence of aerobic exercise towards anaerobic threshold and one to experimental group II which was the group of aerobic exercise resulted in t count = -16.754, p = 0.000 which implied that there was significant influence of aerobic exercise towards anaerobic threshold. The mean pre-test was 58.55, Post-test was 167.557, so that the mean difference was 9. For the anaerobic exercise, the mean of Pre-test was 158.80 and Post-test was 163,30, so that the mean difference was 4.50. Thus, the aerobic exercise had bigger mean differences than anaerobic exercise which implies that aerobic exercise was more effective than anaerobic in relation to the capacity of anaerobic threshold.

Does Aerobic Exercise Increase 24-Hour Ambulatory Blood Pressure Among Workers With High Occupational Physical Activity?-A RCT.

ObjectiveHigh occupational physical activity (OPA) increases cardiovascular risk and aerobic exercise has been recommended for reducing this risk. This paper investigates the effects of an aerobic exercise intervention on 24-hour ambulatory blood pressure (ABP) among cleaners with high OPA.MethodsHundred and sixteen cleaners between 18 and 65 years were randomized. During the 4-month intervention period, the aerobic exercise group (AE) (n = 57) performed worksite aerobic exercise (2 × 30 minutes/week), while the reference group (REF) (n = 59) attended lectures. Between-group differences in 4-month ABP changes were evaluated by intention-to-treat analysis using a repeated-measure 2 × 2 multiadjusted mixed-models design.ResultsRelative to REF, 24-hour ABP significantly increased in AE: systolic 3.6 mm Hg (95% confidence interval (CI) 1.6-5.7) and diastolic 2.3 mm Hg (95% CI 0.9-3.8). Cleaners with high aerobic workload exhibited particularly high 24-hour ABP increases: systolic 6.0 mm Hg (95% CI 2.4-9.6), and diastolic 3.8 mm Hg (95% CI 1.3-6.4).ConclusionAerobic exercise increased 24-hour ABP among cleaners. This adverse effect raises questions about the safety and intended benefits of aerobic exercise, especially among workers with high OPA and a demanding aerobic workload. http://www.controlled-trials.com/ISRCTN86682076.

Effects of exercise modalities on arterial stiffness and wave reflection: a systematic review and meta-analysis of randomized controlled trials

Background and Objectives: Physical activity is associated with lower cardiovascular and all-cause mortality. However, the effects of different exercise modalities on arterial stiffness are currently unclear. Our objectives were to investigate the effects of exercise modalities (aerobic, resistance or combined) on pulse wave velocity (PWV) and augmentation index (AIx), and to determine whether the effects on these indices differed according to the participants' or exercise characteristics. Methods: We searched the Medline, Embase and Cochrane Library databases from inception until April 2014 for randomized controlled trials lasting ≥4 weeks investigating the effects of exercise modalities on PWV and AIx in adults aged ≥18 years. Results: Forty-two studies (1627 participants) were included in this analysis. Aerobic exercise improved both PWV (WMD: −0.63 m/s, 95% CI: −0.90, −0.35) and AIx (WMD:−2.63%, 95% CI: −5.25 to −0.02) significantly. Aerobic exercise training showed significantly greater reduction in brachial-ankle (WMD: −1.01 m/s, 95% CI: −1.57, −0.44) than in carotid-femoral (WMD: -0.39 m/s, 95% CI: −0.52, −0.27) PWV. Higher aerobic exercise intensity was associated with larger reductions in AIx (β: −1.55%, CI −3.09, 0.0001). In addition, aerobic exercise had a significantly larger effect in reducing PWV (WMD:−1.0 m/s, 95% CI: −1.43, −0.57) in participants with stiffer arteries (PWV ≥8 m/s). Resistance exercise had no effect on PWV and AIx. There was no significant effect of combined exercise on PWV and AIx. Conclusions: We conclude that aerobic exercise improved arterial stiffness significantly and that the effect was enhanced with higher aerobic exercise intensity and in participants with greater arterial stiffness at baseline.

The repeatability of the abbreviated (4-h) Oral Fat Tolerance Test and influence of prior acute aerobic exercise

© 2016 The Author(s) Purpose: The Oral Fat Tolerance Test (OFTT) is regarded as a repeatable measure used to assess postprandial triglyceride (TAG) levels, with higher levels observed in cardio-metabolic disorders. Acute aerobic exercise intervention before OFTT reduces the TAG response, but the repeatability of this effect is unknown. The aim of this study was to determine the repeatability of the abbreviated 4-h OFTT with and without immediate prior aerobic exercise. Methods: On four separate days, healthy adult male participants underwent two 4-h OFTT (n = 10) and another two 4-h OFTT with 1-h of standardised moderate intensity aerobic exercise performed immediately before meal ingestion (n = 11). The OFTT meal composition included 75.4 g total fat, 21.7 g carbohydrate and 13.7 g protein. Venous blood was sampled at baseline and hourly up to 4 h after the OFTT meal ingestion, and TAG area under the curve (AUC) was calculated. Results: Nonparametric Bland–Altman analysis of 4-h TAG AUC revealed that 9 of 10 repeat measurements fell within ±15 % of the median TAG AUC for the OFTT. By contrast, two of 11 repeat measurements fell within ±15 % of the median TAG AUC for the OFTT undertaken with 1-h prior aerobic exercise. Conclusions: The 4-h OFTT is a repeatable test of postprandial TAG responses in healthy men. However, aerobic exercise performed immediately before OFTT considerably increases the variability of TAG AUC. These findings have implications for interpretation of research studies investigating exercise intervention performed immediately before OFTT. Future studies should also investigate the repeatability of exercise performed 8–24 h before OFTT

The Effects of Aerobic Exercise on NF-κB and TNF-α in Lung Tissue of Male Rat

Background:Regular aerobic exercise improves theBackground: Regular aerobic exercise improves the inflammatory status in different lung diseases. However, the effects of long-term aerobic exercise on the lung response have not been investigated. The present study evaluated the effect of aerobic exercise on the lung inflammatory.Materials and Methods: 12 adult male Wistar rats were divided to 2 groups: A: control (n=6), B: aerobic exercise (five times per week for 4 week; n=6). The gene expression of NF-κB and TNF-α were analyzed in lung tissue by Real time–PCR. In order to determine the significant differences between groups independent t-test were used.Results: Aerobic exercise inhibited the gene expression of NF-κB and TNF-α. But there was no significant difference between A and B groups for TNF-α and NF-κB.Conclusion: We conclude that four week aerobic exercise decrease inflammatory status in lung tissue. Our results indicate a need for human studies that evaluate the lung responses to aerobic exercise

ACUTE EFFECT OF CIRCUIT AEROBIC AND TRADITIONAL AEROBIC TRAINING ON HAMSTRING FLEXIBILITY IN SEDENTARY WOMEN

The aim of this study is investigation of acute effect of circuit aerobic exercise and traditional aerobic exercise on hamstring muscle flexibility in sedentary women. Forty four sedentary women voluntarily participated in this study as subject. Subjects divided two groups as circuit aerobic training group (n=24), and traditional aerobic training group (n=20). For hamstring flexibility, modified sit and reach test was used. The test was applied three times as: before warm-up (T1), after immediately warm-up (T2), and after immediately exercise (T3). For warm-up intervention, 15 min mild running and static stretching were performed. Traditional aerobic exercise intervention consisted of 30 min moderate interval treadmill running. Circuit aerobic exercise intervention consisted of 30 min, 3x4 station (bench-step, jumping rope, cycling, treadmill running), and all station maintained to 3 min load with 2 min rest. Both training intervention performed at 65-75% HRmax that controlled with chest band. For statistical analysis, 2x3 mixed factor ANOVA and Bonferroni correction were used. Hamstring flexibility determined in the traditional aerobic exercise group as T1 by 13.90±4.22 cm, T2 by 19.90±4.55 cm, T3 by 29.45±6.54 cm; in the circuit aerobic exercise group as T1 by 21.20±6.89 cm, T2 by 24.08±6.67 cm, T3 by 25.62±6.67 cm. Differences between the three measurements of both groups were found statistically significant (p < 0.05). There were significant differences between T3 and T1-T2; and between T2 and T1 in both groups (p < 0.05). Differences in traditional aerobic exercise group were found more significant than circuit aerobic exercise group (p < 0.05). In summary, it could be said that hamstring flexibility increased after aerobic exercise, and at this point, traditional aerobic exercise has one step ahead of circuit aerobic exercise.  Article visualizations

Effect of progressive muscle relaxation and aerobic exercise on anxiety, sleep quality, and fatigue in patients with chronic renal failure undergoing hemodialysis

Insomnia, anxiety, and fatigue are more common in hemodialysis patients than in healthy people and affect patients' quality of life. In the present study, the effects of progressive muscle relaxation (PMR) and aerobic exercise on anxiety, sleep quality, and fatigue in patients with chronic renal failure undergoing hemodialysis were evaluated. In this double-blind clinical trial, 100 hemodialysis patients were randomly assigned to three groups: PMR, aerobic exercise, and control. Patients performed relaxation and aerobic exercise daily for 60 days. Questionnaires of anxiety, sleep quality, and fatigue were completed by participants before and after the interventions. Data were analyzed by Stata software. PMR program significantly decreased general anxiety, trait anxiety, state anxiety, and Beck anxiety and aerobic exercise significantly reduced beck anxiety. PMR program and aerobic exercise both significantly improved sleep quality in hemodialysis patients. PMR program significantly reduced Rhoten fatigue but did not affect Piper fatigue. Aerobic exercise had no effect on Rhoten and Piper fatigue. Results showed better function of PMR compared to aerobic exercise in improving the symptoms of anxiety, sleep disorders, and fatigue in hemodialysis patients. Given that fatigue and sleep quality cause severe anxiety and somehow undermine quality of life in hemodialysis patients, taking into account non-pharmacological treatments such as aerobic exercise particularly PMR is a highly economical but efficient and efficacious strategy to manage several problems of these patients. Healthcare teams can incorporate these safe programs in care designs

Design of the ExCersion-VCI study: The effect of aerobic exercise on cerebral perfusion in patients with vascular cognitive impairment

There is evidence for a beneficial effect of aerobic exercise on cognition, but underlying mechanisms are unclear. In this study, we test the hypothesis that aerobic exercise increases cerebral blood flow (CBF) in patients with vascular cognitive impairment (VCI). This study is a multicenter single-blind randomized controlled trial among 80 patients with VCI. Most important inclusion criteria are a diagnosis of VCI with Mini-Mental State Examination ≥22 and Clinical Dementia Rating ≤0.5. Participants are randomized into an aerobic exercise group or a control group. The aerobic exercise program aims to improve cardiorespiratory fitness and takes 14 weeks, with a frequency of three times a week. Participants are provided with a bicycle ergometer at home. The control group receives two information meetings. Primary outcome measure is change in CBF. We expect this study to provide insight into the potential mechanism by which aerobic exercise improves hemodynamic status
