“…The present data further show that both training programmes induced reductions in HR at the same absolute work loads during the maximal graded exercise test, that is, at the loads of 40, 80 and 120 W. Moreover, in agreement with others, 34,35 we found aerobic conditioning to be more pronounced after HI compared with LI training, that is, HI induced a more pronounced reduction in HR and a more pronounced increase in VO 2peak during the exercise test compared with LI training. The current results show an elevated HR during the first 45 min of recovery compared with pre-exercise rest values, which is consistent with previous data, [36][37][38] but in contrast to Perini et al 18 With regard to the spectral components of HRV, we observed that the relative LF component in the recovery period was not different from pre-exercise rest values, [37][38][39] whereas the HF component during the recovery period was slightly lower than control.…”

Effects of aerobic training intensity on resting, exercise and post-exercise blood pressure, heart rate and heart-rate variability

We aimed to investigate the effects of endurance training intensity (1) on systolic blood pressure (SBP) and heart rate (HR) at rest before exercise, and during and after a maximal exercise test; and (2) on measures of HR variability at rest before exercise and during recovery from the exercise test, in at least 55-year-old healthy sedentary men and women. A randomized crossover study comprising three 10-week periods was performed. In the first and third period, participants exercised at lower or higher intensity (33% or 66% of HR reserve) in random order, with a sedentary period in between. Training programmes were identical except for intensity, and were performed under supervision thrice for 1 h per week. The results show that in the three conditions, that is, at rest before exercise, during exercise and during recovery, we found endurance training at lower and higher intensity to reduce SBP significantly (Po0.05) and to a similar extent. Further, SBP during recovery was, on average, not lower than at rest before exercise, and chronic endurance training did not affect the response of SBP after an acute bout of exercise. The effect of training on HR at rest, during exercise and recovery was more pronounced (Po0.05) with higher intensity. Finally, endurance training had no significant effect on sympathovagal balance. In conclusion, in participants at higher age, both training programmes exert similar effects on SBP at rest, during exercise and during post-exercise recovery, whereas the effects on HR are more pronounced after higher intensity training.

“…The results of the study conducted by Church et al indicated that one of the most important factors affecting adherence to the treatment plan is to train the patients in relation to their conditions (18). In the present study, there was a significant difference between the mean scores of the patients' adherence to the entire treatment plan in the experimental group before and after intervention in a way that the patients' adherence to the entire treatment plan increased.…”

Background: Coronary artery diseases are among the most important causes of disability and coronary artery bypass graft (CABG) surgery is considered as one of the most important methods of treatment. The improvement of post-surgery adherence to treatment plan is one of the main healthcare objectives. Objectives: The present study attempted to determine the effect of family-centered empowerment model on the adherence of patients undergoing CABG to the treatment plans. Methods: This research was a clinical trial and a quasi-experimental study, including pre and post tests with a control group performed on 102 patients and active family members of the patients hospitalized at the intensive care unit (ICU) of Imam Khomeini hospital of Tehran, Iran in 2014. For the experimental group, the family-centered empowerment model was implemented with four steps. The control group received only common care. The rate of patients' adherence to the treatment plans was then investigated in three areas of diet, medication, and physical activities before and after the intervention, and the data were analyzed using PASW Statistics V18 software. Results: The two groups were similar in terms of demographic variables. After the intervention, there was a significant difference based on the results of the independent T-test in terms of mean scores of adherence to the treatment plan in the three areas mentioned above (P = 0.000). Also, before and after the intervention, a significant difference was observed in the experimental group in terms of the above mean scores (P = 0.000). Conclusions: Based on the research findings, the family-centered empowerment model seems to be practical and feasible for the patients under CABG, which can bring improvement or correction of adherence to the treatment plan.

“…Participant factors such as stress, anxiety and time since the last exercise session may have affected the test results. Cardio-respiratory fitness levels in the Aerobic group may eventually have increased significantly given a longer training period, such as that by Church et al, [36] which employed a six month intervention. However, our Combination intervention demonstrates that improvements in cardiorespiratory fitness in the overweight and obese can be achieved following the Australian physical activity recommendations.…”

Background: Evidence suggests that exercise training improves CVD risk factors. However, it is unclear whether health benefits are limited to aerobic training or if other exercise modalities such as resistance training or a combination are as effective or more effective in the overweight and obese. The aim of this study is to investigate whether 12 weeks of moderate-intensity aerobic, resistance, or combined exercise training would induce and sustain improvements in cardiovascular risk profile, weight and fat loss in overweight and obese adults compared to no exercise.
