Muscle Training

Arterial hypertension is associated to sympathetic hyperactivity and endothelial dysfunction. Aerobic training (AT) is highly recommended to improve vascular function minimizing complications and Inspiratory muscle training (IMT) has demonstrated beneficial effects in this population, especially improving cardiovascular autonomic control. We sought to observe the effects of both training modalities on baroreflex sensitivity, sympathetic activity and endothelial function, in patients with controlled arterial hypertension. 10 patients (55±4 years old, both genders) were included and allocated into two groups: IMT (n=5, 7days/week, 30min/day, load=30%PImax) and AT (n=5, 2days/week, 1hour/day, load=70%HRmax). Both training protocols were performed during 12 weeks. Blood pressure (BP) and heart rate (HR) signals were recorded before and after protocols, as well as the other evaluations, by pulse telemetry (Finometer®PRO) and ECG (PowerLab®). Arterial baroreflex sensitivity was analysed by sequence method. Sympathetic activity was evaluated by microneurography (PowerLab®) and the endothelial function was evaluated by flow mediated dilation (EnVisor CHD, Philips, Bothell, WA, USA). After 12 weeks treatment IMT improved baroreflex sensitvity to both tachycardic and bradycardic responses respectively (BRR Down Gain (mean): IMT=26.51(±1.7)vs15.57(±6.7), AT=13.94(±5.5)vs17.92(±1.6); BRR Up Gain (mean): IMT=17.16(±1.2)vs16.28(±1.1), AT=12.39(±5)vs12.69(±3.3)). Additionally, we observed reduction of sympathetic activity in both groups (IMT:33.23±11.79vs25.07±13.28; AT:29.88±7.07vs24.09±6.37) and improvement of endothelial function independent of the treatment (IMT:6.4±2.18vs7.22±2.08; AT:5.49±7.43vs7.06±3.12). Regarding the responses to inspiratory muscle training and aerobic training on autonomic cardiovascular control and endothelial function in Hypertension, we demonstrated for the first time that IMT and AT present quite similar effects in patients with controlled blood pressure.

Heart Failure Patients

Evidence from large multicentre exercise intervention trials in heart failure patients, investigating both moderate continuous aerobic training and high intensity interval training, indicates that the ‘crème de la crème’ exercise programme for this population remains to be found. The ‘aerobic/resistance/inspiratory (ARIS) muscle training hypothesis in heart failure’ is introduced, suggesting that combined ARIS muscle training may result in maximal exercise pathophysiological and functional benefits in heart failure patients. The hypothesis is based on the decoding of the ‘skeletal muscle hypothesis in heart failure’ and on revision of experimental evidence to date showing that exercise and functional intolerance in heart failure patients are associated not only with reduced muscle endurance, indication for aerobic training (AT), but also with reduced muscle strength and decreased inspiratory muscle function contributing to weakness, dyspnoea, fatigue and low aerobic capacity, forming the grounds for the addition of both resistance training (RT) and inspiratory muscle training (IMT) to AT. The hypothesis will be tested by comparing all potential exercise combinations, ARIS, AT/RT, AT/IMT, AT, evaluating both functional and cardiac indices in a large sample of heart failure patients of New York Heart Association class II–III and left ventricular ejection fraction ≤35% ad hoc by the multicentre randomized clinical trial, Aerobic Resistance, InSpiratory Training OutcomeS in Heart Failure (ARISTOS-HF trial).

6 Minute Walk Test

The effect of hypothyroidism on the respiratory system is proven in various studies. The study is aimed to compare Inspiratory muscle training and Aerobic training on lung functions, exercise capacity & cardiorespiratory fitness in females having hypothyroidism. This comparative study was executed on 66 subjects based on the criteria of the study, which were randomly divided into Group A & B. Subjects in Group A received Inspiratory Muscle Training. Still, subjects in Group B received Aerobic Training for four weeks. Spirometry assessed pulmonary functions, exercise capacity was evaluated by the 6-Minute Walk Test, and cardiorespiratory fitness was assessed by Step Harvard test. All measurements were taken at the baseline, on the last day of 2nd week and final day of 4th week. Independent t-test and Analysis of Variance (ANOVA) were used to analyze the data. More significant improvement in terms of pulmonary functions, exercise capacity and Cardiorespiratory fitness was observed, in group B who received Aerobic training in contrast to group A that received Inspiratory muscle training. Results of this study showed Aerobic training to be more effective and beneficial in improving pulmonary functions, exercise capacity and cardiorespiratory fitness than Inspiratory Muscle Training.

Preoperative Exercise

Preoperative physical exercise protocols prior to cancer surgery increased in popularity over recent years; however, the beneficial effect of such protocols is not well established, with conflicting results reported. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to assess the effects of different modalities or combinations of preoperative exercise interventions and/or prehabilitation multicomponent training in patients with non-small-cell lung cancer (NSCLC) after surgery on the outcomes related to functional capacity, mental wellness and medical care. We searched in OVID Embase, Pubmed, Cochrane Library, CINAHL, Scopus, and Web of Science. Characteristics of studies and program results and outcome data were extracted. Changes between the intervention and control groups, from baseline to follow-up (standardized mean difference (SMD) or relative risk (RR) with 95% confidence interval (CI) for each intervention was pooled using weighted random-effects models). A total of 676 participants from 10 RCTs were included in the final analysis (aerobic training + inspiratory muscle training, n = 5; aerobic training + strength training + inspiratory muscle training, n = 2; aerobic training + strength training, n = 1; multicomponent training, n = 1; aerobic training alone, n = 1). The results showed intervention-induced improvement in walking endurance (SMD = 0.27; 95% CI, 0.11 to 0.44; I2 = 0.0%), peak exercise capacity (SMD = 0.78; 95% CI, 0.35 to 1.21; I2 = 76.7%), dyspnoea (SMD = −0.30; 95% CI, −0.51 to −0.10; I2 = 0.0%), risk of hospitalization (SMD = −0.58; 95% CI, −0.97 to −0.20; I2 = 70.7%), and postoperative pulmonary complications (relative risk (RR) = 0.50; 95% CI, 0.39 to 0.66; I2 = 0.0%). For the functional capacity and medical care parameters, preoperative combined aerobic, resistance, and inspiratory muscle training was shown to be effective if comprising one to four weeks, performing 1–3 sessions per week, with moderate intensity (50% for endurance capacity). Further studies with larger samples and higher methodological quality are needed to clarify the potential benefits of preoperative exercise training for patients with NSCLC.
