And Training

It is established that regular aerobic training improves vascular function, for example, endothelium-dependent vasodilatation and arterial stiffness or compliance and thereby constitutes a preventative measure against cardiovascular disease. In contrast, high-intensity resistance training impairs vascular function, while the influence of moderate-intensity resistance training on vascular function is still controversial. However, aerobic training is insufficient to inhibit loss in muscular strength with advancing age; thus, resistance training is recommended to prevent sarcopenia. Recently, several lines of study have provided compelling data showing that exercise and training with blood flow restriction (BFR) leads to muscle hypertrophy and strength increase. As such, BFR training might be a novel means of overcoming the contradiction between aerobic and high-intensity resistance training. Although it is not enough evidence to obtain consensus about impact of BFR training on vascular function, available evidences suggested that BFR training did not change coagulation factors and arterial compliance though with inconsistence results in endothelial function. This paper is a review of the literature on the impact of BFR exercise and training on vascular function, such as endothelial function, arterial compliance, or other potential factors in comparison with those of aerobic and resistance training.

Training Programmes

Regular exercise training is recognized as a powerful tool to improve work capacity, endothelial function and the cardiovascular risk profile in obesity, but it is unknown which of high-intensity aerobic exercise, moderate-intensity aerobic exercise or strength training is the optimal mode of exercise. In the present study, a total of 40 subjects were randomized to high-intensity interval aerobic training, continuous moderate-intensity aerobic training or maximal strength training programmes for 12 weeks, three times/week. The high-intensity group performed aerobic interval walking/running at 85–95% of maximal heart rate, whereas the moderate-intensity group exercised continuously at 60–70% of maximal heart rate; protocols were isocaloric. The strength training group performed ‘high-intensity’ leg press, abdominal and back strength training. Maximal oxygen uptake and endothelial function improved in all groups; the greatest improvement was observed after high-intensity training, and an equal improvement was observed after moderate-intensity aerobic training and strength training. High-intensity aerobic training and strength training were associated with increased PGC-1α (peroxisome-proliferator-activated receptor γ co-activator 1α) levels and improved Ca2+ transport in the skeletal muscle, whereas only strength training improved antioxidant status. Both strength training and moderate-intensity aerobic training decreased oxidized LDL (low-density lipoprotein) levels. Only aerobic training decreased body weight and diastolic blood pressure. In conclusion, high-intensity aerobic interval training was better than moderate-intensity aerobic training in improving aerobic work capacity and endothelial function. An important contribution towards improved aerobic work capacity, endothelial function and cardiovascular health originates from strength training, which may serve as a substitute when whole-body aerobic exercise is contra-indicated or difficult to perform.

AbstractIn this meta-analysis, the aims were to examine the effects of resistance training with and without blood flow restriction on vascular function. Five databases were searched up to June 2020 for papers about resistance training with blood flow restriction influence on vascular function. The quality of each identified study was evaluated. Effect sizes were estimated in terms of the standardized mean difference. A subgroup analysis was conducted according to participants’ age, training duration, and cuff pressure. The results of six studies on arterial compliance and five on vascular function were highly homogenous regarding responses to resistance training with or without blood flow restriction. Resistance training with blood flow restriction had a more positive effect for regulating arterial compliance than resistance training without blood flow restriction, but not for vascular function. Resistance training with blood flow restriction leads to a more positive effect on vascular function than resistance training when training for no longer than four weeks.

Abstract Introduction: Sarcoidosis-related fatigue and skeletal muscle dysfunction are frequent symptoms in patients with sarcoidosis. Despite lacking knowledge whether high-intensity resistance training (RT) will worsen fatigue, low to moderate intensity is commonly recommended. This study aimed to investigate whether a single session of high-intensity RT will induce a larger acute increase in fatigue than a single RT session of moderate-intensity. Methods: In this crossover study, 41 patients with pulmonary sarcoidosis (age: 53 ± 11 yr) were recruited. They randomly performed one session of high-intensity, 4 sets x 5 repetitions maximum (5RM), and one session of moderate-intensity, 2 sets x 25 RM. Fatigue was assessed with the Visual Analogue Scale (0-100 mm) before (T0), immediately after (T1) and 24 hours after (T2) each exercise session. Results: Fatigue development from T0 to T1 was significantly lower after 5RM (– 3 ± 18 mm) than after 25RM (5 ± 15 mm), p = 0.004. No difference was seen from T0 to T2 between 5RM (0 ± 17 mm) and 25RM (6 ± 18 mm), p = 0.147. Conclusion: Since the 5RM session did not induce a larger increase in fatigue than the 25RM session, a single session of RT thus appears feasible and safe in patients with pulmonary sarcoidosis irrespective of the RT intensity. The long-term effects of high-intensity RT on fatigue should be explored in a RT program of longer duration.

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.

This study evaluated the hypothesis that active muscle blood flow is lower during exercise at a given submaximal power output after aerobic conditioning as a result of unchanged cardiac output and blunted splanchnic vasoconstriction. Eight untrained subjects (4 men, 4 women, 23–31 yr) performed high-intensity aerobic training for 9–12 wk. Leg blood flow (femoral vein thermodilution), splanchnic blood flow (indocyanine green clearance), cardiac output (acetylene rebreathing), whole body O2 uptake (V˙o 2), and arterial-venous blood gases were measured before and after training at identical submaximal power outputs (70 and 140 W; upright 2-leg cycling). Training increased ( P < 0.05) peak V˙o 2(12–36%) but did not significantly change submaximalV˙o 2 or cardiac output. Leg blood flow during both submaximal power outputs averaged 18% lower after training ( P = 0.001; n = 7), but these reductions were not correlated with changes in splanchnic vasoconstriction. Submaximal leg V˙o 2 was also lower after training. These findings support the hypothesis that aerobic training reduces active muscle blood flow at a given submaximal power output. However, changes in leg and splanchnic blood flow resulting from high-intensity training may not be causally linked.
