Abstract
Fat-free mass (FFM) is a heterogeneous compartment comprising body cell mass (BCM), intracellular water (ICW), extracellular solids, and extracellular water (ECW). The BCM/FFM and ECW/ICW ratios vary among individuals and decrease with age. This study aimed to determine whether BCM/FFM and ECW/ICW ratios are predictors of maximal oxygen uptake (V̇̇O2peak) independently of age, sex, and objectively measured physical activity (PA). A total of 115 Japanese males and females, aged 55.3 ± 8.0 years (mean ± standard deviation), were included in the study. Anthropometry, explosive leg muscle power, and V̇̇O2peak were measured, and BCM, FFM, ICW, and ECW were estimated. Step count and PA were objectively measured using a triaxial accelerometer. Blood flow volume was assessed using ultrasonography. BCM and ICW were negatively correlated with age, whereas FFM and ECW were not significantly correlated with age. FFM, ICW/ECW, BCM/FFM, step counts, moderate and vigorous PA, and leg muscle power were positively correlated with V̇̇O2peak, even after adjusting for age and sex (p < .05). Multiple regression analysis indicated that either BCM/FFM or ECW/ICW, leg power, and objectively measured PA were associated with V̇̇O2peak independent of age, sex, and FFM. Blood flow volume was significantly correlated with ECW (p < .05), but not with BCM. The BCM/FFM and ECW/ICW ratios were significant predictors of V̇̇O2peak, independent of age, sex, FFM, leg power, and objectively measured PA.

Abstract
BACKGROUND Post-menopausal women have impaired cardiorespiratory responses to exercise compared to young women. Exercise training may counterbalance impairments, but the time-dependent effects of exercise training remain unclear. The current study aims to investigate the effects of rowing training on maximal aerobic capacity and time-course cardiorespiratory adaptations in older women. METHODS Female participants (n = 23) were randomly allocated to the experimental group (EXP; n = 23; 66 ± 5 years old) enrolled in rowing exercise training and control group (CON; n = 10; 64 ± 4 years old). The cardiopulmonary exercise test (CET) was performed in a cycle ergometer pre- and post-interventions. Oxygen uptake (VO2), stroke volume (SV), cardiac output (CO), and HR were recorded during CET and analyzed at the peak of the exercise. HR was monitored during exercise recovery, and the index of HRR was calculated by ΔHRR (HRpeak-HR one-minute recovery). Every two weeks, Rowing Stepwise Exercise (RSE) in a rowing machine was performed to track specific adaptations to the exercise modality. HR was continuously recorded during RSE and corrected for the average power of each step (HR/watts). The rowing training protocol consisted of three weekly sessions of 30 min at an intensity corresponding to 60-80% of peak HR for ten weeks. RESULTS Rowing exercise training increased VO2, SV, and CO at the peak of the CET, and ΔHRR. Increased workload (W) and reduced HR response to a greater achieved workload (HR/W) during RSE were observed after six weeks of training. CONCLUSIONS Rowing exercise training is a feasible method to improve cardiorespiratory performance, vagal reactivation and heart rate adjustments to exercise in older women.

Abstract
Introduction The aim of the study was to investigate the influence of training status on cardiovascular function in young male recreational and competitive rowers. Methods Ejection duration in percentage to the heart rate period (ED%), subendocardial viability ratio (SEVR), augmentation index at 75 bpm (AIx75) and carotid to femoral pulse wave velocity (cf-PWV) of competitive rowers (CR) (age 17.6 ± 4.1 years), recreational rowers (RR) (age 16.7 ± 2.70 years) and athletes practicing other recreational sports (ORS) (age 15.3 ± 1.4 years) were assessed. Results ED% was lower in CR compared to ORS (31.9 ± 3.9% vs. 38.4 ± 4.8%; p = 0.026) and cf-PWV was higher in CR compared to ORS (5.5 ± 1.0 m/s vs. 4.7 ± 0.5 m/s; p = 0.032). SEVR was higher in CR compared to RR and ORS (165.8 ± 33.7% vs. 127.4 ± 30.4% and 128.3 ± 27.8%; p = 0.022) and AIx75 was lower in CR compared to RR and ORS (-15.7 ± 8.6% vs. 1.2 ± 9.9% and 1.5 ± 9.1; p = 0.001). Discussion Healthy, young competitive male rowers reported higher myocardial performance and better cardiovascular health than recreational athletes. Interpretations of cf-PWV in competitive rowers should be performed alongside other cardiovascular indicators.

Improved arterial stiffness after combined aerobic and resistance training: correlation with heart rate variability change in prehypertensive offspring of hypertensive parents. J Exerc Rehabil 2022; 18:395-405.

Abstract
Prehypertensive offspring of hypertensive parents are strongly linked to pathological processes of hypertension in later life. It is observed that young adults with high blood pressure (BP) have increased arterial stiffness, which is linked to autonomic anomalies. The purpose of the present study was to assess the effect of combined resistance and aerobic exercise training on BP, brachial-ankle pulse wave velocity (baP-WV), and heart rate variability (HRV) in prehypertensive young men with hypertensive parents. Thirty prehypertensive males aged 19.6±1.2 years were randomly assigned to either a combined exercise training group (CBT, n=15) or no exercise group (CON, n=15). The CBT group performed combined exercise for 8 weeks, 3 times per week. BP, baP-WV, HRV, peak oxygen consumption (VO2peak), and muscle strength were measured before and after the exercise intervention. Systolic BP (-5.1 mmHg, 3.9% decrease, P<0.05), diastolic BP (-3.9 mmHg, 6.1% decrease, P<0.01), mean arterial pressure (-4.2 mmHg, 4.7% decrease, P<0.05), baPWV (-0.4 m/sec, 3.5% decrease, P<0.01), standard deviation of all RR intervals (+58.5% increase, P<0.05) and very low frequency (VLF) (+34.6% increase, P<0.01), VO2peak (+11.7% increase, P<0.01) and one-repetition maximum leg press (+30.3% increase, P<0.01) were significantly improved in the CBT group after 8 weeks of training versus the CON group. Additionally, a reduction in baPWV was associated with an increase in the VLF power of HRV (r=0.72, P<0.01). These findings indicate that the combined training improves BP, arterial stiffness, vagal activity, cardiorespiratory fitness, and lower-body muscle strength in prehypertensive offspring of hypertensive parents.

Effects of Combined Resistance and Aerobic Training on Arterial Stiffness in Postmenopausal Women: A Systematic Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18189450. [PMID: 34574374 PMCID: PMC8470196 DOI: 10.3390/ijerph18189450] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 08/27/2021] [Accepted: 09/03/2021] [Indexed: 11/24/2022]
Abstract
The aim of this systematic review was to investigate the effects of combined resistance and aerobic exercise on arterial stiffness in postmenopausal women. Two databases, PubMed and Google Scholar were searched to identify relevant studies. The methodological quality was assessed with the Physiotherapy Evidence Database (PEDro) scale. Only seven studies met the eligibility criteria, and their outcomes were presented. Four studies demonstrated the effects of combined resistance and aerobic training, while three showed the effectiveness of exercise with both training components, aerobic and resistance. In all studies, arterial stiffness was measured by brachial–ankle pulse wave velocity (baPWV). Participants were middle-aged or older postmenopausal women of various health statuses (hypertensive, with comorbidities or healthy). The results unequivocally show that combined training reduces arterial stiffness. The most important finding of this review paper is that the applied type of exercise decreased baPWV in the range of 0.6–2.1 m/s. Moreover, combined resistance and aerobic exercise for 12 weeks, performed three times a week for about 60 min per training session, at a moderate intensity (40–60% HRR or HRmax), may be clinically meaningful to the cardiovascular system. In conclusion, we can say that combined resistance and aerobic training, or exercise with resistance and aerobic components, have important health implications for the prevention of cardiovascular disease and the maintenance or improvement of health in middle-aged and older postmenopausal women with different health conditions.

Abstract
The arterial system has two primary functions. The conduit function is to transport adequate supply of oxygen and nutrients to the tissues, and the cushioning function is to buffer and cushion the pulsatile pressure exerted by intermittent ventricular contractions. The impairments in these two functions often result from physiological changes characterized by endothelial dysfunction and arterial stiffening. Habitual physical exercise has been advocated to combat these physiological dysfunctions. However, exercise is remarkably diverse, as it can be performed in different media (water, land or snow), seasons (winter or summer), and settings (individual, pair or team). In contrast to mainstream modes of exercise including walking and running, many of the alternative or "minor" forms of exercise have been under-researched by investigators in research fields and overlooked by clinicians and practitioners in clinical settings. It remains largely unknown whether these alternative forms of exercise are associated with favorable changes in arterial stiffness and endothelium-dependent vasodilation. The current review introduces and summarizes research investigations that evaluated the impacts of these under-appreciated and overlooked exercises and their impacts on key markers of vascular functions in humans.

Abstract
Regular exercise reduces the risks for cardiovascular diseases. Although the gut microbiota has been associated with fitness level and cardiometabolic risk factors, the effects of exercise-induced gut microbiota changes in elderly individuals are unclear. This study evaluated whether endurance exercise modulates the gut microbiota in elderly subjects, and whether these changes are associated with host cardiometabolic phenotypes. In a randomized crossover trial, 33 elderly Japanese men participated in a 5-week endurance exercise program. 16S rRNA gene-based metagenomic analyses revealed that the effect of endurance exercise on gut microbiota diversity was not greater than interindividual differences, whereas changes in α-diversity indices during intervention were negatively correlated with changes in systolic and diastolic blood pressure, especially during exercise. Microbial composition analyses showed that the relative abundance of Clostridium difficile significantly decreased, whereas that of Oscillospira significantly increased during exercise as compared to the control period. The changes in these taxa were correlated with the changes in several cardiometabolic risk factors. The findings indicate that short-term endurance exercise has little effect on gut microbiota in elderly individuals, and that the changes in gut microbiota were associated with cardiometabolic risk factors, such as systolic and diastolic blood pressure, providing preliminary insight into the associations between the gut microbiota and cardiometabolic phenotypes.

Abstract
Controversial data exist on acute and chronic effects of competitive sports on central hemodynamics and arterial stiffness. We investigated chronic as well as acute training effects in professional rowers. The trial was planned as a non-randomized, controlled pilot-study comparing athletes and controls. 13 German national team rowers (24.1 ± 1.5 years) and 12 controls (23.8 ± 0.8 years) participated. Aortic, brachial hemodynamics and arterial stiffness were measured (Arteriograph, TensioMed(®), Hungary) before and after a standardized exercise test. Chronic heart rate (49 [Formula: see text] 2 bpm versus 70 [Formula: see text] 2 bpm, p < 0.05) as well as brachial diastolic pressure (65 [Formula: see text] 2 mmHg versus 74 [Formula: see text] 2 mmHg, p < 0.05) was significantly lower in rowers. Physical power (305 [Formula: see text] 63 versus 158 [Formula: see text] 60 W, p < 0.001) was better. Chronic aortic pulse pressure (41.6 [Formula: see text] 6.0 versus 35.2 [Formula: see text] 3.8 mmHg; p < 0.01) and AIx (9.1 [Formula: see text] 5.4 versus 7.0 [Formula: see text] 10.2; p < 0.01) were significantly higher in athletes. After the all-out test (acute effects) pulse wave velocity (rowers: 6.6 [Formula: see text] 1.2 m s(-1) versus 7.8 [Formula: see text] 1.6 m s(-1), p < 0.001; control group 6.0 [Formula: see text] 0.4 m s(-1) versus 8.0 [Formula: see text] 1.4 m s(-1), p = 0.005) and heart rate (rowers: 49 [Formula: see text] 2 bpm versus 91 [Formula: see text] 3 bpm, p < 0.001; control group 70 [Formula: see text] 2 bpm versus 92 [Formula: see text] 4 bpm, p < 0.001) increased significantly in both groups. The controls' aortic AIx (7.0 [Formula: see text] 10.2 versus 2.0 [Formula: see text] 6.0; p < 0.01) decreased significantly after exercise. Professional rowers showed higher chronic aortic pulse pressure and arterial stiffness. Given the risk associated with elevated aortic pulse pressure and AIx for development of cardiovascular diseases, longterm observations of professional rowers are needed with respect to arterial stiffness and prognosis. Furthermore the acute effects need additional research.

Abstract
AIM This study aimed to examine whether cardiorespiratory fitness (CRF) is associated with arterial stiffening, evaluated using the cardio-ankle vascular index (CAVI), independent of visceral fat (VF) in middle-aged and elderly Japanese men. We also examined whether the relationship between CRF and the CAVI is modified by age and/or hypertension. METHODS The CAVI was determined in 157 Japanese men (age range, 30-79 years), including 96 hypertensive subjects (61.1%). CRF was assessed by measuring the peak oxygen uptake (VO2peak). The subjects were divided into low- and high-CRF groups, and the VF area was assessed using magnetic resonance imaging. RESULTS The VO2peak correlated with the CAVI following adjustment for age and body mass index in the middle-aged and elderly groups (all the subjects: r=-0.285, p<0.001; middle-aged: r=-0.240, p=0.040; elderly: r=-0.225, p=0.049). VF also correlated with the CAVI (r=0.230, p=0.004). A multiple linear regression analysis revealed that age (β=0.406, p<0.001) and the VO2peak (β=-0.186, p=0.015) were associated with the CAVI independently of VF and the mean blood pressure. Two way ANCOVA adjusted for age demonstrated that the hypertensive individuals had higher CAVI values than the normotensive individuals in the low-CRF group, whereas no significant differences in the CAVI were observed in the high-CRF group (p for interaction <0.05). CONCLUSIONS In the present study, CRF was found to be associated with the CAVI, independent of age and VF, in hypertensive middle-aged and elderly Japanese men.

Abstract
Exercise training has different effects on arterial stiffness according to training modalities. The optimal exercise modality for improvement of arterial function in normotensive and hypertensive individuals has not been well established. In this review, we aim to evaluate the effects of aerobic, resistance and combined aerobic and resistance training on arterial stiffness in individuals with and without hypertension. We systematically searched the Pubmed and Web of Science database from 1985 until December 2013 for relevant randomised controlled trials (RCTs). The data were extracted by one investigator and checked by a second investigator. The training effects on arterial stiffness were estimated using weighted mean differences of the relative changes (%) with 95% confidence intervals (CIs). We finally reviewed the results from 17 RCTs. The available evidence indicates that aerobic exercise tends to have a beneficial effect on arterial stiffness in normotensive and hypertensive patients, but does not affect arterial stiffness in patients with isolated systolic hypertension. Resistance exercise has differing effects on arterial stiffness depending on type and intensity. Vigorous resistance training is associated with an increase in arterial stiffness. There seem to be no unfavourable effects on arterial stiffness if the training is of low intensity, in a slow eccentric manner or with lower limb in healthy individuals. Combined training has neutral or even a beneficial effect on arterial stiffness. In conclusion, our review shows that exercise training has varying effects on arterial stiffness depending on the exercise modalities.

Abstract
AIMS OF THE STUDY Stiffening of large arteries has been associated with increased cardiovascular outcomes among older subjects. Endurance exercises might attenuate artery stiffness, but little is known about the effects of intermittent training programme. We evaluate the effect of a short Intermittent Work Exercise Training Program (IWEP) on arterial stiffness estimated by the measure of the pulse wave velocity (PWV). METHODS AND SUBJECTS Seventy-one healthy volunteers (mean age: 64.6 years) free of symptomatic cardiac and pulmonary disease performed a 9-week IWEP that consisted of a 30-min cycling twice a week over a 9-week period. Each session involved six 5-min bouts of exercise, each of the latter separated into 4-min cycling at the first ventilatory threshold alternated with 1-min cycling at 90% of the pretraining maximal tolerated power. Before and after the IWEP, the following measurements were made: carotid-radial PWV and carotid-femoral PWV with a tonometer and systolic and diastolic blood pressure. RESULTS Training resulted in a non-significant decrease of the carotid-radial PWV, a significant decrease of the carotid-femoral PWV from 10.2 to 9.6 m/s (p < 0.001) (that was no longer significant after adjustment for mean arterial pressure) and a significant decrease in both systolic and diastolic blood pressure, respectively, from 129.6 ± 14.9 mmHg to 120.1 ± 14.1 mmHg (p < 0.001) and from 77.2 ± 8.8 mmHg to 71.4 ± 10.1 mmHg (p < 0.001). CONCLUSION The present results support the idea that a short-term intermittent aerobic exercise programme may be an effective lifestyle intervention for reducing rapidly blood pressure and probably central arterial stiffness among older healthy subjects.

Abstract
Arterial stiffness has been identified as an independent predictor of prognostic outcomes for patients with cardiovascular disease. Although measurement of pulse wave velocity has been a widely accepted noninvasive approach to the assessment of arterial stiffness, its accuracy is hampered by changes in blood pressure. Taking the exponential relation between intravascular pressure and arterial diameter into consideration, a stiffness parameter can be obtained by plotting the natural logarithm of systolic–diastolic pressure ratio against the arterial wall extensibility. Cardio-ankle vascular index (CAVI), which is calculated based on the stiffness parameter thus obtained, is theoretically independent of changes in blood pressure. With this distinct advantage, CAVI has been widely applied clinically to assess arterial stiffness in subjects with known cardiovascular diseases including those with diagnosed atherosclerosis, coronary heart disease, and stroke as well as those at risk, including those with hypertension, diabetes, the elderly, and the obese. Because of its enhanced sensitivity, not only has the index been used to discern subtle changes in the disease process, it has also been utilized in studying normal individuals to assess their potential risks of developing cardiovascular diseases. The primary aims of assessing arterial stiffness using CAVI are not only to aid in early detection of arteriosclerosis to allow timely treatment and change in lifestyle, but also to quantitatively evaluate the progression of disease and the effectiveness of treatment. Despite its merit of being unaffected by blood pressure, discretion in data interpretation is suggested because an elevated CAVI represents not just vascular stiffness caused by pathological changes in the arterial wall, but can also be attributed to an increased vascular tone brought about by smooth muscle contraction. Moreover, certain patient populations, such as those with an ankle-brachial index < 0.9, may give falsely low CAVI and are suggested to be excluded from study.
