ABSTRACT Introduction: The main purpose of aerobic exercise is to enhance cardiopulmonary endurance, so it is necessary to build cardiopulmonary endurance response models based on different frequencies of aerobic exercise. Objective: To study the cardiopulmonary endurance response of women to different frequencies of aerobic exercise. Methods: Twenty young female desk workers (female teachers and civil servants) who worked out at a fitness club were randomly divided into two groups. Cardiopulmonary function, both before and after 16 weeks of aerobic exercise at different exercise loads, was studied and analyzed. Results: After 16 weeks of aerobic exercise at different exercise loads, all the young women had significantly improved their vital capacity (VC), and their maximum oxygen uptake ability was improved to a certain extent. Compared with the 45-minute aerobic exercise group, the vital capacity (VC)of 90-minute aerobic exercise group was significantly increased (P>0.05). Conclusions: When performed at a consistent frequency level, aerobic exercise with a relatively high exercise load can better develop the body’s respiratory system function. This may be due to deep stimulation of the respiratory system from high-load aerobic exercise, and ultimately to the intensive exercising of lung function.

Purpose This paper aims to verify the effect of 12 weeks of grape juice (GJ) consumption associated with aerobic exercise on the variation of the hypertensive elderly pressure. Design/methodology/approach A total of 45 hypertensive elderly of both sexes were distributed into: control group (CG, n = 10), exercise group (EG, n = 10), juice group (JG, n = 12) and juice and exercise group (JEG, n = 13). Blood pressure and heart rate were checked weekly before exercise in JG and JEG, and before and after intervention in all groups, with JG and JEG supplemented with 200 mL of GJ. Three weekly sessions of moderate walking were applied. Findings There was a reduction in EG, JG and JEG for systolic pressure and diastolic only for JG and JEG. The GJ consumption to the practice of aerobic exercise provided reductions in the arterial pressure of hypertensive, in addition to stabilization of the diastolic pressure. Research limitations/implications Although the objective of the study was to compare the effect and value of intervention with controls, the study had no intervention in food consumption, which could have led to more significant results. There was a limitation in the control drink, leading the study not to be blind, which may have impaired the results. However, it is probably not a bias, as the groups were divided by residence area, and therefore, had no direct contact with the other groups. Another limitation was that the sample size was still small, which would lead to more reliable results. Finally, although the existing limitations cannot be disregarded, the results of this research are very promising, especially when the objective is the effect of GJ and aerobic exercise on blood pressure, with the possibility of implementing supplemental GJ and the inclusion or not of exercise to the hypertensive elderly. Originality/value The paper deals with the benefits of GJ consumption associated with aerobic physical exercise on the blood pressure of elderly hypertensive patients. Considering that GJ along with physical exercise was enough to reduce the blood pressure of hypertensive elderly, this may be a new model to be used to reduce and/or control blood pressure, and GJ and the exercise to be part of the daily life of the population.

Objective: This study attempted to determine whether the effects of physical exercise were reflected in the resting electroencephalographic (EEG) pattern of ADHD children. Method: Thirty-two ADHD children were assigned to either an exercise group or a control group. The exercise group participated in a water aerobics program for 8 weeks, whereas no intervention was administered to the control group. Resting EEGs were recorded under open-eyes condition before and after the intervention. Data from eligible participants, 15 from the exercise group (11 boys and 4 girls, 7.93 ± 1.02 years) and 14 from the control group (14 boys, 8.27 ± 1.04 years), were further analyzed. Results: While controlling for the baseline resting EEG, separate ANCOVAs indicated that the exercise group showed smaller theta/alpha ratios over the frontal and central brain sites after the intervention compared with the control group. Conclusion: This finding suggests that aerobic exercise may enhance the cognitive functions of children with ADHD, as reflected in resting EEG.

AbstractPurpose. The purpose of this study was to evaluate the effect of regular swimming activity on the respiratory system of smokers and non-smokers. Methods. The study included 196 students, aged 19 to 24 years, attending weekly swimming classes. All students underwent pulmonary function testing before and after participating in a swimming program for 10 months. Measurements included forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and peak expiratory flow (PEF). Maximal inspiratory and expiratory pressure at the mouth (PImax, PEmax) and the percentage carboxyhemoglobin level in blood (%CoHb) were also measured. Results. After 10 months of regular swimming activity the values of FVC, PEF, MIP and MEP increased in the non-smoking as well as in the smoking group, while the FEV1 increased only among smokers. The percentage of CoHB level in the blood decreased in both groups. Conclusions. The study confirmed the positive effect of swimming on respiratory system function and the importance of promoting physical activity such as swimming among cigarette smokers as well as non-smokers.

ABSTRACT Introduction Individuals with schizophrenia tend to have high levels of cortisol and changes in the serotonergic mechanism. However, the effects of aerobic exercises on cortisol and serotonin levels in schizophrenic inpatients are not well established. Objective To evaluate the effects of an aerobic training program on serotonin and cortisol levels in schizophrenic inpatients. Methods Thirty schizophrenic subjects were randomly assigned to an exercise group (EG; n = 15; age: 29 ± 9.08 years; BMI: 23.57 ± 4.33 kg/m2) or a control group (CG; n = 15; age: 33.17 ± 12.8 years; BMI: 22.89 ± 5.68 kg/m2). EG performed an aerobic training program in a cycle ergometer (57% to 67% of the maximum heart rate) for 30 minutes, five days a week, with a total of twenty sessions. The analysis of cortisol (Chemiluminescence Method) and serotonin (High Performance Liquid Chromatography) was performed before and after testing in both groups. The level of significance was of p<0.05. Results After the exercise sessions, EG showed a significant reduction in cortisol levels (Δ = -5.68 mcg/dl%, p < 0.0001) and a significant increase in serotonin levels (Δ = 47.63 ng/ml, p = 0.015) compared to CG. Conclusion The aerobic training program was effective in reducing cortisol levels and increasing serotonin levels in schizophrenic inpatients. Level of evidence I; Randomized clinical trial.

ABSTRACT Introduction Patients with cerebrovascular accident and hemiplegia need to perform physical exercise and aerobic training, but physical dysfunction restricts the performance of these activities. Objective The article aims to develop physical strength sports for stroke patients with hemiplegia to explore the efficacy of sports to regain limb function in these patients. Methods We randomly selected 30 patients with stroke sequelae and divided them into control and exercise groups. While undergoing rehab, the exercise group performed a certain amount of aerobic exercise. During this period, we compared the relevant physiological indicators of the patients, and, at the same time, we used the Fugle-Meyer motor function scoring method to assess limb function. Results The two groups of patients are significantly different regarding the recovery of physical function and the capacity for daily life. Physiological indicators of patients are also different. Conclusion Low-intensity aerobic exercise can help stroke and hemiplegia patients regain their basic ability to live and exercise.

Cardiorespiratory fitness (CRF) is assumed to exert beneficial effects on brain structure and executive control (EC) performance. However, empirical evidence of exercise-induced cognitive enhancement is not conclusive, and the role of CRF in younger adults is not fully understood. Here, we conducted a study in which healthy young adults took part in a moderate aerobic exercise intervention program for 9 weeks (exercise group; n = 48), or control condition of non-aerobic exercise intervention (waitlist control group; n = 72). Before and after the intervention period maximal oxygen uptake (VO2max) as an indicator of CRF, the Flanker task as a measure of EC performance and grey matter volume (GMV), as well as cortical thickness via structural magnetic resonance imaging (MRI), were assessed. Compared to the control group, the CRF (heart rate, p < 0.001; VO2max, p < 0.001) and EC performance (congruent and incongruent reaction time, p = 0.011, p < 0.001) of the exercise group were significantly improved after the 9-week aerobic exercise intervention. Furthermore, GMV changes in the left medial frontal gyrus increased in the exercise group, whereas they were significantly reduced in the control group. Likewise, analysis of cortical morphology revealed that the left lateral occipital cortex (LOC.L) and the left precuneus (PCUN.L) thickness were considerably increased in the exercise group, which was not observed in the control group. The exploration analysis confirmed that CRF improvements are linked to EC improvement and frontal grey matter changes. In summary, our results support the idea that regular endurance exercises are an important determinant for brain health and cognitive performance even in a cohort of younger adults.

ABSTRACTAn intervention trial with regular physical activity was carried out to test the hypothesis that walking speed is related to the level of cardiovascular fitness (maximal oxygen uptake). Earlier research has demonstrated that when VO2 max is held constant in a multiple regression analysis the association between walking speed and age (29–65 y) is eliminated. To describe the association between self-selected speeds of walking, and level of cardiovascular fitness, 63 men age 60 to 65 were studied before and after a 1 year program of exercise training. VO2 max was determined on a motor driven treadmill. A test of self-selected walking pace was administered over a 240 m indoor course. The men were asked to walk at 3 paces considered by the subjects to be rather slow, normal, and fast, respectively. They were randomly assigned with stratification for white and blue collar occupation to a program of exercise training (n = 33) or control (n = 27). The training program consisted of walking or jogging for 30 min three times per week for one year. After the training program the exercise group increased their VO2 max (9.5%) and their normal walking speed (1.29 to 1.43 m.s−1) significantly compared to the controls. A program of exercise endurance training will result in an increase in the speed of self-selected pace.

Objective. To examine the effect of acute and short-term (~1 week) aerobic exercise training on plasma adiponectin levels in inactive, abdominally obese men.Materials and Methods. Inactive and abdominally obese men (n=38, waist circumference ≥102 cm) recruited from Kingston, Canada were randomly allocated to perform three bouts of aerobic treadmill exercise at either low (50% VO2peak) or high (75% VO2peak) intensity during a 1-week period. Blood samples were taken before and after the first exercise session and 24–72 hours following the completion of the final exercise session.Results. Adiponectin levels were elevated immediately following an acute bout of exercise at both high and low intensities (High:5.79±0.42versus5.05±0.41 ug/mL; Low:5.24±0.44versus4.37±0.44 ug/mL,P<0.05) and remained elevated following 30 minutes of rest. In comparison to baseline, adiponectin levels were also elevated 24–72 hours following the final exercise session (High:5.47±0.48versus4.88±0.48 ug/mL; Low:5.18±0.49versus4.47±0.49 ug/mL,P<0.05).Conclusion. Both acute and short-term aerobic exercise result in a significant increase in plasma adiponectin levels in inactive, abdominally obese men independent of intensity.

Objectives: Myocardial infarction (MI)-induced heart failure (HF) is commonly accompanied with profound effects on skeletal muscle. With the process of MI-induced HF, perturbations in skeletal muscle contribute to muscle atrophy. Exercise is viewed as a feasible strategy to prevent muscle atrophy. The aims of this study were to investigate whether exercise could alleviate MI-induced skeletal muscle atrophy via insulin-like growth factor 1 (IGF-1) pathway in mice. Materials and Methods: Male C57/BL6 mice were used to establish the MI model and divided into three groups: sedentary MI group, MI with aerobic exercise group and MI with resistance exercise group, sham-operated group was used as control. Exercise-trained animals were subjected to four-weeks of aerobic exercise (AE) or resistance exercise (RE). Cardiac function, muscle weight, myofiber size, levels of IGF-1 signaling and proteins related to myogenesis, protein synthesis and degradation and cell apoptosis in gastrocnemius muscle were detected. And H2O2-treated C2C12 cells were intervened with recombinant human IGF-1, IGF-1R inhibitor NVP-AEW541 and PI3K inhibitor LY294002 to explore the mechanism. Results：Exercises up-regulated the IGF-1/IGF-1R-phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling, increased the expressions of Pax7, myogenic regulatory factors (MRFs) and protein synthesis, reduced protein degradation and cell apoptosis in MI-mice. In vitro, IGF-1 up-regulated the levels of Pax7 and MRFs, mTOR and P70S6K, reduced MuRF1, MAFbx and inhibited cell apoptosis via IGF-1R-PI3K/Akt pathway. Conclusion: AE and RE, safely and effectively, alleviate skeletal muscle atrophy by regulating the levels of myogenesis, protein degradation and cells apoptosis in mice with MI via activating IGF-1/IGF-1R-PI3K/Akt pathway.
