Beneficial Effects

Background<br />Exercise has been known to have beneficial effects on human health. The kidneys play an important role in regulating acid-base and water-electrolyte balance disturbances induced by exercise. The objective of this study was to investigate the effect of short term aerobic exercise (volleyball training) on the kidney function of apparently healthy individuals. <br /><br />Methods<br />An experimental study of pre-post test design was conducted involving 41 amateur volleyball players, comprising 22 males and 19 females. They were randomly divided into seven different teams. Each team trained for at least 45 minutes for four consecutive days for two weeks. Both pre-and post-exercise blood pressure (BP) was measured using an automatic blood pressure measuring device OMRON 907 (OMRON, Hoofddorp, Netherlands). Likewise, both pre- and post-exercise blood samples were collected into lithium heparin tubes and centrifuged at 3000 rpm for 10 minutes and the plasma separated into plain tubes. Electrolytes were analysed using ion selective electrode machine (SFRI 4000, Germany), urea using modified Berthelot method, creatinine using Jaffe-Slot method and uric acid using the uricase method and estimated glomerular filtration state (eGFR) was calculated using the Modification of Diet in Renal Disease (MDRD) formula. <br /><br />Results<br />The mean levels of pre- and post-exercise systolic blood pressure, creatinine, urea, sodium, potassium, chloride, bicarbonate and eGFR did not differ significantly (p&gt;0.05). However, serum uric acid was significantly increased (p&lt;0.05), while diastolic BP significantly decreased after exercise (p&lt;0.05).<br /><br />Conclusion<br />The study showed that short-term moderate intensity aerobic exercise does not have any significant effect on the renal functions.

Pulsatile Load

Following aerobic exercise, sustained vasodilation and concomitant reductions in total peripheral resistance (TPR) result in a reduction in blood pressure that is maintained for two or more hours. However, the time course for postexercise changes in reflected wave amplitude and other indices of pulsatile load on the left ventricle have not been thoroughly described. Therefore, we tested the hypothesis that reflected wave amplitude is reduced beyond an hour after cycling at 60% V̇O2peak for 60 min. Aortic pressure waveforms were derived in 14 healthy adults (7 men, 7 women; 26 ± 3 yr) from radial pulse waves acquired via high-fidelity applanation tonometry at baseline and every 20 min for 120 min postexercise. Concurrently, left ventricle outflow velocities were acquired via Doppler echocardiography and pressure-flow analyses were performed. Aortic characteristic impedance (Zc), forward (Pf) and backward (Pb) pulse wave amplitude, reflected wave travel time (RWTT), and wasted pressure effort were derived. Reductions in aortic blood pressure, Zc, Pf, and Pb were all sustained postexercise while increases in RWTT emerged from 60-100 min post exercise (all P<0.05). WPE was reduced by ~40% from 40-100 min post exercise (all P<0.02). Stepwise multiple regression analysis revealed that the peak ∆WPE was associated with ∆RWTT (β=-0.57, P=0.003) and ∆Pb (β=0.52, P=0.006), but not ∆cardiac output, ∆TPR, ∆Zc, or ∆Pf. These results suggest that changes in pulsatile hemodynamics are sustained for ≥100 min following moderate intensity aerobic exercise. Moreover, decreased and delayed reflected pressure waves are associated with decreased left ventricular wasted effort after exercise.

Resistance Exercises

Combined exercise training (CT) including aerobic plus resistance exercises could be more effective in comparison with aerobic exercise (AT) alone in reducing blood pressure variability (BPV) in hypertensive patients. We report that CT was indeed more effective than AT in reducing short-term BPV, and both exercise modalities reduced BP levels to the same extent. CT appears to be a more appropriate exercise modality if the objective is to reduce BPV in addition to BP levels.

AbstractThis study investigated the acute post-exercise effect of high-velocity resistance exercise on ambulatory blood pressure in hypertensive older women. Fourteen volunteers (67.9±5.1 years) performed a high-velocity resistance exercise session (8 exercises using Thera-Band, 3 sets of 6 repetitions as fast as possible in the concentric phase with moderate intensity) and a control session, separated by a 7–10-day period. Ambulatory blood pressure was monitored following 12-h post-sessions and compared between conditions at 1 to 4-h, 5 to 8-h, and 9 to 12-h. Average 24-h ambulatory blood pressure, awake, asleep periods, and blood pressure load were also analyzed. There was a condition by time interaction for systolic ambulatory blood pressure over 12-h post-sessions (P=0.043). It was observed a lower systolic ambulatory blood pressure in the first 4-h period following the high-velocity resistance exercise session compared to the control session (−6.7 mmHg, 95% CI  − 11.6 to −1.8 mmHg; P=0.011). No changes were observed for diastolic ambulatory blood pressure over 12-h post-sessions as well as for the other variables analyzed (P>0.05). In summary, a single high-velocity resistance exercise session elicits a post-exercise antihypertensive effect and may be considered as a strategy to acutely improve blood pressure control in hypertensive older women.

Intense Physical Activity

Exercise is defined as any activity that causes your muscles to work and your body to burn calories. Physical activity includes swimming, running, jogging, strolling, and dancing, to name a few. Physically and mentally active people have been shown to have various health benefits. It could even help you live a longer life. In this article, we attempt to explain the beneficial effects of exercising regularly on our brain and how this helps with cognitive tasks. We also describe the various neurotrophic neurochemicals that aid in this phenomenon. We then describe the process of neuroplasticity and how exercise can help accelerate this process. Regular physical activity is one of the most important things you can do for your health. If you're worried about being harmed if you start walking or increase your level of physical activity, it is safe for most people to engage in moderate-intensity aerobic activity, such as brisk walking. Reduced emotions of state anxiety (short-term anxiety), increased sleep, and enhanced elements of cognitive performance are some of the benefits of moderate or intense physical exercise on cerebral health that happen immediately after moderate or intense physical activity (acute impact). People who engage in more moderate or intense physical activity generally have better mental processes to gain knowledge and comprehension than those who do not. Improvements in cognition, as well as performance, might be expected. For example, standardized assessments of academic achievement and performance on mental ability tests are examples of neuropsychological testing. Processing speed, memory, and executive function are all factors to consider.

PURPOSE: This study aimed to compare the acute effects of different types (treadmill vs. cycle) of moderate-intensity aerobic exercise on cerebral blood flow and cognitive function in young adults.METHODS: By a randomized crossover study design, ten participants were initially assigned to either treadmill exercise (TE; n=5) or cycle ergometer exercise (CE; n=5) and then they performed the other with seven-day wash-out period. Both exercises were implemented at the target heart rate corresponding to 70% of heart rate reserve for 30 minutes. Cognitive function was assessed by the Stroop Color-Word test at pre- and post-exercise. Cerebral blood flow was continuously monitored using near-infrared spectroscopy technique during rest, cognitive function test (CFT), and exercise.RESULTS: There was a significant group by time interaction in tissue saturation index (TSI) (<i>p</i>=.046). Post-hoc analysis presented that TSI at post-exercise CFT was higher than during exercise in TE (<i>p</i>=.02). In both exercises, TSI at pre-exercise CFT significantly increased compared to the resting value (<i>p</i>=.001). Cerebral oxyhemoglobin level was significantly increased during exercise and at post-exercise CFT compared to the resting value in both exercises (<i>p</i><.001). The reaction time for certain cognitive tasks such as color, word with matched color, word with color interference, and color with word interference was improved after both exercises (<i>p</i><.05).CONCLUSIONS: One-bout of moderate-intensity aerobic exercise acutely improves cerebral blood flow and cognitive function even in healthy young adults. Exercise types with the same intensity do not seem to make meaningful difference in the positive effects of aerobic exercise.

Objective cancer-related fatigue(CRF) is the most commonly reported and most distressing symptom in cancer patient.The purpose of this study was to review the effect of exercise intervention on cancer-related fatigue in breast cancer survivors. Methods From 1998 to 2018 in Chinese and English literature of Wanfang Database, Pubmed, SportDiscus and Springer databases, picked out the randomized controlled trials which up to standard. Keywords cancer, exercise, fatigue, etc. were used for systematic search and tracking. 12 experiments were reviewed to analyze the effect differences between exercise intervention and exercise-related fatigue. Results Most interventions use aerobic exercise as the primary form of exercise. Generally, exercise interventions are effective for cancer-related fatigue, but some findings are not. Many studies have shown that moderate intensity aerobic exercise has a significant effect on cancer-related fatigue, with 50-70% heart rate reserve and 3-5 times of exercise per week for at least 30 minutes each time. Exercise methods mainly include walking, yoga, cycling and tai chi. Firstly, Supervised aerobic exercise was statistically more effective than conventional care in improving CRF among breast cancer survivors. It has been shown that group-based, supervised exercise produces positive psychosocial‘side-effects’ due to social interactions, improved self-efficacy, and attention from a trainer. Secondly, Cancer fatigue is divided into acute and chronic fatigue, 18 weeks of exercise intervention can reduce the short-term fatigue, at 36 weeks, baseline levels of fatigue index responses and contrast on the issue of the multivariate statistics. Thirdly, usual-care group were reported that they had been actively engaged in regular exercise before study enrollment. During the exercise intervention, most studies on the control ways are according to the daily life or to take care of, but studies have reported, before intervention, to a high level of 40% in the control group often exercise, exercise also as usual during the intervention, which causes the control to the baseline level is higher, but the intervention group and control group will be difference, no significant difference, lead to the result is invalid. Conclusions First, the exercise intervention of cancer-related fatigue needs to be supervised; second, the exercise intervention is effective for short-term cancer-related fatigue; third, the daily exercise level of the control group will affect the intervention effect.

Based on the fact that taurine can increase lipid metabolism, the objective of the present study was to evaluate the effects of different doses of acute taurine supplementation on lipid oxidation levels in healthy young men after a single bout of fasting aerobic exercise. A double-blind, acute, and crossover study design was conducted. Seventeen men (age 24.8 ± 4.07y; BMI: 23.9 ± 2.57 kg/m²) participated in the present study. Different doses of taurine (TAU) (3 g or 6 g) or placebo were supplemented 90 min before a single bout of fasting aerobic exercise (on a treadmill at 60% of VO2 max). The subjects performed three trials, and each one was separated by seven days. Blood samples were collected at baseline and after the exercise protocol of each test to analyze plasma levels of glycerol and taurine. Lipid and carbohydrate oxidation were determined immediately after exercise for 15 min by indirect calorimetry. We observed that TAU supplementation (6 g) increased lipid oxidation (38%) and reduced the respiratory coefficient (4%) when compared to the placebo (p < 0.05). However, no differences in lipid oxidation were observed between the different doses of taurine (3 g and 6 g). For glycerol concentrations, there were no differences between trials. Six grams of TAU supplementation 90 min before a single bout of aerobic exercise in a fasted state was sufficient to increase the lipid oxidation post-exercise in healthy young men.

The current study examined the relationships between the effects of consuming a caffeine-containing “energy drink” upon (i) short-term maximal performance, (ii) reaction times, and (iii) psychological factors (i.e., mood state, ratings of perceived exertion (RPE), and affective load) and on physiological parameters (i.e., blood pressure and blood glucose). A randomized, double-blind, placebo-controlled, counterbalanced crossover design was implemented in this study. Nineteen male physical-education students (age: 21.2 ± 1.2 years; height: 1.76 ± 0.08 m; body-mass: 76.6 ± 12.6 kg) performed two test sessions: after drinking the “Red Bull’ beverage (RB) and after drinking a placebo (PL). One hour after ingestion of each drink, resting blood glucose and blood pressure were measured and the participants completed the Profile of Mood States questionnaire. Then, after a 5-min warm-up, simple visual reaction time and handgrip force were measured, and the 30-s Wingate test was performed. Immediately after these tests, the RPE, blood glucose, and blood pressure were measured, and the affective load was calculated. Differences between treatments were assessed using two-way repeated measures analyses of variance and paired t-tests, as appropriate. Relationships between the test variables were assessed using Bland–Altman correlations. Significant (i) improvements in peak and mean power output, handgrip force, pre- and post-exercise blood glucose, blood pressure, and vigor and (ii) reductions in reaction times, depression, confusion, fatigue, anger, anxiety, RPE, and affective load scores were observed after RB compared to PL. There were significant correlations of (i) physical performances and reaction times with (ii) RPE, affective load, and pre- and post-exercise blood glucose levels. Gains in peak and mean power were significantly correlated with reductions in fatigue, anxiety (peak power only), and anger (mean power only). The reduction of reaction times was significantly correlated with decreases in confusion and anger and with increases in vigor. Handgrip force and reaction times were significantly correlated with pre- and post-exercise blood pressures. We conclude that RB ingestion has a positive effect on physical performance and reaction times. This effect is related to ergogenic responses in both psychological (i.e., RPE, affective load, and mood state) and physiological (i.e., blood glucose and blood pressure) domains.
