The regular practice of physical exercise, primarily aerobic, has been recommended as a component of the non-pharmacological treatment for dyslipidemias. However, there is a lack of studies in the literature comparing the acute effects of different aerobic exercise models (continuous and interval) on triglycerides concentrations. The purpose of the present study was to analyze the magnitude of change on triglycerides concentrations after a single session of interval and continuous exercise in persons with dyslipidemia. This study was a randomized crossover clinical trial. Fifteen volunteers performed two different aerobic sessions, a continuous and an interval session. The intensity of the continuous session was maintained between 85-90% of the heart rate at anaerobic threshold (HRAT). The interval session consisted of 9 sets of 4 minutes at 85-90%HRAT followed by one minute below 85%HRAT. Triglycerides concentrations were assessed before, immediately after and at the end of 30 minutes after all sessions. Both sessions models resulted in alterations in triglycerides concentrations immediately after exercise (p = 0.005), without difference between them (p = 0.446). Continuous session increased triglycerides concentrations by 34.9% from pre-exercise to immediately post-exercise and the interval session, by 7.9%. Thirty minutes after exercise, triglyceride concentrations showed no significant difference in relation to the pre-exercise and immediately after exercise moments in both session models. Therefore, it is concluded that aerobic exercise promotes responses in triglycerides concentrations of dyslipidemic patients, independently of the exercise method, either continuous or interval.

Abstract Introduction: Tai-Chi-Chuan and Yoga have becoming popular practices. However is unclear the cardiovascular effects, and if they present similar behavior to aerobic and resistance sessions. Objective: To evaluate the cardiovascular responses during the session and post-exercise hypotension (PEH) of Tai Chi Chuan (TS) and Yoga (YS) in comparison to aerobic (AS) and resistance (SR) exercises. Methods: Fourteen young women (22.3 ± 2 years) apparently healthy performed four sessions (AS, RS, TS and YS). The heart rate (HR), systolic (SBP) and diastolic blood pressure (DBP) were recorded at resting, during (every 10 minutes) and until 50 minutes of recovery. Results: AS, RS, TS e YS showed significant increase in HR compared to resting.AS at 10, 30 e 50 minutes in relation to RS, TS e YS. The RS in relation to TS and YS at 10, 30 and 50 minutes. No significant difference between TS and YS. SBP was significantly increased in AS, RS, TS e YS at 10, 30 e 50 minutes during the session, in relation to rest. AS was significantly higher at 30 e 50 minutes than RS and higher than TS and YS at 10, 30 e 50 minutes. No significant difference in DBP. For PEH, AS, RS and TS significantly reduced at 10, 30 and 50 minutes. YS reduced at 50 minutes. No significant diastolic PEH. Conclusion: TS and YS showed as safe alternatives of exercising in the normotensive young adult woman, despite having lower values, they promote similar hemodynamic behavior to AS and RS.

Background: Age-related change in autonomic nerves covers parasympathetic function decrease that hampers heart rate (HR) control.  The effective attempt to improve autonomic nervous function for elderly is routine exercise, however exercise duration among elderly is not always standardized. This study is aimed to compare the effect of different exercise duration to post-exercise Heart Rate Recovery (HRR) between two elderly groups with the same frequency, intensity, type criteria of routine exercise. Method: Method was cross-sectional study which compared exercise duration of standardized group (3x90 minutes/week) and unstandardized group (3x30 minutes/week). Group 1 was elders with standardized duration from Healthy Heart Club and Group 2 was elders who take unstandardized duration from Elderly Home in Bandung city. Each group consisted of 43 elders and data were collected in July-August 2019. After one hour of medium intensity exercise, all respondents were examined for resting HR (HRrest), maximum HR (HRmax), one minute post-exercise HR, and four minutes post-exercise HR. HRR was obtained by subtracting HRmax by one minute post-exercise HR and normal if  > 12 bpm. Analysis data was done by SPSS with Mann-Whitney U Test, Fisher Chi Square and Logistic regression. Result: Most of respondents were 60-69 years old and female. Respondents in unstandardized group were more low education, hypertension and smoking. The HRrest of both groups was categorized as normal but increased greater (30x/min)  in standardized group. The result showed a significant difference in comparation of median HRR (p=0.001) and number of normal and abnormal HRR (p=0.001) between both groups. Gender, smoking and standardized duration of exercise associated with abnormality of HRR, elders who take unstandardized duration have 12.7 times risk to get abnormal HRR. Conclusion: Routine exercise for elderly is recommended in standardized duration with minimal 150 minutes per week in order to increase post-exercise HRR.

ABSTRACT This study aims to verify the effect of the restriction of the ventilatory flow on HR, RPE, and power during HIT-test performed by healthy women. The participants (n=8) underwent HIT-test without and with ventilatory flow restriction. HR, power, and RPE was measured. HRpost showed no significant difference between conditions (p=0,053). The average power presented higher values in the condition without the restriction of ventilatory flow (619,51±144,33W; 565,99±108,43W; p=0,001), but without differences in the fatigue index (p=0,383). In both conditions, increases in RPE were observed during the efforts (p<0,001). It is concluded that HR and RPE did not suffer acute effects from the restriction of ventilatory flow; however, the average power is decreased during HIT-test.

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.

AbstractTo investigate the effect of acute capsaicin (CAP) supplementation on time to exhaustion, physiological responses and energy systems contribution during continuous high-intensity exercise session in runners. Fifteen recreationally-trained runners completed two randomized, double-blind continuous high-intensity exercises at the speed eliciting 90% V̇O2peak (90% s V̇O2peak), 45 minutes after consuming capsaicin or an isocaloric placebo. Time to exhaustion, blood lactate concentration, oxygen consumption during and 20-min post-exercise, energy systems contribution, time to reach V̇O2peak, heart rate and the rate of perceived exertion (RPE) were evaluated. There was no significant difference between conditions for time to reach V̇O2peak (CAP:391.71±221.8 vs. PLA:298.20±174.5 sec, ES:0.58, p=0.872), peak lactate (CAP:7.98±2.11 vs. PLA:8.58±2.15 µmol, ES:−0.28, p=0.257), time to exhaustion (CAP:654.28±195.44 vs. PLA:709.20±208.44 sec, ES:−0.28, p=0.462, end-of-exercise heart rate (CAP:177.6±14.9 vs. PLA:177.5±17.9 bpm, ES:−0.10, p=0.979) and end-of-exercise RPE (CAP: 19±0.8 vs. PLA: 18±2.4, ES: 0.89, p=0.623). In conclusion, acute CAP supplementation did not increase time to exhaustion during high-intensity continuous exercise nor alter physiological responses in runners.

Background and objectives: As a result of ergogenic properties, caffeine has been increasingly taken prior to physical exercise, yet its effects on post-exercise recovery, considering the differences in the cardiorespiratory capacity of the individuals, has not yet been studied or fully elucidated. Optimizing the post-exercise recovery can convey advantages to physical activity practitioners. We evaluated the acute effects of caffeine on heart rate (HR) autonomic control recovery following moderate aerobic exercise in males with different cardiorespiratory capacities. Materials and Methods: We split young adult men into two groups based on their various oxygen consumption peaks (VO2 peak): (1) Higher VO2 (HO): Sixteen volunteers, peak VO2 > 42.46 mL/kg/min and (2) Low VO2 (LO): Sixteen individuals, VO2 < 42.46 mL/kg/min). The volunteers were submitted to placebo and caffeine protocols, which entailed 300 mg of caffeine or placebo (starch) in capsules, followed by 15 min of rest, 30 min of moderate exercise on a treadmill at 60% of the VO2 peak, followed by 60 min of supine recovery. Heart rate variability (HRV) indexes in the time and frequency domains were examined. Results: Effect of time for RMSSD (square root of the average of the square of the differences between normal adjacent RR intervals) and SDNN (standard deviation of all normal RR intervals recorded in a time interval) was achieved (p < 0.001). Significant adjustments were observed (rest versus recovery) at the 0 to 5th min of recovery from exercise for the LO during the placebo protocol and at the 5th at 10th min of recovery for the caffeine protocol. For the HO in both procedures we found significant alterations only at the 0 to 5th min of recovery. Conclusion: Caffeine delayed parasympathetic recovery from exercise in individuals with lower cardiorespiratory capacity.

Abstract Background Nowadays, it is generally assumed that non-pharmacologic pain relief in preterm infants is an important measure to consider. Research findings suggest that familiar odors have soothing effects for neonates. The aim of this study was to compare the effect of maternal breast milk odor (MBMO) with that of another mother’s breast milk odor (BMO) on the behavioral responses to pain caused by hepatitis B (HB) vaccine injection in preterm infants. Methods This single-blind randomized clinical trial was performed over the period between February 2019 and March 2020 in the neonatal intensive care unit of Babol Rouhani Hospital, Iran. Ninety preterm infants, who were supposed to receive their HB vaccine, were randomly assigned into three groups: MBMO (A), another mother’s BMO (B), and control with distilled water(C). Oxygen saturation (SaO2), blood pressure (BP) and heart rate (HR) were recorded for all participants through electronic monitoring. In addition, premature infant pain profiles (PIPP) were determined through video recording for all three groups during intervention. The chi-square, ANOVA and ANCOVA were used for analyzing the data, and P < 0.05 was considered significant in this study. Results No significant differences were found between the three groups in mean ± SD of HR, BP, and Sao2 before the intervention (P > 0.05). After the intervention, however, the means for heart rate in groups A, B, and C were 146 ± 14.3, 153 ± 17.5 and 155 ± 17.7, respectively (P = 0.012). Moreover, the means for PIPP scores in groups A, B and C were 6.6 ± 1.3, 10 ± 2, and 11.4 ± 1.9, respectively (P < 0.001). There was no significant difference found between groups in their means of SaO2, systolic and diastolic blood pressure after the intervention (P > 0.05). Conclusions The results indicate that stimulation with MBMO is effective in reducing pain in preterm infants; therefore, it can be postulated that this technique can be considered in less invasive procedures such as needling.

Jiu-jitsu is a sport that involves different techniques to lead the opponent to submission, combats are characterized by intermittent efforts with changes in important cardiovascular variables. Thus, the aim was to evaluate the acute effects of a simulated jiu-jitsu match on blood pressure (BP) and the double product (DP) of fighters in the master category. The heart rate (HR), BP, and DP of six experienced fighters were measured, before and after the protocol. The combat consisted of four six-minute sessions with intervals of three minutes for recovery and measurement of the variables. Measurements were taken every 15 minutes, after the end of the fight. An increase in systolic (SBP) and mean BP (MAP) was observed after the last session. After 30 minutes, there was a decrease in MAP and SBP, until the end of the protocol. Diastolic BP (DBP) decreased after 30 minutes, returning to baseline after 45 minutes post-combat. HR remained high until 30 minutes of recovery. Despite the increase greater than 280% of the DP, verified immediately after the fight, 15 minutes of recovery was sufficient for this index to return to baseline values. The study shows that a jiu-jitsu match causes a significant increase in SBP and MAP, HR and PD with subsequent arterial hypotension.Keywords: cardiovascular physiological phenomena, blood pressure, martial arts.

Lifestyle, unhealthy eating patterns, and low physical activity become trigger factors of obesity. Therefore, lifestyle modification with an exercise-based nonpharmacological approach is one of the strategies for combat obesity. This study aims to analyse the response of moderate-intensity interval and continuous exercise to irisin level increasing pattern on the obese female. A total of 21 obese females were enrolled in this study and given moderate-intensity interval exercise (MIIE) and moderate-intensity continuous exercise (MICE). ELISA was used to quantify the serum level of irisin in all samples. Statistical analysis was performed using one way-ANOVA and Tukey’s honestly significant difference (HSD) post hoc test. Mean irisin levels of pre-exercise at control (CON), MIIE, and MICE were 3.26±1.28l, 3.44±0.56 and 3.89±1.08 ng/ml, respectively (P=0.519). The mean irisin level of 10 min post-exercise was 2.99±0.86 ng/ml at CON, 4.82±1.01 ng/ml at MIIE, and 5.99±1.27 ng/ml at MICE (P=0.000). The mean irisin levels of 6 h post-exercise were 3.04±0.60, 4.56±0.87, and 5.73±1.02 ng/ml at CON, MIIE, and MICE, respectively (P=0.000). The mean irisin level of 24 h post-exercise was 3.04±0.91 ng/ml at CON, 4.64±0.69 ng/ml at MIIE, and 5.69±1.53 ng/ml at MICE (P=0.002). We conclude that the post-exercise serum irisin level increased in both MICE and MIIE subjects, and the post-exercise serum irisin level maintained higher in the MICE than in the MIIE in the obese female subjects.
