Changes in urinary catecholamine, heart rate, blood pressure and double product during ascent of one-day Mt. Fuji hiking in Japanese young males

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.

Background. The topic relevance is determined by the increasing number of children with congenital heart defect (CHD) who require surgical correction at an early age. For further follow-up it is necessary to determine a functional status of the cardiovascular system (CVS), its adaptation to new conditions of hemodynamics, that is especially important in childhood during the period of morphological and functional changes in the growing organism. Aim. To assess the functional status of the CVS in children with CHD using a test with dosed exercise load (EL) to determine the need for an individual approach to physical rehabilitation.Materials and methods. The study included 80 children, who have been surgically treated for CHD by the age of 1 year. The study population included 32 (40.0%) boys and 48 (60.0%) girls; an average age of patients was 33.5 ± 4.28 months. The control group included 50 conditionally healthy children, with an average age of 35.0 ± 4.1 months; of which 23 (46%) were boys and 27 (54%) were girls. To assess the functional status of the CVS, a test with dosed EL was performed (10 squats in 20 s). Blood pressure and heart rate were measured at rest and after exercise, the double product and the quality of response index were calculated. Results. In children with CHD 2 years after surgery, resting blood pressure was lower compared with healthy children, no significant differences in heart rate between groups were found. The double product in children of the main group was close to above average value. Analysis of hemodynamic changes due to EL showed a more pronounced increase in heart rate and less pronounced increase in pulse pressure and stroke volume in children with CHD after correction, which indicates the adaptation of CVS to EL due to an increase in the rate rather than the strength of heart contractions. The quality of response index in the group of children with CHD corresponded to an irrational reaction to EL. Analysis of CVS responses to the load showed that the most prevalent type was asymptaticotonic one (when there is an increase in heart rate and almost no changes in blood pressure). In the hypertensive type (revealed in a small number of children), there is a significant increase in both heart rate and systolic and diastolic blood pressure. The time of hemodynamics backing up to the baseline parameters did not exceed 5 minutes in both groups, no child complained during the test. Conclusions. In young children who had surgical correction for septal CHD in infancy, blood pressure is characterized by low parameters, that is associated with a possible alteration in the regulation of vascular tone. The predominant type of the CVS response to EL in young children with septal CHD which was corrected in infancy is the asympathicotonic one with a normal period of restoration of hemodynamics to the baseline parameters. The test with EL allows us to individualize the program of physical rehabilitation of young children who had surgery for septal CHD in infancy, taking into account the status of CVS and the initial fitness

Aerobic Conditioning

The response to isometric handgrip exercise (IHE) and isometric quadriceps exercise (IQE) (30% maximum voluntary contraction held 3 min) was studied before and after 5 wk of aerobic training. Training exercises involved only the lower extremities. Seventeen healthy unconditioned males aged 21--35 yr were subjects. During training nine subjects received propranolol in doses that provided a high degree of beta-adrenergic blockade; eight received a placebo. All subjects were tested before training or drug and after training, 3--5 days off drug. With IGE after training, the placebo group had lower maximum heart rate (91 +/- 4 to 79 +/- 5 beats/min, P less than 0.05), systolic blood pressure (151 +/- 5 to 139 +/- 4 mmHg, P less than 0.05), and double product (heart rate x systolic blood pressure) (138 +/- 10 x 10(2) to 110 +/- 7 x 10(2), P less than 0.05). The response to IQE in the propranolol group was unchanged after training. Heart rate, systolic blood pressure, and double product with IHE was unchanged in either group after training. Aerobic conditioning can modify the hemodynamic response to isometric exercise. This effect is specific for the trained muscle group and is prevented by beta-adrenergic blockade.

Water Exercises

Abstract The aim of this study was to compare the cardiovascular and perceived effort of head‐out water exercises selecting different limb strategies and using resistance equipment. Ten young women were randomly assigned to perform at 132 bpm during five minutes different head‐out aquatic exercises: (i) horizontal arms abduction (Ab); (ii) horizontal arms abduction with dumbbells (AbD); (iii) frontal kick (Fk); (iv) frontal kick with leggings (FkLeg), and; (v) aquatic skiing (Ski). Cardiovascular effort was measured by monitoring the heart rate, blood pressure and double product. Perceived effort was assessed by the Borg’s scale. Within‐routines comparison was computed using repeated‐ measures ANOVA followed‐up by the Bonferroni post‐hoc test. Considering the percentage of the maximal heart rate, participants reached 72.88 ± 12.90% in the FkLeg, 65.99 ± 10.91% in the Fk, 62.62 ± 7.20% in Ski, 57.27 ± 11.58% in AbD and 57.12 ± 12.09% in Ab. Comparing exercises, higher heart rates were observed in the FkLeg (140.40 bpm) than Ab (110.30 bpm) or AbD (110.00 bpm). Significant differences were found in the systolic blood pressure when compared to the Fk (120.60 mmHg) and Ab (104.50 mmHg). Double product was higher in the FkLeg (16990) showing a meaningful difference when compared to Ab (11608) or AbD (12001). The highest perceived effort was found in the FkLeg (15.80) with meaningful variations compared to Ab (11.70), the Fk (13.70) and Ski (10.40). Thus, different head‐ out water exercises result in different intensities. The actions by lower limbs promote a higher cardiovascular response, whereas the upper limbs actions trigger a lower exertion. Moreover, exercising the four limbs concurrently seems to be less intense than using only two limbs with an aid.

Heart Rate Analysis

Introduction: Different mechanical behaviors in resistance training can result in certain changes in the cardiovascular system. Objective: To verify the acute behavior of the main cardiovascular variables (heart rate, blood pressure, and double product) when performing resistance training with mono and multiarticular exercises. Methods: 10 male subjects participated in the study (26 ± 4 years; 81 ± 6 kg; 1.77 ± 2 m; 23 ± 1 kg / m2). They performed a test and retest for 8RM in the bench press and crucifix exercises on the machine. After the loads were outlined, they performed the intervention with the exercises, initially with a monoarticular activation containing two sets of 12 repetitions with 50% of the load acquired in the 8RM test of each exercise, using an interval of 60 seconds between one set and another. Additionally, three sets of 8 repetitions (80% 8RM) were performed with an interval between sets of 120 seconds. The execution speed was determined at a moderate level (2s for concentric, 2s for eccentric). It was measured before and during (series 1, series two, and series 3. Named as moments) heart rate exercises using POLAR, model RS800CX Multisport® and blood pressure using OMRON M6 (HEM-7001- E) ®. Then, the double product was calculated using the formula [HR (bpm) X SBP (mmHg)]. Results: In the heart rate analysis, there was an intra-condition difference for moments 1, 2, and 3 compared to rest (p <0.000). In the inter-condition comparison, no differences were observed for rest (p = 0.994) and for moments 1, 2 and 3 (p> 0.999). In systolic blood pressure, intra-conditions, differences were observed for moments 1, 2, and 3 compared to rest (p <0.000). In the inter-condition comparisons, there were no differences between rest (p> 0.999), moment 1 (p = 0.714), 2 (p = 0.999) and 3 (p> 0.999). For diastolic blood pressure, intra conditions, for bench press no significant differences were found for moments 1 (p = 0.331), 2 (p = 0.505) and 3 (p = 0.505) when compared to rest. In the same way it was for the crucifix, wherein the comparison with rest, no difference was observed in moments 1 (p = 0.849), 2 (p = 0.195) and 3 (p = 0.105). In the same sense, no difference was also observed in the comparisons between conditions for rest (p> 0.999), moment 1 (p = 0.999), 2 (p = 0.989) and 3 (p = 0.948). Finally, the double product in intra-condition comparisons found differences between moments 1, 2, and 3 compared to rest (p <0.000). However, in the inter-condition comparisons, no difference was observed at rest (p = 0.999), moment 1 (p = 0.868), 2 and 3 (p> 0.999). Conclusion: It is suggested that resistance training composed of mono and multi-joint exercises offers differences in hemodynamic responses but without differences between the types of mechanics applied by the exercises. Therefore, these results offer a partiality of what can happen with heart rate, blood pressure, and double product.
