Background Resistance training has been introduced in cardiac rehabilitation to give more benefit than traditional training. Haemodynamic evaluation of cardiac patients to resistance training has generally consisted of continuous HR monitoring and discontinuous blood pressure measurements. Design and methods Blood pressure (BP) and heart rate (HR) responses to resistance training were evaluated using continuous monitoring (Finapres) during low (four sets of 17 repetitions at 40% of the one-repetition maximum strength [1-RM]) and high intensity resistance training (four sets of 10 repetitions at 70% of 1-RM) on a leg extension machine in 14 patients who participated in a rehabilitation programme. Work volume was identical in the low-and high-level resistance training. Results The HR and systolic blood pressure (SBP) during low intensity resistance training were always larger than during high intensity (P < 0.001). Peak SBP increased from set 1 to set 3 and 4 during both low and high intensity resistance training (P < 0.05). Peak HR was larger in set 4 (95 ± 11 bpm) than in set 1 only during low intensity resistance training (91 ± 12 bpm) (P < 0.05). One-minute recovery periods did not allow a return to baseline HR and SBP during both low and high intensity modalities. Conclusions The SBP and HR responses to resistance training are related to the duration of exercise. Sets with r 10 repetitions of high intensity should be preferred to longer sets with low intensity. Pauses between exercise sets should exceed 1 min. Blood pressure should be measured during the last repetitions of the exercise set.

Background: The isolated effect of resistance training (RT) on heart rate variability (HRV) and blood pressure (BP) is crucial when prescribing suitable training programmes for healthy individuals. Objective: The purpose of this study was to compare BP and HRV responses in physically active men after an acute RT session with loads of 5-, 10- or 15-repetition maximums (5RM, 10RM and 15RM). Method: Eighty-one men (age: 21.6±1.1yr; body mass: 74.1±5.8 kg; height: 175.3 ±7.1cm) who performed moderate to vigorous physical activities for at least 30 min a day on most days of the week participated in this study. After the of 5RM loads for the bent-over row (BR), bench press (BEP), Dead-lift (DL) and squats (SQ), participants were divided into three training load groups (15RM = GrpL, 10RM = GrpM or 5RM = GrpH). During the experimental session, each group (n=27) performed 3 sets for each of the four exercise, with 2-min rest intervals between sets and exercises with their assigned training l...

OBJECTIVE: The aim of this study was to describe blood pressure responses during resistance exercise in hypertensive subjects and to determine whether an exercise protocol alters these responses. INTRODUCTION: Resistance exercise has been recommended as a complement for aerobic exercise for hypertensive patients. However, blood pressure changes during this kind of exercise have been poorly investigated in hypertensives, despite multiple studies of normotensives demonstrating significant increases in blood pressure. METHODS: Ten hypertensive and ten normotensive subjects performed, in random order, two different exercise protocols, composed by three sets of the knee extension exercise conducted to exhaustion: 40% of the 1-repetition maximum (1RM) with a 45-s rest between sets, and 80% of 1RM with a 90-s rest between sets. Radial intra-arterial blood pressure was measured before and throughout each protocol. RESULTS: Compared with normotensives, hypertensives displayed greater increases in systolic BP during exercise at 80% (+80±3 vs. +62±2 mmHg, P<0.05) and at 40% of 1RM (+75±3 vs. +67±3 mmHg, P<0.05). In both exercise protocols, systolic blood pressure returned to baseline during the rest periods between sets in the normotensives; however, in the hypertensives, BP remained slightly elevated at 40% of 1RM. During rest periods, diastolic blood pressure returned to baseline in hypertensives and dropped below baseline in normotensives. CONCLUSION: Resistance exercise increased systolic blood pressure considerably more in hypertensives than in normotensives, and this increase was greater when lower-intensity exercise was performed to the point of exhaustion.

This aim of the present study was to analyze the hemodynamic responses during resistance exercise performed at different intensities and with different recovery intervals. This study was conducted on twenty-four apparently healthy male individuals (25.50 ± 3.72 years and 76.50 ± 4.50 kg) experienced in strength training. The volunteers performed a 1RM test to determine the training load for the study. Blood pressure and Rate Pressure Product were measured before and at the end of the exercise training. The only significant difference observed was in SBP during strength training at 70% intensity (121.7 ± 8.68, p = 0.039), which was lower than SBP at the remaining intensities of 80% (126.3 ± 7.11) and 90% (127.1 ± 7.51). It was concluded that strength training performed at different intensities and recovery intervals did not significantly alter most variables, changing only the SBP due to the intensity employed.
Intra‐Arterial Blood Pressure Traits During and After Heavy Resistance Exercise in Healthy Males
Translational Sports Medicine, 2019
Cardiovascular diseases are responsible for one third of global mortality, accounting for approximately 17 million deaths each year. 1 Hypertension is a major risk factor associated with the development of cardiovascular diseases. 1,2 Approximately 40% of individuals above the age of 25 are diagnosed with hypertension worldwide, 1 and thus, actions for lowering high blood pressure (BP) are of great importance. Hypertension may be modified, or even normalized, by nonpharmacological treatments. 3 In addition to aerobic exercise as a well-established and recommended treatment of hypertension, 4,5 resistance exercise (RE) has been recommended as a supplement due to its favorable adaptations in musculoskeletal function and in cardiometabolic risk factors. 4,6,7 However, the studies of the influence of RE on resting BP are limited and conflicting, 8 and additional research to expand the limited data on the BP-lowering effect of RE is needed. 5
Effect of different resistance exercise methods on post-exercise blood pressure
2008
Pr re es ss su ur re e ABSTRACT Int J Exerc Sci 1(4) : [153][154][155][156][157][158][159][160][161][162] 2008. The aim of the present study was to evaluate the post-exercise blood pressure (BP) responses to two different methods of resistance exercise (RE, traditional multiple set and tri-set). Young adult men (n = 30, 19.6 ± 0.7 years old; 76.0 ± 2.7 kg; 178.2 ± 6.7 cm; 90.5 ± 5.8 MBP) with six months of previous experience in RE were selected. The volunteers were randomly assigned into three groups (n = 10, each group): non-exercised control group (CON); multiple set group (MS); and a tri-set group (TRI). The TRI group performed three consecutive exercises (3 sets of 10 repetitions with 70% of 1RM and 1 minute of rest interval after the three exercises for the same muscle group) in the following order: bench press, cross-over and peck-deck and lat pull-down, seated cable row and barbell row. The multiple set group performed 3 sets of 10 repetitions for the same exercises, but with 1 minute rest interval between each set and exercise. After the exercise sessions and control situation, individuals remained seated for BP measure every 5 minutes up to 90 minutes. The repeated measures analysis of variance (ANOVA) (2 groups by three time points) was used, followed by post-hoc Bonferroni test, for p≤0.05. There were no significant alterations for systolic and diastolic blood pressure compared with the CON group and in the moments after exercise. Heart rate was increased after exercise for both exercised groups in all post-exercise measures compared with baseline. RE method (MS or TRI) exerted no influence on post-exercise blood pressure. Post-exercise induced hypotension may require the recruitment of larger muscle groups, such as those of the lower limbs.

The purpose of the present study was to correlate the acute and chronic decrease in blood pressure (BP) following resistance training (RT). 13 normotensive women (18-49 years) completed an acute whole body RT session with 3 sets of 10 repetitions at 60% 1RM and then 8 weeks of RT as follows: 3/week, 3 sets of 8-12 repetitions maximum. Systolic (SBP) and diastolic BP (DBP) were measured up to 60 min and 24 h following RT (acute and chronic). The greatest acute decrease of SBP (108.5±7.0 mmHg) and DBP (71.5±6.4 mmHg) values over the 60-min period were reduced compared to pre-exercise (117.3±11.7 and 79.3±8.2 mmHg, respectively; p<0.05). The chronic effect on resting BP was observed only for those presenting acute post-exercise hypotension (PEH). The change in both SBP and DBP following acute RT was correlated with the chronic change in resting SBP and DBP (r>0.5; p≤0.05). The change in 24 h BP after acute RT was correlated with the chronic reduction in SBP (r=0.74) and DBP (r=0....
Blood pressure assessment during resistance exercise: comparison between auscultation and Finapres
Blood Pressure Monitoring, 2007
Objectives The objective of this study was to test whether the auscultatory method and Finapres provide similar readings for blood pressure response during two resistance exercise protocols of different intensities, and to gain some insight into whether auscultation can be used to monitor cardiovascular stress during resistance exercise. Methods Fourteen patients performed six and 15 maximum repetitions (six and 15, respectively) of one-leg knee extension on different days. Blood pressure (BP) was measured simultaneously with the two methods at rest and during the last repetition of the protocols. Results Neither the systolic blood pressure (SBP) nor the diastolic blood pressure (DBP) differed between methods, both at rest and at six maximum repetitions. Conversely, Finapres recorded higher systolic blood pressure at 15 maximum repetitions (168.8 ± 21.7 mmHg) than auscultation (147.0 ± 14.5 mmHg; P < 0.001). In addition, the blood pressure values obtained by both methods in each exercise protocol (six and 15 maximum repetitions, respectively) were ranked in tertiles and also treated by the gamma (c) nonparametric correlation. We observed a high probability for patients to be ranked on the same tertile regardless of the method used, at both six maximum repetitions (SBP = 0.80, DBP = 0.97) and 15 maximum repetitions (SBP = 0.88, DBP = 0.92). High association between methods was also observed by simple regression when measurements taken at rest and at each intensity were analyzed altogether for both SBP (r = 0.95, r 2 adjusted = 0.89) and DBP (r = 0.79, r 2 adjusted = 0.62). Conclusion Auscultation provides lower BP values than Finapres, especially at the end of a set including 15 maximum repetitions. The former, however, seems appropriate to assess the relative cardiovascular stress imposed by different protocols of resistance exercise.

Hypotensive effects of resistance exercises performed at different intensities and same work volumes
The aim of this paper was to compare the effects of two sequences of resistance exercises (RE), with different intensities but same training volume, on post-exercise blood pressure responses. Sixteen young subjects with previous experience in RE were evaluated during three non-following days in chest press, legpress, pulley pull down, leg curl, shoulder press, and biceps curl. On the first day, the load associated with six maximal repetitions (6RM) were determined for each exercise. On the second day, three sets of 6RM were performed (SEQ6), with a two minute interval between the sets. On the last day, the same procedure was repeated, but using 12 repetitions with 50% of 6RM load (SEQ12). Rest BP was measured before the sequences by auscultatory method. Post-exercise resting BP was measured each 10 minutes by ambulatory BP monitoring during 60 minutes. The magnitude and duration of BP variability were compared by repeated ANOVA measures followed by Tuckey post-hoc test (p < 0.05). A significant reduction in diastolic blood pressure (DBP) was observed in the first 20 minutes after SEQ12, but not after SEQ6. SEQ12 elicited significant decline in systolic blood pressure (SBP), at least during the first 50 minutes after the exercise, while significant reductions were observed in all measures after SEQ6. There were no significant differences between the absolute values of DBP and SBP after both sequences. In conclusion: a) RE had hypotensive effects on blood pressure, main-ly SBP; b) the absolute decline of SBP seem not to be influenced by different interactions between workload and number of repetitions; c) higher workloads seem to extend the total time of SBP post-exercise reduction; d) the number of repetitions seems to have more influence on DBP than SBP, but for a short period of time.
Acute resistive exercise does not affect ambulatory blood pressure in young men and women
Medicine and Science in Sports and Exercise, 2001
ROLTSCH, M. H., T. MENDEZ, K. R. WILUND, and J. M. HAGBERG. Acute resistive exercise does not affect ambulatory blood pressure in young men and women. Med. Sci. Sports Exerc., Vol. 33, No. 6, 2001, pp. 881-886. Purpose: Resistive exercise elicits a pressor response that results in a dramatic increase in blood pressure (BP) during the exercise. However, it is not known if the BP elevation persists after resistive exercise. Methods: This study examined the effects of an acute resistive exercise session on 24-h ambulatory BP in sedentary (5 men, 6 women), resistance-trained (6 men, 6 women), and endurance-trained (4 men, 6 women) young subjects (age 22 Ϯ 3.2 yr) with normal BP. Two 24-h ambulatory BP recordings were made on each subject, one after two sets of resistive exercise on 12 weight machines and one after 48 h without prior exercise. Results: Systolic, diastolic, and mean arterial BP and heart rate (HR) were not different in the hours after and for up to 24 h after the single resistive exercise session compared with the control day. There also was no difference in the ambulatory BP or HR response after the single session of resistive exercise based on the training status of the subjects. Conclusion: Thus, the elevated BP that occurs during resistive exercise does not persist in the 24 h after acute resistive exercise in sedentary, resistance-trained, or endurance-trained, young, normotensive men and women.
