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.

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

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.
Analysis of Blood Pressure after and of Exercise Training Competitor
International Journal of Sports and Exercise Medicine, 2021
Are called concurrent training programs that combine strength training and aerobic endurance in the same training session. This study aimed to verify the behavior of blood pressure during and after a training session competitor. We studied 10 subjects aged 30.8 ± 12.8 (19 to 53 years) (4 hypertensive and normotensive 6) of both genders (5 men and 5 women). The statistical analysis was performed using software (Primer for Windows, version 4.0.0.0, McGraw-Hill, USA) using paired t-test, giving the significance level of p < 0.05 for SBP and DBP. The results obtained in this study indicate HPE for 60 minutes when performed concurrent training in question and suggests a reduction in BP similar to aerobic training, but with a slightly greater reduction in DBP.
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 aim of this study was to identify hypertension (HT) in karate competitors (KCs) in high intensity exercise. Values were compared with an exercise control group (EC). The 84 subjects were randomly divided into two groups: KC and EC. Resting blood pressure (BP) was measured the day before and immediately precompetition. A further three measurements were taken postexercise for all subjects at 1-, 2-, and 8- minute intervals. At rest, day one, mean BP of KC was 134/84 ± 3/2 mmHg vs. EC, 124/72 ± 1/2 mmHg and on day 2, was 141/79 ± 3/2 mmHg vs. EC, 125/72 ± 1/2 mmHg, respectively. Eight minutes postcompetition, BP of KCs was 140/77 ± 2/1 mmHg vs. EC 135/75 ± 2/1 mmHg. High blood pressure (HBP) was recorded in 60.5% of KCs on day 2, and essential HT that required medical therapy was subsequently diagnosed in 5% of KCs. Five percent of EC also had HBP, but subsequent medical examination reported normal values.
Resistance exercise and acute blood pressure responses
The Journal of sports medicine and physical fitness, 2015
Compare the acute hemodynamic and cardiovascular responses of high load/low repetition resistance training (RT) to low load/high repetition RT. Thirteen healthy men performed four sets of 4 repetition maximum (RM) and 20RM leg--extensions without breath--holding. The RT was conducted in a randomized order and with 48 hours between bouts. Non--invasive beat--to--beat systolic and diastolic blood--pressure (SBP/DBP) was measured on the finger, while non--invasive cardiac output (CO) was assessed beat--to--beat by impedance--cardiography. Mean ± SD resting SBP/DBP and CO were 126 ± 14/73 ± 9 mmHg and 5.6 ± 9 L min --1 , respectively. Exercise SBP/DBP values increased to 154 ± 22/99 ±18 and 203 ± 33/126 ± 19 mmHg following 4RM and 20RM RT, respectively (compared to rest, all;; p < 0.001), and 20RM SBP/DBP values were higher than 4RM values (both, p < 0.001). The SBP increased from the first to the fourth set of exercise following the 20RM load (p < 0.01), but not so for the 4RM...
Finger Blood Pressure During Leg Resistance Exercise

However, because of its invasive characteristics, this technique is not feasible in clinical settings, limiting research and practical guidelines. As an alternative, the indirect auscultatory BP measurement technique was tested for this purpose, but it underestimated the intra-arterial BP levels by more than 13 % . The non-invasive BP measurement based on fi nger photoplethysmographic (FPP) technique is a valid method to assess BP at rest and during aerobic exercise . However, to the best of our knowledge, up to now no previous study has compared FPP BP values with the ones obtained with intra-arterial measurement during resistance exercise. As in clinical settings cardiovascular risk is mainly attributed to a huge increase in BP, it is especially important to establish this comparison in subjects who achieve higher BP levels during this kind of exercise, which has been reported in hypertensive individuals . Therefore, the aim of the present study was to compare FPP and intra-arterial BP values and Abstract ▼

The purpose of this study was to examine post-exercise hypotension (PEH) responses to three diff erent resistance exercise velocities in female athletes. The 13 female subjects with experience of resistance training performed a series of resistance exercises with 80% of one repetition maximum for 3 sets with diff ering in velocity of movements: fast movement (FM; 1-second eccentric and 1-second concentric actions), moderate movement (MM; 1-second eccentric and 2-second concentric actions) and slow movement (SM; 2-second eccentric and 4-second concentric actions). After completing each training session, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were taken every 10 min for a period of 60 min of recovery. The results indicated signifi cant increases in SBP at 10th min post-exercise in comparison to baseline. After 60-min recovery, all conditions showed statistically signifi cant decreases in SBP when compared with pre-exercise. In all measured moments, there were no signifi cant diff erences among experimental sessions in post-exercise levels of SBP and DBP. Therefore, resistance training with FM, MM, and SM can induce increases in SBP after exercise, whereas after 60-min recovery, can induce decreases in SBP or post-exercise hypotension.
