The influence of the order between resistance and stretching exercises on the hemodynamic response

Abstract

The present study compared the acute effect of different combinations of resistance training (RT) and static stretching (SS) on the heart rate (HR), rate pressure product (RPP) and oxygen saturation (SpO2) of participants. This is a cross-over methodological design carried out in five visits on nonconsecutive days, which always occurred at the same time of day. Twelve trained young men were randomly divided, using counterbalanced and alternate assignments, into three experimental situations: a) horizontal abduction of the shoulder, knee flexion and hip abduction before the bench press and leg extension machine, respectively (SS + RT); b) bench press and leg extension machine before horizontal abduction of shoulder, knee flexion and hip abduction, respectively (RT + SS); c) bench press and leg extension machine, exclusively (RT). Analysis of variance (ANOVA) with repeated measures showed significant differences in the SS+RT group when the variables were compared at rest (pre) and immediately after the exercises (post): HRpre vs. HRpost (p = 0.000) and RPPpre vs. RPPpost (p = 0.000). In the intergroup comparisons, significant differences were detected between the SS+RT and RT+SS experimental situations exclusively during the post period for the RPP (p = 0.041) and SpO2 variables (p = 0.002). The combined use of SS and RT significantly changed the intragroup cardiovascular responses by increasing the HR and RPP and decreasing the SpO2. However, the values were lower in the intergroup comparisons when the stretching exercises were performed both before and after RT, although no significant differences were found from a cardiovascular safety point of view.

Effect of 24 sessions of stretching exercises performed before resistance exercises on hemodynamic responses

“…The two previous studies that assessed the acute effects of SE and SE+RE on hemodynamic responses were conducted by Da Silva et al ( 2019) and Souza et al (2019). Both studies involved a group of volunteers who performed 6 SE (pectoral, dorsal, deltoids, quadriceps, hamstrings, and gluteus) followed by 6 RE (bench press, front pull up, shoulder press, leg press 45, leg extension, and Leg curl machine) (Da Silva et al, 2019;Souza et al, 2019). In Da Silva et all.…”

“…The interaction between different combinations and sequences of RE and SE on acute cardiovascular responses has been explored in a series of elegant studies studies (G. da S. Araujo et al, 2019;G. S. Araujo et al, 2018;Costa e Silva et al, 2019;da Silva et al, 2019;Santos et al, 2014;SOUSA et al, 2019). reported increased acute cardiovascular responses when SE was combined with RE, assessed using the double product.…”

Acute effect of stretching performed before a resistance exercise session using different intervals on maximum repetitions performance in recreationally trained adults

“…The physical fitness components involve body composition, aerobic profile, as well as neuromotor and neuromuscular conditioning (GARBER et al, 2011). Strength and flexibility training, when performed in conjunction, highlight researchers' interest in neuromuscular performance (FIGUEIREDO et al, 2016;GOMES et al, 2011;PAZ et al, 2012;RIBEIRO et al, 2014;SÁ et al, 2015) and cardiovascular effects (ARAUJO et al, 2019;COSTA e SILVA et al, 2019;da SILVA et al, 2019;SANTOS et al, 2014). Stretching exercises (SE) have been widely performed before physical and sports activities by both physical exercise practitioners and athletes.…”
