Static Stretch Performed After Strength Training Session Induces Hypotensive Response in Trained Men

Area of Science:

• Exercise Physiology
• Sports Science
• Cardiovascular Health

Background:

• Resistance training (RT) is a cornerstone of physical fitness, but its acute effects on blood pressure (BP) require careful consideration.
• Static stretching exercises (SE) are commonly incorporated into training regimens, yet their interaction with RT and subsequent BP responses remain an area of interest.
• Understanding the optimal sequencing of SE and RT is crucial for maximizing training benefits and managing post-exercise cardiovascular adjustments.

Purpose of the Study:

• To investigate and compare the acute effects of three different combinations of passive static stretching exercises (SE) and resistance training (RT) on the blood pressure (BP) response in normotensive trained men.
• To determine if the timing of static stretching (before, after, or between RT sets) influences the post-exercise hypotensive response.

Main Methods:

• Twenty-six trained men (age: 26.1 ± 5.4 years) participated in three experimental conditions in a randomized order: SE performed before RT (SE + RT), SE performed after RT (RT + SE), and SE performed between RT sets (RTSE).
• Subjects completed standardized RT exercises after a 10-repetition maximum assessment.
• Blood pressure was measured for 60 minutes following the RT session in each condition.

Main Results:

• No significant differences in overall BP response were observed between the three experimental conditions (p > 0.05).
• However, the RT + SE condition showed a trend towards not significantly increasing systolic blood pressure (SBP) from baseline (p = 0.07).
• Crucially, the RT + SE condition elicited significant post-exercise hypotensive effects on SBP, observed at 30, 45, and 60 minutes post-exercise (p ≤ 0.04).

Conclusions:

• Performing static stretching exercises immediately after a resistance training session (RT + SE) is an effective strategy for inducing a sustained post-exercise hypotensive response in trained men.
• This specific sequence (RT followed by SE) can help lower systolic blood pressure for up to 60 minutes post-exercise.
• Strength and conditioning professionals can utilize this evidence-based approach to optimize training protocols for blood pressure management.
