Detailed description
The effect of individual variants of agonist-antagonist and traditional agonistic resistance training on cardiovascular parameters in individuals with normotension and hypertension. Participants with normotension and hypertension (1 stage of hypertension), adult: 40 - 63 years old, physically active - no professional sportsman. Participants with fluctuating blood pressure, with type 1 and type 2 diabetes mellitus, after a myocardial infarction, after a stroke, with an infectious disease, with grade 3 obesity, with hypertension II. - IV. degrees and individuals suffering from dizziness during exercise are excluded. What does the study involve? 1. Cardiovascular parameters - SBP, DBP, HR, PWV and augmentation index are measure by Arteriograph (TensioMed, Budapest, Hungary) at baseline, during and after training sessions. 2. Body composition - Body composition is measured by InBody370S in Pavel Kolar´s Centre of Physical Medicine before intervention. 3. Blood tests for heart disease - tests help determine the risk of heart diseases. it can be very helpful in assessing health. Total cholesterol, LDL, HDL, triacylglycerols, CRP, glucose are measured by NEXTCLINICS Czech a.s. before intervention 4. Training intervention: Resistance training: 75% 1RM, 10 reps, 3 sets, 2 min rest between sets and exercises, 16 exercises (8 lower body exercise + 8 upper body exercise), Agonistic vs Agonistic-antagonist resistance training, freeweight + cable machines according to ACSM's Guidelines for Exercise Testing and Prescription, 11th Edition A. Resistance training protocol: 1. Agonistic RT - upper body 2. Agonistic RT - lower body 3. Agonist-Antagonist - upper body 4. Agonist-Antagonist - lower body B. Aerobic training: 60% SF max, 4 x 10 min, 2 min rest between sets 5. Intraabdominal wall tension testing during resistance training - correction of respiratory stereotype during exercise. Abdominal wall tension is measured by OHMBelt (Nilus Medical LLC) in Pavel Kolar´s Centre of Physical Medicine before, during and after resistance training. 6. The intensity of the exercises is determined by the Borg rating of perceived exertion (RPE) during resistance training. 7. Handgrip is measured by Takei (TKK 5401, Japan) before intervention. The Harvard Step Test is used to measure a clients aerobic fitness before intervention. 8. Repetition testing is assessing the strength capacity of individuals in non-laboratory environments: 15 RM, 10RM, 5 RM, 1 RM tests in Pavel Kolar´s Centre of Physical Medicine and the Faculty of Physical Education and Sport, Charles University before intervention. Benefits: health assessment, physical fitness testing, professional supervision of training. Potential disadvantages: soreness and muscle strain, fatigue, dizziness, feeling sick. The study is run in Pavel Kolar´s Centre of Physical Medicine and the Faculty of Physical Education and Sport, Charles University. The study began in April 2022 and will run until December 31, 2023. Agonist-Antagonist resistance training with 75% 1 RM induces an similar decrease in systolic and diastolic blood pressure values after training sessions at the p\<0.05 level, as aerobic (control) training in normotensive and hypertensive individuals (1 stage of hypertension). Alternative hypothesis H1: Agonistic-Antagonist resistance training with 75% 1 RM will result in a smaller increase in systolic and diastolic blood pressure values after training sessions at the p\<0.05 level, compared to traditional resistance training in sets in normotensive and hypertensive subjects (1 stage of hypertension). Agonistic resistance training with 75% 1 RM will induce a similar increase in pulse wave velocity during the training sessions at the p \<0.05 level as aerobic (control) training in normotensive and hypertensive subjects (1 stage of hypertension). Alternative Hypothesis H2: Agonistic resistance training with 75% 1 RM will result in a statistically significantly greater increase in pulse wave velocity values during the training sessions at the p \<0.05 level compared to traditional resistance training in sets in normotensive and hypertensive subjects (1 stage of hypertension). Isolated exercises induce a similar increase in systolic and diastolic blood pressure values during resistance training in normotensive and hypertensive individuals (1 stage of hypertension) as aerobic (control) training. Alternative hypothesis H3: Complex/multi-joint exercises will lead to statistically significantly higher increases in systolic and diastolic blood pressure values in normotensive and hypertensive subjects (1 stage of hypertension) compared to isolated exercises.
Interventions
BEHAVIORALCardiovascular fitness
A randomized single-blind controlled trial tested the hypothesis that different variants of resistance training (antagonistic lower and upper body training, agonistic lower and upper body training, and aerobic training) have different effects on blood pressure (systolic and diastolic), aortic pulse wave velocity (PWVao), and augmentation index (Aix) values and compared subjects with normotension and hypertension during and after exercise session.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Arterial stiffness - Pulse wave velocity | The training takes place twice a week, 1 training session takes 60 minutes, the total number of sessions is 5. The total length of the program is 3 weeks, duration is 5 hours. | Specifically, Aortic pulse wave velocity will be measured. The norm is up to 9 m/s, values above 9 m/s indicate impaired arterial stiffness. Arterial stiffness is a growing epidemic associated with increased risk of cardiovascular events, dementia, and death. Decreased compliance of the central vasculature alters arterial pressure and flow dynamics and impacts cardiac performance and coronary perfusion. It is measured by Arteriograph (TensioMed, Budapest, Hungary). |
| Blood pressure | The training takes place twice a week, 1 training session takes 60 minutes, the total number of sessions is 5. The total length of the program is 3 weeks, duration is 5 hours. | Measurement of changes in blood pressure level. Increase in systolic and diastolic blood pressure (mm Hg) during resistance training for agonist-antagonist and traditional agonist resistance training. Blood pressure ranges: Normal: less than 120 systolic and 80 diastolic. Elevated: 120-129 systolic and less than 80 diastolic. Stage 1 hypertension: 130-139 systolic or 80-89 diastolic. Stage 2 hypertension: at least 140 systolic or at least 90 diastolic.Investigators are looking for the safest option of resistance training for individuals with hypertension. It is measured by Arteriograph (TensioMed, Budapest, Hungary). |

It tests the cardiovascular system and reflects the general capacity of body to cope with increased physical work load and ability to recover from it. Values in steptest for untrained population: \> 90 points: excellent, 80-89 points: good, \< 65 - 79 points: average, 55 - 64 points: Poor, 65 - 79: low average. Higher values mean a better result. |
