Background
What is the foremost cause of mortality worldwide?
Cardiovascular disease
What was the final sample size of the study?
30 participants
What was the age-range of participants in the study?
18-30 years old
What was the main finding of the paper?
Normotensive subjects’ higher SBP presented delayed recovery following moderate exercise compared to individuals with lower SBP by examining HR and HRV.
What systolic and diastolic blood pressures are considered pre-hypertensive?
DBP: 129-139 mmHg
SBP: 80-29 mmHg
True or False? Females and males were both study participants.
False
What was something that was controlled for in the study? (multiple correct answers)
Circadian Influences, Room Temperature, Humidity, Drinking Behaviors, Diet, Clothing
Was any statistical differences detected for blood pressure and RR?
No
A previous study found that slower autonomic recovery after exercise has been linked to...
Higher cardiovascular risk
People who had a higher resting SBP of ____ and a BMI over ____ were excluded from the study.
120 mmHg
25 kg/m2
What is a sphygmomanometer used for
To measure blood pressure
What was a limitation to the study mentioned by the authors?
The sample size was very small sample so they need to reproduce findings in larger samples. The study evaluated only young, healthy men with the same physical status so the data cannot be extrapolated to different ages or genders
What noninvasive method is used to measure autonomic modulation?
Heart rate variability
How did Group 1 differ from Group 2 in the study?
G1: SBP< 110 mmHg
G2: SBP between 110 and 120 mmHg
BOMB
-400 points
In terms of heart rate recovery, a statistically significant difference was observed up to which minutes of rest for G1 and for G2 compared to resting heart rate?
G1: up to the 20th minute
G2: up to the 60th minute
What was the researcher's question of this study?
Would normotensive subjects with higher SBP (110-120 mmHg) present slower cardiorespiratory and autonomic recovery following submaximal aerobic exercise compared to normotensive individuals with lower SBP (<110 mmHg)?
Name three criteria that excluded subjects from the study?
Smoking, Overweightness, Sedentary Lifestyle
Bonferroni post test or ancova with BMI correction
In terms of autonomic recovery, at what time point after exercising did G1 show no statistical difference to resting Heart Rate Variability when compared to G2.
G1 at 50 minutes, G2 at 60 minutes
