Exercise test variables of a population with maximal bicycle exercise test.

Area of Science:

• Cardiovascular Physiology
• Exercise Science
• Sports Medicine

Background:

• Assessing circulatory response to exercise is crucial for health and performance.
• Standardized reference values are needed for accurate interpretation of exercise test data.
• Previous research indicates potential sex-based differences in physiological responses to exercise.

Purpose of the Study:

• To establish reference values for evaluating the circulatory response to age-predicted maximal heart rate (220-age) exercise testing.
• To analyze and compare exercise response parameters between men and women.
• To provide sex- and age-specific reference data for exercise testing duration, considering body weight and height.

Main Methods:

• Analysis of exercise testing data from 942 subjects (608 men, 334 women).
• Measurement of maximal heart rate, heart rate increase per minute, systolic blood pressure, working capacity (W/kg), and exercise duration.
• Statistical comparison of parameters between male and female participants.

Main Results:

• Mean maximal heart rate was 177/min in both sexes.
• Systolic blood pressure at peak exercise was significantly higher in men (188.96 mmHg) than women (171.66 mmHg).
• Men demonstrated higher average working capacity (1.7 W/kg vs. 1.31 W/kg) and significantly longer exercise test durations (918.6 s vs. 578.4 s) compared to women.

Conclusions:

• Significant sex-based differences exist in circulatory responses, working capacity, and exercise test duration.
• Reference values for exercise testing time should account for sex, age, body weight, and height.
• The findings provide a basis for more accurate appraisal of cardiovascular function during exercise in diverse populations.
