Cardiovascular and Cerebral Hemodynamics in Obese and Non-Obese Men

20 participants, 10 obese and 10 non-obese men, underwent physiological monitoring during step-wise incremental cycling to 60% of their age-predicted maximum heart rate. The dataset contains gas exchange, cardiac, and pre-frontal cortex hemodynamic measurements taken during rest, work, and recovery phases. It was created by Lora A. Cavuoto and published in 2020.

Use Cases

• Compare baseline heart rate and whole-body oxygen uptake per body weight between obese and non-obese cohorts.
• Analyze recovery patterns for oxygen uptake, heart-rate recovery, cardiac output, and left ventricle ejection time following submaximal work.
• Model the relationship between predicted maximal aerobic capacity and workload duration across different fitness levels.
• Investigate pre-frontal cortex hemodynamic responses during graded submaximal effort and recovery periods.

Strengths

• Data from a controlled study with 20 participants (10 obese, 10 non-obese men).
• Simultaneous measurement of gas exchange, cardiac, and cerebral hemodynamic variables during three distinct phases (rest, work, recovery).
• Specific performance metrics are recorded, such as the non-obese group reaching ~43% of predicted VO2max versus ~34% for the obese group.

Limitations

• Small sample size of 20 participants limits statistical power and generalizability of findings.
• Study population is restricted to men, introducing a gender bias.
• Specific column names, data formats, and row counts are not provided in the input.
