“…However, these pilot data are needed before the method can be safely applied to cardiac patients. Relative to no-KAATSU, exercise intensity at VT in KAATSU was ~13% lower in a previous study [30] and ~33% lower current study. These data suggest that KAATSU substantially reduces the mechanical load needed to reach VT.…”

Low-intensity endurance exercise with blood flow restriction (KAATSU) is under consideration for use in cardiac rehabilitation. However, the physiological responses to such exercise have not yet been fully characterized. In an initial effort in healthy males (n = 11, age: 26.3±4.6 y), we compared the physiological responses to low-intensity endurance exercise with and without a thigh KAATSU. Participants performed maximal graded exercise testing using a cycle ergometer with or without KAATSU. We examined responses to cycling exercise at ventilatory threshold (VT) in heart rate (HR), oxygen consumption (VO2), dyspnea, ratings of perceived exertion (RPE), blood pressure (BP), and rectus femoris activation. Participants reached VT at a lower mechanical load, HR, VO2, dyspnea, and double product (HR×systolic BP) with KAATSU vs. no-KAATSU. At VT, RPE, and rectus femoris activity did not differ between the two conditions. These results suggest that KAATSU reduced exercise intensity to reach VT and the physiological responses to exercise at VT without changes in knee extensor muscle activation. Results from this pilot study in healthy males suggest that KAATSU aerobic exercise at VT intensity has the potential to be an effective and low-burden adjuvant to cycling in cardiac rehabilitation.

“…Exercise spirometry is a new technology for assessing physical fitness that uses cardiac electrocardiography (CPET) to measure exercise capacity and assess the risk of heart problems [1]. CPET is a non-invasive technique that measures a person's body's response to physical activity by measuring oxygen consumption and carbon dioxide production during exercise [2,3].…”

Ergospirometry is a modern approach to the diagnosis of physical health that involves the use of exercise testing to measure cardiopulmonary function. Aims: To compare the distribution of health characteristics and their relationship between participants, to evaluate the accuracy of hypertension, hyperlipidemia and diabetes in both groups, to measure respiratory rate and heart rate between ergospirometric testing and traditional testing for physical health assessment. Study design: A comparative cross-sectional design to assess ergospirometric testing and traditional testing for physical health assessment. Methodology: The study employed a comparative cross-sectional design, utilizing convenience sampling to recruit participants for ergospirometric testing on a treadmill and the traditional 6-Minute Walk Test. Sample size determination yielded 100 participants (50 per group). Data on sociodemographic, comorbidities, and physiological parameters were collected and analyzed using descriptive statistics, chi-square tests, and independent sample t-tests. Results: The study compared Ergometric testing on a treadmill with the Traditional 6-Minute Walk Test across various parameters. Participants undergoing Ergometric testing were younger with more females and smokers, while the Walk Test group had higher BMI and exercise rates. Ergometric testing revealed higher rates of hypertension (P = 0.034) and hyperlipidemia (P = 0.021) but lower diabetes prevalence (P = 0.016). Additionally, Ergometric testing showed a better detection of respiratory parameters, exercise stress detection (P = 0.009), and cardiovascular parameters as compared to Traditional testing. Furthermore, it has a higher sensitivity 85% and specificity 80% compared to the traditional testing having sensitivity 75%, and specificity 70%. Scientific Novelty: Spirometry testing has made an impact on physical examination today; using advanced technology to achieve the best, sensitivity and specificity marks changes in the actual examination. Conclusion: Ergometric testing (treadmill) shows a significant advantage over traditional testing (6-Minute Walk Test) in diagnosing physical health conditions with a high sensitivity, specificity, and comprehensive parameter assessment.
