Abstract
Journal of Physical Fitness, Medicine & Treatment in Sports is an interdisciplinary open access peer reviewed journal that publishes original research, reviews, short communication, case reports, news, commentaries etc., in the field of sports medicine, treatment and exercise medication.
Highlights
Ventilatory efficiency is commonly assessed by the minute ventilation-carbon dioxide production slope (VE-VCO2) [13]
After overall training there was a decreasing of the VE/VCO2 slope (-6.5%) and ventilation measured at the maximum work rate in the baseline exercise testing
A “low impact” training has a lot of benefits: it reduces the onset risk of typical symptomatology, it is safer, it reduces the number of drop-outs, it is more simple to perform and it could be continued at home or monitored by qualified staff at fitness centres
Summary
Ventilatory efficiency is commonly assessed by the minute ventilation-carbon dioxide production slope (VE-VCO2) [13]. Chronic Heart Failure (CHF) is a complex syndrome characterised by ventilation inefficiency, as indicated by the increased VE/VCO2 slope, correlated with two predominant symptoms: Dyspnea and reduced aerobic performance [3,4]. Risk of mortality is thought to increased when VE/VCO2 slope values are greater than 45 when it is calculated as the last value of three during the last 30 seconds of exercise [12] or greater than 34 when it is measured over all the curve [7,11,13] or greater than 32.6 when it is measured excluding ventilatory compensation due to metabolic acidosis [2]. Chronic Heart Failure (CHF) is a complex syndrome characterised by ventilation inefficiency, as indicated by the increasing of the minute ventilation-carbon dioxide production slope (the VE/VCO2 slope), and it is correlated with two predominant symptoms: dyspnea and reduced aerobic performance. We investigated how ventilatory efficiency improves (decreasing in the VE/VCO2 slope) after a period of “low impact” supervised continuative aerobic training (SAT) and after a subsequent period of non supervised continuative aerobic “home” training (NST) in CHF patients
