Introduction The present study investigated the role of training intensity in the dose–
response relationship between endurance training and cardiorespiratory fitness (CRF). The …

Introduction Unlike large population studies about cardiovascular components and how they
adapt to intensive physical activity, there is less research into the causes of enlargement of …

We investigated the effects of performance feedback (PF) on predicting maximal oxygen
uptake (V˙ O2max) using the 20m Multistage Shuttle Run Test (MST) and 20m Square …

Background: There is evidence that inspiratory muscle training (IMT) increases the athlete's
performance by decreasing the work of the respiratory muscles during exercise. IMT has …

The editors have retracted this article [1] because it contains substantial text and figure
overlap with the following articles [2–5]. The first author, Monèm Jemni, has not confirmed …

ABSTRACT WILMORE, JH, PR STANFORTH, J. GAGNON, T. RICE, S. MANDEL, AS LEON,
DC RAO, JS SKINNER, and C. BOUCHARD. Cardiac output and stroke volume changes …

The aim of the study was to evaluate and compare the maximal oxygen uptake (V˙ O2max)
achieved during incremental and decremental protocols in highly trained athletes. Nineteen …

Background The decline in maximal oxygen consumption (VO2max) with age seems to be
exacerbated in endurance-trained athletes (EA) relative to untrained healthy subjects …

Ventilatory efficiency (VE/VCO2) during exercise is defined as the ratio of minute ventilation
(VE) and carbon dioxide output (VCO2) and reflects matching of alveolar ventilation and …

Purpose To test the hypothesis that aerobic fitness is inversely related to the risk of
atherosclerotic cardiovascular disease (ACVD) in athletes with locomotor impairments …
