BACKGROUND Prevention of cardiac events during competitive sports is fundamental. New technologies with remote monitoring systems integrated into clothing could facilitate the screening of heart disease. Our aim was to evaluate the feasibility of Nuubo system during a field stress test performed by soccer players, comparing results with treadmill ergospirometry as test reference. METHODS Nine...

INTRODUCTION AND OBJECTIVES Angiotensin-converting enzyme (ACE) is associated with the development of cardiac hypertrophy and improved physical fitness. The objective of this study was to investigate the relationship between the ACE gene insertion/deletion (I/D) polymorphism and adaptation to sports training. METHODS The study included 299 elite Spanish athletes (193 men and 106 women) from 3...

BACKGROUND The aim of this study was to analyze the influence of active and passive smoking on cardiorespiratory responses in asymptomatic adults during a sub-maximal-exertion incremental test. METHODS The participants (n = 43) were divided into three different groups: active smokers (n = 14; aged 36.5 ± 8 years), passive smokers (n = 14; aged 34.6 ± 11.9 years) and non-smokers (n = 15; aged ...

The aim of this investigation was to determine the effect of exercise training on the levels of plasma cytokines and acute phase reactants in the early post acute myocardial infarction (AMI) period. Sixty patients were enrolled into this three-week cardiac rehabilitation study. The mean time from AMI was 7.08 +/- 1.60 days, and the patient mean age was 60 +/- 10 years. Subjects were randomly as...

Evaluation of aerobic fitness indicators in canoers reveals functional characteristics acquired through specific training, which can be related to competitive performance. Thus, the aim of the present study was to evaluate functional evaluators obtained in ergospirometry test of young canoers, as well as to verify the relationship of these variables with performance in 200, 500 and 1000 m dista...

In this study, we examined whether glycemic status influences aerobic function in women with type 1 diabetes and whether aerobic function is reduced relative to healthy women. To this end, we compared several factors determining aerobic function of 29 young sedentary asymptomatic women (CON) with 9 women of similar age and activity level with type 1 diabetes [DIA, HbA1c range = 6.9-8.2%]. Calf ...

During stay on board, seafarers have limited influence on quality and quantity of food over several months. Furthermore, the nutrition on board is characterised by different dietary habits in the multi-ethnic crews, differential food supply in crew's and officers' mess room and irregular mealtimes due to the shifts on board. Internationally, nutritional situation on board is not standardised, b...

BACKGROUND Portable respiratory inductive plethysmography (RIP) systems have been validated for ventilatory assessment during resting conditions and during incremental treadmill exercise. However, in clinical settings and during field-based exercise, intensity is usually constant and submaximal. A demonstration of the ability of RIP to detect respiratory measurements accurately during constant ...

BACKGROUND Helium/oxygen therapies have been studied as a means to reduce the symptoms of obstructive lung diseases with inconclusive results in clinical trials. To better understand this variability in results, an exploratory physiological study was performed comparing the effects of helium/oxygen mixture (78%/22%) to that of medical air. METHODS The gas mixtures were administered to healthy...

The purposes of this study were to determine the relationship between performance in the Yo-Yo intermittent recovery test level 1 (YIRT1), the Yo-Yo intermittent recovery test level 2 (YIRT2) and the Yo-Yo endurance test (continuous) (YET) with maximal oxygen uptake (VO2max) and Wingate anaerobic performance (WaNT) test results in young soccer players (age 15.00 ± 0.0 years, body height 176.3 ±...
