BACKGROUND/AIM Iron is a vital constituent of hemoglobin, myoglobin, and some mitochondrial enzymes; therefore, body iron deficiency may result in reduced aerobic capacity. The aim of this study was to evaluate the effects of daily oral iron supplementation on body iron status, and the maximal oxygen uptake (VO2max) in female athletes with latent iron deficiency, as well as with iron-deficiency...

Maximal oxygen uptake (VO2max) indicates how many milliliters of oxygen the body can consume in a state of intense exercise per minute. VO2max plays an important role in both sport and medical sciences for different purposes, such as indicating the endurance capacity of athletes or serving as a metric in estimating the disease risk of a person. In general, the direct measurement of VO2max provi...

BACKGROUND Physical fitness and level of regular exercise are closely related to cardiovascular health. A regimen of regular intensity-controlled treadmill exercise was implemented and withdrawn to identify cellular mechanisms associated with exercise capacity and maximal oxygen uptake (VO2max). METHODS AND RESULTS Time-dependent associations between cardiomyocyte dimensions, contractile capa...

This study compares the performances obtained during soccer-specific field tests of the 20 m multistage shuttle run test (MST) and the Yo-Yo intermittent endurance test (YIET), with the measured maximal oxygen uptake (VO2max) obtained in both field tests as well as that obtained in the traditional test of running to exhaustion on a treadmill (TRT), in young trained soccer players. Twenty-one Na...

Quantification of cardiac autonomic activity and control via heart rate (HR) and heart rate variability (HRV) is known to provide prognostic information in clinical populations. Issues with regard to standardization and interpretation of HRV data make the use of the more easily accessible HR on its own as an indicator of autonomic cardiac control very appealing. The aim of this study was to inv...

INTRODUCTION Objective data on the association of maximal aerobic capacity (VO2max) with work related physical activity are sparse. Thus, it is not clear whether occupational physical activity (OPA) contributes to an increase of VO2max. This study examined the association of VO2max with work and non-work related physical activity in a Swiss working population. METHODS In this cross-sectional ...

پژوهش حاضر با هدف بررسی تأثیر تمرین استقامتی و مصرف سیر بر VO2max مردان غیر فعال انجام شد. بدین منظور، 33 مرد غیر فعال سالم با میانگین سنی (7/25±5/2 سال) به چهار گروه دارونما، مکمل، تمرین‌ دارونما و تمرین- مکمل تقسیم شدند. گروه دارونما و مکمل هر روز به مدت یک ماه 500 میلی گرم به ترتیب نشاسته و پودر سیر مصرف کردند. گروه سه و چهار علاوه بر مصرف روزانه نشاسته و سیر به مدت یک ماه سه جلسه در هفته به...

Increased heart rate variability (HRV) and high-frequency content of the terminal region of the ventricular activation of signal-averaged ECG (SAECG) have been reported in athletes. The present study investigates HRV and SAECG parameters as predictors of maximal aerobic power (VO2max) in athletes. HRV, SAECG and VO2max were determined in 18 high-performance long-distance (25 +/- 6 years; 17 mal...
