Fish oil reduces heart rate and oxygen consumption during exercise.
Dietary omega-3 polyunsaturated fatty acids (PUFAs) are readily incorporated into heart and skeletal muscle membranes where, in the heart, animal studies show they reduce O2 consumption. To test the hypothesis that omega-3 PUFAs alter O2 efficiency in humans, the effects of fish oil (FO) supplementation on O2 consumption during exercise were evaluated. Sixteen well-trained men (cyclists), rando...
متن کاملMaximal heart rate in soccer players: measured versus age-predicted.
BACKGROUND Although maximal heart rate (HR max) is widely used to assess exercise intensity in sport training, and particularly in soccer, there are limited data with regards to the use of age-based prediction equations of HR max in soccer players. The aim of this study was to compare the measured-HR max with two prediction equations (Fox-HR max = 220 - age and Tanaka-HR max = 208 - 0.7 × age) ...
متن کاملAge-predicted maximal heart rate revisited.
OBJECTIVES We sought to determine a generalized equation for predicting maximal heart rate (HRmax) in healthy adults. BACKGROUND The age-predicted HRmax equation (i.e., 220 - age) is commonly used as a basis for prescribing exercise programs, as a criterion for achieving maximal exertion and as a clinical guide during diagnostic exercise testing. Despite its importance and widespread use, the...
متن کاملBlood Oxygen Saturation and Heart Rate during Exercise a Month after a High-altitude Alpinist Expedition
Some alterations, reached during acclimatization on a high-altitude alpinist expedition, return towards pre-altitude levels at different rates during the deacclimatization phase after returning to normoxia. The aim of the study was to ascertain whether three specific adaptation characteristics – alterations in body weight (BW), arterial blood oxygen saturation (SaO2) and heart rate (HR), showed...
متن کاملValidity of heart-rate based measurements of oxygen consumption during work with light and moderate physical activity.
For ergonomic purposes it is useful to quantify the energy expenditure and the level of physical activity imposed on workers. Oxygen consumption (VO₂) is often used to calculate energy expenditure and can be used as an indication of physical activity. Twenty-five subjects participated in the study. Oxygen consumption (VO₂) in L O₂/min and heart-rate (HR) in beats per minute (bpm) were simultane...
