What is a possible reason for lower maximal heart rates observed in endurance-trained athletes?
Slower heart rates increase ventricular filling time
What is slowest heart rate animal live in earth?
In general, the larger the animal is, the slower is its resting heart rate. Great whales (the largest animals) have resting heart rates around 7 beats per minute (bpm), according to Gordon Ramel who also notes that some smaller animals have even lower heart rates while hibernating (for example, the European hedgehog, which slows from 200-280 bpm while active to around 5 bpm while hibernating). (It's a good bet that there is some other animal with an even slower hibernating heart rate -- like the frogs and toads that may hibernate for 17 years at a time). Cold-blooded animals slow their hearts dramatically at low temperatures. Crocodiles, for example, slow their hearts from 24-40 bpm in daytime (28C) to 15-20 bpm at night (18C), and to as slow as 1 bpm at 10C
What is a slow moving animal?
No, it is not true that slower moving animals have slower metabolic rates. Infact , animals with small bodies have higher metabolic rate.
How are the respiration rates of fish related to their heart rates?
i think its the heart beat
Does eating candy change heart rates?
does eating candy change heart rates yea it dose
How do rates of cooling differ for New York and Bismark?
heating-Quicker in ny and slower in bismarck. cooling-slower in ny and quicker in bismarck.
What are Diversification Rates?
Different diversification rates for two clades of animals.
Where can I get more advice on low heart rates?
Bradycardia, or low heart rate is not a cause of concern unless you are experiencing symptoms. Athletes very commonly have extremely low heart rates (even as low as 40 beats per minute!) without consequence due to their endurance training. If your low heart rate is causing you to pass out or feel sick, this could be a problem with the SA node, or pacemaker in your heart. Whenever the natural pacemaker in your heart is sick, other slower pacemakers take over to keep the heart beating. It is possible that you may be in need of a pacemaker. You should discuss this with your doctor.
What conclusion can you write about heart rates?
no
Which animal has the fastest heart beat?
In general, the larger the animal is, the slower is its resting heart rate. Great whales (the largest animals) have resting heart rates around 7 beats per minute (bpm), according to Gordon Ramel (http://www.earthlife.net/mammals/blood.html), who also notes that some smaller animals have even lower heart rates while hibernating (for example, the European hedgehog, which slows from 200-280 bpm while active to around 5 bpm while hibernating). (It's a good bet that there is some other animal with an even slower hibernating heart rate -- you might want to research this question a bit more). Cold-blooded animals slow their hearts dramatically at low temperatures. At http://www.peteducation.com/article.cfm?cls=17&cat=1848&articleid=295 you can read about how crocodiles, for example, slow their hearts from 24-40 bpm in daytime (28C) to 15-20 bpm at night (18C), and to as slow as 1 bpm at 10C (which is pretty cold for a croc). At the other extreme, shrews have an average heart rate of 800 bpm and a peak rate over 1300 bpm. George Moody Harvard-MIT Division of Health Sciences and Technology
Baby's Pulse rate?
why are babies heart rates faster than an average grown ups? why are babies heart rates faster than an average grown ups? why are babies heart rates faster than an average grown ups?
What evolution do sloths have?
No fast predators that sloth camo. can't fool so sloths which are slower with slower metabolic rates are better off. This is why sloths are so slow.
