Sort of yeah. Your cardiovascular system provides oxygen to your brain, which, it needs to function properly. A weak cardiovascular system provides less oxygnated blood and has to work harder than a stronger healthier one to get the same amount of oxygen to the brain. When your brain is deprived of oxygen, your thinking quality decreases.
