Final answer:
The statement is false; resistance training can be safe and beneficial for patients with cardiac disease if it is done carefully, with low to moderate intensity, and under medical supervision.
Step-by-step explanation:
The statement that patients with cardiac disease should not perform resistance training because of the extreme effects of those activities on heart rate and blood pressure responses is False. Resistance training can be beneficial for patients with cardiac disease, but it must be done carefully and typically under medical supervision. The intensity, duration, and type of resistance exercise should be tailored to the individual's health status and abilities, focusing on low to moderate intensity to avoid undue strain on the cardiovascular system. With appropriate precautions and a well-designed program, resistance training can help in improving muscular strength and endurance, which may contribute to overall cardiovascular health and quality of life for patients with cardiac diseases.
