Exercise Physiologists

Today, many exercise physiology tasks still use human judgment, but smart tools are growing. For example, wearable sensors and fitness apps collect heart rate and motion in real time, and AI software can use that data to personalize workouts ^{[1] [1]}. In one study, researchers even used machine learning to predict how frail older adults respond to exercise and to help design their programs ^[2].

However, experiments show AI isn’t perfect: when a GPT-4 chatbot generated month-long exercise plans, experts found these plans were safe but too general – often focusing on caution instead of real progress ^[3]. As a result, researchers caution that AI should supplement, not replace, the expert eye of physiologists ^[3]. In clinical tests, AI shows promise: a deep-learning model boosted treadmill exercise ECG test accuracy to about 0.83 AUC ^[1] (higher than the ~0.75 AUC of older methods ^[1]).

Even so, hands-on tasks like leading a group class or giving first aid require a person’s care and empathy. Routine lab tests and emergency response still need humans.

There are reasons AI tools could spread here. Remote “tele-exercise” services boomed during COVID-19, and many people now use fitness trackers and apps ^[1]. Also, demand for exercise experts is growing – the U.S. Bureau of Labor Statistics projects a 9% increase in exercise physiologist jobs by 2034 ^[4] as the population ages.

Clinics may adopt AI to save costs or reach more clients. But adoption may be slow. Many clients and doctors trust human coaches more than apps.

Experts note that AI-generated plans lack the personal detail that people need ^{[3] [3]}. AI systems also require investment and oversight: medical programs must still be reviewed by professionals. In short, AI will likely help with data monitoring and routine advice, but the personal support and expertise of exercise physiologists remain important ^{[3] [4]}.

Humans still lead with empathy and live feedback, keeping this career relevant even as new technology arrives.
