Endurance athletes push their hearts to the limit, but tracking how much they train is tricky. Sports cardiologists know that training load, which includes factors like how often, how hard, and how long athletes train, plays a big role in how their hearts change over time. But figuring out just how much they train is a real challenge. This review looks at how scientists have tried to measure training load in sports heart studies and suggests ways to do it better.

One of the main issues is that training load has lots of parts, like how frequent, intense, and long workouts are, plus the type of exercise. This makes it hard to come up with a simple way to measure it. Researchers have used all sorts of methods, from asking athletes to fill out journals to tracking their movements with fancy gadgets. But no method is perfect, and each has its own pros and cons.

For example, keeping a training diary is easy and cheap, but athletes might not remember everything or might not be honest about how hard they pushed themselves. On the other hand, using high-tech equipment can give precise data, but it's expensive and not always practical for every athlete.

So, what's the best way to track training load? That's what this review is trying to figure out. It's like trying to find the perfect recipe for a cake – you need the right mix of ingredients and the right tools to make it just right. And just like with cake recipes, there might not be one perfect way to measure training load for every athlete.

In the end, understanding how much and how hard athletes train can help sports cardiologists better understand how their hearts respond to exercise. This can lead to better care and advice for athletes, helping them stay healthy and perform at their best.
