Exercising above your target heart rate zone may (3 points)increase chance of injurydecrease lung capacityincrease hydrationdecrease perspiration

Exercising above your target heart rate zone may:

1. Increase chance of injury: When you exercise above your target heart rate zone, your body may not be able to keep up with the demand, leading to potential injuries. This could be due to overexertion or not giving your body enough time to recover.

2. Decrease lung capacity: This is not necessarily true. While exercising above your target heart rate zone can be strenuous and make you feel out of breath, it does not decrease your lung capacity. In fact, regular exercise can help improve your lung capacity over time. However, it's important to gradually increase the intensity of your workouts and not push too hard, as this can lead to shortness of breath and other health issues.

3. Increase hydration: Exercising above your target heart rate zone can cause you to sweat more, which may make you feel more thirsty. However, this doesn't necessarily mean your body is more hydrated. It's important to drink plenty of water before, during, and after exercise to stay properly hydrated.

4. Decrease perspiration: This is not true. When you exercise, especially at high intensities, your body sweats to help cool down and prevent overheating. So, exercising above your target heart rate zone would likely increase, not decrease, perspiration.
