Which of the following is a submaximal test that can help determine the intensity of workouts?

The Rockport Walk Test is a submaximal test designed to estimate an individual's cardiovascular fitness level and help determine appropriate workout intensities. This test involves walking a mile as quickly as possible and measuring the time taken, as well as heart rate at the end of the walk. It is particularly beneficial because it allows individuals to assess their fitness without reaching maximum exertion, making it suitable for a wider range of fitness levels and minimizing the risk of overexertion.

Submaximal tests like the Rockport Walk Test provide valuable data that can be used to set appropriate intensity levels for exercise, helping individuals train effectively while still maintaining safety. This contrasts with maximal tests, which require reaching a point of exhaustion or maximum effort, which may not be suitable for everyone, especially beginners or those with certain health conditions.
