Clifford’s track coach once everyone on his team, to find their heart rate reserves what two pieces of information will Clifford need to know to find his heart rate reserve
To find his heart rate reserve, Clifford will need to know his maximum heart rate (MHR) and his resting heart rate (RHR).
To find his heart rate reserve, Clifford will need to know two pieces of information:
1. Resting Heart Rate (RHR): Clifford should measure his resting heart rate, which is the number of beats per minute while at rest. This can be done by placing two fingers on the wrist or neck and counting the beats for 60 seconds, or counting for 15 seconds and then multiplying by 4.
2. Maximum Heart Rate (MHR): Clifford needs to determine his maximum heart rate, which is the highest number of beats per minute his heart can reach during intense physical activity. A commonly used formula for estimating MHR is to subtract his age from 220. However, it's important to note that this estimation may not be accurate for everyone, as individual variations in fitness level and health may exist.
Once Clifford knows both his resting heart rate (RHR) and maximum heart rate (MHR), he can calculate his heart rate reserve by subtracting the resting heart rate from the maximum heart rate using the following formula:
Heart Rate Reserve (HRR) = MHR - RHR
To find his heart rate reserve, Clifford will need to know two pieces of information:
1. Resting Heart Rate: The resting heart rate is the number of times the heart beats per minute when a person is at complete rest. Clifford can measure his resting heart rate by taking his pulse in the morning before getting out of bed or after a period of calm rest. To get an accurate resting heart rate, he should measure it for three consecutive mornings and calculate the average.
2. Maximum Heart Rate: The maximum heart rate is the highest number of times the heart can beat in one minute during intense physical activity. It can be estimated using the formula: Maximum Heart Rate = 220 - Age. Clifford needs to know his age to calculate his maximum heart rate.
Once Clifford has these two pieces of information (resting heart rate and maximum heart rate), he can calculate his heart rate reserve. The heart rate reserve is the difference between the maximum heart rate and the resting heart rate. The formula to calculate it is: Heart Rate Reserve = Maximum Heart Rate - Resting Heart Rate.
By knowing his heart rate reserve, Clifford's track coach can design a training program that optimizes his cardiovascular fitness and helps improve his performance.
