#Intensity level trial

On a logarithmic scale, equal intervals correspond to multiplying by 10 instead of adding equal amounts. The decibel scale is a logarithmic measure of the amplitude of sound waves. Such scale is known as the “decibel scale”.The intensity level of different sounds in decibel is given in the table: Sources of sound Using equation (5), we can construct a scale for measuring the intensity level of sound. If the intensity level is measured in decibels, then equation (4) becomes: only evidence in the plethora of solar microwave burst events for a temporary decrease of emissive power from the normal S - component intensity level. It must be remembered that 1 bel is equal to 10 dB. Generally, a smaller unit called decibel is used. Therefore, using k=1 in equation (3) becomes:īel is a very large unit of the intensity level of a sound. If intensity I of any unknown sound is 10 times greater than the intensity I 0 of the faintest audible sound i.e., I=10 I 0, and the intensity level of such a sound is taken as a unit, called bel, the value of k becomes 1. The value of k depends not only on the units of I and I 0 but also on the unit of intensity level. Therefore, the intensity level of an unknown sound is given by

This difference,(L-L 0), between the loudness L of an unknown sound and the loudness L 0 is called the intensity level of the unknown sound. Subtracting equation (2) from (1), we get: Let L 0 be the loudness of the faintest audible sound of intensity I 0 and L be the loudness of an unknown sound of intensity I, then by equation (1), we can write You can measure your speed in minutes per mile using GPS watches, online mapping tools ( or measured tracks and running trails.Where k is a constant of proportionality.

#Intensity level trial

If you have run a recent time trial or a previous race (such as a 5k), you can use percentages of your race pace to assign intensity for subsequent training. Sometimes you will want to train harder and will not be able to talk so easily. Keeping your intensity manageable will allow you to accumulate more training time and will slowly strengthen your muscles, bones, and tendons (rather than breaking them down) so you are prepared for faster training later. If you cannot talk in complete sentences during your training, slow down! You can also insert planned breaks during your workout. If you are training by yourself, you can try reciting the pledge of allegiance. During most of your training, you should be able to talk with your neighbor. For example: what is the difference between a rating of an 8 and 9? How different will a rating of 9 feel from a 10? Additionally, 6-20 is a big range and often seems confusing to participants in an exercise class.Ī simplistic way to track your intensity during a workout is to use the talk test. The problem with this scale is that it is difficult for users to know and determine the difference between the numbers. It is a scale that ranges from 6-20 with 6 being very, very easy, and 20 being extremely difficult. The Borg Scale measures intensity based on perceived feelings of fatigue. Perceived exertion is based on how intense the exercise feels at any given moment. Therefore, we’re going to explore a few other methods for measuring intensity.Ģ. Borg’s Rate of Perceived Exertion (RPE)Īnother way to measure intensity is with Borg’s Rate of Perceived Exertion scale. The downside to utilizing this method to measure exercise intensity is not everyone has the money to purchase a heart rate monitor and when you are exercising on a bike, it is difficult to stop and take your pulse. It is important to remember this is just an estimate of your true heart rate maximum therefore, it is not 100% accurate. See the example below.Ī 20-year-old cyclist would want to keep a heart rate between 130-170 BPM depending on the desired level of intensity. To calculate your estimated maximum heart rate (MHR), you subtract your age from 220: (MHR=220-age). Typically, it is recommended to exercise in a range between 65%-85% of your estimated maximum heart rate (MHR). If you own a heart rate monitor, completing a few simple equations prior to coming to class will make it easy to track your intensity. The most practical and easiest way to monitor intensity is with a heart rate monitor. Anything to make an exercise more or less challenging is a matter of changing intensity. Several factors go into intensity including the weight being lifted, the amount of sets and reps performed, and the time in between sets.

Intensity is the amount of work required during exercise and the rate at which energy (ATP) is used.
