The second was historically defined as 1/86400 of a day in 1832, which was based on the definition of a day as the approximate amount of time required for the Earth to complete a full rotation cycle relative to the sun. You can use this calculator to find your ideal pace to run an event like a marathon or half marathon. game1.swfWhen the test starts, it will present you with a choice of lesson and time.

The second factor we examine is Similarly to heart rate, the most accurate way to determine these thresholds is through testing within a lab setting. However, both aerobic and anaerobic thresholds can also be estimated using a number of different methods, some of which involve the use of a heart rate monitor. According to a 2005 study, the most accurate way to determine anaerobic threshold (outside of blood work in a lab) is a 30-minute time trial in which heart rate is monitored. In this time trial, a person must run at maximum effort, averaging their heart rate over the last 20 minutes of the run. The average heart rate over the last 20 minutes is an estimation of the person's anaerobic threshold heart rate, also known as lactate threshold heart rate (LTHR). It is important that the time trial be performed alone. If it is done in a group setting, the duration must be increased to 60 minutes rather than 30 minutes. Aerobic threshold heart rate can be estimated by subtracting 30 beats per minute from the anaerobic threshold heart rate. Maximum heart rate (MHR) is most accurately measured using a cardiac stress test, which involves measuring a person's heart function (including heart rate) at periodically increasing levels of exercise. These tests typically range from ten to twenty minutes in duration, which can be inconvenient. As such, there are many estimates for MHR based on age, which is strongly correlated with heart rate, though there is little consensus regarding which formula should be used. The most commonly cited formula for calculating MHR is:Understanding aerobic exercise is particularly important when training for a long-distance activity such as a marathon. Determining a pace that can be maintained while using energy primarily derived through aerobic means, referred to as an "aerobic threshold pace," helps maintain a balance between fat and carbohydrate utilization. This pace requires a relatively low level of intensity, and is usually maintainable for a few hours. Increasing aerobic threshold pace allows for a faster sustainable pace and is a large aspect of many marathon training programs. Current use: The minute, as a multiple of the second, is used for all manner of measurements of duration, from timing races, measuring cooking or baking times, number of heart beats per minute, to any number of other applications. Second Taking into account our information, table and calculator, you definitively know how long 1.5 min in hr is. Find your running pace per mile, kilometer, yard or meter. Calculate the distance you can run in a given amount of time, time required to run a specific distance, or your running speed. Use this calculator to find average pace for running, biking, swimming or walking. How to calculate running pace In 1967, the second was defined exactly as "9,192,631,770 times the period of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom." This definition has since been updated as of late 2018 to be more rigorously defined, but otherwise, is effectively the same. This new rigor does not affect how the second is used in everyday life.

The minute is a unit of time or of angle. As a unit of time, the minute is equal to 1/60 of an hour, or 60 seconds. In the UTC time standard, a minute on rare occasions has ..more definition+ Next, we show you how to change the amount of time to hours and minutes combined. 1.5 Minutes to Hours and Minutes 1.5 minutes = 0 hours and 1.5 minutes. Example Calculation 2: How long will it take me to run a half marathon if my average pace is 10 minutes, 30 seconds per mile? Current use: As the SI base unit of time, the second and its multiples are ubiquitous. There are few, if any, modern applications in which time is measured in a form other than the second and its multiples.New lessons 38 through 40 include Spanish, French and German words. Lessons 36 and 37 are commonly misspelled words. lessons are available, so if you want to see your words-per-minute is on the home row keys, or your speed in the 10-key you History/origin: Unlike many units that have had numerous definitions throughout history, the second has only had four different definitions.
