Jogging is a form of trotting orrunning at a slow or leisurely pace. The main intention is to increasephysical fitness with less stress on the body than from faster running but more thanwalking, or to maintain a steady speed for longer periods of time. Performed over long distances, it is a form ofaerobicendurance training.
Jogging isrunning at a gentlepace;[1] its definition, as compared with running, is not standard. In general, jogging speed is between 4 and 6 miles per hour (6.4 and 9.7 km/h).[2]

The wordjog originated in England in the mid-16th century.[3] The etymology is unknown, but it may be related toshog or have been a new invention.[4] In 1593,William Shakespeare wrote inTaming of the Shrew, "you may be jogging whiles your boots are green". At that point, it usually meant to leave.[5]
The termjog was often used in English and North American literature to describe short quick movements, either intentional or unintentional.[citation needed] It is also used to describe a quick, sharp shake or jar.[6]Richard Jefferies, an English naturalist, wrote of "joggers", describing them as quickly moving people who brushed others aside as they passed.[7] This usage became common throughout theBritish Empire.
In the United States, jogging was called "roadwork" when athletes in training, such as boxers, customarily ran several miles each day as part of their conditioning.[citation needed] In New Zealand during the 1960s or 1970s, the word "roadwork" was mostly supplanted by the word "jogging", promoted by coachArthur Lydiard, who is credited with popularizing jogging. The idea of jogging as an organised activity was mooted in a sports page article inThe New Zealand Herald in February 1962, which told of a group of former athletes and fitness enthusiasts who would meet once a week to run for "fitness and sociability". Since they would be jogging, the newspaper suggested that the club "may be called the Auckland Joggers' Club"—which is thought to be the first use of the noun "jogger".University of Oregon track coachBill Bowerman, after jogging with Lydiard in New Zealand in 1962, started a joggers' club inEugene in early 1963.[8] He published the bookJogging in 1966, popularizing jogging in the United States.
Jogging may also be used as a warm up or cool down for runners, preceding or following a workout or race. It is often used by serious runners as a means of active recovery duringinterval training. For example, a runner who completes a fast 400 meter repetition at a sub-5-minute mile pace (3 minute km) may drop to an 8-minute mile jogging pace (5 minute km) for a recovery lap.
Jogging is an effective way to boost endurance and improve cardiovascular health while placing less stress on the joints and circulatory system compared to more intense exercises.
According to a study byStanford University School of Medicine, jogging is effective in increasing human lifespan, and decreasing theeffects of aging,[9] with benefits for thecardiovascular system. Jogging is useful for fighting obesity and staying healthy.[10] However, individuals who areobese should exercise jogging with caution, as the risk of injury increases.[11]
The National Cancer Institute has performed studies that suggest jogging and other types of aerobic exercise can reduce the risk of lung, colon, breast and prostate cancers, among others.[12] It is suggested by the American Cancer Society that jogging for at least 30 minutes five days a week can help in cancer prevention.[13]

While jogging on atreadmill will provide health benefits such as cancer prevention, and aid in weight loss, a study published inBMC Public Health reports that jogging outdoors can have the additional benefits of increased energy and concentration. Jogging outdoors is a better way to improve energy levels and advance mood than using a treadmill.[14]
Jogging also prevents muscle and bone damage that often occurs with age, improves heart performance and blood circulation and assists in preserving a balanced weight gain.
A Danish study released in 2015 reported that "light" and "moderate" jogging were associated with reduced mortality compared to both non-jogging and "strenuous" jogging. The optimal amount per week was 1 to 2.4 hours, the optimal frequency was less than or equal to 3 times per week and the optimal speed was "slow" or "average".[15] A recent meta-analysis on running/jogging and mortality, including more than 230,000 participants found that runners were at 27% lower risk of death than non-runners, during 5.5-35 year follow-ups.[16]
