Skipping Rope
A skipping rope (or jump rope) is a tool used in a sport involving rhythmic jumping over a rope swung underfoot and overhead. The activity, practiced both recreationally and competitively, encompasses disciplines such as freestyle routines—featuring creative techniques—and speed events focused on maximizing jumps within timed intervals. Originating from indigenous practices observed in the 16th century and later popularized in 17th-century Europe, rope skipping transitioned from a gendered pastime to a widespread sport. It flourished notably in 19th-century urbanized societies, where it became a fixture of children's culture. Governed globally by organizations such as the International Jump Rope Union (IJRU), the sport is recognized for its cardiovascular benefits, offering efficient calorie expenditure and coordination improvement. Competitive frameworks include international tournaments categorized by age, sex, and skill, showcasing techniques ranging from basic jumps ...

COVID-19 Lockdowns
During the early stages of the COVID-19 pandemic, a number of Non-pharmaceutical intervention (epidemiology), non-pharmaceutical interventions, particularly lockdowns (encompassing stay-at-home orders, curfews, quarantines, and similar societal restrictions), were COVID-19 lockdowns by country, implemented in numerous countries and territories around the world. By April 2020, about half of the world's population was under some form of lockdown, with more than 3.9 billion people in more than 90 countries or territories having been asked or ordered to stay at home by their governments. In addition to the health effects of lockdown restrictions, researchers had found the lockdowns may have reduced Impact of the COVID-19 pandemic on crime, crime and violence by armed non-state actors, such as the Islamic State, and other terrorist groups.

Aerobic Exercise
Aerobic exercise, also known as cardio, is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. "Aerobic" is defined as "relating to, involving, or requiring oxygen", and refers to the use of oxygen to meet energy demands during exercise via aerobic metabolism adequately. Aerobic exercise is performed by repeating sequences of light-to-moderate intensity activities for extended periods of time. According to the World Health Organization, over 31% of adults and 80% of adolescents fail to maintain the recommended levels of physical activity. Examples of cardiovascular or aerobic exercise are medium- to long-distance running or jogging, swimming, cycling, stair climbing and walking. For reducing the risk of health issues, 2.5 hours of moderate-intensity aerobic exercise per week is recommended. At the same time, even doing an hour and a quarter (11 minutes/day) of exercise can reduce the risk of early death, cardiovascular di ...

Exercise Intensity
Exercise intensity refers to how much energy is expended when exercise, exercising. Perceived intensity varies with each person. It has been found that intensity has an effect on what fuel the body uses and what kind of adaptations the body makes after exercise. Intensity is the amount of physical power (expressed as a percentage of the maximal oxygen consumption) that the body uses when performing an activity. For example, exercise intensity defines how hard the body has to work to walk a mile in 20 minutes. Measures of Intensity Heart Rate is typically used as a measure of exercise intensity. Heart rate can be an indicator of the challenge to the cardiovascular system that the exercise represents. The most precise measure of intensity is oxygen consumption (VO2). VO2 represents the overall metabolic challenge that an exercise imposes. There is a direct linear relationship between intensity of aerobic exercise and VO2. Our maximum intensity is a reflection of our maximal oxyge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metabolic Equivalent
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen to be roughly representative of the general population, and thereby suited to epidemiological surveys. A Compendium of Physical Activities is available online, which provides MET values for hundreds of activities. A primary use of METs is to grade activity levels for common household activities (such as cleaning) and common exercise modalities (such as running). Vigorous household chores can add up to as much energy expenditure as dedicated exercise, so it is necessary to include both, suitably ''pro rata'', in an assessment of general fitness. An earlier convention defined the MET as a multi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cycling
Cycling, also known as bicycling or biking, is the activity of riding a bicycle or other types of pedal-driven human-powered vehicles such as balance bikes, unicycles, tricycles, and quadricycles. Cycling is practised around the world for purposes including transport, recreation, exercise, and competitive sport. History Cycling became popularized in Europe and North America in the latter part and especially the last decade of the 19th century. Today, over 50 percent of the human population knows how to ride a bike. War The bicycle has been used as a method of reconnaissance as well as transporting soldiers and supplies to combat zones. In this it has taken over many of the functions of horses in warfare. In the Second Boer War, both sides used bicycles for scouting. In World War I, France, Germany, Australia and New Zealand used bicycles to move troops. In its 1937 invasion of China, Japan employed some 50,000 bicycle troops, and similar forces were instrumental in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jogging
Jogging is a form of trotting or running at a slow or leisurely pace. The main intention is to increase physical fitness with less stress on the body than from faster running but more than walking, or to maintain a steady speed for longer periods of time. Performed over long distances, it is a form of aerobic endurance training. Definition Jogging is running at a gentle pace; its definition, as compared with running, is not standard. In general, jogging speed is between . History The word ''jog'' originated in England in the mid-16th century. The etymology is unknown, but it may be related to ''shog'' or have been a new invention. In 1593, William Shakespeare wrote in ''Taming of the Shrew'', "you may be jogging whiles your boots are green". At that point, it usually meant to leave. The term ''jog'' was often used in English and North American literature to describe short quick movements, either intentional or unintentional. It is also used to describe a quick, sharp shake o ...

Cardiovascular
In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek meaning ''heart'', and Latin meaning ''vessels''). The circulatory system has two divisions, a systemic circulation or circuit, and a pulmonary circulation or circuit. Some sources use the terms ''cardiovascular system'' and ''vascular system'' interchangeably with ''circulatory system''. The network of blood vessels are the great vessels of the heart including large elastic arteries, and large veins; other arteries, smaller arterioles, capillaries that join with venules (small veins), and other veins. The circulatory system is closed in vertebrates, which means that the blood never leaves the network of blood vessels. Many invertebrates such as arthropods have an open circulatory system with a heart ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Doubletime Poster (cropped)
''Doubletime'' is a documentary film about the sport of modern-day jump roping and Double Dutch. The film follows two disparate teams—one suburban white and one inner-city black—as they train to compete against each other for the very first time. Plot In the last 30 years, jump roping has moved off the sidewalks and onto the stage. It now features astounding acrobatics, lightning speed and international competition. ''Doubletime'' follows the top two American teams: The Bouncing Bulldogs of Chapel Hill, North Carolina and The Double Dutch Forces of Columbia, South Carolina. Although they train in neighboring states, the Bulldogs and the Forces scarcely cross paths as they belong to separate leagues that do not compete against one another. The Bulldogs represent the best of gymnastic freestyle jumping found mostly in white suburbia while the Forces belong to the inner-city African American tradition of Double Dutch. For the first time, both the Bulldogs and the Forces decide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
