Human-powered transport

Human-powered transport is the transport of person(s) and/or goods using human muscle power. Like animal-powered transport, human-powered transport has existed since time immemorial in the form of walking, running and swimming. Modern technology has allowed machines to enhance human-power.

Although motorization has increased speed and load capacity, many forms of human-powered transport remain popular for reasons of lower cost, leisure, physical exercise and environmentalism. Human-powered transport is sometimes the only type available, especially in underdeveloped or inaccessible regions.

In the transport sector, walking and cycling transport are often grouped together under active transport, comparing to such other transport forms as public transport, or freight transport.

Marine propulsion

Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of a motor or engine turning a propeller, or less frequently, in jet drives, an impeller. Marine engineering is the discipline concerned with the design of marine propulsion systems.

Steam engines were the first mechanical engines used in marine propulsion, but have mostly been replaced by two-stroke or four-stroke diesel engines, outboard motors, and gas turbine engines on faster ships. Nuclear reactors producing steam are used to propel warships and icebreakers, and there have been attempts to utilize them to power commercial vessels. Electric motors have been used on submarines and electric boats and have been proposed for energy-efficient propulsion. Recent development in liquefied natural gas (LNG) fueled engines are gaining recognition for their low emissions and cost advantages.

Canoeing

Canoeing is a paddle sport in which you kneel or sit facing forward in an open or closed-decked canoe, and propel yourself with a single-bladed paddle, under your own power. Kayaking is a comparable activity in a kayak which usually has a closed deck and is propelled with a double bladed paddle. In a kayak the paddler typically sits with legs extended forward.

In some situations canoeing refers to both canoeing and kayaking. Other than by the minimum competition specifications (typically length and width (beam)) and seating arrangement it is difficult to differentiate most competition canoes from the equivalent competition kayaks. The most common difference is that competition kayaks are always seated and paddled with a double-bladed paddle, and competition canoes are generally kneeled and paddled with a single-bladed paddle. Exceptions include Canoe Marathon (in both European and American competitive forms) and sprint (high kneeling position). The most traditional and early canoes did not have seats, the paddlers merely knelt on the bottom of the boat. Recreational canoes and kayaks employ seats and whitewater and surf variants employ the use of foam 'saddles' with thigh straps or increasingly foam 'bulkheads' with integrated thigh hooks that give greater boat control under extreme conditions.

Physical exercise

Physical exercise is any bodily activity that enhances or maintains physical fitness and overall health and wellness. It is performed for various reasons including strengthening muscles and the cardiovascular system, honing athletic skills, weight loss or maintenance, as well as for the purpose of enjoyment. Frequent and regular physical exercise boosts the immune system, and helps prevent the "diseases of affluence" such as heart disease, cardiovascular disease, Type 2 diabetes and obesity. It also improves mental health, helps prevent depression, helps to promote or maintain positive self-esteem, and can even augment an individual's sex appeal or body image, which is also found to be linked with higher levels of self-esteem. Childhood obesity is a growing global concern and physical exercise may help decrease some of the effects of childhood and adult obesity. Health care providers often call exercise the "miracle" or "wonder" drug—alluding to the wide variety of proven benefits that it provides.

Physical fitness

Physical fitness is a general state of health and well-being or specifically the ability to perform aspects of sports or occupations. Physical fitness is generally achieved through correct nutrition, exercise, hygiene and rest. It is a set of attributes or characteristics that people have or achieve that relates to the ability to perform physical activity.

Before the industrial revolution, fitness was the capacity to carry out the day’s activities without undue fatigue. However with automation and changes in lifestyles physical fitness is now considered a measure of the body’s ability to function efficiently and effectively in work and leisure activities, to be healthy, to resist hypokinetic diseases, and to meet emergency situations.

Team sport

A team sport includes any sport which involves players working together towards a shared objective.

A team sport is an activity in which a group of individuals, on the same team, work together to accomplish an ultimate goal which is usually to win. This can be done in a number of ways such as outscoring the opposing team. Team members set goals, make decisions, communicate, manage conflict, and solve problems in a supportive, trusting atmosphere in order to accomplish their objectives. This can be seen in sports such as hockey, football, basketball, volleyball, tennis, water polo, ultimate, lacrosse, rowing, cricket, handball and many others.

Every team sport is different. Some team sports are practiced between opposing teams, where the players interact directly and simultaneously between them to achieve an objective. The objective generally involves teammates facilitating the movement of a ball or similar item in accordance with a set of rules, in order to score points. This usually involves careful strategic planning, good preparation, and a mental and physical toughness of each individual that is part of the team. Team sports rely on all of the players working together equally in order to succeed at the task at hand. Being part of a team sport requires that each athlete has patience and perseverance since the goals put forth to accomplish might take some time to meet. This involves a good deal of dedication, hard work, and good leadership over that span of time.

Crew

A crew is a body or a class of people who work at a common activity, generally in a structured or hierarchical organization. A location in which a crew works is called a crewyard or a workyard. The word has nautical resonances: the tasks involved in operating a ship, particularly a sailing ship, providing numerous specialities within a ship's crew, often organised with a chain of command. Traditional nautical usage strongly distinguishes officers from crew, though the two groups combined form the ship's company. Members of a crew are often referred to by the title Crewman.

Crew also refers to the sport of rowing, where teams row competitively in racing shells.

Crew is used colloquially to refer to a small, tight-knit group of friends or associates engaged in criminal activity. Also used in reference to the traditional "unit" of criminals under the supervision of a caporegime in the American Mafia. However, the term is not specific to (Mafia-affiliated) organized crime. Crew can also refer simply to a group of friends, unrelated to crime or violence.
