 | Treadmills | Origins
Treadmills were historically used as a method of reforming offenders in prison, an innovation introduced by Sir William Cubitt in 1817; these were also termed treadwheels. The first private health club in the U.S. was started by Professor Louis Attila in 1894. Cardio workout machines entered the clubs much later and were developed initially for the hospital. The first medical treadmill designed to diagnose heart and lung disease was invented by Dr. Robert Bruce and Wayne Quinton at the University of Washington in 1952. Dr. Kenneth Cooper's research on the benefits of aerobic exercise, published in 1968, provided a medical argument to support the commercial development of the home treadmill and exercise bike.
Advantages
As a cardiovascular exercise:* Running or walking on a treadmill can be an effective way to work out, like other complex cardiovascular exercises (similar to non-treadmill walking/running). As with all exercise, regular treadmill use increases endurance.* Treadmills offer the benefit of reduced impact since all treadmills offer some sort of shock absorption. Exercising on a treadmill can reduce the strain to the ankles, knees and lower back of users.
As an indoor activity:* Users who would not run/walk outdoors (e.g. due to unfavourable weather conditions, uneven road surfaces, dangerous neighbourhoods or unwanted attention) may use an indoor treadmill.* Users who do not wish to join a gym may use an indoor treadmill at home.* Users can do other things while exercising, such as watching television or reading.
As a machine:* Enables exact calculation and adjustment of slope and speed.* As most of the factors of the activity are known, the energy expended may be calculated.* Some treadmills have special features such as step count, heart rate monitors, amount of calories expended.
Disadvantages
* Many users find treadmills boring and lose interest after a period.* Cost of purchase and electricity to run the treadmill is significantly greater than running outside.* Takes up space in homes (disadvantage reduced by "folding treadmill" option).* May cause personal injury if not used properly.* Can make a loud grinding noise if the belt keeps slipping.* Lack of wind resistance makes running on a treadmill easier than it would otherwise be on an equal elevation grade outdoors. Training for outdoor races is complicated due to the subtle differences.* There is little need to propel yourself on a treadmill, making running easier and therefore not giving you an accurate representation of running on the ground. This can be a disadvantage when training for outdoor races.* Ordinary treadmills, even the expensive models at gyms and clubs, are not usually able to tilt at the steep slopes used on medical treadmills for standardized stress tests.* Imposes a strict pace on runners, giving an unnatural feel to running which can cause a runner to lose balance.* As with all forms of cardiovascular exercise, the risk of cardiac arrest is significantly increased. Treadmills may further this risk, as indoor comforts, such as air conditioning, may cause a user to feel more comfortable and less likely to stop due to exhaustion.
Other uses
As it is basically a conveyor belt, the treadmill can be used for activities other than running. If horses are being tested (especially in jockey racing) they will be put on a specially constructed treadmill. Large treadmills can also accommodate cars.
Omnidirectional treadmill
Omnidirectional treadmill
Advanced applications are so called omnidirectional treadmills. They are designed to move in two dimensions and are intended as the base for a "holodeck". There are several solutions which were proposed and research continues because some issues remain unsolved until now such as large size, noise and vibration. | |

 | Corolla 2002 at Harrisburg Car Show | The Corolla seats five occupants on cloth-upholstered seats. Compared to some rivals, the Corolla’s standard-equipment list is on the meager side. Even on the top-of-the-line LE, such items as air conditioning and power windows, locks and mirrors are optional rather than standard. In fact, the LE is the only Corolla model that comes with a standard cassette player, as well as a split-folding rear seat, rear-window defogger and tilt steering wheel. None of this seems to deter buyers, who simply check off desired items that are offered in special packages. | |

 | Philippine Jeepneys | Jeepneys are the most common form of public transport throughout the many islands of the Philippines. In Manila they are so numerous, that there is almost constantly traffic congestion. The jeepneys don't have air-conditioning. They have open windows. Most of the time the jeepneys are constantly-packed with many passengers. Jeepneys offer one of the cheapest ways of getting somewhere. | |
