Statistics relating to sports related volleyball injuries Injuries Rotator cuff tendinitis – when serving and spiking, the rotator cuffs are worked and are very important for the shoulder to move, with over use these muscles can get irritated or fatigued. Finger injuries – during volleyball fingers are vulnerable, this injury can happen when blocking, setting, and digging. Common finger injuries include dislocations, fractures, and tendon ligament damage. Ankle sprains – most common injury in…

irritation of the nerve endings. Strains was classified by the severity of the injury the same way sprains are: Grade 1, Grade 2, Grade 3. A Grade 1 strain is a slight tear of the muscle, Grade 2 strain is a slightly larger tear of the muscle or tendon, and Grade 3 strain is the most severe, and those who have a Grade 3 strain go through a heightened amount of pain. Most strains happen to those who do sports, because they repetitively use of their muscles and tendons. Strains can be caused for a…

A contusion, more commonly known as a bruise, is a mark on the skin because of ruptured blood vessels in the dermal layer of the skin. Bruises appear in the bluish/black discoloration of the skin. Hematoma is a collection of blood found outside the blood vessels, and can be found throughout the body and may appear as a lump in the skin, while a bruise appears as a flatter mark. Also, bruise is a hematoma that is larger than 10 mm. Bruises may take 2-4 weeks to heal completely. Bruises can be…

P.E. Studies Sport: Netball Injury: Ligament tear Location: Ankle How the injury occurred: • Player is landing after receiving a catch but as they land they roll their ankle outwards Ways to prevent injury: • Wear supportive shoes designed for netball • Make sure the surface is flat and made with appropriate material • Tape or wear an ankle support • Warm-up before commencing exercise • Stop activity when any pain is felt even mild pain Steps involved in immediate assessment of injury: •…

faster speeds, which makes the product more desirable (D. Browne II, personal communication, November 3, 2016). Browne also explained track gauge which is the distance between the two rail tracks. The distance is defined as narrow gauge, standard gauge, and wide gauge. The most commonly used gauge is standard gauge which is 1,435mm (4ft 8.5in). “If the gauge isn 't within standards either too tight the trains have to work harder and if too wide it can cause trains to come off the tracks and…

A series of make shift dams and flumes are in place on the Blackstone River as it heads towards Blackstone Harbour from Crane used to control the log jams and to get the lumber up to Parry Sound. Also the river between Crane and Blackstone already had its first of several dams placed midway on its length. The Conger Lumber Co. operates throughout the area as the century headed towards its end. Other private interest companies such as Rankin Bros. subcontracting with Conger Lumber and later the…

Ergonomic Office Equipment Sitting behind a desk for long periods of time can cause stress all over the human body. A 2006 study in The American 9,279 emergency room visits for computer related injuries. A number that is up from 1,267 just twelve years earlier. (Bakalar) Other statistics show some very dramatic numbers. The average adult now spends 50-70% of the day sitting at work. 35.7% of all adults in the United States are obese. Musculoskeletal disorders account for about one-third of…

According to The Washington Post article written by Jill Adams, “People who spend two or more hours on a computer everyday are at risk for developing screen-induced eye strain, also known as computer vision syndrome.” Some symptoms associated with computer vision syndrome are eye fatigue, burning and itchy eyes, blurred vision, and sensitivity to bright light. A study conducted by the University of New York College of…

useful in finding small resistances and is used in various applications such as strain gages. The following figure shows the arrangement of a Wheatstone bridge. Figure 1: Arrangement of a Wheatstone Bridge [1] Importance of Wheatstone bridge when measuring strain: Wheatstone bridge is useful in measuring strain because it is useful in finding small resistances or small variations in resistance [2]. Whenever, a strain is applied to a particular material it changes the resistance of elements…

cyclic stress-strain responses of selected specimens having all influential parameters considered in this study, such as the volumetric ratio of transverse steel reinforcement, number of CFRP layers, and aspect ratio. In this figure, the axial stress was calculated by dividing the axial load to the column cross-sectional area, and the corresponding axial strain was derived from the average readings of the four LVDTs divided by the central gauge length of each column. The hoop rupture strain was…
