Motion Capture cameras are retro-reflective cameras used to help capture body motions in order to study the movements in space, also known as kinematics. Motion capture cameras can capture at 1 million millisecond intervals, making frames as high as 1,000 per second. There are two types of motion capturing cameras, 2-D and 3-D. Two-dimensional motion capture occurs when only using one motion capture camera. 2-D only incorporates the X an Y coordinates. When using more than one camera the Z coordinate is incorporated, making it a three-dimensional motion capture. Motion capture can be fairly cost effective when using only one camera and a computer to digitize the film into sequences of different frames. Then one can compare the videos and frames with other videos to help discover and form ideas to improve and further the knowledge on motion in space.
Three dimensional motion capture requires more than one camera to create depth in the motion being performed. A good example is eyesight. If someone where unfortunate enough to only have one eye they would be unable to see the 3-D depth in motion. Having two eyes allows for depth in motion when seeing, which is similar to the idea of using two cameras in order to fully capture the depth in motion. One of the few techniques discovered and used in 3-D motion capture is Direct Linear Transform (DLT). Using the idea that, images from the cameras are determined by their placement to discover their distances, equations could be formed and used. Test subjects wear reflective markers to allow the cameras to follow their movement and motion through space. These reflective markers are placed on certain joins and parts of the body the researcher would like to study. The reflective markers ca...

...gg, 2013). If motion capture could be used to further this research it could be a huge advancement in understanding what actually creates the most accurate and powerful shot.
If motion capture is able to help produce the most accurate and powerful shot, after analyzing and collecting data from multiple lacrosse athletes, it could potentially improve the game. Some athletes could attend a sports program to produce the “perfect” shot. They would be taught how to exactly position their arm muscles, torso and joints to follow through with the swing of the stick creating the best motion of the ball. This study could potentially be a huge advancement in the game of lacrosse, furthering the popularity of the game. It could help advance the overall background of neuromechanics to the game. Furthering the research on motor control and biomechanics in the game of lacrosse.

    While over the spring break my father, boyfriend, and I partook in supporting our home towns local ice hockey team the San Antonio Rampage take on Grand Rapids Griffins. However, while going through the procedure of finding our seats, attaining snacks and beverages, and watching the game I was able to examine different kinesiology components throughout the event. Just by entering the AT&T center one can be overwhelmed by the lights and excitement of everything going on however, the organization going on here is very extensive and if broken down they can analyze how everything can relate to sports kinesiology in some way.

  • Biomechanics In Ice Hockey

    1870 Words  | 4 Pages

    Biomechanics allows the study of ice hockey to occur. In terms of ice hockey, biomechanics can be used to study a players shot, a goaltenders movement, line changes where players jump over the boards to get on and off the ice, and impacts. Multiple options are available in regards to recording biomechanical values during ice hockey play. These options often include instruments with the player’s helmet, which do not disrupt the player’s movement. Other options being used are accelerometers attached to the players extremities. Currently studies in ice hockey are looking at head impacts and the injuries connected to those impacts. These impacts are often categorized between event type, impact location, and impact object. These categories are helpful in determining what happened to cause the impact, once the impact is determined biomechanics is used to determine liner and rotational accelerations. The values that are calculated for the linear and rotational accelerations can be used to determine if head injury is likely for similar events or if a head injury occurred during the event

    Broer was the first to call attention to the similarity of movement patterns used in seemingly dissimilar activities such as the baseball pitch, the badminton clear, and the tennis serve. Objective evidence of such similarities between throwing and striking activities within each of the three major upper-extremity patterns; overarm, sidearm and underarm. The representative activities from these categories across throwing patterns also showed great similarity in the muscular action of the lower extremity. Atwater distinguished between the overarm and sidearm throwing patterns in terms of the direction in which the trunk laterally flexed. When lateral flexion occurred away from the throwing arm, and overarm pattern was used; lateral flexion toward the throwing arm indicated a sidearm pattern. The underarm patter is distinguished by motion predominantly in a sagittal plane with the hand below the waist. Each pattern involves a preparatory movement referred to as a backswing, or windup, followed by the establishment of a base of support prior to the initiation of the force phase and ending in the follow-through. The base of support in the direction of the force application; forward and backward is a distinguishing feature of skill level. It has been well documented that more highly skilled individuals have longer strides. Once the base has been established, the more proximal segments begin the force application phase while the more distal segments complete the backswing.

    Franklin County was one that was affected by a officer involved shooting. The Franklin County was under a lot of heat due to the fact that the videos that were released didn’t benefit the officers. Additionally, the videos that were recorded in Pasco only show one side of the story. We don’t know what the officers saw in the moments leading up to the shooting. However, if the officers were wearing body cameras, people would probably understand why those actions were taken. Franklin County should implement body cameras for their officers so that next time there’s a situation like this the police officers and the community will be protected.

  • The Camera Obscura And Its Impact On Society

    767 Words  | 2 Pages

    For my Research paper, I have studied how the ‘Camera Obscura’ was created and its impact on society. The reason I have chosen to discuss this topic is because it baffles me that an image can be created without using man made technology. An image could be simply made by a small crack in a cave, projecting an image of the outside, inside. The first use of light to create an image is the camera obscura. The name, ‘camera obscura’, was created by Johannes Kepler a German astronomer, in the early 17th century. He made it using a tent to observe the solar eclipse. The word ‘camera obscura’ means ‘dark chamber’.

    Correctional officers spend a great amount of time with inmates behind prison walls, and work in close proximity with them as well. Correctional officers work in shifts and sometimes they pull a double to make some overtime money. Long hours spent in jail or prison facilities will create opportunities for some officers to make advances towards an inmate. Pollock (2014) states, “This familiarity with inmates sometimes tempts officers to engage in unethical behaviors such as sexual relationships (p. 194). It is up to correctional administrators to set the tone and exemplify good leadership and management skills that can instill good working ethics in the minds of young correction officers. Clear et al. (2013) believed in an innovative screening

  • The Physical Fitness Of Basketball

    1831 Words  | 4 Pages

    Basketball is a "transition game. Players continuously switch between defensive and offensive plays throughout the game. The plays include strenuous physical, such as running/sprinting, cutting, feints, jumps, and landings. Rapid turns and proximity during one-on-one situations increase the possibility of physical contact. Thus, frequent intermittent running and sprinting characterize the action of the game. Motion analysis has shown that depending on individual playing-time; basketball players cover a distance between 4.6 and 5.8 km per game, with mean heart rates between 80 and 90% of individual maximum heart rates (European Network for Sports injuries prevention, 2008). Consequently, players need to rid of highly advanced basic...

  • Film: A Dying Art or an Evolving Franchise?

    1459 Words  | 3 Pages

    Filmmaking, the art of the motion picture, is a comparatively new art form that combines a moving image in conjunction with sound, primarily to tell a story. Due to the medium of capturing the image is evolving, so is the art in its entirety. Modern technology is allowing a more cheaper, streamlined form of production, thus rendering older methods unnecessary. Celluloid filmmaking is the old method of capturing film on a negative film strip and developing it later in its most natural state, whereas digital film is capturing synthetic and manipulatable pixels on a computer-like device. Digital filmmaking should be a primary film medium but not completely eradicate the dying celluloid film culture.

  • The Physics of Basketball

    1941 Words  | 4 Pages

    The most important part of the game of basketball is shooting the basketball, after all the object of the game is to put the basketball through the basket. A shot is taken by a player pushing on the ball and launching it toward the basket and upon the ball hitting the rim or backboard physics refers to this action as a contact force. Using this concept of contact force a shot can be calculated exactly. From a player’s height, the mass of the ball and a given position on the court which would include the distance from the basket it is possible to calculate the exact angle and force the shooter must apply to make a basket every time he or she shoots the ball. Of course if it were this easy basketball would not be as fun to watch or play. The problem with hitting a shot every time with the calculated angle and force is that the ball would have to travel toward the basket with the exact angle and force calculated for that particular shot. What makes this difficult is that the muscles in our body would have to be controlled flawlessly to push the ball with the exact amount of force and to give the ball the exact angle that is needed every time a shot is taken...
