Bio-mechanics Of Sport And Exercise

Biomechanics in sport incorporates a detailed analysis of sport movements in order to minimise the risk of injury and improve sports performance. Sport and exercise biomechanics encompasses the area of science concerned with the analysis of the mechanics of human movement.[1] It refers to the description, detailed analysis and assessment of human movement during sport activities.[2] Mechanics is a branch of physics that is concerned with the description of motion/movement and how forces create motion/movement. Therefore, sport biomechanics is the science of explaining how and why the human body moves in the way that it does. In sport and exercise, that definition is often extended to also consider the interaction between the performer, their equipment and the environment. Biomechanics is traditionally divided into the areas of kinematics and kinetics. Kinematics is the branch of mechanics that deals with the geometry of the motion of objects, including displacement, velocity, and acceleration, without taking into account the forces that produce the motion. Kinetics is the study of the relationships between the force system acting on a body and the changes it produces in body motion.[1] In terms of this, there are skeletal, muscular and neurological considerations we need to consider when describing biomechanics.[2]

According to Knudson[4] human movement performance can be enhanced in many ways. Effective movement encompasses anatomical factors, neuromuscular skills, physiological capacities, and psychological/cognitive abilities. Biomechanics is essentially the science of movement technique and tends to be most utilised in sports where technique is a dominant factor rather than physical structure or physiological capacities.[4] The following are some of the areas where biomechanics is applied, to either support the performance of athletes or solve issues in sport or exercise:

The Centre of Gravity (COG) is an imaginary point around which body weight is evenly distributed. The centre of gravity of the human body can change considerably because the segments of the body can move their masses with joint rotations. This concept is critical to understanding balance and stability and how gravity affects sport techniques.[7][9]

As mentioned above, correct biomechanics provide efficient movement and may reduce the risk of injury. In sport, it is always good to consider abnormal or faulty biomechanics as a possible cause of injury. These abnormal biomechanics can be due to anatomical or functional abnormalities.[2] Anatomical abnormalities such as leg length discrepancies cannot be changed, but the secondary effects can be addressed with, for example, a shoe insert or orthotics. An example of functional abnormalities is muscle imbalance that develops after a long period of immobilisation.[2]

The foot and ankle form a complex system which consists of 26 bones, 33 joints and more than 100 muscles, tendons and ligaments. It functions as a rigid structure for weight bearing and it can also function as a flexible structure to conform to uneven terrain. The foot and ankle provide various important functions which include supporting body weight, providing balance, shock absorption, transferring ground reaction forces, compensating for proximal malalignment, and substituting hand function in individuals with upper extremity amputation/paralysis. All these functions are key when involved with any exercise or sport involving the lower limbs.[19] The Biomechanics of Foot and Ankle Physiopedia page examines the biomechanics of the foot and ankle and its role in locomotion.

Biomechanics uses techniques including mathematical modelling, computer simulations, and measurements to enhance sport performance and reduce injury. It can be applied to a wide variety of sport and exercise activities in order to:

Biomechanical testing can take place in the lab or in the field, during training or competition. There are a wide variety of testing procedures in biomechanics depending upon the sport and also depending upon the skill within the sport. Testing methodology is determined based on the problem that needs to be answered and in consultation with the coach and athlete. Some typical biomechanical testing methods are:

Biomechanics is one of the disciplines in the field of Human Movement and Exercise Science and it can be divided into three broad categories from a research perspective. Clinical biomechanics involves research in the areas of gait, neuromuscular control, tissue mechanics, and movement evaluation during rehabilitation from either injury or disease. Occupational biomechanics typically involves research in the areas of ergonomics and human growth or morphology as they influence movement. While these two categories will briefly be discussed, the primary aim of this paper is to show the role of biomechanics in sports science and sports medicine. Research in sports biomechanics may take the form of describing movement from a performance enhancement (such as matching of impulse curves in rowing) or injury reduction perspective (such as diving in swimming or the assessment of knee joint loading during downhill walking). However, the strength of sports biomechanics research is the ability to establish an understanding of causal mechanisms for selected movements (such as the role of internal rotation of the upper arm in hitting or striking, and the influence of elastic energy and muscle pre-stretch in stretch-shorten-cycle actions). The growth of modelling and computer simulation has further enhanced the potential use of sports biomechanics research (such as quantification of knee joint ligament forces from a dynamic model and optimising gymnastics performance through simulation of in-flight movements). Biomechanics research may also play an integral role in reducing the incidence and severity of sporting injuries (such as identification of the causes of back injuries in cricket, and the causes of knee joint injuries in sport). In the following discussion no attempt will be made to reference all papers published in each of these areas because of the enormity of the task. Published and current work from the biomechanics laboratory at the Department of Human Movement and Exercise Science at The University of Western Australia will generally be used to illustrate the scope of biomechanics research within that institution.

There are also a number of studies that have tried to estimate some physiological parameters with biomechanical measures or vice versa. An example of this are the studies carried out with infrared thermography where, due to its ease of use, the aim is to estimate plantar pressure, asymmetries in the performance of forces or sports technique [11,12,13,14]. Another example is the study published in this Special Issue by Mendonça Teixeira and colleagues [15]. Due to the expensive and time-consuming characteristics of isokinetic dynamometry for screening injury risk, they analyzed the association between muscular strength imbalances and skin temperature [15]. In this case, however, they concluded that the skin temperature differences between hamstrings and quadriceps could be more related to thermoregulatory factors than strength imbalances [15].

Peter M. McGinnis, PhD,is a professor in the department of exercise science and sport studies at the State University of New York, College at Cortland, where he has taught since 1990. Before 1990, Dr. McGinnis was an assistant professor in the department of kinesiology at the University of Northern Colorado. During that time he served as a sport biomechanist in the Sports Science Division of the U.S. Olympic Committee in Colorado Springs, where he conducted applied sport biomechanics research, tested athletes, taught biomechanics courses to coaches, and developed educational materials for coaches.

One of the primary goals of this chapter is to empower the coach or personal trainer with a solid foundation in biomechanics. Another is to introduce everyone to a new way of looking at exercise in general. This new perspective is:

Again, we focus on both the movement (kinematics) and the forces that cause the movement (kinetics). The coach or personal trainer must take into account the structure of the body (specifically, the anatomy of the joints first and the body type), its intended function, and the goal of the exercise. The need to understand the ideal movement and instruct accordingly is imperative with the goal being that the trainee perform every movement as close to the ideal technique (which may be unique to them) in order to Maximize Performance and to Minimize Injury.

Sports biomechanics is a quantitative based study and analysis of professional athletes and sports activities in general. It can simply be described as the physics of sports. In this subfield of biomechanics the laws of mechanics are applied in order to gain a greater understanding of athletic performance through mathematical modeling, computer simulation and measurement.Biomechanics is the study of the structure and function of biological systems by means of the methods of mechanics (the branch of physics involving analysis of the actions of forces). Within mechanics there are two sub-fields of study: statics, which is the study of systems that are in a state of constant motion either at rest (with no motion) or moving with a constant velocity; and dynamics, which is the study of systems in motion in which acceleration is present, which may involve kinematics (the study of the motion of bodies with respect to time, displacement, velocity, and speed of movement either in a straight line or in a rotary direction) and kinetics (the study of the forces associated with motion, including forces causing motion and forces resulting from motion).[1] Sports biomechanists help people obtain optimal muscle recruitment and performance. A biomechanist also uses their knowledge to apply proper load barring techniques to preserve the body.[2] 59ce067264
