Planning in Sports (Meaning, objectives, committees & responsibilities)

(Meaning, Objectives of Planning, various Committees and Responsibilities) Plan – A blue print or preparation. A goal to be accomplished. Planning – According to Kennith H. Killen “A process of deciding in advance what is to be done and when is to be done, who is to do it, how is to be done and where is to be done”. Objectives of Planning 1.      Reduce the chances of mistakes. 2.      Increase work efficiency. 3.      Shows direction to follow. 4.        Help in better performance. 5.        Proper use of existing facilities. 6.        Better results and facilitate safety. Committees and responsibilities 1.       Prior the Competition – It includes various committees like Publicity, Purchage, Officials, Accomodation, Refreshment, Entertainment, Documentation, Medical and Transportation etc. 2.  ...

Posture and Postural Deformities (Unit 5, XII)

  Posture  A relative arrangement of body parts or segments or as accustomed position, which enables the body tofunction effectively. It is defined as position or outlook assumed by the body while standing, sitting, lying down or performing muscular activity or during stability. Good posture  is such in which trained the body to stand, walk, sit or lie so to face least strain on muscles and ligaments while moving or performing weight-bearing activities. Good posture make muscular and skeletal balance that protects the body from injuries whether running, jumping, diving, tumbling, tackling, even while sitting or sleeping etc. Two types of posture- Dynamic and Static Dynamic Posture-  How to hold yourself while moving (walking, running, for picking up). It forms the basis for movement. Muscles needs to adjust to the changing situations. Static Posture-  How to hold yourself during static position (standing, sitting, sleeping). Parts of body aligned in fixed state....

Unit-2 Children and Women in Sports

Common postural deformities  Postural deformity - it is a kind of variance in the normal   shape of the spine or body structure. Deformity - An appearance which has been spoiled or misshapen or malformed. According to Metheny, “The best posture is that in which body segments are balanced in the positions of least strain and maximum support”. The deviations from the normal postural curves mean occurrence of physical deformity in the body, it may be due to defect or damage due to several reasons which can be corrected with the help of corrective measures. Deformities of the upper extremities Kyphosis (Hump Back) It is characterized by an exaggerated rounding of the upper back (Thoracic region). It can be caused by various factors, such as poor posture, osteoporosis, or   Scheuermann's disease. Kyphosis can cause pain and discomfort, limit mobility, and affect breathing. Corrective measures for kyphosis 1. Exercise - Certain exercises can help improve postu...
