Rafaela Casandra R. Dantes. (Bachelor of Arts in Communication) Assignment in Physical Fitness 1) Definition of Physical Fitness today. Physical fitness is a general concept defined in many ways by differing scientists. Here two major categories are considered: general fitness (a state of health and well-being)‚ and specific fitness (a task-oriented definition based on the ability to perform specific aspects of sports or occupations). Physical fitness is generally achieved through correct nutrition

Flexibility Flexibility is the range of motion at a given joint. As an example‚ your shoulders should allow you to reach behind your back and touch both hands together. If this is not possible‚ you are not as flexible as you should be. This does not give you a license to force yourself to do this stretch. Flexibility must be attained in a controlled and safe manner. Flexibility is likely the most neglected aspect of physical fitness and should be a part of everybody’s weekly fitness routine

cycle describes the coordinated and rhythmic series of muscular contractions associated with the normal heart beat. The cardiac cycle can be subdivided into two major phases‚ the systolic phase and the diastolic phase. Systole occurs when the ventricles of the heart contract. Accordingly‚ systole results in the highest pressures within the systemic and pulmonary circulatory systems. Diastole is the period between ventricular contractions when the right and left ventricles relax and fill. The cardiac

Vigorous and unfamiliar exercise‚ particularly which involves eccentric muscle actions can cause muscle damage and lead to delayed-onset muscle soreness (DOMS)‚ which may impair performance. This is due to the high force features of eccentric contraction (Starbuck & Eston‚ 2011). It can also cause muscle shortening‚ swelling and loss of strength in the muscles. Injuries commonly occur during eccentric loading of the muscle; that is‚ when the muscle is contracting while it is lengthening. (LaStayo

movement. Concentric Contractions Movement happens when the muscle shortens generating force. An example of a concentric contraction is the upward motion in a bicep curl or when bringing back the lower leg before kicking a football. Eccentric Contractions Movement happens when the muscle lengthens due to a stronger opposing force. An example of eccentric contraction is the downward motion when doings pull ups or the downward motion in a squat. Isometric Contractions This is when the

was to measure‚ and compare how the cardiovascular system responds to dynamic and isometric exercise. The research question for this lab was “What is the effect of different exercise modalities on the cardiovascular system?”. In response to this research question‚ the following hypothesis was formed. During Dynamic exercise the HR‚ SV‚ Q‚ SBP would increase‚ while the TPR and DBP would decrease‚ and during isometric exercise the TPR‚ HR‚ Q‚ SBP‚ SV would increase‚ while the DBP would decrease.

Analysis of Hurdling Mechanics Brian Fuentes Lynchburg College The purpose of this paper is to analyze the motion and mechanics of hurdling during the 100 and 110m hurdles in order to better understand the proper technique to clear the barriers. When analyzing hurdling technique it’s important to consider proper body mechanics in order to understand the motion of the skill. While athletic ability is an important factor for this race‚ proper technique is more important for running
