Last Name 2IntroductionStrength and power are components of fitness which have many similarities. These similarities include the need to use force to conquer resistance while in motion. Contraction of specific muscle is involved in both and are components of fitness which can be measured. It is the ability of the muscle to overcome resistance through energy application in one effort while the quantity of work done per unit of time is power. Strength tests comprise the squat for the lower body, lifting weights upwards when in a supine position (meant for upper body) and liftingfrom a standing position for both the lower back and leg assessments(Benedek & Leuciuc, 2010).Power is skill related element while strength is measured by the amount of weight lifted.Factors Influencing Strength PerformanceAge Increase in the size of muscles and strength can happen to everyone regardless of age after undergoing a strength training program which is effective and safe (Brandon, 2005). However, strength plus muscle gain happens to be high from 10 and 20 years since those are the fast growth and development years. When one gains the standard physical maturity developments of muscles is not fast as compared to the teenage years.
Last Name 3A Graph showing relationship between age and muscle strengthGenderGender is the state of being a male or a female. The quality of our muscle is not affected by age, unlike quantity. Male and female muscles are similarly characterized. The male sex hormone increases the muscle size hence making men have more muscle tissues than women (Casartelli, Muller, & Maffiuletti, 2010). The size of the muscle is directly proportional to the strength, therefore, the bigger the muscles one has, the stronger he is, and this is why most males are muscular and stronger than females.
Last Name 4Limb and muscle lengthLimb length is a naturally determined strength factor. People with short legs lift lots of weight due to advantageous leverage aspects than to people with long legs whose leverage factors are not beneficial (Cornie et al., 2007). Differences in the development of strength may rise due to the length variation of muscles. People with long muscle have tremendous possibilities for size and strength development compared to people with short muscles.Point of tendon insertionTendons similarly known as sinews are tight bands of fibrous connective tissue that joins muscles to bones and are capable of enduring pressure. They are made of collagen. The function of tendons is to transmit forces (Dotan & Bar –Or, 2003). The point of tendon insertion influences the strength of muscles. A good example of this can be given by assuming Jude and Jade have same arm as well as muscle lengths. Jude’s biceps tendons attach to her forearm while Jade's biceps attaches to his elbow joint. Here Jude has a biomechanical benefit of lifting more weight than Jade.Type of muscle fiber Muscle fiber is of two kinds namely, fast twitch and slow twitch. Fast twitch is used for anaerobic activities while slow twitch is used for aerobic exercises (Fahey et al., 2005). Slow twitch yields small levels of force for a long period making them more suitable for endurance activities. Fast twitch yield high levels of energy for a short period and therefore are the best ideal for power activities, e.g., weightlifting.
