Quadriceps femoris muscle

neural input to the CNS from mechanoreceptors in the joint capsule, ligaments, muscles, tendons and skin” (Beard et al 1993). There is loss of both stability and proprioception in the knee following an injury to the anterior cruciate ligament (ACL) (Barrett DS 1991). The afferent nerves are responsible for proprioception arise from the ligaments, capsules surrounding muscles and skin (Grigg P et al 1982) activating muscle contraction, which may be assumed to help stabilise the joint (Schultz RA…

The main muscle used in the vertical is the quadricep femoris. The quad has four main parts; rectus femoris, vastus medialis, vastus lateralis, and the hip bone(Llamas 16-17). The quad helps to straighten the leg at the knee(Conway). The quad is the most powerful muscle used in a vertical jump. The vertical also uses hamstrings, hip flexors, and calves. Certain exercises can make these muscles stronger for one’s vertical. Next, a vertical jump can also…

Dogs to Humans Humans and dogs are similar in many different ways, one way is that they have similar muscular systems. We humans have some similar muscles as dogs like, gluteal muscle, biceps, latissimus dorsi, trapezius, deltoid, and the external oblique. The different muscles are used by dogs and humans in pretty much the same sense so they can run, walk, and jump. The dog’s muscular system is one of the biggest systems in their body. There are two important functions of the muscular system…

trying to figure out whether a 20-30 minute moderate intensity warm up is enough to reach someone’s optimal sprint performance. Many studies have found that the most influential factors that warm-ups have on sprint performance include the increase of muscle temperature (Faulkner, Ferguson, Hodder, & Havenith, 2013 & Zois, Bishop, Ball, & Aughey, 2011 & Sander, Keiner, Schlumberger, Wirth, & Schmidtbleicher, 2013 & Mohr, Krustrup, Nybo, Nielsen, & Bangsbo, 2003). This leads to the second part of…

Movement analysis is a major key in sports as it dissects the certain movement of muscles and joints to perform a certain action in the sport. A basketball jump shot uses all of the movement phases, from the stance phase, preparatory phase, movement phase, follow-through phase and recovery phase. The jump shot has gradually evolved in the NBA, and is considered one of the most important and most commonly used shot in basketball. There are many sharpshooters in the NBA, like Kevin Durant, Stephen…

2007). There is an innumerable amount of physiological benefits of exercise such as to combat health conditions and diseases. Regular physical activity can improve muscle strength and boost endurance during day life tasks. Exercise can also help to prevent weight gain, promote the loss of weight and supports in other to gain muscle fitness among a wide variety of other benefits. A lot of research have been done of these physiological benefits of exercise, nevertheless physical…

Revolutionizing the Fitness World Blood. Sweat. Tears. In the world of athletics, these three little words are the epitome of being an athlete. These words are written on the walls of many gyms, weight rooms, and posted on the inside of athlete 's lockers across the world. These words are related to sports such as volleyball, basketball, football, and soccer, just to name a few. CrossFit is changing the world perception of athleticism, and what it means to be an athlete. Also, it is redefining…

and your body starts digging into it 's own reserves to survive, body starts to eat itself and chooses easy to process muscle fibers first, fat…

neuromuscular factors, the loss of neural input to the muscles is ongoing and a lifelong process that is irreversible. When the body loses motor units that innervate several muscle fibers, the neurons that survived attempt to “adopt” muscle fibers. The lower number of motor units functional means the individual has decreased strength and muscle atrophy. The vastus lateralis in 43 male cadavers aged 15 to 83, this study showed total number of muscle fibers was reduced by 50% between the age…

This follow-up study would be a prospective randomized control trial much like the original. Because the original Petrie et al. study had some problems with how small their sample size was and with the size of the pool of participants, a follow-up study should use a larger number of and broader range of participants. At least 150 participants should be enrolled in the study to ensure that the data is more workable than in the original study. Although it might create a better pool of patients to…
