The topic I chose to discuss for this week’s topic of lower limb extremity movements is a lunge. A lunge is classified when the human body has one leg located forward with the knee bent at a 90-degree angle and keeping in line with the foot which is flat on the ground while the other leg is positioned behind, and/or when one leg is out to the side in a similar manor of 90 – degrees and keeping the knee in line with the foot which is flat on the ground, and the other leg stays facing the front. As an alternative, plyometric lunges can be achieved by jumping explosively between lunge positions. A lunge can be performed using bodyweight, dumbbells, a barbell, or kettle bells to increase strength over time and heighten the level of difficulty. Lunges tend to focus on forming and strengthening the hamstrings, quadriceps, and the gluteus maximus muscles. …show more content…
Within this portion of the course, we are looking at the pelvis and hip complex, as well as the knee and ankle regions. The lunge movement encompasses all of these muscles and joints. Furthermore, we can see on page 207 of the reading where the potential of injuring a knee is one of the highest accounting for 25% to 70% of reported injuries (Hamill, J., Knutzen, K. M., & Derrick, T. R. 2015). Thus, this article allows us to dive into the pain and how it effects a lunge movement, and more so, how we can help work with instead of against the pain to help prevent further pain, and or lessen the pain for the future. In turn, I found the article to be very informative and remind me that even a pain within the foot can influence all the way up to the hip, and vice versa. Thus, the complete take I got on this was, to be careful when performing any movement as one mistake could cause a domino effect of injuries. More so, it is important to make sure you listen to your body, and if you are experiencing pain to properly alter the movement as

Kinesiology can be defined as the study of mechanics of body movements, so I think that is very important to know the meaning of movement when studying kinesiology. Everything in kinesiology has to do with the movement. Every action the body takes is a movement which is what kinesiology is. You cannot be successful in the field of kinesiology no matter what you are doing if you do not understand what movement is. It is the study of human movement, performance, and function by applying the sciences of biomechanics, anatomy, physiology, and neuroscience. It looks at movement and which muscles are involved to create movement relating to strength exercising and sports technique. Movement is an act of changing physical location or position or of

This skill involves jumping in the sagittal plane about the transverse axis. It consists of hip, knee, ankle, and shoulder joints. In the preparation phase in propulsion, the subject has flexed knees and hips which will need to be straightened by the strength of their corresponding joints such as the hinge joint at the knee joint. The hip joint is a ball and socket joint that bears the body weight and allows for jumping motion. During th...
The muscular system is the set of all the muscles that make up the human body. It is an extensive system of muscles and nervous tissue, which is distributed all through the body. In total, the human body consists of approximately 650 muscles. The muscular system is divided into three types of muscle: cardiac muscle, smooth muscle, and skeletal muscle.

In understanding the factors contributing to the mechanism of non-contact ACL injury, investigators should consider whether the kinematics, kinetics and muscle activation strategies observed are the cause of increased ACL strain or compensation for other kinetic chain insufficiencies ²⁹. Further knowledge on how movement patterns and other kinetic chain structures affect ACL loads prove critical in enhancing future prevention strategies ²⁹ ³⁴. As with reconstruction, rehabilitation should aim to aid the knee in attaining its near-normal function ⁵⁵. Through producing rehabilitation programmes built around existing knowledge on the biological and mechanical properties of the ACL, objectives such as reduced pain, greater ROM and improved muscle function can be achieved ⁵⁵.
Every part of our body is a science. I never imagined the hidden science in the movements of the body. The science of kinesiology is the science of body movements. I grew up watching my grandma and the changes in her body as both of us got older, I could walk and balance properly while she lost it. I always felt bad when she was not able to get up and walk properly and as caring grandson I always gave her my hand. It was a great feeling for me to take care of her in her last days. Her difficulty in moving always pointed me to do something for her and I landed doing kinesiology- the science of human movements. I completed my high school at Cathedral High School in West Texas. I was an active member of National Honor Society as well as Spanish Honor Society. I held the treasurer position for one year in the society, which I felt proud of. I was not excellent at my academics, was just an average student struggling with the subjects of chemistry and anatomy. It is strange at one point of time suddenly when u come across a certain situation or an accident and u just realize your dream and...
Throughout literature countermovement jumps (CMJ) are seen to be higher in contrast to squat jumps (SJ) (Bobbert et al. 1996; Kubo et al. 1999; Bobbert et al. 2005). However present literature regarding the key potential mechanisms behind why greater muscle forces are seen accelerating the body upwards in CMJ in comparison to SJ is somewhat unclear. A CMJ can be defined as a positioning starting upright, beginning the descending motion in advance of the upward motion in contrast to a SJ where the start position is squatted with no preparatory countermovement (Akl 2013). The higher jump heights seen in CMJ in comparison to SJ are apparent even if at the start of propulsion phase the body configuration is identical (Bobbert et al. 1996). In past literature three main mechanisms have looked to provide an explanation for the greater muscle forces seen in CMJ than the SJ. The first plausible theory is that the muscle stretch in CMJ increases the production of force capability of the contractile machinery (Edman et al. 1978; Ettema et al. 1992; Herzog et al. 2003). Secondly the assumption that the muscle fibres are on the descending limb of their force–length relationship at the start of propulsion in the CMJ and SJ, however in CMJ the stretching of a chain of elastic components, they are not as far past optimum length therefore allowing a greater force over the initial phase of their shortening range, with the stretching of sequences of elastic components, this then causes the storage of elastic energy that is then reutilized in the propulsion phase (Ettema et al. 1992). The final explan...

The focus of this paper is mechanically and automatically break down the deadlift. It focuses on the four phases of the deadlift (The lift off, pull through, the lockout, and the lowering phase) as well as the muscles involved in lifting and lowering the load. The sole purpose of the deadlift is for health and fitness. It is a core lift that works nearly every muscle in the body. Muscles from the lower and upper extremities will go through a period of flexion and extension when moving through the phases. The deadlift should be performed safely, and with proper form to avoid injury. This paper shows and demonstrates the proper form of the deadlift. There are also a number of forces acting on the load and the athlete. Gravity and external forces will be an active part of lifting the load. Images and tables are provided in the paper to better understand the movements and muscles used when performing the deadlift.

The purpose of the squat is to train the muscles around the knees and hip joints, as well as to develop strength in the lower back, for execution of basic skills required in many sporting events and activities of daily living. Because a strong and stable knee is extremely important to an athlete or patient’s success, an understanding of knee biomechanics while performing the squat is helpful to therapists, trainers, and athletes alike (11). Because most activities of daily living require the coordinated contraction of several muscle groups at once, and squatting (a multi-joint movement) is one of the few strength training exercises that is able to effectively recruit multiple muscle groups in a single movement, squats are considered one of the most functional and efficient weight-bearing exercises whether an individual’s goals are sport specific or are for an increased quality of life
My understanding of kinesiology prior to enrolling in the course, is that I knew kinesiology is the scientific study of human movement , and that it involved sports and exercise and physical activity.I 'm interested in kinesiology , because I love anything that has to do with sports, and to get more of a detailed report on how human movement plays such a big role in the sports world.I have played sports for most of my life my interests our football, basketball,baseball.I started football my eighth grade year, and continued to play threw high school, until I tore my meniscus and mcl so I skipped my junior year of football , and came back my senior year had a really great season started at right offensive tackle.Missing my junior year in football really took a toll on me ,I could have gained so much more experience playing if so. I 've played basketball probably since the third grade , and continued to play threw high school even threw my knee injury ,I played travel basketball as well a

Lunges and squats are often referred to as the masters of lower body exercises. In addition to your legs, theses functional, compound exercises also work your buttocks. However, poor form, a muscle imbalance, the consistent overload on your knees, and the repetitive motion, can make these exercises wreak havoc on your knees. (See References 1) Not to fear, you can still strengthen and shape your glutes with do-able, effective exercise that are easy on your knees.
