The Exact Cause Of Femoral And Other Hernias

Oxygen debt in the muscles is reached when oxygen levels are much lower than required during strenuous physical activity, causing lactate fermentation to occur in the cells leading to muscle fatigue. The results found in the experiment were the number of squeezes in the first trial for the dominant and non-dominant hands were significantly higher than the remaining ones. The results also showed as the trials continued, the number of muscle contractions decreased steadily which supported the hypothesis. However, there were some increased numbers for the dominant hand from trial 4 to 5 and trial 9 to 10. The non-dominant hand expressed similar unexpected results from trial 6 to 7 and trial 9 and 10. The reasons for these results might be due to the finger muscles being worked at the high intensity for a long period of time causing the muscles to consume higher amounts of oxygen thus producing more ATP production. This would cause the muscles to create more contractions towards the end of the trials. The unexpected results could also be caused by experimental errors such as faulty clothespins. The springs connecting the two ends of the clothespin was tight causing the number of contractions as the trials progressed having a more significant decrease. This is because the amount of energy required to open and close the clothespin would be higher, causing the lactate threshold to occur quicker. Due to this, the number of squeezes would decrease drastically as the trials progressed, in contrast to if the springs were normal. This would change the results by the difference between the trials not being evident therefore, not demonstrating the effects of muscle fatigue. Another factor that altered this experiment was the participant’s condition, Palmar Hyperhidrosis –excessive sweating on the palms – which

friend’s muscles in a stretched position. How does this explain her seeming loss of strength?

Being an athlete I know the struggles of strength and conditioning. Many athletes are pushed in the weight room and during conditioning, however are they being taught the right way? Effective weight training depends on proper technique. Many coaches try to go off of what they know and force their athletes to lift weights. This improper way of lifting often causes injury. The athlete should also lift the proper amount of weights. Athletes today need to know the right way to lift weights. This will allow them to actually gain muscle, power and speed instead of just being sore. There are many factors in weight lifting which include diet, frequency, intensity, and specification. All of these factors play a vital role in developing muscle.

When exercising, the weight or stress you’ve produced to the muscles can create resistance and then contraction of the muscles can be drawn out. These contractions enable the muscles significantly increase in size. Along with the increase in size is the increase in strength as well. Repeated exercise, coupled with weight bearing activities, hypertrophy, and medical term for increase in muscle size, of the muscles will be evident.

The final training method performed for the day was a fartlek exercise. Each repetition was comprised of a 40 second period of full intensity with a 20 second period of slow jogging given as rest. This was repeated three times to complete a full set. It was noted in my training diary that this was a fault due to the work to rest ratio set. Despite my aerobic capacity being deemed ‘excellent’, it was not practical to allow such a higher work than rest. This is because of the training principle ‘progressive overload’ which implies that “the load needs to be slowly increased as we become accustomed to the existing level of resistance to bring about further improvements.” This suggests that training loads should become more intense over a period of time, not increased too abruptly or with too much intensity. As the body has not been given time to adapt to this high training intensity of 2:1, it could lead to the possibility of injury. Implications of injury occurring may lead to fitness levels either plateauing or decreasing. This is due to the training principle ‘reversibility’ which states that “fitness improvements will be lost as training

The biceps femoris muscle is extremely important to most athletes. It is heavily involved during the movements of running, sprinting, stretching, acceleration, and deceleration. A biceps femoris strain can be detrimental to an athlete’s performance and long-term career. Many times a biceps femoris strain will happen because of either over use and wear,

You can get a herniated disc from becoming older. Aging allows these discs to be less flexible and be more vulnerable to breakage. The more common cause of Herniated Disc is by injury to the spine. For example, this can happen when someone picks up a heavy box and suddenly feels a pop in their lower back. A person who suffers from a herniated disc will experience pain, numbness, and sometimes weakness along the the tracks of the nerves.

Muscle fatigue is the process of exhaustion or strength lost, as well as muscular endurance that corresponds with the building up of lactic acid in the muscles (Medical Dictionary) Throughout the lab it was discovered that the greater the number of muscles in the body that are used, the more fatigue builds up, and it becomes difficult to use those muscles. According to table 1.2 and 1.3, there was a decrease in the number of squeezes of a clothespin that were completed in 30 seconds for each of the 10 trials. As the number of trials were increased it became difficult to press the clothes pin quickly and efficiently, causing the fingers’ pace to slow down. The first couple of trials were easily completed without muscle soreness since the

When a muscle is overworked, the muscle can run out of all natural energy. Without energy, the muscle, or muscle pairs, can no longer contract. This condition is known as muscle fatigue. During a state of muscle fatigue, the muscle tissues loses oxygen, and the muscle is left with little to no air.

A possible mechanism that attempt to explain fatigue is the depletion of substrate an the accumulation of product. Limiting Ca2+ and ATP is why the muscle is unable to maintain prolong contraction. ATP is a limiting factor as when there is a decrease in ATP it becomes unavailable to the cross bridges. Ca2+ is responsible for the rate of myosin and actin binding. With limited Ca2+ there is a limited amount of myosin and actin binding therefore there will be a decrease in the force and ultimately the muscle will not be able to contract.

Encephalopcele, ompahlocele, and gastroschisis are all herniations that are of great concern during pregnancy. Diagnostic ultrasound is used to diagnose these conditions, which can aid the physician in putting a treatment plan into action, providing the baby the best possible outcome. While Encephalocele, Ompahocele, and Gastroshcisis are all herniations, they differ in ultrasound images, location, and content of herniation.

Umbilical Hernia is a medical condition in which there formed a bulge in the abdominal region just underneath or right beside the navel. The main reason behind this happening is that the navel wall is damaged and hence either body fat or the small intestine makes its way outwards hence forming a bulge.

The overload principle is the basis for all exercise training programs. For a muscle to increase in strength, the workload to which it is subjected during exercise must be increased beyond what it normally experiences. In other words, the muscle must be overloaded. Muscles adapt to increased workloads by becoming larger and stronger and by developing greater endurance.

This is what causes us to be sore. The muscles then build back up, becoming stronger than before. (lifehacker.com) People still need to be careful when they exercise because they can hurt themselves or overexert themselves while doing it. Being a little sore for a 24-48 hour period is normal but when being sore is a severe pain, it was probably caused by overexertion. (lifehacker.com)

An umbilical hernia happens in infants whose blood vessels do not completely close after birth. These blood vessels feed the fetus. They are located around the belly button. Most umbilical hernias are not a huge concern and will correct themselves with time. Usually by the time an infant is 3 or 4 years old. Incisional hernias result from an incompletely healed surgical wound. Most hernias are due to an excessive amount of strain on a naturally weakened area of the abdomen or other membrane, causing an organ or tissue to protrude (Hernia Symptoms, 2007-2008). But in an incision hernia the weakened area is caused by an incompletely healed surgical incision allowing a hole to develop and organs to be pushed through (Hernia Symptoms, 2007-2008). So like most hernias the strain can be caused by obesity, heavy lifting, coughing or vomiting.
