Introduction
Concurrent training can best be described as an attempt to combine endurance training and strength training within a training programme in an attempt to improve both strength and endurance simultaneously.
When thinking about the term interference we can sometimes associate it with conflict between two or more identities, strength training is often used due to the highly anaerobic nature of the activity, in order to attain certain physiological outcomes that may be beneficial for sports performance (Harries, Lubans & Callister, 2012). In team games strength and conditioning coaches utilize exercises in a gym setting, which they hope will bring about adaptations in muscle size, strength and hypertrophy. To do this coaches must come up with suitable training programmes that don’t cause unnecessary fatigue to the athlete and suit the requirements of the sport and what the technical coach wants. In rugby there are a lot of areas of the training where there are demands for anaerobic and aerobic exercise; so the ability to perform well in both aspects is desirable (Impellizzeri, Rampinini & Marcora, 2005; Maud, 1983; Morton, 1978). During the interference effect some of the aerobic training that the players may do (like a 2km run) may have detrimental impacts on ability to perform anaerobic activity later on (Hickson, 1980 and Hunter, Demment & Miller, 1987), this is thought to be due to a build-up of hydrogen ions within the muscle (Cooke, Franks, Luciani & Pate, 1988). Hickson, (1980) suggests that during a strength training programme adding endurance training to the same programme inhibits muscle strength improvements.

... the depletion of muscle glycogen and a reduction in pH on a cellular level (Coyle et al., 1983; Sahlin, Tonkonogi & Söderlund, 1998). In moderate – high intensity anaerobic exercise fatigue can be linked to a reduction in pH level with depletion in ATP stores and muscle glycogen depletion playing a small role (Reilly, 1997). In very high intensity exercise fatigue could occur when there is either an increase in ADP, inorganic phosphate or a reduction in muscle pH however a specific cause is hard to identify (Lambert & Flynn, 2002). Other limiting factors might include the effect that metabolic acidosis has, by limiting contraction force output of a muscle (Bogdanis, Nevill, Lakomy & Boobis, 1998), the accumulation of ammonia (Brouns, Beckers, Wagenmakers & Saris, 1990) and the reduction in the ability of the sarcoplasmic reticulum to release calcium (Favero, 1999).
The data collected during this experiment has shown that a relationship likely exists between the rate of muscle fatigue and the time spent performing vigorous exercise prior to the set of repetitive movements. This is likely due to a build-up of lactic acid and lactate as a result of anaerobic respiration occurring to provide energy for the muscle cell’s movement. As the pH of the cell would have been lowered, the enzymes necessary in the reactions would likely not be working in their optimum pH range, slowing the respiration reactions and providing an explanation to why the average number of repetitions decreased as the prior amount of exercise increased.

In this lab, we explored the theory of maximal oxygen consumption. “Maximal oxygen uptake (VO2max) is defined as the highest rate at which oxygen can be taken up and utilized by the body during severe exercise” (Bassett and Howley, 2000). VO2max is measured in millimeters of O2 consumed per kilogram of body weight per min (ml/kg/min). It is commonly known as a good way to determine a subject’s cardio-respiratory endurance and aerobic fitness level. Two people whom are given the same aerobic task (can both be considered “fit”) however, the more fit individual can consume more oxygen to produce enough energy to sustain higher, intense work loads during exercise. The purpose of this lab experiment was performed to determine the VO2max results of a trained vs. an untrained participant to see who was more fit.
Muscle endurance is the ability to perform a lot of repetitions against a given resistance for a long period of time. The combination of strength and endurance results in muscle endurance. Muscle endurance is used in may sports such as rowing, swimming, cycling, distance running, field hockey and American football. Normally, an endurance muscle program involves lifting about 12-25 repetitions of moderate loads. In some cases, this is inadequate for many sports such as boxing, canoeing and x-cross skiing.
The progressive overload principle is exemplified in strength training, which is necessary to improve the performance of a 100m sprinter.
“Accept the challenge so that you can feel exhilaration of victory”. This quote was said by George S. Patton is discussion the important role that Athletic trainer should work and work until they win. Who are we are highly qualified multi skilled health care professionals. Also Athletic trainer prevent diagnosis treatment and rehabilitation of emergent acute or chronic injuries. Were also known for being high qualified multi skilled health care professional. Being and athletic trainer is a great and hardworking career. That involves meeting new people, dealing with different challenge each day, Also it has moderate schooling.

For purpose of emphasis and understanding, some background information is needed to fully understand exactly what blood doping can do for an individual. In order for muscles to perform, they need a ready supply of oxygen. During high intensity exercise, oxygen is depleted and the body can not get enough oxygen to the muscle in order for them to perform their optimal potential. This lack of ability to get oxygen to the muscle is called oxygen debt and results in lactic acid being formed. Lactic acid is a waste product of anaerobic cellular respiration within the muscle tissue, which can cause muscle sourness that, usually, is felt after a hard or long workout. Fatigue usually sets in with the onset of lactic acid production. Oxygen is carried to the muscle by two delivery systems. Three percent of oxygen is carried in plasma and ninety-seven percent is in hemoglobin, the principal protein in erythrocytes (red blood cells). If hemoglobin amounts are increased, this will lead to increased oxygen levels that can be transported to the muscles. Allowing the muscles to become more fatigue resistant.
Cellular respiration is an important function for the body to obtain energy (Citovsky, Lecture 18). There are two types of cellular respiration; aerobic conditions and anaerobic conditions. Aerobic conditions are the cellular respiration occurred with oxygen while anaerobic conditions are cellular respiration occurred without oxygen. The most common cellular respiration is aerobic conditions where oxygen were supplied for phosphorylation (Campbell et al., pg 177). In human body, anaerobic conditions occurred when muscle cells are overworked and oxygen is depleted before it could be replenished (Citovsky, Lecture 19). This is a common phenomenon during exercise. The accumulation and production of lactic acid from anaerobic cellular respiration has been always a cause of muscle sore from intense exercise (Campbell et al., pg. 179).
Athletic staleness and burnout is a big problem for many of today’s athletes whether they are at the amateur or professional level. The good thing about this problem that ends up in total and complete physical and emotional exhaustion is that it can be recognized when it is taking place. It can also be treated if the recognition comes at too late of a stage of the onset of staleness and burnout. But the best remedy for athletic staleness and burnout is prevention of it in the first place. There are three different models that have been used to explain the causes of athlete burnout.

In order to fully understand the impact and effect of overtraining, defining and establishing the difference of what overtraining is from other conditions, such as overreaching, is necessary. Overtraining is defined as the accumulation of both training and non-training stresses producing a long-term effect on the athlete’s performance capacity, with or without physical and psychological overtraining signs and symptoms in which recovery of the performance capacity will take weeks to months (Halson, 2004 p. 969). Overreaching, however, is defined by the accumulation of training and non-training stresses with a short-term effect on the a...
weight lifting is a very good way to get stronger. As well as a way to stay healthy as long as you do it right with good form and positioning. It’s good for people to lift some weight for sports and other physical competition. Most people that do weight lifting are athletes or people that are trying for the better healthy lifestyle.
There are a lot of things going on in the body when exercising. When working out for a while the body soon realizes that it’s not stopping anytime soon and the body goes into aerobic respiration and responds with oxygen. “Aerobic respiration is when oxygen is taken in and carbon dioxide is produced. When exercising, every part of the body starts
