Previous research into the area of sprint performance has focused on what type of training can be done to improve performance (Whitney et al., 2005). A common method used is repeated practice of the performance of a sprint (Edge et al., 2005). This induces a learning effect; this learning effect is the improvement in performance through continued repetitions (Gibala et al., 2006). An alternative training method used by coaches for training purposes is the use of resistance training to increase skeletal muscular strength, the hamstring group, gluteus maximus and adductor magnus are considered the most important skeletal muscles in speed production (Delecluse, 2006). High velocity strength training uses exercises that train the muscles to recruit the fastest motor units (Delecluse et al., 1998). The motor units that can produce the most rapid contractions are the neuromuscular pathways that will become developed to allow a rapid response to signals inducing muscular contractions (Wilmore et al., 2008).
Other training methods include the use of resisted sprints. These resisted sprints will use equipment such a towing sled, resistance parachutes or weighted vests. The use of this equipment can increase the resistance and help produce increased stress on the muscle and a training effect while not affecting the kinematics of the performers sprint (Duthie, 2006).
Sprinting is categorised into stages: the acceleration phase (0-10m), the maximal running speed phase (36-100m) and a transition phase in between (Delecluse, 1997).
Other inclusions into an athlete’s training regime may include the use of Olympic lifts. These techniques have been shown to increase the power and strength of muscles, at a greater extent than power lifting or res...

...he eccentric phase, the more energy there is available to use in the concentric phase; therefore allowing more work to be done in the concentric phase. Mechanism Three, Force Potentiation suggests that cross-bridges that are formed can have increased power output as a result of the previous training. This only occurs within muscles that have long lengths as it affects the amount of cross bridges that can be formed. The fourth and final mechanism is the suggestion that a stretch reflex can be induced by the force lengthening of the muscle at the beginning of the SSC. The use of the strength shortening cycle is also in effect within Olympic weightlifting movements.
The purpose of this study would be to investigate the intervention of Olympic lifting into a performers training regime and observe the effect of improving performance through the use of the intervention.
As we have learned through our reading, most all bodies skeletal muscles are made up of primarily three types of skeletal muscle fibers, but their proportion differs depending on what action the muscles is doing. For example, type I fibers such as muscles of the neck, back, and leg have a higher proportion. According to Quinn (2014), type I muscles are slower and more effective, they tend fire a lot slower than fast twitch fibers and they fatigue at a much slower rate. Hence, slower twitch fibers are pronounced at helping athletes run marathons and bicycle for hours. Shoulder and arm muscles are not always active but are intermittent in their use; these muscles tend to have a larger amount of tension for uses in throwing and lifting. These muscles have a combination of both type I and type II B fibers. These fast twitch fibers use anaerobic metabolism to create energy and are the "classic" fast twitch muscle fibers that excel at producing quick, powerful bursts of speed. These muscles are used in events such as 100m sprint, basketball, soccer and football. Since this muscle fiber fires at such a high rate of contraction it will fatigue much faster and will not last long before needing to rest.
Evidence of lifting weights can be traced back to the origins of man. As far back as cave painting and scrolls, there exists evidence of weightlifting. Initially as an expression of strength, to competition and functional training, weightlifting has carved its path through the ages. It has taken on a new role in the modern world; athletic training. With an entirely new emphasis in sports on speed, strength, and flexibility; weightlifting is more popular than ever. Unfortunately, young athletes often do more harm than good by injuring themselves lifting. When these uneducated lifters try to jump right into a program, lifting more than they should, an injury is imminent. What is overlooked, is that when weightlifting is done correctly, it has a great potential to prevent injuries instead of cause them. Understanding how the body works, using proper technique on the appropriate lifts, and participating in regular physical activity can greatly reduce the risk of athletic injuries.

The world of sports and athletics has become inundated with ways to get fit, trim fat and build muscle. The truth be told there are no quick fixes or workout plans that work the exact same for everyone. Many factors play into the effectiveness of a successful workout program. There are just as many techniques of working out as there are factors to success. Finding which workout technics work for each athlete or client can be the difference between mediocre progress and phenomenal progress. A few of the workout technics that stand out amongst the pack are Forced Repetitions, Periodization (cycling), Pyramid System and last but certainly not lest Super Sets. The afore mentioned techniques span beyond the basic iron pumping mentality of weight training and narrows the scope of training down to a more scientific application. For the purpose of this research a more in-depth look will be taken into each technique and then further identify any similarities and or contrasts.

After testing, the team did a 5 yard sprint progression. This sprinting progression consisted of sprinting 5 yards 5 times consecutively. After 5 reps of sprinting, the repetitions were drop set to 4, 3, 2, and then 1 sprint. This progresion was done 2 times.
I am keen to discover new optimal techniques for enhancing sports performances, analysing the human body to determine the safest method for performing a particular exercise. I desire to help athletes’ enhance their techniques through accurately calculated advances based on evidence about movement. My fascination in helping athletes will aid my ability to become a sport biomechanic

The transfer of training effect = This principle states that every exercise can help to improve a competition lift to a varying degree. Movements that more closely mimic a competition lift will have high degree of carryover. Lifting variations for this program were chosen based on how closely they mimic the competition
Runners are always looking for ways to become faster. An easy way to drop tremendous time and make the entire running experience easier is to improve running form. Culture has a great impact on running form; from African to Mexican tribal runners, to commercialization of strange alternatives to mainstream footwear, culture impacts every one of us. The lower body plays an obvious role in running, with emphasis on the calves, quadriceps and hamstrings. The upper body plays a key role in running as well, although its purpose is not always agreed upon. Together, these three areas come together to make or break every runner’s form.
The study of biomechanics has made abundant contributions to sport over many years which have been applied to improve athletes’ physical performance. The knowledge of human movement and how internal and external forces of the body influence movement has been used to enhance performance by finding methods of change to technique which can improve the overall performance of an athlete and also in finding the mechanisms that affect the occurrence of sports injury (Bartlett, 2002, p 2). The most common method for improving performance in any sport is by improving the technique, which can be achieved by first applying a biomechanical analysis giving detailed analysis of sports movements. A biomechanical analysis is important as it allows for the
Traditional body weight exercises such as push-ups, planks, and crunches require an athlete to be limited in range of motion as some portion of their body is resting on the ground, on a stable platform. Usually, the motions of these particular exercises are occurring in one or two planes. To expand these motions in all three planes, the athlete would need to have space underneath his or her body. One of the many forms of resistance training uses a collection of ropes, cords, anchors, and/or pulleys suspended from above to lift a portion of an athlete’s body as the person holds on to handles. The athlete
Muscular fitness is a key component to leading a healthy and active life. Muscular fitness is composed of two main aspects, muscular strength and muscular endurance. The American College of Sports Medicine (ASCM) defines muscular strength as “The ability to perform activities that require high levels of strength” and defines muscular endurance as “The ability of a muscle group to execute repeated contractions over a period of time sufficient to cause muscular fatigue” (ACSM, 2014, p. 3). Day to day activities such as lifting, carrying, and putting down objects require a certain level of functional muscular strength and muscular endurance.
Toward the end-scope of each activity, you may well be "lifting" more than you ordinarily would utilizing a barbell or dumbbell. That can convert into more quality all through a muscle's whole scope of movement.
