There is also an increase in the synovial fluid at the joint. The short term effects of exercise on your muscle may result in the joints become less viscous because the fluid allows a larger range of movement and pliability. The musculoskeletal response has an effect on the flexibility of the muscles during and after exercise. During exercise I got 18 cm in the sit and reach test and post exercise was 17 cm this shows that exercise has an effect on muscle pliability during acute exercise. Muscle fibre micro tears During exercise your muscles are put under stress due to constant contractions this stress can then lead to tears in the muscle fibres, if the body has the correct nutrients during recovery periods the muscle can then repair itself and become stronger this can lead to a increase in muscular endurance.
Fitness training methods description. Circuit training: Is a form of body conditioning or resistance training using high-intensity aerobics. Involves all components of fitness, may contain loads of stations. Continuous training: Is a type of physical training that involves activity without rest intervals, as for example doing some fitness, and shortening the resting times. Resistance training: Is a type of physical exercise specializing in the use of resistance to
The type IIb fibers are the most fatigable out of all the fibers but also generate the most power and force, and therefore are the fastest twitch muscles fibers. These types of fibers are recruited in activities that require an all out burst of power and only act for an extremely short period of time, as the total length of their contractions usually last only 7.5 milliseconds. In terms of general recruitment, they are also the last to be recruited. For example, upon normal activities, slow twitch fibers are recruited first, followed by type IIa when the type I can no longer

Unit 2: The Physiology of Fitness Assignment: No 1 Task 1.a Task1b Musculoskeletal response Increased blood supply The short term effects of exercise on your muscles include an increase in temperature and metabolic activity. Result: - greater demand for oxygen in blood supply through capillary dilation. Increase in muscle pliability When you warm up your muscles during activity makes them more pliable and reduces the risk of injury. Increased range of movement The short-term effect of exercise are demonstrated by changes within the joint. Movement of joints stimulates the secretion of synovial fluid.
LABORATORY REPORT Activity: Recruitment and Isotonic and Isometric Contractions Name: Carolyn Chrzastowski Instructor: Professor Waite Date: 07.19.2015 Predictions When the arm goes from resting to flexing, the amplitude and frequency of sEMG spikes will increase During flexion, the amplitude and frequency of sEMG spikes will ___ during extension. be greater than Recruitment of motor units will be greatest when the load is 20 pounds Materials and Methods Comparison of motor unit activation during muscle tone and concentric and eccentric isotonic contractions Dependent Variable amplitude and frequency of sEMG spikes Independent Variable muscle movement Controlled Variables total number of motor units
Test- Running circles around the stadium, in precise time, as for example how fast can you run 10 laps around the stadium. By the time doing it, there will be chances of improving. Flexibility. Definition- Muscle capability to flex further also stretches joints. By doing flexibility training, sportist can easily get more flexible muscles, and joints, easy to improve on flexibility.
Which of the types of stretching techniques is seldom recommended in sedentary individuals due to the potential for causing muscle soreness? a. ballistic b. static c. PNF d. strength 35. Body composition refers to the different types of tissues that make up your body. The primarily include: a. muscles and bones b. tendons and ligaments c. skin and fat d. all of these 36. Fast-twitch muscle fibers are more useful in long-term endurance activities such as running or swimming a.
Another component would be dynamic strength which is repeating a movement using muscular force. You need this because you need to be able to repeatedly hit the ball with sufficient force. Explosive strength is another factor that is needed. Explosive strength is where muscular effort is in one burst. You need this
Since your body’s temperature is high and muscles are already active after a hectic day, your muscles can perform better. • Chances of injury: Being sleep-deprived, you reach the gym and start compensating by sleep-walking on the treadmill. Is that going to yield result? You get injured due to lack of concentration and energy. Better you keep your evenings for workouts.
