the correct answer is "I, II, and III only" because these factors are relevant and important to assess before starting a lower body plyometric training program, while "lean body mass" is less relevant in this context.
"5 sets of 5 repetitions" is often considered an optimal volume for building strength. It combines a moderate number of sets with a moderate number of repetitions per set, allowing individuals to use heavier weights while still achieving a sufficient training volume. This approach is commonly used in strength training programs like the 5x5 workout routine and is known for its effectiveness in boosting physical strength.
"Emergency medicine" stands out as the option that doesn't belong in an emergency plan, as the plan primarily focuses on preparedness, response, and communication rather than the actual medical treatment provided during an emergency.
In the context of periodization, the "off-season" corresponds to the training's preparation phase. During this period, athletes focus on building a strong foundation, improving their physical conditioning, and preparing for the upcoming competitive season. The "off-season" is the time when athletes engage in intense training and conditioning work to enhance their performance. It precedes the "preseason," "in-season," and "postseason" phases, making it the appropriate choice for the training preparation phase.
The phrase "impulse" in physics refers to the relationship between force and time. It quantifies how much an object's momentum changes due to a force acting on it over a specific period. In mathematical terms, impulse is calculated as the product of force and time (Impulse = Force × Time). This definition distinguishes it from the other options, as it specifically emphasizes the connection between force and the duration it acts on an object, rather than involving concepts like velocity, power, or acceleration.
"1RM power clean, T-test, 1.5 mile (2.4 km) run, 1RM bench press" because this sequence ensures that fatigue from previous exercises does not significantly impact the outcomes of subsequent tests, leading to more trusted results.
The key factor determining an athlete's sprinting stride length is the vertical force generated during the stance phase. This force allows for a greater lift-off and longer strides. While other factors like horizontal force, flexibility, and stride rate are important, they are secondary to the primary influence of vertical force in stride length.
The answer is "power clean, back squat, hip sled, leg (knee) curl" because this exercise sequence is likely to be the most effective for improving the athlete's explosiveness and ability to drive into defensive linemen in American football.
the "muscle spindle" is the structure where the stretch reflex first appears when there is rapid movement due to its role in detecting changes in muscle length and initiating the reflexive response.
During the inflammatory response phase of a medial collateral ligament (MCL) injury, the affected area is in the early stages of healing, and it is crucial to minimize stress and strain on the injured ligament. Lower extremity plyometric exercises involve high-impact and explosive movements that can put significant stress on the knee joint, where the MCL is located.
Golgi tendon organs in muscle tendons detect tension changes. During PNF stretching, they activate, initiating the "autogenic inhibition reflex." This reflex relaxes the stretched muscle through self-contraction. It signals the muscle to contract briefly, promoting relaxation without shortening. Other options like "reciprocal muscle contraction" don't apply in PNF stretching.
