Agility refers to the skills and abilities required to explosively change movement velocity and modes. It involves the ability to quickly and efficiently change direction, accelerate, decelerate, and react to unpredictable stimuli. Agility is important in sports and other physical activities that require quick movements and rapid changes in direction. It allows individuals to move quickly and effectively in various directions, making them more responsive and adaptable in dynamic situations.

The given answer "elite" suggests that in elite sprinters, the front hip angle is 40 degrees and the rear hip angle is 80 degrees. This implies that elite sprinters have a more open front hip angle and a more closed rear hip angle compared to other sprinters. This could be due to the elite sprinters' superior technique and flexibility, allowing them to generate more power and speed during their sprints.

Arm action is important for athletes to effectively perform multidirectional tasks because it helps with balance, stability, and coordination. The arms play a crucial role in generating force and power during movements such as throwing, hitting, or reaching. They also assist in maintaining body control and providing counterbalance during rapid changes in direction. By utilizing proper arm action, athletes can enhance their overall performance and optimize their ability to perform multidirectional tasks effectively.

Fatigue is a natural response to intense physical activity that can hinder strength and skill development. When the body is pushed to its limits, it becomes tired and depleted of energy, leading to a decrease in performance. This can prevent the individual from fully engaging in their training or practice, limiting their ability to improve their strength and skill levels. Therefore, fatigue is a common obstacle that needs to be managed and overcome in order to achieve optimal physical performance.

Stride frequency and stride length are two factors that contribute to an individual's running speed. Stride frequency refers to the number of strides taken per unit of time, while stride length refers to the distance covered in each stride. By increasing either or both of these factors, a runner can increase their overall speed. Therefore, the correct answer is stride frequency and stride length.

The question is asking for the type of tasks that involve various changes in speed and direction, including initial speed and direction, increases or decreases in speed, redirection, and final speed and direction. The term that encompasses all these changes is "changes in velocity."

The level that corresponds to medium term planning in program design is known as a mesocycle. Mesocycles are typically 4-6 weeks long and involve a specific focus or goal, such as building strength or improving endurance. They are an important part of periodization, which is the systematic planning of training to optimize performance. Mesocycles allow for progressive overload and adaptation, helping individuals reach their desired fitness or performance outcomes.

Discrete skills refer to activities or movements that have a clear and distinct beginning and end. These skills are often seen in athletic activities where specific actions or movements are performed, such as throwing a ball, kicking a soccer ball, or shooting a basketball. These skills can be easily identified and measured as they have a definite start and finish.

A closed agility skill is one in which the athlete does not rely on external factors or cues to determine when to change direction and velocity. In closed skills, the environment is stable and predictable, allowing the athlete to plan and execute their movements without needing to react to external stimuli. The T-test is an example of a closed agility skill, as the athlete follows a predetermined pattern and does not need to adjust their movements based on the context or situation.

Sprint resistance refers to a method used to enhance explosive strength and stride length in athletes without restricting their movement mechanics. It involves providing resistance during sprinting exercises, which forces the athlete to exert more effort and power to overcome the resistance. This training technique can help improve the athlete's ability to generate force and power, leading to increased speed and performance in sprinting activities.

Special endurance refers to the ability to repeatedly perform maximal or near maximal efforts in exercise patterns that are specific to a particular competition or sport. This type of endurance is crucial for athletes who need to sustain high-intensity efforts over an extended period of time, such as long-distance runners, swimmers, or cyclists. It involves a combination of cardiovascular fitness, muscular strength, and mental resilience. Special endurance training aims to improve an athlete's ability to maintain a high level of performance during the later stages of a competition when fatigue sets in.

Mental practice refers to the process of mentally rehearsing or visualizing a task without physically performing it. This type of motor learning practice is highly beneficial for preperformance preparation as it allows individuals to mentally simulate the task, enhancing their cognitive understanding and motor planning. By engaging in off-task visualization, individuals can improve their performance by mentally practicing and preparing themselves before actually performing the task. Mental practice helps in developing muscle memory, improving focus, and boosting confidence, making it an effective tool for enhancing performance.

In speed or agility sessions, the measure of work is determined by both the volume (amount) and intensity (force) of the exercise. The term "volume-load" refers to the combination of these factors, where volume represents the distance or duration of the exercise, and load represents the force or intensity applied. Therefore, volume-load is the correct answer as it encompasses both the work volume and intensity in speed or agility sessions.

Sprint resistance and sprint assistance are both secondary methods of developing speed. Sprint resistance refers to any form of training that adds resistance to sprinting movements, such as running with a parachute or pulling a sled. This type of training helps to build strength and power, which can improve sprinting speed. On the other hand, sprint assistance involves using external aids or devices, such as bungee cords or downhill running, to help increase stride length and speed. Both methods can be effective in improving overall sprinting performance.

The correct answer is "None of the above." This means that maximum velocity running (sprinting) consists of ground preparation, braking, propulsion, and recovery. In other words, all of these elements are involved in achieving maximum velocity while sprinting.

To achieve a faster sprinting speed, it is important to focus on reducing the time your foot spends on the ground during each stride. By emphasizing brief ground support times, you can increase your stride rate, which refers to the number of strides you take in a given time period. This means that you will be able to cover more ground in less time, resulting in a faster sprinting speed. Therefore, the correct answer is increased stride rate, rapid stride rate, and greater stride rate.

Strength is not considered a component of coordinative abilities because coordinative abilities primarily involve the integration and control of body movements, rather than the raw power or force produced by muscles. Coordinative abilities include balance, combinatory ability, rhythm, and differentiation, all of which contribute to the efficient and effective execution of motor skills. Strength, on the other hand, refers to the ability of muscles to exert force, which is important for tasks requiring power and resistance, but not necessarily for coordination.

Tactical metabolic training is a form of special endurance training that focuses on competitive exercise relief patterns, allowing for maximum effort in minimal time. This type of training is designed to improve overall performance and stamina, making it a suitable answer for the given description.

To increase the stretch-shortening cycle, skillful, multi-joint movements are necessary as they involve multiple muscle groups and joints, allowing for greater force production and energy storage. Forces transmitted through the kinetic chain are also important as they enable efficient transfer of energy from one body segment to another, enhancing the stretch-shortening cycle. Brief work periods are required to maintain the explosive nature of the movements and prevent fatigue from compromising the stretch-shortening cycle. Simple movements, on the other hand, may not fully engage the stretch-shortening cycle and may not facilitate the desired improvements.

Late support refers to the phase of sprinting where the foot is in contact with the ground and is supporting the body weight. During this phase, the hip flexors are lengthening eccentrically, the knee extensors are contracting concentrically to extend the knee, and the calf muscles are contracting concentrically to flex the foot. This phase occurs after mid flight, when the foot is transitioning from being off the ground to being in contact with the ground again.
