CSCS Quiz Chapter 20

Communication is essential for the members of the sports medicine team to effectively coordinate and provide the best care for the athlete. Each member of the team brings different expertise and perspectives, and their collaboration ensures a comprehensive approach to the athlete's health and performance. Relying solely on the athlete to relay information between team members can lead to miscommunication, misunderstandings, and potentially compromise the athlete's well-being. Therefore, it is necessary for the members of the sports medicine team to communicate directly with each other.

During the inflammation phase of tissue healing, pain, swelling, and an increased number of inflammatory cells are commonly observed. However, increased collagen synthesis is not a characteristic of this phase. Collagen synthesis mainly occurs during the proliferation phase of tissue healing, where new cells and blood vessels are formed to replace the damaged tissue.

Back squat and pull up are examples of closed kinetic chain exercises. In closed kinetic chain exercises, the distal segment of the body (such as the feet or hands) is fixed and the proximal segment (such as the hips or shoulders) moves. In the case of back squats, the feet are fixed on the ground and the hips and knees flex and extend. Similarly, in pull-ups, the hands are fixed on the bar and the shoulders and elbows flex and extend. Closed kinetic chain exercises are known to be more functional and require the coordination of multiple muscle groups.

The correct order of tissue healing is inflammation, repair, and remodeling. Inflammation is the initial response to tissue injury, characterized by redness, swelling, and pain. It helps remove debris and initiate the healing process. Repair involves the formation of new blood vessels and the production of collagen to restore the damaged tissue. Remodeling occurs later, where the newly formed tissue is strengthened and reorganized to regain its normal function. Therefore, the correct sequence is inflammation, repair, and remodeling.

Microtrauma is caused by repeated, abnormal stresses applied to a tissue through continuous training or training with too little recovery time. This refers to small, repetitive injuries that occur over time due to overuse or excessive strain on a specific area of the body. Unlike macrotrauma, which is a single, sudden injury, microtrauma develops gradually and can lead to chronic pain or dysfunction if not properly managed.

Isokinetic exercise refers to a type of exercise that involves muscle contractions where the length change of the muscle is set at a constant velocity. In other words, during isokinetic exercise, the speed at which the muscle is contracting remains constant throughout the entire range of motion. This type of exercise is often used in rehabilitation settings to help improve muscle strength and endurance, as well as to prevent muscle imbalances. Isokinetic exercise machines are commonly used to provide resistance that matches the force exerted by the muscle, allowing for a controlled and consistent movement.

During the repair phase of tissue healing, collagen fiber production increases to replace the damaged tissue. However, the collagen fibers are not as organized as in the original tissue, leading to decreased collagen fiber organization. Additionally, the number of inflammatory cells decreases during this phase as the inflammation subsides. Therefore, the given answer "Repair" accurately describes the phase in which collagen fiber production, decreased collagen fiber organization, and decreased number of inflammatory cells occur.

A front squat is not an open kinetic chain exercise because it involves the feet being fixed on the ground while the upper body moves. In an open kinetic chain exercise, the distal end of the limb is free to move. In a front squat, the feet remain stationary while the upper body and legs move, making it a closed kinetic chain exercise. Leg extension, bench press, and hip abduction are all examples of open kinetic chain exercises because the distal end of the limb is free to move.

The correct answer is Daily Adjustable Progressive Resistive Exercise. The DAPRE technique is a training method that involves adjusting the resistance based on an individual's progress and their 6 Repetition Maximum (6 RM) working weight. This technique allows for gradual increases in resistance over time, helping to optimize strength gains and prevent plateaus in training.

During the remodeling phase of tissue remodeling, the goal is to optimize tissue function, progressively load the neuromusculoskeletal and cardiorespiratory systems, increase specific joint-angle strength, and engage in proprioceptive training activities. However, only performing open kinetic chain exercises is not a goal during this phase. Open kinetic chain exercises involve moving a specific joint without any weight-bearing on the limb.

Isokinetic exercises allow for maximal resistance throughout the range of motion, meaning that the resistance remains constant regardless of the speed or position of the exercise. This is achieved through the use of specialized machines that control the speed of movement. Isokinetic exercises can be performed with both eccentric (lengthening) and concentric (shortening) muscle contractions. Therefore, all of the given options are correct.

DAPRE stands for Daily Adjustable Progressive Resistance Exercise. It is a type of resistance training technique that involves adjusting the weight or resistance used during each set based on the performance of the previous set. This technique allows for progressive overload, which is essential for muscle growth and strength gains. By gradually increasing the resistance, DAPRE helps individuals gradually challenge their muscles and continue making progress over time.

The exercise range of 20-25 is most appropriate for improving muscular endurance of the calves in a girl's basketball player. This range allows for a higher number of repetitions, which helps to build endurance in the calf muscles. By performing exercises such as calf raises or jumping rope within this range, the girl's basketball player can gradually increase the endurance of her calves, allowing her to sustain repeated movements and perform better on the basketball court.

Neuromuscular control refers to the ability of muscles to respond to sensory information from proprioceptors, which are receptors that detect changes in joint position and movement. This sensory information is crucial for maintaining joint stability during various movements and activities. It allows the muscles to make necessary adjustments in order to prevent injury and maintain balance and coordination.

Macro trauma involves the abrupt occurrence of injuries like slip and falls, blunt force impacts, and frequently, motor vehicle accidents. These incidents are typically characterized by acute manifestations such as swelling, bruising, and potentially fractures.

The correct answer is "Program must be adaptable to each individual." This principle of Rehabilitation and Reconditioning emphasizes the importance of tailoring the program to the specific needs and abilities of each individual. It recognizes that every person is unique and requires a personalized approach to rehabilitation in order to achieve optimal results.

MacQueen's method is matched with the correct description because it utilizes varying sets for different stages of rehabilitation, including beginning, intermediate, and advanced. Additionally, it uses a set of 10 RM (repetition maximum), which means performing an exercise with a weight that allows for only 10 repetitions before fatigue sets in. This method allows for progression and adaptation as the individual's strength and ability improve throughout the rehabilitation process.
