FREE NSCA CSCS Health & Safety Questions and Answers
Where should the dumbbells go in a new free weights room while it is being designed?
The facility's perimeter should have free weights put there so that there are open, unimpeded passageways. A safe, distinct area where athletes can safely practice free weight exercises should be designated for them. Injury risk is increased in all other areas.
Where does fatty acid oxidation take place in the cell?
Fatty acid oxidation takes place in the mitochondria of humans. Prokaryotes do it in the cytosol, but we are not including them in the definition of strength and conditioning.
One of your athletes, who you are coaching on a basketball team in the weight room, complains of acute agony while performing a walking overhead lunge. Which of the following would be the best course of action? She claims the discomfort started after a tumble during the game last night and returned as soon as she tried to raise a plate over her head.
The athlete should be taken right once to the physiotherapist or athletic trainer. Collaboration between the head coaches, physiotherapists, and other support staff members is crucial. Tell the athletic trainer that this is a fresh injury so they may perform a thorough evaluation. Since you are in the middle of guiding a session, it's unlikely that you can tell how serious the injury is. The problem might not be that significant, or any change could make it worse. A unwarranted panic may ensue if parents are contacted before the severity of an injury is known (apart from emergencies).
Which of the following would be the best update for a football strength and conditioning facility that has both indoor and outdoor space?
Football players should focus on establishing leg drive at low body angles rather than using battle ropes, rings, or an isokinetic machine. A sled could be used for single leg strength development, rehabilitation, and sport-specific training.
Which of the following benefits of effective warm-up design does not result in improved performance?
Short-term range of motion can be increased by warming up, but following activity, flexibility will revert to pre-warm up values. But during a warm-up, increasing heart rate and blood flow reduces muscular resistance and increases suppleness. Greater dynamic range of motion is made possible in following action. A strong warm-up also results in faster muscle contraction/relaxation through sport-specific motions, which improves strength and power output as well as reaction speed. The effects of static stretching on later athletic performance are minimal.
Which stage of the General Adaptation Syndrome does an athlete enter when they start to supercompensate and adjust to additional stressors?
Temporary adaptation and the physical capacity to face the new demands characterize the resistance stage. Due to the new challenge at this phase, performance exceeds that of homeostasis, the initial stage. The fresh stressor causes tiredness and a brief decline in performance during the alert stage, which follows homeostasis (again, the beginning level of ability). The exhaustion stage, which comes last, is a sign of overtraining, which occurs when a strain is too great, lasts too long, or is not followed by enough time to recover.
Protein has _____ calories per gram.
Dietary protein has four calories per gram. A gram of fat has nine calories per gram, compared to four for a gram of carbohydrate.
What one of the following best defines how to recognize a hang power snatch?
Instruct the athlete to push the bar away and drop it if they fail the lift with the bar in front. Have the athlete release the bar backward while jumping forward if it becomes unstable when they grab overhead or behind. Always keep the space around the platform free, and begin by practicing safe practices with light loads.
The bar makes contact with the body at the ___________ when doing a barbell hang clean.
Before beginning the hip hinge, an athlete should adjust the location of his or her hands so that the bar rests on the mid- to upper thigh. If the athlete holds the barbell as near to the body as possible during triple extension, this will enable maximal force to be applied to the bar. However, because of the wider grip used in a barbell hang snatch, the barbell rests higher along the hip crease. A hanging movement does not involve any lower point of contact.
You are tasked with creating a plan for a collegiate wrestling squad in order to get ready for the forthcoming season. Which of the following exercises should you include in your program to train upper body stability using closed-chain movements?
Suspension or TRX rows are regarded as upper body closed-chain exercises because the limbs do not move while the body does. Goblet squats are a closed-chain exercise, however their main emphasis is on the lower body. Pallof presses and neutral-grip lat pulldowns are open-chain exercises.
How many repetitions of an exercise would you plan to perform when training for maximum strength at 85% of 1RM?
While it is possible to perform 1-2 reps at 85% of one's 1RM, training for maximum strength necessitates working at one's limit. This set/rep pattern is better suited for maintaining strength.
