Mr. Doxtator experiences chronic left knee effusion. An X-ray reveals diminished joint space and osteophyte formation. As a result, Mr. Doxtator lacks 15 degrees of left knee extension, causing him to walk with a limp. Which type of contracture is most likely present?

Mrs. Sanchez is married with 3 young children and has a busy work schedule at a law firm. She was recently evaluated by her physician, who recommended she work with you due to increasing cardiovascular disease risk factors and increasing shortness of breath with activity. When you discussed the ACSM recommendations for cardiorespiratory training at a moderate intensity, Mrs. Sanchez promptly replied that she does not have 150 minutes per week to work out. What would be an appropriate alternative suggestion(s) for this patient?

Malaria only occurs in certain regions of the world where the mosquito vector thrives. Malaria would be considered __________ to these regions. 

Improvement in muscle extensibility attributed to stretching is most likely due to tensile stresses placed on which muscular tissue?

According to ACSM guidelines, for healthy but untrained individuals, maximal improvements in strength are observed with mean training intensities of _____% or greater, although improvements in strength have been observed at levels as low as _____%.  

Calculating heart rate reserve is a more appropriate method of calculating aerobic exercise intensity than calculating heart rate maximum because it takes into account age and resting heart rate.

Contemporary research clearly indicates that the duration of stretching should exceed 30 seconds.

A post-ACL reconstruction rehabilitation protocol includes “quadricep sets” during the acute phase of tissue healing. This exercise is an example of which type of muscle contraction?

Your therapeutic goal is to improve proprioception and kinesthesia in a lower extremity weight bearing position. Which type of exercise training for the lower extremity is most appropriate?

After 3 weeks of training, you decide the patient has greatly increased strength and would like to recalculate the intensity of his resistance training. Besides 1-RM calculation, name one other method you can use to continue to progress the patient’s resistance exercise intensity.
