It is very costly, and in most cases impractical, to measure 24-hour energy expenditure or to monitor physical activity energy expenditure through either direct or indirect calorimetry. The most plausible tools for measuring either 24-hour energy expenditure or physical activity energy expenditure in the field are pedometers, accelerometers, and heart rate monitors. A popular physical activity diary for older children and adolescents is the Previous Day Physical Activity Recall (PDPAR; ...
By understanding the role that lactate plays in exercise metabolism, the exercise physiologist can use the information from lactate threshold tests to predict proper racing and training paces, and assess the fitness of a subject or the efficacy of the training program. The relationship between lactate threshold and the rate of consumption of carbohydrate stores, and correlations between lactate threshold and maximal sustainable work rate, make lactate threshold a good predictor of endurance ...
Although many of the factors affecting the expression of muscular strength cannot be controlled by the fitness professional interested in assessing muscular strength, many can. Therefore, before selecting a specific test of muscular strength, the fitness professional must consider several issues including the specificity of the test, the warm-up protocol, and the timing and order of muscular strength tests. From the preceding discussion of the mechanical and physiological factors affecting ...
Two primary tests to examine maximal upper extremity anaerobic capacity and power are the Upper Body Wingate Anaerobic Test and the Medicine Ball Put. Similar to the traditional WAnT for the lower body, the Upper Body Wingate Anaerobic Test is generally performed in a laboratory setting and has the advantage of providing several outcomes related to upper body anaerobic capacity. The field test most frequently used to measure power of the upper body is the seated medicine ball put (Clemons, ...
Three tests, the balance error scoring system (BESS), the star excursion balance test (SEBT), and the modified Bass test, were selected for detailed discussion here because they represent different categories (postural steadiness, reach, and postural stability) and require minimal specialized equipment. The six positions of the balance error scoring system test are depicted in figure 12.3. A balance error occurs if the subject takes the hands off the hips or if the nontesting leg touches ...
The Science of Strength and Conditioning Series was developed with the expertise of the National Strength and Conditioning Association (NSCA). The Science of Strength and Conditioning Series, developed with the expertise of the National Strength and Conditioning Association (NSCA), is a series of texts that provide the guidelines for converting scientific research into practical application. NSCA’s Guide to Tests and Assessments offers strength and conditioning professionals a one-stop ...
