Question

Is the blue color either - fast fibers or slow fibers

What about the same with orange and green color - fast or slow

this sample was most likely from a(n) ______________________ . A). couch potato B). elite runner C). extreme-distance runner

Therefore, chicken breats are enriched in pale _________ fibers. A). fast aerobic B) fast anaerobic

The thigh muscle appears redder, because thigh muscle fibers are aerobic in nature and contain more _________ than breast muscle fibers. A) myoglobin B) actin C) hemoglobin D) myosin

Human skeletal muscle tissue is composed of heterogeneous bundles of muscle fibers, grouped into three types: slow fibers, fast aerobic fibers, and fast anaerobic fibers. These three cell types differ in terms of oxygen consumption, fatigue resistance, and contraction power The proportion of each of these fiber types can vary greatly between individuals, due to both genetic predisposition and environmental influences such as exercise (or lack thereof). The following graph describes differences in muscle composition among two different types of runners and inactive persons The three different colors represent the proportion of each of the three types of muscle fibers found in each category of individual exercise habits. For each category, the blue bar is shown on the left and the green and/or orange bar is shown on the right. Compare the proportion of each type of fiber in order to complete the following key Average percent of total muscle 100 90 80 70 60 50 40 30 20 10 Hint: Among these three types of individuals, the muscles of elite sprinters contract the most rapidly and with the most force Key (Fiber Type) Fast fibers and Slow fibers Couch distance runner potato Elite sprinter Extreme-

Explanation / Answer

Blue colur are slow type muscle fibre becuse slow fibre re present in long marathon runnerthey are resistnt to fatiggue with moderate glycolyic capacity.

Orange and green colour fibre are type of Fast muscle fibres present in sprint runner.

sample was most likely from a(n) ELITE RUNNER

Therefore, chicken breats are enriched in pale FAST anaerobic fibers.

The thigh muscle appears redder, because thigh muscle fibers are aerobic in nature and contain more MYOGLOBIN than breast muscle fibers.
