Answer:
The correct option is d. Metabolic specificity
.
Explanation:
The specificity principle says that we must train the physical qualities (physiological elements involved) in the concrete conditions that the competition demands. Accordingly, the impact on muscles and metabolic pathways not used directly during exercise is very small. Metabolic specificity is a principle of adaptation and it applies to the energy systems mobilized during the exercise. The muscle mass involved and the overall intensity of the exercise will dictate whether the responses to training will be limited to adaptations at the muscular level or if adaptations will occur at the cardiovascular level. Continuous aerobic training of submaximal intensity is reflected in the increase in the activity of oxidative metabolism enzymes. The running speed of a marathon is regulated by aerobic metabolism in the recruited muscle fibers and by the economic conversion of this energy into speed. Increasing the distance and time of her races progressively allows the endurance athlete to exercise at a high intensity for significantly longer periods of time.
Answer:
geographical isolation
Explanation:
Reproductive isolation is a process of evolution that ensures that members of different species are incapable of mating and when they do, such mating do not result into any offspring or leads to the production of invalid offspring.
There are two mechanisms of reproductive isolation:
- Pre-zygotic mechanisms prevents fertilization between two different species and these include habitat isolation, mating seasons, mechanical isolation, gamete isolation, geographical isolation and behavioral isolation.
- Post-zygotic isolation prevents the products of fertilization from becoming valid and this include hybrid inviability, hybrid sterility and hybrid breakdown.
<em>Geographical isolation involves the existence of geographical barriers between two populations such that there cannot be mating between the two. The two populations eventually evolve to become different species.</em>
