BACKGROUND INFORMATION:

Vinnie is a professional road cyclist participating in the 2020 Giro d’Italia, a three-week race nearly 3,600 km in distance with some stages exceeding altitudes of 2,700 m above sea level (i.e., Stelvio Pass, Italy). As the newly hired head of the high-performance team, it is your responsibility to manage his preparation for the event. You must demonstrate to your team a fundamental understanding of physiology, the chronic adaptations expected from his training, and methods that could be implemented to improve the likelihood of success.

QUESTION:

Your first job was to schedule a VO₂max test for Vinnie to examine his aerobic fitness. After repeating the assessment several weeks later after an intensive training block, you notice that VO₂max has dropped, but there has been an increase in VT₂. Please discuss why VO₂max decreased and what impact both changes will have on performance?

What is the effect of low progesterone levels in females who are trying to concieve

2.What are hormones?

3.Most hormones circulate in blood and come into contact with essentially all cells. However, a specific hormone usually affects only a limited number of cells called _____________________________which contain receptors for that hormone. When hormones bind to receptors, it triggers a cascade of reactions within the cell that affects function.4.Endocrine glands secrete hormones directly into the bloodstream while exocrine glands release secretions through ducts into cavities or body surfaces. Some endocrine glands have other functions beyond hormone production and secretion. These organs are called mixed glands, because they have both endocrine and exocrine functions. For example:In addition to hormone production, the pancreas secretes digestive enzymes into the small intestines. Consider the other endocrine glands and list glands that would be considered mixed based on the above criteria. __________________________
