Physical exercise preserves bone mass. Measurements of bone biomarkers may reflect the events in bone during exercise. Fifteen healthy, well-trained individuals (7 men and 8 women) performed a running test for 21 min until exhaustion. Venous blood samples were drawn before and 30 min after the exercise to measure the levels of osteocalcin, the carboxyterminal propeptide of type I procollagen (PICP) and the carboxyterminal cross-linked telopeptide of type I collagen (ICTP). After exercise, the women had a marked increase in serum osteocalcin concentrations (from 7.5±5.0 μg/1 to 11.5±3.0 μg/1), whereas the level was unaffected in the men (from 14.5±3.0 μg/1 to 13.5±4.6 μg/l). In the men there was a marked increase in PICP (from 240±47 μg/1 to 268±56 μg/1) that was not seen in the women (from 244±70 μg/1 to 253±60 μg/1). In neither group did ICTP levels change. In conclusion, significant responses were seen in PICP and osteocalcin during exercise, indicating that such measurements may be valuable for the further delineation of the effects of physical activity on bone. Furthermore, the different responses in men and women point to interesting areas for future studies.
Specialized ganglionic sympathetic neurons that release hormones into the bloodstream are found within the adrenal glands.

What is adrenal gland?</h3>
- A little gland that produces noradrenaline, adrenaline, and steroid hormones.
- These hormones assist in maintaining healthy blood pressure, heart rate, and other vital bodily functions.
- Immune system, blood pressure, stress response, metabolism, and other critical processes are all controlled by hormones that are produced by adrenal glands.
- The cortex and the medulla, the two components that make up an adrenal gland, are each in charge of manufacturing a separate hormone.
- Problems with one, both, or other glands, such as the pituitary gland, can result in diseases of the adrenal glands.
- When the adrenal glands create either an excessive amount of hormones or an excessive amount of hormones from external sources, several diseases may arise.
- Since the adrenal glands are essential for human survival, if both are destroyed, the patient will need to take drugs and hormone supplements.

The heat of fusion of the ice is the amount of energy that is required in order to melt one gram of ice. In this item, in order to solve for the heat of fusion, we simply have to divide the given energy by the mass.
heat of fusion = 16650 J / 50 g = 333 J/g
Thus, the heat of fusion of the ice is 333 J/g.
