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:
As the event is soon approaching, parts of Hungary are experiencing a heatwave. Indeed, temperatures may exceed 32° Celsius during the first leg of the race leaving Budapest.
A. Will the ambient temperature have any impact on Vinnie’s performance?
B. In terms of thermoregulation, what physiological changes are likely to occur during this leg of the race? Explain how these changes may influence performance.
ANS: A: yes, The ambient temperature have impact on vinnie's performance.
As the experiencing of a heatwave and temperature may exceed 32 celsius during the first leg of the race.
when the race begins, vinnie's speed may fast initially because at the starting point, atmospheric temperature will not impact this much on vinnie's race.
but after some time, atmospheric temperature will effect on vinnie's body temperature. Thats why when vinnie's body internal temperature will may change.
at this temperature, vinnie's body cells can't able to proper biochemical reaction. so, vinnie's energy level slows down at some point. so, vinnie slows down at some point becasue of impact of heat wave and atmospheric temperature.
ANS:B: In terms of Thermoregulation, as we discussed in ans. ''A'', The atmospheric temperature is 32 degree celsius with heatwave and the vinnie's body temperature (Human body tempertaure) is 37 degree celsius.
so that Atmospheric temperature will affect on vinnie's internal body temperature so that energy level goes down at some point.
At the term of physiological effect on vinnie's body, vinnie feel sweat.also vinnie body cell can not able to make proper energy.
At some point vinnie can not able to take proper amount of oxygen at this much of altitude level. so, anaerobic reaction will start on his cells. In this anaerobic reaction lactic acid produce in his body. when lactic acid amount increase more that is very harmfull to human body.
lactic acid is stored in vinnie's leg. also in anaerobic reaction, ATP is not produced much. It will only 7 to 8% ATP formed. This much of low level of ATP, vinnie can not able to race fast. so, vinnie may slow down at some point.
so, These physiological changes may influence vinnie's performance.
