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.

QUESTION

Given that the average distance of each leg is 170.5 km in distance, and sometimes undulating in elevation, you understand that fatigue is inevitable. The energy depletion model of fatigue focuses around the concept that depleted substrates are just one source of fatigue, particularly observed in muscle glycogen and phosphocreatine stores.

A. As an aerobic event, why do you expect depletion in glycogen and phosphocreatine?

B. Why, specifically, is it crucial to replenish muscle glycogen stores prior to the next leg?

QUESTION:

During a casual chat with a sport scientist from another team, they suggest preparing “finish bottles” for the longer legs of the race. Along with a dose of painkillers, a “finish bottle” typically contains an ergogenic dose of caffeine (i.e., approximately 3 to 5 mg·kg^-1 of bodyweight).

A. As a sympathetic nervous system stimulant, what acute physiological changes will likely occur following caffeine ingestion at these doses?

B. Additionally, caffeine has a mild effect at mobilising free fatty acids. Please describe what is meant by mobilisation, and how this may influence performance.

QUESTION:

You recommend that Vinnie performs altitude training as part of his preparation for the race, a training approach that is novel to him.

1. What physiological changes would you expect in the short (i.e., acute), and long-term (i.e., chronic)?
2. How will the physiological changes influence performance in the short (i.e., acute), and long-term (i.e., chronic)?
3. What parameters would you specify to achieve these benefits, and why?

Describe the hormonal changes that occur during the Ovarian and Endometrial Cycle

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?

Synapse function prompt:

You are talking with your 10 year old nephew who is very excited to tell you that he learned in science class that the nervous system is like a series of electrical wires that run throughout the body. With your newfound experience in physiology you know that’s not quite true, and that there are gaps (synapses) between neurons, meaning information in the nervous system is not just transmitted via action potential. Describe to your nephew how information is passed from the pre-synaptic to post-synaptic neuron in order to allow information flow throughout the nervous system.
