Aldosterone release leads to  

When you have an agent being trained with reinforcement learning, it learns a policy that maximizes the reward obtained after interacting with the environment. In the example below, the agent must reach a star, and can move in four directions (up, down, left, right). If it moves towards the edge of the environment, nothing happens, but it still counts as a movement. The reward for any movement is equal to -1 and the agent stops moving as soon as it reaches a star. This reward function makes the agent learn to minimize the number of movements that are necessary to reach one of the stars from any initial state, as can be seen in the optimal policy. Random policy Optimal policy Now, assume the reward for a horizontal movement is -1, for a vertical movement is -100, and the discount factor is 1 (no discount). What would be the optimal policy in this case? Formatting suggestion for Canvas: Create a table with the same size of the grid above, and then use the letters UDLRN to indicate the directions Up, Down, Left, Right, and None. For each table cell, add all letters for actions that are part of the optimal policy. For instance, the optimal policy above would be formatted as: N L LDR D U LUR R N U LUR UR U

From the Environmental group presentation: Wearable devices that measure hydration and core temperature may be useful for athletes to train with however they have not been ______. 

Explain the major mechanisms that are responsible for the increase in Vo2max that occurs after chronic endurance training. In your answer discuss some of the current recommendations for increasing Vo2Max and why this programming would allow for adaptations to occur. 

A professional cyclist is preparing for a stage race in a hot climate. The coach implements a heat acclimation protocol: Duration: 60 minutes/day for 10 days in a hot room Goal: Improve thermoregulation and reduce heat stress Monitoring: Heart rate, core temperature, sweat rate, and sodium concentration After 7 days, the athlete reports feeling more comfortable in the heat. Which of the following physiological changes would indicate successful heat acclimation?

When is unsupervised learning particularly useful? Provide an example of a real-world application that benefits from this type of learning.

From the Cardiovascular/Cardiorespiratory group presentation: True or false?  There are still quite a few populations that are under-represented in cardiorespiratory assessment. 

Which of the following is NOT a stimulus for aldosterone secretion during exercise?

From the Cardiovascular/Cardiorespiratory group presentation: A trend in the field is to use ______ to interpret data from wearables and clinical devices. 

An elite marathon runner is preparing for a race in a hot, humid environment. The event is scheduled in three weeks, and the athlete wants to optimize heat acclimation to improve performance and reduce heat stress. Based on current research, which of the following strategies is most effective for achieving heat acclimation?
