Scenario:

River Rosewell is a professional rower who has just been accepted into the USA athlete in residence program at the Olympic Training Center in Colorado Springs. He has been team rowing since the age of 11. He attended Harvard University on a rowing scholarship is now 21 years old. He has spent the last year after graduation (graduated with a BS degree in Business) pursuing his dream of making it on to the USA rowing team for the single skulls event (heavyweight).
The typical length of a single skulls race is 2 kilometers. He rowed a practice event at the same course he is going to open the season at and had an average (average of two race runs) of 7.01 minutes. This placed him 12th out a field of 30 international qualifiers. This was good enough to qualify him for the actual rowing event event held 12 weeks later.
Assume that the “actual” race will be carried out under very similar weather conditions.
He has worked with a personal trainer for the last year, working on improving his basic strength, strength endurance, power and mobility, and is ready for more “sport specific training” as he approaches skulling circuit.   

Listed below are some of his current anthropometric and performance based characteristics

Physical Characteristics
Height 6”2
Weight 195lb
% Body Fat 11%
1RM Back Squat 330lb
1RM Power clean 260lb
1RM Bench press 280lb
Deadlift 450lb
CMVJ height (hands on hips) 27.0 inches
Can perform 20 bodyweight pull ups
Rowing ergometer, based incremental Vo2max 59ml.kg.min

1. Highlight the key physiological (and some anthropometric) characteristics which would seem important if you wanted to be an elite rower. Please provide rationales for your choices.

2. Design the first 4 weeks (1-4) of his preparation for the rowing event concentrating upon his; Strength and Conditioning, sport specific balance and mobility. Please spell out; exercises used and why, sets, reps, rest periods and relative loads used and why. Pay close attention to the exercises you prescribe and their physiological suitability for the sport of rowing.

In pathologic conditions where the alveolar membrane is thickened there is little effect on the exchange of carbon dioxide, but oxygen diffusion is impaired. Based on your understanding of the respiratory membrane function, propose an explanation for this phenomenon.

(2pts) Why is alveolar ventilation rate a more important phyisological measure of respiratory function than total air moved into the respiratory passages?

Consider the normal path of an ovum as it leaves the ovary and enters the uterine tube.

If ovulation occurs at day 14 of a 28-day cycle, but a woman has conception on day 19 (so conception has occurred in the uterus), what do you think would be the likely series of events to follow?
Would implantation occur?
If it does, what might be the problems, or is it a normal implantation?
Can she have a "tubal" pregnancy?

There are multiple events that can initiate the release of HCl in the stomach. Two such events are the sight and smell of food. Choose the answer below that is NOT true of this particular phase of gastric acid secretion.

The motor nerves of this pathway are part of the somatic motor division.
The nerves involved are long reflexes.
This prepares the stomach for food before its arrival in the stomach.
Multiple areas of the brain are involved in processing the stimuli.
