Today we headed off to the Flagstaff Nordic Center to try cross-country skiing and fat tire biking in the snow.
With the sun shining down and the snow starting to melt, we quickly put on our cross-country skis in the yurt and headed off onto the trail.
This being my first experience cross-country skiing, it quickly became apparent why professional cross-country skiers have some of the highest VO2 maxes around. If you have ever watched competitive cross-country skiing, the athletes seem to speed over the snow effortlessly. As novices, we discovered that gliding over the snow isn’t quite so easy; the skill takes endurance, coordination, speed, and BALANCE.

Despite all of our falls, the Extreme Team had a great time cross-country skiing!

Later that afternoon, we headed back to the yurt for lunch. Afterwards, some group members went back out to continue cross-country skiing and the others headed off to try fat tire biking.
You may wonder, after a never-ending 50-mile bike ride and a treacherous mountain bike ride through sandy, cacti infested Tucson, how hard could biking through some soft powdery snow be? I think the best way to answer this question is with some up-close footage of the experience:

By 4pm, the Extreme Team was exhausted and hungry. We quickly headed to the grocery store to get ingredients for fish tacos before our guest lecturer arrived (took a selfie of course)!

The fish tacos were as great as was the company of our guest, Dr. Stan Lindstedt a professor and researcher at Northern Arizona University. After a delicious desert of Apple Pie by Blaire and Lemon Meringue Pie by Marissa, we all gathered in the living room for Stan’s lecture on Eccentric Muscle contractions.
As an Exercise Science student, I am typically learning about concentric muscle contractions, i.e. when muscles shorten while generating force. Learning more about the role of eccentric muscle contractions, i.e. controlled muscle lengthening under a load greater than the force the muscle can produce, gave a much-needed insight on the role of muscle function.
Stan pointed out that, compared to concentric muscle contractions, eccentric contractions can produce the same force at a lower workload. With high force outputs, many injuries tend to occur during eccentric muscle movements. This has lead to many healthcare practitioners viewing eccentric contractions as “bad” contractions to practice during training compared to that of concentric. Contrary to popular belief, through research, Stan and his research staff found that eccentric conditioning helps to enhance the elastic component of muscle, Titin. Thus, moderated eccentric conditioning is beneficial for performers in order to maximize their force production with a low energy cost.
Needless to say, Day 10 in Flagstaff was a big day for the Extreme Team. Looking forward to a day of skiing tomorrow.
Love,
Courtney and the Extreme Team
































SO, 30 miles later, after getting lost about five times, two flat tires (poor Courtney), a few falls and lots of hungry tummys we FINALLY made it to the diner!
It’s safe to say I’ve never seen so many sad looking college students in my life. Just when we thought we were going to starve to death and be left as food for the Arizona Bark Scorpion, Sweeney and Tara came to the rescue with granola bars and told us there was a vending machine close by! With our stomachs full of Cheez-its, Doritos, Pop Tarts, Twizzlers and any of the other healthy options the vending machine had to offer, we were back on the bikes headed home.
and the AMAZING sunset over the Catalina Mountains.








The 2015 girls had the highest VO2 max average yet, at 50.1 ml/min-kg body weight, and the boys had an average of 55.5ml/min-kg. Upon finishing our testing, we caught our breath and ate our lunches. We bade Doug goodbye until tomorrow, when we would perform the Wingate Test.
Traversing the Golden Gate Trail, we observed the various cacti and cholla: Saguaro, Teddy Bear, Prickly Pear, Barrel, and the group favorite, Jumping Cholla.
Dr. Sweeney pointed out that Native Americans use the needles on the Saguaro for sewing. The hike was beautiful. We found ourselves torn between looking up to take in the scenery and looking down to avoid tripping. The view is indescribable. The air makes you feel fresh and alive.


We pulled up a map on a phone and re-oriented ourselves. Dr. Sweeney was the Jumping Cholla’s next victim. His attack was at the leg. He, too, recovered and we began our journey back to the beginning of the Golden Gates Trail.
We hurried to catch up to the group. Arms swinging and head swiveling, I was looking everywhere and at everything. Suddenly, my left hand caught on something. I heard Blaire yell “Ohhh!” I felt a pinch and looked down to none other than the infamous Jumping Cholla sticking out of my fist.Dr. Sweeney flicked the cactus off with a stick and pulled out the remaining pieces later on at the house. And so with little blood and many pictures, I survived the Jumping Cholla.
