NHL Combine Fitness Test Primer

Although a select few of the bike tests at the NHL Combine began on Friday, Saturday, the combine's final day, is when almost every prospect will perform all of their fitness tests.
Coming on the heels of five days of mostly interviews at the combine, here is a rundown of what fitness tests NHL prospects will be participating in.
Wingate
An aerobic test where players are put on a stationary bike (with resistance), and have 30 seconds to pedal as fast as they can. (See below)

VO2
A second bike test, the VO2 can carry on for several minutes. Although the further along a player progresses, the more resistance is added to the bike.
The player continues to ride the bike until they cannot maintain a required rpm. (See below)

Pull Ups
Pretty self-explanatory, players perform as many pull ups as they can while maintaining the proper form.

Pro Agility Test
Players' multi-directional speed and agility are measured by their performance of 5-10-5 shuttles.
Bench Press
Like the pull up test, the bench press isn't too complicated of a concept.
More important to note is that the weight players are asked to lift is dependent on their body weight, as follows.

Standing Long Jump
Players jump as far as they can from a standstill, although with permission to swing their arms for assistance.
The distance from the jumping line to the heel mark of where they land is measured to the nearest centimeter.

Wingspan and Height
Both are measured, with wingspan being recorded to the nearest .2 centimeter from middle fingertip to middle fingertip.
Grip Strength
After adjusting a hand grip dynamometer to their hand sizes, the players extend their arm and squeeze the dynamometer as hard as they can. Separate scores are recorded for each hand.
Y-Balance
Players must maintain a single-leg stance on one leg while reaching as far as possible with the contralateral leg.
They do right/left Anterior reaches, right/left Posteromedial reaches and right/left Posterolateral reaches.
Each test is performed three times, although only the best score for each is recorded.
The purpose of this test is to measure balance.

Functional Movement Screen
Players must participate in seven movement tests: hurdle step, in-line lunge, shoulder mobility, deep squats, trunk stability push-ups, rotary stability and the active straight leg raise.
These are all measure for the purpose of determining if the players have any left or right side imbalances.
It must be noted that a significant reason left and right side imbalances are checked is because it has been determined that players with imbalances are much more susceptible to injuries.
