Using the information from question #1 in order to achieve the minimum recommendation of the 2008 Physical Activity Guidelines for Americans how many additional MET minutes of physical activity will this individual need to complete within the week.

• 300

• 500

• 110

• 250

Answer explanation

The Physical Activity Guidelines for Americans requires 500-1000 MET minutes per week

Based on absolute intensity which of the following activities is classified as vigorous physical activity

• riding a bicycle at an average speed of 8.0

• aerobic step class using a 4 inch step

• resistance training including multiple exercises at 10-15 repetitions

• walking at an average speed of 3.5 mph at 7 percent grade

Answer explanation

According to the Compendium, it has the highest MET

Performing 6 x 400 meter sprints on an Olympic size track with 45 seconds of active recovery between sprints provides the training stimulus to increase the participants anaerobic threshold. Which principle of training is represented by this scenario?

• progression

• specificity

• variation

• recovery

Answer explanation

The training in the question provides training to work on cardiovascular endurance by alternating sprint and rest. The training result is specific to the training provided

Which of the following training approaches is most likely to improve muscular strength?

• resistance training with a workload of 90 percent of 1 Rm for 5 repetitions per set

• repeated plyometric

• resistance training with a workload of 75 percent 1 RM for 15 reps per set

• push ups performed to volitional fatigue including 3 sets of 20-25 reps

Answer explanation

Anything that is repeated multiple times will increase endurance.

Pushups will increase endurance

The higher percent of RM the heavier the weight is going to be so lifting at 90 percent of your RM will increase strength

In comparison to the physical activity levels self reported on questionnaires and obtained through surveys the objective measurements of physical activity from accelerometer data are

• slightly higher

• about the same

• significantly lower

• inaccurate
