The Fitness and Strength Experiment: Primary and Secondary Outcomes

The individual experiments in the Lifestyle Experiment (Sugar, Fitness, Sleep and Food) will all have shorter term, more responsive metrics called primary outcomes. Those are outcomes that are likely to change over the short (usually 3 month) period of the individual experiment. We call these "responsive" metrics because we expect that they might respond in that short period whereas other metrics, although very important to the overall experiment, they take longer to respond. Some of these longer term metrics might change in this short period but they might not. Thus, these longer term metrics will be secondary outcomes for the individual experiments.

The primary outcomes in the Fitness and Strength Experiment are as follows:

• Estimated or measured V02 Max

• Strength Measurements:

  • Grip Strength

  • Chair Stand Test

  • 1 - Rep Maximum Strength

• Muscle Mass (if available)

• Body Fat Percentage and Waist Circumference

The Secondary Outcomes in the Fitness and Strength Experiment are as follows:

• HbA1c

• Fasting Glucose

• Fasting Insulin Level

• Triglycerides

• LDL

• HDL: (important secondary outcome)

• hsCRP
