  Running
  Running is a recurring change of support from one foot to the other.
  This change begins as the runner’s center of mass falls forward of the support foot that
  the runner then pulls from the ground.
  The foot is pulled up toward the hip by the hamstring muscles while the opposite foot
  moves to the ground to provide a new support.
  As the pulled leg passes the support leg, the body reaches a new position from where
  it can continue acceleration.
  RUNNING MEASUREMENT
  7-21. Measurement of this standard using readily available video feedback does not take much time. The
  H2F performance team can quickly analyze a Soldier’s running stride to show the Soldier his or her deviation
  from the standard. This visual and verbal feedback, like any coaching, increases the Soldier’s perception of
  how he or she is running. Leaders can prescribe drills and exercises for the Soldier based on specific
  deviations from the standard. Such drills and exercises reduce excess strain on the body and increase running
  speed and distance (see figure 7-5).
  Figure 7-5. The anatomy of a running stride
  7-22. Running Drills may be performed collectively or individually. Table 7-4 summarizes Running Drills
  used to develop running skill. ATP 7-22.02 discusses and illustrates the purpose and execution of all seven
  Running Drills in detail. Soldiers perform the drills at least once per week to develop proper form. As with
  all physical training exercises, consistent adherence to precise execution provides optimal results.
  7-23. After conducting a block of instruction, commanders who want to progress running skills should
  schedule Running Drills two times per week for fifteen to twenty minutes during endurance activities.
  Running Drills should precede or follow running activities. Running Drill 1 is used to increase awareness of
  improper running form. Leaders do not have to use Running Drills in order. They may be prescribed to
  address individual and unit deficits in running skill.
  7-24. The Soldier’s perception of any movement—whether it be running, weightlifting, or shooting—is
  developed through physical repetition and attention to form. Repetition improves skill by connecting the
  brain to the body part. By asking questions about perception, performance experts, MFTs, and unit leaders
  promote faster adoption of improved skill.
