Changes in Physical Fitness and Program Utilization During Professional Military Education

Area of Science:

• Exercise Physiology
• Military Health
• Performance Science

Background:

• Professional Military Education (PME) programs impose significant time constraints on service members.
• These demands may compromise participants' ability to maintain optimal physical readiness.
• This study investigates fitness changes during PME and the role of support programs.

Purpose of the Study:

• To examine physical fitness changes throughout a 10-month PME academic cycle.
• To assess adherence to and impact of optional Tailored Performance Plans (TPP).
• To identify behavioral and environmental factors influencing physical fitness outcomes.

Main Methods:

• 238 participants underwent fitness assessments pre- and post-PME.
• Optional TPPs offered 1-on-1 consultations and fitness support.
• Demographic and survey data were collected via self-report.

Main Results:

• Significant increases in body fat percentage and flexibility were observed.
• Declines were noted in fat-free mass index, explosive power (vertical jump), and aerobic capacity (VO2max).
• TPP participation did not significantly alter overall fitness trends, though it maintained grip strength.

Conclusions:

• PME participants experienced mixed fitness changes: improved flexibility and core endurance, but reduced muscle mass and aerobic fitness.
• Tailored Performance Plans (TPP) demonstrated limited impact on broad fitness domains.
• TPP engagement may preserve specific neuromuscular outcomes like grip strength but does not confer widespread performance benefits.
