Effects of Linear Periodization Training on Performance Gains and Injury Prevention in a Garrisoned Military Unit

Area of Science:

• Exercise Physiology
• Military Performance Optimization
• Sports Science

Background:

• Peak physical condition is crucial for military combat effectiveness.
• Current military fitness guidelines lack standardized, prescriptive training programs.
• This deficiency may compromise performance and increase injury risk.

Purpose of the Study:

• To evaluate the feasibility of a pilot combat conditioning program.
• The program was based on the principles of linear periodization.
• To assess its impact on fitness and injury rates in US Marines.

Main Methods:

• An 11-week supervised conditioning program was implemented for 29 US Marine Corps service members.
• Assessments included military-specific fitness tests and a maximal exercise test at baseline and post-program.
• Training and injury logs were meticulously maintained throughout the study.

Main Results:

• Program completion rate was approximately 80% (23/29 participants).
• Significant improvements were observed in cardiorespiratory fitness (Peak VO2), upper-body strength (pull-ups), and core strength (crunches).
• A low injury rate (1.3 per 100 person-months) was reported, with only one participant requiring medical attention.

Conclusions:

• A protocolized linear periodization training program is feasible for military personnel.
• The program effectively enhanced key fitness components in garrisoned Marines.
• This structured training approach demonstrates potential benefits for other military units.
