This article is the fourth of a continuing series that examines pertinent and recent tactical strength and conditioning research reviews.

This excerpt briefly describes the different energy systems used by structural and wildland firefighters.

This article discusses flexible programming strategies for wildland fire suppression aids (FSAs). It also includes a detailed index of exercises that could be utilized for this specific population.

The following article provides a list of tests that could comprise a fitness assessment to measure overall fitness and health prior to, during, and after an academy training program.

Supplements that claim to boost nitric oxide have not been proven to be all that effective since the actual conversion in the blood cell is rather complicated and requires oxygen, which is usually in short supply during exercise or at high altitude. So how does an athlete boost their nitric oxide production?

Ankle injuries are very common and their incidence potentially can be reduced or prevented if the person has a better sense of foot position if proper footwear is worn while exercising.

Physical assessments have evolved as a result of developments in scientific research, equipment loads, operational environments, and doctrine.

In the final part of this four-part series on proper movement, the author recommends that the US Marine Corps screen the movement quality of each Marine and educate them on how to move correctly in order to reduce the risk of injury.

Get to know Army Lieutenant Colonel Nick Barringer, Program Director for the United States Army-Baylor University Master’s in Nutrition. Barringer shares how he originally planned to become a strength and conditioning coach before a nutrition course inspired him to pursue dietetics. However, it was his Certified Strength and Conditioning Specialist® (CSCS®) credential that ultimately landed him his role as the first 75th Ranger Regiment (Army Rangers) Dietitian. He recounts drawing inspiration from the Navy SEALS to start the Ranger Athlete Warrior (RAW) program and seeing the Special Operations THOR3 program follow suit — laying the groundwork for the US Army Holistic Health and Fitness (H2F) system. Barringer and McMahon discuss the synergy between strength and conditioning coaches and dietitians, as well as cultural challenges and diverse training ages in tactical settings. The pair also stress the importance of sales and building relationships before discussing basic nutrition advice and pathways into tactical and dietetics careers.
