1Which muscle fiber type has the highest oxidative capacity and is most resistant to fatigue?

A.Type I (Slow-twitch)

B.Type IIa (Fast-twitch oxidative)

C.Type IIx (Fast-twitch glycolytic)

D.Type IIb (Fast-twitch)

Explanation: Type I (slow-twitch) muscle fibers have the highest oxidative capacity due to high mitochondrial density and capillary supply, making them most resistant to fatigue. These fibers are essential for tactical athletes performing prolonged operations.

2What is the primary energy system used during a 50-yard sprint?

A.ATP-PCr system

B.Glycolytic system

C.Oxidative system

D.Lipid oxidation

Explanation: The ATP-PCr (phosphagen) system provides immediate energy for high-intensity activities lasting up to about 10 seconds. A 50-yard sprint relies predominantly on this system due to its short duration and maximal intensity.

3Which hormone is primarily responsible for protein synthesis and muscle growth?

A.Testosterone

B.Cortisol

C.Insulin

D.Epinephrine

Explanation: Testosterone is the primary anabolic hormone responsible for stimulating protein synthesis and promoting muscle growth. It plays a crucial role in the adaptation to resistance training for tactical athletes.

4What is the primary plane of motion for a lateral lunge?

A.Frontal plane

B.Sagittal plane

C.Transverse plane

D.Horizontal plane

Explanation: The frontal (coronal) plane divides the body into front and back halves. A lateral lunge involves movement in this plane as the athlete moves side to side, which is important for multi-directional movement capabilities.

5Which cardiovascular adaptation occurs with chronic aerobic training?

A.Increased stroke volume

B.Decreased cardiac output

C.Increased resting heart rate

D.Decreased capillary density

Explanation: Chronic aerobic training increases stroke volume (amount of blood pumped per heartbeat), which allows the heart to pump more blood with fewer beats, resulting in a lower resting heart rate and improved cardiovascular efficiency.

6What is the primary function of the golgi tendon organ?

A.Prevent muscle injury from excessive tension

B.Initiate stretch reflex

C.Monitor muscle length

D.Control heart rate

Explanation: The golgi tendon organ (GTO) senses tension in the muscle tendon and, when activated by excessive force, inhibits muscle contraction to prevent injury. This protective mechanism is crucial during maximal strength efforts.

7During the first 10 seconds of maximal effort exercise, what percentage of ATP is supplied by the phosphagen system?

A.Approximately 70-80%

B.Approximately 40-50%

C.Approximately 90-100%

D.Approximately 20-30%

Explanation: During the first 10 seconds of maximal effort, approximately 90-100% of ATP is supplied by the phosphagen (ATP-PCr) system. This system is essential for explosive movements like sprinting and jumping required in tactical operations.

8Which biomechanical principle states that force production is directly proportional to the cross-sectional area of the muscle?

A.Force-velocity relationship

B.Length-tension relationship

C.Cross-bridge theory

D.Size principle

Explanation: The cross-bridge theory explains that force production is proportional to the number of actin-myosin cross-bridges formed, which correlates with muscle cross-sectional area. Larger muscles can generate more force, explaining why hypertrophy training increases strength.

9What is the recommended training intensity for developing maximal strength in tactical athletes?

A.85-100% of 1RM

B.67-85% of 1RM

C.50-67% of 1RM

D.30-50% of 1RM

Explanation: Maximal strength development requires training at 85-100% of 1RM with lower repetitions (1-5) and longer rest periods. This intensity recruits high-threshold motor units necessary for strength adaptations.

10Which of the following best describes the length-tension relationship in muscle physiology?

A.Maximum tension is generated at resting length

B.Maximum tension occurs at full stretch

C.Maximum tension occurs at full contraction

D.Tension is constant at all lengths

Explanation: The length-tension relationship states that maximum tension is generated when the muscle is at or near its resting length, where optimal overlap of actin and myosin filaments allows for maximum cross-bridge formation.

About the TSAC-F Exam

The TSAC-F certification is designed for strength and conditioning professionals working with tactical populations including military personnel, law enforcement officers, firefighters, and other first responders. The exam covers exercise science, exercise technique, program design, assessment/evaluation, wellness interventions, organization/administration, and nutrition specific to tactical athletes' unique occupational demands.

Frequently Asked Questions

What is the TSAC-F exam format?

The TSAC-F exam consists of 150 multiple-choice questions (130 scored + 20 unscored) administered via computer at Pearson VUE testing centers. Candidates have 3 hours to complete the exam. The exam uses scaled scoring with a passing standard of approximately 70%.

What is the TSAC-F pass rate?

Based on 2025 NSCA data, the first-time pass rate for TSAC-F is approximately 77%. The exam covers 7 content domains, with Program Design (21%) being the largest section. Proper preparation focusing on tactical-specific programming is key to success.

What are the TSAC-F eligibility requirements?

To sit for the TSAC-F exam, you must: (1) be at least 18 years old, (2) have a high school diploma or equivalent, and (3) hold current CPR/AED certification from an NSCA-approved provider. No bachelor's degree is required (unlike CSCS).

How is TSAC-F different from CSCS?

TSAC-F focuses specifically on tactical populations (military, law enforcement, fire/rescue) and their unique occupational demands. CSCS focuses on sport performance with athletes. TSAC-F requires a high school diploma; CSCS requires a bachelor's degree. TSAC-F covers wellness interventions and organization/administration not emphasized in CSCS.

What careers does TSAC-F support?

TSAC-F certified professionals work as strength and conditioning coaches for military units, police departments, fire departments, federal agencies (FBI, DEA, Border Patrol), correctional facilities, and private tactical training facilities. Positions include Tactical Strength Coach, PT Leader, and Fitness Coordinator with salaries ranging from $45,000-$85,000+.
