Which of the following is a possible adaptation to eccentric-based training that distinguishes it from concentric training?

Increased motor unit fatigue and shorter muscle fascicle length

Enhanced coordination of motor units and increased distal muscle cross-sectional area

Reduced force production capacity due to lower mechanical loading

Which of the following best explains why eccentric muscle actions are more metabolically efficient than concentric or isometric contractions?

Eccentric contractions involve more motor units, reducing ATP demand and increasing mechanical advantage

Eccentric contractions rely solely on elastic recoil mechanisms, bypassing cross-bridge cycling and metabolic cost

A greater number of attached cross-bridges and passive tension from structural proteins, such as titin, reduce energy expenditure during force production

Two mechanisms have been proposed to explain the functional and training-induced outcomes following eccentric training. Which of the following is not one of the proposed mechanisms?

Greater capacity to produce force

Increased electromyographic activity (e.g., muscle activation)

Lower metabolic cost

Which myofilament plays a significant role during eccentric muscle actions by increasing the rigidity of the sarcomere?

Myosin

Titin

Actin-myosin interaction

Which of the following elicits the greatest improvements in muscle strength, power, and stretch-shortening cycle function?

Long-term eccentric training

Long-term concentric-only training

Traditional resistance training

As identified in this research article, who likely benefits the most from accentuated eccentric loading (AEL)?

Advanced resistance-trained individuals (e.g., strong)

Novice resistance-trained individuals

Untrained individuals
