An athlete is performing 40-meter sprints for speed development. What is the appropriate work:rest ratio?

1:12-20. Speed development requires full recovery of the phosphagen (ATP-PC) system. A work:rest ratio of 1:12-20 allows complete phosphagen recovery, ensuring each rep is performed at maximum velocity. Shorter rest would compromise speed quality.

Which plyometric exercise classification requires the highest level of prerequisite strength (1.5x bodyweight squat)?

Depth jumps. Depth jumps (dropping from a height and immediately jumping) are classified as high-intensity plyometrics. They require adequate eccentric strength to absorb landing forces. NSCA recommends a 1.5x bodyweight squat as a prerequisite for advanced plyometrics like depth jumps.

A soccer player needs to improve their ability to repeat high-intensity sprints throughout a 90-minute match. Which work:rest ratio is MOST appropriate for their conditioning program?

1:1-3. Soccer involves repeated sprints with incomplete recovery, stressing both the glycolytic and oxidative systems. A 1:1-3 work:rest ratio trains the ability to recover during active periods while maintaining repeated sprint quality, matching game demands.

When progressing an athlete through agility training, what is the correct progression from least to most advanced?

Closed drills, semi-open drills, reactive/open drills. Agility training should progress from closed (predictable, predetermined) drills to semi-open (some variability) drills to open/reactive (sport-specific, decision-making) drills. This progression ensures motor pattern mastery before adding reactive components.

Quick Answer: Speed training requires full recovery (1:12-20 work:rest ratio) with short distances (10-60m). Agility progresses from closed to open drills. Conditioning work:rest ratios match sport energy systems: 1:12-20 for phosphagen, 1:3-5 for glycolytic, 1:1 or less for oxidative.
