Power and Speed Assessment / 爆发与速度测试

Definition

Power and speed assessment is the episode’s treatment of the two fastest adaptations: power, defined as speed multiplied by force, is measured with a standing broad jump, while pure speed is treated as unnecessary to test for most people outside high-performance sport.

Current Synthesis

The broad jump is deliberately simple. It is performed from a standing position with no running approach, and the measurement runs from the start line to the furthest point back where the back heel lands. A basic benchmark is jumping your own height, a target that ratchets down about 15% for females, with elite reference points far higher, such as six-foot NFL players jumping nine to 11 feet.

Galpin’s stated point is to spot red flags rather than to optimize this particular test, which is what makes it a screening item: the jump is free, quick, and non-fatiguing, so it sits early in the day during testing weeks. Pure speed matters mainly for high-performance athletes, where a 40-yard dash or a velocity transducer on a barbell can be used, so the assessment layer keeps speed optional and power universal.

Key Claims

• Power is defined as speed multiplied by force and is measured with a standing broad jump rather than a sprint.
• The broad-jump benchmark is jumping your own height, with about a 15% reduction for females and much higher elite reference points.
• The purpose is red-flag screening rather than optimizing jump performance.
• Because the jump is free, quick, and non-fatiguing, it is well suited to the early part of a testing day.
• Pure speed testing is mainly for high-performance athletes, where a 40-yard dash or a barbell velocity transducer can be used.

Evidence

• Power definition: Essentials: How to Assess & Improve All Aspects of Your Fitness | Dr. Andy Galpin defines power as speed multiplied by force and describes it as one of the nine adaptations.
• Broad-jump protocol: Essentials: How to Assess & Improve All Aspects of Your Fitness | Dr. Andy Galpin specifies a standing broad jump with no running approach, measured from the start line to the furthest point back where the back heel lands.
• Benchmark: Essentials: How to Assess & Improve All Aspects of Your Fitness | Dr. Andy Galpin gives jumping your own height as a basic benchmark, about 15% lower for females, and six-foot NFL players jumping nine to 11 feet as an elite reference point.
• Screening purpose: Essentials: How to Assess & Improve All Aspects of Your Fitness | Dr. Andy Galpin says the point is to spot red flags rather than optimize this test.
• Speed relevance: Essentials: How to Assess & Improve All Aspects of Your Fitness | Dr. Andy Galpin says pure speed generally is not necessary to test for most people and matters mainly for high-performance athletes, where a 40-yard dash or a velocity transducer can be used.

Counterevidence & Qualifications

Broad-jump distance depends on height, limb length, body mass, landing skill, and technique, so the jump-your-height benchmark is a rough screen rather than a norm, and the episode itself frames it as a red-flag check rather than a performance target. Landing from a maximal jump also loads ankles, knees, and hips, so it is inappropriate for people with unresolved joint pain, recent injury, or balance problems without appropriate progression.

What Changed

• Added power and speed as an early, non-fatiguing assessment item and kept pure speed testing optional outside high-performance sport.
