The RAMP Protocol: What the Research Actually Says About Structuring a Warm-Up

By Muhammad Dzulhisham · MSc Sports Coaching, NSCA-CSCS

Ask a coach to defend the exercises, sets, and rest periods that make up the main session, and most can talk for twenty minutes. Ask the same coach to defend the ten minutes before it — the jog, the stretches, whatever drill happened to be next on the whiteboard — and the answer is usually some version of "it gets them ready." That gap in scrutiny matters more than it looks. A 2010 systematic review with meta-analysis pooling 32 studies on warming up found that a warm-up improved subsequent performance in 79% of the criterion measures tested across sprinting, jumping, and strength outcomes¹ — a real, repeatedly measured effect sitting underneath a part of a session that gets a fraction of the design attention spent on everything that follows it.

The most widely adopted answer to "what should actually be in there" is a coaching framework called RAMP — Raise, Activate, Mobilize, Potentiate — developed by strength and conditioning coach Ian Jeffreys and first published in 2007.² It is not a single fixed routine; it is a structure, four physiological jobs a warm-up needs to do in sequence, each building on the one before it. A follow-up 2017 paper made the case that RAMP is "more than simply short-term preparation," and the framework has since become standard reference material for the UK Strength and Conditioning Association and NSCA educational resources.³ Whether that structure actually beats an unstructured warm-up, and what belongs in each of its four phases, is now a question with controlled-trial data behind it, not just coaching intuition.

Why "raise the temperature" is the literal first job, not a metaphor

The oldest and best-established mechanism behind warming up is thermal, not psychological. David Bishop's two-part 2003 review in Sports Medicine split warm-up mechanisms into two categories: temperature-related effects — reduced muscle and joint viscosity, faster nerve conduction velocity, an altered force-velocity relationship, greater anaerobic energy availability — and non-temperature-related effects, including elevated baseline oxygen uptake and post-activation potentiation.^4,5 The temperature effects are the larger and more consistently documented of the two, and they are also old news in exercise physiology: a foundational 1979 study by Bergh and Ekblom found that maximal power output, jump height, and sprint performance all moved with muscle temperature at roughly 4–6% per degree Celsius, while maximal isometric strength moved at a smaller but still real ~2% per degree.⁶ That is not a rounding effect. A muscle a few degrees cooler than it could be is producing meaningfully less force before a single rep of the actual session has started.

This is what the Raise phase of RAMP is for, and it is also why "raise" is deliberately not a synonym for "cardio." The job is specifically to lift muscle temperature, heart rate, and blood flow to working tissue using low-to-moderate intensity, general, whole-body movement — jogging, skipping, general calisthenics — not to accumulate fatigue before the session even begins. A 2015 review in Sports Medicine by McGowan, Pyne, Thompson, and Rattray, examining active and passive warm-up strategies across sport and exercise contexts, notes a real trade-off the raise phase has to manage: active warm-up raises temperature effectively, but it also depletes some energy substrate that passive heating methods do not touch — meaning the phase has to run long enough to move temperature but stay light enough that it is not quietly spending down fuel the main session still needs.⁷ In controlled RAMP trials that report their own timing, this phase tends to be short by design: the raise segment in one recent randomized trial ran roughly three minutes of light jogging, high knees, lateral gallops, and carioca before moving on — not the fifteen-minute continuous jog still common on many fields.⁸

Activate and Mobilize: dynamic movement standing in for the muscles about to be used

The middle two letters of RAMP are often run as one continuous block in practice, and for good reason — both are about preparing the specific muscles and joints the session is about to demand, rather than the whole body generically. Activate targets muscle groups that need to be switched on, often ones prone to being under-recruited relative to more dominant synergists, like the glutes before a squat-and-sprint session. Mobilize takes the joints through the actual range of motion the sport requires, using controlled, active movement rather than passive holds. That is deliberately not the same job a static-stretching session does, and it is worth being precise about the distinction rather than treating "dynamic warm-up drills" and "flexibility training" as interchangeable — they test and train different things, a distinction this site has covered in depth elsewhere. What belongs specifically in a RAMP warm-up is dynamic: leg swings, walking lunges, hurdle-mobility drills, lateral shuffles — movement that takes a joint through range under the athlete's own muscular control, closer to what the next phase of the session will actually ask the body to do.

The evidence on dosing this phase is more specific than "a few dynamic stretches." A 2018 review in Sports Medicine by Opplert and Babault, examining the acute effects of dynamic stretching across the current literature, describes an effective dose built from short reps — roughly 10–20 seconds of movement per exercise, at a tempo in the range of 50–120 beats per minute — rather than long, sustained holds.⁹ The literature the review draws on also points to a dose-response pattern worth taking seriously in the other direction: one and two sets of dynamic stretching per muscle group produced measurable sprint-performance improvements in the underlying trials, while pushing to three sets started reversing that benefit and slowing subsequent sprint velocity.⁹ More dynamic stretching is not automatically better preparation — past a fairly modest volume, it starts behaving like the fatigue it is supposed to be preventing.

A warm-up that spends fifteen minutes raising temperature and mobilizing joints, then walks straight into the session, has done three-quarters of the job RAMP describes and skipped the part most directly tied to the first few explosive efforts.

Potentiate: the phase most warm-ups skip, and why its timing is unforgiving

Potentiate is the phase most often missing from an otherwise reasonable warm-up — the sport-specific, high-intensity work that comes right before the session or competition itself: a handful of near-maximal sprints, jumps, or lighter-but-fast loaded reps of the main lift. The intent is to prime the neuromuscular system, and the physiology behind why that works has gotten considerably more precise over the past decade. A 2019 review by Blazevich and Babault in Frontiers in Physiology draws a sharp line between two things often talked about as if they were one: classical post-activation potentiation (PAP), a measurable, electrically-evoked increase in muscle twitch force that peaks within seconds of an intense contraction and is largely gone within about five minutes, and post-activation performance enhancement (PAPE), a slower-building, longer-lasting increase in voluntary force and power that tends to emerge six to ten minutes after the triggering effort and can persist for fifteen minutes or more.¹⁰ The mechanisms behind PAPE are broader than the single calcium-sensitivity pathway that drives PAP — a small rise in muscle temperature (roughly 0.3–0.9°C from the effort itself), shifts in intracellular water, and possibly some added neural drive have all been proposed as contributors.¹⁰

The practical implication is specific: what most athletes experience as a "primed" feeling after a hard sprint or a heavy set in warm-up is almost certainly PAPE, not classical PAP — which means the useful window sits several minutes after the potentiating effort, not immediately after it. Move straight from a heavy potentiation set into the first competitive rep, and the athlete is more likely still carrying acute fatigue than riding a performance boost. Blazevich and Babault are also candid that this window shows large inter-individual variability tied to strength level, training history, and fiber-type composition — exactly why "wait precisely four minutes" is not a defensible blanket instruction. Tracking an individual athlete's own response, rather than importing someone else's fixed number, is what the evidence actually supports.¹⁰

What happens when the whole sequence is tested against alternatives

Individual-phase mechanisms are one kind of evidence. Testing the full four-phase sequence against a traditional warm-up, static stretching, or no warm-up at all is a more direct kind, and that evidence has grown substantially in the past two years. A 2025 randomized crossover trial in Frontiers in Physiology put 14 youth soccer players through three separate warm-up conditions on non-consecutive days — no warm-up, a static-stretching routine, and a full RAMP sequence lasting roughly 20 minutes (about 3 minutes raise, 10 minutes activate, 5 minutes mobilize, 2 minutes potentiate) — then tested countermovement jump height and 30-metre sprint time after each.⁸ RAMP produced a jump height of 32.49cm against 29.85cm for no warm-up and 30.26cm for static stretching (p<0.001, a large effect), and a 30m sprint time of 4.16 seconds against 4.24 seconds for no warm-up and 4.22 seconds for static stretching (p=0.009).⁸ Static stretching, notably, was not meaningfully different from doing no warm-up at all on either measure — the benefit tracked specifically with the structured RAMP sequence, not with pre-activity movement in general.

A separate 2025 crossover study of 13 elite athletes comparing RAMP against a traditional warm-up found a similar pattern: the traditional warm-up produced no significant improvement in sprint or change-of-direction performance beyond a small gain in the 10–20m sprint phase, while RAMP produced broader improvements across sprint, jump, and change-of-direction measures.¹¹ The effect is not only acute, either. A 2024 randomized trial split 50 competitive football players into a RAMP group and a traditional-warm-up control group for four weeks of training, then re-tested 30m sprint time, T-test agility, and Yo-Yo endurance — finding statistically significant gains for the RAMP group across all three measures (speed p=0.001, agility p=0.001, endurance p=0.002).¹² None of these are large trials, and all skew toward young, male, competitive-sport populations — a real limit on how far the specific numbers generalize. But three independently run studies, using three different designs and three different athlete populations, converging on the same direction of effect is considerably stronger evidence than any one of them would be alone.

The version of this argument with the largest sample size is not about performance at all

The single largest controlled trial testing a structured, RAMP-shaped warm-up was not measuring sprint times or jump height — it was measuring injuries, at a scale none of the performance trials above come close to. A 2008 cluster-randomized controlled trial published in the BMJ, led by Soligard and colleagues, assigned 125 football clubs (1,892 female players aged 13–17) to either their normal warm-up or a structured 20-minute program built from eight minutes of running-based activities, ten minutes of strength and balance work, and a closing two minutes of running — a shape that maps closely onto raise, activate/mobilize, and a lighter potentiate close.¹³ Across one full season, the structured-warm-up group had significantly fewer injuries overall (rate ratio 0.68), fewer overuse injuries (rate ratio 0.47), and fewer severe injuries (rate ratio 0.55) than the control group.¹³ That trial's warm-up program is what F-MARC and FIFA went on to roll out worldwide in 2009 as the 11+ injury-prevention program — direct evidence that sequencing a warm-up around raising temperature, activating and mobilizing the tissue about to be loaded, and finishing with something closer to game intensity is not only a performance question. Run across a season and a large enough group of athletes, it shows up in the injury column too.

Putting a session-ready protocol on paper

Pulled together, the evidence supports a warm-up built roughly like this, run in sequence, totaling somewhere in the 15–20 minute range that shows up consistently across the trials above:

• Raise (roughly 3–8 minutes): low-to-moderate intensity, general, whole-body movement — jogging, skipping, easy multidirectional drills — enough to genuinely lift muscle temperature and heart rate without spending down the energy the session still needs.
• Activate and Mobilize (roughly 8–12 minutes): dynamic, sport-specific drills targeting the muscles and joints the session will load — short reps of about 10–20 seconds each, one to two sets per exercise, not long static holds and not excessive volume that starts working against the sprint and power output it is meant to protect.
• Potentiate (roughly 2–5 minutes): a small number of high-intensity, sport-specific efforts — short sprints, jumps, or fast, lighter-loaded reps of the session's main pattern — placed close to, but not at, the very start of the working session, since the useful window is more likely several minutes wide than immediate.
• Individualize the timing where it matters most. The gap between the potentiate phase and the first competitive rep is exactly where the research is least willing to hand over one fixed number — track what actually works for a given athlete rather than importing someone else's transition time.
• Treat the whole sequence as programmed, not improvised. The comparative trials above found static stretching alone performed no better than no warm-up at all, and a traditional, unstructured warm-up underperformed RAMP on nearly every measure tested — the benefit tracks the structure, not just the act of moving beforehand.

None of this makes the warm-up the most interesting fifteen minutes of a session, and it does not need to be. What the evidence above argues for is treating it with the same design discipline as the sets and reps that follow it — a sequence with a specific physiological job in each phase, dosed and timed on purpose, rather than whatever combination of jogging and stretching happened to fill the time before the actual session began.
