IBFCSM CPSO key terms

The highest rate at which the body can take up and use oxygen during maximal exercise, expressed in milliliters of oxygen per kilogram per minute. It reflects combined cardiovascular, respiratory, and muscular capacity and is a core marker of aerobic fitness.

The exercise intensity at which blood lactate begins to accumulate faster than it can be cleared. It marks the transition from sustainable aerobic work toward fatigue-prone effort and is a strong predictor of endurance performance.

The oxygen cost required to move at a given submaximal speed or power output. A more economical athlete uses less energy for the same work, which often separates competitors with similar aerobic capacity.

The total amount of work that can be performed using energy systems that do not rely on oxygen, primarily the phosphagen and glycolytic pathways. It underpins short, high-intensity efforts such as sprints and repeated power actions.

How quickly an athlete can generate force after the onset of a contraction. It is measured from the slope of a force-time curve and predicts explosive actions like jumping, sprinting, and changing direction.

A prolonged decline in performance and well-being caused by an imbalance between training stress and recovery that does not resolve with a few days of rest. It requires weeks to months of reduced load and medical evaluation.

Tracking heart rate variability, resting heart rate, or orthostatic responses to gauge how an athlete is adapting to training load. Abnormal trends can flag accumulating fatigue before performance visibly declines.

The systematic collection of training load, sleep, soreness, mood, and readiness data to guide program adjustments. Good monitoring links objective and subjective measures so coaches can act before injury or underperformance occurs.

A comparison of recent training load, usually the past week, against a longer rolling average such as four weeks. Very high ratios suggest rapid load spikes that raise injury risk; very low ratios suggest detraining.

The principle of gradually increasing training stress so the body adapts without being overwhelmed. Increases in volume, intensity, or density should be planned and monitored rather than applied abruptly.

The planned sequencing of training phases with varying volume and intensity to peak for competition and reduce overuse risk. It typically cycles from general preparation toward specific, high-intensity work.

A planned period of reduced training volume or intensity, often lasting about a week, that allows recovery and consolidation of adaptations. It is a preventive tool rather than a response to injury.

Exercises that use a rapid stretch-shortening cycle, such as jumps and bounds, to improve explosive power. They require adequate strength and landing control and should be introduced progressively.

A structured program that modifies cadence, foot strike, or trunk posture to reduce loads associated with running injury. It is individualized and progressed gradually to avoid transferring stress elsewhere.

A structured assessment before sport participation that identifies medical conditions, prior injuries, and risk factors needing management. Findings guide clearance decisions and individualized conditioning plans.

Provocative physical examination maneuvers used to support or refute a suspected diagnosis, such as ligament or meniscal injury. Their value depends on pretest probability, and a single test rarely confirms a diagnosis alone.

Sensitivity is the proportion of people with a condition who test positive; specificity is the proportion without it who test negative. Together they describe how well a test rules a diagnosis in or out.

A statistic showing how much a test result changes the probability of a diagnosis. Positive and negative likelihood ratios summarize test performance and are more clinically useful than sensitivity or specificity alone.

Objective benchmarks an athlete must meet before resuming sport, covering pain, strength, range of motion, functional testing, and psychological readiness. Clear criteria reduce reinjury risk and support defensible decisions.

Staged progression from acute protection and pain control through mobility, strength, power, and sport-specific training. Progression is based on meeting criteria rather than on elapsed time alone.

Concentric actions shorten a muscle under tension; eccentric actions lengthen it while resisting force. Eccentric exercise is especially used to build tendon capacity during rehabilitation.

Progressive exercise programs, often heavy slow or eccentric, that stimulate tendon adaptation and reduce pain over weeks. They require adequate load and patient adherence rather than passive treatment alone.

Hands-on techniques such as joint mobilization and soft tissue work used to reduce pain and improve movement. It is best combined with active exercise and education rather than used in isolation.

Explaining how the nervous system and tissues produce pain in order to reduce fear and unhelpful beliefs. It supports active rehabilitation and is especially useful for persistent or recurrent problems.

A traumatic brain injury caused by a blow or force to the head or body that produces transient neurological symptoms. Any suspected case requires removal from play and assessment by a qualified clinician.

A standardized sideline and office evaluation of suspected concussion covering symptoms, cognition, balance, and neurological screening. It is repeated over time and interpreted against baseline or normative data.

Rare, catastrophic brain swelling that can occur when a second head impact happens before a prior concussion has resolved. This is why athletes with suspected concussion must not return to play that day.

An abrupt loss of heart function causing collapse and absent normal breathing. Immediate CPR and early defibrillation with an AED are the only interventions that meaningfully improve survival.

Applying an automated external defibrillator to analyze heart rhythm and deliver a shock if indicated. Pads are placed on the bare chest and the device is used as soon as available during resuscitation.

A written, rehearsed protocol assigning roles for recognizing emergencies, activating EMS, retrieving equipment, and transporting an injured athlete. It should be site-specific and practiced regularly.

A spectrum from heat cramps and exhaustion to heat stroke, driven by exercise in heat with inadequate cooling. Heat stroke with altered mental status is a medical emergency requiring rapid cooling.

Individualizing fluid intake before, during, and after exercise based on sweat rate, duration, and environment. Overdrinking can cause dangerous hyponatremia, so replacement should not simply be maximal.

The legal and quality landscape governing supplements, which in many countries is less strict than for medicines. Contamination and prohibited substances are real risks, so products should be third-party tested.

Regulations listing prohibited substances and methods, plus athlete obligations such as therapeutic use exemptions and whereabouts reporting. Strict liability means an athlete is responsible for what enters their body.

Formal approval allowing an athlete to use a otherwise prohibited medication for a legitimate medical need. It must be obtained before use through the relevant anti-doping authority.

A syndrome of impaired physiological function caused by low energy availability, affecting bone health, hormones, menstrual function, and performance. It can occur in any athlete, not only in those with low body weight.

Unhealthy eating behaviors or preoccupation with food, weight, and body shape that fall short of a formal eating disorder diagnosis but still harm health and performance. Early confidential screening and referral are essential.

Damage to bone from repetitive loading, ranging from stress reaction to complete fracture. Risk depends on load, bone quality, and energy availability, and some sites carry high complication risk.

Structuring goals to be specific, measurable, achievable, relevant, and time-bound. Process goals tend to support performance and motivation better than outcome-only goals.

A collaborative conversation style that strengthens an athlete's own reasons for change, such as adherence to rehabilitation. It uses open questions, reflective listening, and affirmation rather than persuasion.

A climate in which athletes feel safe to speak up, report symptoms, and admit mistakes without fear of punishment. It supports injury reporting, mental health disclosure, and ethical team culture.

A patient's voluntary agreement to assessment or treatment after understanding its purpose, risks, benefits, and alternatives. It is an ongoing conversation, not a single signature on a form.

The legal and professional boundaries defining what a clinician is trained and permitted to do. Working outside them risks patient harm and professional sanction, and referral is required when needs exceed them.

The duty to protect an athlete's private health information and share it only with appropriate consent or legal authority. Team staff should receive only the information needed for their role.
