Summary
This review clarifies exercise-induced pain (EIP) by distinguishing it from other pain types. It provides updated definitions and discusses mechanisms, interventions, and future research directions for EIP in endurance exercise.
Area of Science:
- Sports Science
- Pain Research
- Exercise Physiology
Background:
- Pain is a complex sensory and emotional experience.
- Exercise-induced pain (EIP) is distinct from other pain types like delayed onset muscle soreness or chronic pain.
- Current research often conflates different pain types, potentially leading to inappropriate interventions.
Purpose of the Study:
- To provide an updated conceptual and operational definition of EIP.
- To distinguish EIP from other pain subcategories based on aetiology and characteristics.
- To discuss experimental pain models, neuro-psychophysiological mechanisms, and interventions related to EIP.
Main Methods:
- Literature review and synthesis of existing research on exercise-induced pain.
- Analysis of experimental pain models and their relevance to EIP.
- Examination of the impact of EIP on exercise behaviour and performance.
Main Results:
- EIP differs significantly from other pain types in its transient and non-threatening nature during exercise.
- Existing research may incorrectly assume parity between distinct pain types, impacting understanding of EIP mechanisms.
- Updated definitions and a focus on specific pain types are crucial for accurate research and effective interventions.
Conclusions:
- A clear distinction between EIP and other pain types is necessary for advancing research.
- Understanding the neuro-psychophysiological mechanisms of EIP is key to managing its impact on exercise.
- Further research should focus on EIP within endurance exercise settings, considering its aetiology, measurement, and manipulation.

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.
