Coffee consumption prior to physical activity may support endurance performance, reduce perceived exertion, and attenuate muscle pain, particularly during prolonged or demanding exercise and under conditions of sleep restriction or circadian misalignment.

This narrative review suggests that coffee intake before exercise can enhance endurance performance and reduce perceived exertion and muscle pain, especially in prolonged or demanding exercise contexts and when sleep is restricted or circadian rhythm is disrupted. However, effects on muscle strength and power are less consistent, and individual responses vary due to genetics, habitual intake, and circadian timing.

Grzelczyk J, Ziętala J, Budryn G, Konieczny M, Domaszewski P · Nutrients (2026)

Participants: N/A
Duration: N/A
Intervention: Coffee consumption prior to physical activity
Outcome: Endurance performance, perceived exertion, muscle pain, muscle strength, power performance
Effect Size: N/A
Population: Physically active individuals and athletes

Result: This narrative review suggests that coffee intake before exercise can enhance endurance performance and reduce perceived exertion and muscle pain, especially in prolonged or demanding exercise contexts and when sleep is restricted or circadian rhythm is disrupted. However, effects on muscle strength and power are less consistent, and individual responses vary due to genetics, habitual intake, and circadian timing.

Mechanism Graph

Caffeine blocks adenosine receptors, reducing perceived effort and fatigue.
↓
Caffeine may enhance neural drive and reduce pain perception during exercise.
↓
Coffee's bioactive compounds (non-caffeine) may modulate but not directly enhance performance.
↓
Result: Improved endurance performance and reduced perceived exertion and muscle pain in certain conditions.

Limitations

  • ⚠Narrative review, not systematic, so conclusions are qualitative and may be subject to selection bias.
  • ⚠Effects on strength and power are inconsistent and context-dependent, limiting generalizability.
  • ⚠Evidence for non-caffeine compounds is indirect and limited.

Frequently Asked Questions

Does coffee improve endurance performance?▼

Yes, evidence suggests coffee consumed before exercise can support endurance performance, especially during prolonged or demanding exercise, and under conditions of sleep restriction or circadian misalignment.

Does coffee help reduce muscle pain during exercise?▼

Yes, coffee intake may attenuate muscle pain during prolonged or demanding exercise, likely due to caffeine's effects on pain perception.

Is coffee effective for strength and power performance?▼

Effects on muscle strength and power are less consistent and appear more context-dependent, so coffee may not be universally effective for these outcomes.

Why do responses to coffee vary among individuals?▼

Individual differences in caffeine metabolism, sensitivity to stimulation, and susceptibility to sleep disruption influence both effectiveness and tolerability, along with circadian rhythm and habitual intake.
