Female Neuromuscular Performance Under Caffeine and Circadian Conditions

Experimental data from a study of 13 healthy female subjects investigating the effects of caffeine ingestion on morning neuromuscular performance. The dataset includes outcomes such as peak force, time to exhaustion, electromyography readings, and perceived exertion across three controlled trials. Author Akshay Singh published the data on figshare under a CC-BY-4.0 license, last updated in May 2026.

Use Cases

• Analyzing the effect of caffeine on peak force and time to exhaustion based on the described pre- and post-fatigue MVIC trials.
• Comparing neuromuscular performance metrics like RMS amplitude and MDF frequency across morning and evening placebo conditions.
• Modeling the relationship between rate of perceived exertion and physiological measures like torque and tympanic temperature.
• Investigating central vs. peripheral mechanisms of caffeine's effects based on the described changes in RMS and MDF.

Strengths

• Data originates from a controlled, within-subject, repeated-measures experimental design with 13 participants.
• Includes multiple physiological and perceptual measures: torque, peak force, surface EMG (RMS, MDF), time to exhaustion, RPE, and temperature.
• Results show statistically significant differences (p<0.05, p<0.01) for key outcomes like peak force and time to exhaustion.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 9.5 KB, indicating limited scope.
