Participant Characteristics for a Mental Fatigue Intervention Study

Participant Characteristics is a dataset from a randomized crossover study comparing the efficacy of acute aerobic exercise, caffeine, and a placebo in mitigating mental fatigue. The study involved 26 adult caffeine consumers, with data collected by author Ali Shirzad and last updated on figshare in April 2026. The dataset is stored in an XLS file sized at 5.5 KB.

Use Cases

• Analyzing baseline participant characteristics for a mental fatigue study based on the described cohort of 26 adult caffeine consumers.
• Comparing demographic or physiological profiles across intervention groups (exercise, caffeine, placebo) based on the described randomized crossover design.
• Investigating potential covariates for mental fatigue outcomes based on the objective and subjective measures mentioned in the study description.

Strengths

• Dataset is openly licensed under CC-BY-4.0, permitting broad reuse.
• Study design is clearly described as a randomized crossover with 26 participants and three treatment conditions.
• Data collection involved both objective (Psychomotor Vigilance Task) and subjective (visual analog scales) measures of mental fatigue.

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 5.5 KB, indicating limited scope and likely a summary or subset of the full study data.
