Isometric Hamstring Force Reliability Data for 30 Collegiate Male Athletes

Individual participant data from a study assessing the between-session reliability of peak and early force-time variables in a unilateral isometric hamstring assessment. The dataset contains measurements from 30 collegiate male athletes across three repeated sessions, with data analyzed for force at 50, 100, 150, 200, 250 ms, and peak force. The dataset was authored by Adam E. Sundh, last updated on 2026-05-22, and is shared under a CC-BY-4.0 license.

Use Cases

• Analyze the reliability of early force-time variables (50-250 ms) across repeated testing sessions.
• Model the relationship between peak force and rapid force generation capacity in hamstring muscles.
• Assess the effect of session order on force output using the trivial to small effect sizes reported.
• Develop baseline metrics for tracking performance changes or fatigue in athletes using the isometric single-leg long-lever bridge protocol.

Strengths

• Dataset is focused on a specific, well-described protocol (unilateral isometric long-lever bridge) with a clear sample of 30 collegiate male athletes.
• Provides concrete reliability metrics, including ICC values ≥ 0.51 for early force and ≥ 0.74 for peak force, and CV% ≤ 12.65%.
• Data is structured for direct analysis of force at specific time points (50, 100, 150, 200, 250 ms) and peak force.

Limitations

• Row count is unknown, which may limit suitability assessment for certain statistical methods.
• Column-level documentation is absent; field semantics must be inferred after download.
• The sample is limited to 30 male collegiate athletes, which may affect generalizability to other populations.
