One-Year Longitudinal Case Study of a Grassroots Football Player's Training Activities

733 hours of logged activity detail the training regimen of a 13-year-old male football player over one year, including organized team training, matches, private academy sessions, unorganized play, and other sports activities. The dataset was created by Dag Vidar Hanstad using daily logs and interviews, and was last updated on 2026-04-27. It provides a detailed, contextually grounded view of physical activity load and forms within a grassroots football environment.

Use Cases

• Analyzing the distribution of training hours between organized and unorganized football activities based on the detailed activity categorization.
• Studying the conceptual blend of deliberate play and deliberate practice in training forms based on the player's logged experiences.
• Modeling longitudinal athlete development pathways based on the one-year, hour-by-hour activity data from a single case.
• Comparing training loads and activity types in grassroots versus elite football environments based on the case study evidence.

Strengths

• 733 hours of meticulously logged activity data over a full year provides high temporal resolution.
• Data includes multiple activity categories (e.g., 196 hours team training, 110 hours private academy, 157 hours unorganized football) allowing for comparative analysis.
• Empirical material is supplemented by an in-depth player interview, adding qualitative context to the quantitative logs.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a single-case study (n=1) of one player, limiting generalizability.
