When does the influence of maturation on anthropometric and physical fitness characteristics increase and subside? (2018)
Journal Article
Towlson, C., Cobley, S., Parkin, G., & Lovell, R. (2018). When does the influence of maturation on anthropometric and physical fitness characteristics increase and subside?. Scandinavian Journal of Medicine and Science in Sports, 28(8), 1946-1955. https://doi.org/10.1111/sms.13198

The relationships between maturation and anthropometric and physical performance characteristics are dynamic and often asynchronous; confounding the capability to accurately evaluate performance during adolescence. This study aimed to (i) examine the... Read More about When does the influence of maturation on anthropometric and physical fitness characteristics increase and subside?.

Bio-banding in soccer: past, present, and future (2022)
Journal Article
Towlson, C., & Cumming, S. P. (in press). Bio-banding in soccer: past, present, and future. Annals of Human Biology, https://doi.org/10.1080/03014460.2022.2129091

Maturity-related selection biases are engrained within professional academy soccer programmes. The process of grouping of children by biological maturity (“bio-banding”), rather than age is not new. However, practice of bio-banding is becoming incre... Read More about Bio-banding in soccer: past, present, and future.

Does Transforming Subjective Measures of Load Better Represent Training and Match-Play Intensity in Youth Soccer Players? (2022)
Journal Article
Maughan, P. C., MacFarlane, N. G., Towlson, C., Barrett, S., & Swinton, P. A. (in press). Does Transforming Subjective Measures of Load Better Represent Training and Match-Play Intensity in Youth Soccer Players?. International journal of sports science & coaching, https://doi.org/10.1177/17479541221114739

The purpose of this study was to investigate the structure of relationships between measures of training load and assess whether these can be modified through non-linear transformations. Ratings of perceived exertion (RPE) and seven external load mea...
