Key result
High cumulative exercise cardiac load linked to reduced maximum running speed in collegiate football athletes.
Why the study?
Training programs that fail to provide sufficient recovery during the in-season may impair performance, and the influence of collegiate football workload on autonomic nervous system recovery remained unclear.
Does high exercise cardiac load during in-season training reduce maximum running speed and autonomic nervous system recovery in collegiate football athletes?

Does high exercise cardiac load during in-season training reduce maximum running speed and autonomic nervous system recovery in collegiate football athletes?
Effect estimate: β = -0.15
p-value: p=<0.0000
High acute and cumulative exercise cardiac loads during in-season training are associated with reduced maximum running speed and deteriorating autonomic nervous system function in collegiate football athletes.
Renaghan et al. (2023) conducted a cohort in American Football Athletes (n=30). Exercise cardiac load (ECL) was evaluated on Maximum running speed (β = -0.15, p=<0.0000). Exposure to high cumulative exercise cardiac loads was negatively associated with maximum running speed (β = -0.15, p<0.0000) in collegiate American football athletes.
