Abstract
Objectives
The aim of this study was to investigate potential moderators (i.e. lower body strength,
repeated-sprint ability [RSA] and maximal velocity) of injury risk within a team-sport
cohort.
Design
Observational cohort study.
Methods
Forty male amateur hurling players (age: 26.2 ± 4.4 year, height: 184.2 ± 7.1 cm, mass: 82.6 ± 4.7 kg) were recruited. During a two-year period, workload (session RPE × duration), injury and physical qualities were assessed. Specific physical qualities
assessed were a three-repetition maximum Trapbar deadlift, 6 × 35-m repeated-sprint (RSA) and 5-, 10- and 20-m sprint time. All derived workload
and physical quality measures were modelled against injury data using regression analysis.
Odds ratios (OR) were reported against a reference group.
Results
Moderate weekly loads between ≥1400 AU and ≤1900 AU were protective against injury
during both the pre-season (OR: 0.44, 95% CI: 0.18–0.66) and in-season periods (OR:
0.59, 95% CI: 0.37–0.82) compared to a low load reference group (≤1200 AU). When strength
was considered as a moderator of injury risk, stronger athletes were better able to
tolerate the given workload at a reduced risk. Stronger athletes were also better
able to tolerate larger week-to-week changes (>550–1000 AU) in workload than weaker
athletes (OR = 2.54–4.52). Athletes who were slower over 5-m (OR: 3.11, 95% CI: 2.33–3.87), 10-m
(OR: 3.45, 95% CI: 2.11–4.13) and 20-m (OR: 3.12, 95% CI: 2.11–4.13) were at increased
risk of injury compared to faster athletes. When repeated-sprint total time (RSAt) was considered as a moderator of injury risk at a given workload (≥1750 AU), athletes
with better RSAt were at reduced risk compared to those with poor RSAt (OR: 5.55, 95%: 3.98–7.94).
Conclusions
These findings demonstrate that well-developed lower-body strength, RSA and speed
are associated with better tolerance to higher workloads and reduced risk of injury
in team-sport athletes.
