Abstract

secondary prevention

athlete monitoring

hamstring strain injury

Objectives: To evaluate strength and flexibility measures pre- and post- Australian Football (AF) competition to determine their potential utility as secondary prevention measures. Design: Cohort study. Setting: Semi-professional AF club. Participants: Ten male AF athletes (mean ± SD; age, 21.3 ± 2.2 years; height, 186.1 ± 6.3 cm; weight, 83.5 ± 8.6 kg). Main Outcome Measures: Maximal unilateral isometric knee flexion strength performed in 45 degrees of hip flexion and 30 degrees of knee flexion, flexibility measures of hip and knee extension and ankle dorsiflexion. All outcome measures were evaluated pre-match to determine baseline measurements and repeated acutely post-match and at 26, 50 and 74 h following. Comparisons were made between baseline measures and all other time points. Results: Knee flexion strength was significantly reduced at a group level acutely (-122.8N, 95%CI -156.2 to -89.4, p = 0.000) and at 26 h (-89.6N, 95%CI -122.9 to -56.2, p = 0.000) following competition. Hamstring flexibility was significantly reduced at all time periods following competition (all p < 0.05), however these values were not clinically meaningful. Conclusions: Knowledge that unilateral isometric knee flexion strength returns to pre-competition levels by 50 h following match-play in AF athletes is valuable for planning recovery time frames and may inform implementation of secondary prevention strategies.
