Physical demands of training and competition in collegiate netball players

We investigated the physical demands of netball match play and different training activities. Eight collegiate netball players participated in the study. Heart rate (HR), rating of perceived exertion (RPE), and accelerometer player load (PL) data were collected in 4 matches and 15 training sessions. Training sessions were classified as skills, game-based, traditional conditioning, or repeated high-intensity effort training. Accelerometer data were collected in 3 planes and were normalized to match play/training time (PL per minute, forward per minute, sideward per minute, and vertical per minute). Centers had a higher PL per minute than all other positions (effect size; ES = 0.67-0.91), including higher accelerations in the forward (ES = 0.82-0.92), sideward (ES = 0.61-0.93), and vertical (ES = 0.74-0.93) planes. No significant differences (p > 0.05) were found between positions for RPE and peak HR. Skills training had a similar PL to match play. However, the mean HR of skills training was significantly lower than match play and all other modes of training (ES = 0.77-0.88). Peak HR for skills training (186 ± 10 b · min-1) and traditional conditioning (196 ± 8 b · min-1) was similar to match play (193 ± 9 b · min-1). There were no meaningful differences in RPE between match play and all modes of training. The center position produces greater physical demands during match play. The movement demands of netball match play are best replicated by skills training, whereas traditional conditioning best replicates the HR demands of match play. Other training modes may require modification to meet the physical demands of match play
