Introduction:

Knowledge about the demands of competition is necessary to aid the design and application of competition-specific training strategies.

Classification-specific requirements vary considerably during competition and there is an increased importance of peak speed and high-intensity activities for successful performance, especially in offensive players. The specific requirements across player classifications and positional roles have important implications for adopting a more individualized approach to the prescription of training.

Speed profiles derived during competition performance can be used to enhance the specificity of training. Previous studies have not compared the demands of training in relation to the demands of competition to determine the effectiveness of current training regimens.

Study aim: To investigate the speed profiles of individual training modes and compare them with competition across player classifications.

Methods:

• Speed profiles of 15 international WCR players were determined using a radio-frequency-based indoor tracking system.
• Mean and peak speed (m/s), work:rest ratios, and the relative time spent in (%), and number, of high-speed activities, performed were measured across training sessions (n = 464) and international competition (n = 34).
• Training was classified into 1 of 4 modes: conditioning (n = 71), skill-based (n = 133), game-related (n = 151), and game-simulation drills (n = 109).
• Players were grouped by their International Wheelchair Rugby Federation classification as either low-point (≤1.5; n = 8) or high-point players (≥2.0; n = 7).

Main findings:

• Conditioning drills were shown to exceed the demands of competition, irrespective of classification (P ≤ .005).
• Skill-based and game-related drills underrepresented the speed profiles of competition (P ≤ .005).
• Mean speed and work:rest ratios were significantly lower during 3- and 8-min game-simulation drills in relation to competition (P ≤ .039).
• No significant differences were identified between the 10-min running clock and competition.
• Although game-simulation drills provided the closest representation of competition, the structured duration appeared important since the 10-min running clock increased training specificity.
• Coaches can modify the desired training response by making subtle changes to the format of game-simulation drills.
