The aim of the present study was to investigate the differences in energy system contributions and temporal variables between offensive and all-round playing styles. Fifteen male table tennis players (Offensive players: N = 7; All-round players: N = 8) participated in the study. Matches were monitored by a portable gas analyzer and the blood lactate responses was also measured. The contributions of the oxidative (W OXID ), phosphagen (W PCr ), and glycolytic (W [La] ) energy systems were assumed as the oxygen consumption measured during the matches above of baseline value, the fast component of excess post-exercise oxygen consumption (EPOC FAST ) measured after the matches, and the net of blood lactate concentration (Δ[La]), respectively. Energy systems contributions were not significantly different between the offensive and all-round playing styles (W OXID : 96.1±2.0 and 97.0±0.6%, P = 0.86; W PCr : 2.7±1.7 and 2.0±0.6%, P = 0.13; W [La] : 1.2±0.5 and 1.0±0.7%, P = 0.95; respectively), however, magnitude-based analysis of W PCr presented Likely higher contribution for offensive compared to all-round players. Regarding temporal variables, only rate of shots presented higher values for offensive when compared to all-round players ( P = 0.03), while the magnitude-based analysis presented Very likely lower , Likely lower and Likely higher outcomes of rate of shots, W PCr and maximal oxygen consumption, respectively, for all-round players. Strong negative correlation was verified for offensive players between number of shots and W PCr (r = -0.86, P = 0.01), while all-round players showed strong correlations between rally duration, W OXID (r = 0.76, P = 0.03) and maximal oxygen consumption (r = 0.81, P = 0.03). Therefore, despite no differences in energy system contributions for offensive and all-round players, different playing styles seems to requires specific energy systems demands.
