Sažetak
The aim of this study was to assess the metabolic cost (Cr) with marathon shoes (Adidas Adizero 3 [AA]) vs. track spikes (Nike Zoom Matumbo 3 [NZM]) on track. For this, five experienced runners were randomly assessed (NZM/AA) on a running track at 73% and 85% of best performance speed on 1500-m race. At first, speed (4.39 +/- 0.53 m center dot s(-1)), Crs with AA and NZM resulted 3.63 +/- 0.29 and 3.64 +/- 0.43 J center dot kg(-1)center dot m(-1) (+0.3% with NZM, effect size [ES] small and p = 0.951), respectively. Besides, at second speed (5.20 +/- 0.18 m center dot s(-1)), Crs were 4.09 +/- 0.28 and 4.07 +/- 0.22 J center dot kg(-1)center dot m(-1) (-0.5% with NZM, ES small and p = 0.919) with AA and NZM, respectively. It resulted in an increased Cr (+12.2%) between s1 and s2 with both shoe conditions (ES large and p = 0.009 and 0.011 with AA and NZM, respectively). There is a pattern yet to be confirmed for track spikes to become more beneficial at higher speeds (when duty factor becomes lower and therefore grip on track is crucial).
