The current world trotter record is 68.0 s/km, close to the estimates of the record limit reported in literature: 68.2 s/km for males and 69.1 s/km for females in Swedish trotters. The estimated limit has been improved on and the record limit was, therefore, investigated in the Italian trotter using the same methodology applied to the Swedish trotter. The best racing times of 30,587 Italian trotters (3-5 years old) recorded between January 1st 1992 and October 31st 2009 have been log transformed to check for trends and asymptotic limit. A positive trend was detected and limits of 61.8 s/km and 62.8 s/km have been estimated for males and females, respectively. The Generalized Extreme Value theory, applied to the 3-year old winners of the Italian Trot Derby, estimates a limit of 64.7 s/km. These results indicate that the limit for racing speed is still far from actual values.

Abstract
The current world trotter record is 68.0 s/km, close to the estimates of the record limit reported in literature: 68.2 s/km for males and 69.1 s/km for females in Swedish trotters. The estimated limit has been improved on and the record limit was, therefore, investigated in the Italian trotter using the same methodology applied to the Swedish trotter. The best racing times of 30,587 Italian trotters (3-5 years old) recorded between January 1st 1992 and October 31st 2009 have been log transformed to check for trends and asymptotic limit. A positive trend was detected and limits of 61.8 s/km and 62.8 s/km have been estimated for males and females, respectively. The Generalized Extreme Value theory, applied to the 3-year old winners of the Italian Trot Derby, estimates a limit of 64.7 s/km. These results indicate that the limit for racing speed is still far from actual values.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
