Abstract
The aim of the study was to investigate the differences between chronotypes of university students (n = 19) during morning and evening physical performance parameters: reaction time (RT), tapping frequency (TF) and jump abilities (JA). The results did not show differences between a chronotype's morning vs. evening performance (RT: F-(2.16) = 0.279, p > 0.05, eta(2) = 0.03 vs.
F-(2.16) = 0.255, p > 0.05, eta(2) = 0.03; TF: F-(2.16) = 0.869, p > 0.05, eta(2) = 0.10 vs. F-(2.16) = 0.402, p > 0.05, eta(2) = 0.05; SJ: F-(2.16) = 0.136, p > 0.05, eta(2) = 0.02 vs.
F-(2.16) = 0.022, p > 0.05, eta(2) = 0.002 and CMJ: F-(2.16) = 0.068, p > 0.05, eta(2) = 0.01 vs. F-(2.16) = 0.051, p > 0.05, eta(2) = 0.01).
There were no differences (p > 0.05) between groups of chronotypes from the point of view of diurnal performance. It follows that it will not be important when our examined group-young people (university students) will realize the physical activity (concerning mainly RT, TF and JA) from the point of view of time of day (despite of different chronotypes).
