Received December 25, 2016; Accepted January 23, 2017; Published January 30, 2017 Abstract An attempt was taken to assess the “effect of different time of day of coordinative ability of Inter-University Level Female Football Players”. For achieving the purpose of the study; two component of coordinative ability was selected Balance ability and Rhythm Ability; data was collected on 30 male soccer players age ranged from 18 to 25 years, from the Department of Physical Education and Sports Technology, Sri Guru Granth Sahib World University, Fatehgarh Sahib. To assess the balance ability of recruited subjects, Long Nose balance test and to check Rhythm Ability Sprint at the given Rhythm Test was used. The subjects were tested at different time of day i.e. one time in morning between 7.00 AM to 9.00 AM and one time in evening between3.00 PM to 5.00 PM. To compare Balance and Rhythm ability between morning and evening time soccer Inter- University level female players mean, standard deviation and paired t–test were employed with the help of statistical package of SPSS. To test the hypothesis the significance level was set at 0.05 percent. The result showed that there was no significant difference exists between mean of balance ability and Rhythm ability of Football female players at different time of day (Morning and Evening) Key Words: Time of Day, balance ability, Rhythm ability. 1. Introduction The game Soccer may take place at various times throughout the day whilst training may be held in the morning or afternoon. Despite its popularity as a sport, few scientific studies have focused on the circadian variation in soccer player's performance. For instance, some investigators, who are interested in soccer performance, reported that aerobic (Chtourou et al. 2012) anaerobic performances (Chtourou et al. 2012, Hamouda et al. 2012) and repeated sprint ability (Chtourou et al. 2012) fluctuate with time of day. Indeed peak and mean power during maximal cycling test (Chtourou et al. 2012, Hamouda et al. 2012, Aloui et al. 2012) maximal voluntary contraction (Aloui et al. 2012) Flexibility (Reilly et al. 2007) hand-grip strength (Reilly et al. 2007) total work during the repeated sprint ability test (Chtourou et al. 2012) total distance and maximal aerobic velocity during the Yo-Yo test (Chtourou et al. 2012) were significantly higher in the evening than in the morning. Most of studies showed that peak soccer performances have been found to occur in the early evening corresponding to the peak of the body temperature rhythm. Furthermore worst performance has been found in the morning (Aloui et al. 2012, Reilly et al.2007, Bernard et al. 1998, Melhim et al. 1993). Circadian rhythm in exercise performance for soccer players with morning lows and evening peaks are common findings in many laboratory tests performed on cycle ergo-meter (Chtourou et al. 2010, 2012, Hamouda et al. 2012, Aloui et al. 2012). Diurnal variation was also described in some football-specific tests, including dribbling time and chip test performance, being more accurate in the evening (Reilly et al., 2004).Reilly et al. (2007) indicated that adult football players perform at an optimum between 16:00 and 20:00 h not only for football-specific skills but also for some physical performances. Reilly et al. (2004, 2007) investigated the diurnal variation of skill measures only in adult subjects. In this context, various chronobiological studies suggest that the temporal order of children differs from that of adults (Huguet et al., 1995). To our knowledge, there is no study available in soccer has been paid to diurnal variation in skill measures, particularly those specifically related to a particular game in boys. Consequently, the aim of the present study was to assess the effects of time-of-day in some specific skills performance during field testing in boy’s footballer.
