Training session intensity affects plasma redox status in amateur rhythmic gymnasts

Purpose:The aim of this study was to examine systemic responses of oxidant/antioxidant status following 2 training sessions of different intensity in amateur rhythmic gymnasts.Methods:Before the experimental training,10 female gymnasts performed a gradually increased exercise test to assess maximal heart rate,maximal oxygen consumption,and anaerobic threshold.They executed 2 intermittent training sessions separated by 48 h of recovery(48 h-post R):the first was performed at low-moderate intensity(LMI)and the second at high intensity(HI).Blood samples were collected immediately preand post-training and 48 h-post R.Hydroperoxide level(OxL)and total antioxidant capacity(TAC)were photometrically measured.Results:OxL was significantly higher in post-training and 48 h-post R following HI than the same conditions after an LMI session(HI vs.LMI post-training:381.10±46.17(mean±SD)vs.344.18±27.94 Units Carratelli(U.CARR);48 h-post R:412.21±26.61 vs.373.80±36.08 U.CARR).There was no change in TAC between the 2 training sessions investigated.In LMI training,OxL significantly decreased in post-training and increased to reach the baseline at 48 h-post R,whereas TAC increased only at 48 h-post R.In HI training,OxL significantly increased to reach a high oxidative stress 48 h-post R,whereas TAC was lower in post-training than pre-training.Conclusion:The pattern of OxL and TAC levels implies different regulation mechanisms by HI and LMI training sessions.High oxidative stress induced by an HI protocol might be associated with both insufficient TAC and recovery time at 48 h necessary to restore redox balance.

Youth and Employment： The Effectiveness of the Youth Guarantee Plan in Emilia Romagna and Sicily

The paper presents a comparative analysis of the ＂Youth Guarantee Plan＂ implemented by two Italian regions： Emilia Romagna and Sicily. Within the tradition of the sociology of public action, the study proposes a deepening of the institutional and cognitive analysis of public policies. From the comparison, two distinct models of public action emerge： The first model that implemented by the Emilia Romagna Region, appears more procedural and more founded on the involvement of institutions present in the territory （employment centres, universities, chambers of commerce, professional bodies）, whilst the second model, implemented by the Sicily Region, seems founded mainly on the emphasis placed on the economistic definition of the policy. From the study, most of all, the processes through which the distinct regional public actions succeed in interpreting the innovative potential of the Youth Guarantee Plan and the relations existing between the effectiveness of the policies and the collective meanings that institutions and individuals assign to them, emerge.
