Analysis of session-RPE and profile of mood states during a triathlon training camp.

AIM: The aim of the present study was to monitor the internal training load and profile of mood states (POMS) during a training camp in junior-elite triathletes. METHODS: Sixteen (10 male and 6 female) young triathlon athletes (junior-elite: 18±1 yrs) were included in this study. All triathletes had been training for 7±3 years, and regularly trained 4 times a week 3h per session, throughout the year. The training camp (5 days) included two daily supervised training sessions. The CR-10RPE scale was used 30 minutes after every training session to evaluate session-RPE. POMS was administered 3 times during the training camp: at the beginning, on the 3rd day, and at the end of training camp. RESULTS: Session-RPE throughout the different training days showed significant differences (P<0.001). POMS scores showed a significant increase (P<0.001) in fatigue from the first (7.8±1.4), to the third (10.5±2.2) and to the last day of training (14.2±3.4). At the end of the camp, lower (P<0.01) vigour values (12.7±2.8) emerged with respect to the first day (15.8±3.0), whereas anger decreased (P=0.015) the last day (8.6±2.2) with respect to the intermediate evaluation (9.6±2.7). CONCLUSION: The 45% increase in fatigue, the 24% decrease in vigour, and the intraindividual variability in session RPE that emerged, indicates that young triathletes need to be monitored closely during training camps in order to individualize training to avoid training maladaptation such as non-functional overreaching.

Does the junior IAAF athletic world championship represent a springboard for the success in the throwing events? A retrospective study.

AIM: The aim of the present study was to analyze how many finalists of the IAAF World Junior Championships (WJC) in the throwing events were present in the senior IAAF ranking at the end of 2012. METHODS: The results of the 8 male and the 8 female finalists of all throwing events of the last 5 editions of the WJC from the 2002 edition were gathered. We analyzed how many athletes were missing from the IAAF ranking in 2012. For those athletes that did not drop out we monitored their progression in performance comparing their WJC and their 2012 performance. Moreover, we evaluated if the relative age effects (RAE) influenced drop out rate. RESULTS: Drop out rate was 58% in 2002, 59% in 2004, 39% in 2006, and 28% in 2008 and in 2010. The female javelin throwers showed the highest drop out rate (100%) in 2002, while the female hammer throwers showed the lowest drop out rate (0%) in 2008. Performance decreased for all male shot putters, discus and hammer throwers (P<0.001). For females and for male javelin throwers, performance increased (P<0.001). RAEs showed no significant influence on drop out rate CONCLUSION: Even if 8 of the finalists won a medal at the Olympic Games or at the World Championships, it is still not clear if participation at the WJC is a prerequisite to success at a senior level, given the elevated drop out rate observed in the present study.
