The relationship between external training load and session rating of perceived exertion (s-RPE) training load and the impact that playing experience, playing position and 2-km time-trial performance had on s-RPE training load were explored. From 39 Australian Football players, 6.9 ± 4.6 training sessions were analysed, resulting in 270 samples. Microtechnology devices provided external training load (distance, average speed, high-speed running distance, player load (PL) and player loadslow (PLslow)). The external training load measures had moderate to very large associations (r, 95% CI) with s-RPE training load, average speed (0.45, 0.35–0.54), high-speed running distance (0.51, 0.42–0.59), PLslow (0.80, 0.75–0.84), PL (0.86, 0.83–0.89) and distance (0.88, 0.85–0.90). Differences were described using effect sizes (d ±95% CL). When controlling for external training load, the 4- to 5-year players had higher s-RPE training load than the 0- to 1- (0.44 ± 0.33) and 2- to 3-year players (0.51 ± 0.30), ruckmen had moderately higher s-RPE training load than midfielders (0.82 ± 0.58), and there was a 0.2% increase in s-RPE training load per 1 s increase in time-trial (95% CI: 0.07–0.34). Experience, position and time-trial performance impacted the relationship between external training load and s-RPE training load. This suggests that a given external training load may result in different internal responses between athletes, potentially leaving individuals at risk of overtraining or failing to elicit positive adaptation. It is therefore vital that coaches and trainers give consideration to these mediators of s-RPE training load. 相似文献

Lack of clarity about assessment criteria and standards is a source of anxiety for many first-year university students. The Developing Understanding of Assessment for Learning (DUAL) programme was designed as a staged approach to gradually familiarise students with expectations, and to provide opportunities for the development of the skills required to successfully complete assessment tasks. This paper investigated the students’ perceptions of the first two components of the DUAL programme, which assist first-year biology students to engage with stated assessment criteria and standards in order to develop their capacity to make judgements about scientific report exemplars, their peers’ scientific reports and ultimately their own. The study found strong evidence (96% of responses) that the marking and discussion of exemplar reports with peers and demonstrators clarified expectations of scientific report writing. A key feature of this element of DUAL was the opportunity for structured discussion about assessment criteria and standards between peers and markers (demonstrators). During these discussions, students can clarify explicit statements and develop a tacit knowledge base to enhance their ability to judge the quality of others’ work and their own. The peer review exercise (the second element of DUAL) was not rated as highly, with 65% of students finding the process helpful for improving their report. The negative reactions by a sizeable minority of students highlight the need to clearly communicate the expectations and benefits of peer review, with a focus on how the process of giving feedback to peers might benefit a student as much as receiving feedback on their own report. 相似文献

This study examined how Hispanic students’ academic self-concept influences the independent variables of family academic expectations, peer relationships, schoolwork, and student–teacher relationships. A survey was administered to 222 ninth-grade students in Long Island, New York, 99 of whom self-identified as Hispanic. A structural equation model analyzed the influence of the independent variables on the dependent variable, academic self-concept. A multiple regression analysis indicated that peer relationships, family academic expectations, and schoolwork were significant predictors of students’ academic self-concept. Peer relationships was a modifying variable on students’ academic self-concept. 相似文献

The purpose of this study was to investigate the effect of a congested international tournament match schedule on adductor strength and pain in elite youth football players. Twenty-two male players (age: 15.53 ± 0.48 years, height: 174.87 ± 7.59 cm, weight: 67.45 ± 7.40 kg) were included. The 5-second adductor squeeze strength was captured daily using a hand-held dynamometer during a 7-game international tournament. Pain during the squeeze test was recorded using numerical pain ratings (0–10) to quantify groin pain. Sessional rate of perceived exertion (sRPE) was collected during the tournament. Adductor strength changed significantly during the tournament in relation to time (F(14,294.94) = 1.89, p = 0.027) and cumulative sRPE (F(1,314) = 5.59, p = 0.019). Cumulative sRPE displayed a negative relationship with strength (B = ?0.008, SE = 0.0032, 95%CI = ?0.014,-0.002). The results indicate that for every 100 match sRPE arbitrary units the squeeze peak force reduced by 0.8N. Sixteen (72.7%) players demonstrated clinically meaningful strength reductions (>15%) during the tournament. Match congestion impacts on hip adductor squeeze strength in male youth football players. A negative relationship between match sRPE and adductor strength exists. Player monitoring involving the 5-second adductor squeeze test can be captured effectively and is suitable to include as part of secondary injury prevention during or immediately after a congested tournament. 相似文献
