bouts of resistance exercise can lead to considerable neuromuscular fatigue lasting up to 72 hours. 3 This is particularly problematic for rugby league players during the competitive season because excessive fatigue may impair match performance. 4 Therefore, it is important to carefully regulate

The purpose of the present study was to explore the use of imagery by an elite rugby union football player and to examine the effects of an imagery intervention in a practical performance environment. The study took place over a 14-week period of the competitive season. Data collection comprised semi-structured interviews, diaries, and the Sport Imagery Questionnaire. The findings suggested that the participant primarily used cognitive specific and cognitive general imagery. Post-intervention, the participant reported greater clarity; detail; control over his anxiety, activation, and motivation levels; an improvement in his ability to generate confidence in his playing ability prior to games; and more structure to his imagery use. The study highlighted the importance of individualizing imagery interventions to meet the specific needs of different athletes.

Changes in strength over the course of a swim season could predispose the shoulder to strength imbalances and lead to injury.
To examine isometric shoulder internal- (IR) and external-rotator (ER) strength in high school swimmers over a 12-week competitive season.
Three 3 × 2 × 2 ANOVAs with repeated measures were used to determine significant main effects for IR, ER, and IR:ER strength ratio.
27 (14 female, 13 male) high school varsity swimmers.
Main Outcome Measures:
IR and ER strength during preseason, midseason, and postseason.
Significant increases in IR strength in both groups were revealed for all test sessions. ER strength significantly improved in both males and females from preseason to midseason and from preseason to postseason. IR:ER ratio revealed a significant increase from preseason to postseason.
Increases in IR strength without equal gains in ER strength were revealed and could contribute to future shoulder pathologies in competitive swimmers

This study assessed the effect of time spent in several race sectors (S) on finishing time and determined the variance in distribution of skating time and in total race time for official 1000-m sprint races conducted during a competitive season.
Total race and sector times for the first 200 m (S1) and the following two 400-m laps (S2 and S3) of 34 female and 31 male elite speed skaters performed during a series of World Cup Meetings were analyzed.
Overall, skaters started fast, reached their peak in S2, and slowed down in S3, irrespective of race category considered (eg, rank of athlete, number of race, altitude of rink, starting lane). Regression analyses revealed that spending a shorter fraction of time in the last (women in S3: B = 239.1; P < .0001; men in S3: B = 201.5; P < .0001) but not in the first (women in S1: B = -313.1; P < .0001; men in S1: B = -345.6; P < .0001) race sector is associated with a short total race time. Upper- compared with lower-ranked skaters varied less in competition-to-competition sector and total race times (women: 0.02 to 0.33 vs 0.02 to 0.51; men: 0.01 to 0.15 vs 0.02 to 0.57).
This study confirmed that skaters adopted a fast start pacing strategy during official 1000-m sprint races. However, analyses indicate that shortening time in the closing but not in the starting sector is beneficial for finishing fast. In addition, findings suggest that lower-ranked skaters should concentrate training on lowering their competition-to-competition variability in sector times.

The aim of the current study was to facilitate systematic reflection and action to improve the performance environment of a soccer team during a competitive season. Using the Performance Environment Survey (PES; Pain & Harwood, 2007) as a diagnostic instrument, the researcher worked with the coach to collaboratively identify areas in which team preparation and functioning could be improved. Completed by the players and coach after each match, the PES captured feedback around team preparation and performance in the physical, psychological, coaching, social, planning/organizational and environmental domains. Analysis of this feedback provided the stimulus for weekly discussions with the coach. Results suggested that coach and player reflection increased during the study, and the coach reported that the PES data and his reflections on that data were beneficial to managing the performance environment. In areas where change was targeted—in particular the social and the phaysical domains—improvements in team functioning were reported. Team feedback meetings were also perceived as helpful to improving player ownership and cohesiveness.

Grounded in the 2 × 2 achievement goal framework (Elliot & McGregor, 2001), the purpose of this study was to investigate the temporal relationships between achievement goals, competition appraisals and indices of psychological and emotional welfare among elite adolescent soccer players. A subsidiary aim was to ascertain the mediational role of competition appraisals in explaining the potential achievement goal and well-/ill-being relationships. Ninety-one boys (mean age = 13.82 years) involved in an elite soccer program completed multisection questionnaires capturing the targeted variables. Measures were obtained on five occasions across two competitive seasons. Multilevel regression analyses revealed that MAp goals positively, and MAv goals negatively, predicted within-person changes in well-being over two seasons. PAp goal adoption was positively associated to within-person changes in negative affect. PAv goals corresponded negatively to between-person mean differences in positive affect. The results of the indirect effects showed challenge appraisals accounted for within-person associations between a MAp goal focus and well- and ill-being over time. The present findings provide only partial support for the utility of the 2 × 2 achievement goal framework in predicting young athletes’ psychological and emotional functioning in an elite youth sport setting.
