Sprint kayaking is prominent in Europe with training methods devised and adopted from Eastern bloc training systems. There is a lack of published research on sprint kayaking locally and internationally. Consequently, the aims of this research directly address establishing a relationship between kayak specific training and the Profile of Mood States (POMS); monitoring training duration and intensity and establish a link with the POMS and Rating of Perceived Exertion (RPE); to monitor the general wellness of the kayakers. Seven elite sprint kayakers (two male, five female) with the following characteristics: age 26.5 (1.4) years, training experience 8.4 (3.7) years were part of the South African national sprint kayaking squad selected to participate in this study, based on their preparation for the 2008 Beijing Olympic Games (one male athlete did not qualify but continued to train). The females trained for the 500m K1, K2 and K4 events and the male for the 1000m K1. Three training camps (TC1, TC2, TC3) were held from 12 November to 09 December 2007, 25 February to 22 March 2008 and 14 July to 04 August 2008. RPE (Borg Scale) was recorded for each session. The 65-item POMS was completed twice a week, after half a days rest (Wednesday) and after a day and half rest (Sunday). Daily training load was calculated from RPE and session time; and an energy index calculated from the POMS vigour and fatigue scores. The Wisconsin Upper Respiratory Symptom Survey recorded illness and injury. Descriptive and Inferential Statistics, Friedman’s rank test for k correlated samples, The Wilcoxon Signed Ranks Test, Spearman rank-order correlations were used to analyse the data. Statistical significance was calculated at 5% (p=0.05) and 10% (p=0.1). The results showed higher vigour scores associated with lower RPE and low training load; and high RPE associated with higher anger, confusion, depression, fatigue and total mood disturbance scores. There was a relationship between increasing POMS scores and duration of the training camps. The POMS findings could not completely explain the relationship found between RPE and duration of the training camps. The energy index was higher pre-camp and the extended rest periods during the camps. The findings for the POMS and RPE suggested that a state of overreaching might have occurred during the camps. Monitoring of the kayakers for an extended period after the training camps would have been useful to determine whether any of these individuals became over-trained. In accordance with Kentta et al (2006), regular use of the POMS may help detect under recovery, preventing staleness and unwanted rest for extended periods. Future studies will enable a retrospective view on these results. / Dissertation (MA)--University of Pretoria, 2012. / Biokinetics, Sport and Leisure Sciences / unrestricted

Title: Possibilities of Non-invasive Control of Hypoxic Training Objectives: To find out whether there is a statistically significant change in mood dynamics measured by the POMS questionnaire while staying and training in a natural hypoxic environment (LHTH), compared to staying and training in normoxy. To compare and verify other non-invasive methods of controlled training in natural hypoxia. Methods: The research has the character of a quasi-experiment with a plan of repeated measurements. As a method of data acquisition, questioning was carried out using a standardized POMS questionnaire, analysis of training documentation. In the selected persons heart rate measurements and analysis of blood biochemical examination records were also done. An additional interview was included. There are two case studies. Results: A statistically significant difference in mood states was observed in the second week of the training camp, when a naturally hypoxic environment reduced the Energy Index and increased the Total Mood Disturbance of athletes. Casuistic investigations did not find any correlation between athletes' reduced performance and changes in the morning resting heart rate or biochemical blood analysis. However, a correlation between the decrease in performance and the overall mood disorder was...

Approved for public release, distribution is unlimited / This study investigates the effects of reversing sleep-wake cycles on mood, sleep, and fatigue of the crewmembers and Air Wing 9 of the USS JOHN C. STENNIS (CVN-74). It also reviews the research conducted in sleep deprivation, circadian rhythms, shiftwork, fatigue, and mood. The effects of reversing sleep-wake cycle on mood of the crewmembers were analyzed by assessing a repeated administration of the Profile of Mood States (POMS). Mood states were monitored at three time points associated with the current work schedule (night shift vs. day shift) of the crewmembers. The results showed that younger participants were angrier than older participants on night shiftwork. The results also indicated that there was a significant interaction between repeated measures of mood states and gender. In addition, female participants reported significantly higher mood scale scores than the male participants, and topside participants were getting significantly less sleep than belowdecks participants. Given these findings, this area of research warrants further exploration. There is a significant need to educate military personnel of the effects of sleep deprivation and shiftwork on their job performance and individual health and safety. / Ensign, United States Navy

En el moment en què els ballarins pateixen una lesió l'atenció dels professionals de la medicina de la dansa se centra prioritàriament en els aspectes físics del tractament i de la recuperació. Amb tot, la lesió sovint té conseqüències pel que fa a les funcions psicològiques. L'objectiu d'aquesta recerca de tipus exploratori, de disseny empíric, transversal, descriptiu i correlacional/causal és conèixer les respostes emocionals davant la lesió de ballarins lesionats de dansa mesurant depressió, desesperança, estat emocional i estratègies d'afrontament. Per això, es varen administrar el POMS, BDI-II, BHS i CHIP, a més d'un qüestionari sobre els factors associats a la lesió, a una mostra de 94 ballarins lesionats a Nova York. Els resultats més destacats assenyalen que el 31,9% dels ballarins va presentar una simptomatologia de depressió en les categories de lleu, moderat i sever en el BDI-II i un 42,9% d'ells desesperança. Quant al perfil de l'estat d'ànim (POMS), constatem una tendència a nivells elevats de tensió i confusió, seguits de depressió, fatiga i hostilitat. El vigor destaca per la seva absència. Les estratègies d'afrontament utilitzades inclouen l'afrontament instrumental i el de distracció, mentre que tendeixen a no utilitzar en la mateixa mesura estratègies pal·liatives. Pel que fa a d'altres factors associats cal destacar, en primer lloc, les preocupacions econòmiques com a factor que pot arribar a ser un impediment a l'hora d'obtenir tractament mèdic i/o psicològic. En segon lloc, en relació a les conductes dels ballarins és rellevant que el 64,8% va continuar ballant malgrat la lesió, i que el 31,9% va cuidar la lesió per sí mateix, sense cap ajut mèdic. Finalment, pel que fa al suport i l'ajuda que pot oferir un psicòleg especialitzat en dansa, els ballarins valoren positivament les tècniques de relaxació, i el seu suport davant les respostes emocionals davant les lesions, així com en la transició psicosocial de la carrera de ballarí. / En el momento en que los bailarines sufren una lesión la atención de los profesionales de la medicina de la danza se centra prioritariamente en los aspectos físicos del tratamiento y de la recuperación. Sin embargo, la lesión tiene a menudo consecuencias sobre las funciones psicológicas. El objetivo de esta investigación de tipo exploratorio, de diseño empírico, transversal, descriptivo y correlacional/causal es conocer las respuestas emocionales en bailarines lesionados midiendo depresión, desesperanza, estado emocional y estrategias de afrontamiento. Para ello, se administraron el POMS, BDI-II, BHS y CHIP, además de un cuestionario sobre los factores asociados a la lesión, a una muestra de 94 bailarines lesionados en Nueva York. Los resultados más destacados señalan que el 31,9% de los bailarines presentó una sintomatología de depresión en las categorías de leve, moderado y severo en el BDI-II y un 42,9% de ellos desesperanza. En cuanto al perfil del estado de ánimo (POMS), constatamos una tendencia a niveles elevados de tensión y confusión, seguidos de depresión, fatiga y hostilidad. El vigor destaca por su bajas puntuaciones. Las estrategias de afrontamiento empleadas incluyen el afrontamiento instrumental y el de distracción, mientras que tienden a no utilizar en la misma medida estrategias paliativas. En cuanto a otros factores asociados es importante destacar, en primer lugar, las preocupaciones económicas como factor que puede llegar ser un impedimento para obtener tratamiento médico y/o psicológico. En segundo lugar, en relación con las conductas de los bailarines cabe destacar que el 64,8% continuó bailando aún estando lesionado, y que el 31,9% cuidó la lesión por sí mismo. Finalmente, en cuanto al apoyo y la ayuda que puede ofrecer un psicólogo especializado en danza, los bailarines valoran positivamente las técnicas de relajación, y su apoyo ante las respuestas emocionales ante las lesiones, así como en la transición psicosocial después de la carrera de bailarín. / When dancers are injured dance medicine professionals focus their attention primarily on the physical aspects of treatment and recovery. However, injuries usually have an impact on the individual's psychological functions as well. The objective of this exploratory study, of experimental, transversal, descriptive and correlational/causal design, is to know the emotional responses towards injury in injured dancers measuring depression, hopelessness, emotional state and coping strategies. In order to do that, the POMS, BDI-II, BHS and CHIP were administered, together with a questionnaire regarding injury-associated factors, to a sample of 94 injured dancers in New York. As for the results, 31.9% of the dancers showed depression symptomatology in the categories mild, moderate and severe in the BDI-II and 42.9 of them showed hopelessness. Regarding the profile of mood states (POMS), results show a tendency towards high levels of tension and confusion, followed by depression, fatigue and hostility. Vigor stands out due to its low scores. The coping strategies used include instrumental and distraction, while not using palliative strategies in the same degree. Regarding other injury-associated factors it is important to note, firstly, the dancers' economical worries as a factor that can even prevent them from accessing medical and/or psychological treatment. Secondly, as regards dancers' behavior, 64.8% of them continued dancing despite being injured, and that 31.9% took care of their injuries themselves, without any professional medical help. Finally, regarding the support and help a dance psychologist can provide, dancers considered positive the relaxation techniques, and their support when emotionally responding to injuries as well as in the psychosocial transition at the end of their professional career.

Phosphatidylserine (PS) is an endogenously occurring phospholipid that has been shown to have cognition and mood enhancing properties in humans, possibly through its role as an enzyme co-factor in cellular signal transduction. Specifically, PS has been identified as activator of classical isoforms of protein kinase C, an enzyme known to be involved in the growth and differentiation of neural cells, and is therefore thought to play a role in the protection of neurons. The purpose of this study was to examine the effects of supplementation with PS and caffeine on measures of cognition, reaction time and mood prior to and following an exercise stress. Twenty, healthy, resistance trained males (17) and females (3) (mean ± SD; age: 22.75 ± 3.27 yrs; height: 177.03 ± 8.44cm; weight: 78.98 ± 11.24kg; body fat%: 14.28 ± 6.6), volunteered to participate in this randomized, double-blind, placebo-controlled study. Participants were assigned to a PS group (400mg/day PS; 100mg/day caffeine, N=9) or PL (16g/day Carbs, N=11) delivered in the form of 4 candy chews identical in size, shape and color. Subjects performed an acute bout of full body resistance exercise, prior to (T1) and following 14 days of supplementation (T2). Measures of reaction time (Dynavision® D2 Visuomotor Training Device), cognition (Serial Subtraction Test, SST), and mood (Profile of Mood States, POMS) were assessed immediately before and following resistance exercise in both T1 and T2. Data was analyzed using two-way ANCOVA and repeated measures ANOVA. Supplementation with 400mg PS and 100mg caffeine did not have a significant impact upon measures of reaction time or cognition between groups at baseline or following acute resistance exercise. However, there was a non-significant trend to the attenuation of fatigue iv between groups, following acute resistance exercise (p = 0.071). Interestingly, our data suggests that acute resistance exercise alone may improve cognitive function. Although more research is necessary regarding optimal dosage and supplementation duration, the current findings suggest that supplementation 400mg/day PS with 100mg/day caffeine may attenuate fatigue following acute resistance exercise. It is possible that the lack of significance may be the result of both an inhibition of the PS activated pathway and a withdrawal effect from caffeine.
