Huvudsyftet med föreliggande studie var att undersöka skillnader mellan crossfitutövare och traditionellt gymaktiva i muskelsträvan, träningsrelaterat instagram-användande, tvångsmässig passion och träningsmängd samt undersöka samband avseende dessa variabler. Vidare undersökte studien om exponering för tränings- och utseenderelaterade bilder, tvångsmässig passion samt ökat träningsbeteende efter exponering för bilder på instagram kan predicera muskelsträvan. Genom en kvantitativ forskningsansats fick deltagarna besvara en enkät innefattande mätinstrumenten: Godin Leisure- Time Exercise Questionnaire, The Passion Scale, Drive for muscularity scale. Utifrån ett bekvämlighetsurval rekryterades 156 deltagare (66 män och 89 kvinnor, en person uppgav inte kön) i åldern 16-65 år (M=28). Studien visar att crossfitutövare har mer muskelsträvan, träningsrelaterat instagram-användande, tvångsmässig passion samt träningsmängd jämfört med traditionellt gymaktiva. Muskelsträvan visade positiva samband med träningsrelaterat instagram-användande, tvångsmässig passion samt träningsmängd. Vidare visade studien att exponering för tränings- och utseenderelaterade bilder på Instagram, tvångsmässig passion samt ökat träningsbeteende efter exponering för bilder på Instagram kan predicera muskelsträvan. För framtida forskning föreslås att undersöka om andra grupper med stort träningsrelaterat instagram-användande också har mer muskelsträvan samt tvångsmässig passion.

Nesse sentido, analisou-se a produção de lactato sanguíneo, pressão arterial (PA), frequência cardíaca (FC) e percepção de esforço/dor (PSE/PSD) nos períodos pré e pós exercício, e sinal eletromiográfico (EMG) durante as séries, dos músculos Reto Femoral (RF), Vasto Lateral (VL), Vasto Medial (VM) e Bíceps Femoral (BF). Participaram do estudo 19 indivíduos do sexo masculino, sendo 10 de TR (idade = 25,40 ± 1,64 anos; percentual de gordura = 8,36 ± 2,20%; massa corporal = 78,88 ± 6,81 Kg; estatura = 176,00 ± 5,31cm; frequência semanal de treinamento = 4,50 ± 0,85 dias; tempo de treinamento = 4,90 ± 1,28 anos) e 9 de CrossFit® (idade = 27,44 ± 3,94 anos; percentual de gordura = 7,87 ± 3,71%; massa corporal = 83,37 ± 7,78; estatura = 177,00 ± 7,00m; frequência semanal de treinamento = 4,67 ± 0,50 dias; tempo de treinamento = 2,22 ± 0,44 anos). No primeiro dia, os indivíduos realizaram medidas antropométricas e teste de uma repetição máxima (1RM) (TR = 112,40 ± 17,35 kg; CrossFit® = 137,11 ± 26,89 kg). Com intervalo entre 48 a 72 horas foram realizadas duas sessões aleatórias do exercício supracitado com pressão de oclusão (60% pressão total) e os manguitos fixados na parte proximal dos membros inferiores: a) 30%1RM + RFS (4 séries 30, 15, 15, 15 repetições) b) 30%1RM (4 séries 30, 15, 15, 15 repetições), sendo coletados o lactato sanguíneo no repouso e 2 minutos após o exercício, PSE e PSD no repouso e após a sessão, PAS e FC no repouso, 5º e 10º minutos e sinal EMG durante as séries de ambos os protocolos. Foram realizados testes estatísticos de homogeneidade de variância, além dos testes t de Student para amostras independentes, avaliação de medidas repetidas para a interação grupo vs. tempo, seguida do post-hoc de Bonferroni, adotando-se o valor de significância p ≤ 0,05. Ambos os grupos aumentaram significativamente (efeito tempo; p=0.001) no protocolo (BI 30% 1RM+RFS / BI 30% 1RM) e (efeito interação; p=0.003) no protocolo (BI 30% 1RM+RFS), porém no protocolo (BI 30% 1RM), não apresentou diferença (efeito interação; p=0.904). Na PSE e PSD, os valores aumentaram significativamente do repouso para o pós-exercício (efeito tempo; p=0.001) para ambos os protocolos e não apresentou diferença significativa (efeito interação; p=0.205/p=0.180), respectivamente. O comportamento da PAS (efeito tempo; p=0.001) apresentou diferença significativa em ambos os protocolos, e não apresentando diferença significativa no protocolo (BI 30%1RM+RFS) (efeito interação; p=0.759), porém apresentou diferença significativa no protocolo (BI 30%1RM) (efeito interação; p=0.034). Em relação à FC, ambos os protocolos apresentaram diferença significativa (efeito tempo; p=0.001), e não apresentaram diferença entre grupos (efeito interação; p=0.322/p=0.502). Na ativação muscular foi encontrada diferença durante as séries (efeito tempo; p=0.001) para ambos os protocolos, e não foi encontrada diferença entre os grupos (efeito interação; p=0.320). Nossos achados indicam o que já era esperado em relação as respostas das variáveis investigadas. Em relação aos momentos pré e pós, todas apresentaram aumento dos valores, enquanto que na comparação entre grupos algumas variáveis indicam que os grupos investigados apresentam particularidades em relação ao tipo de treinamento que praticam. / The aim of the this study was to analyze the metabolical, hemodinamic, perceptive and electromyography responses of low intensity (LI) exercise with blood flow restriction (BFR) and LI (30% 1RM) in the exercise free half squat (HS) in the pre and post moments and compare them between bodybuilders and practitioners Crossfit®. For this purpose the production of blood lactate, blood pressure (BP) heart rate (HR) and perceived exertion / pain (RPE / SPP) in the pre- and post-exercise periods, and electromyography signal (EMG) of the Vastus Lateralis (VL), Biceps Femoris (BF), Rectus Femoris (RF) and Vastus Medialis (VM) muscles during the strength exercise were measured. Nineteen male individuals took part in this study, being 10 of them bodybuilders practitioners (age = 25,40 ± 1,64 years; body fat percentage = 8,36 ± 2,20%; body mass index = 78,88 ± 6,81 Kg; height = 176,00 ± 5,31cm; weekly training frequency = 4,50 ± 0,85 days; time of training = 4,90 ± 1,28 years) and 9 CrossFit® practitioners (age = 27,44 ± 3,94 years; body fat percentage = 7,87 ± 3,71%; body mass index = 83,37 ± 7,78; height = 177,00 ± 7,00cm; weekly training frequency = 4,67 ± 0,50 days; time of training = 2,22 ± 0,44 years). On the first day, the individuals were taken anthropometric measurements and one-repetition maximum strength test (1RM) in the exercise Half Squat (HS) (1RM = bodybuilders = 112,40 ± 17,35 kg; CrossFit® = 137,11 ± 26,89 kg).On the following days, two random session of the aforementioned exercise were applied with occlusion pressure (60% total pressure) and the cuffs attached to the proximal parts of the lower limbs: a) 30%1RM + BFR (4 series sets 30, 15, 15, 15 repetitions) b) 30%1RM (4 series sets 30, 15, 15, 15 repetitions), where blood lactate was collected during rest and 2 minutes after training, AP BP and HRrest during rest, 5th and 10th minutes and electromyographic signal during the series sets of both protocols. Statistical tests were conducted for homogeneity of variance, besides Student’s t-tests for independent samples, repeated measures to group vs. time interaction evaluation followed by Bonferroni post-hoc test, adopting the significance p-value p ≤ 0,05.In both groups, there was a significant increase in protocol (BI 30% 1RM + RFS / BI 30% 1RM) and (interaction effect, p = 0.003) in protocol (BI 30% 1RM + RFS). EF (BI 30% 1RM), showed no difference (interaction effect, p = 0.904). In RPE and PSD, values increased significantly from rest to post-exercise (time effect, p = 0.001) for both protocols and did not present a significant difference (interaction effect, p = 0.205 / p = 0.180), respectively. The BP behavior (time effect, p = 0.001) showed a significant difference in both protocols, and did not present a significant difference in the protocol (BI 30% 1RM + BFR) (interaction effect, p = 0.759) (BI 30% 1RM) (interaction effect, p = 0.034). In relation to HR, both protocols had a significant difference (time effect, p = 0.001), and did not present differences between groups (interaction effect, p = 0.322 / p = 0.502). In muscle activation, differences were found during the series (time effect, p = 0.001) for both protocols, and no difference was found between groups (interaction effect, p = 0.320). Our findings indicate what was expected in relation to the responses of the investigated variables. Regarding the pre and post moments, all presented increased values, whereas in the comparison between groups some variables indicate that the groups investigated have particularities in relation to the type of training they practice.

Uppsatsens syfte är att konstruera riktlinjer för en användarprofilering som motiverar till fysiskt träningsutövande, samt uppmuntra användarprofiler till att förmedla sanningsenlig träningsresultatet inom ett digitalt socialt nätverk inriktat på fysisk träning. Studien undersöker även utövares inställning till att dela med sig av sina träningsresultat. Målet är att ta fram specifika, konkreta och praktiska faktorer som skall kunna appliceras i verkliga digitala nätverk. En kvalitativ studie genomfördes genom intervjuer och observationer av en testgrupp på åtta personer med varierande träningskunskaper och bakgrund. Studien resulterade i två olika kategorier a) motivation till dokumentationstjänst i digitalt nätverk och b) användarprofilering. Resultatet visar att det intressanta i ett sådant nätverk är träningsresultatet och utvecklingskurvan. Nätverkets medlemmar är både sändare och mottagare och för att få tillgång till andra personers resultat måste man vara beredd på att visa sina egna resultat. Samtliga testpersoner tycks vara villiga till att dela med sig av sina resultat i större eller mindre utsträckning. Att dela med sig träningsresultat är en sekundär prioritering, det väsentliga är det personliga dokumenterandet av träningsresultatet. För att nätverket skall fungera i längden bör en profil dessutom vara sanningsenlig och tillförlitlig, ha kommentarer som kan hjälpa andra att bestämma träningsövningar och hjälpa en själv att ha kontroll på träningspassen samt möjlighet till normerade resultat som gör det mindre personligt och jämförbart med andra utövare. / This study examines digital motivation and user profiling to construct a set of guidelines that motivates users to engage in physical exercise, in a way that also encourage them to share workout documentation, training results and give recommendations in a digital network. It also examines people's thoughts at sharing the personal training results to others. This investigation is done in relation to an assignment where the client is involved in the development of an upcoming service which offers online documentation of physical workouts, mainly towards CrossFit. The qualitative study involved a test group of eight people with varied training knowledge and background. The study resulted in two different categories: a) motivation for documentation services in a digital network, and b) user profiling in a digital network within a training context. The conclusion shows that the significant part of this service is the individuals exercise result, visualized by a development curve in a way that makes it possible to compare your progress to others. Members of the network are both transmitter and receiver, meaning that in order to gain access to other people's results, one must be prepared to show its own results. All participants were willing to share their results to some extent. For the network to operate in the long run, user profiles must be truthful and reliable. Being able to make comments may be helpful to determine the exercise efficiency and suitability for oneself, but also for viewers seeking inspiration and suggestions on exercises. A normalized presentation of results is suggested, making the results less personal and comparable with other practitioners.

Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, Durban, South Africa, 2015. / Background CrossFit is a workout program developed in 2000 which involves high intensity interval training coupled with resistance training elements of powerlifting and gymnastics. CrossFit has grown to include competitive events and there are an ever increasing number of affiliate gyms internationally. CrossFit’s greatest criticism is related to safety. There is limited published data on the exercise program. Aims The aims of this study were: to determine a retrospective cohort analysis of the demographic, injury and treatment profiles of participants at the 2013 United We Stand CrossFit Games who presented to the Durban University of Technology’s sports treatment facility; to determine the association, if any, between demographics and injury types; and, to provide any recommendations regarding the clinical record form used. Methods This study was a retrospective, quantitative, descriptive study on the chiropractic Student Sports Association’s report form in order to produce a retrospective cohort analysis of the injury and treatment profiles. Persons who made use of the chiropractic treatment facility at the 2013 United We Stand CrossFit Games were required to complete an informed consent form. A sixth year chiropractic student then filled in a Chiropractic Student Sports Association report form to record participant, complaint and treatment information. The study was not limited to competitors, but all persons who had access to the chiropractic treatment facility. These forms were then collated and data captured on the complaints which presented and were treated at the chiropractic treatment facility. Results The data collected revealed that 137 participants presented to the chiropractic treatment facility in 162 visits, with 263 complaints treated. The age range of the sample was between 18 and 43 years, with a mean age of 27.49 years. The majority of participants who presented to the CTF were competing athletes and just under half of the study sample reported to not having a history of previous injury. The study found that the lumbar region (20.9%), wrist/hand (14.4%), shin/calf (11.0%) and knee (10.2%) were the most commonly presented regions of complaint. The highest presenting mechanism of injury was that of overuse (22.4%) followed by running (19.0%). Acute injuries accounted for 72.20% of all injuries. With regards to diagnoses, myofascial trigger points made up 21.6% of all injuries, followed by muscle strains (19.7%). Facet syndromes of the spinal column accounted for 13% of diagnoses.It was shown that kinesiotape, manipulation, massage and ischemic compression were the top treatment interventions utilised. It was also shown that rest, ice and referrals were types of treatment that were not utilised. Due to statistical inconsistencies no significance tests were possible between demographic and injury characteristics. Recommendations were proposed in order to maximise the quality of data captured. Conclusion: The results add insight into the injuries presented and the treatment they acquired at the chiropractic treatment facility at a national CrossFit event. The most common injuries require investigation in both training and competitive environments. Various recommendations have been proposed for the record form used at sporting events in order to facilitate the collection of high quality data. / M

Estas interações simbólicas da vida corrente de uma microssociedade urbana contemporânea serão descritas por meio de relato etnográfico. A partir da percepção de dimensões intersubjetivas de pertencimento e de produção de significados afetivos, discutiremos os dados de campo a partir de um referencial teórico que compreende as noções de Estética (Maffesoli), Intersubjetividade (Schutz), Tipificação (Schutz) e Conflito (Simmel), relacionadas aos usos do Corpo (Mauss) e suas Performances (Schechner). Esse referencial teórico nos parece propício para interpretar os fenômenos comunicativos percebidos durante a pesquisa de campo, já que o estudo da intersubjetividade corresponde a uma perspectiva nova de análise de fenômenos comunicacionais. Essa abordagem compreende a comunicação como o fenômeno estruturante das mediações culturais da vida social. Portanto, aqui intencionamos abordar a comunicação enquanto conhecimento que se insere na esfera da ação da experiência humana, atrás daquilo que é relacional e compartilhado. / This research is part of the researcher's insertion in a CrossFit box, observing and experiencing the moments during, during and after training, in the search for understandings that understand the communicative experiences produced among the practitioners of the sport. These symbolic interactions of the current life of a contemporary urban micro-society will be described through an ethnographic account. From the perception of intersubjective dimensions of belonging and production of affective meanings, we will discuss the field data from a theoretical reference that includes the notions of Aesthetics (Maffesoli), Intersubjectivity (Schutz), Typification (Schutz) and Conflict (Simmel), related to the uses of the Body (Mauss) and its Performances (Schechner). This theoretical reference seems to us propitious to interpret the communicative phenomena perceived during field research, since the study of intersubjectivity corresponds to a new perspective of analysis of communicative phenomena. This approach comprises communication as the structuring phenomenon of cultural mediations of social life. So here we intend to approach communication as knowledge that falls within the sphere of the action of human experience, behind that which is relational and shared.

Dentre os estudos existentes, o tema mais frequentemente encontrado é o de lesões, com a articulação do joelho sendo umas das partes corporais mais lesionadas. Um teste comumente utilizado para predição de lesões no joelho é a Razão Isquiotibiais/Quadríceps (razão I/Q), que avalia o equilíbrio entre os músculos flexores e extensores do joelho. O objetivo do estudo foi analisar o equilíbrio muscular da articulação do joelho em adultos praticantes de CrossFit, musculação e sedentários. Participaram do estudo 47 homens saudáveis (idade: 25,81 ± 6,2 anos, massa: 81,24 ± 14,86 kg) alocados em grupo de praticantes de musculação (TRM), grupo de praticantes de CrossFit (TRC) e grupo de sedentários (SDT). Picos de torque, coletados em um dinamômetro isocinético, foram utilizados para cálculo da razão I/Q. As comparações entre grupos foram realizadas por meio de ANOVA one way. Não foram encontradas diferenças significativas entre grupos para a razão I/Q de membro dominante. Entretanto, a razão I/Q de membro não-dominante foi significativamente maior no grupo TRC comparado ao grupo TRM (p<0,05). Também o pico de torque relativo à massa corporal no quadríceps foi significativamente maior no grupo TRM comparado ao grupo SDT e o pico de torque relativo à massa corporal nos isquiotibiais foi maior no grupo TRC comparado ao grupo SDT. Acredita-se, portanto, que possíveis lesões de joelho, frequentemente ocorridas entre praticantes de treinamento resistido, estejam mais provavelmente relacionadas à técnica de execução dos exercícios em si, que ao equilíbrio muscular. / One of the types of resistance training that has grown most in recent years is CrossFit. However, there are few studies with that practice this kind of training. Among existing studies, the most frequently encountered theme is that of injuries, with the knee joint being one of the most injured body parts. A commonly used test for knee injury prediction is the Hamstring to Quadriceps Strength Ratio (H/Q ratio), which assesses the imbalance between the knee flexor and extensor muscles. The aim of the study was to analyze the muscular imbalance of the knee joint in adults who do CrossFit, traditional weight training and sedentary men. Forty seven healthy men (age: 25.81 ± 6.2 years, mass: 81.24 ± 14.86 kg) participated in the study and were allocated in groups of men who do traditional weight training (TRM), who do CrossFit (TRC) and sedentary (SDT). Peak torques, collected on an isokinetic dynamometer, were used to calculate the H/Q ratio. Comparisons between groups were made using one way ANOVA. No significant differences were found between groups for the dominant leg’s H/Q ratio. However, the non-dominant H/Q ratio was significantly greater in the TRC group compared to the TRM group (p<0.05). Also, the relative peak torque in the quadriceps was significantly greater in the TRM group compared to the SDT group and the relative peak torque in the hamstrings was significantly greater in the TRC group compared to the SDT group. It is therefore believed that possible knee injuries, often occurring among resistance-training individuals, are probably more related to poor technique and not to muscle imbalance.

The theme of this thesis is sports diet. It is divided into two parts. A theoretical part explains balanced died. It describes the mechanics of energy generation during physical activity and the characteristics of rowing and Crossfit. The focus is on diet in those disciplines. Based on the theoretical foundation is build a practical part, where the statistical data are analyzed and evaluated. The goal of this thesis is to discover, whether there is a difference between rower's and Crossfit athlete's diets. To find out, specialized questionaries about eating habits have been used. Sixteen sportsmen/sportswomen have filled the questionaries. Based upon collected data about their intake of selected nutrients in the last month, there were no statistically significant differences in energy income, protein consumption (neither animal nor plant-based), amount of fruit and vegetables, fatty acid spectrum nor added sugar income. The data have nonetheless indicated differences, eg. Crossfitters tend to have higher animal protein consumption and lower intake of fruit. Key words: crossfit, eating habits, nutrition, rowing, sport diet
