It is important to investigate how the golf swing changes with extended play because fatigue affects the performance of athletes playing sports similar to golf. Golf is a physically demanding sport when playing 18 holes while walking and carrying a bag. The effect of playing 18 holes of golf on the mechanics and swing outcome of the golfer are currently unknown. The knowledge of how extended play affects the golf swing will aid golfers, golf coaches, and researchers in understanding proper golf training and play affected swing mechanics. This study investigates the effect of playing 18 holes of simulated golf on the mechanics and performance of the golfer. A total of seven male and female recreational golfers scoring between 80 and 95 on 18 holes of walked golf were recruited for 3-D motion analysis of 140 tee shots. Mechanical variables and outcome variables at three phases of the golf swing were tested over time to evaluate the relationship between time (playing golf), mechanical variables, and the outcome of the golf shot tested statistically using path analysis. Weight transfer to the lead leg at ball contact was significantly related to club head velocity (CHV). Over time, golfers were less able to achieve a weight transfer to the lead leg, which was directly related to the golfers' club head velocity. The lead knee and lead ankle angles were also affected by time, which had an influence on club head velocity. These results suggest that golfers do change their swing throughout the course of 18 holes of walked golf and there are key swing mechanics which significantly influence golf performance. / School of Physical Education, Sport, and Exercise Science

The idea of doing a golf bag as my master thesis came to me due to my own experiences from playing golf for almost a decade. I use a carry bag because it gives me freedom to go wherever I want on the golf course, and doing it faster than if I would use a trolley. To be able to move in a smooth and pleasant way, you need good equipment. Golf bags on the market today are unnecessarily large. This is something that I can’t understand. It must be possible to design a golf bag that is compact and easier to use. With innovative ideas I tend to make a conceptual golf bag that is more compact and user friendly. It will inspire more golfers to use a carry bag which in the end will lead to a faster game on the golf course. Finally I will present a physical model that best reflects how the concept would look if it were manufactured. I offer golfers an opportunity to carry their golf equipment in a more convenient way. The golf bag is easy to use, especially on the track, but also in transportation to and from the golf course and when it is stored at home. I have set out to try to find new ways of thinking, which offers golfers equipment that differ from today. New ideas have been combined with ergonomics and design. The work begins with a sketch phase. Five different conceptual ideas are developed. Decisions are made to work on Concept E. It is a small bag that is worn on the lower back. The decision was based on the simplicity of the concept. There are also similarities to the golf bags on the market today. This is a good thing as it will be easier for golfers to connect to the bag and it may have a better chance of entering the market. I ended up with Copilot. It is a golf bag that is compact and slim in its design. The strength lies in the elastic pockets. They will adapt depending on what is stored in them. Therefore is the bag not bigger than what the user makes it. The golf bag is designed in a way that hold the clubs in place so they will not be in contact with each other and cause disturbing noise. Copilot helps golfers to feel relaxed, but at the same time be ready and alert on the golf course. The simplicity, clarity and flexibility are three core values that makes this golf bag the obvious choice for the golfer who wants to focus on their game. / Bakgrunden till projektet ligger i att jag har spelat golf i närmare tio år. Jag använder mig av en bärbag då det ger mig friheten att röra mig snabbare över golfbanan. För att röra sig på ett smidigt och behagligt sätt gäller det att använda en bra utrustning. Golfbagarna som finns idag är otympliga och onödigt stora. Jag ställde mig frågande till det. Det måste gå att utforma golfbagen på ett kompakt och mer användarvänligt sätt. Det var den frågan jag ville undersöka i mitt examensarbete. Jag ska med hjälp av nytänkande idéer arbeta fram ett konceptförslag på hur golfbagen kan göras mer kompakt och användarvänlig. Den ska inspirera fler golfare till att använda bärbag vilket i sin tur leder till ett snabbare spel på golfbanan. Projektet avslutas med att jag presenterar en fysisk modell som på bästa sätt återger hur konceptet ser ut i ett tillverkat skede. Med mitt koncept erbjuder jag golfaren en möjlighet att transportera sin golfutrustning på ett bekvämt och ur storlekssynpunkt mer effektivt sätt. Utrustningen ska upplevas smidig, främst på banan, men även i transporten till och från golfbanan samt när den förvaras i hemmet. Jag eftersträvade ett nytänkande, något som erbjuder golfaren en utrustning som skiljer sig från dagens. Nytänkandet kombinerades med ergonomi och form. Arbetet inleddes med en skissfas där fem olika konceptförslag tas fram. Beslut togs att jobba vidare med koncept E. Det är en smal bag som bärs horisontellt mot ryggslutet. Beslutet grundar sig i konceptets enkelhet och hur användandet har likheter med dagens bärbag. Med kopplingarna till dagens bärbag ansågs konceptet vara lättare för golfaren att ta till sig och bagen kan ha en större chans att komma ut på marknaden. Resultatet blev golfbagen Copilot. Bagen är en kompakt och slimmad i sin form. Styrkan ligger i de elastiska fickorna. Fickorna anpassar sig efter vad som packas ner i dem och bagen blir på så sätt inte större än vad användaren gör den till. Copilot löser ett ständigt återkommande problem, problemet att klubborna slås emot varandra när man går med bagen på ryggen. Bagens ovandel är utformad med låsning av klubborna. Klubborna kilas fast i bagen och kommer inte i kontakt med varandra när användaren går med bagen på ryggen. Copilot bidrar till att golfaren känner sig avslappnad på golfbanan, men samtidigt förberedd och alert. Enkelhet, tydlighet och flexibilitet är tre värdeord som gör golfbagen till det självklara valet för den golfspelaren som vill fokusera sin energi på sitt spel.

<p>The purpose of this study was to retrospective investigate perceived demands and barriers for</p><p>golf juniors in their transition from regional to national junior elite competitions, and to find</p><p>out what resources and coping strategies the juniors used to succeed with this transition. The</p><p>developmental model (Wylleman & Lavallee, 2004), The analytical career model</p><p>(Stambulova, 2003) and The athletic career transitions model (Stambulova, 1997; 2003) were</p><p>used as theoretical framework for this study. The interviews were conducted with nine junior</p><p>golf players. A semi-structured interview guide was used consisting of five main themes:</p><p>background information, changes/demands experienced in the transition, resources that helped</p><p>the golf juniors to adjust to the new level, strategies the golf juniors used to adjust to the new</p><p>level and an evaluation of the transition. The result showed that the players perceived the</p><p>practice as more serious with an overall higher quality when they started to compete in</p><p>national competitions. The players increased their training time and started to use a variation</p><p>of exercises that were similar to the different parts of a competition. The competitions were</p><p>also perceived as more challenging with stronger opponents and an increased rivalry between</p><p>the players. Confidence and self-esteem, the will to practice and win are characteristics that</p><p>many players consider to be important internal resources in order to adapt to the national</p><p>junior level. The players observed other players to learn from them and to see what they</p><p>needed to improve. Many players changed their golf coaches around the same time as they</p><p>started to compete at national junior level. The coaches and parents were seen as the most</p><p>important external resources in order to adapt to the national junior level. Many players</p><p>experienced that it would have been hard to play and compete in golf without their parents’</p><p>financial help and support. During the time of the transition, outside golf the players learned</p><p>how to take responsibility and how to take care of themselves through traveling alone,</p><p>meeting new people and living by themselves. The players experienced that the school didn’t</p><p>have any understanding for their need to be free from school. The players also had to give a</p><p>lower priority to some other things in their life in order to have enough time for golf. The</p><p>biggest change was that they had to spend less time with their friends and the different</p><p>activities that they used to do before.</p>
