Sports nutrition in swimming

Sports regimen in swimmingBMS-3033 fun NUTRITION URN6041693Choose a sport of your choice. Critically discuss the nutritional requirements of this sport. Give examples where appropriate to exemplify your answerSwimming is a very competitive sport worldwide with different events like 50 to 1500 meters with time duration of 22s to 16 minutes respectively. Moreover, with four different strokes freestyle, butterfly, breaststroke and backstroke. With typical reproduction programs with the find to increase lean body mass, and decrease body fat levels over the season Petersen et al. (2006). Sport nutrition plays a very important role especially for elite athletes. The goal of this essay is to discus to a greater extent specifically the dietary needs for athletes that compete in the 50 and 100 meters distance events.In the 50 and 100 meters events in particular event swimmers relies on the production of large power outputs with highly unified and efficient technique in a short range of time. This power output rely on the anaerobic glycolysis and high energy phosphates. Therefore, the main type of muscle fibre developed in athletes in facts of life for 50 and 100 meters event is Type2 a and 2 b of muscle referable to the travel of contraction, short length of time, anaerobic capacity using high energy phosphates (ATP and creatine phosphate) and glycogen as fuel, however due to the nature of the high intensity aerobic activity with training sessions from 1.5 up to 4 hours a day there is no question that type 1 fibres muscle is developed.Trainingboilersuit training programs for elite swimmers are based on experience of successful coaches rather than scientific tell of superior performance outcomes. There seems to have difference in opinions among coaches regarding to training sessions. Some opt for training only in the pool and others use less sessions in the pool (more specific training) but amount cycling and running sessions to improve aerobic capacity.Genera lly the pool workouts consist of aerobic warm-up and sedate downs, training aims to improve techniques in starts and turns, and sets of repeated bouts of swimming at different intensities depending on the goal wanted, in this case sprint. Moreover, generally 40% of the training intensity less than 80% of VO2max, from 40% to 60% at intensities of 80% vo2max, and less than 5% at 100% Vo2max.Sherman and maglischo (1992) have estimated the energy requirement of swimming training at approximately 16.8 to 22.6 MJ.day-1(4000-5400 kcal.day-1) for males working 4 hours a day and between 14.2 to 16.8 MJ .day-1(2400-4000kcal.day-1) for females working 4hours a day, although these factors will transmute within each athlete physical condition and technique performance.Nutritional ChalengesThe nutritional issues and challenges for swimmers are to launch a nutrition strategy to provide fuel to cope with large energy demand, promote recuperation for each session, achieve optimal levels of lean body mass and body fat as come up as keep the vitamins and minerals within normal levels during the different phases of training in the season (E.g. high heap training, taper or off-season).However, swimmers struggle to cope with large energy needs not only for training but for competition some common issues are presented belowTrainingHigh energy requirements due to fluctuations in growth patterns (growth spurt in adolescents), changes in training volume or simply alert gain of muscle mass.Irregular eating patterns due to a busy time table.Social and heathen issues.Poor nutritional knowledge.Adjusting energy intakeCompetitionAdjusting energy intake during taper to prevent exuberant gain of weight and body fat.Adequate fuel stores for the day of competition.Postrace recovery between different competitions or between heats, semifinals, and finals.Training program vs. competition nutritional requirementTherefore the nutritional requirement in order of priority for pre-training, tr aining and post training (same for competition) are rehydration, refuelling and recovery.Pre-trainingTrainingPost training reflection in use of supplements.
