Case study 1Julie is a long distance swimmer for Victoria. Her favourite events are 800m and 3km freestyle. She trains 4 mornings a week and 4 afternoons a week. She is really focusing on maintaining the same speed for a long distance of time. Julie's aim is to get into the Olympics one day to represent her country. At this stage she is really struggling to get a good start and being able to increase her speed in the last 100m.List the 2 fitness components that are likely to be her best?*2 points

usan recently began racing her bicycle. Her training consists entirely of long rides at a steady pace. When she entered her first race, she was excited that she was able to keep pace with the rest of the riders. However, during the final sprint to the finish line, the other riders left her in their dust, and she finished in last place. Why was she unable to keep pace during the finishing sprint?Susan’s training of long runs at a steady pace has stimulated growth of her Type muscle fibers.  Additionally, some of her Type II fibers had been converted to Type I fibers.    However, she faded at the sprint to the finish because she had neglected to train her Type muscle fibers.  As her muscles increasingly began to engage in more anaerobic respiration, her lack of strength in her or fiber type was most apparent.As her coach, which of these activities would you recommend to Susan when training for her next race?check all that applyIncrease the length of her training runsunansweredSprinting drillsunansweredCross-country skiingunansweredLifting weightsunansweredJumping drills
