15 participants completed a two-week, single-arm, prospective study was to determine if elite pickleball athletes can improve quality of life with nutrient-dense foods. Subjects, with an average age of 55 ± 8 years, were recruited at a competition and were all avid players. Three nutrient-dense foods were provided daily – a brain-enhancing shake to improve focus, a bar to increase energy, and a hot meal to help with endurance and recovery.
10 general quality of life questions used a rating system of 1 to 5, with 5 being the best.
4 pickleball-targeted questions were asked using Yes (noticed a change) or No (no change). Three of these four were also asked using the numeric rating system.
