Professional tennis is a unique sport in which players travel thousands of miles every year in a continual pursuit of ranking points to increases, stabilise, or improved their world ranking position. The accumulation of points leads to a higher ranking, which in turn grants entry into higher level tournaments offering higher points and increased prize money. In a cyclical manner, a player travels, competes until elimination, then travels to the next tournament. During which the player experiences a variety of playing surfaces, environments, and opposition playing styles. Depending on tournament progression, these periods are interspersed with training blocks of varying duration. Despite literature outlining the technical aspects and performance analysis of tennis, the acute physiological impact of point play and physiological characteristics of players, the nutritional requirements are not well understood. No research has investigated the habitual physical demands experienced by the professional player using fieldbased measurement tools.The first study examined the energy expenditure of two world class tennis players (one male, one female) competing at the highest level, the Wimbledon Championships, following a week playing at the Eastbourne International tournament. For the first time, in using the gold standard method in doubly labelled water, the total daily energy expenditure (TDEE) of elite tennis was reported. During analysis, the TDEE for the female player was 3383 kcalxd-1during the first week and 3824 kcalxd-1during the second. Likewise, the male TDEE was 3712 kcalxd-1for the first week and 5520 kcalxd-1for the second. During energy expenditure measurement, corresponding match data (points played, shot count, distance covered) show the characteristics of match play were reflective of that previously reported at Grand slam level. The study reported that elite tennis played at the highest level is a high energy demanding sport.In study 2, the player group was broadened to create a wider understanding of the energy demands highlighted in study 1. In doing so, the doubly labelled water technique was once again employed with female players ranked between 100-200 during WTA grass court tournaments, a junior player during International Tennis Federation J1 and Wimbledon Juniors, and a male doubles player during Wimbledon Championships. The TDEE for the male doubles player was 4586 kcal·d-1and lower than that of the male singles player measured during study 1. Although less matches were played by the doubles player, a similar amount of points were played between the two players. One female player was injured on day 1. Data collection continued as an opportunity to investigate the energy requirements of injury and early stages of recuperation from surgery showing Total Daily Energy Expenditure of 2583 kcal·d-1. Noninjured adult female participants TDEE were 3396 and 3948 kcal·d-1, with the junior player TDEE was 3988 kcal·d-1. Even with a lower match count than that reported in study 1, energy expenditure was similar for the uninjured female players as that of the female player in study 1. The energy expenditure data of a wider group of players reflected study 1, finding elite tennis to be a highly energetically demanding sport.
