Abstract
Table tennis is a racket sport characterised by an intermittent movement profile, including short rallies interspersed with short breaks. In contrast to other racket sports, information is lacking regarding the: (i) physiological responses during table tennis matches and training; and (ii) practical recommendations for enhancing aerobic and anaerobic performance in table tennis by improving cardio-metabolic and neuro-muscular fitness, anthropometry and nutritional strategies. Therefore, this review article attempts to narratively provide an overview of the physiology of table tennis by describing the metabolic mechanisms underlying match play and outlining a framework for practical recommendations for improving cardio-metabolic and neuro-muscular fitness, anthropometry as well as nutritional strategies. A second aim was to stimulate future research on table tennis and to point out study limitations in this context. In general, the most important finding is that the rally duration is short at around 3.5s, with a longer rest time of around 8-20s, resulting in an effort-rest ratio ranging from 0.15 to 0.22 in official matches and energetic demands during match relatively low. Future studies should focus on the relationship between energetic demand and table tennis performance with a view to predicting performance in table tennis using physiological parameters.

Abstract
Competitive tennis in the heat can prompt substantial sweat losses and extensive consequent body water and electrolyte deficits, as well as a level of thermal strain that considerably challenges a player's physiology, perception of effort, and on-court well-being and performance. Adequate hydration and optimal performance can be notably difficult to maintain when multiple same-day matches are played on successive days in hot weather. Despite the recognised effects of the heat, much more research needs to be carried out to better appreciate the broader scope and full extent of the physiological demands and hydration and thermal strain challenges facing junior and adult players in various environments, venues and competition scenarios. However, certain recommendations of best practices should be emphasised to minimise exertional heat illness risk and improve player safety, well-being and on-court performance.

Abstract
Improving the recovery capabilities of the tennis athlete is receiving more emphasis in the research communities, and also by practitioners (coaches, physical trainers, tennis performance specialists, physical therapists, etc). The purpose of this article was to review areas of recovery to limit the severity of fatigue and/or speed recovery from fatigue. This review will cover four broad recovery techniques commonly used in tennis with the belief that the interventions may improve athlete recovery and therefore improve adaptation and future performance. The four areas covered are: (1) temperature-based interventions, (2) compressive clothing, (3) electronic interventions and (4) nutritional interventions.

Fatigue in tennis: mechanisms of fatigue and effect on performance.

Sports medicine (Auckland, N.Z.). 2007;(3):199-212
Abstract
This article reviews research sourced through sport science and medical journal databases (SportDiscus and PubMed) that has attempted to quantify the effects of fatigue on tennis performance. Specific physiological perturbations and their effects on common performance measures, such as stroke velocity and accuracy, are discussed. Current literature does not convincingly support anecdotal assertions of overt performance decrements during prolonged matches or matches played during unfavourable (e.g. hot and humid) environmental conditions. The constraints of field-based research have presented, and continue to present, a methological challenge to investigators within this domain. Limitations of previous investigations have included the following: (i) a restricted measurement approach to the multifaceted skills that form the basis of match performance; (ii) a lack of sensitivity and large variability in skill or performance measures; (iii) usage of non tennis-specific methods to induce fatigue; and (iv) fatigue levels failing to reflect those recorded in match play. Hyperthermia, dehydration and hypoglycaemia have all been identified as common challenges to sustained performance proficiency in tennis, with emerging evidence suggesting central fatigue may also be a key stressor. Mixed results underpin attempts to mitigate physiological compromise and in situ performance deterioration through application of potential ergogenetic strategies (e.g. carbohydrate and caffeine supplementation, and hyperhydration). Methodological limitations are again a likely explanation, but positive findings from other skill-based sports should encourage further research in tennis. To date, tennis has largely relied on traditional methods to measure performance and has not yet realised the benefits of new sports science methods. Future research is encouraged to adopt methodological approaches that capture the multi-dimensional nature of tennis. This can be achieved through the incorporation of multifaceted performance assessment (i.e. perceptual-cognitive and biomechanical measurement approaches), the improvement of measurement sensitivity in the field setting and through the use of experimental settings that accurately simulate the energetic demands of match play.

Abstract
Carbohydrate supplementation in prolonged aerobic exercise has been shown to be effective in improving performance and deferring fatigue. However, there is confounding evidence with regard to carbohydrate supplementation and tennis performance, which may be due to the limited number of studies on this topic. This evidence based review, using database searches of Medline and SPORTDiscus, summarises the limited relevant literature to determine if carbohydrate supplementation benefits tennis performance, and, if so, the appropriate amounts and timing. Although more research is required, it appears that it may be beneficial in tennis sessions lasting more than 90 minutes.

Abstract
During the past decade, the physical and mental stress in professional tennis has been constantly increasing. The overall intensity in tennis ranges between 60 and 70% of maximum oxygen uptake and the energy requirements are mainly provided by aerobic energy metabolism. Therefore, particularly with respect to the duration of the tournaments and the length of the matches, a good aerobic capacity promotes continuous success in professional tennis. During frequent periods of high intensity, however, muscular energy is derived from anaerobic glycolysis. Therefore, sports-specific conditioning programs in tennis should improve both glycolytic and oxidative muscular metabolism. Years of training and competition induce a number of cardiovascular and metabolic adaptations: an increase in heart size in terms of an athlete's heart, higher oxygen uptake capacity, improved muscular oxidative enzyme activities, reduced baseline catecholamine levels, and a lower resting heart rate. In addition, tennis induces side-specific increments in bone density, bone diameter, and bone length of the upper extremity. Furthermore, structural and functional adaptations of the conducting arteries in the preferred arm could be demonstrated in professional tennis players. In conclusion, tennis is a very complex sport involving strength, power, speed, agility and explosiveness, as well as endurance components. Scientific data on exercise-related cardiovascular and metabolic parameters in professional tennis are important to evaluate the players individual fitness level and will help to improve sports-specific conditioning programs. This in turn will not only enhance performance but also prevent overstrain and burnout syndromes.
