The parameters which may be measured are biochemical, genetic, metagenomics in stools or even urinary metabolites associated with individual exercise and which are encompassed by the new “omics” of sports or “sportomics”.</p><p id="par0020" class="elsevierStylePara elsevierViewall">Measurement of these parameters at different times during the season offers a more accurate overview of the player, their baseline values, their best values, and also the changes which may appear in each sportsperson during the preseason and competition. This control is particularly important during the busiest periods, when they may compete up to 3 times per week, with trips that involve time changes and when there are under 72<span class="elsevierStyleHsp" style=""></span>h between matches, with the difficulty this entails for adequate physical and mental recovery.</p><p id="par0025" class="elsevierStylePara elsevierViewall">The ability for fast recovery after different types of exercise or <span class="elsevierStyleBold">resilience</span> differs between players or even in the same player at different times, and is currently one of the key aims for improvement and under study. It encompasses many aspects of both external and internal load control which may be modified and trainable for improved condition of the sportsperson.</p><p id="par0030" class="elsevierStylePara elsevierViewall">One of the new challenges in the area of sports medicine is to identify and measure potential causes of fatigue and use them to design a plan or strategies for the individual. The approach may therefore differ depending on their genetics, but especially on the appropriate expression of these genes <span class="elsevierStyleBold">or epigenetic,</span> which includes evaluation of the different effects of workloads on physical performance parameters measured using GPS, body composition, healthy diet, rest and mental control, producing the sportsperson's phenotype.</p><p id="par0035" class="elsevierStylePara elsevierViewall">There are increasingly more biomarkers to assess whether appropriate adaptation to exercise has been made, which demonstrate progressive improvement or, on the contrary, an increase in inflammation indicators, over-training, and risk of lesion.</p><p id="par0040" class="elsevierStylePara elsevierViewall">It is important not to evaluate the different markers independently and separately from one another, but to assess the situation globally, taking measurements at the most appropriate moments, taking into account any changes made at each moment and any inter-individual differences.</p><p id="par0045" class="elsevierStylePara elsevierViewall">Rest periods, pre-seasonal periods, the different moments of the competition and the scheduled 2–3 matches per week are situations in which the objectives and results obtained should be evaluated differently and the strategies to apply must also be personalised at these times.</p></span><span id="sec0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Applicability of concepts</span><p id="par0050" class="elsevierStylePara elsevierViewall">One practical example of the applicability of the explained concepts may be the family of cytokines of which interleukin 6 (IL-6) is one. With its duel significance dependent upon time of measurement, it is a stimulus for muscle recovery immediately after exercise, but is also an indicator of accumulated inflammation when it progressively increases over time.</p><p id="par0055" class="elsevierStylePara elsevierViewall"><a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a> demonstrates how as the season progresses and training sessions and matches accumulate, markers such as IL-6 which presented low values in most of a team at the beginning begin to increases despite providing recovery strategies such as nutrition and supplements with complementary antioxidants such as curcumin or tart cherry juice.</p><elsevierMultimedia ident="tbl0005"></elsevierMultimedia><p id="par0060" class="elsevierStylePara elsevierViewall">Another example could be raised levels of homocysteine which is an indicator of cardiovascular risk in the general population, but which has another significance as of yet unclear in sportspeople. In high-level competitive players this marker is often raised and high quantities of group B vitamins are required to control it. Its increase is often linked to unfavourable genetic variants of the methylation MTHER gene, and its determination may be useful for personalised supplementation with these vitamins. Other examples may be seen in <a class="elsevierStyleCrossRef" href="#tbl0010">Table 2</a>.</p><elsevierMultimedia ident="tbl0010"></elsevierMultimedia><p id="par0065" class="elsevierStylePara elsevierViewall">The player trains and competes for limited periods of time when exercise provides global and major stimulus for the body, with a marked inflammatory, hormonal and immune response. However, for the rest of the day the opportunity arises to control basic aspects such as rest, diet and digestion, among other factors, which may help to optimise adaptation and progressive improvement of the sportsperson's performance.</p><p id="par0070" class="elsevierStylePara elsevierViewall">In this regard, knowledge of genetic polymorphisms associated with individual sensitivity to, for example, caffeine, gluten or lactose may promote an individualised approach and specific personalised nutrition and medicine for the sportsperson.</p><p id="par0075" class="elsevierStylePara elsevierViewall">During the season it is essential to be intimately aware of the player's development and their best values in order to work increasingly on the aspects which may specifically be improved.</p><p id="par0080" class="elsevierStylePara elsevierViewall">Fatigue is regarded as the perceived incapacity to carry out planned exercise. Here not only muscle factors are considered to be reflected in the biomarkers showing the accumulation of lactate and acidosis, inflammation or immunity (peripheral fatigue) but on occasion the actual levels of these indicators may be high but well tolerated by the sportsperson thanks to their motivation and ability to cope with them due to their response or mental fatigue acting in a completely different way.
