Aim. The article aims to assess the body reserves of ski racers who develop local-regional muscle endurance (LRME), statokinetic and hypoxia resistance. Materials and methods. 15–16-year-old highly skilled ski-racers (I, II category, candidates for master of sports) with sports experience of 5–7 years (n = 12) were examined. The following equipment was used to assess athletic fitness and sports performance: T 2100 GE treadmill system, CardioSoft diagnostic system (USA), HYPOXICO Everest Summit II altitude generator (USA), Angio Scan-01 P pulse oximeter sensor (Russia). Statistical analysis was performed using the SPSS information processing package. Results. The effect of techniques for developing LRME and hypoxia resistance on sports performance has been established. A generalized ranking of competitive performance is constructed and a regression model is described that establishes the dependence of sports performance on morphofunctional and metabolic statuses. The key indicators of morphofunctional and metabolic statuses were compared in athletes who used the methods for developing LRME and hypoxia resistance. Criteria are established for successful performance in sports reserve training, promising cross-country skiers, the modeling of status indicators with well-established technologies while maintaining the functional and metabolic potential and the level of health. Conclusion. The results of the study showed the effectiveness of combined technologies in sports training and allowed to identify markers of functional and metabolic statuses. The proposed technologies allowed to enhance adaptation and identify status markers. This made it possible to improve performance in the conditions of LRME and statokinetic and hypoxia resistance. Forecasting sports results allows regulating athletic fitness and making timely corrections to ensure successful sports performance.

In the study, it is aimed to determine whether there is any improvement in the physical performance development of the individuals, who have made exercise with OPT MODEL -EMS mix. and traditional PT models within the 20-week exercise program. In the study, pre-test, posttest, experimental screening by pattern methods are used. Study groups consist of 30 individuals, who are healthy and voluntary, continuing the fitness centers in Netherlands (OPT-EMS; n=30) and in Turkey (PT; n=30). After the data obtained is entered in computer environment; the arithmetic means (X), standard deviations (ss) of the research groups are taken and the Paired Samples t-test is applied for the differences between the pre-test and posttest. Significance level is examined at p<0.05 level. When the study findings are examined, statistically significant differences are observed in the push-up, squat, crunch, plank and Max Vo2 performance measurements of the participants in 20-week OPT-EMS group (p<0.05). Also, a statistically significant difference is found in the left hand grip and plant test performance measurements of the participants in 20-week PT group (p<0.05).As a result, the OPT model, which is an innovative approach and has five different training phases, and the continuation of training with EMG for a certain period of time can be said to contribute to the physical performance. In addition, in case PT training content is prepared according to the individual, it is considered that it will contribute to physical performance.

The purposes of this study were to investigate effects of partial block periodized strength training on physical performance and to examine relationships between initial muscle strength measured with isometric mid-thigh pull (IMTP) and performance changes after 7 weeks of strength training. Seventeen collegiate male soccer players participated. Initial muscle strength was determined using IMTP while physical performance included 10 m and 20 m sprints and static vertical jump with a polyvinyl chloride pipe (SJ0), 20 kg barbell (SJ20), and barbell loaded to 40 kg bar (SJ40). Performance testing was performed at three points: before first week (baseline), fourth week (T1), and seventh week (T2). Statistically small to moderate changes were found from baseline to T2 in peak power (PP; p < 0.001, ES = 0.49), net impulse (NI; p < 0.001, ES = 0.49), peak velocity (PV; p < 0.001, ES = 0.62), allometrically scaled PP (PPa; p < 0.001, ES = 0.62) in SJ20 and jump height (JH) in SJ40 (p < 0.001, ES = 0.36). Moderate to large correlations were found between isometric peak force and the changes from baseline to T2 in SJ20 PP (p = 0.04, r = −0.49), SJ20 PF (p = 0.03, r = −0.52), PPa (p = 0.04, r = −0.50), and SJ20 allometrically scaled peak force (p = 0.04, r = −0.49). Properly structured strength training maximizes task-specific physical performance. Initial muscle strength negatively affects the magnitudes of adaptations to physical performance.

Vegetarianism has been getting increasing attention over the years, in society in general and in sport in particular. However, the growth in the number of people following a meatless diet notwithstanding, vegetarianism should be practiced with caution, especially by professional and recreational athletes, considering the possible lack of certain nutrients and decline in their physical performance. Therefore, the present review aimed to determine whether following a vegetarian diet influences recreational and professional athletes’ physical and sports performance. A search of the databases Medline/Pubmed, Scopus, Web of Science, and Lilacs gave 343 relevant articles; however, only 15 of these focused on the vegetarian diet and physical performance, in accordance with the inclusion criteria. These studies compared the vegetarian diet with the omnivorous diet, and found that it did not negatively influence physical performance. Moreover, those who followed a vegetarian diet seemed to have a higher volume of maximum oxygen (V̇O2 max), which positively influenced their performance. In conclusion, following a plant-based diet does not seem to harm recreational and professional athletes.

The purpose of this study was to investigate the effects of six weeks of small-sided games (SSG), speed endurance (SER) and combined SSG and SER (CT) training programs on sprint, repeated sprint, Yo-Yo intermittent recovery test level 1 (Yo-Yo IR1) and level 2 (Yo-Yo IR2) performance in young soccer players. Forty-one elite young soccer players (body height: 174.0 ± 7.5 cm, body weight: 59.7 ± 9.5 kg, age: 14.6 ± 0.5 years, training age: 7.4 ± 0.6 years) underwent anthropometric measurements before performing 10m and 30m sprint tests, repeated sprint tests, and Yo-Yo IR1 and Yo-Yo IR2. The players were then divided into four groups: the SSG group (SSG; n=11), the SER group (SER; n=10), the CT group (CT; n=11), and the control group (CG; n=9). All groups performed training for six weeks on two days out of the five training days the participants were undertaking. There was a statistically significant increase in the Yo-Yo IR1 and Yo-Yo IR2 test performances of players in SSG, SER and CT groups (p&lt;.05). In addition, players in these groups showed significantly higher percentage increases in Yo-Yo IR2 test performance compared to the CG. The CT group also had a statistically significant increase in Yo-Yo IR1 test performance compared to the CG (p&lt;.05). In conclusion, while this study shows that SSG and SER training can be used for physical performance development in isolation or in combination, coaches and sports scientists are advised to choose combined training to use training time more efficiently.

Blood Doping

Optimum performance in aerobic sports performance requires an efficient delivery to, and consumption of, oxygen by the exercising muscle. It is probable that maximal oxygen uptake in the athlete is multifactorial, being shared between cardiac output, blood oxygen content, muscle blood flow, oxygen diffusion from the blood to the cell and mitochondrial content. Of these, raising the blood oxygen content by raising the haematocrit is the simplest acute method to increase oxygen delivery and improve sport performance. Legal means of raising haematocrit include altitude training and hypoxic tents. Illegal means include blood doping and the administration of EPO (erythropoietin). The ability to make EPO by genetic means has resulted in an increase in its availability and use, although it is probable that recent testing methods may have had some impact. Less widely used illegal methods include the use of artificial blood oxygen carriers (the so-called ‘blood substitutes’). In principle these molecules could enhance aerobic sports performance; however, they would be readily detectable in urine and blood tests. An alternative to increasing the blood oxygen content is to increase the amount of oxygen that haemoglobin can deliver. It is possible to do this by using compounds that right-shift the haemoglobin dissociation curve (e.g. RSR13). There is a compromise between improving oxygen delivery at the muscle and losing oxygen uptake at the lung and it is unclear whether these reagents would enhance the performance of elite athletes. However, given the proven success of blood doping and EPO, attempts to manipulate these pathways are likely to lead to an ongoing battle between the athlete and the drug testers.
