Supportive Argument

The scientific leading of the training process requires regular assessments of the exercise capacity and its dynamics. The concept of the method used for this application and carried out on a sample of Taekwondo athletes is trying to find the adequate solution in order to simultaneously meet two criteria: the attribute of significance of the motricity investigation and the feature of practicality in the sense of achieving an acceptable level of reliability and adequacy of the data while using a noninvasive device, which is also as less obtrusive as possible to the subjects. The progress rate of the anaerobic capacity and of the motric performance accomplished in competitions by the Taekwondo athletes tested by us are significantly correlated statistically with the indicators of the Myotest PRO survey, which results in a supportive argument for the efficiency of the procedure.

Oral D-ribose supplementation has been reported to increase adenine nucle-otide synthesis and exercise capacity in certain clinical populations. Theoretically, increasing adenine nucleotide availability may enhance high intensity exercise capacity. This study evaluated the potential ergogenic value of D-ribose supplementation on repetitive high-intensity exercise capacity in 19 trained males. Subjects were familiarized to the testing protocol and performed two practice-testing trials before pre-supplementation testing. Each test involved warming up for 5 min on a cycle ergometer and then performing two 30-s Wingate anaerobic sprint tests on a computerized cycle ergometer separated by 3 min of rest recovery. In the pre- and post-supplementation trials, blood samples were obtained at rest, immediately following the first and second sprints, and following 5 min of recovery from exercise. Subjects were then matched according to body mass and anaerobic capacity and assigned to ingest, in a randomized and double blind manner, capsules containing either 5 g of a dextrose placebo (P) or D-ribose (R) twice daily (10 g/d) for 5 d. Subjects then performed post-supplementation tests on the 6th day. Data were analyzed by ANOVA for repeated measures. Results revealed a significant interaction (p = .04) in total work output. Post hoc analysis revealed that work significantly declined (–18 ± 51 J) during the second post-supplementation sprint in the P group while being maintained in the R group (–0.0 ± 31 J). No significant interactions were observed in peak power, average power, torque, fatigue index, lactate, ammonia, glucose, or uric acid. Results indicate that oral ribose supplementation (10 g/d for 5 d) does not affect anaerobic exercise capacity or metabolic markers in trained subjects as evaluated in this study.

AbstractAmateur sport has significant influence on peoples’ physical activity and affects the prevalence of non-communicable diseases. The population of competing amateur athletes has not been sufficiently studied, and there is a huge gap between functional results of untrained individuals and professional athletes. The aim of the study was to evaluate the exercise capacity and chrono-tropic, inotropic capacity in amateur athletes with different training programmes, as assessed by cardiopulmonary exercise testing. In a longitudinal prospective study, 600 amateur athletes who performed high dynamic load sports, according to the Mitchell Classification of Sports, were assessed. The individuals underwent standard maximum cardiopulmonary exercise testing on the ISO certified Master screen CPX system. The exercise capacity was dependent on the training programme organisation, regularity and duration, but it was not dependent on age. During maximum work-rate, the functional parameters of the cardiorespiratory system and inotropic capacity were significantly dependent on duration of the training programme. Chronotropic and inotropic capacity, as well as cardiorespiratory adaptation were significantly higher for competing amateur athletes of both genders than for untrained individuals. The study showed that amateur athletes with a training programme 300 minutes per week had higher exercise capacity, which was based on the individually suitable training programme, and higher aerobic and anaerobic capacity. Regular pre-competition medical assessment of amateur athletes can be used to objectively evaluate their health condition, adaptation, cardiac risk and make changes in the athletes’ training programme.

High Intensity Interval

Engaging in regular exercise results in a range of physiological adaptations offering benefits for exercise capacity and health, independent of age, gender or the presence of chronic diseases. Accumulating evidence shows that lack of time is a major impediment to exercise, causing physical inactivity worldwide. This issue has resulted in momentum for interval training models known to elicit higher enjoyment and induce adaptations similar to or greater than moderate-intensity continuous training, despite a lower total exercise volume. Although there is no universal definition, high-intensity interval exercise is characterized by repeated short bursts of intense activity, performed with a “near maximal” or “all-out” effort corresponding to ≥90% of maximal oxygen uptake or >75% of maximal power, with periods of rest or low-intensity exercise. Research has indicated that high-intensity interval training induces numerous physiological adaptations that improve exercise capacity (maximal oxygen uptake, aerobic endurance, anaerobic capacity etc.) and metabolic health in both clinical and healthy (athletes, active and inactive individuals without any apparent disease or disorder) populations. In this paper, a brief history of high-intensity interval training is presented, based on the novel findings of some selected studies on exercise capacity and health, starting from the early 1920s to date. Further, an overview of the mechanisms underlying the physiological adaptations in response to high-intensity interval training is provided.

The Impact

Topicality. Running is one of the most popular activities in the world. Practicing this kind of sport is an important means of physical education, so it occupies one of the first places in the nature of motor actions. Short running race is the oldest type of athletic exercises included in modern athletics. It is characterized by the maximum intensity of the entire distance running at the anaerobic mode. Physical training of a runner for the short running race is divided into general and special. Special physical training of sprint athletes studying at higher education institutions is a multi-year and multifaceted process. It includes physical, tactical, technical and psychological training. The growth of sports results is possible due to the harmonious balance of all training aspects. The methods of intensification of special sprinters training will be effective and pedagogically expedient if it is based on reliable knowledge of the structural components of the athletes training, taking into account individual motor skills indicators. The research purpose is to substantiate the impact of training loads on the special physical training of students who specialize in 100 and 200 meters running races. The research tasks are studying and highlighting the researched problem analysis in domestic and foreign sources; determining the impact of training loads on the female students’ special physical training at sportsmanship improving classes. Methods of the research. Analysis and synthesis of scientific literature sources, dialogues, pedagogical observation, pedagogical experiment, methods of mathematical statistics. Results of the research. The success of sprinters training depends on the effectiveness of methods, organization and managemnt of the training process. The use of a significant number of special means of physical and functional training in the training process effectively affected the students physical fitness of the main group. In particular, a probable increase of 100 and 200 meters running results was established, which indicates the girls` anaerobic capacity development who are specialized in the short running race. The indicators of 30 meter flying start run, as well as 100 and 200 meters and shuttle running showed an increased results of female students of the main group. There is a slight increase in speed, coordination and anaerobic-aerobic capacity of female students of the control group. Such results are due to the use of larger number of anaerobic training modes. Conclusions. It is necessary to use a significant number of general and special tools for the formation of physical and functional fitness during the students’ educational and training process. In particular, for the female students` training in short running race, it is advisable to increase the training at anaerobic and anaerobic-aerobic modes, which will promote the development of speed, speed endurance and functionality improving.

1. In order to evaluate the influence of varying degrees of anaemia on exercise capacity and haemodynamic parameters, 13 patients on chronic intermittent haemodialysis with haemoglobin levels between 5.1 and 12.2 g/100 ml were subjected to an exhaustive exercise test. Measurements during bicycle ergometry consisted of O2 uptake at the anaerobic threshold and of maximum O2 uptake. Resting haemodynamic parameters such as cardiac index, heart rate, stroke volume index and blood pressure were assessed non-invasively in the 13 patients undergoing exercise and in an additional three patients. 2. O2 uptake at the anaerobic threshold as well as maximum peripheral O2 uptake were severely impaired and were positively correlated with haemoglobin concentration. The strongest correlation was found between the impairment of O2 uptake at maximum workload, as assessed by maximum O2 uptake/predicted maximum O2 uptake, and haemoglobin concentration. Haemodynamic alterations in the resting state consisted of a cardiac index in the upper normal range and did not correlate with the haemoglobin concentration. 3. We conclude from our study that exercise capacity in patients on chronic intermittent haemodialysis is severely impaired and that the impairment of aerobic and anaerobic capacity is significantly correlated with the severity of renal anaemia.

A relatively young Olympic discipline, judo is characterised by spectacularity, combative spirit and complexity in the execution of specific techniques. The technical training model and reaching the sports shape are the main objectives in the preparation of performance judo athletes. Maximal and supramaximal demands in modern competitions, which are determined by the specific biomechanics of technical actions, require the adaptation of athletes to supramaximal effort and the continuous increase of their exercise capacity. This paper aims to determine the relationship between the specific factors of aerobic and anaerobic exercise capacity in senior performance judo athletes participating in national and international competitions. The research subjects are performance and high-performance male and female athletes aged 19 to 21 years, members of the Romanian Judo Federation. To conduct the research, general and specific methods of assessing and developing aerobic and anaerobic exercise capacity are used. The assessment of subjects in the three training mesocycles was based on lactacidaemia, glycaemia and laboratory spectrophotometry as methods of determining their anaerobic adaptation. To assess their specific anaerobic capacity, methods of determining blood lactate and laboratory spectrophotometry are used. Aerobic capacity is determined by spirometry and digitised pulse oximetry methods. Maximum oxygen consumption, blood haemoglobin and pulse oxygen levels are graphically represented and interpreted, together with the comparative calorimetric and thermographic assessment of the tested subjects. The research findings highlight the importance of assessing aerobic and anaerobic exercise capacity in the training of performance judo athletes through modern assessment and analysis methods.

Mediterranean Fever

Background:Familial Mediterranean fever (FMF) is an auto-inflammatory disease commonly affects people from Mediterranean basin. It is characterized by acute self-limiting inflammatory attacks of serous membranes. The disease is commonly associated with musculoskeletal symptoms of lower extremities such as arthritis, exercise induced leg pain, as well as protracted febrile myalgia. The term of anaerobic exercise capacity describes the ability of performing quick and explosive tasks such as stair climbing and brisk walking. It is well known that anaerobic exercise capacity is closely related to functional status.Objectives:To assess the relationship between anaerobic exercise capacity and lower extremity functionality in patients with FMF.Methods:Twenty-eight FMF patients (57% female) were included in the study. Median age was 33.5 (IQR 25/75: 23.3/44.3) years, median body mass index was 24.3 (IQR 25/75: 21.0/27.8) kg/m2, median time since symptom onset was 20.0 (IQR 25/75: 11.5/24.5) years, median time since diagnosis was 10.0 (IQR 25/75: 3.75/17.5) years, and median colchicine dosage was 1.5 (IQR 25/75: 1.0/1.5) mg/day. Anaerobic exercise capacity was measured with Wingate Anaerobic Test by using a cycle ergometer. Peak power (watt/kg) and average power (watt/kg) were calculated. Stair climbing, standing from a chair, and walking were assessed by using 9-step stair climb test, 10-repetition chair stand test, and 6-minute walking distance, respectively. Spearman’s rank-order correlation test was used to analyse the relationships between anaerobic exercise capacity and lower extremity functional tests.Results:The results of the anaerobic exercise capacity and lower extremity functional test scores of patients with FMF were summarized in table 1. Moderate relationships were found between both peak and average anaerobic exercise capacities and lower extremity functional status tests (Table 1, p<0.05). Six-minute walking distance has the strongest association with both peak (rho: .672, p<0.001) and average (rho: .689, p<0.001) anaerobic exercise capacity.Table 1.Anaerobic exercise capacity scores and lower extremity functionality as well as the relationships between anaerobic capacity and functional tests in patient with familial Mediterranean fever.CharacteristicsMedian (IQR 25/75)(n:28)The correlation results, rho, p valuesPeak Power(watt/kg)Average Power (watt/kg)9-step stair climb test (seconds)5.7 (5.1/6.4)-.590*-.648*p:0.001p: 0.00110-repetition chair stand test (seconds)16.6 (13.7/18.7)-.493*-.476*p:0.008p:0.0106-minute walking distance (meters)594.1 (551.1/643.3).672*.689*p<0.001p<0.001Peak power (watt/kg)5.8 (4.1/7.9)Average power (watt/kg)4.6 (3.1/5.9)IQR 25/75: Interquartile range between 25th and 75th percentiles; kg: kilograms, *Spearman’s rank-order correlation test, p<0.05.Conclusion:According to our results, anaerobic exercise capacity is related to lower extremity functional status in patients with FMF. Improving anaerobic capacity by using optimal rehabilitation programs including speed and agility exercises may help to improve anaerobic exercise capacity, and consequently lower extremity functionality in those patients.Disclosure of Interests:None declared

Abstract Background Nutritional supplementation is commonly used by athletes to improve their exercise performance. Previous studies demonstrated that citrus flavonoid extract (CFE) supplementation may be an effective strategy to improve exercise performance in male athletes. Yet, no conclusive research has been performed to investigate the effect of chronic CFE supplementation on high-intensity exercise performance under anaerobic conditions. Therefore, the aim of the study was to assess whether CFE supplementation in daily dosages of 400 and 500 mg for a period of 4 and 8 weeks improves anaerobic exercise capacity. Methods A randomized, double-blind, placebo controlled, parallel clinical study was conducted in 92 moderately trained healthy men and women. Subjects were randomized to receive 400 mg of CFE (n = 30), 500 mg of CFE (n = 31) or placebo (n = 31) daily, for 8 consecutive weeks. The Wingate anaerobic test was used to assess anaerobic exercise capacity and power output at baseline, after 4 weeks and after 8 weeks. Results After 4 weeks supplementation, average power output significantly increased in the 400 mg group (Estimated difference [ED] = 38.2 W [18.0, 58.3]; p < 0.001; effect size [ES] = 0.27) and in the 500 mg group (ED = 21.2 W [0.91, 41.4]; p = 0.041; ES = 0.15) compared to placebo. The 5 s peak power output was also increased in the 400 mg group (ED = 53.6 [9.96, 97.2]; p = 0.017; ES = 0.25) after 4 weeks compared to placebo. After 8 weeks of supplementation, average power output was significantly improved in the group receiving 400 mg of CFE (ED = 31.6 [8.33, 54.8]; p = 0.008; ES = 0.22) compared to placebo. Conclusion These results demonstrate that CFE supplementation improved anaerobic capacity and peak power during high intensity exercise in moderately trained individuals. Further research is needed to identify the underlying mechanisms that are affected by CFE supplementation. Trial registration ClinicalTrials.gov (NCT03044444). Registered 7 February 2017
