Intensity Distribution of Collegiate Cross-Country Competitions.

The primary purpose of the current investigation was to perform an intensity distribution analysis of a collegiate cross-country (CC) competition, with a secondary purpose to compare race times (RT) with modeled performance times (MPT). Participants completed an incremental treadmill test to determine gas exchange threshold (GET), while the three-minute all-out test was conducted on a 400 m outdoor track to determine critical velocity (CV) and D prime (D'). GET and CV were used as physiological markers for the intensity zones based on heart rate (HR) and running velocity (RV), while CV and D' were used to determine modeled performance times. Participants wore a Global Positioning System (GPS) watch and heart rate (HR) monitor during competition races. Statistically, less time was spent in HR Zone 1 (12.1% ± 13.7%) compared to Zones 2 (37.6% ± 30.2%) and 3 (50.3% ± 33.7%), while a statically greater amount of time was spent in RV Zone 2 (75.0% ± 20.7%) compared to Zones 1 (8.4% ± 14.0%) and 3 (16.7% ± 19.1%). RTs (1499.5 ± 248.5 seconds (s)) were statistically slower compared to MPTs (1359.6 ± 192.7 s). The observed differences in time spent in each zone are speculated to be related to the influence of environmental conditions on internal metrics and difference in the kinetics of HR and running velocity. Differences in RTs and MPTs are likely due to the MPT equation modeling all-out performance and not considering race strategies.

Competitive Cross-Country Skiers Have Longer Time to Exhaustion Than Recreational Cross-Country Skiers During Intermittent Work Intervals Normalized to Their Maximal Aerobic Power.

To investigate differences in time to exhaustion (TTE), O2 uptake (V˙O2), and accumulated O2 deficit (O2def) between competitive and recreational cross-country (XC) skiers during an intermittent-interval protocol standardized for maximal aerobic power (MAP). Twelve competitive (maximal V˙O2 [V˙O2max]=76.5±3.8 mL·kg-1·min-1) and 10 recreational (V˙O2max=63.5±6.3 mL·kg-1·min-1) male XC skiers participated. All tests were performed on a rollerski treadmill in the V2 ski-skating technique. To quantify MAP and maximal accumulated oxygen deficit(MAOD), the skiers performed a steady-state submaximal test followed by a 1000-m time trial. After a 60-minute break, TTE, V˙O2, and accumulated O2def were measured during an intermittent-interval protocol (40-s work and 20-s recovery), which was individually tailored to 120% and 60% of each subject's MAP. During the 1000-m time trial, the competitive skiers had 21% (95% CI, 12%-30%) shorter finish time and 24% (95% CI, 14%-34%) higher MAP (all P < .01) than the recreational skiers. No difference was observed in relative exercise intensity (average power/MAP; P = .28), MAOD (P = .18), or fractional utilization of V˙O2max. During the intermittent-interval protocol, the competitive skiers had 34% (95% CI, 3%-65%) longer TTE (P = .03) and accumulated 61% (95% CI, 27%-95%) more O2def (P = .001) than the recreational skiers during work phases. Competitive XC skiers have longer TTE and accumulate more O2def than recreational XC skiers during an intermittent-interval protocol at similar intensity relative to MAP. This implies that performance in intermittent endurance sports is related to the ability to repeatedly recharge fractions of MAOD.

International development strategy of a fintech company: key aspects and challenges

In the conditions of globalization of the financial services and financial systems market, an urgent issue for a fintech company is the problem of forming and implementing an international development strategy, considering the most critical aspects and challenges. Specific aspects include regulatory constraints, cross-country competition, technological innovation, adaptation to local financial systems, strengthening cyber security, and building strategic partnerships. Developing an effective action plan is a crucial factor for the successful global development of a fintech company. The article examines the main aspects of the international development strategy of fintech companies and highlights the main challenges they face. It was determined that one of the most critical aspects in this context is considering the differences in regulatory acts in different countries and their impact on the strategic planning of fintech companies. Another vital aspect is technological innovation: fintech companies must not only have technological solutions but also be ready to implement new technologies, such as artificial intelligence, blockchain, etc. All this allows you to create competitive advantages and satisfy the ever-increasing demand for fast, convenient, secure financial services. It is justified that, first, companies should study the political, economic, and socio-cultural aspects of each country in which they plan to work since the presence of different regulations and cultural features can significantly affect the strategy's success. Challenges also include the need to manage cyber security. Based on a comprehensive approach, considering the peculiarities of the global financial market, the main elements of the strategy of international development of a fintech company are proposed.

Environmental Tax Convergence and Interdependence in the European Union

This paper empirically analyzes the convergence and interdependence of environmental taxes in Europe from 1998 to 2018. Our results evidence a lack of European integration and reveal a group of converging countries characterized by a lowering tax burden. Moreover, a subsequent spatial regression analysis supports that the converging countries exhibit a significantly greater sensibility to the neighboring environmental tax policies, compatible with some degree of cross-country tax competition.

Вопросы эмиссии и обращения цифрового рубля

Objective: to analyze the prerequisites for the issue of the digital ruble; to study the main features of the issue and circulation of the digital ruble; to clarify the consequences of the introduction of the digital ruble for the banking system and the economy as a whole.Methods: comparative analysis of approaches to the implementation of the digital currency issue project in different countries, modeling of the project results in the conditions of the modern Russian economy.Results: the article shows that the transition to the issuance of digital currencies of central banks, and the digital ruble in particular, is a logical result of the evolution of the monetary system based on commercial banks and technological innovations introduced by modern cryptographic technologies. A component-by-component analysis of the digital ruble emission process is presented. The main directions of using the digital ruble are considered, including payment turnover and monetary policy. It is noted that the issue of digital rubles will lead to a serious transformation of the modern model of the monetary component and, as a result, the financial system as a whole. It is concluded that the role of banks in the new model of money circulation is significantly reduced and that the cross-country competition in the field of digital currencies and stablecoins is increasing. Scientific novelty: the work is devoted to the study of the conditions and results of the introduction of digital currency in the Russian economy, which became an urgent problem in connection with the publication of the Bank of Russia report “On the digital ruble”. Thus, the scientific novelty of the study stems from the novelty of the problem posed and the actual absence of earlier works on this topic in Russia.Practical significance: the results of the study can be applied in the digital ruble design and pilot testing of its use in 2021-2022.

Performance and Health Decrements Associated With Relative Energy Deficiency in Sport for Division I Women Athletes During a Collegiate Cross-Country Season: A Case Series.

The purpose of this case series was to evaluate the presence of low Energy Availability (EA) and its impact on components of Relative Energy Deficiency in Sport (RED-S) in a population of female collegiate runners. Seven female NCAA Division I athletes (age: 22.3 ± 1.5 yrs; height: 169.7 ± 5.7 cm; weight: 58.3 ± 4.1 kg) were tracked from August until February, covering the beginning (Pre XC), end (Post XC) of their competitive cross country season, and beginning of the following track season (Pre Track). The athletes were assessed for female athlete triad (Triad) risk, energy availability, body composition, resting metabolic rate (RMR), nutritional intake, and blood markers (including vitamin D, ferritin, and triiodothyronine (T3)). From Pre XC to Post XC there were no significant differences in body mass, fat free mass or body fat percentage. At Pre XC, mean EA was 31.6 ± 13.3 kcal/kg FFM∙d-1. From Post XC to Pre Track, there was a significant increase in body mass (59.1 ± 5.1 to 60.6 ± 5.7 kg, p<0.001,d=0.27). From Post XC to Pre Track, there was a significant increase in RMR (1466 ± 123.6 to 1614.6 ± 89.1 kcal·d-1, p<0.001,d=2.6). For 25(OH) vitamin D, there was a significant reduction from Pre XC to Post XC (44.1 ± 10.6 vs 39.5 ± 12.2 ng·mL-1, p=0.047,d=-0.4), and a significant increase from Post XC to Pre Track (39.5 ± 12.2 vs. 48.1 ± 10.4 ng·mL-1, p=0.014,d=0.75). For ferritin, there was a trend towards a decrease from Pre XC to Post XC (24.2 ± 13.2 vs. 15.7 ± 8.8 ng·mL-1, p=0.07, d=-0.75), as well as a trend toward an increase from Post XC to Pre Track (15.7 ± 8.8 vs. 34.1 ± 18.0 ng·mL-1, p=0.08, d=1.3). No differences in T3 were observed across time points. Average Triad risk score was 2.3 ± 1.4. Notably, 5 of 7 athletes met criteria for moderate risk. Despite many athletes meeting criteria for low EA and having elevated Triad risk assessment scores, most were able to maintain body mass and RMR. One athlete suffered severe performance decline and a reduced RMR. Surprisingly, she was the only athlete above the recommended value for ferritin. Following increased nutritional intake and reduced training volume, her performance and RMR recovered. Changes in body mass and body composition were not indicative of the presence of other concerns associated with RED-S. This exploratory work serves as a guide for future, larger studies for tracking athletes, using RMR and nutritional biomarkers to assess RED-S.

Three km Track Time Trial Performance Changes after HIIT in Competitive Cross-Country Skiers

Background: Limited research surrounding sex differences in fatigue and performance after high intensity interval training (HIIT) exists in the field setting. While lab-based protocols provide a controlled environment, physiological mechanisms of fatigue and performance response in competitive athletes are best measured by time-trial (TT). Few studies, however, have investigated fatigue in TT performance while controlling for the menstrual cycle (MC). Objective: The study investigated the influence of sex and MC phase on 3km track TT performance after a HIIT session in Competitive Cross Country (XC) skiers. Methods: A quasi-experimental design was employed and athletes over the age of 16 years (30F, 9M), were recruited from across Canada and completed 3 days of testing/training: a 3km track TT on Day 1 and Day 3; and a HIIT session (4-8x, 800m) on Day 2. MC phase was verified by ovulation testing and salivary hormone samples; athletes were classified as either “Low Hormone” or “High Hormone” for analysis. Results: An overall improvement in performance from pre- to post-HIIT TTs occurred (p&lt;0.01). No significant differences in TT performance after HIIT were observed between sexes (p=0.16) or MC phase (p=0.26). Conclusion: These results indicate that competitive XC skiers will likely experience an improvement in TT performance after a bout of HIIT. Coaches and athletes should plan their workouts prior to testing accordingly to maximize TT performance. These results also suggest that no special adjustments need to be considered for differences in performance after HIIT between sexes and MC phase, although further studies with a greater sample size and repeated testing are warranted.

FEDERAL AND REGIONAL CONTEXT OF THE HIGHER EDUCATION IN RUSSIA

In the face of increasing cross-country competition, the strategic role of higher education and science is steadily increasing. Russia largely copies Western standards in the field of science and education, having nothing to do with the development of these standards. As a result, the Russian Federation is on the periphery of the world intellectual development. The situation is exacerbated by changes in Russian higher education. In the 21st century, the higher education of Russia is characterized by the division of universities into federal and regional, which affects funding, the level of autonomy in the conduct of educational and scientific activities and other characteristics. The “nomenclature” approach to highereducation institutions of the Russian Federation turns many regional universities into noncompetitive. Probably, the lack of conditions for equal inter-university competition dramatically reduces the interest for private business investment in both federal and regional universities. The article analyzes, in application to the Russian Federation, three models of the development of modern higher education, common in the world. It is concluded that the numerous deformations of modern Russian society are transferred to higher education. Therefore, education reforms are impossible without major changes in society and without taking into account the fact that modern Russian universities reproduce the diversity of socio-economic relations.

EU funds, state capacity and the development of transnational industrial policies in Europe’s Eastern periphery

Many have claimed that in the dependent market economies of Central and Eastern Europe industrial policy has been reduced to incentives to foreign investors – a feature accentuated by their loss of policy space through integration into the European single market. In this paper, we offer an alternative view by arguing that the European Union (EU) has in fact made it possible for its members to recover a degree of policy space lost to economic and regulatory integration. The EU does this through transnational industrial policy, which is the combination of its competition and cohesion policies. The former limits cross-country competition for capital; the latter provides additional resources to support a more inclusive industrial policy benefiting small and medium enterprises (SMEs). However, effective utilization of transnational industrial policy depends on domestic state capacities. We demonstrate this by comparing the distribution of EU funds to automotive firms in Poland and Romania. In Poland, efforts to create institutions that promote SMEs have resulted in a more balanced distribution of EU resources, while in Romania a weak and unstable institutional environment led to their greater concentration, thereby reducing European funds to another source of rents for the most powerful firms.

Effects of NCAA Division I Cross-Country Training on Serum Ferritin, Monocytes, TNF-α and DKK1 (P18-126-19)

ObjectivesInflammatory cytokine and immune cell production is modulated by iron status including storage measured by ferritin levels. Cross-country athletes have an elevated risk of iron depletion and stress fractures; the effects of a competitive season on inflammation, iron stores, and bone biomarkers have yet to be elucidated. The purpose of this study is to determine the influence of one season of NCAA Division I (D-I) cross-country competition has on TNF-α, serum ferritin (sFer), complete blood count (CBC), and various bone biomarkers to identify potential relationships. MethodsTwelve D-I cross-country athletes, ages 19 to 25 years old, were followed for one year. Blood was collected at the beginning of each season and analyzed for CBC and sFer levels through enzymatic spectrophotometry. TNF-α, OPG, OPN, DKK1, SOST, PTH, FGF23, Insulin, and Leptin were measured through Luminex® MAGPIX® multiplex assays. Paired-samples t-test compared the 2017 preseason and 2018 preseason baselines, while Pearson correlations included both seasons. Statistical analyses were performed using IBM® SPSS Statistics 25 software. ResultsTNF-α levels increased significantly from 2017 to 2018 (9.5 ± 4.6 vs. 12.2 ± 4.9 pg/mL, P = 0.005) as well as DKK1 (544.4 ± 223.6 vs. 1167.0 ± 212.1 pg/mL, P < 0.001), while % Monocytes decreased significantly from 2017 to 2018 (10.7 ± 2.6 vs. 8.6 ± 1.9%, P = 0.003). sFer showed to have a moderate positive-correlation with TNF-α and OPG (r = 0.619, P = 0.002; r = 0.640, P = 0.001) throughout both preseason intervals. ConclusionsGiven TNF-α has shown to induce DKK1, both bone mineral density and bone biomarkers of the cross-country athlete needs to be continually assessed throughout multiple stages of their competitive season to insure proper bone health. Further investigation is needed into the potential causes for the increases of TNF-α and DKK1 observed in cross-country athletes.

China strategic initiative “One Belt, One Road” (OBOR) as tool for development and algorithm for effect on Central Asia countries

The concept of Central Eurasian Region is introduced and grounded; the role of the Region in geopolitical and geo-economic entities of world leading actors is considered. Multiple interests of remote and adjacent to Central Asia countries involved in integration/disintegration processes are identified. Probable effects of the initiative “One Belt, One Road” (OBOR) on the territory (through which transnational transport and logistics routes will pass) are discussed. The emphasis is made on mountainous inland landscapes and their ecological value for national communities and states. Authors describe major risks associated with the proposed mega-project, which accounts for China interests. The danger of receiving most dividends by few stakeholders and possible negative consequences for local population are considered. We propose the methods for optimal development of this ultra-continental region. Here, a coordinated development of numerous spheres is required that will contribute to progressive movement forward and prevent the extreme interregional and cross-country competition under limited investments and resources. Transboundary projects (“Tashkent-Shymkent and Rubtsovsk-Semey industrial hubs”) can be realized along with OBOR in comply with own interests. The need for Russia and adjacent countries cooperation with further establishment of a specific economic-political union aimed to improve their position on the world stage is specified.

The manufacturing sector: Still an anchor for pattern bargaining within and across countries?

This article investigates the development of collective wage bargaining systems in manufacturing in five countries: Denmark, Finland, Germany, Norway and Sweden. We illustrate the responses of collective actors to two key challenges: first, increased cross-country competition between Northern European companies operating within the same high-value/high-cost segment of the market; second, the competitive pressures resulting from increased east-north integration. Our analytical framework sets out different forms and outcomes of institutional change, with a focus on how the responses of collective actors to these two challenges shaped the development of wage bargaining systems.

Physiological Demands of Elite Cross-Country Skiing During a Real Competition.

The aim of this study was to assess different physiological variables before and after a 5-km (women) and 10-km (men) cross-country skiing competition to determine potential mechanisms of fatigue. Fourteen elite-level skiers competed in an official cross-country skiing competition using the classical style (9 men and 5 women). Instantaneous skiing velocity was measured during the race by means of 15-Hz global positioning system devices. Before and after the race, a sample of venous blood was obtained to assess changes in blood lactate and serum electrolyte and myoglobin concentrations. Prerace to postrace changes in blood oxygen saturation, forced vital capacity during a spirometry test, jump height during a countermovement jump, and handgrip force were also measured. Mean race speed was 15.8 ± 2.5 and 15.4 ± 1.5 km·h, whereas mean heart rate was 171 ± 6 and 177 ± 3 b·min for men and women, respectively. There were no significant prerace to postrace changes in jump height, handgrip force, and forced vital capacity in men and women. Blood oxygen saturation was reduced from prerace to postrace in men (95.9 ± 2.1% to 93.1 ± 2.3%, p = 0.02) and women (97.8 ± 1.1% to 92.4 ± 2.1%, p < 0.01), whereas blood lactate concentration increased at the end of the race in men (1.4 ± 0.5 to 4.9 ± 2.1 mmol·L, p < 0.01) and women (1.9 ± 0.1 to 6.9 ± 3.2 mmol·L, p < 0.01). After the race, blood markers of muscle damage were at low concentrations, whereas serum electrolytes remained unchanged. Fatigue in 5- and 10-km cross-country skiing competitions was related to a reduced blood oxygen carrying capacity and presumably increased muscle and blood acidosis, whereas the influence of exercise-induced muscle damage on fatigue was minor.

The Evolution of Champion Cross-Country-Skier Training: From Lumberjacks to Professional Athletes.

Competitive cross-country (XC) skiing has traditions extending back to the mid-19th century and was included as a men's event in the first Winter Games in 1924. Since then, tremendous improvements in equipment, track preparation, and knowledge about training have prompted greater increases in XC-skiing speeds than in any other Olympic sport. In response, this commentary focuses on how the training of successful XC skiers has evolved, with interviews and training data from surviving Norwegian world and Olympic XC champions as primary sources. Before 1970, most male champion XC skiers were lumberjacks who ran or skied long distances to and from felling areas while working long days in the woods. In addition, they trained as much as possible, with increased intensity during the autumn, while less work but more ski-specific training and competitions were done during the winter. Until the 1970s, few XC skiers were women, whom coaches believed tolerated less training than men did. Today's XC skiers are less physically active, but the influence of both science and the systematic approaches of former athletes and coaches have gradually taught XC skiers to adopt smarter, more goal-oriented training practices. Although the very high VO2max of world-class XC skiers has remained the same since the 1960s, new events in modern XC skiing have additionally required superior upper-body power, high-speed techniques, and tactical flexibility. These elements also emerge in the training of today's best skiers; women's physiological capacities and training routines especially seem to have improved dramatically.

Mineral Density Levels in Male and Female Collegiate Cross Country Runners: Is there Reason for Concern?

Introduction: The results of several recent studies have questioned the consequences of high levels of running on bone mineral density (BMD). Elite endurance athletes experience high physiological stress which may negatively impact bone health. Thus, the purpose of this study was to examine the change in BMD in male and female Division I collegiate runners during a competitive Cross Country (CC) season. Methods: T wenty-three (1 1 male and 12 female) Division I collegiate CC runners (ages 18-22 year) were recruited for this study. Total/regional BMD and body composition was determined using dual x-ray absorptiometry. Caloric intake and running mileage was obtained from self-reported diet and training logs. All measures were performed prior to the start (pre) and immediately following (post) a three month collegiate CC season. Results: Males did not demonstrate any significant changes in body composition from pre-post CC whereas females had a significant increase (2.7 ± 1.7 lbs or 2.1%) in total mass, with non-significant increases in fat free and fat mass. From pre- post CC, males did not have any significant changes in bone density whereas females had a statistically significant decrease in bone density of lumbar vertebrae. While no other changes in total or regional BMD were observed, ~ 50% of the both male and female athletes tested in this study had total BMD lower than the age-based reference value. Conclusion: The results of this study suggest that a single competitive CC season can result in a decrease in the lumbar spine BMD in female collegiate distance runners. Moreover, this study revealed that a large percentage (~ 50%) of both male and female distance runners had lower than age-adjusted normal BMD level, raising concerns about long-term bone health in these athletes. Verification of these findings in a larger more diverse population of young athletes is warranted to determine the long term consequences of distance running on bone health.

Lower Extremity Biomechanical Changes During a Collegiate Cross Country Season

Abnormal biomechanics increase the risk of sustaining noncontact and overuse lower extremity (LE) injuries. Acute bouts of fatiguing exercise alter LE biomechanics and can increase the risk of injury. Currently, the cumulative effects of repetitive fatiguing exercise bouts on biomechanics are unknown. PURPOSE: To determine the effects of repetitive fatiguing exercise (endurance running) on LE biomechanics. METHODS: Movement compensations (errors) during an overhead (OHS) and single leg squat (SLS) were assessed in thirty-five NCAA division I cross country athletes (males = 19, females = 16). Testing was completed prior to and midway through the competitive cross country season. The athletes were not acutely fatigued during testing. Movement errors were identified by a certified athletic trainer who has experience evaluating the OHS and SLS. Errors included: feet flattening/turning out, heels lifting off the ground, knee valgus/varus motion, knee flexion angle <60°, asymmetrical hip/weight shift, hip hike/drop, low back arching/rounding, uncontrolled trunk motion, arms falling forward, and loss of balance. Differences in total errors and the proportions of errors at pre- and mid-season were assessed using Wilcoxon signed rank and McNemar’s exact tests. RESULTS: Differences for total errors during the SLS (pre = 4.71±1.45, mid = 3.34±0.94; p<0.01) and the proportion of errors during the SLS for asymmetrical hip shift (pre = 0.97, mid = 0.66; p<0.01) and uncontrolled trunk motion (pre = 0.74, mid = 0.43; p=0.02) from pre- to mid-season were observed. The proportions of SLS hip hike/drop (pre = 0.71, mid = 0.46; p=0.06), OHS asymmetrical weight shift (pre = 0.74, mid = 0.51; p=0.06), and OHS knee varus motion (pre = 0.23, mid = 0.09; p=0.06) were near significance. No other differences existed between pre- and mid-season. CONCLUSIONS: The total number and proportions of movement errors between pre- and mid-season assessments improved; especially errors specific to hip motion. The SLS is more physically demanding than the OHS, and may be more sensitive to detecting alterations in movement errors over a sport season. Repetitive fatiguing exercise alters LE biomechanics; these alterations may be different than those caused by acute exercise fatigue. Also, the effects of these alterations on injury risk remain unknown.

Repeated double-poling sprint training in hypoxia by competitive cross-country skiers.

Repeated-sprint training in hypoxia (RSH) was recently shown to improve repeated-sprint ability (RSA) in cycling. This phenomenon is likely to reflect fiber type-dependent, compensatory vasodilation, and therefore, our hypothesis was that RSH is even more beneficial for activities involving upper body muscles, such as double poling during cross-country skiing. In a double-blinded fashion, 17 competitive cross-country skiers performed six sessions of repeated sprints (each consisting of four sets of five 10-s sprints, with 20-s intervals of recovery) either in normoxia (RSN, 300 m; FiO2, 20.9%; n = 8) or normobaric hypoxia (RSH, 3000 m; FiO2, 13.8 %; n = 9). Before (pre) and after (post) training, performance was evaluated with an RSA test (10-s all-out sprints-20-s recovery, until peak power output declined by 30%) and a simulated team sprint (team sprint, 3 × 3-min all-out with 3-min rest) on a double-poling ergometer. Triceps brachii oxygenation was measured by near-infrared spectroscopy. From pretraining to posttraining, peak power output in the RSA was increased (P < 0.01) to the same extent (29% ± 13% vs 26% ± 18%, nonsignificant) in RSH and in RSN whereas the number of sprints performed was enhanced in RSH (10.9 ± 5.2 vs 17.1 ± 6.8, P < 0.01) but not in RSN (11.6 ± 5.3 vs 11.7 ± 4.3, nonsignificant). In addition, the amplitude in total hemoglobin variations during sprints throughout RSA rose more in RSH (P < 0.01). Similarly, the average power output during all team sprints improved by 11% ± 9% in RSH and 15% ± 7% in RSN. Our findings reveal greater improvement in the performance of repeated double-poling sprints, together with larger variations in the perfusion of upper body muscles in RSH compared with those in RSN.

Intercollegiate Cross Country Competition: Effects of Warm-up and Racing on Salivary Levels of Cortisol and Testosterone

Grossly Inadequate: Feminist Figurations, Neo-liberal Governmentality, and Comic Culture

Let me tell you a little story. When I was about 10, encouraged by my parents, I signed up for a cross-country skiing competition.1 The day of the event came, I heard the starting signal, and off I...
