Purpose. Different forms of cycling require the use of different abilities and skills. The aim of this paper was to attempt to identify differences in the directions and dynamics of the body’s adaption to training in road (ROAD) and mountain (MTB) cyclists. Methods. Research was performed on a group of competitive road (n = 25) and mountain (n = 25) cyclists, mean age 16.96 ± 0.78 years presenting maximal oxygen uptake values of 4.45 ± 0.47 L/min-1. Body composition and physiological and biochemical parameters at rest, during exercise, and during restitution (cool down) were determined. Exercise was performed on a cycle ergometer in the form of a progressive load test. Analysis of the results included cluster analysis and basic statistical methods. Results. Cluster analysis indicated that the amount of work performed during the progressive load test was a universal indicator of physical fitness. The level of base excess (BE) in the 3rd min of restitution had a large influence on the remaining parameters in both groups. Training adaptation in MTB were manifested through increased values of maximum heart rate, blood oxygen saturation, oxygen partial pressure, and lactate and BE levels in the blood, as well as a reduction in blood pH and body mass. Conversely, in ROAD, adaptation to effort was evidenced by increased maximum values of oxygen uptake, minute ventilation, cardiac output and the rate of carbon dioxide elimination as well as an increase in hematocrit count and lean body mass. Conclusions. Adaptation to training by road cyclists is primarily evident in the development of aerobic capacity. Mountain biking induces adaptive changes in the development of anaerobic capacity by increasing the buffer capacity of the blood and muscles, as well as the development of the oxygen transportation system.

Purpose. The aim of this study was to investigate the influence of 8-week-long interval training (targeting glycolytic capacity) on selected markers of physical fitness in amateur long-distance runners. Methods. The study involved 17 amateur long-distance runners randomly divided into an experimental (n = 8) and control (n = 9) group. The control group performed three or four continuous training sessions per week whereas the experimental group performed two interval running training sessions and one continuous running training session. A graded treadmill exercise test and the 12-min Cooper test were performed pre- and post-training. Results. O2max and the rate of recovery increased in the experimental group. Relative oxygen uptake, minute ventilation, and heart rate speed decreased in low- (6 km/h) and medium-intensity (12 km/h) running. Conclusions. Both training modalities showed similar results. However, the significant differences in training volume (4-8 min interval training vs. 40-150 min continuous training) indicates that the modalities targeting glycolytic capacity may be more efficient for amateur runners prepare for long-distance events.

Purpose. Assessment of circulatory and respiratory response to separate exercise tests under the condition of increasing the volume of added respiratory dead space by 200 cm3 at a time. Basic procedures. Human volunteers performed 10 minutes of cycle ergometer exercise on nine occasions, with the increasing volume of added dead space at the intensity of 100 Watt. Main findings. The ventilatory parameters tended to increase proportionally to the volume of added dead space. VE, VT, RF increased from 29.35 ± 4.01; 1.62 ± 0.29; 18.52 ± 4.76 (at 0 cm3) to 62.42 ± 8.33; 2.43 ± 0.24; 26.00 ± 5.51 (at 1600 cm3), respectively. There were not any significant differences among the post-exercise values of LA, pO2, HCO-3act, BE(B) and HR. All the values of O2 SAT ranged between 94.87 ± 1.19 and 95.72 ± 0.76, and the values of HCO-3std between 25.23 ± 1.36 and 24.00 ± 0.78. The post-exercise values of pH decreased, and pCO2 increased proportionally to the volume of added dead space, from 7.41 ± 0.01 (at 0 cm3) to 7.33 ± 0.03 (at 1600 cm3) and from 40.89 ± 2.27 (at 0 cm3) to 51.13 ± 3.39 (at 1600 cm3), respectively. Conclusions. Added respiratory dead space evokes: increase in pulmonary ventilation, mainly in tidal volume; increase in arterial carbon dioxide pressure and decrease in pH, proportionally to the increase in dead space volume. Added dead space neither evokes hypoxemia nor intensifies anaerobic reproduction of ATP.

Purpose. The purpose of this research was to determine the relationship between a tennis players' technical abilities and their capacity evaluated in both a laboratory and on the tennis court. Basic procedures. Twelve tennis players participated in the study. The anaerobic capacity test (Wingate) and the progressive test were performed on a Monark E 895 cycloergometer. The aerobic and anaerobic capacities were evaluated in the laboratory. The Weber capacity test was performed on a tennis court. Main findings. The research did not reveal any significant correlation between the Wingate's mechanical parameters and the physiological parameters of the Weber test. A correlation of the maximal oxygen uptake with stroke precision on a tennis court can be observed. The research found that the maximal power output (Pmax) and total work (Wtot) found in the laboratory is related to the stroke precision on a tennis court. Conclusions. The results may suggest that both tests can be applied in the assessment of capacity and the effects of training. From the results of the laboratory and on-court tests, it is possible to specify a player's semi-specific endurance.

Purpose. In most circumstances it is possible to provide the precise estimation of force and weight by means of kinesthetic differentiation. In some conditions, like physical effort or fatigue, kinesthetic differentiation can become reduced. The kinesthetic differentiation capacity can be expressed as repeatability of muscular contraction force or movement. The present study investigates the direction of changes in kinesthetic differentiation of force applied by both arms during elbow flexion and extension before and after exercise. Basic procedures. The study sample consisted of 23 cyclists (mean ± SD) aged 18.1 ± 1.8 years, 17 rowers aged 18.1 ± 1.8 years, and a control group consisting of 32 subjects aged 21.3 ± 1.3 years. All subjects performed a progressive exercise test. Kinesthetic differentiation was measured as the repeatability of force applied during elbow flexion and extension. Main findings. The results obtained confirm that kinesthetic differentiation in both arms after exercise improved by means of elbow extension. Further research can contribute to the development of ways of control of adaptation changes in the central nervous system and the locomotor system on a general level, since the studies so far have described either local changes, e.g. EMG, or provided specific data related to typical patterns of activity in a given sport. Conclusions. The proposed method allows identification of effects of intense exercise on the kinesthetic differentiation capacity on a more general level.

The aim of our 10-week-long experiment was to investigate the impact of training with additional dead space (DS) on spirometry and exercise respiration. Respiratory muscle training is applied to the development exercise capacity. Twenty cyclists were assigned to two groups: the experimental (E) and the control (C). All of them carried on with their initial training programme. During endurance trainings (twice per week) group E used additional DS (1000 cm3). Immediatelly before and after the experiment each participant was submitted to a spirometry and a continuous test. The spirometry test measured peak inspiratory (PIF) and expiratory (PEF) flows, forced expiratory volume in one second (FEV1) and forced vital capacity (FVC). The continuous test measured tidal volume (TV), respiratory frequency (RF), along with inspiration and expiration times. Our experiment demonstrated TV increase and RF decrease in both groups. In addition, the TV value was significantly higher in group E than in C. The PIF value also increased significantly, PEF and FEV1 upward trend was observed in group E only. We concluded the additional respiratory DS used in the experimental group provoked an increase of airflow observed in the spirometry tests at rest and during intensive aerobic exercise.

Purpose. The aim of this study was to evaluate the impact of training with added respiratory dead space volume (ARDSV) on changes in a breathing pattern and cycling efficiency. Methods. Twenty road cyclists were equally divided into an experimental (E) and control (C) group. All of them were involved in a training program that included endurance training (at moderate intensity) and interval training (at maximal intensity). During semi-weekly endurance training, ARDSV (1000cm3 tube) was introduced in the experimental group. Respiratory parameters, including, among others, oxygen uptake (VO2), carbon dioxide excretion (VCO2), end-tidal partial pressure of carbon dioxide (PETCO2), pulmonary ventilation (VE), tidal volume (TV) and total work done during the tests (W), were measured before and after the experiment by a progressive and continuous test. Results. Higher PETCO2 and TV in both groups during the progressive and continuous tests were observed. VCO2 increased in group E during continuous test, while for group C only in the first four minutes of the test. VO2 and VE increased only in group E during submaximal and maximal exercise. Total work increased during the continuous test in both groups (significantly higher in group C than E). However, total work during the progressive test increased only in group E. Conclusions. Training with ARDSV improved exercise capacity at maximal effort and was associated with an increase in maximal oxygen uptake. On the other hand, this type of training lead to a decrease in cycling efficiency, reducing in effect the benefits associated with an increase in VO2max and reducing the ability to perform submaximal effort.

The aim of the study was to asses the influence of the type of rest on football players’ ability to repeat a phosphagen exercise. Twelve football players from the Polish third league were involved in the study and were subjected to a maximum power test on a cycloergometer. Respiratory parameters, lactic acid concentration in capillary blood and acid-base balance parameters were registered before, during and after the test. The test was carried out twice. During the first test the subjects used an active rest break (A) and during the second one they used a passive rest break (B). In part A the quantity of relative work was 87.61 ±9.25 J/kg and in part B it was 78.5 ±6.58 J/kg (p = 0.012). In test A during exertion and during restitution (4th minute) we registered higher values of the respiratory parameters (Rf, VE, VO2, VO2/kg). Our conclusion is that passive rest should be used when the objective is the fastest resynthesis of PCr and ATP. An active rest break should be used when the goal is to remove the accumulated LA as soon as possible.

The efficiency of energy conversion of aerobic metabolism to external work is of great importance to sports exercise. Despite this fact, gross efficiency (GE) is not commonly used as a parameter in the assessment of cyclists’ exercise ability. It is also known that road cyclists traverse most of their route at a work intensity below the anaerobic threshold (AT). We tried to examine the relationship between the standard aerobic parameters used for defining the endurance of cyclists and GE, measured just below the anaerobic threshold. Fifty cyclists were subjected to a progressive test. Work done and the basic respiratory and circulatory parameters were measured. Gross efficiency was calculated at work intensity just below AT. We observed a very low correlation (R = –0.137) between GE (24.9 ±2.06) and maximal oxygen uptake (VO2max) – 63.8 ±6,27 ml × kg–1 × min–1. The strongest correlation (R = –0.258) was recorded between GE and the percentage of maximal oxygen consumption (58.9 ±7.0%) for the load prior to the occurrence of the anaerobic threshold. The weak, but existing correlation between GE and selected respiratory and circulatory parameters may suggest that GE provides unique and independent information about the examined athletes.

Background. The aim of the study was to determine the effect of aerobic power interval training with added dead space (DS) on selected variables of physical fitness in amateur triathletes. Material and methods. The sample comprised 9 male amateur triathletes. The participants were divided into two groups, the control (K=4) and the experimental (E=5) group. In both groups two aerobic power units on a cycle ergometer were added. The training unit consisted of 15’ of warm up and the main part including 3’aerobic power intervals performed at the level of 90% of the power developed during the progressive test (90%VO2max). Between the exercises there were 6’ active rest intervals with the intensity of exercise of 50%VO2max. 2–6 repetitions were performed. In the experimental group the training included added DS of 1000 cm3 volume. The progressive test on a cycle ergometer was performed before and after 8 weeks of training. Results. After 8 weeks of training the following parameter values increased in the experimental group: maximal power, VO2max, respiratory minute volume and post exercise lactate level, by 6.9%, 8.5%, 9.2% and 12.9% respectively. A decrease in heart rate (HR) was noted in all the participants during exercise performed with the intensity of 100W (by 5.3%) and 250W (by 2.9%). In the control group the direction of changes varied. Conclusions. The application of the device increasing added DS during high intensity aerobic power interval training is more beneficial during training units of a similar length and can be included in the training program for amateur triathletes.

Wstęp. Celem pracy było ustalenie wpływu treningu interwałowego mocy tlenowej z dodatkową objętością oddechowej przestrzeni martwej (DOOPM) na wybrane zmienne wydolności fizycznej triathlonistów amatorów. Materiał i metody. Do badań przystąpiło 9 mężczyzn, amatorsko trenujących triathlon. Badani zostali podzieleni na grupę kontrolną (K=4) oraz eksperymentalną (E=5). Obu grupom donowanego tygodniowego mikrocyklu triathlonowego zostały dodane dwie jednostki mocy tlenowej na cykloergometrze. Jednostka treningowa składała się z 15” rozgrzewki oraz części głównej, w której wykonywano 3” interwały mocy tlenowej, ze stałą intensywnością na poziomie 90% mocy uzyskanej w teście progresywnym (90%VO2max). Pomiędzy tymi wysiłkami następowało 6” aktywnej przerwy z intensywnością 50%VO2max. Wykonywano od 2-6 powtórzeń. Grupa eksperymentalna wykonywała treningi z dodatkową objętością oddechowej przestrzeni martwej o objętości 1000 cm3. Test progresywny na cykloergometrze wykonano przed i po 8-tygodniach treningu. Wyniki. Po 8-tygodniach treningu u wszystkich badanych z grupy eksperymentalnej zwiększyły się: moc maksymalna średnio o 6,9%, maksymalny pobór tlenu średnio o 8,5%, maksymalna wentylacja minutowa płuc o 9,2%, powysiłkowe stężenie mleczanu średnio o 12,9%. Obniżenie częstości skurczów serca u wszystkich trenujących z DOOPM wystąpiło podczas intensywności 100W (o 5,3%) oraz 250W (o 2,9%). W grupie kontrolnej kierunek zmian nie był jednorodny. Wnioski. Wykorzystanie urządzenia zwiększającego DOOPM w bardzo intensywnym treningu interwałowym mocy tlenowej przynosi większe korzyści, przy podobnym czasie trwania jednostki treningowej i może zostać włączone do programu treningowego triathlonistów amatorów.
