Introduction Patients with implantable cardioverter defibrillator require physical therapy due to their decreased physical fitness. This is why standardized training has been designed for groups of subjects of varying endurance. Material and methods Patients with heart failure and implantable cardioverter defibrillator who wished to do interval training program. The program included 55 patients. We divided them into two study groups. The first group had lower exercise tolerance level (3.94 ± 0.72 MET), and the other had higher exercise tolerance level (7.97 ± 1.80 MET). The training group had an 8-week long training program. The patients received treatment at an outpatient clinic three times a week. Patients had cardiac stress tests with modified Bruce protocol before receiving physical therapy and after they have finished the training program. We assessed the metabolic equivalent of task (METS), the duration of exercise, blood pressure, heart rate and BMI. Results We observed longer duration of cardiac stress test performance and improvement of exercise tolerance. In patients from the group with lower exercise tolerance, the level of exercise tolerance was 3.94 ± 0.72 MET before therapy and rose to 5.93 ± 1.12 MET (p < 0.001) after therapy. In the group of higher exercise tolerance, the level was 7.97 ± 1.80 MET before therapy and rose to 9.32 ± 2.01 MET (p < 0.001) after the training cycle. Conclusions Participation in 8-week interval training cycle resulted in greater increase of exercise tolerance and exercise time, as well as hemodynamic parameters in patients with lower exercise tolerance.

The aim of the study was to compare the effect of an increasing-distance interval-training program and a decreasing-distance interval-training program, matched for total distance, on aerobic and anaerobic performance capabilities. Forty physical education students were randomly assigned to either increasing- or decreasing-distance interval-training group (ITG and DTG), and completed two similar sets of tests before and after six weeks of training. One training program consisted of 100 – 200 – 300 – 400 – 500m running intervals, and the other 500 – 400 – 300 – 200 - 100m. While both training programs led to a significant improvement in 2000m run (ES = 0.02-0.68), the improvement in the DTG was significantly greater than in the ITG (18.3 ± 3.6 vs. 12.2 ± 3.2 %, p< 0.05). In addition, while both training programs led to a significant improvement in 300m run (ES = 0.25-0.73), the improvement in the DTG was significantly greater than in the ITG (21.1 ± 1.8 vs. 15.4 ± 1.1 %, p< 0.05). The findings indicate that beyond the significant positive effects of both training programs, the DTG showed significant superiority over the ITG in improving aerobic and anaerobic performance capabilities. Athletes should acknowledge that, in spite of identical total work, interval-training program might induce different physiological impacts if order of intervals is different.

The efficacy of replacing generic running with Taekwondo (TKD) specific technical skills during interval training at an intensity corresponding to 90-95% of maximum heart rate (HRmax) has not yet been demonstrated. Therefore, the purpose of this study was to compare the HR responses and perceived exertion between controlled running and high-intensity TKD technical interval training in adolescent TKD athletes. Eighteen adolescent, male TKD athletes performed short-duration interval running and TKD specific technical skills (i.e. 10-20 [10-s of exercise interspersed with 20 s of passive recovery]) in a counterbalanced design. In both training methods, HR was measured and expressed as the percentage of HR reserve (%HRres). Rating of perceived exertion (RPE, Borg's category rating-10 scale), Banister's training impulse (TRIMP) and Edwards' training load (TL) were used to quantify the internal training load. Recorded cardiovascular responses expressed in %HRres in the two training methods were not significantly different (p > 0.05). Furthermore, the two training methods induced similar training loads as calculated by Banister and Edwards' methods. Perceived exertion ranged between "hard" and "very hard" during all interval training sessions. These findings showed that performing repeated TKD specific skills increased HR to the same level, and were perceived as producing the same training intensity as did short-duration interval running in adolescent TKD athletes. Therefore, using specific TKD kicking exercises in high-intensity interval training can be applied to bring more variety during training, mixing physical and technical aspects of the sport, while reaching the same intensity as interval running.

Background: The purpose of this study was to determine changes in anaerobic capacity at 100% physical effort intensity in the examined people.Material/Methods: 12 male students from the University of Physical Education in Warsaw were subject to these examinations. The average age was 23.6 years, mean body height 178.7 cm, and body mass 80.6 kg. The experiment was carried out from 7th January to 8th March 2008. The experiment (one group) was carried out in two stages. The first stage had 25 training units on a cycloergometer within 5 weeks. The second stage was connected with controlling the obtained results for 3 consecutive weeks after completing the training. An individual load consisted of 6 efforts (10s work, 60s rest) performed with intensity at 100% of the individual's maximum power in consecutive test trials. All training and test trials were performed by means of the Monark 824E (Sweden) cycloergometer linked with a PC computer, MCE v.4.0 software.Results: The results revealed that effort stimuli made significant changes in mechanical work, maximum power, time of achieving maximum power after a four-week period of exercises on a cycloergometer.Conclusions: The used training loads significantly affected the improvement of the results in terms of mechanical work, maximum power, time of developing and maintaining it.The dynamics of changes of anaerobic capacity parameters, after completing the training, may be used as a factor of reliable steering the training loads in terms of intensity.

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.

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.
