    Opis:
    The aim of this investigation was to determine the effectiveness of rating of perceived exertion (RPE) scale to measure plyometric exercise intensity during low (L), moderate (M) and high (H) intensity. Fourteen physically active students (age; 21±1.1 y, height; 178.7±8.2 cm and body mass; 74.6±9.1 kg) volunteered to participate in this study and performed each intensity once separated with 24 h recovery. The H consisted of 1 set of 5 repetitions at 90% of the subject’s vertical jump height (VJH). The M consisted of 10 repetitions at 70% VJT, and the L consisted of 1 set of 15 repetitions at 50% VJH. RPE was measured following the completion each intensity using 0-10 Borg RPE scale. Data was analyzed using repeated measures ANOVA and the level of significant was set at p < 0.05. The results indicated increases in RPE following enhancing exercise intensity (p < 0.05). Performing fewer repetitions at a higher intensity was perceived to be more difficult than performing more repetitions at a lower intensity. The results of the current investigation revealed that the RPE method is effective in monitoring different plyometric exercise and training intensities and it can be recommend that strength and conditioning professionals and athletes use the RPE method based on the effectiveness tool for monitoring their plyometric exercise and training sessions at different intensities.

    Opis:
    Listening to music can be useful for athletic performance because of the similarities between the rhythm of the music and the movements of the human body. Given the ambiguity in the lead for better music, the goal of this study was to investigate the effect of fast, light and favorite music on physiological function and physical performance of the male athlete students. 25 healthy male athlete students with the age of 20.8 ±1.20 years, height of 180.5 ±7.02 cm and weight of 70.8 ±10.9 kg participated in this study voluntarily. The present study was a repeated based test (4 times without music, fast, light and favorite music in 4 consecutive weeks with a one week rest apart them to control the effects of fatigue during the test). Results showed that fast music caused a significant changes in anaerobic power, sprint, agility, muscular endurance, aerobic power, rating of perceived exertion (RPE) (p < 0.05). Also, favorite music caused significant changes in explosive power and agility (p < 0.05). But, light music just made significant effect on minimum power (p < 0.05). According to this study, it seems that listening to fast music before aerobic and anaerobic activities can be effective on maximum and submaximal functions.

    Opis:
    Introduction: The Borg Scale for perceived exertion is well established in science and sport to keep an appropriate level of workload or to rate physical strain. Although it is also often used at moderate and high altitude, it was never validated for hypoxic conditions. Since pulse rate and minute breathing volume at rest are increased at altitude it may be expected that the rating of the same workload is higher at altitude compared to sea level.Material and methods: 16 mountaineers were included in a prospective randomized design trial. Standardized workload (ergometry) and rating of the perceived exertion (RPE) were performed at sea level, at 3,000 m, and at 4,560 m. For validation of the scale Maloney-Rastogi-test and Bland-Altmann-Plots were used to compare the Borg ratings at each intensity level at the three altitudes; p < 0.05 was defined as significant.Results: In Bland-Altmann-Plots more than 95% of all Borg ratings were within the interval of 1.96 x standard deviation. There was no significant deviation of the ratings at moderate or high altitude. The correlation between RPE and workload or oxygen uptake was weak.Conclusion: The Borg Scale for perceived exertion gives valid results at moderate and high altitude – at least up to about 5,000 m. Therefore it may be used at altitude without any modification. The weak correlation of RPE and workload or oxygen uptake indicates that there should be other factors indicating strain to the body. What is really measured by Borg’s Scale should be investigated by a specific study.

    Opis:
    The study determined physiological and psychophysical responses to fire fighters’ typical activities. Selfreported assessment of the most demanding fire fighting/rescue tasks were collected with a questionnaire. Then 19 voluntary fire fighters performed 3 simulated fire fighting/rescue tasks in protective clothing. Heart rate (HR), blood pressure and energy expenditure were measured; the rating of perceived exertion (RPE) was assessed with the Borg scale. The questionnaires showed that carrying out victims, fire suppression and resuscitation were classified as heavy load; climbing stairs with a hose as moderate load. According to RPE the subjects considered their effort during ladder climbing fairly light and only somewhat harder during stair climbing and carrying out injured people. The study demonstrated that typical fire fighting/rescue tasks were associated with high energy expenditure and imposed considerable cardiovascular stress. The Borg scale appeared not suitable for assessing perceived exertion in fire fighters during simulated tasks.

    Opis:
    Purpose: The purpose of this study was to investigate the effect of whole body vibration in oxygen uptake during intense squatting exercise with an added weight and whole body vibration compared with the same exercise without vibration. Methods: Nine male subjects performed three trials of dynamic squatting with an additional load of 50% of their body weight during 3 min. One trial without vibration, one trial with the frequency of 40 Hz and amplitude of 2 mm and one trial with the frequency of 40 Hz and amplitude of 4 mm. Results: The results showed no difference between the three experimental trials in relative and absolute oxygen uptake. However, the metabolic power and energy expended in whole body vibration (2 mm) were significantly different from exercise without vibration. The data analysis also showed a significant difference in rating of perceived exertion with whole body vibration (4 mm) compared with the exercise without vibration. Results showed that the addition of vibration stimulus has an increase in the energy expenditure particularly with 40 Hz and 2 mm amplitude, suggesting that the high metabolic power during heavy resistance training could be increased by the addition of vibration stimulation. Conclusions: Involuntary contractions generated by the vibration can be used by coaches to increase the intensity of heavy resistance training or to increase the energy expended during the workouts if the goal is a decrease of body mass.

    Opis:
    Music motivates, relaxes and stimulates action and is one factor which enhances the pleasure that people feel from a given movement. Thus, from a psychophysical point of view, listening to music is an important aspect in sport and recreation. With this in mind, the aim of the study was to determine any changes in the participants’ psychophysical sphere which resulted from listening to music while swimming. The psychophysical sphere was expressed in relation to the Borg RPE scale (Rating of Perceived Exertion) as well as the Rejeski and Gauvin Exercise-Induced Feeling Inventory (EFI) scale of emotional states. Material and methods: The participants in the study were not professional swimmers (n = 10). The experiment consisted of two trials in which participants performed the Swimming Cooper test. During the first trial there was no music transmitted while in the second trial specifically selected music was played as the participants swam. Results: An ANOVA variance analysis (α = 0.05) showed statistically significant differences in the RPE scale (p = 0.04) and across all sensations on the EFI scale (p = 0.001, p = 0.001, p = 0.001, p = 0.001). Conclusions: Listening to music while swimming has a significant impact on the human psychophysical sphere and is expressed by a perceived exertion scale and the scale of emotional states. Respondents paid less attention to the discomfort of physical exertion associated with exercise while listening to music. The rating of their emotional states, including positive engagement, revitalization and tranquility considerably increased though the physical exhaustion measures were significantly lower.
    Muzyka motywuje, relaksuje, pobudza do działania. Sprawia, iż człowiek odczuwa większą przyjemność z ruchu. Zatem z punktu widzenia psychofizycznego słuchanie muzyki jest ważnym elementem w sporcie i rekreacji. Dlatego celem badań było określenie zmian w sferze psychofizycznej człowieka wynikających ze słuchania muzyki podczas pływania. Sfera psychofizyczna wyrażona była skalą postrzegania wysiłku Borg’a (RPE) oraz skalą stanów uczuciowych Gauvin’a i Rejeskie’go (EFI). Materiał i Metody: W badaniach wzięły udział nie uprawiające zawodowo pływania osoby (n=10). Eksperyment złożony był z dwóch prób, w których uczestnicy wykonywali pływacki test Coopera. W pierwszej próbie nie przekazywano muzyki podczas wykonywania testu. W drugiej próbie indywidualnie dobrana muzyka była przekazywana w trakcie płynięcia. Wyniki: Analiza wariacji ANOVA (α=0.05) wykazała istotnie statystycznie różnice w skali RPE (p=0.04) oraz we wszystkich odczuciach skali EFI (p = 0.001, p = 0.001, p = 0.01, p = 0.001). Wnioski: Słuchanie muzyki podczas pływania istotnie wpływa na sferę psychofizyczną człowieka, wyrażoną skalą odczuwania wysiłku oraz skalą stanów uczuciowych. Badani zwracali mniejszą uwagę na wykonywany wysiłek i towarzyszący temu dyskomfort. Ocena stanów uczuciowych, w tym pozytywnego zaangażowania, rewitalizacji i spokoju istotnie zwiększyła się, a wyczerpania fizycznego istotnie zmniejszyła.

    Opis:
    Many hikers, mountaineers and climbers use telescopic sticks because they may aid walking up/downhill and may also ease the strain on the spine and the lower extremity joints particularly the knees. The reductions during downhill walking with hiking poles are caused primarily by the forces applied to the hiking poles and by a change in posture to a more forward leaning position of the upper body.In order to have any benefits from telescopic sticks, they must be used with the correct technique: The sticks must be height-adjustable and have handles that are constructed in a way that the user’s hands, when pressing down, firm support is provided (or gained). It is of utmost importance to use the sticks as close as possible to the body’s line of fall. It has been shown that there is no significant difference in using one or two sticks when walking without a load, but when walking with a load, balance is significantly enhanced by using two hiking sticks rather than one. Previously a possible loss of the ability to maintain balance in rough or exposed terrain (e.g. small ridges) has been discussed (Berghold, F. personal communication). However, this could not be supported by studies. At high altitude or in cold environment the sticks should not be adjusted too long (the hands should be lower than the elbow when using the stick), because otherwise the circulation will be impaired and the user will get cold fingers in a very short time.

    Opis:
    Aim. The aim of this study was to measure aerobic demands of fire fighting activities including exercise in the heat. Methods. Twenty-two experienced firefighters performed the Trondheim test simulating fire fighting tasks including work in the heat. Maximal oxygen uptake (VO2 max), heart rate (HR) and ventilation were recorded continuously. Data were compared with results obtained during a treadmill test during which the participants were dressed as smoke divers. Results. The participants completed physical parts of the Trondheim test in ~12 min (range: 7.5–17.4). Time to complete the test was closely related to the participant’s VO2 max. HR of ~170 beats/min and pulmonary ventilation of ~100 L/min were higher than at lactate threshold (LT) during laboratory tests. VO2 averaged over the test’s physical part was 35 ± 7 ml/min/kg, which was at the same or below the level corresponding to the participants’ LT. Physically fit participants completed the test faster than less fit participants. Slower and physically less fit participants consumed more air and used more oxygen than faster and physically more fit participants. Conclusion. The Trondheim test is physically demanding; it distinguishes physically fit and less fit participants.

    Opis:
    The extent to which self-report activity measured by the International Physical Activity Questionnaire (IPAQ) can substitute performance-based functional capacity measured by the Six-Minute Walk Test (6MWT) remains inconclusive. This study assessed Physical Activity (PA) and Functional Exercise Capacity (FEC); and also determined the relationship between PA and FEC in apparently healthy young adults. A total of 342 (145 males and 197 females) undergraduates of Obafemi Awolowo University, Ile-Ile, Nigeria participated in the study. The IPAQ was used to assess PA, while FEC was assessed using the 6MWT, and expressed in terms of the Six-Minute Walk Distance (6MWD), Six-Minute Walk Work (6MWW), Maximum Oxygen Uptake (VO2max) and Metabolic Equivalent (METS). Anthropometric and cardiovascular parameters were measured following standardized procedures. Data was analyzed using descriptive and inferential statistics. The alpha level was set at 0.05. The mean age of the participants was 22.0±2.87 years. The mean IPAQ score of all participants was 1471.4±1086.93. The percentage for low, moderate and high PA was 19% (65), 41.2% (141) and 39.8% (136), respectively. The mean 6MWD, 6MWW, VO2max and METS were 639.47 ±66.6 m, 41805.0 ±8520.6 kg·m, 28.9 ±1.92 mlO2k-1min-1, 4.05 ±0.32 mL/kg, respectively. There were signifi cant positive correlations between PA and each of the 6MWD (r=0.268; p=0.001), 6MWW (r=0.219; p=0.001), VO2max (r=0.268; p=0.001), METS (r=0.268; p=0.001). Measures of exercise capacity were not signifi cantly correlated with the anthropometric variables (p>0.05). Self-report of physical activity in healthy young adults does not adequately substitute the results of the Six-Minute Walk Test. Mbada Ch.E., Osifeso T.A., Johnson O.E., Okonji A.M., Odeyemi E.A.

    Wstęp: Stopień, w jakim deklarowana aktywność fizyczna oceniania za pomocą Międzynarodowego Kwestionariusza Aktywności Fizycznej (IPAQ) może zastąpić opartą o wyniki wydolność funkcjonalną mierzoną testem 6-minutowego chodu (6MWT) pozostaje niejednoznaczny. W badaniu tym oceniano aktywność fizyczną (AF) i funkcjonalną wydolność wysiłkową (FEC); a także określono zależność pomiędzy PA i FEC u pozornie zdrowych, młodych dorosłych. Materiał i metody: Badaniem objęto 342 studentów (145 mężczyzn i 197 kobiet) z Obafemi Awolowo University, Ile-Ile, Nigeria. IPAQ został wykorzystany do oceny AF, podczas gdy FEC oceniano za pomocą 6MWT i wyrażono w sześciominutowym dystansie chodu (6MWD), pracy wykonanej podczas sześciominutowego chodu (6MWW), maksymalnym minutowym poborze tlenu (VO2max) i równoważniku metabolicznym (MET). Parametry antropometryczne i układu krążenia były mierzone zgodnie ze standardowymi procedurami. Dane analizowano przy użyciu wnioskowania statystycznego i opisowego. Poziom alfa został ustalony na poziomie 0,05. Wyniki: Średni wiek uczestników wyniósł 22,0 ±2,87 lat. Średni wynik IPAQ wszystkich uczestników to 1471,4 ±1086,93. Procent dla niskiego, średniego i wysokiego poziomu AF to odpowiednio 19% (65), 41,2% (141) i 39,8% (136). Średni 6MWD, 6MWW, VO2max i METS wyniosły odpowiednio 639.47 ±66,6 m, 41805.0±8520,6 kg·m, 28,9±1,92 mlO2k-1min-1, 4,05±0,32 ml/kg. Istnieją znaczące dodatnie korelacje pomiędzy PA i każdym z 6MWD (r=0,268, p=0,001), 6MWW (r=0,219, p=0,001), VO2max (r=0,268, p=0,001), METS (r=0,268; p=0,001). Miary wydolności wysiłkowej nie były istotnie skorelowane ze zmiennymi antropometrycznymi (p>0,05). Wnioski: Deklarowany poziom aktywności fizycznej u zdrowych młodych dorosłych nie jest adekwatny do wyników testu sześciominutowego marszu.
