The purpose of this study was to investigate the impact of fast- and slow-tempo music on 500-m rowing sprint performances. Twenty-two rowers performed 500-m sprints 3 times: rowing without music, rowing to slow music, and rowing to fast tempo music. Strokes per minute (SPM), time to completion, (TTC), and rated perceived exertion (RPE) were recorded. Although RPE did not differ between the rowing conditions, TTC was shortest in the fast music condition. Further, shorter TTC was observed in the slow music condition in contrast to the control condition, indicating that slow music also enhanced performance. The strongest treatment effects emerged, however, in the examination of the SPM that were significantly higher during rowing to fast music in comparison with rowing to slow music or no music. These results suggest that fast music acts as an external psyching-up stimulus in brief and strenuous muscle work.

Eighty volunteers were tested in their natural exercise environment consisting of a fitness centre they regularly attended. Half of the sample exercised on a stationary bicycle, the other half on a treadmill. All participants filled in the Exercise-Induced Feeling Inventory before and after their 20 min of exercise that was performed at self-selected workload. The results revealed that exercise intensity and the other parallel measures like heart rate, perceived exercise intensity and estimates of burned calories were higher in participants who ran in contrast to those who cycled. There were no differences in self-reports of enjoyment of the exercise sessions and in the psychological improvements from pre- to post-exercise between the groups. It is concluded that significant psychological improvements occur even after a 20-min bout of exercise and these changes are independent of the workload or exercise intensity.

The scholastic literature contains hundreds of references on subjects of exercise and Internet addiction. These two opposite addictions, in terms of physical-energy requirements and physical versus cognitive components, are examined. Commonalities and differences are explored in parallel. While both forms of addictions share common symptoms that meet the theoretically proposed characteristics of behavioural addiction, they are different in several ways: Exercise addiction is specific to a form or a collection of forms of physical activity(ies), but Internet addiction is unspecific (the activity could be sex, gambling, e-mail, shopping, video games and other). Exercise is an activity while the Internet is a medium on which different activities take place. The existence of these two addictive behaviours is also questioned while exploring co-morbidities accompanying these two problematic behaviours. It is suggested that both addictions may be manifestation of other behavioural problems rather then being a diagnosable psychiatric illness on their own. It is not surprising, then, that the DSM IV does not contain a classification for these problematic behaviours.

Szakirodalmi áttekintésünk egy olyan pszichológiai rendellenességet tárgyal, amelyben a kompulzív és obszesszív jellegű, túlzott mennyiségű testedzés valamilyen stressz vagy más pszichológiai probléma tüneteként jelentkezik. Ezt a ritka, de súlyos diszfunkciót testedzésfüggőségnek nevezzük. Ennek a deviáns edzési magatartásnak az okát a behaviorista elmélet a pozitív és negatív megerősítés alapján próbálja magyarázni, határvonalat húzva az egészséges és a beteges sportolás, illetve testedzés között. Az elemzés során egy fiziológiai és egy pszichológiai modellt mutatunk be. Áttekintjük a viselkedési függőségekben megjelenő alapvetőnek tekinthető közös tüneteket, a rendellenesség definiálásához alkalmazott vizsgálati módszerünk ezt a célt szolgálta. Egyúttal fel kell hívnunk a figyelmet arra is, hogy a testedzésfüggőség esetében az elterjedt kérdőíves módszer korlátokkal bír, a pontos diagnózis érdekében a jelenség mögött álló pszichológiai indítékot az erre képzett szakembereknek kell tovább vizsgálni.

The aim of this study was to determine the effect of exercising up and down stairs on physical fitness of Baitul Jannah Islamic Boarding School students by measuring cardiovascular endurance using the Rockport test. This study uses a preexperimental research method with pretest-posttest technique, by giving up and down stairs exercise for eight weeks. The sample of this study were 20 male students aged 20-23 years old and had been staying in the boarding schools for at least 3 years. The results of the study revealed that there were significant differences between before and after being given the exercise. Thus there is an effect of exercising up and down stairs on increasing physical fitness.
