- The aims of the study were (1) to investigate the effects of participation in low impact body conditioning classes on physical fitness in sedentary women at different ages and (2) to examine the correspondence between physical self-concept and participation in, and fitness change after, the participation. Ninety-two sedentary women (mean age 44.2 years) participated in 11-weeks of bi-weekly classes that included cardiovascular, strength, core, endurance and mobility exercises, all performed in synchrony with music. Cardiorespiratory fitness, maximal lifting strength, mobility and balance tests were performed pre- and post the exercise period and the short-form Physical Self-Description Questionnaire (PSDQ-S) was completed. Zero-order Spearman correlation analyses showed that women who rated the PSDQ-S dimension Sport competence higher participated in a larger number of sessions (rs=0.24, p=0.040). At post-tests, all participants had increased their balance, the participants aged 20-34 years had increased their lifting strength, and the participants aged 35-65 years had increased their cardiorespiratory fitness and mobility. Most PSDQ-S dimensions did not affect performance change, but the perception of being physically active was related to increased cardiovascular fitness. We conclude that women with a sedentary lifestyle who wish to increase their physical capacity benefit from music exercise and that inquiries about perceived sport competence and physical activity can improve recommendations made by strength and conditioning professionals.

- One of the major parameters in music is the overall speed of a musical performance. In this study, a computational model of speed in music audio has been developed using a custom set of rhythmic features. Speed is often associ-ated with tempo, but as shown in this study, factors such as note density (onsets per second) and spectral flux are important as well. The original audio was first separated into a harmonic part and a percussive part and the fea-tures were extracted separately from the different layers. In previous studies, listeners had rated the speed of 136 songs, and the ratings were used in a regression to evalu-ate the validity of the model as well as to find appropriate features. The final models, consisting of 5 or 8 features, were able to explain about 90% of the variation in the training set, with little or no degradation for the test set.

- OBJECTIVES: To assess the physical and psychological effects across 11 weeks of music-exercise sessions, the participants' training experience, and attitudes towards physical activity. The effect of different music information was also investigated.METHODS: Overall, 146 sedentary volunteers were randomized into 4 exercise groups and each group received different music information. Physical capacity and psychological measures were obtained.RESULTS: Increased performance in oxygen uptake and flexibility and decreased blood pressure was found. Participants reported increased wellbeing and body-awareness, and an intention to remain physically active. No differences between groups were found.CONCLUSION: Music-exercise can be recommended to promote physical activity among sedentary individuals. The amount of musical information in synchronous music seems not to have any effects on self-selected intensity or physiological benefits.

- There is an apparent contradiction between the narrow range of tempi optimal for perceptualjudgment and motor synchronization and the wide range of beat tempi found in real music. Therelation between listeners’ perception of speed and beat tempo was therefore investigated, both forreal music excerpts (ME) and metronome sequences. Tempi ranged from 42 to 200 beats per minute (BPM), and some excerpts were further tempo manipulated in four levels from from ±5 to ±20%. Regression analyses showed that speed was a shallower function of original tempo for fast (> 150 BPM) and slow (< 95 BPM) MEs than for MEs with intermediate tempi, describing anon-linear, sigmoid function. Manipulated tempo had twice as large an effect on speed as hadoriginal tempo. In contrast, speed was an almost linear function of tempo for metronome sequences.Taken together, these results show that the non-linearity stems from properties of the musical signal,rather than being a subjective perceptual effect. They indicate an inverse relation between tempo andrelative event density in real music, and demonstrate that the perception of periodic signals isaffected not only by the beat level, but also by faster and slower levels.© 2010 Acoustical Society of America.

- Given that physical performance is enhanced by listening to music, what information in the music is the active ingredient? Here, we varied the amount of music information in an otherwise identical piece of music, from only the rhythm, through a synthesized and scaled down version, to the full original version. Twenty-two university students (11 males and 11 females) ran for 10 minutes to each of eight conditions, two with white noise, three with music that facilitated synchronization with the running pace, and three with tempi where synchronization was impossible. Dependent variables were distance run and the number of steps, from which stride length was computed. Heart rate and mood (PANAS) were also measured for control purposes. Participants tended to run a greater distance when there was more music information, which was mainly an effect of longer strides rather than a faster stride rate. This effect was stronger in the synchronous conditions. The results suggest that the motivational effects of music information during running is mostly related to richer temporal information conveyed by faster metrical levels, when attempting to synchronize with the beat in the music
