purpose of this study was to quantify the physiological requirements of various boxing exercises such as sparring, pad work, and punching bag. Because it was not possible to measure the oxygen uptake (VO2) of ‘‘true’’ sparring with a collecting gas valve in the face, we developed and validated a method to measure VO2 of ‘‘true’’ sparring based on ‘‘postexercise’’ measurements. Nine experienced male amateur boxers (Mean 6 SD: age = 22.0 ± 3.5 years, height = 176.0 ± 8.0 cm, weight = 71.4 ± 10.9 kg, number of fights = 13.0 ± 9.5) of regional and provincial level volunteered to participate in 3 testing sessions: (a) maximal treadmill test in the LAB, (b) standardized boxing training in the GYM, and (c) standardized boxing exercises in the LAB. Measures of VO2, heart rate (HR), blood lactate concentration [LA], rated perceived exertion level, and punching frequencies were collected. VO2 values of 43.4 ± 5.9, 41.1 ± 5.1, 24.7 ±
6.1, 30.4 ± 5.8, and 38.3 ± 6.5 ml.kg1.min1 were obtained, which represent 69.7 ± 8.0, 66.1 ± 8.0, 39.8 ± 10.4, 48.8 ± 8.5, and 61.7 ± 10.3%VO2peak for sparring, pad work, and punching bag at 60, 120, and 180 b.min1, respectively. Except for lower VO2 values for punching the bag at 60 and 120 b.min1 (p < 0.05), there was no VO2 difference between exercises. Similar pattern was obtained for %HRmax with respective values of 85.5 ± 5.9, 83.6 ± 6.3, 67.5 ± 3.5, 74.8 ± 5.9, and 83.0 ± 6.0. Finally, sparring %HRmax and [LA] were slightly higher in the GYM (91.7 ± 4.3 and 9.4 ± 2.2 mmol.L1) vs. LAB (85.5 ± 5.9
and 6.1 ± 2.3 mmol.L1). Thus, in this study simulated LAB sparring and pad work required similar VO2 (43–41 ml.kg1.min1, respectively), which corresponds to;70%VO2peak. These results underline the importance of a minimum of aerobic fitness for boxers and draw some guidelines for the intensity of training.

GENERAL PRESENTATION

The 2011 edition of the Scientific Congress on Martial Arts and Combat Sports (SCMACS) will take place on 13h 14th and 15th May 2011 in Viseu (Portugal). The organizing committee of this event fully believes that this initiative will provide a valuable opportunity to promote, enlarge and strengthen the scientific community gathered around martial arts and combat sports.

The central issue of this Congress is the scientific interpretation of actions in broader contexts as Martial Arts (MA), Combat Sports (CS) or Self-Defence (SD), in relation to objectives usually associated with human development (health, education and well-being).

Participation in this congress should be as wide as possible. Instructors education and training, aiming at the development of skills throughout Polytechnic and University higher education study cycles, is a clearly medium-/long-term fundamental objective on the world, with a growing presence in the markets of physical activity (health, well-being and fitness), sports (from education to sport practice) and school physical education (given the eclectic, inclusive and multilateral context of this school subject). This trajectory, however, should be followed in connection with research developed and practice in scientific centres.

We firmly believe researchers, as well as undergraduate and post-graduate students (covering the levels of bachelor’s, master’s and Ph.D.), in the field of martial arts and combat sports, will be ready to present their research and share the richness of their experiences. This will surely contribute to strengthening this scientific community, which is growing and acquiring importance as a forum for the social development of Sports and Education at the European level and even worldwide, given its multicultural nature (East/West), usually more explored in non-scientific contexts.

In this way, we challenge all cultural and scientific organisations, particularly higher education and research institutions developing scientific activities related to the field in question, as well as federations with public usefulness purposes in the scope of martial arts and combat sports, to disseminate this information among potentially interested researchers, educators and practitioners, stimulating them to participate in this event as speakers and poster presenters. All committed communities of technicians and advanced practitioners of martial arts and combat sports will certainly be interested in participating in this congress and they can expect full support from us to do it.

The Congress is a non-profit event and no speaker fees will be paid by the organising committee. However, efforts will be carried out to cover foreign guest speakers’ logistic expenses (through registration fees funding). Any eventual profit will be invested in the publication of the congress proceedings.

The financial management of this first edition may count on the professional support provided by ADIV (Viseu’s Association for Development and Research), which is integrated in the Polytechnic Institute of Viseu, the higher education institution assuming the coordination of this congress, specifically through its School of Education .
