Study aim: To determine the aerobic capacity of handball players with hearing impairment as compared with the healthy ones.Material and methods: Two groups of subjects took part in this study: healthy national handball players (NHB; n = 15) aged 18 - 33 years and international handball players with hearing impairment (IHB; n = 13), winners of European Deaf-Mute Championships in 2008 (Belgrade, Serbia) and second place in Deaflympic games in 2009 (Taipei, Taiwan), aged 21 - 48 years. Cosmed T-170 treadmill (FSPE1 protocol) and a breath-by-breath gas analyser were used to determine the following indices of aerobic capacity: maximal heart rate (HRmax), ‡O2max, oxygen pulse, lung ventilation, tidal volume, maximum speed.Results: Players from the IHB group attained significantly (p<0.05 - 0.01) lower values of oxygen pulse and maximum speed (by 12%), heart rate 1 min post-exercise (by 6%), lung ventilation (by 11%) and tidal volume (by 14%) compared with NHB group. IHB players had also twice lower weekly training volume. On the other hand, no significant between-group difference was found fo the relative O2max.Conclusion: The lower results attained by handball players with impaired hearing compared with the healthy ones could be attributed to lower training volume per week. Thus, an increase in the training volume for the disabled players would be recommendable.

The purpose of this study was to assess the effects of three different warm-up condi-tions on a 5K cycling time trial (TT). Sixteen trained cyclists completed the study. At the first testing session, participants completed a maximal graded exercise test to assess maximal oxygen consumption (VO2max) and a familiarization of the TT. At three subse-quent visits, the participants completed the TT after no warm up, short warm-up of three minutes at 60% VO2max, or long warm-up of ten minutes at 60% VO2max. The warm-up was assigned in randomized order. VO2, heart rate (HR), lactate, power, and speed were assessed after the warm-up, 1K, and completion of the 5K TT. There was no dif-ference between type of warm-up for time, power, cadence, speed, VO2, HR, or lactate levels at the end of the TT. There was no significant difference between type of warm-up for time, VO2 or HR at the end of the 1K split. Warm-up length was not impactful on 5K TT performance or during the first km of the TT in trained cyclists. These results con-flict with previous evidence indicating that a warm-up in endurance events primarily improved VO2 kinetics at the onset of the exercise.
