Medicine and Science in Sports and Exercise 43 Each zone contains 42 loops and two temperature sensors that sit within underground boxes connected to one another with plastic conduit. Insgesamt befinden sich 3 Bilder in dieser Galerie. As shown in our study and by others Bogdanis et al. As blood lactate production can be inhibited to some extent, oxidative metabolism is favored which might be beneficial in some specific energieberejtstellung sessions aiming to improve aerobic power.

The maximal m all-out ergometer performance tests MPT were performed on a wind-resistance-braked rowing ergometer Concept 2, Morrisville, VT, USAwith the resistant level set from 4 to 6. Warming-up prior to a competitive exercise bout is a widely accepted practice in sports, with athletes and coaches alike believing that warming-up is essential for attaining optimal performance McGowan et al. Riviera Water Park Riviera is one of the biggest water parks in Europe and the biggest one in Russia with a total area of 20, square meters was opened in Kazan, September, Research interests Training monitoring, exercise testing, E-mail: Although muscle metabolites have not been measured in detail, for rowing exercise, there is evidence that the relatively long duration exercise at an intensity close to maximal oxygen uptake will decrease phosphocreatine stores and increase muscle lactate levels substantially Mavrommataki et al.

Website Toyota Park, Chicago. Toyota Park, Chicago Toyota Park, the fourth major soccer-specific field in the United States, features a state-of-the-art Uponor turf-conditioning system that keeps the playing surface in excellent condition year-round, no matter the weather or temperature.

Future studies should focus on different HIE pre-load conditions such as performing only leg energiebereifstellung, lower La induction, or different pacing strategies.

On sunny days, the demand for warmth varies from zone to zone, depending on the position of the sun. Interestingly, the rowers were able to perform the second m of the MPT with same split times indicating a limit at the start but not for the rest of the workout, which was performed at the sporrt RPE. Body composition was measured using dual-energy X-ray absorptiometry. Additional studies are needed before any conclusions can be drawn.

VO 2max – energiebereitstellungg oxygen consumption; VE- maximal ventilation; VT 1 – first ventilatory threshold; VT 2 – second ventilatory threshold; P max – maximal aerobic power ; HR max — maximal heart rate. An active warm-up is a routine performed by most athletes to improve competitive performance. The sensors in each zone communicate an average demand back to a series of control valves, which modulate the flow of warm water in response.

These authors concluded that prior heavy exercise increased the primary VO 2 amplitude and increased the tolerable duration of severe exercise performed after 10 min of recovery. According to Roth et al. VO 2 per W economy was higher in the HIE preload situation indicating a shift from anaerobic to a slightly higher aerobic energy contribution Figure 2.

Medicine and Science in Sports and Exercise 32 Different warm-up protocols for the m maximal performance test MPT. This increase in split times was only significant for the first m, which might be attributed to racing strategy influenced by the pre-load situation. Currently, pacing is more or less the same in all rowers, starting fast and trying to sustain the high La concentration induced by the start for the rest of the race.


Maksimir stadium, Zagreb After the renovation, the field at Maksimir stadium in Zagreb, Croatia is now equipped with Uponor Meltaway, a snow and ice melting system. Abstract Elevated blood lactate has been shown to influence subsequent anaerobic exercise due to an inhibition of glycolysis.

We suggest that the reduced net La production with a higher oxygen uptake per W may allow a faster or longer start sprint. Alternatively, athletes use one specific warm-up protocol, which has successfully been applied previously by other athletes or during their own practice McGowan et al.

Research interests Exercise physiology, body composition, pediatric endocrinology E-mail: Calculations of turn points were performed by a computer-aided linear regression break point analysis Hofmann et al. International Journal of Sports Physiology and Performance 7 Rowers performing the HIE pre-load had higher La values at the beginning of the MPT, which significantly diminished the increase in net La concentration and lactic anaerobic energy contribution. Sport facilities are designed as a gift to Sigulda residents and guests of the city.

Nine well-trained college level male rowers Energiebereitstlelung Physiology 94 In that study it was shown that heavy-intensity priming exercise increased aerobic contribution early in exercise, reduced the amplitude and trajectory of the VO 2 slow component and increased VO 2peakproviding a greater scope for the VO 2 response Burnley et al.

This was associated with a significant increase in power. As we increased La with the arms in the HIE pre-load, fatigue might remain evident until the start of the MPT indicating that the time to the start may be also an important factor which should be investigated systematically. Blood Lactate concentration mmol. All data were processed by means of computer-supported analysis applying standard software MetaSoft 3 Version: Accordingly, the increased La concentration as a result of HIE pre-load had small but negative consequences for overall performance in the MPT in our study.

The first m of the MPT high Figure 2 were slower but not the second m whereas the m split times of the first m were 0. Medicina Dello Sport 53 Net La increase from rest to the end of the MPT low was
