“…where F = drag force, m = mass riding on the roller skis, and g = acceleration of gravity. A technique for determining the pk of roller skates has been described by de Boer, Vos, Hutter, de Groot, and van Ingen Schenau (1987). With this technique, F was measured while towing a weighted sledge (roller skates mounted under a board) or a subject wearing the skates.…”

A theoretical analysis was used to evaluate the effect of body mass on the mechanical power cost of cross-country skiing and roller skiing on flat terrain. The relationships between body mass and the power cost of overcoming friction were found to be different between cross-country skiing on snow and roller skiing. Nevertheless, it was predicted that the heavier skier should have a lower oxygen cost per unit of body mass for roller skiing, as is the case for snow skiing. To determine whether the theoretical analysis was supported by experimental data, oxygen consumption measurements were performed during roller skiing by six male cross-country ski racers who spanned a 17.3-kg range in body mass. The theoretical analysis was supported by the experimental findings of decreases in oxygen consumption for each kg increase in body mass of approximately 1.0% for the double pole technique, 1.8% for the kick double pole technique, and 0.6% for the VI skate technique.

“…50.4) and low walking are two skating 647 activities which can be performed anywhere, but low walking is usually performed going up a hill ( Fig. Because maximal speed between speed skating and in-line skating is different, heart rate may be a better indicator of exercise intensity than speed (de Boer et al 1987c). Physiologically and biomechanically, a skater responds differently to low walking and dry skating, therefore activities more similar to speed skating such as slide board exercise (Fig.…”

“…Comparable with speed skating on ice, it is characterized by a deep-seated body position causing a high static load on propulsive muscles. Therefore, intramuscular pressure within the main propulsive muscle groups (knee and hip extensors) is high, resulting in restricted blood flow during major parts of the stroke cycle (5,9,13,17). This may impede the transport of lactic acid from working muscles in particular at higher intensities, resulting in lower blood lactate concentrations toward the end of a graded test (as compared with intramuscular values) and higher concentrations after cessation of exercise.…”

Validity of Lactate Thresholds in Inline Speed Skating

Lactate thresholds are commonly used as estimates of the highest workload where lactate production and elimination are in equilibrium (maximum lactate steady state [MLSS]). However, because of the high static load on propulsive muscles, lactate kinetics in inline speed skating may differ significantly from other endurance exercise modes. Therefore, the discipline-specific validity of lactate thresholds has to be verified. Sixteen competitive inline-speed skaters (age: 30 ± 10 years; training per week: 10 ± 4 hours) completed an exhaustive stepwise incremental exercise test (start 24 km·h, step duration 3 minutes, increment 2 km·h) to determine individual anaerobic threshold (IAT) and the workload corresponding to a blood lactate concentration of 4 mmol·L (LT4) and 2-5 continuous load tests of (up to) 30 minutes to determine MLSS. The IAT and LT4 correlated significantly with MLSS, and the mean differences were almost negligible (MLSS 29.5 ± 2.5 km·h; IAT 29.2 ± 2.0 km·h; LT4 29.6 ± 2.3 km·h; p > 0.1 for all differences). However, the variability of differences was considerable resulting in 95% limits of agreement in the upper range of values known from other endurance disciplines (2.6 km·h [8.8%] for IAT and 3.1 km·h [10.3%] for LT4). Consequently, IAT and LT4 may be considered as valid estimates of the MLSS in inline speed skating, but verification by means of a constant load test should be considered in cases of doubt or when optimal accuracy is needed (e.g., in elite athletes or scientific studies).
