“…Similar results have also been reported for the relationship of %FT to peak torque decline on an anaerobic isokinetic fatigue test (10,29). In agreement with previous studies using cycle ergometer (20) and isokinetic (11) tests, negative correlations were found between V02 max and power decrease during the WT. Also significant differences occurred in PD values for both the upper and lower Lower Body Wingate Test body between the biathletes and control subjects.…”

This study compared power outputs (PO) from both the upper body (UB) and lower body (LB) Wingate tests of anaerobic power between biathletes and control subjects. Ten biathletes (B) selected by the British Ski Federation for potential assignment to the British team and 13 control (C) subjects cranked or pedaled the same Bodyguard ergometer at maximal RPMs for 30 s against resistances of 2.94 and 4.41 J/rev/kg body weight (BW), respectively. POs were calculated in watts (W) and expressed as peak power (PP, highest 5-s interval), mean power (MP, the mean for 30 s), and power decrease (PD, difference between PP and lowest 5-s PO divided by time). Absolute PP and MP for both UB and LB did not differ between groups. A comparison of POs made relative to BW showed B to have higher values than C: 11.25 vs 10.25 W/kg for LB PP (P less than .05) and 9.21 vs 7.96 W/kg for LB MP (P less than .001). The data expressed relative to kg fat free mass (FFM) showed only MP to be significantly greater in B compared with C (P less than .001). Similar PO relationships were found for the UB where PP (P less than .01) and MP (P less than .001) expressed per kg BW and MP (P less than .001) expressed per kg FFM were higher for B than C. Concomitantly, PD was lower in B than C for both the UB (P less than .05) and LB (P less than .01).(ABSTRACT TRUNCATED AT 250 WORDS)

“…1 and 4) became progressively higher the longer the distance specialty, indicating a greater reliance on aerobic energy yield in the longer running events, The corresponding properties of the marathon runners did not follow this trend, however, suggesting that other qualities are of importance in this event. One such factor may be the capacity to oxidize free fatty acids in skeletal muscle (5,11).…”

Physiological characteristics of elite runners from different racing events were studied. Twenty-seven middle- and long-distance runners and two 400-m runners belonging to the Swedish national team in track and field were divided, according to their distance preferences, into six groups from 400 m up to the marathon. The maximal oxygen uptake (VO2 max, ml X kg-1 X min-1) on the treadmill was higher the longer the main distance except for the marathon runners (e.g., 800-1500-m group, 72.1; 5000-10,000-m group, 78.7 ml X kg-1 X min-1). Running economy evaluated from oxygen uptake measurements at 15 km/h (VO2 15) and 20 km/h (VO2 20) did not differ significantly between the groups even though VO2 15 tended to be lower in the long-distance runners. The running velocity corresponding to a blood lactate concentration of 4 mmol/l (vHla 4.0) differed markedly between the groups with the highest value (5.61 m/s) in the 5000-10,000-m group. The oxygen uptake (VO2) at vHla 4.0 in percentage of VO2 max did not differ significantly between the groups. The blood lactate concentration after exhaustion (VO2 max test) was lower in the long-distance runners. In summary, the present study demonstrates differences in physiological characteristics of elite runners specializing in different racing events. The two single (but certainly inter-related) variables in which this was most clearly seen were the maximal oxygen uptake (ml X kg-1 X min-1) and the running velocity corresponding to a blood lactate concentration of 4 mmol/l.

In brief: Two ultramarathon world-record holders were studied immediately after a 50-mile race and in a laboratory under controlled conditions. Blood samples were obtained before and after running and were analyzed for lactate, glucose, glycerol, and free fatty acid. Muscle biopsies were also performed and analyzed for glycogen, enzyme activity, and fiber type. Results showed that although these runners are fit their physiological data are not extreme or unique and are similar to data obtained from marathoners.
