Comparação da composição corporal, desempenho aeróbio e anaeróbio entre ciclistas e triatletas competitivos

Abstract

Comparison of body composition and aerobic and anaerobic performance between competitive cyclists and triathletes Comparação da composição corporal, desempenho aeróbio e anaeróbio entre ciclistas e triatletas competitivosAbstract -The aim of this study was to compare anthropometric characteristics and aerobic and anaerobic fitness between competitive cyclists and triathletes. The sample consisted of 11 cyclists and 12 triathletes with experience in competitions. The tests were performed on two different days, with an interval of 48 h between sessions. On the first day, the athletes were submitted to anthropometric assessment (body mass, height, and skinfold thickness) and a maximal incremental test to determine maximal oxygen uptake, maximum power, maximum heart rate, maximum lactate, and the first (LL 1 ) and second lactate threshold (LL 2 ). The Wingate test was conducted on the second day to determine peak power, average power, and fatigue index. There were significant difference (p < 0.05), with medium effect size (0.80 -1.5), in mid-thigh skinfold thickness (15.2 ± 6.3 and 10.5 ± 4.8 mm), power at LL 1 (195.0 ± 30.9 and 162.7 ± 28.3 W), power at LL 2 (247.6 ± 25.0 and 219.7 ± 37.9 W), and fatigue index (47.2 ± 13.0 and 60.1 ± 16.4%) between cyclists and triathletes, respectively. The other variables did not differ between groups. Anthropometric characteristics are similar in triathletes and cyclists. However, cyclists present higher power outputs at the lactate thresholds (LL 1 and LL 2 ) and lower fatigue indexes.

Can power and anaerobic capacity reduce according to disordered eating behaviors in cyclists?

“…Verbal encouragement was given throughout the test. Cyclists were asked to maintain a cadence of pedaling of 120 rpm to begin the Wingate test, aiming to reduce the cycle ergometer's inertia, following the methodology used in the study performed by Moro et al 18 . External power was calculated every one second.…”

“…From a practical point of view, PP is a good indicator of an athlete's capacity to sprint for a short time, frequently used at certain moments of a road cycling race, especially the last 50 meters 4 . It seems that the capacity for short-distance sprinting can decide whether someone will win or lose in certain cycling events 18 . According to the results of the present study, the adoption of DEBs appears not to affect the capacity for short-distance sprinting among cyclists.…”
