PURPOSE The purpose of this study was to identify a sport-specific assessment for elite race walking athletes by comparing physiological responses to different types of walking graded exercise test (GTX) protocols. METHODS Six elite race walking athletes completed two types of walking protocols in a randomized crossover design with 1 week of interval between trials. Exercise time, oxygen uptake (VO2), ventilation (VE), and heart rate (HR) were measured in each trial; the lactate level was measured during the recovery period. RESULTS VO2, VE, and HR differed significantly between the trials (p<.01~.05). Exercise time (p<.01) and VO2 (p<.05) differed significantly between the walking protocols; however, VE and HR did not differ significantly. During the recovery period, lactate levels differed significantly between the trials (p<.01), but not the walking protocol. CONCLUSIONS These results suggest that modified walking GXT protocols were appropriate to assess elite race walking athletes.
Purpose The purpose of this study was to examine the relationship between the track records and physical abilities in elite cyclists(keirin). Methods Twenty three elite cyclists were measured height, weight, lower body circumference(thigh, calf, and ankle), basal physical abilities(grip/back muscle strength, 25m sprint, Sargent jump test, Burpee test, shuttle run test), one-repetition maximum(1RM) strength(back squat, bench press, leg curl, power clean, dead-lift, leg press), aerobic capacity(V̇O2max, METs, HRmax), and track records(200m and 500m). Stepwise multiple regression analyses were performed to investigate which physical abilities related to track records. Results A statistically significant relationship was found between 200m track records and 2 variables which were the thigh circumference and 1RM leg press(p<.05). Also, the thigh circumference and 1RM leg press were significantly related to 500m track records(p<.05). Conclusions The results showed that the thigh circumference and maximal strength were associated with the track records in elite cyclists(keirin).
Purpose The purpose of this study was to examine the relationship between performance factors and physical fitness in secondary school female biathlon athletes. Participants in this study were 14 female biathlon athletes. Methods All factors such as aerobic capacity(VO2max, %AT), wingate test(peak power, average power, fatigue index), isokinetic test(trunk, knee, hip, ankle), 1RM test(leg press, chest press, lat pull down), physical fitness(grip, knee and back muscle strength, sit & reach, power, agility) were tested. In order to analyze collected data, pearson product moment and multiple regression analysis were utilized. The results were summarized as follows : First, there was a significant correlation between aerobic. Results The results were summarized as follows : First, there was a significant correlation between aerobic capacity and three factors(standing broad jump, isokinetic test 60° right knee extension)(p<.01). There was a significant correlation between wingate test and four factors(isokinetic test 30° left ankle ever, 30° right ankle ever, 120° left ankle inver, leg press)(p<.10). Conclusion These results suggested new evidence that ankle strength is necessary for performance in female biathlon athletes.
