摘要：Swimming requires high muscle strength and technical ability in order to achieve a good performance. In the swimming,performance depends on a number of factors including development of relevant muscle groups and anthropometry. There is a strong correlation between age and height variables and swimming performance (8). On the other hand,Mameletzi et al. (6) reported that there is a relationship between lean body mass (LBM) and knee muscles strength. Although in freestyle,stroke speed is little influenced by some anthropometric variables,the combination of stroke length and stroke frequency is very much a function of swimmers anthropometric characteristics (3). Duche et al. (2) reported that there is a strong correlation between anthropometry (height,upper limb length,bi-iliac diameter) and 50-m,100-m and 400-m in young male swimmers. Knechtle et al. (5) indicated that swimming race performance was inverse related with anthropometry in elite ultra-endurance swimmers. The above-mentioned studies generally were conducted with adolescents,pre-pubescents and elite swimmers. There is limited information about amateurs and adult competitive swimmers. Hence,the purpose of this study was to investigate the relationship between 25-m swimming performance,anthropometric properties and isokinetic knee muscle strength in amateur Turkish sprint swimmers. METHODS: Seventeen 18-24 year old amateur swimmers (n=13 males,mean age=20.0 ± 2.1 years;n=4 females,mean age=21.5 ± 1.7 years) volunteered to participate in this study. All athletes were member of the same team who were engaged to the swim training at least for 4 years. Following the 5-min warm up session,each participant performed three submaximal trials for familiarization and warm-up purposes,and then five maximal trials at three angular velocities: 60,120,and 180ᵒ/s. A 30-s time interval was provided between familiarization and test session,whereas a 2-min rest period was given between each test velocity. A 25-m swimming performance was recorded in semi-olympic swimming pool,under race conditions. RESULTS: There was a statistically significant inverse relationship between height,body mass,BMI,and swimming performance (p<0.01). There was no significant relationship between H/Q ratio and 25-m swimming performance (p>0.05). Conclusion: In conclusion,the lower limb muscle strength is as important as upper limb muscle strength and a combination of lower limb muscle strength and anthropometric variables are important for sprint swimming performance. The H/Q ratios were not significant related with 25-m swimming performance;however,the H/Q strength ratios of the participants were higher than the other study,which conducted with different sports (1,4,7).
