The purpose of this study was to compare measures of body size in two samples of youth baseball players with normative data from the United States National Center for Health Statistics (NCHS) growth charts. One sample of youth baseball players participated in a local little league. The second sample of youth baseball players were members of eight of the twelve teams participating in the 1995 Dixie Youth World Series. Normative data for the United States (NCHS) were used as comparative data. Two trained anthropometrists measured standing height, sitting height, lower limb height, upper limb length, arm girth, calf girth, tricep skinfold, and abdomen skinfold on all participants. In both samples, pitchers, short stops, and first basemen were a more highly skilled group and exhibited larger body size (greater standing height, sitting height, lower limb height, upper limb length) than children who played at other positions. The standing height of local little league players was similar to the median of reference data at ages 7, 8, and 9 years. The standing height and weight of skilled players in both samples approximated the 75th percentile for standing height and weight at ages 10, 11, 12, and 13 years. The results suggest that baseball players exhibit larger body size than the normal population at young ages. Body size may be an important criterion used by coaches to select and assign young players to certain positions.
本研究的目的是将两组青少年棒球运动员的身体尺寸测量数据与美国国家卫生统计中心(NCHS)生长图表中的标准数据进行比较。一组青少年棒球运动员参加了当地的小联盟。另一组青少年棒球运动员是参加1995年迪克西青少年世界系列赛的12支球队中8支球队的队员。美国(NCHS)的标准数据用作比较数据。两名经过培训的人体测量师对所有参与者测量了身高、坐高、下肢长度、上肢长度、上臂围、小腿围、肱三头肌皮褶厚度和腹部皮褶厚度。在两组样本中,投手、游击手和一垒手是技术更熟练的群体,与在其他位置打球的儿童相比,他们的身体尺寸更大(身高、坐高、下肢长度、上肢长度更大)。当地小联盟球员在7岁、8岁和9岁时的身高与参考数据的中位数相似。两组样本中技术熟练球员的身高和体重在10岁、11岁、12岁和13岁时接近身高和体重的第75百分位数。结果表明,棒球运动员在年轻时的身体尺寸比正常人群更大。身体尺寸可能是教练用来挑选年轻球员并将其分配到特定位置的一个重要标准。
