Does Performance of Hang Power Clean Differentiate Performance of Jumping, Sprinting, and Changing of Direction?

Abstract

The primary purpose of this study was to investigate whether the athlete who has high performance in hang power clean, a common weightlifting exercise, has high performances in sprinting, jumping, and changing of direction (COD). As the secondary purpose, relationships between hang power clean performance, maximum strength, power and performance of jumping, sprinting, and COD also were investigated. Twenty-nine semiprofessional Australian Rules football players (age, height, and body mass [mean +/- SD]: 21.3 +/- 2.7 years, 1.8 +/- 0.1 m, and 83.6 +/- 8.2 kg) were tested for one repetition maximum (1RM) hang power clean, 1RM front squat, power output during countermovement jump with 40-kg barbell and without external load (CMJ), height of CMJ, 20-m sprint time, and 5-5 COD time. The subjects were divided into top and bottom half groups (n = 14 for each group) based on their 1RM hang power clean score relative to body mass, then measures from all other tests were compared with one-way analyses of variance. In addition, Pearson's product moment correlations between measurements were calculated among all subjects (n = 29). The top half group possessed higher maximum strength (P < 0.01), power (P < 0.01), performance of jumping (P < 0.05), and sprinting (P < 0.01). However, there was no significant difference between groups in 5-5 COD time, possibly because of important contributing factors other than strength and power. There were significant correlations between most of, but not all, combinations of performances of hang power clean, jumping, sprinting, COD, maximum strength, and power. Therefore, it seems likely there are underlying strength qualities that are common to the hang power clean, jumping, and sprinting.

Relationships between jump and sprint performance in first-class county cricketers

“…The findings of this study are similar to those reported by Bosco et al 8 , and Hori et al 9 who found strong and moderate inverse relationships of r = -0.93 (p<0.01) between 30 m and CMJ and r = -0.69 (p<0.01) between 20 m and CMJ performances, respectively. The correlations in this study are not as strong as those reported by Bosco et al 8 although the subjects used in the earlier study were a mixed group of male and female jump athletes which may have increased the range of values attained.…”

“…2 To the author's knowledge, no previous research has been conducted in cricketers to allow for a comparison of sprint times tested over the same distances presented here, but the 20 m sprint times attained by the subjects in the present study (3.05 ± 0.11 s) were similar to those reported for semiprofessional Australian Rules football players 9 , as mentioned earlier, and to those of young well-trained footballers. 6,10 However, the international football players in the study by Wisloff et al 5 displayed much greater CMJ height (56.4 ± 4.0 cm), despite similar 20m sprint times (3.00 ± 0.30 s).…”

“…The correlations in this study are not as strong as those reported by Bosco et al 8 although the subjects used in the earlier study were a mixed group of male and female jump athletes which may have increased the range of values attained. Hori et al 9 used subjects with similar age and anthropometric characteristics to the present study, with the mean values for 20 m sprint time and CMJ height (3.17 s and 41.5 cm) similar to those reported in the present study (3.05 s and 42.8 cm).…”

“…It was hypothesised that the relationship between jump height and sprint time would demonstrate a strong correlation, similar to that previously reported by Hori et al 9 , who used subjects with similar age and anthropometric characteristics to the present study. It was also hypothesised that CMJ height and sprint time would demonstrate a stronger correlation than depth drop jump (DDJ)-reactive strength index (RSI) and sprint time due to type of SSC action.…”

“…For example, Bosco et al 8 found a very strong inverse relationship between CMJ height and 30 m sprint time (r = -0.93, p<0.01), similar to the correlation between the same variables found by Hori et al 9 (r = -0.69, p<0.01). Lopez-Sigovia et al 10 found an inverse correlation between CMJ height and 20 m sprint time of r = -0.54 (p<0.05), and Requena et al 11 found a correlation between the same variables of r = -0.47 (p<0.05).…”
