To examine the effects of a six week plyometric training program on selected physiological and physical fitness parameters, twenty four basketball players (14-18 yrs.) were utilized to perform anaerobic power and anaerobic capacity tests. In addition, subjects performed a vertical jump, standing long jump, 40 yard dash and one repetition maximum (1RM) squat. The subjects were randomly placed in an experimental group or control group, and the groups were randomly designated as experimental or control group. Before the treatment was given, a pre-test was conducted for both groups. Following the six week treatment, the subjects were tested once more on the previously mentioned tests. Following treatment the vertical jump (cm) and standing long jump of the plyometric training group increased (p $<$.05). Also, after treatment the vertical jump in kilograms meter/seconds was higher for the plyometric group when compared to the control group (130.3 vs 120.0 kgm/s). A significant change was seen in the 1RM squat for both groups (p $<$.05), with the experimental group increasing from 75.3 to 96.3 kg, while the control group increased from 81.1 to 96.0 kg. No significant effect of plyometric training on 1RM squat was seen. The experimental group decreased in the 40 yard dash time from 5.3 to 5.1 seconds and the control group decreased from 5.3 to 5.2 seconds. However, these changes were not statistically significant. Post-treatment anaerobic power (watts) for both groups was significantly different (p $<$.01). The experimental group increased from 559.3 to 619 watts and the control group increased from 516.9 to 579.7 watts. Also, a significant change was seen in the mean anaerobic power (watts/kg) for both groups after treatment (p $<$.01) with the experimental group increasing from 7.65 to 8.37 w/kg, while the control group increased from 6.97 to 7.79 w/kg. No / significant effects of plyometrics on anaerobic power was observed. Post-treatment anaerobic capacity (w/kg) for both groups was significantly different (p $<$.01). After treatment, post anaerobic capacity (watts) increased in the experimental group from 466.6 to 501.5 watts and for the control group from 414.3 to 456.2 watts. Also, following treatment there was a significant change in the mean anaerobic capacity (w/kg) for both groups (p $<$.05) with the experimental group increasing from 6.4 to 6.8 w/kg, while the control group increased from 5.6 to 6.2 w/kg. No significant plyometrics effect on anaerobic capacity was demonstrated. The results reveal that the plyometric training administered in this investigation can significantly improve the vertical jump and standing long jump abilities. Furthermore, the findings of this study suggest that plyometric training does not elicit alterations either improving leg muscle strength or in improving power output as measured by the WnAT compared to the control group. / Source: Dissertation Abstracts International, Volume: 51-02, Section: A, page: 0446. / Major Professor: Robert Rider. / Thesis (Ph.D.)--The Florida State University, 1990.
