Plyometrics is a popular training modality for basketball players to improve power and change-of-direction speed. Most plyometric training has used sagittal-plane exercises, but improvements in change-of-direction speed have been greater in multidirection programs.

Purpose:

To determine the benefits of a 6-wk frontal-plane plyometric (FPP) training program compared with a 6-wk sagittal-plane plyometric (SPP) training program with regard to power and change-of-direction speed.

Methods:

Fourteen female varsity high school basketball players participated in the study. Multiple 2 × 2 repeated-measures ANOVAs were used to determine differences for the FPP and SPP groups from preintervention to postintervention on 4 tests of power and 2 tests of change-of-direction speed.

Results:

There was a group main effect for time in all 6 tests. There was a significant group × time interaction effect in 3 of the 6 tests. The SPP improved performance of the countermovement vertical jump more than the FPP, whereas the FPP improved performance of the lateral hop (left) and lateral-shuffle test (left) more than the SPP. The standing long jump, lateral hop (right), and lateral-shuffle test (right) did not show a significant interaction effect.

Conclusions:

These results suggest that basketball players should incorporate plyometric training in all planes to improve power and change-of-direction speed.

Given the key role coaches play in the experience of athletes, understanding the relationship between coach leadership styles and positive youth development (PYD) is crucial. This study examined the relationship of coach transformational leadership (TFL) to PYD. Athletes (n = 203) nested within 28 competitive youth basketball teams completed questionnaires about their coaches’ TFL, and two measures related to their own PYD – Youth Experiences for Sport, measuring PYD specific to the sport context, and a measure to assess the 5Cs (Competence, Confidence, Connection, Character, and Caring). Due to the nested nature of athletes within team and significant intraclass correlations, the predictive contribution of team and individual level perceptions of TFL was assessed with multilevel modeling. Individual and team perceptions of coach TFL significantly predicted 59% of the YES-S variance. In addition to team and individual main effects, a significant cross-level interaction predicted 20% of a player’s development of the 5Cs. Thus, athletes reporting above average coach TFL on teams reporting above average coach TFL reported the greatest 5C development. These results provide additional support for TFL as an avenue to foster PYD. Findings elucidate transformational coach behaviors that are related to positive experiences in youth sport and the 5Cs.

High levels of physical inactivity are evident among many American children. To address this problem, providing physical activity (PA) during the school day within the CSPAP framework, is one strategy to increase children’s PA. Thus, the purpose of this study was to examine the effects of a classroom-based PA program on children’s PA. Two hundred and ten students from one school participated in TAKE 10! for 12 weeks. All students wore pedometers and a sample of 64 students wore accelerometers for 4 days during week 1 (baseline), week 8 (midintervention), and week 12 (end-intervention). Data were analyzed using repeated-measures ANOVA. The results showed that students’ daily in-school step counts increased by 672 steps from baseline to midintervention (P < .001). Students’ moderate-to-vigorous intensity PA (MVPA) increased by approximately 2 minutes from baseline to end-intervention (P < .01). In conclusion, participating in TAKE 10! helps children strive toward the goal of recommended daily MVPA.

The purpose of this study was to describe the developmental stepping movements of 5 infants with Down syndrome who participated in a pediatric strength intervention. Pretest and posttest data were collected with the Hawaii Early Learning Profile Strands, Battelle Developmental Inventory, and specially designed gait analysis. An 8-week individualized pediatric strength intervention was implemented according to theoretical principles of progressive interactive facilitation (Cowden, in press). Posttest data and the Snyder-McLean (1987) intervention developmental quotient suggested an increase in the subjects’ rates of motor development during intervention as compared to their lifetime rates prior to intervention. One subject showed increased rate and distance, 2 subjects acquired independent upright locomotion, and 1 subject established independent sitting movements and creeping patterns. One subject was unable to complete the study.
