Background and objective: Adolescence is a period when balance and coordination decrease as a result of rapid musculoskeletal growth. These changes may affect various sports-specific skills, including balance. This study aimed to examine the changes in balance performance and basketball passing speed in male youth basketball players following six weeks of balance training performed on unstable versus stable surfaces. Methods: Twenty-five male basketball players, mean age 15.53 ± 0.57 years, participated in balance training on different surfaces (unstable surface (US, n = 13); stable surface (SS, n = 12)) for six weeks (2 days/week; 35 to 50 min/day, incrementally). Their physical characteristics, passing skills (passing accuracy and speed test) and balance performance (Y-Balance Test and The Closed Kinetic Chain Upper Extremity Stability Test) were measured. Results: The improvement rates for passing accuracy (effect size (ES) = 0.86, moderate, P < 0.001), lower extremity (ES right = 0.94, moderate, P < 0.001; ES left = 0.88, moderate, P < 0.001) and upper extremity (ES right = 1.01, moderate, P < 0.001; ES left = 0.94, moderate, P < 0.001) balance scores, upper extremity stability test power (ES = 0.89, P ≤ 0.001) and the normalized scores (ES = 1.20, moderate, P < 0.001) of the US group were higher than those of the SS group. Passing speed significantly increased only in the US group (P < 0.028). Conclusion: A multi-dimensional surface training model improved balance performance and passing accuracy skills compared to a stable surface training model for male basketball players. US balance training may be used as a complementary training model to increase dynamic balance and passing accuracy skills for male basketball players.

Balance Ability

BACKGROUND: To avoid injuries in basketball players, they are recommended to pay more attention to improve their body balance. Therefore new training methods and equipment need to be devised. This study examined the effects of an 8-week basketball-specific proprioception training program while using a new developed one plane instability balance board during warm-up for improving balance ability in basketball players. Players who obtained basketball-specific balance training were compared to a control group. METHODS: Thirty-one male university basketball players (age: 21.35, SD = 0.605 years; height: 190.97, SD = 1.88; body mass: 86.95, SD = 2.61) participated in this study. Seventeen participants were assigned to the basketball-specific 8-week balance training group (BTG) while 14 participants served as a control group (CG). Both groups were tested with the Y balance test (YBT) and postural stability test (PST) at baseline and 8 weeks later. RESULTS: The results indicate significant improvements in the overall YBT for both legs in BTG, but not in CG. However, no group differences were found for dynamic balance performance, but static balance (i.e., postural stability) differed between groups after 8 weeks. A statistically significant moderate inverse correlation was computed between the total score of YBT and the total score of the overall stability index (r=-0.404; p= 0.041). CONCLUSIONS: An 8-week basketball-specific proprioception training program with a single-plane instability balance platform improved balance ability (Y balance test and postural stability test) of basketball players.

Abstract Objective The Brief-Balance Evaluation Systems Test (Brief-BESTest) is a comprehensive, reliable, and valid balance test that provides valuable information to guide balance training in people with chronic obstructive pulmonary disease (COPD). Its clinical interpretability is, however, currently limited, as cutoff points to identify clinically relevant changes in people with COPD after pulmonary rehabilitation are still lacking. This study aimed to establish the responsiveness and minimal clinically important difference (MCID) for the Brief-BESTest in people with COPD after pulmonary rehabilitation (PR). Methods A secondary analysis of data from 2 previous studies was conducted. The modified British Medical Research Council (mMRC) dyspnea scale, the 6-Minute Walk Test (6-MWT), and the Brief-BESTest (0–24 points) were collected in people with COPD pre/post a 12-week PR program including balance training. The MCID was computed using anchor- and distribution-based methods. Changes in the 6-MWT and the mMRC were assessed and used as anchors. The pooled MCID was computed using the arithmetic weighted mean (2/3 anchor- and 1/3 distribution-based methods). Results Seventy-one people with COPD [69 years (SD = 8); 76% male; FEV1 = 49.8%predicted (SD = 18%)] were included. There was a significant improvement in the Brief-BESTest after PR [mean difference = 3 points (SD = 3)]. Significant correlations were found between the Brief-BESTest and the mMRC (r = −.31) and the 6-MWT (r = .37). The pooled MCID was 3.3 points. Conclusion An improvement of at least 3 points in the Brief-BESTest in people with COPD will enhance the interpretability of PR effects on balance performance of this population and guide tailored interventions. Impact The Brief-BESTest outcome measure is comprehensive, easily administered, and simple to interpret in clinical practice. This study represents a significant contribution toward the clinical interpretation of changes in balance in people with COPD following PR.

Abstract Background Cross-sectional studies have shown that balance performance can be challenged by the level of task difficulty (e.g., varying stance conditions, sensory manipulations). However, it remains unclear whether the application of different levels of task difficulty during balance training (BT) leads to altered adaptations in balance performance. Thus, we examined the effects of BT conducted under a high versus a low level of task difficulty on balance performance. Methods Forty male adolescents were randomly assigned to a BT program using a low (BT-low: n = 20; age: 12.4 ± 2.0 yrs) or a high (BT-high: n = 20; age: 12.5 ± 2.5 yrs) level of balance task difficulty. Both groups trained for 7 weeks (2 sessions/week, 30–35 min each). Pre- and post-training assessments included measures of static (one-legged stance [OLS] time), dynamic (10-m gait velocity), and proactive (Y-Balance Test [YBT] reach distance, Functional Reach Test [FRT]; Timed-Up-and-Go Test [TUG]) balance. Results Significant main effects of Test (i.e., pre- to post-test improvements) were observed for all but one balance measure (i.e., 10-m gait velocity). Additionally, a Test x Group interaction was detected for the FRT in favor of the BT-high group (Δ + 8%, p < 0.001, d = 0.35). Further, tendencies toward significant Test x Group interactions were found for the YBT anterior reach (in favor of BT-high: Δ + 9%, p < 0.001, d = 0.60) and for the OLS with eyes opened and on firm surface (in favor of BT-low: Δ + 31%, p = 0.003, d = 0.67). Conclusions Following 7 weeks of BT, enhancements in measures of static, dynamic, and proactive balance were observed in the BT-high and BT-low groups. However, BT-high appears to be more effective for increasing measures of proactive balance, whereas BT-low seems to be more effective for improving proxies of static balance.

Context: Volleyball and handball players have usually been studied collectively as “overhead athletes,” since throwing present similarities in the proximal to distal movement sequencing and upper limb joints ranges of motion. However, each sport presents specificities in the objectives when accelerating the ball and a variety of possible throwing techniques. Therefore, it is expected there may be differences in the shoulder and upper body physical performance between sports. Objective: The aim of this study was to determine if there are differences in shoulder muscle strength and upper body field performance tests between volleyball and handball athletes. Design: Cross-sectional. Methods: Ninety-nine volleyball and handball female athletes aged between 13 and 20 years were evaluated for isometric shoulder abductor and rotator strength (handheld dynamometer) and upper body field performance tests: Y Balance Test—Upper Quarter, modified Closed Kinetic Chain Upper-Extremity Stability Test, and unilateral and bilateral Seated Medicine Ball Throw. Results: Handball athletes presented greater shoulder internal rotation strength (between-group difference: 2.84; effect size 0.70), higher medial (between-group difference: 9.54; effect size 0.90), superolateral (between-group differences: 8.9; effect size 0.68), and composite scores (between-group difference 5.7; effect size 0.75) of the Y Balance Test—Upper Quarter and higher unilateral (between-group difference: 41.92; effect size 0.91) and bilateral (between-group difference: 46.11; effect size 0.83) Seated Medicine Ball Throw performance. Groups were not different for Closed Kinetic Chain Upper-Extremity Stability Test, external rotation, and abduction isometric strength. Conclusion: Our findings suggest that young female handball athletes present greater internal rotator strength and better performance in Y Balance Test—Upper Quarter and Seated Medicine Ball Throw compared to volleyball players. These differences may be related to the different demands required in the throwing movements performed in each sport and should be considered when assessing these populations.
