“…It has already been shown that team sport in-season strength and power intervention can lead to an improvement in CoD performance (30). Moreover, studies have shown that unilateral training was more suitable for development of CoD speed compared with bilateral strength and power training (35). This indicates that CoD ability can be developed with movements that are not specific to the ability itself.…”

Ujaković, F, and Šarabon, N. The effects of workload difference between limbs in plyometric and strength exercises in reducing asymmetry in change of direction ability during basketball season. J Strength Cond Res XX(X): 000–000, 2023—The topic of interlimb asymmetries has recently been extensively investigated; despite that, intervention for purpose of reducing them have been narrowly examined. The present study investigated the effects of maximal strength and plyometric resistance training program with 3:1 workload ratio (nondominant to dominant side) on change of direction deficit (CoDdef) asymmetry during the basketball season. Thirty-six highly trained male basketball players (19.3 ± 4.9 years) from different age categories (U-17, U-19, and senior) were divided into 2 groups: the control group (n = 18) and the intervention group (n = 18). The intervention group performed once-a-week training that consisted of strength (Bulgarian split squats) and jumping (single-leg countermovement jumps [SLCMJs]) part in which nondominant-to-dominant workload ratio was 3:1 during the 8-week period. Preintervention and postintervention testing included single-leg isometric squat, SLCMJ, 10-m sprint, and 505 test. Analysis of covariance results showed a statistically significant difference with large effect size (p < 0.05; η 2 = 0.26) when preintervention asymmetry was included as covariate. Post hoc analysis showed a statistically significant decrease in mean CoDdef asymmetry between preintervention (11.88%) and postintervention (4.47%) testing (p < 0.01, effect size [ES] = −1.37). Isometric squat strength increased on nondominant side in the intervention group (p < 0.05; ES = 0.77). No other performance or asymmetry variable showed significant change. In conclusion, a 3:1 workload of nonspecific movement task in favor of nondominant limb is an effective training strategy to reduce CoDdef asymmetry during basketball season.

“…Athletes who conducted BSS maintained less than 15% difference in the muscular strength of the two legs and showed improved sprint time [20]. BSS is thought to minimize the negative effects of the difference in power and speed on acceleration between the balanced legs during sprints [21,22]. Various kinematic and EMG studies have been conducted to understand the differences in movement characteristics and activity of corresponding muscles during squat and BSS [21,23,24].…”

The purpose of this study was to compare the effects of box height on muscle activity of the ipsilateral erector spinae and gluteus maximus of the dominant leg during the Bulgarian split squat (BSS) exercise. A total of 21 healthy male participants were selected for this study. The participants repeated the Bulgarian split squat three times each on boxes of tibia height and half-tibia height. Surface EMG activity was recorded in the erector spinae and gluteus maximus for five seconds as the knees touched the mat and ascended during the Bulgarian split squat. Maximal voluntary isometric contraction (MVIC) calculated through the manual muscle test was used to normalize EMG activity. A paired sample t-test was conducted to evaluate the changes in the muscle activity of the erector spinae and gluteus maximus between box heights, and a p-value less than 0.05 was considered statistically significant. Although the EMG activity levels of the erector spinae and gluteus maximus were higher during BSS on a box of tibia height, the differences in muscle activity were not statistically significant (p>0.05). The muscle activity levels of the erector spinae and gluteus maximus were lower and similar, respectively, during Bulgarian split squat on a box of half-tibia height compared with a box of tibia height. Thus, it is recommended that BSS be conducted on boxes with shorter heights.
