Subclaims¶

q2 i? Hearing-impaired volleyball players who added 8-week plyometric training showed significant pretest-posttest differences versus controls in overall stability R, medial lateral R and overall stability L (p <0.05). → Ersin Nacaroglu & Onder Karakoc 2018

Independent Samples T-test comparison of pretest-posttest differences between the experimental (plyometric plus volleyball) and control (volleyball only) groups, reported in Findings Table 6. Overall Stability-R difference was 0.39±0.46 vs -0.03±0.21 (t=2.897, p=0.008), Medial Lateral-R -0.13±0.59 vs 0.51±0.63 (t=-2.579, p=0.017), Overall Stability-L 0.46±0.45 vs 0.07±0.34 (t=2.369, p=0.027). The article prints no effect sizes.

"For the experimental and control groups, statistical significance was found in the values of overall stability R, medial lateral R, and overall stability L in comparing the mean values of the pretest values and the post-test values of the static balance measurement parameters (p <0.05)."

Discussion¶

Related Claims¶

• In the control group, only medial lateral R changed significantly from pretest to post-test; the other five static balance parameters showed no significant change — related
• Within the experimental group, pretest-post-test gains were significant for overall stability R, overall stability L and anterior posterior L, but not for anterior posterior R or medial lateral R — related
• No significant between-group differences emerged for anterior posterior R, anterior posterior L or medial lateral L static balance parameters — related
