Correlations between baseline and changes after 3 months in MTH, SMI, walking speed, and knee extensor strength. A: correlation for MTH, B: correlation for SMI, C: correlation for walking speed, D: correlation for knee extensor strength. Open circles: the control group, filled circles: the moderate blood flow restriction (KAATSU RT) group. Dotted line: a regression line in the control group, continuous line: a regression line in the KAATSU RT group. *: Significant tendency in the KAATSU RT group (p < 0.1), #: Significance in the control and the KAATSU RT group (p < 0.05), †: Significance in the control group (p < 0.05).
