4. Fig 3
Mean V̇o2 ± SD (in mL·kg−1·min−1) of vibration frequency and loads of older and young groups. Vibration and load significantly (P<.001) increased V̇o2. There was a significant load by group interaction effect (P<.001) between the additional loads of 20% and 40% of body mass (BM) of increased V̇o2, and there was a small significant interaction of vibration and group (P=.045).

5. Fig 4
Mean ± SD of SBP, DBP, and RPE at 2 and 4 minutes during the various vibration frequency and loads for the older and young groups. Increased loads produced a significant rise (P<.001) in SBP. DBP increased significantly (P<.001) with vibration and a larger load (40% BM). Vibration and load produced a significant increase in RPE. Abbreviations: NV, no vibration; 0% BM, no load; 20% BM, load 20% of BM; 40% BM, load 40% of BM.
