“…Measurements of subjective fatigue using a VAS suggested that the recovery of subjective fatigue was enhanced in the MBT group as compared to the CON group (Figure ). This is similar to the results of our previous study . The new findings of this study involve physiological measurements and were as follows: (a) Isometric knee flexion torque recovered faster in the MBT than in the CON group (Figure ) and (b) hardness in some muscles in the lower leg and thigh would recover faster in the MBT group than in the CON group (Figure ).…”

“…In the present study, we demonstrated that following a marathon run, wearing unstable rocker shoes facilitated recovery from muscle hardness as well as muscle weakness in addition lessened subjective fatigue . Wearing such shoes would be valuable for both athletes and recreational runners, because daily wearing of MBT shoes requires no additional time or effort such as eating a special diet or drinking custom liquids that induces recovery .…”

“…Thus, 11 subjects completed all measurements for both the MBT and CON groups (n=11), respectively). We did not utilize a placebo shoe group, as our previous study suggested that that there was no difference in recovery of subjective fatigue between the “free shoe choice” group of subjects and a placebo flat‐sole shoe group . About 64% subjects (7/11 in the MBT group, 9/14 in the CON group) had participated in full‐marathon race once or twice before participating in this experiment.…”

We recently reported that wearing unstable rocker shoes (Masai Barefoot Technology: MBT) may enhance recovery from marathon race-induced fatigue. However, this earlier study only utilized a questionnaire. In this study, we evaluated MBT utilizing objective physiological measures of recovery from marathon-induced muscle damages. Twenty-five university student novice runners were divided into two groups. After running a full marathon, one group wore MBT shoes (MBT group), and the control group (CON) wore ordinary shoes daily for 1 week following the race. We measured maximal isometric joint torque, muscle hardness (real time tissue elastography of the strain ratio) in the lower limb muscles before, immediately after, and 1, 3, and 8 days following the marathon. We calculated the magnitude of recovery by observing the difference in each value between the first measurement and the latter measurements. Results showed that isometric torques in knee flexion recovered at the first day after the race in the MBT group while it did not recover even at the eighth day in the CON group. Muscle hardness in the gastrocnemius and vastus lateralis showed enhanced recovery in the MBT group in comparison with the CON group. Also for muscle hardness in the tibialis anterior and biceps femoris, the timing of recovery was delayed in the CON group. In conclusion, wearing MBT shoes enhanced recovery in lower leg and thigh muscles from muscle damage induced by marathon running.

“…Overall muscular fatigue was quantified by asking the subject to place a mark on a 12-cm visual analog scale with anchors at 0 cm (comfortable with no fatigue) on the left and 12 cm (too exhausted to do anything) on the right, as done previously. 17,19 The distance of the mark from the left was quantified as a percentage of the line length.…”

Study Design Randomized controlled trial. Background Postexercise recovery techniques are widely used, but little research has examined their effectiveness. Objectives To examine the effectiveness of massage and pneumatic compression on recovery from a 161-km ultramarathon. Methods Participants in the 2015 161-km Western States Endurance Run were randomized to a 20-minute postrace intervention of massage, intermittent sequential pneumatic compression, or supine rest. Each subject completed two 400-m runs at maximum speed before the race and on days 3 and 5 after the race, and also provided muscle pain and soreness ratings and overall muscular fatigue scores before and for 7 days after the race. Results Among the 72 runners who finished the race and completed the study, comparison among intervention groups revealed no significant group or interaction effect on 400-m run time, but there was a significant (P<.0001) time effect. Immediately posttreatment, massage resulted in lower muscle pain and soreness ratings compared with the supine-rest control condition (P<.0001), while both massage (P<.0001) and pneumatic compression (P<.01) resulted in lower overall muscular fatigue scores compared with the control group. There were no significant differences between groups in any outcome 1 to 7 days after the race. Conclusion Single 20-minute sessions of postrace massage and intermittent sequential pneumatic compression provide some immediate subjective benefit. There is no evidence, however, that such treatments provide extended subjective or functional benefits of clinical importance. The trial was registered at www.clinicaltrials.gov (NCT02530190).
