[Purpose] Bicycle saddle height is a critical factor for cycling performance and injury prevention. The present study compared the variance in cadence frequency after exercise fatigue between saddle heights with 25° and 35° knee flexion. [Methods] Two saddle heights, which were determined by setting the pedal at the bottom dead point with 35° and 25° knee flexion, were used for testing. The relative variances of the cadence frequency were calculated at the end of a 5-minute warm-up period and 5 minutes after inducing exercise fatigue. Comparison of the absolute values of the cadence frequency under the two saddle heights revealed a difference in pedaling efficiency. [Results] Five minutes after inducing exercise fatigue, the relative variances of the cadence frequency for the saddle height with 35° knee flexion was higher than that for the saddle height with 25° knee flexion. [Conclusion] The current finding demonstrated that a saddle height with 25° knee flexion is more appropriate for cyclists than a saddle height with 35° knee flexion.

[Purpose] This study investigated the effects of low-level laser phototherapy on hand and forearm fractures. [Subjects and Methods] This was a one-group pretest-posttest design study. We recruited 9 patients with hand or forearm fracture, and they received diode laser treatment (808 nm, 10 Hz, 60 mW). Evaluation of pain on a visual analog scale (VAS) and radiographic assessments were made pre-intervention, post-intervention, and at two weeks of follow-up. [Results] There were significant differences in VAS scores between pre-intervention and post-intervention and between pre-intervention and 2 weeks of follow up. In the radiographic assessment, the percentage of detectable cortical bridging also increased significantly after phototherapy. [Conclusions] We consider that low-level laser phototherapy is effective for human bone healing and pain relief.
