Loss of muscle strength is not only associated with loss of muscle mass, but also affected by neural factors. It is well known that facilitatory and inhibitory responses of spinal motor neurons occur with cutaneous stimulation via spinal interneurons. The purpose of this study was to examine the neural adaptations associated with low load resistance training utilizing skin cooling (SC). 10 men trained both legs and each side was randomly assigned to SC training (SC-T) and non SC training (NSC-T). Subjects performed 30 isometric ankle dorsiflexion repetitions at 35% maximum voluntary contraction (MVC) 3 times weekly for 6 weeks. The skin cooling condition was defined as when skin temperature was 25°C while repetitive resistance training was being performed. Dorsiflexor MVC significantly increased in both SC-T (n = 9) and NSC-T (n = 9) by 12.8 and 3.8%, respectively. A significant increase in root mean square of EMG (rmsEMG) was observed for 30 isometric ankle dorsiflexion repetitions in SC-T both pre- and post-training. Lower leg girths did not significantly increase post-training. Therefore, the results of this study suggest that muscle strength might increase via changes in neural activation and that SC-T may lead to greater increases in muscle strength compared with NSC-T because of improved muscle activation during resistance training with SC. Therefore, we suggest that low load resistance training with SC is an effective method to increase muscle strength.

Purpose: The purpose of this study is to evaluate hangeshashinto rinse for oral discomfort in terminally-ill cancer patients and to compare the effectiveness of hangeshashinto rinse with or without honey rinse. Methods: Patients with oral discomfort were randomized to receive either hangeshashinto rinse or hangeshashinto with honey rinse as first-line treatment. Patients performed oral rinse three to five times a day for 2 weeks. Further, oral wetness, halitosis, oral mucositis, mouth discomfort, compliance of rinse were then evaluated before and after the intervention. Results: 144 patients were enrolled during this period and 22 patients completed the study (hangeshashinto 13 / hangeshashinto with honey 9). After the intervention, oral wetness was improved, and end-tidal concentration of hydrogen sulfide was decreased in both cases. Although there was no statistically significant difference, oral discomfort by subjective and objective evaluations, also and symptom of oral mucositis were improved. Other volatile sulfur compounds decreased. Frequency of rinsing between groups receiving hangeshashinto or hangeshashinto with honey did not differ, however, the acceptability was slightly better in the honey combination group. Conclusion: Both hangeshashinto rinse and hangeshashinto with honey rinse reduced end-tidal concentration of hydrogen sulfide and improved oral wetness. Oral rinse by hangeshashinto or hangeshashinto with honey may be effective for oral discomfort in terminally-ill cancer patients.
