[Purpose] We focused on skeletal muscle mass index, one of the biomarkers of sarcopenia, and investigated the association between skeletal muscle mass index and the parameters of lung function and respiratory muscle strength. [Participants and Methods] After applying the exclusion criteria, we included, in this cross-sectional study, 120 community-dwelling older adults aged ≥65 years who required long-term care/support and underwent ambulatory rehabilitation under the long-term care insurance system in Japan. We measured the skeletal muscle mass index, forced vital capacity, forced expiratory volume in 1 second, peak expiratory flow rate, maximum expiratory pressure, and maximum inspiratory pressure. The data were analyzed using Pearson correlation coefficient and multiple regression analysis. [Results] The skeletal muscle mass index was positively correlated with only maximum expiratory pressure for both male and female participants by Pearson’s correlation coefficient. With the skeletal muscle mass index as a dependent variable, only the maximum expiratory pressure was significant for both male and female participants by the multiple regression analysis. [Conclusion] Therefore, the findings of this study suggested that compared with lung function tests, maximum expiratory pressure, which is an indicator of respiratory muscle strength, is related to muscle mass. Maximum expiratory pressure might be the most useful indicator for sarcopenia.

[Purpose] The aim of this study was to compare immediate effects between new medical stretching (NMS) and conventional medical stretching (CMS) techniques on Hamstrings flexibility. [Subjects and Methods] Thirteen healthy adult males, with finger floor distance (FFD) less than zero centimeter, without known musculoskeletal and neurological impairment in spine or lower extremities, were included. The subjects were randomly allocated to two groups. The subjects were instructed to perform NMS and CMS (hold for 30 seconds once, twice for each side of lower extremity) for both sides (total two minutes, only one session for one day). The interval between the two techniques was one week. FFD was measured with digital standing trunk flexion meter at the pre-intervention and post-intervention of both techniques. [Results] The mean values of FFD improved at the post-interventions of both techniques. The tests of within subject effects indicated that the main effect of treatment was not significant but the main effect of time was significant and the interaction of treatment and time was also significant. [Conclusion] The results of this study indicated that both medical stretching techniques were effective on Hamstrings flexibility immediately after the intervention and NMS technique was more effective on improving flexibility.

Pelvic floor muscle training has been reported to be effective in preventing and improving urinary incontinence. Patients must learn to perform pelvic floor muscle contractions without pushing down the pelvic floor by contracting other muscle groups. This study aimed to determine the effect of maximal-effort contraction of the hip adductor and abductor muscles on the pelvic floor of young, healthy women. For these experiments, 23 healthy nulliparous women performed unilateral maximal-effort isometric contractions of the abductor and adductor hip muscles in a supine position. Simultaneously, the movement of the bladder’s posterior surface was measured using an ultrasonic imaging device. The displacement of the bladder base during maximal-effort contraction of the hip adductor/abductor muscles was calculated based on changes in the distance between the abdominal wall and the bladder base at rest. The results demonstrated that the bladder base significantly descended during maximal-effort isometric contraction of hip adduction/abduction. The maximal-effort isometric hip adduction/abduction muscle strength positively correlated with bladder base descent. These results indicated that isometric contraction of the hip adduction/abduction muscles under maximum effort pushed the pelvic floor downward. In pelvic floor muscle training, when the adductor and abductor muscles of the hip joint are contracted with maximum effort, the pelvic floor muscles cannot learn contraction and may inhibit movement.

[Purpose] This study investigated the effects of co-contraction resistance exercises of the transverse abdominal and pelvic floor muscles in middle-aged females with stress urinary incontinence. [Participants and Methods] We included 32 females with stress urinary incontinence and divided them into two groups: the inner muscle training group and the pelvic floor muscle group. The thickness of the transverse abdominal muscle was measured during four tasks: (1) rest, (2) maximum contraction of the transverse abdominal muscle, (3) maximum contraction of the pelvic floor muscle, and (4) maximum co-contraction of the transverse abdominal and pelvic floor muscles. In the latter three tasks, measurements were obtained while the participants performed resistance movements using a Thera-band®. A home program was conducted in both groups, and the intervention lasted for 8 weeks. [Results] The cure rates for SUI were 87.5% and 68.8% in the inner muscle training and pelvic floor muscle groups, respectively. After the intervention, the thickness of the transverse abdominal muscle significantly increased in the inner muscle training groups performing maximum co-contraction of the transverse abdominal and pelvic floor muscles and maximum contraction of the transverse abdominal muscle. [Conclusion] Inner muscle training exercises are more effective than pelvic floor muscle exercises in improving inner muscle function and urinary incontinence in middle-aged females.

[Purpose] The Asian Working Group for Sarcopenia (AWGS) criteria were recently updated. However, whether these changes would result in a difference in sarcopenia prevalence was unclear. We therefore focused on Japanese older adults who required long-term care/support and determined the differences in sarcopenia prevalence between the new and old criteria. [Participants and Methods] This cross-sectional study included 161 Japanese older adults aged ≥65 years who required long-term care/support along with ongoing daycare. Handgrip strength, usual gait speed, and skeletal muscle mass index were measured. We analyzed the difference in sarcopenia prevalence between the 2019 and 2014 AWGS criteria using the McNemar test. [Results] The overall sarcopenia prevalence rates were 60.2% and 53.4%, and the prevalence rates of sex-specific sarcopenia were 63.6% and 55.7% among males and 56.2% and 50.7% among females when the 2019 and 2014 AWGS criteria were used, respectively. Overall, males exhibited a significantly higher prevalence with the new than criteria than with the old. [Conclusion] With the 2019 AWGS criteria, more older males who required long-term care/support were diagnosed as having sarcopenia. Conversely, the sarcopenia diagnosis in females statistically remained unchanged. Thus, a mismatch might exist between the two criteria regarding sarcopenia prevalence in males.

[Purpose] The purpose of this this study was to examine the immediate effects of intervention of proprioceptive neuromuscular facilitation (PNF), neuromuscular joint facilitation (NJF) and NJF+pelvic floor muscle (PFM) exercise. [Subjects] Thirteen young people (5 males, 8 females) who had chronic low back pain on one side for more than 6 months. [Methods] Subjects were asked to lie on their sides with the painful side uppremost. The subjects received PNF, and NJF, NJF+PFM exercise treatments. The changes in the cross-sectional area of the multifidusmuscle were measured using ultrasonography. [Results] The cross-sectional area of the multifidus muscle of NJF+PFM group showed the largest increases on both the sides with and without pain. [Conclusion] Our results show that chronic low back pain can be improved by a combination of PFM exercise and the NJF pattern.
