Relationship between Advanced Glycation Endproducts and Muscle Strength and Lifestyle Habits in Young People

本研究の目的は，若年成人における終末糖化産物（AGEs）と身体機能および生活習慣の関係を検討することである．若年成人30名（男性15名，女性15名）を対象に，AGEs，握力，膝関節屈曲伸展トルク，総合的骨密度指数，一週間の歩数を測定し，健康度・生活習慣診断検査（DIHAL.2）を行った．統計解析は，Pearsonの積率相関係数，Spearmanの順位相関係数，χ2検定を行った．相関分析の結果，体重（r=-0.408, P=0.025），右最大握力（ρ=-0.480, P=0.007）, 左最大握力（ρ=-0.408, P=0.025）, 右膝関節最大伸展トルク（r=-0.554, P=0.002），左膝関節最大伸展トルク（r=-0.534, P= 0.002），精神的健康度（ρ=0.493, P=0.006）においてAGEsと相関を認めた．考察と結論：AGEsの蓄積予防には若年者より筋力増強を中心とした運動と生活習慣の見直しが重要であると考える．departmental bulletin pape

The effects of curl-up exercise using a Swiss ball

〔目的〕スイスボールを用いたカールアップ運動の効果は，股関節屈曲位のカールアップ運動において安定面と不安定面の運動を筋電図解析により比較した報告がある．本研究の目的は，ボールを用いた股関節中間位のカールアップ運動における腹筋の筋活動を調べ，腹筋群の効果的な筋力増強を検討することである．〔方法〕対象は，健常成人男性13名とした．方法は，股関節屈曲位，中間位，ボール上の中間位での3条件の開始姿勢から肩甲骨下角を離床する体幹屈曲（カールアップ）運動を保持している間の腹直筋，外腹斜筋，大腿直筋，大腿二頭筋，前脛骨筋，腓腹筋の表面筋電図を記録し，3条件での筋活動量を比較した．〔結果〕屈曲位条件と中間位条件での筋活動量の比較は有意差を認めなかった．しかし，中間位ボール条件は，他の2条件と比較して腹直筋が1.5～2.0倍，外腹斜筋が2.5～3.0倍，大腿直筋が約6倍，前脛骨筋が約4倍の筋活動の増加を認めた．〔考察〕スイスボールでの股関節中間位のカールアップ運動は，不安定な表面で胸郭および骨盤の回旋・傾斜運動を制御するための協調的な筋活動と筋張力の増大に効果的であることが期待できる．departmental bulletin pape

Introduction of the Neurodynamic Examination and Treatment Learned through the International Study Visit in the University of Colorado Physical Therapy Program

The purpose of this report is to introduce, by using the example of one patient with a history of low back pain and associated radiating pain, the examinations and interventions that focus on nerve mobilization and to describe occurrences of the nerve during body movement based on neurodynamics. The patient in this case presented with a history of low back pain and calf pain. Neurodynamics were examined using the straight leg raise (SLR) and slump tests. The results from the examination showed the patient’s symptoms could be classified as peripheral nerve sensitization caused by nerve root or nerve trunk irritation. The neurodynamic sliding technique using “straight leg sliders on supine” was provided by a physical therapist. Through the intervention, the left SLR angle at onset of calf pain increased from 59° to 79°. The findings of this study suggest that neurodynamic examination and treatment techniques can be useful in managing and treating patients with low back pain and associated radiating pain in Japan.departmental bulletin pape

Differences in the motion of typically developing children aged 4–6 years putting on trousers in a standing position

This study was designed to assess differences in the motion of putting on trousers in a standing position in typically developing children aged 4–6 years, and to find a relation between it and single-leg standing. 　Participants in this study were 50 typically developing children (28 boys and 22 girls; 4.5±0.4 years, 5.5±0.3 years, 6.6±0.3 years). They performed two tasks: 10 s single-leg standing and putting on trousers in a standing position. 　Based on the motion characteristics, the motions of putting on trousers were classified three types. Compared to types 1 and 2, type 3 showed that participants flexed their trunk, grasped the waistline of the trousers near the support leg knee, and fixed the trousers and extended swing leg to fit the trousers. These motion characteristics decreased the total time, path length, and anterior-posterior（AP）maximum displacement while putting on trousers. Moreover, the age increased as the type changing from 1 to 3. When standing on a single leg, the single-leg standing time increased, as did the path velocity, the AP and medial-lateral direction velocity and maximum displacement decreased as the type changing from 1 to 3. 　These results suggested that the three types motion of putting on trousers in a standing position matured by age for typically developing children aged 4–6 years. The types were related with the ability to stand on a single leg.departmental bulletin pape
