Hirono, T, Ikezoe, Taniguchi, M, Tanaka, H, Saeki, J, Yagi, Umehara, and Ichihashi, N. Relationship between muscle swelling hypertrophy induced by resistance training. J Strength Cond Res 36(2): 359-364, 2022-Muscle immediately after exercise may be metabolic stress. The accumulation of stress is considered to promote several weeks training (RT). purpose this study was determine the relationship first session RT a 6-week using ultrasonography. Twenty-two untrained young men performed knee...
Excessive stiffness of lower limb muscles is associated with sports injuries. Therefore, the identification a reliable measurement shear elastic modulus various ankle plantar flexion required to evaluate leg This study investigated at different positions.Twenty-three healthy young men (25.3 ± 3.6 years, 172.9 5.0 cm, 67.2 7.2 kg) participated in this study. The moduli including lateral gastrocnemius, medial soleus, peroneus longus, brevis, flexor hallucis digitorum longus and tibialis...
Previous history of medial tibial stress syndrome ( MTSS ) is a risk factor for relapse, which suggests that there might be some physical factors are related to development in runners with . The relationship between and muscle stiffness can assessed cross‐sectional study measures subjects , who do not have pain at the time measurement, those without purpose this was compare shear elastic modulus, an index stiffness, all posterior lower leg muscles no investigate could Twenty‐four male...
Improving muscle quality to prevent and treat dysfunction is critical. However, effective measures improve remain poorly understood. We investigated the effects of high- low-velocity resistance training (RT) on quality, mass, function before after an 8-week intervention.
Abstract Background Incorrect body weight shifting is a frequent cause of falls, and the control whole-body center mass (CoM) by segmental coordination essential during walking. Uncontrolled manifold (UCM) analysis method examining relation between variance in CoM stability. However, no prospective cohort study has thoroughly investigated how configurations to stabilize relates future falls. This explored whether was related Methods At baseline visit, 30 community-dwelling older adults...
Abstract Background A high proportion of flexor digitorum longus attachment is found at the posteromedial border tibia, which most common location medial tibial stress syndrome (MTSS). Therefore, plantar flexion strength lesser toes could be related to MTSS; however, relationship between MTSS and muscle hallux not yet evaluated due lack quantitative methods. This study investigated characteristics in runners with a history by using newly developed device measure hallux, toes, ankle. Methods...
Increased muscle stiffness of the pectoralis minor (PMi) could deteriorate shoulder function. Stretching is useful for maintaining and improving in rehabilitation sport practice. However, acute prolonged effect stretching on PMi unclear due to limited methodology assessing individual stiffness. Using shear wave elastography, we explored responses modulus over time. The first experiment (n = 20) aimed clarify change during stretching. was measured at intervals 30 s × 10 sets. second 16)...
ABSTRACT Introduction In this study we investigate whether low‐load isotonic training will elicit greater improvement in muscle strength at the same fascicle length, rather than joint angle. Methods Sixteen healthy men (24.1 ± 2.5 years of age) were randomly divided into intervention and control groups. Pre‐ posttraining maximum isometric isokinetic strengths lengths medial gastrocnemius measured. Isotonic resistance 15 ° to 30 ankle plantarflexion low intensity was conducted for 4 weeks....
[Purpose] The purpose of this study was to determine the relationship between navicular drop and plantar flexion torque first second-fifth metatarsophalangeal joints. [Subjects] Ten healthy young men participated in study. [Methods] Pearson product-moment correlation coefficient calculated [Results] Significant negative correlations were observed torques lengthened position intrinsic toe muscles, but no found neutral ankle Moreover, muscles contribute formation medial longitudinal arch....
[Purpose] The purpose of this study was to determine the functional differences plantar flexion muscles hallux and lesser toes during single leg stance by comparing postural sway in different conditioning contraction interventions. [Subjects] Thirty-four healthy, young males females participated study. [Methods] front-back right-left direction components maximal displacement velocity were measured various interventions for or lessor toes. [Results] main findings as follows: 1) component...
Backgrounds: Joint kinetic calculations are sensitive to joint centre locations. Although geometric hip and knee centre/axis generally developed, the ankle (AJC) is conventionally defined as midpoint between malleolus lateralis medialis (AJCMID) in most gait analyses. Research question: We examined positional difference of AJCMID from rotation (AJCFUN) its effect on kinetics representative human gaits. Methods: In first experiment, we calculated AJCFUN indicated location MRI 14 (seven male...
The structure of the first toe is independent that other toes, while functional difference remains unclear. purpose this study was to investigate in force generation characteristics between plantar-flexion and second–fifth metatarsophalangeal joints (MTPJs) by comparing maximal voluntary torques (MVC torque) at different MTPJs ankle positions. MVC were measured 0°, 15°, 30°, 45° dorsiflexed positions MTPJs, 20° plantar-flexed, neutral, ankle. Two-way repeated measures analyses variance with...
The peak increase in lean mass adolescents is delayed from height velocity (PHV), and muscle flexibility temporarily decreases as bones grow. If the decrease caused by elongation, relationship between exerted torque joint angle could change adolescents. purpose of this study was to investigate optimum force production due growth. Eighty-eight healthy boys were recruited for study. Isokinetic knee extension strength dominant leg recorded. outcome variable flexion when maximal produced...
Although evidence suggests that intramuscular fat infiltration may influence muscle strength, the precise mechanisms remain unclear. This study aimed to determine whether affects mechanical properties during contraction and these mediate relationship between strength. Seventy-nine healthy older women aged 75.1 ± 6.8 years were included in this study. The echo intensity (EI) of vastus lateralis (VL) was measured as an index using B-mode ultrasonography. Maximum voluntary isometric strength...
Background: Clinicians and researchers are beginning to pay attention the importance of intrinsic foot muscles (IFMs). Among IFMs, abductor hallucis (AbH) is associated with disorders. However, so far no method for assessing strength AbH has been established. In addition, previous studies have shown increased IFM activity in plantarflexed position ankle. Therefore, this study tests hypothesis that a correlation will be found between cross-sectional area (CSA) flexion torque first...
The high temperature ductility of coarse grained Mg-2.7 mol%Al and Mg-4.5 alloys has been investigated. Both showed superplastic-like elongation over 250% at 723 K. deformation is rate controlled by solute drag dislocations which often governs the creep what called Class I solid solution alloys. As for in creep, number slip systems essential. magnesium alloy only three room temperature. However, behavior appears temperature, since non-basal activated. Superplastic-like observed Mg-Al thus...
