Static stretching (SS) is commonly performed as part of warm-up routine. However, only few previous studies have reported on the effects short-duration SS, which often used in sports field. The purpose this study was to investigate acute and prolonged 20-s SS isokinetic contraction muscle strength, range motion (ROM), shear elastic modulus.Twenty male volunteers participated study. ROM both concentric eccentric strengths were measured using a dynamometer. In addition, modulus medial...

The purpose of this study was to compare two static stretching (SS) training programs at high-intensity (HI-SS) and low-intensity (LI-SS) on passive active properties the plantar flexor muscles. Forty healthy young men were randomly allocated into three groups: HI-SS intervention group (n = 14), LI-SS 13), non-intervention control 13). An 11-point numerical scale (0-10; none very painful stretching) used determine SS intensity. stretched 6-7 0-1 intensities, respectively, both in 3 sets 60...

Muscle strain is one of the most frequent sports injuries, having rectus femoris (RF) muscle as reported preferred site quadriceps strain. The decrease stiffness could be an effective RF prevention. In recent studies, a high-intensity static stretching intervention decreased passive stiffness, though no study has investigated on effect different intensities stiffness. purpose this was to investigate three (120 vs. 100 80%). Eighteen healthy, sedentary male volunteers participated in and...

Inter-set rest intervals are essential to reduce muscle fatigue and increase the total amount of volume resistance training. Static stretching walking may blood flow promote recovery during inter-set intervals. Therefore, purpose this study was investigate effects 20 seconds static leg extension exercises on number repetitions exhaustion, volume, flexibility quadriceps (joint range motion hardness) in untrained healthy males. Fourteen healthy, men performed three different interventions...

[Purpose] The relationship between fine and gross motor function visuospatial working memory in children with autism spectrum disorder remains unclear. This study examined whether is associated or skills developmental disabilities coordination disorders. [Participants Methods] included 30 (24 boys 6 girls; mean age: 9.5 ± 2.2 years) enrolled child development support after-school daycare service centers Osaka Prefecture. Fine skills, memory, were assessed. Data analyzed using Spearman's rank...

Background: Endothelial progenitor cells (EPCs) can be used to treat ischemic disease in cell-based therapy owing their neovascularization potential. Glucocorticoids (GCs) have been widely as strong anti-inflammatory reagents. However, despite beneficial effects, side effects such impairing wound healing are commonly reported with GC-based therapy, and the of GC on function EPCs unclear. Methods: In this study, we investigated how treatment affects characteristics permission University...

The purpose of this study was to compare the duration high-intensity static stretching on flexibility and strength in hamstrings.Fourteen healthy males (20.8 ± 0.6 years, 170.7 6.5 cm, 66.4 9.9 kg) underwent for three different durations (10, 15, 20 seconds). intensity set at maximum point discomfort. To examine change strength, range motion, peak passive torque, relative muscle-tendon unit stiffness, torque isokinetic knee flexion, angle flexion were measured. evaluate a time course pain,...

The purpose of this study was to examine the time course changes in range motion and muscle-tendon unit stiffness hamstrings after two different intensities static stretching.Fourteen healthy men (20.9 ± 0.7 years, 169.1 7.5cm, 61.6 6.5kg) received stretching for 60 seconds at based on point discomfort (100%POD 120%POD) each participant, random order. To evaluate flexibility hamstrings, knee extension (ROM), passive torque end ROM, were measured pre-stretching, post-stretching, both 10 20...

A previous study reported that 3-min of high-intensity static stretching at an intensity 120% range motion (ROM) did not change the muscle stiffness rectus femoris, because overly high stress stretching. The purpose this was to examine effects a shorter duration or lower on flexibility femoris than study. Two experiments were conducted (Experiment 1 and 2). In Experiment 1, eleven healthy men underwent ROM for two different durations (1 3 min). 2, fifteen 110% ROM. shear elastic modulus...

J Strength Cond Res 35(1): 141-146, 2021-The purpose this study was to examine the effects flexibility strength calf Fourteen healthy males (age: 23.1 ± 2.6 years, height: 172.7 5.6 cm, body mass: 64.5 7.0 kg) performed 3 types respectively for 10 minutes a random order: an warm-up by pedaling cycling ergometer, doing...

The purpose of the present study was to investigate static stretching and dynamic protocol.

Abstract The purpose of the present study was to examine association between static stretching load and changes in flexibility hamstrings. Twelve healthy men received for 60 s at two different intensities based on point discomfort (100%POD 120%POD intensity), random order. To assess hamstrings, knee extension range motion (ROM). Passive torque end ROM, muscle–tendon unit stiffness were measured before after stretching. calculated from passive throughout ROM increased both ( p < 0.01)....

Vibration foam rolling (VFR) intervention has recently gained attention in sports and rehabilitation settings since the superimposed vibration with can affect several physiological systems. However, sustained effect a comparison of effects different VFR frequencies on flexibility muscle strength have not been examined. Therefore, this study, we aimed to investigate acute three 60-s sets knee flexion range motion (ROM) extensors. Using crossover, random allocation design, 16 male university...

The effects of static stretching are influenced by prescribed and applied loads stretching. load is calculated from the duration intensity, whereas assessed force exerted on targeted muscle. No previous study has investigated muscle-tendon unit stiffness simultaneously. Therefore, purpose present was to examine acute change in hamstrings using different intensities durations Twenty-three participants underwent at intensity high (50 seconds, 3 sets), moderate (60 low (75 random order....

The asexual ectomycorrhizal fungus Cenococcum geophilum has a wide geographic range in diverse forest ecosystems. Although its genetic diversity been documented at stand or regional scale, knowledge of spatial structure is limited. We studied the and C. eight Japanese coastal pine forests with maximum 1364 km. A total 225 samples were subjected to phylogenetic analysis based on glyceraldehyde 3-phosphate dehydrogenase gene (GAPDH) followed by microsatellite five loci. GAPDH resolved three...
