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...

Foam rolling (FR) and vibration foam (VFR) interventions have received attention as pre-exercise warm-ups because they maintain performance increase range of motion (ROM). However, the immediate prolonged effects comparisons between FR VFR are unknown. Therefore, this study was designed to compare on passive properties knee extensors over time (up 30 min after interventions). A crossover, random allocation design used with 14 male college students (22.1 ± 1.0 years old) in control, FR,...
It is well-known that unusual exercise, especially eccentric contraction (ECC), could cause delayed-onset muscle soreness. However, the factors related to loss of strength and range motion (ROM) caused by eccentrically damaged muscle, such as increases in soreness, tissue hardness, pain threshold, have not been investigated detail. Thus, this study was conducted investigate ROM a large sample. Fifty-six sedentary healthy young male volunteers were instructed perform 60 repetitions ECC...
Previous research has shown that vibration foam rolling (VFR) on damaged muscle shows greater improvement in soreness and range of motion (ROM) compared with (FR) without vibration. However, the effect frequency VFR loss function caused by muscles is unknown.

Static stretching (SS) and dynamic (DS) in combination with foam rolling (FR) have been attracting attention as warm-up routines sports. However, the combined intervention order effects of SS or DS FR on flexibility, muscle strength, jump performance are still unclear. Therefore, this study aimed to compare various orders (i.e., + FR, SS, FR) function properties knee extensors. Using a crossover, random allocation design, 17 male university students (21.0 ± 1.1 y) performed four conditions...

Here, we investigate effect environment composition during post-exposure delay (PED) on metal oxide resists (MOR). We applied specific environments a fixed PED time and measured each condition printed L/S patterns by measuring change final critical dimension (CD) case compared reference control. performed chemical analysis elucidate which changes take place resist under...
ABSTRACT Our previous study showed that daily six maximal eccentric contractions were performed 5 days a week for 4 weeks increased voluntary isometric (MVC‐ISO), concentric (MVC‐CON), and contraction (MVC‐ECC) strength of the elbow flexors muscle thickness biceps brachii brachialis (MT) by 8.3 ± 4.9%, 11.1 7.4%, 13.5 11.5%, 10.6 5.1%, respectively. In present study, we tested hypothesis MT would still increase when training intensity was reduced to 2/3 or 1/3 peak MVC‐ECC torque. Thirty‐six...

J Strength Cond Res 38(11): 1879-1884, 2024-A (RM) is type foam rolling device, which previous studies have shown to be effective for acutely decreasing tissue hardness increasing range motion (ROM). However, these may differ with RM position (i.e., knee flexion or extension). Therefore, this study aimed compare acute...
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...
Algometers are commonly used to measure the pain-pressure threshold (PPT) in various tissues, such as muscle, tendons, or fascia. However, date, it is not clear if repeated application of a PPT assessment can adjust pain thresholds muscles. Therefore, purpose this study was investigate tests (20 times) elbow flexor, knee extensor, and ankle plantar flexor muscles both sexes. In total, 30 volunteers (15 females, 15 males) were tested for their using an algometer on respective random order. We...
