Six-min walk test (6MWT) is widely used exercise test for the evaluation of interstitial lung disease (ILD). However, the long test duration and need for long and flat surface hinder its routine use. One-min sit-to-stand test (1-STST) is devoid of such limitations, but has been scarcely evaluated. The study was conducted to evaluate the performance of 1-STST by correlating it with 6MWT in ILD patients. Stable ILD patients were prospectively enrolled. After initial spirometry, all patients performed 6MWT and 1-STST following the standard recommendations. Exercise capacity and physiological parameters (heart rate, pulse oxygen saturation, blood pressure and dyspnea [modified Borg scale]) including peripheral oxygen saturation (SpO2) were correlated after the tests using Pearson correlation, Intraclass correlation coefficient (ICC) and kappa (κ) coefficient. The results showed that the mean age of the patients (n= 60) was 58.8± 11.5 years (male:female= 1:1). Repetitions after 1-STST showed significant correlation with 6MWT (r = 0.48; P< 0.001). Changes in the physiological variables were similar (P> 0.05) with good consistency (ICC= 0.68–0.95) between 6MWT and 1-STST. Both lowest SpO2 and difference in SpO2 also showed good agreement (ICC= 0.86; 95% confidence interval [CI], 0.77–0.92 and ICC= 0.68; 95% CI, 0.47–0.81 respectively) and significant correlation (r = 0.76 and r= 0.52, respectively). 1-STST and 6MWT were consistent in identifying patients having oxygen desaturation ≥ 4% (κ= 0.56; 96% CI, 0.30–0.82). The results demonstrated that the performance of 1-STST was consistent with 6MWT in terms of exercise capacity and change in physiological parameters. 1-STST can be a valid alternative to 6MWT in the assessment of ILD patients, especially in peripheral health centers.

The aim of this study was to determine whether walking exercise can regulate the expression level of neuropathic pain- and inflammatory response markers in the ipsilateral lumbar 4 to 6 dorsal root ganglion neurons after sciatic nerve injury (SNI). The experimental rats were randomly divided into seven groups: the normal control group, sedentary groups for 3, 7, and, 14 days postinjury (dpi), and walking exercise groups for 3, 7, and 14 dpi. Western blot techniques were used to evaluate specific neuropathic pain- and cytokine markers and mechanical allodynia was confirmed by paw withdrawal test. Mechanical allodynia was significantly improved in the walking exercise group compared to the sedentary group at all 7, 10, and 14 dpi. Furthermore, growth associated protein 43 and brain-derived neurotrophic factor levels were significantly increased in the walking exercise groups compared to the sedentary group at all 3, 7, and 14 dpi. Conversely, nuclear factor kappa-lightchain-enhancer of activated B cells, interleukin-6, tumor necrosis factor α, calcitonin gene-related peptide, and c-Fos expression levels were significantly decreased in the walking exercise groups compared to the sedentary group at all 3, 7, and 14 dpi. These findings suggest meaningful information that aggressive rehabilitation walking exercise applied early after SNI might be improve mechanical allodynia, neuropathic pain and inflammatory response markers following SNI.

This study was conducted on elite bodybuilders for 6 weeks using two weight loss methods (traditional method = high-weight loss vs. new method= low-weight loss). The subjects of this study were 26 male active elite bodybuilders who voluntarily wanted to participate in this experiment, and were divided into experimental group and traditional group. The traditional and experimental groups underwent dietary restrictions and training for 6 weeks. The conclusion obtained from the results of this study is that in the case of anthropometric variables, there is a difference in weight class between the two groups. The experimental group’s upper arm circumference was maintained compared to the pre-measured value after post-measurement, while the traditional group decreased, and a significant interaction effect was observed. In particular, a significant interaction effect was observed. In that the absolute value of maximum oxygen intake was significantly increased only in the post-experimental group compared to the pretest, and an interaction effect was observed, the use of low-weight loss method is more effective than the traditional method of high-weight loss method. An increase in some cytokines was observed despite traditional weight loss, but it did not cause an excessive decrease in immunity or a sharp decrease in performance factors. As a result of this experiment, it is judged that the use of a low-weight loss method is more preferable than the traditional high-weight loss method in relation to performance variables.

Doxorubicin (DOX) is a widely used chemotherapy drug for various cancers and it is known to induce cognitive impairment. The aim of this study was to investigate the effect of treadmill exercise on chemotherapy-induced memory impairment. We assessed whether DOX affects inflammation, mitochondrial Ca2+ retention capacity, and Wnt/β-catenin signaling. Male Sprague-Dawley rats were divided into control group, exercise group, DOX-injection group, and DOX-injection and exercise group. To create a DOX-induced memory impairment model, animals were injected intraperitoneally with DOX (2 mg/kg) dissolved in saline solution once a week for 4 weeks. Treadmill exercise was performed once a day, 5 days a week, for 8 consecutive weeks. Short-term memory was determined using the step-down avoidance test. Western blot was performed for the proinflammatory cytokines, Wnt/β-catenin signaling, brain-derived neurotrophic factor (BDNF), tropomyosin receptor kinase B (TrkB) in the hippocampus. Mitochondrial Ca2+ retention capacity in the hippocampus was also measured. DOX-injection rats showed deterioration of short-term memory along with decreased expression of BDNF and TrkB in the hippocampus. Levels of the proinflammatory cytokines, tumor necrosis factor-α and interleukin-6, were increased in the DOX-injection rats. Wnt/β-catenin signaling was activated and mitochondrial Ca2+ retention capacity was decreased in the DOX-injection rats. However, treadmill exercise alleviated short-term memory impairment, decreased proinflammatory cytokines, increased BDNF and TrkB expression, and enhanced mitochondrial Ca2+ retention capacity. Treadmill exercise restorated Wnt/β-catenin signaling pathway. This study demonstrated that treadmill exercise can be used for patients undergoing chemotherapy with DOX.

Epoch in accelerometer measurements is an important option that affects the results of physical activity (PA) analysis. Many studies have been conducted to investigate the effect of epoch on PA output in adolescents, but few have been performed on highly active youth athletes. We aimed to examine the differences in energy expenditure and time spent in different activity intensities by applying various epoch lengths in adolescent athletes. The participants of this study comprised 31 male athletes aged 12 to 13 in basketball, soccer, and taekwondo teams. Athletes wore a tri-axial accelerometer attached to the right hip for 6 to 7 consecutive days, including sleeping time. Subsequently, the recorded data from the accelerometer were downloaded using the ActiLife software and analyzed by varying the epoch to 1, 10, 30, and 60 sec. Daily average metabolic equivalents (METs) increased as the epoch increased (F= 2.918, P= 0.037), showing a significant difference between 1 and 60-sec epochs. As epoch length increased, sedentary (0–1.5 METs) (F= 94.001, P= 0.000) and high intensity (6 METs and higher) activity time (F= 3.536, P= 0.017) decreased, while low (1.5–3 METs) (F= 173.949, P= 0.000), moderate (3–6 METs) (F= 70.792, P= 0.000), and moderate-to-vigorous activity (3 METs and higher intensity) (F= 34.683, P= 0.000) times increased. Comparing PA among adolescent athletes by varying epoch settings of accelerometers revealed differences in PA levels and time spent in different activity intensities. Future studies should consider the characteristic changes in the PA outputs according to the epoch length in very active adolescent athletes.

Developmental delays cover a wide range, with different movement characteristics occurring depending on differences in muscle tone. We aimed to investigate muscle activity and acceleration during sit-tostand in developmentally delayed (DD) children with different muscle tones. Forty participants were divided into three groups: typically developing (TD) children (n= 18), DD children with hypertonia (n= 12), and DD children with hypotonia (n= 10). Electromyography was used to measure muscle activity and BTS G-Walk was used to measure acceleration. As a result, the activities of the rectus abdominal muscle and quadriceps muscle were lower in DD children with hypertonia than in TD children (P< 0.05). The activity of the tibialis anterior muscle was higher in DD children with hypotonia than in TD children (P< 0.05). The trunk angle was greater in DD children with hypotonia than in TD children (P< 0.05), and vertical acceleration was lower in DD children with hypertonia than in TD children (P< 0.05). Based on these differences, we will be able to provide intervention programs appropriate for the characteristics of DD children with different muscle tone.

The objective of this study was to assess the effect of two different strength-training methods on both male and female water polo players’ performance and shoulder pain. The players were randomly allocated to a maximum strength (MS: 14 males, 8 females) or power strength (PS: 13 males, 8 females) training group. Before and after the intervention, we assessed player´s anthropometric characteristics, shoulder internal and external rotation strength, hand grip strength, upper body strength, countermovement jump height, throwing velocity, swimming speed, shoulder pain on a visual analogue scale (VAS), wellness, and rate of perceived exertion per session. We observed no significant improvement (P< 0.05) in specific skills but enhancement in hand grip strength in male players. In female players in the MS group, throwing speed and bench press weight decreased significantly (P< 0.05). Shoulder external rotation strength at 240°/sec in male MS group players and shoulder external rotation strength at 60°/sec in female PS group players decreased significantly (P< 0.05). In addition, from the first to the last week, shoulder pain increased significantly (P< 0.05) in all players. Inverse correlations (P< 0.05) were found between VAS and shoulder rotation strength in males in the PS group, and between wellness and shoulder internal rotation strength in men in the MS group and women in the PS group. We found that both MS and PS training did not enhance performance and increased shoulder pain in male and female water polo players.
本研究旨在评估两种不同的力量训练方法对男女水球运动员成绩和肩痛的影响。球员被随机分配到最大力量（MS：14 名男性，8 名女性）或力量（PS：13 名男性，8 名女性）训练组。在干预前后，我们评估了球员的人体测量特征、肩部内旋和外旋力量、手部握力、上肢力量、反运动跳跃高度、投掷速度、游泳速度、视觉类比量表（VAS）显示的肩部疼痛、健康状况以及每次训练的感知消耗率。我们观察到，男性运动员在特定技能方面没有明显改善（P< 0.05），但手部握力有所增强。在 MS 组的女运动员中，投掷速度和卧推重量明显下降（P< 0.05）。MS组男队员在240°/秒时的肩关节外旋力量和PS组女队员在60°/秒时的肩关节外旋力量都明显下降（P< 0.05）。此外，从第一周到最后一周，所有球员的肩痛都明显增加（P< 0.05）。在 PS 组男性球员的 VAS 与肩关节旋转力量之间，以及在 MS 组男性球员和 PS 组女性球员的健康状况与肩关节内旋力量之间发现了反相关性（P< 0.05）。我们发现，MS 和 PS 训练都不能提高男女水球运动员的成绩，反而会增加他们的肩部疼痛。

Plank is a readily accessible form of exercise that can benefit individuals of various fitness levels. However, its effectiveness in older individuals has not been conclusively established. Specifically, its impact on respiratory function, physical fitness, and immunocytes in them has not been thoroughly verified. The study encompassed participants with an average age of 64.33± 1.98 years. All participants were randomly assigned to either the control group (COG) or the plank exercise group (PXG). The plank exercise was conducted 3 days a week for 12 weeks. While the values in the COG deteriorated, the PXG showed significant improvements in several parameters. Forced expiratory volume in one second and peak expiratory flow increased by approximately 27% and 16%, respectively, in the PXG, demonstrating significant differences (P< 0.001) between the two groups. Additionally, VO2max, grip strength, and sit-ups increased by about 12%, 18%, and 42% in the PXG. Notably, innate immunocytes, such as NK cells, increased by approximately 30% in the PXG. For adaptive immunocytes, including CD3+ T cells, CD4+ T cells, and CD8+ T cells, there were notable increases of around 18%, 19%, and 28%, respectively, in the PXG. These findings underline significant differences (P< 0.001) between the two groups. This study provides confirmation that engaging in plank exercise can enhance the function of immunocytes, while also improving respiratory capacity and physical fitness in older adults.
平板支撑是一种易于接受的锻炼方式，对不同体能水平的人都有益处。然而，它对老年人的有效性尚未得到证实。具体来说，它对老年人呼吸功能、体能和免疫细胞的影响尚未得到彻底验证。这项研究的参与者平均年龄为 64.33±1.98 岁。所有参与者被随机分配到对照组（COG）或平板运动组（PXG）。平板运动每周进行 3 天，为期 12 周。虽然 COG 组的数值有所下降，但 PXG 组的几项参数却有明显改善。PXG 组的一秒用力呼气量和呼气峰值流量分别增加了约 27% 和 16%，两组之间差异显著（P< 0.001）。此外，PXG 组的最大氧饱和度、握力和仰卧起坐分别增加了约 12%、18% 和 42%。值得注意的是，先天性免疫细胞（如 NK 细胞）在 PXG 中增加了约 30%。至于适应性免疫细胞，包括 CD3+ T 细胞、CD4+ T 细胞和 CD8+ T 细胞，在 PXG 中分别显著增加了约 18%、19% 和 28%。这些发现强调了两组之间的显著差异（P< 0.001）。这项研究证实，进行平板运动可以增强免疫细胞的功能，同时还能提高老年人的呼吸能力和体能。

This study aimed to verify the effects of a music-based exercise program on postural balance and emotional factors among instrumentalists. We recruited 11 instrumentalists aged 25–45 years who were asked to perform a music-based exercise program for 60 min per session, three sessions weekly, for 8 weeks. The anterior balance and lateral alignment of the participants were determined using a body posture analyzer. To assess the emotional factors, the World Health Organization Quality of Life, stress response inventory, and Rosenberg self-esteem scale were used. This study did not reveal a statistically significant difference in anterior postural imbalance and lateral misalignment. In contrast, emotional factors, including quality of life, stress response, and the self-esteem subcategories, exhibited significant differences. The music-based exercise program in this study significantly improved the emotional factors. Nevertheless, a more structured and long-term program should be developed to ensure the improvement of postural imbalance among instrumentalists.
