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.

本研究旨在确定步行运动是否能调节坐骨神经损伤（SNI）后同侧腰4至6背根神经节神经元的神经病理性疼痛和炎症反应标志物的表达水平。实验鼠被随机分为七组：正常对照组，损伤后 3、7 和 14 天（dpi）静坐组，以及损伤后 3、7 和 14 天（dpi）步行锻炼组。采用 Western 印迹技术评估特定的神经病理性疼痛和细胞因子标记物，并通过爪退缩试验确认机械异感。与久坐组相比，步行锻炼组在7、10和14 dpi的机械异感都有明显改善。此外，与久坐组相比，步行锻炼组的生长相关蛋白43和脑源性神经营养因子水平在3、7和14 dpi均有明显提高。相反，与久坐组相比，步行锻炼组的活化B细胞核因子卡巴轻链增强因子、白细胞介素-6、肿瘤坏死因子α、降钙素基因相关肽和c-Fos表达水平在3、7和14 dpi均明显下降。这些发现提供了有意义的信息，即在自发性神经损伤后早期进行积极的康复步行锻炼可能会改善自发性神经损伤后的机械异感、神经病理性疼痛和炎症反应指标。

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.

多柔比星（DOX）是一种广泛用于治疗各种癌症的化疗药物，众所周知它会诱发认知障碍。本研究旨在探讨跑步机运动对化疗引起的记忆损伤的影响。我们评估了DOX是否会影响炎症、线粒体Ca2+潴留能力和Wnt/β-catenin信号转导。雄性Sprague-Dawley大鼠被分为对照组、运动组、DOX注射组和DOX注射及运动组。为了建立DOX诱导的记忆损伤模型，大鼠腹腔注射溶于生理盐水的DOX（2 mg/kg），每周一次，连续注射4周。每天进行一次跑步机运动，每周 5 天，连续 8 周。短期记忆采用降阶回避测试进行测定。对海马中的促炎细胞因子、Wnt/β-catenin 信号传导、脑源性神经营养因子（BDNF）、肌球蛋白受体激酶 B（TrkB）进行了 Western 印迹检测。此外，还测量了海马线粒体钙离子潴留能力。DOX注射大鼠的短期记忆力下降，海马中BDNF和TrkB的表达量也随之减少。DOX注射大鼠体内促炎细胞因子肿瘤坏死因子-α和白细胞介素-6的水平升高。注射 DOX 的大鼠体内 Wnt/β-catenin 信号被激活，线粒体 Ca2+ 的潴留能力下降。然而，跑步机运动缓解了短期记忆损伤，减少了促炎细胞因子，增加了BDNF和TrkB的表达，并增强了线粒体Ca2+潴留能力。跑步机运动恢复了Wnt/β-catenin信号通路。这项研究表明，跑步机运动可用于接受DOX化疗的患者。

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.

本研究以精英健美运动员为对象，采用两种减肥方法（传统方法=高体重减轻与新方法=低体重减轻），为期 6 周。本研究的受试者是 26 名自愿参加本实验的男性精英健美运动员，他们被分为实验组和传统组。传统组和实验组都接受了为期 6 周的饮食限制和训练。研究结果得出的结论是，在人体测量变量方面，两组的体重等级存在差异。实验组的上臂围在测量后与测量前的数值相比保持不变，而传统组则有所下降，并且观察到了显著的交互效应。特别是，观察到了明显的交互效应。在最大摄氧量的绝对值方面，只有实验后组与测试前相比有明显增加，而且观察到了交互效应，这说明使用低体重减轻法比传统的高体重减轻法更有效。尽管采用了传统的减重方法，但观察到某些细胞因子有所增加，但并未导致免疫力过度下降或表现因子急剧下降。实验结果表明，与传统的高减重法相比，低减重法在性能变量方面更有优势。

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.

加速度计测量中的时间是影响体力活动（PA）分析结果的一个重要选项。已有许多研究调查了时程对青少年体力活动输出的影响，但很少有研究针对高度活跃的青少年运动员。我们的目的是通过对青少年运动员采用不同的历时长度来研究能量消耗和不同活动强度下所花费时间的差异。这项研究的参与者包括篮球队、足球队和跆拳道队的 31 名 12 至 13 岁的男性运动员。运动员连续 6 到 7 天（包括睡眠时间）在右臀部佩戴三轴加速度计。随后，使用 ActiLife 软件下载加速度计记录的数据，并通过改变 1 秒、10 秒、30 秒和 60 秒的时间间隔进行分析。每日平均代谢当量（METs）随着时间长度的增加而增加（F= 2.918，P= 0.037），显示出 1 秒和 60 秒时间长度之间的显著差异。随着时程的增加，久坐（0-1.5 METs）（F= 94.001，P= 0.000）和高强度（6 METs 及以上）活动时间（F= 3.536，P= 0.017）减少，而低强度（1.5-3METs）（F= 173.949，P= 0.000）、中等强度（3-6METs）（F= 70.792，P= 0.000）和中等至剧烈活动（3METs 及以上强度）（F= 34.683，P= 0.000）时间增加。通过不同加速度计的时间设置对青少年运动员的活动量进行比较，发现了不同活动强度的活动量水平和所花费的时间存在差异。未来的研究应考虑非常活跃的青少年运动员的PA输出随时间长短的特征变化。

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.

发育迟缓的范围很广，根据肌肉张力的不同，会出现不同的运动特征。我们旨在研究不同肌张力的发育迟缓（DD）儿童在坐立时的肌肉活动和加速度。我们将 40 名参与者分为三组：典型发育（TD）儿童（18 人）、肌张力过高发育迟缓儿童（12 人）和肌张力过低发育迟缓儿童（10 人）。肌电图用于测量肌肉活动，BTS G-Walk 用于测量加速度。结果显示，腹直肌和股四头肌的活动量在患有肌张力过高症的发育迟缓儿童中低于患有肌张力过低症的儿童（P< 0.05）。肌张力过低的聋哑儿童的胫骨前肌活动量高于智力发育迟缓的儿童（P< 0.05）。肌张力过低的残疾儿童的躯干角度大于患有肌张力过高的残疾儿童（P< 0.05），垂直加速度低于患有肌张力过高的残疾儿童（P< 0.05）。根据这些差异，我们将能够针对不同肌张力的 DD 儿童的特点提供合适的干预方案。

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。

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.","PeriodicalId":15771,"journal":{"name":"Journal of Exercise Rehabilitation","volume":"25 45","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139156176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

本研究旨在验证音乐锻炼计划对乐器演奏者姿势平衡和情绪因素的影响。我们招募了 11 名年龄在 25-45 岁之间的器乐演奏家，要求他们进行为期 8 周、每周三次、每次 60 分钟的音乐练习。我们使用身体姿势分析仪测定了参与者的前平衡和横向排列。为了评估情绪因素，研究人员使用了世界卫生组织生活质量量表、压力反应量表和罗森伯格自尊量表。这项研究没有发现前姿失衡和侧姿不齐在统计学上有显著差异。相反，包括生活质量、压力反应和自尊分项在内的情绪因素则表现出显著差异。本研究中以音乐为基础的锻炼计划明显改善了情绪因素。然而，要确保器乐演奏者的姿势失衡问题得到改善，还需要制定更有条理的长期计划。

This study aimed to investigate the effect of a 12-week accelerated rehabilitation exercise program on isokinetic strength and dynamic balance ability of thighs in 20 adult men who underwent anterior cruciate ligament reconstruction (ACLR) or posterior cruciate ligament reconstruction (PCLR) and to analyze intergroup differences in recovery patterns. In this study, we examined 10 patients who underwent ACLR and 10 who underwent PCLR. These patients participated in an accelerated rehabilitation exercise program 5 times weekly for 12 weeks. The participants' isokinetic strength, muscular endurance, and dynamic balance ability of the femoral muscles were measured before and 12 weeks after reconstruction surgery. Isokinetic knee muscle function showed no significant difference between the ACLR and PCLR groups at 60°/sec. Both the groups demonstrated significant increases in muscle strength between the flexors and extensors. However, a between-group difference was noted in knee muscular endurance at 180°/sec, with ACLR patients showing significant differences between extensors and flexors, unlike PCLR patients. Assessment of the dynamic balance ability revealed that overall knee stability did not significantly differ between groups, and both the ACLR and PCLR groups exhibited improved dynamic balance ability. However, significant differences were found in anteroposterior and left-right stabilities. Patients who underwent ACLR had significantly improved anteroposterior and left-right stability, wherever patients who underwent PCLR showed no significant difference. This accelerated rehabilitation exercise program improved the muscle strength and muscular endurance of patients who underwent ACLR and PCLR, suggesting its potential efficacy in recovering dynamic balance ability, particularly after ACLR.

本研究旨在研究为期12周的加速康复锻炼计划对20名接受前交叉韧带重建（ACLR）或后交叉韧带重建的成年男性大腿等速力量和动态平衡能力的影响，并分析恢复模式的组间差异。在这项研究中，我们检查了10名接受ACLR的患者和10名接受PCLR的患者。这些患者参加了加速康复锻炼计划，每周5次，为期12周。在重建手术前和手术后12周，测量参与者的等速力量、肌肉耐力和股肌肉的动态平衡能力。在60°/秒时，ACLR组和PCLR组的等速膝关节肌肉功能没有显著差异。两组的屈肌和伸肌之间的肌肉力量都显著增加。然而，在180°/秒的膝关节肌肉耐力方面，组间存在差异，与PCLR患者不同，ACLR患者的伸肌和屈肌之间存在显著差异。对动态平衡能力的评估显示，各组之间的整体膝盖稳定性没有显著差异，ACLR和PCLR组都表现出改善的动态平衡能力。然而，前后稳定性和左右稳定性存在显著差异。接受ACLR的患者前后和左右稳定性显著改善，而接受PCLR的患者则没有显著差异。这种加速康复锻炼计划提高了接受ACLR和PCLR的患者的肌肉力量和肌肉耐力，表明其在恢复动态平衡能力方面的潜在疗效，特别是在ACLR之后。
