Background: Instrument Assisted Soft Tissue Mobilization (IASTM) and electrotherapy have shown to help alleviating post-operation complications and affect gait kinematics and muscle strength.Aim: This case study aimed to manage the post-operative complications in a patient with investigate excessive ankle stiffness with kinetics, kinematics and Electromyography (EMG) approach.Materials and Methods: A 41-year-old female with post-operation complications including decreased right ankle range of motion (ROM) and strength underwent a 12-week of IASTM and Electrotherapy. Gait analysis was performed before and after the intervention.Results: The results showed notable improvements in ankle 3-dimensional (3D) ROM, power, moment, velocity, cadence, step length, ground reaction force (GRF) and decreased stiffness, muscles activity, single and double support time. Ankle dorsiflexion ROM was not notably increased during gait.Conclusion: Findings suggest that a 12-week intervention of IASTM and electrotherapy can improve gait mechanics and reduce muscle activity in a patient with excessive ankle stiffness.

Background: The physical fitness is essential for wrestlers to perform successfully. The Tabata Protocol can be appropriate to develop these physical qualities.Aim: This study aims to investigate the effects of high-intensity interval training using “Tabata  protocol” on the physical fitness of teenage wrestlers.Material and Methods: 16 participants were randomly assigned to two groups of Tabata training (n=8) and the control group (n=8). All mentioned variables were measured before and after 4 weeks of the intervention. Tabata training group performed Tabata protocol in 2- 3 sets of 8 exercises with 20 sec of training and 10 sec of rest. The control group kept up their normal training routine during the same time. Physical fitness components were measured. The collected data were statistically analyzed by an independent t-test at a significance level of P>0.05.Results: Wrestlers in both groups significantly increased physical fitness components except flexibility (P<0.05). Tabata training was significantly more efficient in endurance of core muscle (P= 0.019, ES= 0.490) and upper body strength (P= 0.001, ES= 0.490) than control group (P<0.05). Also, results showed that for leg explosive power, only Tabata training had a positive effect (P= 0.026, ES=0.541).Conclusions: Our results suggest that wrestlers after Tabata protocol interventions can obtain better physical fitness, and event time benefits with more efficient performance and time-efficient manner compared with control group.

This study examines whether the geographic distribution of lacrosse talent, as indicated by NCAA Division I All-American awards, has shifted from traditional hotbed states Maryland and New York to other regions over the past 25 years. Data on NCAA Division I All-American lacrosse players from 2000 to 2024 were collected and divided into five periods: 2000-2004, 2005-2009, 2010-2014, 2015-2019, and 2020-2024. The number and percentage of award winners from each state were calculated, and the number of states represented each year was tracked. This was compared with the growth in high school lacrosse participation. Maryland and New York's dominance decreased from 75.0% of All-American winners in 2000-2004 to 39.1% in 2020-2024. Concurrently, high school lacrosse participation grew from 46,206 in 2002-2003 to 107,865 in 2021-2022. The number of states represented increased from 8 in 2002 to 16 in 2024, indicating broader talent distribution. The decreased dominance of Maryland and New York suggests a diversification of lacrosse talent, aligning with nationwide participation growth and more states producing All-American players. This diversification highlights the successful expansion of the sport, ensuring a more inclusive talent pool and reflecting the positive impact of increased access to lacrosse across the country. Lacrosse development programs and recruitment strategies should expand beyond traditional hotbeds to support emerging regions, fostering a more inclusive and diverse talent pool, and enhancing the sport's growth at all levels.

Background: Diabetic peripheral neuropathy (DPN) reduces the senses, proprioception, reflexes, and strength in the lower extremities and leads to balance dysfunction. Aim : This study aimed to evaluate the effectiveness of interventions used by researchers and therapists to minimize balance dysfunction in people with DPN. Materials and Methods: This study is a comprehensive review of exercise interventions on the balance of patients with diabetic neuropathy by searching in the PubMed Elsevier, Springer, Science Direct, Google Scholar, and Scopus databases with the combined keywords “balance”, “diabetic peripheral neuropathy”, “training interventions”, “proprioception”, “risk of diabetic fall”, “peripheral neuropathy” and also in Persian databases of Jihad Daneshgahi Scientific Information Center, MedLib (Comprehensive Database of Medical Articles), IranMedex, Iran Institute of Information Science and Technology Research Institute (IRANDOC), Iranian Publications Database (MAGIRAN) and with keywords “fall risk”, “profundity” and “postural control in diabetic neuropathic patients” from 2010 to 2021. After collecting the search results, first the title and then the summary of the pieces were studied. If the articles met the inclusion and exclusion criteria, their results would be used in the review study and otherwise discarded. Results: Twenty-five studies published between 2010 and 2021 met the inclusion criteria. The results showed that training interventions were more effective than control conditions to improve the balance of patients with diabetic neuropathy. Also, the most training programs and rehabilitation protocols have a positive effect on the balance of patients with diabetic neuropathy. Conclusion: The studied exercise interventions are an effective tool to improve the balance of diabetic neuropathy patients. However, given the small number of studies and their limitations, the present findings of this study should be considered.
