Being a contact sports in nature, soccer players are susceptible to various kinds of injuries such as lower extremities muscle injury. In addition to those familiar injuries that soccer players sustain during the game, traumatic brain injury is also a possibility. Head impacts in soccer could be a result of head-to-head impact with an opponent player, head-to-elbow impact, an impact with the goal post, impact with the ground, as well as an impact with the soccer ball, which occurs during a heading manoeuvre. Soccer allows the players to use their head to hit the ball to pass it to a teammate, or even perform heading to score goal. Although soccer heading is perceived as less harmful as compared to head impacts with other hard objects, many studies have shown compelling evidence that this repetitive heading might harm the brain, thereby leading to traumatic brain injury. Protective headgears designed, especially for soccer players have been commercially available in the market for some years. Objective: This article investigates the effectiveness of two padding foams by means of heading experiment. Methodology: An anthropometric test device known as Hybrid III head and neck dummy instrumented with an inertial sensor that consists of a triaxial accelerometer and gyroscope installed at the centre of gravity of the head was used in the experiment. A soccer ball launching machine was used to propel the ball at several inbound velocities. Peak linear acceleration and peak rotational acceleration (PRA) were recorded, and the head injury criterion (HIC) and the rotational injury criterion (RIC) were calculated. Results: Poron X-ray diffraction (XRD) foam was found to provide the best protection in both linear and rotational components. However, for protection against HIC, it is evident from the findings that both foams were very effective at lower inbound ball velocity and became drastically ineffective as the inbound velocity increases up to 22 m/s (i.e. equal to 79.2 km/h). This could be attributed to the foam being completely compressed by the high-velocity ball impacting it. The same situation is seen for RIC, however with less significant decline in protective performance. Conclusion: Overall, it can be concluded that the Poron XRD foam could be a better foam to be used in soccer headgear as compared to the yoga mat foam.","PeriodicalId":415126,"journal":{"name":"Malaysian Journal of Movement, Health & Exercise","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128781335","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}

However, an injury profile of elite soccer players in Malaysia is yet to be determined. Aim and Objectives: This study was conducted to determine the injury characteristics among elite, male U19 and U22 soccer players. Materials and Methods: Four teams were observed throughout the 2018/2019 season, where a total of 111 players were documented in accordance with the Federation International de Football Association Medical and Research Centre accord to determine the incidence, class, severity and causation of injuries among elite, male U19 and U22 soccer players. Results: From a total of 111 players (U19: n = 58; U22: n = 53) during the 2018–2019 season, a sum of 64 injuries were reported to the team physicians of the participating teams in the current study, representing an estimated 0.58 injuries per player throughout a single season. From the total number of injuries, 57.8% (n = 37) injuries were registered to the U22 age group, whereas 42.2% (n = 27) were reported in the U19 Age Group. When factoring in the number of players in each respective age group, the number of injuries among the U22 age group was higher than the U19 age group (0.72 vs. 0.47 injuries/player/season). Conclusion: Most soccer injuries reported were lower limb injuries, newly sustained and required up to 14 days of treatment before returning to full participation in the competition. Match-play injuries appeared to be more common than training injuries, with the ankle and knee joints being the most common injury locations. Sprains and ligamentous damage were the most common injury class sustained by players.","PeriodicalId":415126,"journal":{"name":"Malaysian Journal of Movement, Health & Exercise","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121881039","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}

Aim and Objectives: This was a retrospective study to describe the injuries and illnesses seen during Four Feather Ultra Marathon 2020, Sabah, held from 29th February 2020 to 1st March 2020, for future preparation of medical team standby. Methods: All ultramarathoners who reported to the medical camp or on site with medical complains, and musculoskeletal complains were included in the study pools. There were 6 medical camp sites; KM10, KM19, KM36, KM51, KM62 and KM90. Results: The incidence of injury was 504 per 1000 athletes, 478 per 1000 km run, and 401.4 per 1000 h run. There was no severe injury or medical illness that require urgent referral to a hospital. For minor injuries and illnesses, 54.3 % due to medical conditions, 39.8% due to musculoskeletal injuries and 5.9% due to skin conditions. For heat-related illness, 31.5% were heat cramps and 15.7% were heat exhaustion. 50KM category runners have the highest percentage of heat-related illness (78.3%) followed by 90km category (11.7%) and 20km category (10%). 74.2% (n = 89) of heat-related illness occurred at KM 19, 20% (n=24) occurred at KM 37, 2.5% (n = 3) at KM 50, and 3.3% (n = 4) at KM 70.

Aims: The aim of this preliminary study was to investigate whether the modified treadmill versus overground soccer-specific simulation replicated the physiological effects of match-play. Methods: Six healthy (n = 6) recreationally soccer-trained male players (age, 24 ± 2 years; height, 173 ± 7 cm and body mass, 76 ± 6 kg) participated in this repeated measure design study. During the testing session, each player completed a 45-min treadmill and overground-simulated match-play involving the same average running velocity. Heart rate and rating of perceived exertion (RPE) were recorded every 5 min throughout the simulation. Results: The physiological responses in the overground simulation (heart rate 169 ± 9 beats.min−1; RPE 14 ± 1) were significantly greater than the treadmill simulation (heart rate 145 ± 12 beats.min−1; RPE 12 ± 1). Conclusions: The heart rate and RPE response in the overground simulation was consistent with soccer players during actual match-play. The treadmill simulation, however, demonstrated a lesser physiological response compared to that as observed during match-play likely due to the exclusion of utility movements and high accelerations and deceleration.","PeriodicalId":415126,"journal":{"name":"Malaysian Journal of Movement, Health & Exercise","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125288483","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}

However, the outcome depends more on the individual's re-learning process. Identification of this lacuna and focussed attention to the isometric strength of quadriceps are lacking in the current practice, and developing a tool can lead to optimal outcomes in ACLR. The objective of this study was to assess the role of 'isometric quadriceps pressure difference' (IQPD) in regaining quadriceps strength following the ACLR using a simple tool. Patients and Methods: Eight patients who underwent post-operative ACL rehabilitation between March 2016 and May 2018 were analysed retrospectively. A 'progressive isometric training protocol (PITP)' based on IQPD was prescribed along with the standard protocol. Data were collected from the case records of the patients. IQPD, thigh muscle girth and heel height difference (HHD) were noted pre-operatively, immediately following surgery and 3 months post-operatively. A non-parametric test was used to compare the outcomes before and after surgery. Results: Based on the analysis, the inclusion of IQPD-based PITP in regaining the terminal extension had a significant statistical difference in the IQPD, HHD and girth (p < 0.007, p < 0.005 and p = 0.027, respectively). Conclusion: IQPD can be a simple, cost-effective strategy to identify subtle quadriceps weakness. Further, PITP can improve the isometric quadriceps strength in the acute post-operative period and reduce the incidence of knee extension deficit in post-ACLR.","PeriodicalId":415126,"journal":{"name":"Malaysian Journal of Movement, Health & Exercise","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129044076","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}

This case study explores the variables of swimming performance using the video analysis method. Purpose: To determine the best indicator from a set of swim variables (digitised from video) for competitive swim races by one Malaysian freestyle swimmer in preparation for the Tokyo Olympic Games 2020. Methods: Race video footage was analysed retrospectively to determine the key parameter for each event distance. The following variables were calculated: start time, end time (ET), turn time (TT), stroke count, stroke length, stroke rate, average velocity (AV) and stroke index. Differences were subsequently assessed among the parameters within the same event style. Results: The results from the correlation test between the eight digitised variables and final time (FT) showed that for both 200 and 400 m events the variables AV (respectively, r = −0.96 and r = −0.94) and TT (respectively, r = 0.89 and r = 0.83) were significantly correlated. In addition, for the 200 m events, the ET also significantly correlated (r = −0.94) with FT.

However, Malaysian swimming performance declined during the 2019 SEA Games, intensifying the urgency to identify events that have the highest potential for Malaysian swimmers to achieve a podium finish by comparing international swimming records of previous SEA (SG), Asian (AG) and Commonwealth (CG) games, and also world records with those recorded during the 2021 Malaysia Open which involved swimmers from the Malaysian national team. Methods: Primary data from the Malaysia Open were converted into swim points according to FINA's formula and compared with SG, AG, CG and world records dated up to 25 August 2021 (including records set during the Tokyo Olympics) using a spreadsheet programme. Results: Analyses (n = 80 male and 79 female records) revealed that: (i) Malaysian male swimmers were strongest in the middle-distance freestyle and backstroke events, while female swimmers were best in the short- and middle-distance breaststroke events; (ii) overall Malaysian swimmers' swim points were 30 years behind current world standards; (iii) current male and female national team swimmers have a possibility of undergoing successful participation experience in 30% and 60% of international-level events, respectively and (iv) swimmers from Singapore and Vietnam won most of the medals offered at SG, while China, Japan and South Korea are the main winners at AG.

In this study, we proposed a self-guide assessment to safely return to exercise using post-COVID-19 Physical Activity Readiness Questionnaire and discussed on COVID-19 survivor-graded exercise programme. The key points highlighted during graded exercise programme are (1) individualisation, (2) monitoring for red flag symptoms (chest pain, breathlessness at rest or minimal exertion, palpitation, chest tightness and severe calf pain), (3) step down 1 stage if feels extreme fatigue on exercise, (4) start slow and progress slow with the exercise and (5) if in doubt, to refer yourself out to health professionals. These steps will encourage COVID-19 survivors to continue being active. It will also ease the healthcare burden by reducing the number of referrals of pre-participation health evaluation for mild symptoms or asymptomatic COVID-19 survivor patients to return to exercise.","PeriodicalId":415126,"journal":{"name":"Malaysian Journal of Movement, Health & Exercise","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125105641","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}
