A Case of Fatal Asphyxia by a Barbell during a Bench Press

The bench press is a widespread form of weight training with few scientific reports on its associated fatalities. We herein report a case of an individual performing bench press training who was found deceased in a supine position on the bench with the shaft of the barbell resting on his neck. The bench press safety bars were set at bench height. On the basis of the postmortem computed tomography imaging and the autopsy, the cause of death was determined to be fatal traumatic asphyxia caused by a cervical compression. We wish to highlight the importance of correctly using safety devices during weight training as well as the need for developing and disseminating safe equipment that is not dependent on the manner of use. We also wish to highlight the need for a form of legal regulation on the design of devices.

Effect of body weight training plus low carbohydrate diet versus running plus low carbohydrate diet on body fat percentage changes in overweight and obese young man

This study aims to determine the effect of body weight training combined with a low carbohydrate diet and running combined with a low carbohydrate diet on reducing body fat percentage in overweight and obese young man. The research used pretest posttest group design experimental method. The sample consisted of 30 young man divided into two groups that had been strictly selected. Their body fat percentage was measured before and after the research program. The result was analyzed through paired sample t-test at a significance level of α 0.05 and the average difference test (independent sample t-test posttest) to get a better result. This study shows that body weight training combined with a low carbohydrate diet and running combined with a low carbohydrate diet have a significant effect on decreasing body fat percentage, but running combined with a low carbohydrate diet is better at reducing body fat percentage compared with body weight training combined with a low carbohydrate diet. Overweight and obese young man can apply body weight training combined with a low carbohydrate diet or run combined with a low carbohydrate diet to reduce body fat percentage, but to get the results of a reduction in body fat percentage running and low carbohydrate diets is more recommended.

The effect of skipping combination with body weight training on cardiorespiratory endurance and body mass index (BMI) as a covid-19 prevention effort for overweight adolescents

This study aims to determine the effect of skipping combination with body weight training on cardiorespiratory endurance and BMI as an effort to prevent Covid 19 for overweight adolescents. This research is an experimental research. In this study, treatment was given in the form of skipping exercise combined with body weight training for 8 weeks with a frequency of 3 times / week, an intensity of 60%-70% MHR with a duration of 30 minutes. The population in this study were teenagers. Sampling was done by purposive sampling on adolescents aged between 17-21 years and overweight. Instrument used to measure VO2 max with MFT (multistage fitness test) and measurement of height and weight to determine BMI. The data analysis technique used prerequisite test and paired t test. Based on the results of the cardiorespiratory endurance data analysis, the t-count value was 10.495 with a significance value of 0.000, it can be concluded that there is a significant effect of skipping combination with body weight training on cardiorespiratory endurance in overweight adolescents. The mean value of the cardiorespiratory endurance pretest was 34.92 and the posttest average increased to 40.05. While the results of the analysis on BMI data obtained a t-count value of 15.293 with a significance value of 0.000, it can be concluded that there is a significant effect of skipping combination with body weight training on BMI in overweight adolescents. The mean value of the BMI pretest was 26.60 and the posttest average BMI decreased to 22.19. So it can be concluded that skipping exercises combined with body weight training can increase cardiorespiratory endurance and reduce BMI as an effort to prevent Covid 19 for overweight adolescents.

819Muscle strengthening activities among Australian adults

Focus of Presentation Australian studies examining muscle-strengthening activity (MSA) are limited and most are focused on resistance/weight training. This study uses the nationally representative Sport Australia AusPlay survey of physical activity participation and classifies activities that use major muscle groups as MSAs, adapting the methodology used in UK health studies. Using this classification, estimates are then made on how many Australian adults are doing MSAs on at least two days a week as per the Australian Physical Activity and Sedentary Behaviour Guidelines. Findings There is some uncertainty about which activities can be considered MSAs. However, evidence suggests that many activities, besides resistance/weight training, can strengthen muscles. Three definitions were used to classify physical activities reported by AusPlay respondents as either Resistance Training Only, Definitely MSAs, or Definitely and/or Potentially MSAs. These were applied to AusPlay 2017–18 data to estimate the proportion of adults who met the MSA guideline. For the primary measure of Definitely MSAs, estimates were higher than those from previous Australian studies. Consistent with previous Australian studies, a higher proportion of men than women, and younger adults than older adults, met the MSA guideline across all activity classifications. Conclusions/Implications Survey estimates of MSA participation depend on which activities are included as MSAs. More rigorous studies are needed to clearly categorise which activities can be considered as MSAs. Key messages A clearer understanding of what constitutes MSAs will improve estimates of how many Australian adults are meeting the MSA guidelines.

The Effect of an 8-Week Hamstring Weight Training on H/Q ratio and H/Q FI of Male College Students

PURPOSE: This study aimed to examine the effects on the hamstring/quadriceps ratio (H/Q ratio) and H/Q ratio fatigue index (H/Q FI) of the knee joint of an 8-week weight training to improve the hamstring muscles of male college students.METHODS: Twenty male college students were divided into two groups: an exercise group (EG) and a control group (CG). The EG participated in an 8-week hamstring weight training program, working out twice a week, 60 min per session, with a 60–80% 1RM and 12–16 RPE intensity. The peak torque, H/Q ratio, and H/Q FI were measured, and a t-test was used to verify the statistical significance of the difference between the pre- and post-intervention results.RESULTS: The right flexor peak torque at 60°/sec increased by 14.10±9.60%BW in the EG and decreased by −9.00±16.55%BW in the CG, showing a significant difference between the groups (<i>p</i><0.01). The left flexor peak torque increased by 6.60±12.31%BW in the EG and decreased by −5.10±10.68%BW in the CG, showing a significant difference between the groups (<i>p</i><0.05). The left extensor peak torque decreased by −5.40±19.53%BW in the EG and by −28.40±25.70%BW in the CG, showing a significant difference between the groups (<i>p</i><0.05). The H/Q ratios tended to increase, but the difference was not significant.CONCLUSIONS: To prevent injuries and stabilize the knee joint, the central joint of the lower extremity that plays an important role in daily life and sports activities, hamstring weight training can be performed to maintain the H/Q ratio within the normal range.

INTRODUÇÃO: A autoestima é um aspecto psicológico que reflete em diversas áreas da vida dos indivíduos, inclusive na prática de exercício físico. Na mesma perspectiva, a paixão é uma variável motivacional importante e que corresponde à forma como o indivíduo trata uma atividade, para a qual demanda tempo e energia. OBJETIVO: Analisar a autoestima e paixão em universitários praticantes de musculação. MÉTODOS: Participaram da pesquisa com caráter descritivo transversal, 96 universitários (48 homens e 48 mulheres), com média de idade de 21,90±3,10 anos, praticantes de musculação na academia escola da Universidade Estadual de Maringá - PR. Os instrumentos utilizados foram uma ficha de identificação, Escala de Autoestima de Rosenberg e Escala da Paixão. Para análise dos dados foram utilizados os testes Kolmogorov-Smirnov, U de Mann Whitney e coeficiente de correlação de Spearman, adotando-se p<0,05. RESULTADOS: No geral, os resultados demonstraram que os universitários apresentaram elevada autoestima (Md=32,00), valores superiores para paixão harmoniosa (Md=5,20) e inferiores para a paixão obsessiva (Md=2,20). As comparações em função do sexo revelaram diferenças para paixão obsessiva (p=0,003), com valores superiores para os universitários do sexo masculino (Md=2,70) quando comparados ao sexo feminino (Md=2,00). Quando considerado o tempo de experiência da musculação, observou-se que os universitários que praticam a mais de um ano (Md=5,30) apresentaram valores superiores de paixão harmoniosa (p=0,04) quando comparados aos que praticam a menos de um ano (Md=4,90). Ao correlacionar a autoestima e a paixão em função do sexo dos praticantes, identificou-se correlação positiva e fraca entre a paixão harmoniosa e a autoestima nos praticantes do sexo masculino (r=0,396; p<0,05). CONCLUSÃO: Os universitários praticantes de musculação apresentam elevada autoestima e mostram-se apaixonados pela sua atividade. Além disso, para os homens, verificou-se que quanto maior a autoestima maior a paixão harmoniosa pela sua atividade.ABSTRACT. Evaluation of self-esteem and passion for bodybuilding in college students who frequent a gymBACKGROUND: Self-esteem is a psychological aspect that reflects in several areas of individuals’ lives, including the practice of physical exercise. In the same perspective, passion is an important motivational variable that corresponds to the way the individual treats an activity, for which demands time and energy. OBJECTIVE: To analyze self-esteem and passion in college students who practice weight training. METHODS: Participated in this research with a cross-sectional descriptive character, 96 college students (48 men and 48 women), with mean age of 21.90±3.10 years, practicing bodybuilding in the school gym of the State University of Maringá - PR, Brazil. The instruments used were an identification form, Rosenberg Self-Esteem Scale and Passion Scale. The Kolmogorov-Smirnov, Mann Whitney’s U test, and Spearman’s correlation coefficient were used to analyze the data, using p<0.05. RESULTS: Overall, the results showed that college students had high self-esteem (Md=32.00), higher values for harmonious passion (Md=5.20) and lower values for obsessive passion (Md=2.20). Comparisons according to gender revealed differences for obsessive passion (p=0.003), with higher values for male college students (Md=2.70) when compared to female students (Md=2.00). When considered the time of experience in bodybuilding, it was observed that college students who have been practicing for more than a year (Md=5.30) presented higher values of harmonious passion (p=0.04) when compared to those who have been practicing for less than a year (Md=4.90). When correlating the self-esteem and passion in function of the practitioner’s sex, it was identified a positive and weak correlation between harmonious passion and self-esteem in male practitioners (r=0.396; p<0.05). CONCLUSION: The college students who practice weight training present high self-esteem and show passion for their activity. Moreover, for males, it was verified that the higher the self-esteem the higher the harmonious passion for their activity.

Posttraumatic nuchal pseudolipoma in a high school athlete after weight training

Pseudolipomas are an uncommon clinical manifestation appearing as a non-encapsulated prominence of subcutaneous fat on MRI. Post-traumatic pseudolipomas (PTLs) are thought to arise from neoadipogenesis following acute or chronic trauma. These are most commonly located on the lower extremities, gluteal, and trochanteric regions. Here, we report a case of PTL in a high school athlete, arising in the posterior neck after weight training with performing barbell squats without neck padding. To our knowledge, this case represents a novel association between PTLs and weight training exercises.
