Resistance training exercise selection: efficiency, safety and comfort analysis method

Objective. To evaluate whether three-dimensional (3D) musculoskeletal modelling could be effective in assessing the safety and efficacy of exercising on a seated row resistance-training machine. The focus of the evaluation was on biomechanical and anthropometric considerations of the end user.Methods. Three anthropometric cases were created; these represented a 5th percentile female as well as a 50th and a 95th percentile male based on body mass index. Two repetitions, with a resistance equal to 50% of the functional strength of one repetition maximum (1RM) for each anthropometric case, were performed.Results. Results indicate that the default model of the LifeModeler software has important limitations that should be taken into consideration when used to evaluate exercise equipment. Adjustments had to be made to the model to solve the forward dynamics simulations; as a result, no muscle forces or contraction values were obtained. This negatively influenced the value of the results as these parameters are important when analysing an exercise. The seated row resistance-training machine’s engineered or manufactured adjustability was sufficient, as it appeared to accommodate the three anthropometric cases adequately during execution of this exercise.Conclusion. It appears that 3D musculoskeletal modelling can be used to evaluate resistance-training exercises such as the seated row; however, the limitations indicated by this study must be taken into consideration, especially when using the default LifeModeler model

Objetivo: El objetivo de la presente investigación fue determinar el efecto del orden de ejecución de ejercicios contra resistencia (CR) sobre la presión arterial (PA) en reposo de jóvenes estudiantes normotensos. Método: Para el estudio se contó con la participación de 14 hombres sanos, familiarizados con el ejercicio de contra resistencia con edad promedio de 23.3 ± 1.4 años. Las condiciones experimentales fueron realizadas en orden aleatorizado, en diferentes días de trabajo y consistieron en: (1) iniciar el ejercicio CR con grupo muscular grande y terminar con pequeños (G-Peq), (2) iniciar con grupos musculares pequeño y finalizar con grandes (P-Gde) y (3), condición control .La rutina de ejercicio constó de ocho ejercicios los cuales se trabajaron al 60% de 1 repetición máxima (RM), se realizaron 3 series de 10 repeticiones para cada ejercicio , las mediciones de presiones arteriales se tomaron antes del ejercicio, al terminar el ejercicio y cada 10 minutos luego de terminar la rutina durante 1 hora. Resultados: En la PA sistólica se encontraron disminuciones importantes durante 30 min tanto de la condición G-Peq como de la P-Gde en comparación con el grupo control (p≤ 0.001), no obstante, la magnitud de la disminución fue mayor posterior a G-Peq (6-11 mm Hg) en comparación con P-Gde (4-10 mm Hg). Para la PA diastólica no se encontró interacción significativa (p=0.39). Conclusión. Existe efecto hipotensor posterior a ambas rutinas, sin embargo, se observó una disminución mayor de la PA sistólica al finalizar la rutina con grupos musculares grandes. Abstract. Objective: The aim of this study was to determine the effect of the order of execution of resistance training exercises (RT) on blood pressure (BP) in normotensive young students at rest. Method: 14 healthy men (mean age of 23.3 ± 1.4 years) who were familiar with resistance training participated in this study. The order of participation for the experimental conditions was randomized; the different conditions consisted in: (1) RT starting with large muscles groups and finishing with small ones (L-S), (2) RT starting with small muscles groups and ending with large ones (S-L) and (3) the control condition. RT routine consisted of eight exercises with intensity of 60% of one repetition maximum (RM). The participants performed 3 sets of 10 repetitions for each exercise. Blood pressure measurements were taken before exercise, at the end of the year, and every 10 minutes after finishing the routine for 1 hour. Results: systolic BP reduction was found for 30 min both in L-S and S-L compared with the control group (p ≤ 0.001), although the magnitude of the decrease was higher after L-S (6-11 mmHg) compared with S-L (4-10 mmHg). For diastolic BP no significant interaction was found (p=0.39). Conclusion There exists a hypotensive effect after both routines; however, there was a greater decrease of systolic BP at the end of the routine with large muscle groups.

Fast bowlers have the highest injury rates in cricket; therefore, reducing these injuries is a priority for coaches and the support staff. Improving physical conditioning and monitoring bowling workload are primary preventative strategies to reduce overuse injuries. The objective of this study was to investigate practices of cricket coaches in Australia on (1) strength and conditioning and (2) bowling workload management of junior and non-elite fast bowlers. A web-based survey was sent to 548 male Level Two cricket coaches registered with Cricket New South Wales, Australia. One hundred and seventy (31%) coaches responded to the survey. A majority (70%) of the coaches were working with cricketers under the age of 19 years. Only 39 (23%) engaged fast bowlers in resistance training exercises. Coaches under the age of 40 years were more likely to prescribe resistance training (χ2 = 5.77, df = 1, p = 0.016) than coaches over the age of 40. Lower back, abdominal and gluteal muscles were the most commonly targeted muscle groups. Sit-ups, core work and squats were the most common exercises prescribed. Most (92%) coaches were aware of current national fast bowling workload recommendations. However, only 18 (13%) coaches prescribed the currently recommended workloads. The results indicate that coaches training junior and sub-elite cricketers need more awareness on of the importance of engaging fast bowlers in resistance training and monitoring bowling workloads. Understanding current training practices of coaches can assist in the development of injury prevention programmes for junior fast bowlers and educational programmes for coaches.

In this study, an analysis of independent studies dealing with occupational safety training in different learning environments, in which various learning materials are used, was carried out. As a method, meta-analysis method was used. For this purpose, databases were used to collect national and international articles and papers suitable for the purpose of the study. Studies that did not mention the tools, equipment and environment used in education in the collected studies were excluded from the research, and 18 studies were included in the meta-analysis. The data obtained studies are categorized according to the education models, the sectors in which the education is applied and the characteristics of the participants in the education. As it is known, occupational health and safety procedures aim at a healthy and reliable working environment for its employees. However, the ultimate goal is to raise not only employees but also future generations with this awareness. The most important instrument of this is undoubtedly education. For this reason, it is necessary to develop training models suitable for the work environment, age, gender and every conceivable situation.

Experimental Group

Adults with an intellectual disability have significantly lower levels of fitness compared with the general population. This study examined the effects of a 13-week theoretically guided, community-based, multicomponent resistance training intervention, resistance training for empowerment, on muscular strength and independent functional performance in 24 adults with an intellectual disability, aged 18–44 years. Twelve participants were randomly allocated to an experimental group and 12 to an active control group. An analysis of covariance revealed that the experimental group had significantly greater increases (p < .05) on the chest press and leg press one-repetition maximum tests and the 6-min walk test from the baseline to postintervention compared with the control group. The experimental group correctly and independently performed a significantly greater number of steps of resistance training exercise tasks than the control group. Marginal significance and large effect sizes were found for the prone plank test and the stair climb test. The resistance training for empowerment was effective in promoting muscular strength and independent functional performance among adults with an intellectual disability.
