RESUMO
BACKGROUND: Although previous studies have reported that proprioceptive training methods (PTM) have positive effects, there is a relatively small number of studies regarding the impact of PTM in women's soccer. Therefore, there is a need to systematize the given results. In this regard, this systematic review aimed to investigate the effect of proprioceptive training methods in female soccer players. METHODS: The studies' search and analysis were done according to the PRISMA guidelines. The following databases were checked (Google Scholar, PubMed Cochrane and ProQuest), with additional publication time criteria (2000-2023) using the following keywords: proprioceptive, balance, neuromuscular, training, exercise, intervention, method, activity, female football players, female soccer players, woman soccer players. RESULTS: A total of 7 studies were included in the quantitative synthesis that meet all the criteria with the number of participants being 2.247. Based on the analysis of the previous research and detailed discussion, the main findings of the study resulted in the partial improvement of explosive strength (66%), strength (50%), muscle imbalance and flexibility (50%) and the prevention and reduction of lower extremity injuries in female soccer players (60%). Only one study reported no significant differences between groups, where rate of major injuries was higher in experimental group. CONCLUSION: The obtained results indicate the necessity to implement proprioceptive training in female soccer training programs, in order to influence the prevention and reduction of injuries and improve balance, proprioceptive ability and body control.
RESUMO
The aim of this research was to determine the influence of a 12-week program of aerobics mix on the parameters of body composition in healthy adult women. The research has been performed in a sample of 64 women participants, and it is divided into two groups, an experimental group (E), made of 34 women participants (age 32 ± 1.8 years), and a control one (C), made of 30 women participants (age 33 ± 0.5 years). Their anthropometric and body composition were evaluated using the following respective parameters: body height, body weight, body fat percentage, muscle mass percentage, skinfold-back (KNL), skinfold-upper arm (KNN), skinfold-stomach (KNT), and skinfold-thigh (KNNK). After mix aerobics realization, among the women of the E group, there is a reduction of body mass by -2.5% and waist size by -3.39%, while muscle mass increased by 2.26%. With all skinfolds within the participants of the E group, there is a statistically important gained reduction of p < 0.05 at the final measuring, compared with the initial one (upper arm -21.10%, stomach -14.36%, back -20.58%, and upper leg -13.98%). The reduction of body mass percentage was -10.59%, and that of body mass index was -2.5%. Based on the gained results, it can be concluded that the mix program was efficient in the reduction of the subcutaneous fat tissue and visceral fat and also influential on the increase of muscle mass.
RESUMO
SUMMARY: The primary aim was to gather available data published after the 2000s, on cardiovascular fitness in normal weight and obese children and adolescents. Based on the data, the secondary aims were to identify the most used outcomes and to determine the differences in cardiovascular fitness in the mentioned populations. Following PRISMA recommendations, multiple databases were searched: Google Scholar, PubMed, Cochrane Library, ProQuest, and Research Gate, with additional inclusion criteria: original study published in English, normal weight and obese children and adolescents as participant sample, studies that have assessed cardiovascular fitness parameters, and studies with participant's nutrition state. A total of 19 studies, with a total of 4,988 included participants (both obese and normal weight) were identified, with the most common participants have presented better results in terms of BMI, BF%, VO2max, VO2peak and METs, while the HR values are inconsistently presented. Despite deficiencies the study deficiency in the last two decades, there are differences in the mentioned populations. Further studies should focus on including the technology that reaches teens and families for overweight and obesity prevention and advancements in standard measurements for juvenile overweight and obesity, as well as for the creation, adaption, and validation of measuring instruments. As good framework for future directions, there is a need for more concise and unified measurements of cardiovascular fitness parameters in normally weight and obese children and adolescents.
El objetivo principal fue recopilar datos disponibles publicados después de la década del 2000 sobre la condición cardiovascular en niños y adolescentes con peso normal y obesos. En base a estos datos, los objetivos secundarios fueron identificar los resultados más utilizados y determinar las diferencias en la condición cardiovascular en las poblaciones mencionadas. Siguiendo las recomendaciones de PRISMA, se realizaron búsquedas en múltiples bases de datos: Google Scholar, PubMed, Cochrane Library, ProQuest y Research Gate, con criterios de inclusión adicionales: estudio original publicado en inglés, niños y adolescentes con peso normal y obesidad como muestra participante, estudios que hayan evaluado enfermedades cardiovasculares, parámetros de condición física y estudios con el estado nutricional de los participantes. Se identificaron un total de 19 estudios, con un total de 4.988 participantes incluidos (tanto obesos como con peso normal), siendo las variables más comunes: IMC, %BF, VO2máx, VO2pico, FC, PAD, PAS y MET. Generalmente, los participantes con peso normal han presentado mejores resultados en términos de IMC, %BF, VO2máx, VO2peak y MET, mientras que los valores de FC se presentan de manera inconsistente. Independientemente de la deficiencia de estudios en las últimas dos décadas, existen diferencias en las poblaciones mencionadas. Estudios futuros deberían centrarse en incluir tecnología que llegue a adolescentes y familias para la prevención del sobrepeso y la obesidad y avances en las mediciones estándar del sobrepeso y la obesidad juvenil, así como para la creación, adaptación y validación de instrumentos de medición. Como buen marco para direcciones futuras, se necesitan mediciones más concisas y unificadas de los parámetros de la condición cardiovascular en niños y adolescentes con peso normal y obesos.
