  El desarrollo de la fuerza es relevante tanto para el rendimiento como para la salud. El propósito del presente estudio fue determinar los efectos del CrossFit en comparación con entrenamiento tradicional sobre distintas manifestaciones de la fuerza. Catorce adultos entrenados de ambos sexos fueron divididos aleatoriamente en dos grupos para realizar 8 semanas de entrenamiento: un grupo (CF; edad: 24.9 ± 1.6 años) realizó CrossFit y el otro grupo (ET; edad: 28.7 ± 4.6 años) realizó entrenamiento de fuerza tradicional. La carga de ambos fue equiparada con relación a la duración de la parte central de las sesiones. Todos los sujetos fueron evaluados con tests de fuerza máxima (Back Squat, Bench Press y Dead Lift), fuerza resistencia (Squat y Push-ups) y fuerza explosiva (Squat Jump y Abalakov) pre y post intervención. Se verificaron mejoras en ambos grupos en todas las variables analizadas (p < 0,05), pero no se hallaron diferencias entre grupos como consecuencia de los distintos programas de entrenamiento. Se concluye que ambos programas de entrenamiento son similarmente efectivas para desarrollar la fuerza máxima, la fuerza explosiva y la fuerza resistencia en adultos entrenados. Abstract: Muscular strength development in its different expressions forms is relevant for both sport performance and health. The purpose of the present study was to determine the effects of CrossFit training in comparison with traditional resistance training on different expressions of strength. Fourteen adults of both sexes, with strength training experience, were randomly divided into two groups to perform 8 weeks of training: one group (CF; age: 24.9 ± 1.6yrs) performed CrossFit and the other group (ET; age: 28.7 ± 4.6yrs) performed traditional strength training. The training load of both programs was equated in relation to the duration of the main part of the sessions. All subjects were tested for maximal strength (Back Squat, Bench Press and Dead Lift), endurance strength (Squat and Push-ups) and explosive strength (Squat Jump and Abalakov) before and after the intervention. Significant improvements were verified in both groups post intervention for all the variables analyzed (p <0.05), but no significant differences were found between groups as a consequence of the different training programs. It is concluded that both training modalities are similarly effective in developing maximal strength, explosive strength and endurance strength in trained adults.

Abstract Background Both athletes and recreational exercisers often perform relatively high volumes of aerobic and strength training simultaneously. However, the compatibility of these two distinct training modes remains unclear. Objective This systematic review assessed the compatibility of concurrent aerobic and strength training compared with strength training alone, in terms of adaptations in muscle function (maximal and explosive strength) and muscle mass. Subgroup analyses were conducted to examine the influence of training modality, training type, exercise order, training frequency, age, and training status. Methods A systematic literature search was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. PubMed/MEDLINE, ISI Web of Science, Embase, CINAHL, SPORTDiscus, and Scopus were systematically searched (12 August 2020, updated on 15 March 2021). Eligibility criteria were as follows. Population: healthy adults of any sex and age; Intervention: supervised concurrent aerobic and strength training for at least 4 weeks; Comparison: identical strength training prescription, with no aerobic training; Outcome: maximal strength, explosive strength, and muscle hypertrophy. Results A total of 43 studies were included. The estimated standardised mean differences (SMD) based on the random-effects model were − 0.06 (95% confidence interval [CI] − 0.20 to 0.09; p = 0.446), − 0.28 (95% CI − 0.48 to − 0.08; p = 0.007), and − 0.01 (95% CI − 0.16 to 0.18; p = 0.919) for maximal strength, explosive strength, and muscle hypertrophy, respectively. Attenuation of explosive strength was more pronounced when concurrent training was performed within the same session (p = 0.043) than when sessions were separated by at least 3 h (p > 0.05). No significant effects were found for the other moderators, i.e. type of aerobic training (cycling vs. running), frequency of concurrent training (> 5 vs. < 5 weekly sessions), training status (untrained vs. active), and mean age (< 40 vs. > 40 years). Conclusion Concurrent aerobic and strength training does not compromise muscle hypertrophy and maximal strength development. However, explosive strength gains may be attenuated, especially when aerobic and strength training are performed in the same session. These results appeared to be independent of the type of aerobic training, frequency of concurrent training, training status, and age. PROSPERO: CRD42020203777.

ResultsA total of 43 studies were included. The estimated average standardised mean differences (SMD) based on the random-effects model were -0.06 (95% CI: -0.20, 0.09, p=0.446), -0.28 (95% CI: -0.48, - 0.08, p=0.007) and -0.01 (95% CI: -0.16, 0.18, p=0.919) for maximal strength, explosive strength and muscle hypertrophy, respectively. The attenuation in explosive strength was more pronounced when concurrent training was performed within the same session (p=0.043) compared with separating the sessions by at least 3 h (p&gt;0.05). Summary/ConclusionConcurrent aerobic and strength training does not compromise muscle hypertrophy and maximal strength development. However, explosive strength gains may be attenuated, especially when aerobic and strength training are performed within the same session.

Bench press exercise is extensively used for chest and shoulder strength development. Joint stiffness is one of the side-effects that may occur with the exercise. This study aimed to investigate the relationship between bench press load and shoulder joint stiffness. Sixteen female rugby players (body weight 53.98 ± 7.14 kg, height 156 ± 5.38 cm) selected for Perak SUKMA 2018 team were assessed during centralized training ~9 months prior to the competition. Shoulder joint stiffness in terms of external and internal rotation range of motions were assessed by a qualified physiotherapist. The participants then performed one repetition maximum (1-RM) Bench press, according to the National Strength & Conditioning Association (NSCA)'s protocol.  Standardized warm-up and cooling-down protocol were prescribed to the participants accordingly. Pearson correlation coefficient was used for statistical correlation analysis. Both side shoulder internal and external rotation range of motion measurements showed a negative correlation (r=-0.190 internal, r=-0.285 external) with bench press (average 1-RM load 50.83 ± 9.00 kg) performance. Bench press exercises may result in reduced shoulder mobility due to an increase of muscular tightness around the joint. Maintaining normal mobility of shoulder joint throughout any strength training program is warranted and suggested. The finding also highlighted the importance of the mobility program to always be included together with a strength training programme for athletes.

Age-related influences on somatic and physical fitness of elite police agents Influencias de la edad en la aptitud física y somática de los agentes de policía de élite Background: Elite police officers must be physically fit to perform their job occupational demands but information on the effect of age in their physical fitness and somatic composition is scarce. Our aim is to describe the effect of age on somatic and physical fitness of a Special Police Unit (SPU); and to understand age-related changes. Methods: 117 SPU elements of a total of 218, aged 42.6±4.2 years, were assessed on their somatic (height, weight, circumferences, skinfolds); body composition (BMI, body fat); and physical fitness (maximal, power and endurance strength, aerobic power, and flexibility). T-tests were used for comparing results to other police studies. Regression analysis was used to detect the effect of age for somatic and fitness variable. Results: SPU elements showed a homogeneous and suitable fitness condition. No somatic differences were found along age, but annual age losses were found for physical fitness, namely for strength: left handgrip strength (95%CI -0.70 to -0.12), bench press (95%CI -2.34 to -0.89), squat jump (95%CI -0.70 to -0.12), medicinal ball throw (95%CI -0.62 to -0.25), push-ups (95%CI -1.64 to -0.66), pull-ups (95%CI -0.53 to -0.11), sit-ups (95%CI -1.33 to -0.27), but also on the VO2max (-0.535 to -0.115). Conclusions: Portuguese SPU elements showed a good somatic and physical fitness condition according to the requirements of their profession. Regardless the effect of age they were able to maintain a good somatic fitness and a very good aerobic power along the years. The loss of strength was the most associated with age.  Resumen. Introducción: Los agentes de policía de élite deben estar en buena forma física para cumplir con las demandas ocupacionales de su trabajo, pero la información sobre el efecto de la edad en su condición física y composición somática es escasa. Nuestro objetivo es describir el efecto de la edad sobre la aptitud física y somática de una Unidad Especial de Policía (SPU); y comprender los cambios relacionados con la edad. Métodos: Se evaluaron 117 elementos SPU de un total de 218, con edad de 42,6 ± 4,2 años, en su morfología (altura, peso, circunferencias, pliegues cutáneos); composición corporal (IMC, grasa corporal); y aptitud física (fuerza máxima, potencia y resistencia, potencia aeróbica y flexibilidad). Se utilizaron pruebas t-Student para comparar los resultados con otros estudios policiales. Se utilizó el análisis de regresión para detectar el efecto de la edad para la variable somática y de aptitud. Resultados: Los elementos SPU mostraron una condición física adecuada y homogénea. No se encontraron diferencias somáticas a lo largo de la edad, pero se encontraron pérdidas de edad anuales para la condición física, es decir, para la fuerza: fuerza de prensión (IC 95%: -0,70 a -0,12), bench press (IC del 95%: -2,34 a -0,89), squat jump (IC 95%: -0,70 a -0,12), lanzamiento de pelota medicinal (IC 95%: -0,62 a -0,25), extensiones de brazo (IC 95%: -1,64 a -0,66), flexiones de brazo (IC 95%: -0,53 a -0,11), abdominales (IC 95%: -1,33 a -0,27), pero también sobre el VO2 máx. (-0,535 a -0,115). Conclusiones: Los elementos SPU portugueses mostraron una buena condición física y somática de acuerdo con los requisitos de su profesión. Independientemente del efecto de la edad lograron mantener una buena condición somática y una muy buena potencia aeróbica a lo largo de los años. La pérdida de fuerza fue la más asociada con la edad.

Introduction: Periodization is the accurate manipulation of methodological variables of strength training (ST) to provide a progressive increase in the different manifestations of muscle strength. The most used models in ST are linear and undulatory periodization. Objective: Evaluate the effects of 24 weeks of training by applying three different models of ST periodization: Linear Periodization (LP), Weekly Undulating Periodization (WUP) and Daily Undulating Periodization (DUP) on: upper limb (UL) strength (submaximal and endurance), submaximal strength and power of the lower limbs (LL) and on other components of physical fitness (flexibility, agility and abdominal endurance strength). Methods: Experimental, longitudinal study, with a convenience sample, in which 29 people of both sexes participated, randomly allocated to the groups. Tests were performed pre- and post-intervention. ANOVA (two-way) of repeated measures was performed. Results: There was a significant increase in submaximal strength of the UL in the three periodization models: LP (p<0.001), the WUP (p=0.002) and DUP (p=0.001). There was also a significant increase in submaximal strength of the LL with LP (p=0.002), WUP (p<0.001) and with DUP (p=0.001). No significant intergroup differences were found in any test and time. Conclusion: In individuals without training experience, 24 weeks of TF provided gains in different manifestations of strength, regardless of the periodization model (LP, WUP or DUP). PL and WUP seem to be better at providing LL power gains in the horizontal jump.

The goal of this study was to assess the validity, reliability and accuracy of a smartwatch-based workout analysis application in exercise recognition, repetition count and One Repetition Maximum (1RM) prediction in the strength training-specific setting. Thirty recreationally trained athletes performed four consecutive sets of barbell deadlift, barbell bench press and barbell back squat exercises with increasing loads from 60% to 80% of their estimated 1RM with maximum lift velocity. Data was measured using an Apple Watch Sport and instantaneously analyzed using an iOS workout analysis application called StrengthControl. The accuracies in exercise recognition and repetition count, as well as the reliability in predicting 1RM, were statistically analyzed and compared. The correct strength exercise was recognised in 88.4% of all the performed sets (N = 363) with accurate repetition count for the barbell back squat (p = 0.68) and the barbell deadlift (p = 0.09); however, repetition count for the barbell bench press was poor (p = 0.01). Only 8.9% of attempts to predict 1RM using the StrengthControl app were successful, with failed attempts being due to technical difficulties and time lag in data transfer. Using data from a linear position transducer instead, significantly different 1RM estimates were obtained when analysing repetition to failure versus load-velocity relationships. The present results provide new perspectives on the applicability of smartwatch-based strength training monitoring to improve athlete performance.

SummaryThe aim of the study was to determine the levels of lower limb explosive strength of girls in different sport specialization. The sample consisted of 24 girls in aerobic gymnastics (n = 12) and athletic (n = 12) aged 10 to 12 years. To assess the levels of girls’ lower limbs explosive strength, we administered the following tests: countermovement jump test, countermovement jump with free arms test, squat jump test, 10-seconds repetitive jumping test. Testing sessions took place in September 2019. To obtain data about the levels of lower limbs explosive strength, we recorded step height (cm) and duration of the flight phase (s). Data about the lower limbs explosive strength were collected using the Optogait system for optical detection. We applied basic statistical characteristics, namely Student’s t-test and multivariate linear regression. There were no significant differences between girls in aerobic gymnastics and athletics. We recorded better test results in the group of girl’s athletes in the countermovement jump, countermovement jump with free arms and squat jump. In the group of girl’s involved in aerobic gymnastics, we recorded better results in the 10-second repetitive vertical jumping and vertical jump strength. According to the collected data, we may conclude that the training process of the selected girls in terms of explosive strength development is significantly different. Girls involved in aerobic gymnastics showed a higher level of performance in the 10-second vertical jump, which results from the structure of sport specificity.

Prior to major competitions, athletes often use a peaking protocol such as tapering or training cessation to improve performance. The majority of the current literature has focused on endurance-based sports such as swimming, cycling, and running to better understand how and when to taper or use training cessation to achieve the desired performance outcome. However, evidence regarding peaking protocols for strength and power athletes is lacking. Current limitations for peaking maximal strength is that many studies do not provide sufficient details for practitioners to use. Thus, when working with athletes such as powerlifters, weightlifters, throwers, and strongman competitors, practitioners must use trial and error to determine the best means for peaking rather than using an evidence-based protocol. More specifically, determining how to peak maximal strength using data derived from strength and power athletes has not been established. While powerlifting training (i.e., back squat, bench press, deadlift) is used by strength and power athletes up until the final days prior to a competition, understanding how to peak maximal strength relative to powerlifting performance is still unclear. Thus, the purpose of this study was to review the literature on tapering and training cessation practices relative to peaking powerlifting performance.
