ABSTRACT Introduction Although resistance training (RT) can provide numerous benefits for both men and women, morphological, neuromuscular, metabolic, physiological, and behavioral differences between sexes may influence the magnitude of training responses. Objective To analyze the impact of 16 weeks of progressive RT on strength endurance in untrained men and women. Methods Twenty-eight men and 31 women (18-30 years) underwent a supervised RT program that was divided into two 8-week stages, 3 times per week on nonconsecutive days. The RT program was composed of exercises for different body segments (trunk, upper and lower limbs) that were performed with three sets of 8-12 repetitions maximum (RM), in 10 and 12 exercises, in the first and second stage, respectively. Strength endurance was assessed in 3 exercises (bench press, squat, and arm curl) and in a combination of these exercises through a protocol composed of 4 sets performed to failure with 80% of 1-RM on the baseline, after 8 and 16 weeks of RT. Results Group vs. time interactions (p <0.05) were found for bench press (men = +28.3% vs. women = +32.1%), squat (men = +13.5% vs. women = +32.7%), and arm curl (men = +20.2% vs. women = +24.4%) exercises, as well as in the set of all 3 exercises (men = +18.4% vs. women = +31.2%). Conclusion Our results suggest that 16 weeks of RT can improve strength endurance in both men and women, although higher gains are achieved by women.

The Impact

Objective. The objective of this paper is to compare the impact of supervised walking and resistance training upon the walking distance in PAD patients. Materials and Methods. The examination involved 50 PAD patients at the 2nd stage of the disease according to Fontaine’s scale. The participants were randomly allocated to two groups: one exercising on the treadmill (n=24) and one performing resistance exercises of lower limbs (n=26). Results. The 12-week program of supervised rehabilitation led to a significant increase in the intermittent claudication distance measured both on the treadmill and during the 6-minute walking test. The group training on the treadmill showed a statistically significant increase of the initial claudication distance (ICD) and the absolute claudication distance (ACD) measured on the treadmill, as well as of ICD and the total walking distance (TWD) measured during the 6-minute walking test. Within the group performing resistance exercises, a statistically significant improvement was observed in the case of parameters measured on the treadmill: ICD and ACD. Conclusions. The supervised rehabilitation program, in the form of both walking and resistance exercises, contributes to the increase in the intermittent claudication distance. The results obtained in both groups were similar.

ABSTRACT Introduction: Aging is inevitable and irreversible, but with the advancement of technology, life expectancy is increasing every year, bringing proposals for various interventions to improve the quality of life. One such intervention is physical exercise programs. Objectives: To investigate the impact of multicomponent training in circuits on functional autonomy parameters in elderly women. Methods: Elderly were recruited and distributed in two groups: trained (N = 16) and non-trained (N = 15). Those in the trained group performed 75-minute training sessions twice a week over a 56-week period. The resistance training included upper and lower limbs with a relative intensity of 70% of 1RM, exercises using body weight, stretching and specific tasks for agility, performed in a circuit form and totaling three passages. Participants underwent functional autonomy (FA) assessment by the protocol of the Latin American Developmental Group for Maturity, the 6-minute walk test (T6M), and the sit-and-reach (SR) test. Results: The trained group had a significant decrease in body weight (p=0.02) and body mass index (p=0.015). Significant improvements (p=0,009) were also observed in FA, SR, and T6M after the intervention Compared with the untrained group, the trained group also obtained significant differences in all functional parameters analyzed. Conclusion: A long-term multicomponent training program conducted on a circuit and applied twice a week was enough to improve multiple components of the functional autonomy of elderly women.

Abstract Purpose: The current study aims to examine weight stigma and sociocultural attitudes toward appearance among lesbian, gay, and bisexual (LGB) individuals and heterosexual men and women. Methods: The sample consisted of heterosexual and LGB men and women. Participants were drawn from introductory psychology classes and a variety of supplemental recruitment methods (Facebook, Instagram, Reddit, MTURK, etc.). Results: Individuals identifying as male and individuals identifying as heterosexual had significantly greater weight bias than individuals identifying as female and individuals identifying as LGB. Additional gender identity and sexual orientation mean group differences among sociocultural attitudes were observed. While there were modest associations between weight bias and overall sociocultural attitudes, gender identity and sexual orientation had little impact on the strength of these associations. Conclusion: This investigation contributes to knowledge of the impact of gender identity and sexual orientation on weight stigma and sociocultural attitudes toward appearance.Level of EvidenceIII: Evidence obtained from cohort or case–control analytic studies.

Background: Powerlifting consists of the squat, bench press, and dead lift, and extreme loads are lifted during training and competitions. Previous studies, which have defined an injury as an event that causes an interruption in training or competitions, have reported a relatively low frequency of powerlifting injuries (1.0-4.4 injuries/1000 hours of training). No previous study has investigated the prevalence of injuries, defined as a condition of pain or impairment of bodily function that affects powerlifters’ training, in a balanced sample of men and women, and no studies have established possible risk factors for an injury. Purpose: To investigate the prevalence, localization, and characterization of injuries among Swedish subelite classic powerlifters, with an emphasis on differences between men and women, and to investigate whether training and lifestyle factors are associated with an injury. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 53 female and 51 male Swedish subelite powerlifters answered an online questionnaire including questions about background characteristics, training habits, and lifestyle factors. The main part of the questionnaire included questions about injuries and their consequences. An injury was defined as a condition of pain or impairment of bodily function that affects powerlifters’ training. Results: Seventy percent (73/104) of participants were currently injured, and 87% (83/95) had experienced an injury within the past 12 months. The lumbopelvic region, shoulder, and hip were the most commonly injured areas for both sexes. Women experienced a significantly greater frequency of injuries in the neck and thoracic region than men. Injuries seemed to occur during training, although only 16% (11/70) of those currently injured had to completely refrain from training. Training frequency, greater personal best in the dead lift, injury onset during bench-press and dead-lift training, use of straps, alcohol consumption, and dietary issues were associated with current injuries. Conclusion: Injuries are very common in subelite powerlifters. Men and women report similar injury frequencies but different anatomic locations. These injuries do not prevent powerlifters from training and competing, but they may change the content of training sessions. Why powerlifters develop injuries is still unclear; however, it is likely that the management of training loads and optimization of the lifting technique during the squat, bench press, and dead lift are of importance.

Introduction: Prescription of resistance training (RT) is increasing among teenagers, requiring further studies to investigate the effects on this population. Objective: To examine the different orders on exercises sequence and its influence on the number of repetitions in teenager. Methods: Participated in the study 12 voluntarily male teenagers (14.91 ± 0.79 years, 1.69 ± 8.61 cm, 62.24 ± 7.26 kg) without experience in RT. After 48 hours of the last session of 10 repetitions maximum (10RM) test, subjects performed one of the four sequences of exercises in a counterbalanced crossover design. Four different sequences were also performed with a interval of 48 hours. All sequences were three sets of each exercise with 10RM load, with two-minute intervals between sets and exercises. The order of exercises was the sequence 1: bench press (BP), pulldown (PD), machine shoulder press (SP), biceps curl (BC) and triceps (TR); Sequence 2: TR, BC, SP, PD and BP; the sequence 3: Leg press (LP), leg extension (LE) and leg curl (LC); Sequence 4: LC, LE and LP. Results: Significant differences were observed (p <0.05) in the total number of repetitions for the BP exercises, SP, BC and TR for the sequence of the upper limbs and for the lower limbs and the LP and LE exercises. Conclusion: The results suggest that the performance of the average number of repetitions for sessions conducted with RT intensity of 10RM in teenagers was influenced by the different kind of exercises in both upper and lower limbs.

Objective: Retrospectively analyze surgical procedures performed on patients with insertional Achilles (calcaneal tendon) tendinopathy, focusing on outcomes and the impact on the patients’ functional quality. Methods: A descriptive, retrospective, case series study drawn up by collecting data directly from the patients’ medical records. For the functional analysis of patients, we used the questionnaire of the adapted American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS). An assessment was carried out on each of the patients who underwent surgery at our hospital from 2010 to 2019, using the surgical technique described in this article, i.e., resection of the affected portion of the tendon with its subsequent reinsertion. Results: All surgical patients achieved an improvement in their AOFAS score and in pain levels, with good functional performance only three months into the postoperative period, from 50.1 to 83.75 (p<0.001). Conclusion: The use of the technique proved very effective, particularly in terms of the maintenance of foot function and important improvement in pain levels, thus producing a relevant increase in function among patients. Level of Evidence IV; Therapeutic Study; Case Series.

Genu Varus

The deformities of the lower limbs (genu valgus and genu varus) are alterations frequently developed properly by physiological processes which usually disappear at 2 years (genu varus) and at 7-8 years (genu valgus), being considered in adults normal a 4º-6º genu valgus, however the appearance of the latter is also related to various metabolic pathologies, tumors, traumatic sequelae, infections, skeletal dysplastic and idiopathic genu valgus. In the bibliography, there is a greater consensus on the approach to varus deformity, not so in valgus deformities, where there is no bibliography with a level of evidence that defines established protocols to treat severe valgus deformities>20, currently good treatment results have been demonstrated by means of knee arthroplasty to correct genu valgus deformities, which showed good results in the alignment of the lower extremities through the balance of ligaments in patients with severe genu valgus with pain reduction. , improvements in knee function and with a low rate of complications, the use of these alternatives such as the external approach in total knee replacement in patients with severe genu valgus and medial collateral ligament insufficiency allows correcting large deformities using a technique simple and in most cases without the use of a prosthesis that generates a degree of constraint, progressively improving their living conditions.

Context: The rising incidence of physical activity– and sports-related injuries has prompted the present-day investigation of resistance training as a potential means of injury prevention and physical literacy development among youth. Evidence Acquisition: Relevant studies on the topics of athlete development, physical literacy, resistance training, and injury prevention in children and adolescents were reviewed (PubMed and Sports Discus, 1982-2016). Recommendations from consensus guidelines and position statements applicable to resistance training and injury prevention in youth, in addition to young athlete development, were reviewed. Additionally, hand searches, expert requests, article reference lists, and gray literature were utilized and reviewed for pertinent content. Study Design: Clinical review. Level of Evidence: Level 4. Results: Youth throughout the physical activity spectrum are at risk for physical activity– and sports-related injury. Of highest priority are early specializers, physically inactive youth, and young girls, owing to increased injury rates. Resistance training among these at-risk populations has been shown to reduce injury risk by up to 68% and improve sports performance and health measures, in addition to accelerating the development of physical literacy. Recent recommendations, position statements, and national initiatives advocate for the incorporation of resistance training with qualified instruction among these groups. Conclusion: Resistance training in addition to free play and other structured physical activity training can serve as a protective means against injury and a positive catalyst for the development of physical literacy to offset the impact of diminishing physical activity and early sport specialization in today’s youth.

The primary purpose of this investigation was to determine the impact of altering the set structure during an 8-week resistance training program on anthropometric, hormonal, and strength power characteristics. Thirty female volleyball players were recruited for participation and then randomly assigned to 1 of 3 resistance training groups: (i) cluster sets (CRT; n = 10), (ii) traditional sets (TRT; n = 10), or (iii) control (CON; n = 10). All athletes were evaluated for thigh and arm circumference, vertical jump, 20-m sprint, 4 × 9-m shuttle-run, 1-repetition maximum (1RM) back squat, bench press, military press, and deadlift prior to and after an 8-week periodized training intervention. Blood samples were taken before and after the 8-week training period to evaluate resting testosterone, cortisol, and insulin-like growth factor 1 responses to the training period. After 8 weeks of training the CRT group displayed a small but significant improvement in vertical jump (CRT: effect size (ES) = 038, 7.1%) performance when compared with the TRT group (ES = 0.34, 5.6%). Both the CRT and TRT training interventions resulted in very large increases in the 1RM squat (CRT: 8.4% ± 1.2%; TRT: 7.3% ± 0.6%), bench press (CRT: 8.3% ± 2.0%; TRT: 8.7% ± 1.9%), military press (CRT: 5.7% ± 1.2%; TRT: 5.5% ± 1.6%), and deadlift (CRT: 8.2% ± 1.6%; TRT: 8.3% ± 2.2%). There were no significant differences in 20-m sprint or 4 × 9-m shuttle run times between the CRT, TRT, and CON groups. These results suggest that cluster sets allow for greater improvements in vertical jump performance and equal improvements in strength gains to those seen with traditional sets.

Purpose: The purpose of this study was to assess the impact of developed minimally invasive operation such as the partial lateral facetectomy (PLFE) with patella thickness resection in patients with lateral patellofemoral (PF) osteoarthritis on short-term clinical and radiographic outcomes. Methods: This is a prospective study of 27 knees in 27 patients (18 females and 9 males, mean aged at surgery 59.1-year old) whom a PLFE with patella thickness resection using developed minimally invasive method was performed. Data of preoperative and postoperative questionnaires, physical examinations, and radiographs were analyzed. The minimum follow-up was 12 months (mean, 24.1 months; range, 12–36 months). Results: The subjective outcomes included the anterior pain relief assessed by scores using the Western Ontario and McMaster Universities Arthritis Index score (scores improved considerably by 2.34 points with respect to pain and by 1.63 points with respect to function), visual analog scale, and Knee Society Score (that improved in 78% of the knees). The majority of these patients experienced improvement in their PF symptoms. The PF index decreased considerably after surgery. The mean patellar width and thickness were decreased after surgery, maintaining a width/thickness ratio of 1.8:1.0 after surgery. Conclusion: PLFE with patella thickness resection aiming to decrease the high pressure in the lateral facet and improving congruence of the patella confirmed frequent pain relief. This surgical procedure is minimally invasive, relatively simple, and effective in selected patients and can be a valid early alternative to more complex operations. Level of Evidence: Level IV Therapeutic study.
