Abstract

Adapted physical education and general physical education teachers may face challenges in teaching and promoting general physical activity and fitness. Implementing functional fitness activities, which integrate motor skills to carry out activities for daily living, may help teachers to effectively engage students with autism spectrum disorder (ASD) to become more active. Because students with ASD often lack motor coordination and have low levels of physical activity, functional fitness training can be a fun and effective tool that helps them improve their fitness levels and potentially assists them in their activities of daily living. The purpose of this article is to demonstrate how simple functional fitness activities can improve activities of daily living that require strength, endurance, flexibility, and stability. These activities are meant to be stimulating and purposeful. Keywords: autism; ASD; physical education; fitness, Autism spectrum disorder (ASD) is characterized by two categories in which individuals with ASD demonstrate deficits in social interaction and communication and/or resistance to change (American Psychiatric Association, 2013).

Abstract

The present paper aimed to systematically review case studies on physique athletes to evaluate longitudinal changes in measures of body composition, neuromuscular performance, chronic hormonal levels, physiological adaptations, and psychometric outcomes during pre-contest preparation. We included studies that (1) were classified as case studies involving physique athletes during the pre-contest phase of their competitive cycle; (2) involved adults (18+ years of age) as participants; (3) were published in an English-language peer-reviewed journal; (4) had a pre-contest duration of at least 3 months; (5) reported changes across contest preparation relating to measures of body composition (fat mass, lean mass, and bone mineral density), neuromuscular performance (strength and power), chronic hormonal levels (testosterone, estrogen, cortisol, leptin, and ghrelin), physiological adaptations (maximal aerobic capacity, resting energy expenditure, heart rate, blood pressure, menstrual function, and sleep quality), and/or psychometric outcomes (mood states and food desire). Our review ultimately included 11 case studies comprising 15 ostensibly drug-free athletes (male = 8, female = 7) who competed in various physique-oriented divisions including bodybuilding, figure, and bikini. The results indicated marked alterations across the array of analyzed outcomes, sometimes with high inter-individual variability and divergent sex-specific responses. The complexities and implications of these findings are discussed herein. [ABSTRACT FROM AUTHOR]

Abstract

Introduction. This article summarizes the clinical practice guidelines (CPG) for the diagnosis and treatment of diabetic retinopathy and diabetic macular edema of the Health Social Security of Peru (EsSalud). Objective. To provide clinical recommendations based on evidence for the diagnosis and treatment of diabetic retinopathy and diabetic macular edema in EsSalud. Methods. A guidelines elaborating group (GEG) was conformed by medical specialists and methodologists. The GEG formulated 4 clinical questions intended to be answered by this CPG. For each of these questions systematic searches of systematic reviews and primary studies (when considered pertinent) were carried out in PubMed during 2018. Evidence was selected in order to reply each of the proposed clinical questions. The certainty of the evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. During periodic working meetings, the GEG used the GRADE methodology to review the evidence and formulate the recommendations, points of good clinical practice and the management flowchart. Results. The present CPG addressed 4 clinical questions of four topics: screening, diagnosis, treatment of choice and adjuvant treatment. Based on these questions, 6 recommendations (4 strong and 2 conditional), 19 points of good clinical practice, and 1 management flowchart were formulated. Conclusion. This article summarizes the methodology and conclusions based on evidence from the CPG for the diagnosis and treatment of diabetic retinopathy and diabetic macular edema in EsSalud, Introducción.

Author

Siu, Alejandro and Escalante, Guillermo

Abstract

Objective: To determine our experience with laparoscopic hysterectomy. Design: Patients from private hospitals, attended from January 1997 to December 1999. Material and Methods: Fifty patients were subjected to laparoscopic hysterectomy, uterine arteries were sectioned and in many cases the cardinal ligaments were partially sectioned as well. The uterus was removed vaginally. Results: Eighteen of them (36%) had previously received estrogen therapy. Average age was 43 year-old, 6 of them (12%) nulliparous, the remainder (88%) had had a previous pregnancy, with an average number of 3,5 gestations. Surgical indications were uterine myomata, benign ovarian cysts, adenomyosis, endometriosis, chronic pelvic pain, dysfunctional uterine bleeding and entero-pelvic adhesions. Anteroposterior colpoperineorraphy was done in 16 patients (32%). Average surgery time was 103 minutes. Uterine weight averaged 236 g. Among complications, we identified two urinary tract infections (4%), one dome infection, one vesical laceration (2%) in the patient whose uterus weighted 600 g, and one abdominal wall haematoma caused by trocar. Average hospital stay was 2,8 days. Conclusions: Comparing this technique with conventional hysterectomy, we have observed longer duration of surgery, but faster postoperative recuperation, shorter hospital stay, faster remission of pain and it was possible to remove the uterus vaginally in patients with a prolapsed uterus and strong pelvic adhesions. Objetivo: Determinar nuestra experiencia en histerectomía laparoscópica. Diseño: Estudio retrospectivo. Lugar: Pacientes de clínicas privadas atendidas de enero de 1997 a diciembre de 1999. Material y Métodos: Cincuenta pacientes sometidas a histerectomía laparoscópica, en las que se llegó a seccionar las arterias uterinas y hasta los ligamentos cardinales, con tiempo vaginal para la extirpación de la pieza. A 18 (36%) se les administró estrogenoterapia previa. Resultados: El promedio de edad de las pacientes fue 43 años, 6 de ellas (12%) nulíparas, el resto (88%) había gestado alguna vez; promedio de gestaciones 3,5. Las indicaciones fueron miomas del útero, quistes benignos de ovario, adenomiosis-endometriosis, síndrome dolor pélvico crónico, hemorragia uterina disfuncional y adherencias pélvico intestinales. En pacientes con prolapso uterino, la colpoperineorrafia anteroposterior se realizó en dieciséis pacientes (32%). El tiempo operatorio promedio fue 103 minutos. El peso promedio uterino fue 236 g. Las complicaciones fueron dos (4%) infecciones urinarias, una (2%) infección de cúpula, una (2%) laceración vesical (en la paciente cuyo útero pesó 600 g) y un (2%) hematoma de pared ocasionado por uno de los trócares. La estancia de internamiento fue 2,8 días promedio. Conclusiones: Comparando esta técnica con la histerectomía convencional, apreciamos que, si bien el tiempo quirúrgico es mayor, las pacientes se recuperan más rápidamente, la estancia de internamiento es menor, la sintomatología dolorosa remite más rápido y permite el abordaje vaginal a aquellas pacientes con prolapso y adherencias pélvicas firmes.

Abstract

Background and objective: Topical aminophylline, caffeine, yohimbe, l‐carnitine, and gotu kola (Centella asiatica) may aid in reducing body fat. Lipoxyderm™ contains these ingredients and was used to test if fat loss of the thigh, in conjunction with a low intensity exercise program and restricted calorie intake, was enhanced via the topical application of this lotion. Methods: This was a double‐blind, placebo‐controlled, within‐group study that investigated the effects of Lipoxyderm™ on thigh fat mass, circumference, and skinfold thickness. Seven participants underwent pre/post‐exercise testing for weight, bilateral thigh circumference/skinfold thickness, and body composition/thigh fat mass assessment via dual‐energy X‐ray absorptiometry. Participants followed a hypocaloric diet, walked 150 minutes/wk, and were randomly assigned to apply a placebo to one leg and Lipoxyderm™ to their other leg for 28 days. Separate two‐way mixed factorial repeated measures ANOVAs were used to compare the effects of Lipoxyderm™ to the placebo on thigh circumference, skinfold thickness, and fat mass. Results: A significant time x group interaction was found for thigh circumference (F1,6 = 18.2, P = 0.005), skinfold thickness (F1,6 = 14.6, P = 0.009), and fat mass (F1,6 = 37.1, P = 0.001). Conclusions: A twice‐daily topical application of Lipoxyderm™ for 28 days compared to a placebo combined with a walking program and a restricted caloric intake is more effective at reducing thigh circumference (1.2 vs 0.8 cm), thigh skinfold thickness (3.7 vs 2.0 mm), and thigh fat mass (100.0 g vs 57.3 g).

Abstract

CrossFit® has been defined as a constantly varied, high intensity, functional movement strength/conditioning program that has seen a large increase in popularity. Few studies have specifically investigated either injury patterns, injury incidence (per 1000 hours), and/or injury prevalence sustained in the sport. Material and Method. Eighty-eight males (31.3 ± 8.4 yrs, 1.74 ± 0.06 m, 79.45 ± 12.02 kg) and 71 females (31.3 ± 9.1 yrs, 1.62 ± 0.07 m, 60.75 ± 9.37 kg) filled the survey to completion and were included in this investigation. The survey covered demographics, length of time performing CrossFit®, average number of days per week/minutes per workout performing CrossFit®, injuries obtained during CrossFit® within the last 12 months, and specific characteristics of injuries sustained. This was a descriptive survey study. Results. Participants reported an average of 4.3 ± 0.9 CrossFit® workouts per week at an average of 1.19 ± 0.37 hours per workout. More than half of the participants (50.3%) reported only doing CrossFit® as their mode of exercise; the other 49.7% reported doing sports such as running/swimming/weightlifting. Seventyfour participants reported 127 CrossFit® related injuries, yielding an injury prevalence of 46.5% and an estimated incidence of 3.3 per 1000 hours. Of the 127 injuries reported, the most commonly injured body parts were the shoulder (33.1%), low back (18.1%), knees (12.5%), wrists (10.2%), and elbows (5.5%). Only 1 case of rhabdomyolysis (0.8%) was reported. There was a significant relationship between getting injured and length of time in doing CrossFit® (p < 0.01) and getting injured and participating in CrossFit® competitions (p = 0.02). Conclusion. The injury incidence rates in this study are similar to those reported in other CrossFit® and weightlifting studies and less than those reported in American football and soccer studies. Participants that compete in CrossFit® competitions and have been doing CrossFit® for longer periods of time are also more likely to sustain an injury related to CrossFit®. [ABSTRACT FROM AUTHOR]

Abstract

This study compared the effects of Versa Gripps® compared to no grips on pull-ups to failure in and surface electromyographic (sEMG) signal amplitude during pull-ups on the wrist flexors (WF), wrist extensors (WE), latissimus dorsi (LAT), and infraspinatus (INF) muscles in strength-trained females. Material and Method. Seventeen healthy females volunteered to participate in the study. Pull-ups were performed to failure to the beat of a metronome. Surface EMG was computed using the root-mean-square (RMS) of the signal intensity with a sampling frequency of 1000 Hz, integrated over 500 ms, and normalized to the maximum voluntary contraction (MVC) for the muscles being investigated. EMG data from the four muscles and number of pull-ups performed were analyzed using paired two tailed t-tests for Grip and No Grip conditions for each muscle and for the number of pull-ups performed. Results. There was a significant decrease (p = 0.035) in EMG activation of the wrist extensors with grips (102.6 ± 65.5% MVC) compared to no grips (89.5 ± 49.2% MVC). No change was noted in EMG activation during pull-ups of the infraspinatus, latissimus dorsi, wrist flexors, or in the number of pull-ups to failure. Conclusion. Wrist straps may be effective at decreasing the demand of the wrist extensors during pull-ups. This may be beneficial for those strength-training participants recovering from lateral epicondylitis who wish to perform pulling exercises and need to unload the wrist extensors. Furthermore, strength-training participants may be able to more effectively recruit larger muscle groups in pulling exercises as smaller muscle groups may be a limiting component when performing pulling exercises.

Abstract

Aim. This study compared surface electromyographic (sEMG) signal amplitude during pull-ups with Versa Gripps® to those without grips on the dominant side wrist flexors (WF), wrist extensors (WE), latissimus dorsi (LAT), and infraspinatus (INF) muscles among strength-trained males. Material and Method. Thirty healthy males volunteered to participate in the study. All subjects reviewed, completed, and signed an informed consent form approved by Institutional Review Committees. Surface EMG was computed using the root-mean-square (RMS) of the EMG signal, integrated over 500 milliseconds, and normalized to the maximum voluntary contraction (MVC) for the muscles being investigated. EMG data from the four muscles were analyzed using paired two tailed t-tests for each individual muscle for Grip to No Grip conditions. Results. The comparisons revealed that the WE and WF sEMG were significantly less with the Versa Gripps® compared to No Grip. There were no significant differences between the Grip and No Grip conditions for the LAT and INF. Conclusion. These results suggest that the effort required by the WE and WF can be reduced with the use of Versa Gripps® in strength-trained males while performing a pull-up without inhibiting the recruitment of the LAT and/or the INF. This finding could be beneficial for strength-trained males suffering or recovering from lateral or medial epincondylitis because the decreased activation of the WE muscles during the pull-up exercise may help unload of the WE and WF which may aid in their recovery.

Abstract

The purpose of this study was to compare body composition measurements with best practice pre-test conditions and controlled non-best practice pre-test conditions using bioimpedance spectroscopy (BIS), ultrasound (US), skinfolds (SF), dual x-ray absorptiometry (DXA), and the four compartment (4C) model.Eighteen resistance-trained individuals participated. On day 0, participants logged all activities including food, fluid, and exercise. Participants arrived at the lab the next morning, day 1, following best-standardized practice protocols (fasted and non-exercised for 12 hours). Participants were measured with the 4 methods. Participants continued to log their activity and returned to the lab 4-7 hours later to repeat the same testing protocol in a non-best practice state. Continuing to log their activity, individuals did not report to the lab for testing on day 2 but were instructed to repeat their logged activities from day 0. Individuals reported back to the lab for re-testing on day 3, repeating the procedures/activities/food log from day 1. The reliability analyses indicated excellent stability of scores, with values ranging from 0.89 to 0.99. Repeated measures ANOVAs were used to determine if the BF% estimates were different between time points of day 1 and day 3. The results indicated there was a significant main effect for method (p= 0.003) where 4C, BIS, SF, and US all reported significantly lower values than DXA. In conclusion, body composition measurements were not significantly affected by following an unstandardized best practice protocol when compared to testing in a standardized best practice protocol.

Abstract

Sports nutrition encompasses a variety of components that play a role in influencing the dietary habits of athletes, and consequently, their athletic performance. The purpose of this study was to compare student-athletes’ nutritional knowledge and perceived dietary intake to their measured body composition. Participants included male and female Division II collegiate athletes at California State University, San Bernardino (age: 22 ± 2.1 years; height: 68.1 ± 4.7 in; body mass: 153.1 ± 32.1 lbs; fat-free mass: 117 ± 26.3 lbs; body fat percent: 24.4 ± 7.5%). Body composition was assessed using Bio-Electrical Impedance Analysis. Participants completed a validated abridged sports nutrition knowledge questionnaire. The athletes answered 15.2 ± 4% of the questions correctly with no differences observed between the sexes (females: 15.2 ± 3.7% vs. males: 15.2 ± 4.9%;p= 0.99). There were no significant correlations found between quiz scores and fat mass (p= 0.32), fat free mass (p= 0.41), or body fat percentage (p= 0.76). A significant difference was found between the athletes measured and perceived body fat percentages (3.7 ± 9.8;p= 0.02).The present study found that although Division II collegiate athletes have a low level of sports nutrition knowledge,there is no significant relationship between nutritional knowledge and body composition measures.
