The effects of a period without physical training on the civilian population are well established. However, no studies show the effects of a period without mandatory physical training on maximum oxygen uptake (VO2 max) and anthropometric parameters in naval cadets. This study aimed to investigate changes in VO2 max and anthropometric parameters after 12 weeks without mandatory physical training in naval cadets. The sample was 38 healthy and physically active naval cadets. The measured variables, including VO2 max and anthropometric parameters, were evaluated through the 12-minute race test (12MRT) and the somatotype. Both variables had a separation of 12 weeks without mandatory physical training. A t-test for related samples was used to evidence changes between the test and post-test; effect size was calculated through Cohen’s d-test. Distance in 12MRT and VO2 max showed significant decreases at the end of 12 weeks without mandatory physical training (p < 0.001). Likewise, the tricipital skinfold thickness and the endomorphic component showed significant increases (p < 0.05). 12 weeks without mandatory physical training significantly reduces the VO2 max in naval cadets. Simultaneously, the same period without physical training increases both the tricipital skinfold thickness and the endomorphic component in this population.

El objetivo de este estudio fue analizar los efectos provocados por un periodo de entrenamiento en la pretemporada sobre las variables antropométricas y derivadas en jugadores de baloncesto de élite. En la presente investigación participaron ocho jugadores profesionales de la liga ACB, con una edad de 26,8±5,4 años. Se realizaron dos valoraciones cineantropométricas aplicando los criterios establecidos por la International Society for the Advancement of Kynanthropometry. La primera medición (pre-test) se realizó justo antes de comenzar la pretemporada, mientras que la segunda medición (post-test) fue realizada 14 días después. Se encontró una disminución significativa del peso, el pliegue de la cresta ilíaca, abdominal y muslo, el perímetro de la cintura, el sumatorio de seis y ocho pliegues, la ratio cintura/cadera y en el porcentaje y peso graso. También se halló un aumento significativo del porcentaje de masa muscular. En conclusión, se ha hallado que catorce días de pretemporada son suficientes para provocar cambios en algunos parámetros antropométricos, sobre todo los relacionados con la adiposidad, así como en la composición corporal, más concretamente sobre la masa grasa y muscular.Abstract. The aim of this study was to analyze the effects of a preseason training focused on anthropometric and derived variables in elite basketball players. Eight professional players from ACB, with a mean age of 26.8±5.4 years old, participated in this study. Anthropometric evaluations were taken according with the criteria of the International Society for the Advancement of Kynanthropometry. The first test was done before the preseason began (pre-test), meanwhile the second one was taken 14 days after (post-test). Significant decreases were found in weight, iliac crest, abdominal and thigh skinfolds, waist girth, six and eight skinfold thickness sums, waist/hip ratio, and fat percentage and mass. Also, muscle mass significantly increased. In conclusion, fourteen preseason training days are sufficient to produce changes in some anthropometric parameters, especially those related to adiposity, as well as in body composition, specifically in fat and muscle mass.

Introduction: Patan Academy of Health Sciences (PAHS) in Nepal has adopted problem-based learning (PBL) as principal pedagogy to foster attributes predefined for its medical graduates. This study evaluates reaction of participants in PBL tutor-training program focused on PBL process and its assessment.Methods: An orientation program was organized separately for 24 faculty members and 45 higher secondary science majoring students prior to conduction of real-time PBL tutorial sessions. Faculty’s reaction as PBL tutors was collected before and after the orientation program using a 13- item self-administered questionnaire. Internal consistency reliability of the questionnaire items and outcome of the training program were assessed using Cronbach’s alpha, coefficient of variation, Shapiro-Wilk test, paired t-test and adjusted effect size for dependent samples.Results: The pre-test internal consistency reliability was high (0.89) whereas it was acceptable (0.69) for post-test. The average score increased from 26.50 to 34.55 and standard deviation decreased from 5.39 to 2.70 between pre- and post-test. Difference between post- and pre-tests total scores followed normal distribution and suitable parametric test (paired t-test) revealed the difference was highly significant (p< 0.0001). The adjusted effect size was high (1.65) for small dependent samples.Conclusions: The faculty training for PBL and assessment was helpful in implementing PBL pedagogy at PAHS.Journal of Patan Academy of Health Sciences, Vol. 2, No. 1, 2015. page: 30-34
