How many times per week should a muscle be trained to maximize muscle hypertrophy? A systematic review and meta-analysis of studies examining the effects of resistance training frequency

Training frequency is considered an important variable in the hypertrophic response to regimented resistance exercise. The purpose of this paper was to conduct a systematic review and meta-analysis of experimental studies designed to investigate the effects of weekly training frequency on hypertrophic adaptations. Following a systematic search of PubMed/MEDLINE, Scoups, and SPORTDiscus databases, a total of 25 studies were deemed to meet inclusion criteria. Results showed no significant difference between higher and lower frequency on a volume-equated basis. Moreover, no significant differences were seen between frequencies of training across all categories when taking into account direct measures of growth, in those considered resistance-trained, and when segmenting into training for the upper body and lower body. Meta-regression analysis of non-volume-equated studies showed a significant effect favoring higher frequencies, although the overall difference in magnitude of effect between frequencies of 1 and 3+ days per week was modest. In conclusion, there is strong evidence that resistance training frequency does not significantly or meaningfully impact muscle hypertrophy when volume is equated. Thus, for a given training volume, individuals can choose a weekly frequency per muscle groups based on personal preference.     

Assessing Student Openness to Inquiry-Based Learning in Precalculus

Abstract

The authors have completed a 2-year quasi-experimental study on the use of inquiry-based learning (IBL) in precalculus. This study included six traditional lecture-style courses and seven modified Moore method courses taught by three instructors. Both quantitative and qualitative analyses were used to investigate the attitudes and beliefs of the students in each section. In this article, we provide a summary of those results with a particular focus on the Openness to IBL survey we developed for assessing student preferences for either student-centered or teacher-centered instruction. Although the majority of the students exhibited a strong preference for direct instruction, students whose scores favored student-centered approaches according to the survey also tended to perform better on the final exam, indicating that a key element to success in an IBL course may be students’ perceptions of the method.     

去多伦多,你准备好了?

Dear Brad, I will study abroad in the middle of July,in Toronto,Canada.I want to ask you something about the luggage pack.Although I have searched the Intemet,there are many different versions.Could you give me some advice about packing? Besides,I am really nervous since I am afraid that I can't catch the lesson and may have no friends there.I hope people around me are all kind and helpful like you!
