Effective academic advising in kinesiology is paramount to student success, contribution of the discipline to global health, and preparation of the workforce’s future leaders. Enrollment growth in kinesiology and its curricular breadth impose challenges that are unique from many other academic majors. The American Kinesiology Association convened a preworkshop titled “Advising in Kinesiology: Challenges and Opportunities” in January 2019 to begin dialogue related to advancing effective advising practices in kinesiology. Twenty-six attendees, all of whom were engaged in advising in different roles, participated in presentations and group discussions. This paper summarizes the preworkshop primary findings and offers some best-practice considerations. While it is clear that effective advising is positioned to advance the quality of kinesiology programs and our graduates, there is a dearth of supporting evidence, and addressing this through research is a needed priority.

This study examined the effects of serial reductions in energy and fluid intake on two simulated boxing performances separated by 2 days recovery. Eight amateur boxers (age: 23.6 ± 3.2 years; height 175 ± 5 cm; body mass [BM] 73.3 ± 8.3 kg [Mean ± SD]) performed two simulated boxing bouts (BB) under normal (N-trial) and restricted (R-trial) diets in a counterbalanced design over 5 days. The trials were separated by a 9-day period of normal dietary behavior (X-trial). BM was recorded on days 1, 3, and 5 of each trial. Simulated bouts of three, 3-min rounds with 1-min recovery were completed on days 3 (BB1) and 5 (BB2) of each 5-day trial. Punching force (N) was recorded from 8 sets of 7 punches by a purpose-built boxing ergometer. Heart rate (fC) was monitored continuously (PE3000 Polar Sports Tester, Kempele, Finland), and blood lactate (BLa) and glucose (BG) were determined 4-min post-performance (2300 StaPlus, YSI, Ohio). Energy and fluid intakes were significantly lower in the R-trial (p < .05). Body mass was maintained during the N-trial but fell 3% (p < .05) during the R-trial. There were no significant differences in end-of-bout fC or post-bout BG, but BLa was higher in the N- than the R-trial (p < .05). R-trial punching forces were 3.2% and 4.6% lower, respectively, compared to the corresponding N-trial bouts, but the differences did not reach statistical significance. These results suggest that energy and fluid restrictions in weight-governed sports do not always lead to a significant decrease in performance, but because of the small sample size and big variations in individual performances, these findings should be interpreted with care.
