Difference In Standardized Repetitions Completed At 1- Repetition Maximum Load Percentages For Women, Aaron Rinehart, Andrew A. Wolfe, Matt Laurent
International Journal of Exercise Science: Conference Proceedings
In resistance training, a given training load is determined by two factors, volume (number of repetitions completed) and intensity (weight lifted). The current literature clearly recognizes an inverse relationship between the weight lifted and repetitions completed. The previous studies establishing intensity-to-repetition ratios predominantly utilized male participants. Research has yet to explore and determine appropriate resistance training intensity-repetition ratios for females. PURPOSE: Furthermore, the purpose of the study was to examine the relationship between achieved repetitions and load lifted (a percentage of 1RM) of college females. METHODS: Subjects included 11 females with six month of consistent resistance training experience. Each participant …

International Journal of Exercise Science: Conference Proceedings
One group of measures against the COVID-19 pandemic have been the non-pharmaceutical interventions (NPIs). NPIs taken by the NCAA included suspension of athletic seasons. Suspended championships during the pandemic have decimated the world of sports and led to changes in athletic role identity and social connectedness, which negatively affected student-athletes’ mental health (MH). One psychological characteristic that has the potential to support the MH and well-being of athletes is mental toughness (MT). MT is associated with successful sport performance and positive MH outcomes. Although empirical evidence supports the effectiveness of educational-based psychological skills training (PST) in promoting MH, similar effects …
An Extended Period Of Carbohydrate Mouth Rinsing Prior To Consumption Has No Additive Benefit On Cycling Performance, Henry D. Gebhardt, Eric J. Jones, Dustin P. Joubert
An Extended Period Of Carbohydrate Mouth Rinsing Prior To Consumption Has No Additive Benefit On Cycling Performance, Henry D. Gebhardt, Eric J. Jones, Dustin P. Joubert
International Journal of Exercise Science: Conference Proceedings
Due to limited glycogen stores, carbohydrate (CHO) consumption during exercise is effective at improving performance in endurance events lasting longer than 90 minutes in duration. Recent research has established that CHO mouth rinsing may improve performance over shorter durations, independent of actual consumption. However, research is lacking in determining if an extended period of mouth rinsing has any additive benefit in conjunction with typical CHO beverage consumption over longer competition durations, where CHO ingestion/consumption is likely warranted. PURPOSE: Determine the effects of CHO mouth rinsing combined with consumption compared to CHO consumption alone on cycling performance. METHODS: Following …
