The Effects Of Concurrent Activation Potentiation On Bat Swing Velocity Of Division Ii College Softball Athletes, Alexis Mace, Charles Allen
The Effects Of Concurrent Activation Potentiation On Bat Swing Velocity Of Division Ii College Softball Athletes, Alexis Mace, Charles Allen
International Journal of Exercise Science
International Journal of Exercise Science 13(1): 1630-1637, 2020. As an ethical and practical ergogenic strategy, concurrent activation potentiation (CAP), achieved by remote voluntary contractions (RVC) such as jaw clenching, has been proposed to acutely enhance muscular and athletic performance characteristics. The effects of CAP on bat swing velocity (BSV), an important component for successful hitting in sports such as baseball and softball has yet to be reported in the literature. The purpose of this research was to examine the effects of maximal jaw clenching on BSV in collegiate division II softball players. Thirteen (n = 13) division II softball …
Motivational Coaching Improves Intrinsic Motivation In Adult Fitness Program Participants, Victoria J. Gaesser, William M. Maakestad, Erik S. Hayes, Stephen J. Snyder
Motivational Coaching Improves Intrinsic Motivation In Adult Fitness Program Participants, Victoria J. Gaesser, William M. Maakestad, Erik S. Hayes, Stephen J. Snyder
International Journal of Exercise Science
International Journal of Exercise Science 13(5): 1167-1178, 2020. The purpose of this study was to measure intrinsic motivation following the implementation of motivational coaching strategies in a semester long personalized adult fitness program. Sixty individuals (40 female/ 20 male, age= 48 ± 15 yrs) participated as clients in an undergraduate exercise training program led by student trainers at Taylor University. The program took place during two consecutive semesters, therefore subject participation ranged from one to two semesters. In addition to personalized exercise prescription, student trainers implemented motivational strategies using a motivational coaching guide aimed at increasing individuals’ overall intrinsic motivation. …

Influence Of Fatigue On Planned Agility Performance In Soccer Players., Sofia K. Jakobsson, Tal Amasay
International Journal of Exercise Science
International Journal of Exercise Science 13(1): 656-666, 2020. We investigated the acute fatiguing effects of sprint interval training (SIT) on change of direction performance in male and female soccer players. A T-test was performed once before (PRE) and twice following (POST 1 and POST 2) the completion of four sets of 4 s cycle ergometer sprints protocol. The sprint intervals were separated by 25 s active recovery. POST 1 was performed approximately 25 s following the final cycle sprint and POST 2 began two minutes after completing POST 1. Repeated measures ANOVA and Bonferroni post hoc tests were used to …
Large Inter-Individual Differences In Responses To A Block Of High Intensity Aerobic Interval Training: A Case Series In National-Level Cyclists And Triathletes, Solfrid Bratland-Sanda, Frank G. Pedersen, Marius N. Haave, Jan Helgerud, Øyvind Støren
Large Inter-Individual Differences In Responses To A Block Of High Intensity Aerobic Interval Training: A Case Series In National-Level Cyclists And Triathletes, Solfrid Bratland-Sanda, Frank G. Pedersen, Marius N. Haave, Jan Helgerud, Øyvind Støren
International Journal of Exercise Science
International Journal of Exercise Science 13(2): 480-487, 2020. The aim was to investigate individual responses on VO2maxand performance to a block of high intensity aerobic interval training (HIIT) in national-level endurance athletes. METHODS: National-level cyclists and triathletes (five men and two women, 31 ± 3.3 years, VO2max65.1 ± 3.3 ml·kg-1·min-1) conducted 14 HIIT sessions (4x4 min uphill running at 90-95% maximal heart rate) in nine days during preseason. VO2maxin running and cycling, lactate threshold (LT) in cycling, oxygen cost of cycling (CC), and a cycling time-trial (TT) were …
Centesimal Age And Relative Age Effect In Elite Futsal Players, Dayse Dias Da Silva Carraco, Larissa Rafaela Galatti, Marcelo Massa, Irineu Loturco, Cesar Cavinato Cal Abad
Centesimal Age And Relative Age Effect In Elite Futsal Players, Dayse Dias Da Silva Carraco, Larissa Rafaela Galatti, Marcelo Massa, Irineu Loturco, Cesar Cavinato Cal Abad
International Journal of Exercise Science
International Journal of Exercise Science 13(6): 329-341, 2020. To investigate centesimal age (CA) and relative age effect (RAE) in elite male futsal players their date of birth and court-position were accessed through the official FIFA website. The absolute and relative frequency distributions of player births were quantified by quartiles and semesters. The two-way ANOVA and the Chi-Square analysis were applied to check for possible differences. The results showed a mean CA of 27.76 ± 4.11 years with no differences for both playing positions and competitions. In addition, no significant differences were found between quartiles or between semesters. The results suggest …
The Effects Of An Acute Bout Of Self-Myofascial Release On The Physiological Parameters Of Running, Debra A. Stroiney, Sarah Herrick, Jennifer Bossi, Vincent J. Paolone, Tracey Matthews
The Effects Of An Acute Bout Of Self-Myofascial Release On The Physiological Parameters Of Running, Debra A. Stroiney, Sarah Herrick, Jennifer Bossi, Vincent J. Paolone, Tracey Matthews
International Journal of Exercise Science
International Journal of Exercise Science 13(3): 113-122, 2020. This study examined changes in the physiological parameters of running performance when self-myofascial release (SMR) was used prior to a submaximal run. A total of 16 male recreational runners, between the ages of 27 and 50 years old volunteered for the study. Participants had to complete a running event measuring a 10K or longer in the past 12 months and obtained a O2peakvalue of 45 mL·kg-lmin-1to be included in the study. Participants took part in two 40 min treadmill runs at 75% of their O2peak …
