ABSTRACT

The purpose was to determine if Event Rehearsal Imagery (ERI) and Internal guided Imagery with Distractions (IGID) resulted in improvements in the running performance of college students. The participants (N = 74) were students at Kenyatta University in Nairobi, Kenya. Cooper’s 12 min run test was used to assess running performance. Following 8-weeks of training, findings indicated that there was a statistically significant difference (0.05 level) in running performance between the Event Rehearsal Imagery (n = 29), Event Rehearsal Imagery with Distractions (n = 16) and the Control group (n = 29). Overall, there was a significant mean difference in running among male (n = 47) and female (n = 27 participants).

ABSTRACT

The year of the Olympics is a special time for athletes everywhere. Health care professionals find it difficult to recognize a case of Chronic Fatigue of a former college track athlete who persisted on despite her infirmity to qualify for the Olympics. The patient had an acute onset of symptoms not consistent with any condition but general fatigue. Blood studies and additional tests indicated a fatigue syndrome consistent with that of Chronic Fatigue Syndrome. She was placed on a specific nutritional program for four months and shortly afterward was back to long distance running.

Effects of Circuit Resistance Training on Body Composition and Bone Status in Young Males

Submitted by Yilmaz Ucan

Dr. Ucan is the chairman of the AIBU Sports Club and is responsible for the university fitness and health center.

ABSTRACT

The purpose of this study was to determine the effects of circuit type resistance training on body composition and bone status in young males. Twenty eight moderately active male volunteers were randomly assigned to 12 weeks of circuit resistance training (CRT) (n=15; 24.3±1.4 years) or control (C) (n=13; 24.8±2.1 years). Total body fat (%BF), fat mass (FM), fat-free mass (FFM), bone mineral content, and bone mineral density (BMD) measurements were performed with dual-energy X-ray absorptiometry. At the end of the 12-week training period, there was a decrease (p<.05) in the CRT group %BF (-1.63%), FM (-1.03kg), an increase in FFM (1.46kg), and no change (p>.05) in body weight or BMD. In C, no significant (p>.05) changes were observed. CRT bone mineral density values were significantly (p<.05) higher (.003g/cm²) after the 12 week training period versus the control group values (-.005g/cm²).

Results suggest that 12 weeks of circuit resistance training in moderately active young males had a positive effect on body composition and bone status, with no effect on body weight. Additional studies may identify effects of circuit resistance training on body composition and bone mineral density in women and aging.

Disordered Eating, Eating Attitudes, and Reasons for Exercise among Male High School Cross Country Runners

Submitted by Guy Wadas, MS, Southern Utah University and Mark DeBeliso, PhD, Southern Utah University

ABSTRACT

PURPOSE: This study investigated the prevalence of disordered eating behaviors among male high school cross country runners. The study identified behaviors and feelings about being an athlete, and determined relationships between motivations to exercise and disordered eating behaviors. METHODS: Sixty-eight male high school cross country runners from 12 high schools in one urban school district completed three questionnaire packets on one occasion pre-season. The EAT-26 questionnaire was used to determine prevalence of disordered eating. The ATHLETE questionnaire was used to determine psychological factors for relationships with disordered eating. The EMI-2 was used to determine motivations to exercise and the relationship to disordered eating. EAT-26 scores and data from the EMI-2 and ATHLETE questionnaires were analyzed via a Pearson Correlation Coefficient. RESULTS: A modest positive relationship existed between exercising for disordered eating behaviors versus exercising for weight management (r = 0.31: p < 0.05), the Your Body in Sports subscale (which measured drive for thinness and performance) (r = 0.36: p < 0.05), and the Feelings about Performance subscale (or Performance Perfectionism) (r = 0.26: p < 0.05). CONCLUSIONS: Risk factors associated with eating disorders exist in high school male cross country runners. Underreporting and lack of recognition of disordered eating may affect prevalence rates. Recommendations include a longitudinal study of male high school runners across the school year to determine relationships with the timing of questionnaire administration. APPLICATIONS IN SPORT: Disordered eating behaviors should be acknowledged as more than a “female only” issue. Parents, teachers, coaches, and athletic trainers may be better able to understand and help male athletes with disordered eating behaviors or an active eating disorder.

Caffeine Improves Sprint-Distance Performance among Division II Collegiate Swimmers

Submitted by David F. Vanata, Ph.D., RD, CSSD, LD; Nick Mazzino, B.S.;Robert Bergosh, Ph.D. and Paul Graham, B.S. of Ashland University in Ashland, Ohio.

ABSTRACT

Caffeine has been identified as a possible ergogenic aid for athletic performance. The objective of this study was to evaluate the effects of caffeine on sprint-distance swim trials. Caffeine dosages of 3 milligrams per kilogram (mg^.kg^-1) of body weight and placebos were administered via vegan capsules to 30 Division II collegiate swimmers, (60.0% males, n=18), in a single blind, crossover study design. Capsules were administered 30-minutes prior to completing a 50-yard time trial using electronic touch-pads. Urine samples were collected and analyzed via High Pressure Liquid Chromatography (HPLC) to determine the amount of caffeine excreted in the urine. Significant improvements were observed between caffeine and placebo time trials, M=27.27 seconds, SD=3.65 vs. M=27.51 seconds, SD=3.74, t(29)=2.81, p=.009, respectively. Overall, 70.0% of all swimmers improved 50-yard swim times (n=21), with 61.1% (n=11) of males improving and 83.3% (n=10) of females. There was a significant difference between urinary caffeine levels after ingesting the placebo vs. the caffeine capsules, M=.733 micrograms per milliliter (mg^.ml^-1), SD=1.29 vs. M=2.69 mg^.ml^-1, SD=2.02, t(29)= -5.34, p<.001, respectively. Following supplementation, female swimmers excreted significantly more urinary caffeine than males, M=3.59 mg^.ml^-1, SD=2.23 vs. M=2.09 mg^.ml^-1, SD=1.68, t(28)= -2.11, p=.044, respectively.

Overall, caffeine supplementation was found to significantly improve time trials of trained colligate swimmers. Additional studies are needed to identify factors associated with the variation of urinary caffeine excretion values observed between female and male athletes.
