Title: The effect of short term isokinetic training on limb velocity.
Creator: Brown, Lee Edward, Florida Atlantic University, Whitehurst, Michael, Maslin-Ostrowski, Patricia
Abstract/Description: Strength increases following short-term bouts of isokinetic training have been demonstrated in the past without regard to limb velocity adaptations. This has been attributed to increased neuromotoric efficiency, rather than peripheral muscular hypertrophy. The purpose of this study was to determine the effects of a short-term isokinetic training regimen on limb velocity. Sixty subjects volunteered to participate and were randomly assigned to one of three groups; control (10 males, 10 females)...

This has been attributed to increased neuromotoric efficiency, rather than peripheral muscular hypertrophy. The purpose of this study was to determine the effects of a short-term isokinetic training regimen on limb velocity. Sixty subjects volunteered to participate and were randomly assigned to one of three groups; control (10 males, 10 females), slow (10 males, 10 females) and fast (10 males, 10 females). Each group was pre-tested by performing five repetitions of concentric/concentric knee extension/flexion movements at 60 and 240 d/s on a Kin-Com isokinetic dynamometer. The slow (60 d/s) and fast (240 d/s) groups then completed two days of training (separated by 48--72 hours) consisting of three sets of eight repetitions while the control group did not train. All groups were post-tested at 7--9 days after the pre-test. Data were collected from the middle three repetitions at 1000 Hz and separated into three velocity ROM phases of acceleration (ACCROM), load range (LR) and deceleration (DCCROM) along with peak force. Four univariate (ACCROM, LR, DCCROM & Force) four-way (2 velocities x 2 genders x 2 times x 3 groups) mixed factorial ANOVA's were performed to analyze the data. Results demonstrated significant decreases in ACCROM and increases in LR between pre and post-tests for the slow group at the slow velocity (ACCROM-1.25 +/- .04 deg vs 1.08 +/- .03 deg; LR-74.80 +/- .11 deg vs 75.35 +/- .09 deg) and for the fast group at the fast velocity (ACCROM-14.24 +/- .33 deg vs 13.59 +/- .29 deg; LR-39.73 +/- .32 deg vs 40.59 +/- .25 deg). Force and DCCROM exhibited no significant differences between testing days for any group. These results collectively point to short-term isokinetic training resulting in velocity specific increased limb velocity. These acute improvements may be explained as the result of neural adaptations, such as increased motor unit recruitment or firing rate, rather than hypertrophic responses due to the relatively short duration of the training stimulus. Furthermore, these accelerative increases produce a more rapid rate of force development which may be important in activities necessitating explosive movement, including sporting events requiring power.

Measurement of inspiratory elastic work (inew), inspiratory resistive work (inrw), and expiratory resistive work (exrw) was done using an esophageal balloon. Measured variables included VO$\sb2$, V$\rm\sb{E}$, V$\rm\sb{T}$, frequency of breathing (f), inew, inrw, and exrw, (work expressed in joules). There were no significant differences in VO$\sb2$, V$\rm\sb{E}$, V$\rm\sb{T}$ or f between groups ($\rm p>0.05$). No significant difference was found at peak exercise between groups (mean $\pm$ SD; Placebo; inew, $1.1\pm0.6$ J, inrw, $1.4\pm0.8$ J, exrw $2.2\pm1.8$ J; Active; inew, $1.0\pm0.5$ J, inrw, $1.3\pm0.7$ J, exrw, $1.8\pm0.9$ J; $\rm p>0.05$). Wearing an external nasal dilator does not significantly reduce the work of breathing during exercise.

Additionally, A significant group-by-time interaction was found from pre-to-RIH for BDNF expression in PBMCs (P= 0.046). Further, significant correlations were found between BMI and waist circumference (r= .91, P< 0.001), WHR (r= .51, P= 0.002) and Pre-to-RlH ratio (r=0.58, P=0.008). Young obese subject's BDNF response to maximal exercise was consistent with previous studies. Post-exercise BDNF expressed in PBMCs were significantly higher than rest suggesting immunological-neuroprotective interactions in the CNS.

Title: The role of airflow limitation in exercise-induced arterial hypoxemia.
Creator: Miller, Joshua M., Florida Atlantic University, O'Kroy, Joseph A.
Abstract/Description: The role of airflow limitation (AFL) in exercise-induced arterial hypoxemia (ElAH) was examined in six well-trained competitive cyclists. Two maximal cycle ergometer tests were performed, one while breathing room air (RA; 79% N2, 21% O2) and another breathing a mixture of heliox (He; 79% He, 21% O2) in random order. EIAH was estimated via pulse oximetry of HbSaO2. The results revealed no subject experienced AFL breathing RA or He. Despite a significant increase in V˙Emax (RA = 114.3 +/-...

Despite a significant increase in V˙Emax (RA = 114.3 +/- 27.6 l/min; He = 129.2 +/- 25.5 l/min; p < 0.05) during He condition there was no difference in HbSaO2 during maximal exercise (RA = 95.3 +/- 1%; He = 96.7 +/- 1.5%; p > 0.05). In conclusion, our subject population failed to show any significant decrease in HbSaO2 breathing RA, which makes it difficult to determine if AFL plays a role in EIAH.

Forty-six participants were randomly assigned to the experimental group (n = 24) or control group (n = 22). The experimental group participated in Zumba® for 8 weeks, 3 days per week, along with completing exercise rating scales and fitness tests. Outcome measures included agility, endurance, rate of perceived exertion (RPE), exercise motivation, and exercise self-efficacy. Agility, endurance, and RPE were measured by three fitness tests; Timed Up and Go (TUG) test, the Six-Minute Walk Test (6MWT), and Modified Borg Dyspnoea (MBD). Physiological outcomes were measured before the intervention (pretest), 4 weeks during the intervention, and after the intervention (posttest). The experimental group completed a follow-up of all three fitness tests 2 weeks after the removal of the intervention. A paired t test assessed the continuous measures within each group.

Pre-exercise levels were also assessed prior to the second and third sessions of week 1 and 6. Lastly, resting levels were measured before and after training intervention. No group differences (p>0.05) were detected for either biomarker. An acute BDNF elevation (p=0.018) was detected only in the final week of training. IL-6 elevations were detected at all acute measurements (p<0.01). BDNF and IL-6 percentage change correlated significantly (p<0.05) in week-1. No chronic alterations were observed (p>0.05).

METHODS: Thirteen untrained female subjects (33-50 years old) were recruited: oophorectomized (Group O = 5) and premenopausal controls (Group C = 8). Two separate visits included: body composition and maximal treadmill exercise test; followed by substrate utilization via open-circuit spirometry during 45 minutes of treadmill walking at 50% VO2max. RESULTS: When controlling for multiple variables affecting whole-body substrate utilization (age, VO2max, physical activity, body composition, fasting glucose, menstrual phase and diet), there was no difference in substrate utilization between pre- and postmenopausal women as measured by respiratory exchange ratio (RER) (0.83 ± 0.04 v 0.84 ± 0.03, p=0.47). CONCLUSIONS: Menopausal status does not appear to have an effect on substrate utilization during submaximal exercise in younger women.

Sixty minutes following supplementation, participants performed a one repetition maximum (1RM) barbell bench press test and repetitions to failure at 60% of 1RM. Heart rate and blood pressure were assessed at rest, 60 minutes post-consumption, and immediately following completion of repetitions to failure. Repeated measures ANOVA indicated a significantly greater bench press maximum with caffeine (p<0.05) (52.9 « 11.1 kg vs. 52.1 « 11.7 kg) with no significant differences between conditions in 60% 1RM repetitions (p=0.81). Systolic blood pressure was significantly greater post-exercise, with caffeine (p<0.05) (116.8 « 5.3 mmHg vs. 112.9 « 4.9 mmHg). Our findings indicate a moderate dose of caffeine may be sufficient for enhancing strength performance in resistance-trained women.

Oxygen content of OW (13.1 +/- 1.5 mgO2L-1 ) was higher than PL (6.0 +/- 0.1 mgO2L -1) (p<0.05) but lower than manufacture's claims. Thus, superoxygenated water did not result in any improvements in endurance exercise performance.

Sixteen participants (9 obese and 7 normal-weight) completed HIIE and CME in a randomized fashion. Our results showed a significant time effect for CTRP9 immediately following acute HIIE and CME in both groups. Furthermore, both significant treatment by time and group by time interactions for FMD were observed following both exercise protocols, with greater CME-induced FMD response in obese subjects than normal-weight subjects. Additionally, a positive correlation in percent change (baseline to peak) between CTRP9 and FMD was observed following acute CME. These findings support acute CME for improvement of endothelial function in obesity. Furthermore, the novel results from this study provide a foundation for additional examination of the mechanisms of exercise-mediated CTRP9 on endothelial function.

Fifteen subjects (8 obese and 7 normal-weight) were recruited to participate in an acute HIIE protocol. Our results demonstrated a significant elevation across time in plasma cfDNA and IL-6 immediately following acute HIIE, with no difference between obese and normal-weight subjects. Furthermore, cfDNA was not correlated with IL-6 in response to acute HIIE in either group. These findings indicate that the obese state does not further exacerbate the release of acute HIIE-induced inflammatory mediators (cfDNA and IL-6), which suggests that HIIE training may serve as a time-effective exercise strategy to improve obesity-associated inflammation.

It was hypothesised that short femurs and total height would be related to slower ACVs and lower total number of repetitions performed. 58 resistance trained subjects were recruited and attended one day of data collection. Subjects performed 1RM testing of the back squat followed by two single repetition sets at 30-90% of 1RM and a 70% of 1RM set to fatigue. There was no significant correlation between femur length and height with ACV at any intensity (p>0.05). A significant negative correlation existed between both height (r=-0.39, p=0.003) and femur length (r=-0.31, p=0.018) with total number of repetitions performed.

A subset of FAMuSS study data (n = 319, females = 183, males = 136) was randomly split into two groups (A & B). Group A pre-training data for female BM, female CSA, male BM, and male CSA models produced scaling exponents of 1.08, 0.44, 0.63, and 0.68, respectively. The female BM model was deemed inappropriate due to non-normal distribution of residuals. All other models met statistical criteria including normal distribution of residuals. Cross-validation to Group B pre-training data revealed that the models were appropriate, with the possible exception of male CSA model. Twelve weeks of resistance training did not alter the relation between BM, CSA, and muscular strength assessed by allometric scaling.

Title: The effect of cadence on time trial performance in novice female cyclists.
Creator: Graham, Patricia., College of Education, Department of Exercise Science and Health Promotion
Abstract/Description: The purpose of this study was to determine the effect of cadence on time trial performance in novice female cyclists. Ten novice female cyclists volunteered to participate in this study. Participants performed 3 sessions: one VO2 peak and two time trials (TT). Cadence was randomly selected and fixed for each TT (60 or 100 rpm) while power output (PO) was adjusted by the participant, as tolerated. Finish time, HR, blood lactate, PO, VO2, and RPE were measured throughout the time trials. The...

Participants performed 3 sessions: one VO2 peak and two time trials (TT). Cadence was randomly selected and fixed for each TT (60 or 100 rpm) while power output (PO) was adjusted by the participant, as tolerated. Finish time, HR, blood lactate, PO, VO2, and RPE were measured throughout the time trials. The major finding of this study was the significantly faster (p<0.05) finish time (minutes) during the 60 rpm condition (34:23) versus the 100 rpm condition (37:34). Also the 60 rpm TT resulted in significant (p<0.05) differences for HR (155.9 vs 161.2 bpm), gross efficiency (21.1% vs 17.7%), and PO (147 vs 129 watts). These results indicate that novice female cyclists benefit from adopting a low cadence during an 8k TT.

Title: Relationships Between Diet and Physical Activity Lifestyle Factors and Body Composition, Waist Circumference, and Body Mass Index in Postmenopausal Women.
Creator: Jansen, Mary, Zoeller, Robert F., Florida Atlantic University, College of Education, Department of Exercise Science and Health Promotion
Abstract/Description: PURPOSE: The purpose of this study was to compare relationships between dietary and physical activity (PA) behaviors and body composition and body fat distribution, as measured by percent body fat (BF%), waist-to-height ratio (WHt), waistto- hip ratio (WHp) and body mass index (BMI) in post-menopausal women (Post), with the same relationships in pre-menopausal women (Pre). METHODS: Ninety-two subjects (n = 48 Post; n = 44 Pre) were measured for height, weight, waist and hip circumferences and...

METHODS: Ninety-two subjects (n = 48 Post; n = 44 Pre) were measured for height, weight, waist and hip circumferences and skinfold thicknesses. Dietary content was obtained from a Diet History Questionnaire (DHQ II); PA was estimated from responses to the International Physical Activity Questionnaire (IPAQ). RESULTS: Multiple regression identified no modifiable predictor variables for Pre. Models for Post identified saturated fat grams (SFGs), PA, years postmenopause (YrsPost), and Alcohol (Alc) as predictors of WHt, WHp, BMI and BF%. CONCLUSIONS: PA, SFG and Alc are modifiable variables related to postmenopausal body composition and fat distribution.
