The purpose of this study was to determine if resistance exercise altered peripheral BDNF concentration. Eighteen trained male subjects were split into two groups performing varied repetition ranges. DUP-HR and DUP-LR groups trained 3x/week for 8 weeks, and were equated for total volume (repetitions X sets X intensity). Plasma BDNF and interleukin-6 (IL-6) levels were measured prior to and immediately following the first exercise session of weeks 1, 2, 4 and 6. Pre-exercise levels were also...

Eighteen trained male subjects were split into two groups performing varied repetition ranges. DUP-HR and DUP-LR groups trained 3x/week for 8 weeks, and were equated for total volume (repetitions X sets X intensity). Plasma BDNF and interleukin-6 (IL-6) levels were measured prior to and immediately following the first exercise session of weeks 1, 2, 4 and 6. 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).

This study examined if multi-joint resistance exercises could elicit expression of biomarkers associated with neuroprotection. Thirteen well-trained males performed 4 sets to failure at 80% of a one-repetition maximum (1RM) on the back squat, bench press, and deadlift. The biomarkers measured immediately pre- and post-exercise were brain derived neurotrophic factor (BDNF), insulin-like growth factor 1 (IGF-1), cathepsin B (CatB), and interleukin 6 (IL-6). There was a main time effect (p0.05)....

There was a main time effect (p<0.01) for BDNF with significant increases in the deadlift (p=0.01) and bench press (p=0.01) conditions, but not the squat (p=0.21). There was a main time effect (p<0.01) for IL-6 with a significant increase in the squat (p<0.01). There was no significant increase in CatB or IGF-1 (p>0.05). Additionally, there was no significant relationship between BDNF and IL-6 response.

Additionally, RPE calls were more accurate during set four vs. set one on the squat and deadlift at both the called 6 and 9 RPEs. Further bench press RPE calls were more accurate than squat and deadlift RPE at the called 6, while both bench and deadlift RPE calls were more accurate than squat RPEs at the called 9. Importantly across all sets all RPE calls assessed repetitions in reserve within one repetition of precision.

This study examined whether accuracy of intraset RIR predictions changes over time. Nine resistance trained men completed three bench press training sessions per week for six weeks, with the last set of each session performed until muscular failure. During the set to failure, subjects verbally indicated when they perceived 4 repetitions in reserve (RIR) and 1 RIR during the set. For each RIR prediction, the difference between perceived RIR and actual RIR was calculated as RIRDIFF. We analyzed...

Nine resistance trained men completed three bench press training sessions per week for six weeks, with the last set of each session performed until muscular failure. During the set to failure, subjects verbally indicated when they perceived 4 repetitions in reserve (RIR) and 1 RIR during the set. For each RIR prediction, the difference between perceived RIR and actual RIR was calculated as RIRDIFF. We analyzed differences in RIRDIFF using both the raw RIRDIFF (including positive and negative values) and the absolute values of all RIRDIFF using a factorial MANOVA. Covariates included proximity to failure of the RIR prediction, total repetitions performed per set, percentage of one-repetition maximum lifted, the week of training, and the session (1, 2, or 3 within each seek). For the raw RIRDIFF all covariates, except for percentage of 1RM (p > 0.05) were significantly related to the outcome measure at both the predicted 4 and 1 RIR (p < 0.001 to p = 0.04). Specifically, RIRDIFF was significantly higher in weeks 1-4 versus weeks 5-6 (p < 0.001 to p = 0.005). However, the only covariate which significantly impacted the absolute value RIRDIFF at both the predicted 4 (p = 0.033) and 1 RIR (p = 0.022) was total repetitions per set. These results indicate that trained men tend to shift from overpredicting to underpredicting RIR over time and that more repetitions in a set is related to more inaccurate RIR predictions. However, the actual accuracy (i.e., absolute value RIRDIFF) did not significantly change over six weeks of training.

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.

Twenty women and men (aged 18-50 years) participated in the study. Participants completed a yoga plus relaxation (YR) session and a relaxation only (R) session. The YR condition showed significant changes from baseline in HR (bpm, p < 0.001), RR (ms, p < 0.001), pNN50 (%, p = 0.009), LF (% p = 0.008) and HF (% p = 0.035). The R condition showed significant changes from baseline in HR (bpm, p < 0.001), RR (ms, p < 0.001), HF (ms2, p = 0.004), LF (%, p = 0.005), HF (%, p = 0.008) and LF/HF (%, p = 0.008). There were no significant differences between conditions for the changes from baseline for any of the variables. The results demonstrate that relaxation produces favorable changes in indices of heart rate variability whether alone or preceded by about of Hatha yoga.

Results: Both PU and RHR were significantly correlated to the HR response to CCO-CPR (r = - 0.45, p < 0.01; r = 0.54, p < 0.001). PU were significantly correlated to RPE: local muscular (r = - 0.43; p < 0.01), central (r = - 0.45; p < 0.01), and over-all (r = - 0.39; p < 0.01). Conclusions: Greater physical fitness lessens the metabolic and perceptual strain to CCO-CPR.

Both the control (N=155) and intervention (N=184) group consisted of a convenience sample of students from a 2000-level health course. A pre- and post-test questionnaire was administered to both groups which included questions regarding demographics, tobacco use, HBM, self-efficacy, and perceived stress. Data analysis included frequency counts, confirmatory factor analysis, Cronbach's alpha, and two-way ANOVA. Two-way ANOVA results indicated statistically significant differences for the Health Belief Model questions (p=0.002) and self-efficacy items (p=0.03). No statistical significance was found regarding perceived stress. These findings provide evidence an educational tobacco intervention administered at the college level can have a significant impact on students.

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.

Subsequently, and on different days, two graded tests were administered (with, without stockings) with 5 minute warm-up at 50 W followed by 5 minute stages at 60 %, 70%, and 80% of max power output. Following the last sub-maximal stage, participants performed 3 - 5 supramaximal trials. Each lasted 30 seconds at 200% of her peak power output with HR, RPE, and BLa measured at the end of each trial. Results: No significant difference was observed between conditions for any metabolic or perceptual measure across workloads while perceived muscle soreness at 24 hours trended towards significance (p=.067). Conclusion: Compression socks did not significantly alter metabolic or perceptual responses to cycling.

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.

Motor behavior and grip strength were measured pre- and post- intervention. Our results showed a significant increase in hippocampal BDNF expression in AT mice after a 9-week intervention. Further, AT mice were found to have higher concentrations of IGF-I, and improved motor behavior when compared to RT and CNT. No significant differences were observed in IGF-I concentration between RT and other groups. RT improved grip strength after nine weeks of training. These findings support the use of AT and RT as a tool to improve comorbidities found in Alzheimer’s disease.

Enjoyment in PE had no statistical significance in determining physical activity participation outside of school (p>0.05). Understanding the factors which influence physical activity participation can help inform future policies and strategies aimed at providing developmentally appropriate experiences, ultimately providing intrinsic motivation to seek out, and sustain, regular physical activity strategies aimed at providing developmentally appropriate experiences, ultimately providing intrinsic motivation to seek out, and sustain, regular physical activity participation.

RotaRod peak latency and grip strength were assessed as preand post-measurements. Skeletal muscle was collected after training and analyzed for cathepsin B protein. Tg+RT showed greater grip strength than Tg and Tg+AT at posttesting (p ≤ 0.05). Only Tg+AT showed an improvement in RotaRod peak latency (p ≤ 0.05). Gastrocnemius weight was greater in Tg+RT compared to Tg (p ≤ 0.05), and no differences were observed in cathepsin B or procathepsin B expression (p > 0.05). This data suggests that cathepsin B was not induced by either mode of exercise training, however, physical function and muscle mass were improved, therefore inclusion of both training modalities may address peripheral comorbidities in Alzheimer’s disease.

The purpose of this investigation was to determine the effects of a pedometer-based intervention on physical activity and self-efficacy among community college students in wellness classes (N = 154). The intervention included a pretest/posttest physical activity questionnaire, pedometer use, weekly goal setting and self-report of step data via the web. The experimental group wore pedometers daily for ten weeks; the control group wore pedometers for one week at baseline and week ten. Average...
Show moreThe purpose of this investigation was to determine the effects of a pedometer-based intervention on physical activity and self-efficacy among community college students in wellness classes (N = 154). The intervention included a pretest/posttest physical activity questionnaire, pedometer use, weekly goal setting and self-report of step data via the web. The experimental group wore pedometers daily for ten weeks; the control group wore pedometers for one week at baseline and week ten. Average weekday physical activity increased 29% for the experimental group and decreased 16% for the control group. Data analysis demonstrated a statistically significant difference due to the treatment regarding step count, differences in mean scores for self-efficacy, and a main effect for treatment for BMI. These results support the effectiveness of pedometer use to increase physical activity and self-efficacy in conjunction with a community college health curriculum.

- Abstract/Description
-
The purpose of the present study was to investigate if any relationship exists between anthropometric measurements with average concentric velocity (ACV) at various intensities in the back squat and the number of repetitions able to be performed during a set to volitional fatigue at 70% of one-repetition maximum (1RM). 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...
Show moreThe purpose of the present study was to investigate if any relationship exists between anthropometric measurements with average concentric velocity (ACV) at various intensities in the back squat and the number of repetitions able to be performed during a set to volitional fatigue at 70% of one-repetition maximum (1RM). 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.

The purpose of this research was to investigate if various psychological wellbeing assessments can predict maximal strength performance and self-scored rating of perceived exertion (RPE) in the back squat. Fifty-eight resistance-trained males and females were recruited, and reported to the laboratory on one day. Subjects completed eight different scales and questionnaires before completing one-repetition maximum (1RM) testing of the squat, followed by two single-repetition sets at 30%, 40%,...

Fifty-eight resistance-trained males and females were recruited, and reported to the laboratory on one day. Subjects completed eight different scales and questionnaires before completing one-repetition maximum (1RM) testing of the squat, followed by two single-repetition sets at 30%, 40%, 50%, 60%, 70%, 80%, and 90% of 1RM, and a set to volitional fatigue at 70% of 1RM. Cognitive anxiety and hypersomnia were found to be positive and negative predictors (p<0.05), respectively, of 1RM performance. Further, self-confidence, grit, and perceived recovery status were significant negative predictors of RPE (p<0.05). Finally, PRS was discovered to be a positive predictor of subject-reported 1RM self-efficacy (b=0.39, t=3.14, p<0.01, R2=0.15).

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.
