The effects of high and low repetition daily undulating periodization models with equated volume on strength and hypertrophy in trained males
Title
The effects of high and low repetition daily undulating periodization models with equated volume on strength and hypertrophy in trained males.

Abstract/Description
Periodized training programs seem to augment muscle performance (i.e., hypertrophy, strength and muscle endurance), however, optimal repetition ranges to achieve these adaptations are unclear. Thus, the purpose was to compare high and low repetition daily undulating periodization (DUP) models, with equal volume on performance. Eleven trained, college-aged males were counterbalanced into high (DUPHR) or low (DUP-LR) repetition groups. Subjects performed the squat and bench press 3X/wk. for...
Show morePeriodized training programs seem to augment muscle performance (i.e., hypertrophy, strength and muscle endurance), however, optimal repetition ranges to achieve these adaptations are unclear. Thus, the purpose was to compare high and low repetition daily undulating periodization (DUP) models, with equal volume on performance. Eleven trained, college-aged males were counterbalanced into high (DUPHR) or low (DUP-LR) repetition groups. Subjects performed the squat and bench press 3X/wk. for 8wks. Outcome measures included one-repetition maximum (1RM) bench press, squat, and total strength (TS=squat+bench press), and muscle thickness (MT). 1RM strength increased with no difference between groups. Both groups increased total chest and total body MT (p<0.05); but only DUP-HR increased thigh MT (p<0.05). Effect sizes showed meaningful differences in strength favoring DUP-LR for bench press-1.48 and TS-0.89. Our findings indicate with equal volume, there may be meaningful differences in strength that are repetition-dependent, and varying responses to MT across different muscle groups.

Effects of GravitronRTM training on upper body strength in 11--13 year old students
Title
Effects of GravitronRTM training on upper body strength in 11--13 year old students.
Creator
Howard, Nancy Joanne., Florida Atlantic University, Torok, Don
Abstract/Description
This study examined the effects of using one or three sets of assisted pull-ups on the GravitronRTM 2000 AT unit by StairMaster RTM to increase upper body strength in adolescents. Fifty-four students participated in the study consisting of three upper body strength tests: pull-ups, flexed-arm hang, and push-ups. Forty-two subjects engaged in a 12-week training protocol on the GravitronRTM performing either one set (T1, N = 21), or 3 sets (T3, N = 21). Statistical analysis supported a...

Fifty-four students participated in the study consisting of three upper body strength tests: pull-ups, flexed-arm hang, and push-ups. Forty-two subjects engaged in a 12-week training protocol on the GravitronRTM performing either one set (T1, N = 21), or 3 sets (T3, N = 21). Statistical analysis supported a significant improvement in strength (p < 0.05) as assessed by the number of pull-ups completed for the T3 group. All other test results revealed nonsignificant changes. This type of training did not significantly increase the passing rate on the President's Council on Physical Fitness and Sports standards for strength or endurance. In conclusion, upper body strength was improved with 3 sets of assisted pull-up training after 12 weeks of training as shown by an increase in number of pull-ups performed.

The influence of time-equated training programs on muscle hypertrophy, strength, and body composition
Title
The influence of time-equated training programs on muscle hypertrophy, strength, and body composition.
Creator
Dolan, Chad, Zourdos, Michael C., Florida Atlantic University, College of Education, Department of Exercise Science and Health Promotion
Abstract/Description
The purpose of this study was to determine if barbell circuit training (RTC) as a model for concurrent training is superior to high intensity interval (CTHI) or moderate intensity continuous (CTMI) cycling for changes in muscular strength, hypertrophy, and body composition. Eleven trained males were recruited and counterbalanced into three groups. Each program featured three alternating days of resistance training per week, with one of the above time-equated (30-minute) concurrent training...

Eleven trained males were recruited and counterbalanced into three groups. Each program featured three alternating days of resistance training per week, with one of the above time-equated (30-minute) concurrent training modalities between sessions. All groups increased muscular strength (p<0.05, RTC=7.48%, CTHI=10.32%, CTMI=15.74%) with no group differences (p>0.05). Increases in upper body muscle hypertrophy were similar in RTC and CTMI (p<0.01, RTC=20.18%, CTMI=20.97%), increases in lower body muscle hypertrophy only occurred in CTMI (VM: p=0.01, 38.59%, VLP: p=0.07, 13.33%), while no hypertrophy changes were detected in CTHI (p>0.05), no group experienced changes in body composition (p>0.05). These findings suggest similar muscle performance benefits from barbell circuit or cycling concurrent training.

Relationship Between Anthropometric Measurements and Average Concentric Velocity In The Back Squat
Title
Relationship Between Anthropometric Measurements and Average Concentric Velocity In The Back Squat.
Creator
Cooke, Daniel M., Zourdos, Michael C., Florida Atlantic University, College of Education, Department of Exercise Science and Health Promotion
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.
