"The use of variable resistance in weight training is suggested to improve muscular strength and power. Variable resistance training using rubber bands and chains in a ballistic fashion has emerged as a possible means of increasing muscular strength and power. This advanced training approach is intended to limit the deceleration period in traditional bench press and squat, and facilitate improved neuromuscular response to training. Subjects (n=19) from Bemidji State University's Division II women's soccer and volleyball teams were assigned into two workout programs. These programs utilized either variable resistance training (bands/chains) or traditional methods. Sessions were conducted for duration of eleven weeks. Pre, mid, and post testing was conducted for data collection. There were no significant interaction or main effect between the two groups in average upper body power (AUP) and peak upper body power (PUP) and time p>.05. Average lower body power (ALP) and peak lower body power (PLP) showed no significant interaction between groups p>.05 however a significant main effect of time was found for both ALP p.001 and PLP p.001. There was no significant effect of group found for either MS (p.55) or MB (p.75). A significant main effect on time was also found for the maximal squat (MS) test and maximal bench press (MB) test showing p

ABSTRACT: The bilateral deficit (BD) is a well-established phenomenon describing the difference in force capabilities between bilateral and unilateral movements. The majority of research has used seated machine-based protocols to measure the BD and deduce training implications. However, these are uncommon in modern strength training practices and do not reflect the movement patterns found in sport. The purpose of this study was to use a ground-based multi-joint exercise to determine if a BD was present in trained athletes. Forty trained NCAA Division III football players (20.9 + 0.8 years, 209.7 + 30.1 lb., 71.2 + 2.2 in) completed a bilateral and unilateral 1RM deadlift. Participants were divided into two groups to ensure that fatigue and the order of the 1RM tests did not have any effect. Group A (n = 17) completed the bilateral 1RM deadlift first, Group B (n = 23) completed the unilateral 1RM deadlift first. The remaining test was performed 48-72 hours later to provide adequate rest. Unilateral 1RM values were multiplied by two and compared to the participants’ bilateral 1RM. A significant bilateral deficit was present in both groups (M = 102.5). Participants were significantly stronger on one leg, relatively. Despite perceptions about bilateral facilitation, experienced athletes with a balanced training history appear to experience a BD and possess the capacity to be stronger on one leg. These findings suggest that trained athletes may benefit from unilateral training for the development of strength.

Book Description
Previous studies with college athletes determined that the shoulder girdle plays a vital role in a variety of athletic activities. The previous research showed that a decrease in shoulder range of motion (ROM) was associated with a higher risk injury. Decreased shoulder ROM was shown to be a primary reason that many athletes were unable to perform many overhead lifting variations within their strength and conditioning programs. The purpose of this research was to evaluate a group of athletes by means of a postural assessment using the overhead squat test. This study consisted of a pretest-post test control group design. The dependent variable that was observed was the goniometric measurement of the shoulder ROM in response to the independent variable, which was a specialized upper body stretching protocol. Current NCAA Division I male athletes from a university in the south, who competed in a variety of different intercollegiate sports, volunteered for this study (N = 27). For the purpose of the current study the athlete was asked to perform three trials of the overhead squat test. For each of the trials goniometric data were collected. After the data were collected the athletes were taught the joint-specific stretching protocol that was to be used as the intervention for this study. When the pretest and posttest data were observed, the intervention group had an average decrease of 14.7 degrees over the course of the study, while the control group only showed an average decrease of 1.6 degrees. A one-way ANOVA showed that the means of the two groups were not statistically different at the posttest but were significantly different at the pretest. To check the interaction between the grouping factor and the trial factor, a 2 x 2 ANOVA, at a p-value of 0.05, was used to determine the between measurement interactions. From the data that were collected it was determined that there was a statistically significant time factor as well as interaction effect when comparing the two conditions.

ABSTRACT: The purpose of the current study was to examine the relationship between aerobic power and repeated sprint ability. Division III collegiate football players (n = 30) participated in the study. On the first day of testing, each subject completed the Yo Yo Intermittent Recovery Test Level 2 (YYI2). On the second day of testing, each subject completed a repeated sprint test using football specific work to rest ratios that included two rounds of 6 sprints. No significant relationship was found between end stage completed in the YYI2 and percent decrement in round one, round two, or total (p > .05). Two main limitations were identified in the study. The first was that the difficulty level of the YYI2 for the subjects was too high. The second was the lack of concealing from the subjects the number of total sprints that would be completed. While no significant relationship was found, practical implications could be useful for strength and conditioning coaches involved in the physical preparation of collegiate football players.

ABSTRACT: Velocity based training: Ballistic Power Training versus Hang Cleans on Power Output and Acceleration. Purpose: The study examined whether a difference was seen in performing a hang clean or a ballistic power exercise (Barbell jump squat) on power output over a 4 week period. Methods: A true experimental design study, which lasted for five weeks including a week of familiarization. The subjects will be Division III collegiate athletes (N = 19) between the ages of 18-21 from Massachusetts. Subjects are split into two groups, a hang clean group and a jump squat group. The jump squat group had speeds measured by a linear position transducer and was between 1.3-1.4m/s. Countermovement jump height and 20m sprint speed was measured pre- and posttest. Results: No significant interaction was found between exercise type on CMJ height between pre- and posttest. As hypothesized, no significant mean difference was seen in CMJ between Squat Jump and Hang Clean. No significant mean difference was found between pre- and posttest for sprint times. No significant interaction was seen on sprint times in exercise type on sprint times from pretest to posttest. No significant mean difference was found between pre- and posttest for time. No significant mean difference was found between hang clean and squat jump on 20m sprint times. Conclusion: Both groups had meaningful improvements in jump height and acceleration. Despite the improvements, there were no differences between both groups on jump height and acceleration.

Abstract: The investigation was designed to determine the effects of eccentric overload training on measures of strength and power when compared with standard methods of squat training. Division III female collegiate athletes (age: 19.71 ± 1.74 years, height: 63.49 ± 5.28 in.) were matched according to 1-RM squat strength and randomly assigned to the eccentric overload training group or the standard squat training group. The squat was performed twice a week over 4 weeks. Squat strength improved significantly (p
