Book Description
"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

Book Description
PURPOSE: Previous studies have examined the relationship lower-body strength and power has with performance in events that require change of direction (COD). However, there is a scarcity of investigations which have considered the influence strength and power have on the magnitude of improvement in COD performance as a result of training. Moreover, interventions selected within the literature are often not representative of interventions used by strength and conditioning professionals. Therefore, the purpose of this study was to investigate the relationship between strength and power and the magnitude of improvement in COD as a result of training. METHODS: Eleven collegiate athletes (age = 20.55 ± 1.214 yr; height = 186.52 ± 6.569 cm; mass = 108.76 ± 17.433 kg) from a Division II American football program participated in the study. Subjects were pre and posttested in vertical jump (VJ), standing broad jump (SBJ), peak force (PF), time to peak force (TPF), rate of force development (RFD), one-repetition maximum back squat (1-RM BS), hexagon test, pro agility test, and T -test. Both absolute values along with data normalized to body mass were used for purposes of comparison. Subjects participated in an 8 week training program designed to increase strength, power, and COD. Tests used to assess COD during pre and posttesting were not used during the intervention. RESULTS: Pretest VJ power showed strong correlation with both absolute change and percent improvement in the T-test (r = -0.59 · and -0.58, respectively). A strong correlation was also found between the absolute change in SBl and the absolute change in the hexagon test (r = -0.51). Pretest ReI PF showed strong correlation with both pro-agility and the T -test (r = -0.5 and -0.58, respectively). Pretest TPF and the hexagon test showed strong correlation (r = -0.S1) as did ReI 1-RM BS and the T-test (r = -0.54). Poshest ReI PF revealed strong association with both the pro agility test and the T-test (r = -0.61 and -0.81, respectively) and Rel 1-RM BS showed strong correlation with performance in the T -test (r = -0.6). CONCLUSION: The findings of this investigation suggest that an athlete's ability to express strength and power may influence subsequent adaptation to interventions designed to improve COD. Moreover, adaptations in strength and power may also influence the magnitude of Improvement in COD tasks. PRACTICAL APPLICATION: Practitioners may wish to consider sequencing their training to focus on strength and power early in the athlete development process in order to enhance potential adaptations in COD later on in training. In addition, when considering the addition of COD to the training plan, it may be appropriate to maintain focus on increasing strength and power. Key words: COD, power, isometric strength, dynamic strength, American football.
