“…This is also evident in the golf swing 18 and it is possible that increased leg power, as inferred by jumping assessment, aids rapid RFD, 19 influencing CHS (Read et al, 2013). 20 The study demonstrated that following eight weeks of plyometric training, the intervention group 21 significantly increased their physical performance in the SVJ, SBJ, and KRT, when compared to the 22 control group (10.8%, 10.2%, 22.9%, respectively). The control group however, also displayed 23 significant differences (3.0%, 3.2%, 3.5% respectively) between pre and post-tests in these variables, 24 but this is likely explained by the typical error of these assessment methods.…”

The purpose of this study was to determine the effects of an eight-week plyometric training 2 intervention on measures of golf swing performance in highly skilled, adolescent golfers. Sixteen 3 male golfers were recruited to this study, being placed into two handicap and age-matched groups: 4 intervention and control. The intervention group completed an eight-week plyometric training 5 programme in addition to their golf-specific practice to study effects on clubhead speed (CHS), ball 6 carry distance (BCD) and other associated measures. The control group continued to undertake their 7 golf-specific training with no plyometric training. The intervention group demonstrated significant 8 (p<0.05) improvements in CHS and BCD between pre and post trials. The control group showed no 9 significant (p>0.05) changes in golf performance. The results suggest that in highly skilled adolescent 10 golfers, eight-weeks of plyometric training may help to improve CHS and BCD by approximately 3%. 11However, large between participant performance differences were observed after the training 12 intervention. It was concluded that, for golfers wishing to improve their CHS and BCD, a golf-specific, 13 plyometric training programme could play an important part in the athlete's training programme. 14 KEY WORDS 15Clubhead speed, ball carry distance, handicap, teenage athletes, adolescents, training.

“…The best score (highest: CMJ, SJ, MBT, 6 s Cycle, lowest: RMS) was used for data analysis, as this has shown to significantly increase intersession reliability as opposed to means [22]. Changes were assessed across all conditions using a repeated measures ANOVA through SPSS for Windows, release 22.0 (SPSS, IBM Corporation, Armonk, NY, USA).…”

The purpose of the study was to investigate the acute effects of two different quantities of branched-chain amino acids (BCAA) on the recovery of muscle function following high-intensity resistance training in trained individuals. Five resistance-trained males were recruited and performed baseline assessments of, countermovement (CMJ) and squat jump (SJ), peak (PP) and mean (MP) power (6s Cycle Sprint) and perceived muscle soreness (RMS). In a counterbalanced, single-blind fashion, participants were provided with either, placebo or 6 g or 18 g BCAA 20 min prior to, and immediately after completion of a high-intensity strength session (ST). At 24 h post ST, all assessments were completed under all three experimental conditions. Following ST, there were significant decrements in all measures of muscle function across conditions when compared to baseline values (P<0.05). However, ingestion of 6 g and 18 g BCAA was shown to significantly attenuate these decrements in comparison to placebo (P<0.05). A dose-response for BCAA was also present as significant differences (P<0.05) were shown between ingestion of 6 g and 18 g; CMJ (18 g: 59

Post-activation potentiation following different modes of exercise, R-31239, Revision 1Post-activation potentiation following exercise 3 ABSTRACTThe performance characteristics of skeletal muscle are transient in nature and have been shown to be significantly affected by its contractile history, where the phenomenon of acute enhancement is termed post-activation potentiation (PAP). Acute enhancement of dynamic activity has been observed when preceded by resistance exercises, however little information exists for plyometric activity as a conditioning stimulus. In addition, no study has examined PAP effects on more than one subsequent performance trial. The purpose of the present study was to determine whether countermovement jump (CMJ) performance could be enhanced if preceded by heavy resistance exercise or by dynamic plyometric activity over three trials.Thirteen anaerobically trained male subjects (mean ± SD: age, 22 ± 3 years; height, 182.4 ± 4.3 cm; body mass, 82.7 ± 9.2 kg) performed in a counterbalanced order 3 half squats using a 3 repetition maximum loading (SQUAT), a set of 24 contacts of lower body plyometric exercises (PLYO), or a control of no activity (REST) 5 min prior to each CMJ. Three sets of each treatment and CMJ were performed in total and maximal displacement (dmax), peak power (Ppeak) and peak vertical force (Fpeak) were recorded, while rate of force development (RFD) and relative force (F / body mass) were calculated for every trial. No significant differences were revealed for any of the other variables, but greater displacement was found for SQUAT compared to REST or PLYO, while no differences were revealed for any of the conditions for the repeated trials. Although heavy resistance-induced PAP seems to enhance jump height compared to REST or PLYO in repeated CMJ performance, it has no additional benef...
