ABSTRACT: Introduction and objectives: Elastic resistance has been commonly used in the therapeutic and fitness setting. However, the effects of a strength training program using elastic resistance exercises to the explosive power and spike speed, which are very important elements for successful volleyball practice, has not been clearly demonstrated. Therefore, the aim of this study was to establish the effects of 8-week Thera-Band training protocols on the development of spike speed, counter movement jump (CMJ) height, peak power and speed of upper limb performance of young female volleyball players. Methods: The participants consists of 20 competitive female volleyball players who regularly train at the same team and aged 15-17 years (age 16.2 ± 0.7 years). All the players were tested for spike speed, CMJ height, peak power and speed of upper limb performances before and after 8-week training program. The players were divided into Thera-Band Training Group (TTG; n=10) and Control Group (CG; n=10). Both groups continued technical and tactical volleyball training together 3 days (120 min.d.-1) a week. Additionally, TTG attended Thera-Band training program through 8-week, 2 days per week and 2 sessions (60 min.d.-1). Results: The findings of the study showed significant change in CMJ height, peak power and spike speed at the end of 8-week. TTG significantly (p ≤ .001) improved CMJ height, peak power and spike speed, whereas the CG showed significant changes only CMJ height and peak power (p ≤ .05) at the end of 8-week. The effect of resistance exercises was significantly higher as compared to the control group (p < .05). Results demonstrated that the TTG players showed greater improvements in CMJ height (d = 1.31, moderate effect size), and spiking speed (d = 2.93, large effect size) performance than CG. Conclusion: It can be concluded that supervised  Thera-Band training contributed development of the performance of spike speed mostly and CMJ height and peak power of lower extremities in young female volleyball players. Due to its effectiveness on muscular performance, the Thera-Band training model can be recommended to the coaches and players in additional to the regular technical training.

The primary objective of this study was to design a digging agility system that was used to analyze the effectiveness of 6 weeks of plyometric training on volleyball players. A total of 24 highly trained college male volleyball players were recruited for this study. The players were equally divided into a plyometric training group and a control group. The agility T-test, peak power output test, 10-meter sprint, and digging agility test were used to examine the effects of plyometric training on the digging agility of volleyball players. One-way analysis of covariance was conducted to examine the differences in the variables between groups. The results reveal that after 6 weeks of plyometric training, the plyometric training group had significant improvements on the agility T-test, digging agility test, and peak power output tests, with statistical power values all greater than 90%. The plyometric training group significantly improved by 2.68% on the agility T-test, 2.35% on the digging agility test, and 7.32% on the peak power output test. The results indicated that appropriate plyometric training can enhance the agility of lateral movements and peak output of vertical jumps, as well as enable players to rapidly complete movements during a moving defense.

Aerobic Interval Training

The effects of a 9-week aerobic interval training program on anaerobic intermittent performance were investigated. Intermittent work consisted of four repeat 30-sec maximal efforts on a cycle ergometer (Wingate test) with 3-min recovery intervals. Thirteen men trained 3 days a week on the cycle ergometer, completing 3-min work-to-rest intervals and progressing from 5 to 10 reps. Relative and absolute values of aerobic power increased significantly for the training group (p <.05). No significant change was observed for the control group (n = 11). The training group demonstrated significant increases in the four anaerobic variables of short-term peak power (SPP), short-term anaerobic capacity (SAC), intermediate-term peak power (IPP), and total work (TW), and across the four 30-sec maximal repeats for anaerobic performance (T1-T4) (p <.05). Greater percentages of increase occurred for IPP and TW, especially during Repeats 3 and 4. The control group only demonstrated a significant increase in SPP for Repeat 3. These data suggest that the type of interval training program used in the study increased aerobic power and also enhanced performance in repeated high intensity, short duration work. Key words: short-term peak power, intermediate-term peak power, total work

AbstractWorking memory (WM) is a fundamental cognitive function that typically declines with age. Previous studies have shown that targeted WM training has the potential to improve WM performance in older adults. In the present study, we investigated whether a multi-domain cognitive training program that was not designed to specifically target WM could improve the behavioral performance and affect the neural activity during WM retrieval in healthy older adults. We assigned healthy older participants (70–78 years old) from a local community into a training group who completed a 3-month multi-domain cognitive training and a control group who only attended health education lectures during the same period. Behavioral and electroencephalography (EEG) data were recorded from participants while performing an untrained delayed match or non-match to category task and a control task at a pre-training baseline session and a post-training follow-up session. Behaviorally, we found that participants in the training group showed a trend toward greater WM performance gains than participants in the control group. Event-related potential (ERP) results suggest that the task-related modulation of P3 during WM retrieval was significantly enhanced at the follow-up session compared with the baseline session, and importantly, this enhancement of P3 modulation was only significant in the training group. Furthermore, no training-related effects were observed for the P2 or N2 component during WM retrieval. These results suggest that the multi-domain cognitive training program that was not designed to specifically target WM is a promising approach to improve WM performance in older adults, and that training-related gains in performance are likely mediated by an enhanced modulation of P3 which might reflect the process of WM updating.

The Difference

To observe the difference in clinical effects of scalp-point cluster acupuncture combined with rehabilitation training in treating spastic paralysis of upper limbs after stroke. Using a randomized controlled design, 96 patients with upper limb spastic paralysis after stroke were randomly divided into two groups: treatment group (scalp acupuncture plus rehabilitation training group 48 cases), control group (rehabilitation training group 48 cases). After 2 courses of treatment, it was judged by observing clinical efficacy evaluation, Ashworth classification, and Fugl-Meyer (FMA) score. The total effective rate was 91.7% in the treatment group and 68.7% in the control group; the difference between the two groups was statistically significant (P <0.05). Before treatment, the difference in Ashworth classification between the two groups was not statistically significant (P> 0.05); after treatment, the difference between the two groups was statistically significant (P <0.01). After treatment, the difference between the two groups was statistically significant (P＜0.05). The Fugl-Meyer (FMA) scores of the two groups of patients before treatment were comparable (P>0.05), and there were significant differences between the two groups after treatment (P <0.05). The difference of Fugl-Meyer (FMA) scores between the two groups was statistically significant (P < 0.01). Scalp cluster acupuncture therapy is more effective than traditional acupuncture therapy alone in treating vertebral artery type cervical spondylosis. Scalp cluster acupuncture combined with Bobath technique is effective in treating spastic paralysis of upper limbs after stroke, and it is worthy of clinical application.

Introduction: The mTOR pathway in skeletal muscle plays a very important role in the protein synthesis process, which plays a very important role in proteins. The role of endurance exercise has not yet been studied in this important pathway in protein synthesis in people with type 2 diabetes. The purpose of the present study was to investigate the effect of 8 weeks endurance training on the content of total and phosphorylated AKT1, mTOR, P70S6K1 and 4E-BP1 in skeletal muscle FHL of rats with type 2 diabetes. Methods: In this experimental study, 16 Sprague-Dawely male rats with average weight of 270±20 were selected and randomly divided into two groups: control (n=8) and endurance training (n=8). The training group exercised according to the training program 4 days a week for 8 weeks. While the control group had no training program. T-test and SPSS V-19 were used to analyze the data. Results: There was not observed any significant difference in the content of total (P=0.58) and phosphorylated (P=0.33) AKT1, total (P=0.47) and phosphorylated (P=0.78) mTOR, total (P=0.24) and phosphorylated (P=0.12) P70S6K1 and total (P=0.45) and phosphorylated (P=0.48) 4E-BP1 proteins in the endurance training group compared to the control group. Conclusion: Endurance training for 8 weeks could not increase the total and phosphorylated content proteins of the present study; therefore, it cannot lead to protein synthesis or muscle hypertrophy through mTORC1 pathway.

This study examined the effects of a short-duration supplementary strength–power training program on neuromuscular performance and sport-specific skills in adolescent athletes. Twenty-three female “Gymnastics for All” athletes, aged 13 ± 2 years, were divided into a training group (TG, n = 12) and a control group (CG, n = 11). Both groups underwent a test battery before and after 10 weeks of intervention. TG completed, in addition to gymnastics training, a supplementary 7–9 min program that included two rounds of strength and power exercises for arms, torso, and legs, executed in a circuit fashion with 1 min rest between rounds, three times per week. Initially, six exercises were performed (15 s work–15 s rest), while the number of exercises was decreased to four and the duration of each exercise was increased to 30 s (30 s rest) after the fifth week. TG improved countermovement jump performance with one leg (11.5% ± 10.4%, p = 0.002) and two legs (8.2% ± 8.8%, p = 0.004), drop jump performance (14.4% ± 12.6%, p = 0.038), single-leg jumping agility (13.6% ± 5.2%, p = 0.001), and sport-specific performance (8.8% ± 7.4%, p = 0.004), but not 10 m sprint performance (2.4% ± 6.6%, p = 0.709). No change was observed in the CG (p = 0.41 to 0.97). The results of this study indicated that this supplementary strength–power program performed for 7–9 min improves neuromuscular and sport-specific performance after 10 weeks of training.

Summary Study aim: The purpose of this study was to examine the effects of a repeated sprint training program in addition to volleyball training on the aerobic capacity of college volleyball players. Materials and methods: Eighteen male volleyball players were randomly assigned to either an experimental group (n = 9, age: 21.2 ± 1.3 years) or a control (n = 9, age: 21.2 ± 1.6 years) group. Both groups followed a traditional volleyball training program three times per week for 6 weeks. The experimental group additionally performed a repeated sprint training protocol immediately before each volleyball training session. The repeated sprint training consisted of 1-3 sets of 5 × 20 m maximal sprints with 20 seconds of active recovery between sprints and 4 min of passive recovery between sets. Before and after the 6-week training period, all participants performed an incremental treadmill test to determine maximal oxygen uptake (VO2max) and time to exhaustion, and the repeated sprint test (10 × 20 m with a 20‑second recovery between each sprint).Results: The experimental group showed significant improvements in VO2max (+7.1 ± 4.8%; p = 0.001) and running time to exhaustion (+15.8 ± 6.8%; p = 0.004) after training. The best 20-m sprint time (−2.3 ± 2.5%; p = 0.029), mean sprint time (−5.3 ± 3.1%; p = 0.001) and fatigue index (−34.1 ± 28.2%; p = 0.012) also improved significantly in the experimental group. None of these variables changed significantly in the control group (p > 0.05).Conclusions: The current findings indicate that the addition of a repeated sprint training program can improve both the aerobic capacity and anaerobic performance of college volleyball players.

AbstractThis study investigated the effectiveness of a specialized strength training program on maximal handgrip strength in young wrestlers. 72 young wrestlers (36 children: 8–10 years-old and 36 adolescents:13–15 years-old) participated in the present study. Both age-categories were assigned into a training group (18 children and 18 adolescents) and a control group (18 children and 18 adolescents). The training groups, in conjunction with the wrestling training performed a 4-month (2 sessions/week) specialized handgrip training program. Maximal handgrip strength was evaluated pre, at the intermediate (2 months) and at the completion of the program (4 months). Maximal handgrip strength values increased during the intermediate and post-training measurements compared to pre-training measurement in training and control groups (p<0.001). No significant differences were observed on pre-training and intermediate measurements between groups, while significant differences were observed during the post-training measurement. Training group exhibited significantly (p<0.01) greater maximal handgrip strength values than the control group irrespective of age-category and hand-preference. A 4-month handgrip strength training program, incorporated into the conventional wrestling training, provokes greater adaptations in maximal handgrip strength than the wrestling training per se. For greater handgrip training adaptations are required more than 14 specialized handgrip training-sessions.

Objective: To determine the feasibility of dual task training in persons with Multiple Sclerosis. Design: Randomized, single-blinded controlled trial. Setting: University research laboratory. Participants: A total of 234 individuals inquired about the investigation. After screening, 20 individuals with multiple sclerosis who self-reported problems with multitasking and were ambulatory volunteered for the investigation. 14 participants completed the post-assessment following the 12-week intervention. Intervention: Participants were randomly assigned to either single task training program which focused on balance and walking function ( n=6) or dual task training program that incorporated cognitive tasks in balance and walking training ( n=8). Measures: Before and after the 12-week interventions participants underwent assessments of walking; dual task walking; balance (Berg Balance Scale and balance confidence) and cognition as indexed by the Brief International Cognitive Assessment for MS. Results: There was an 8.5% recruitment rate, a 70% retention rate, and a 100% adherence rate. There was a trend for dual task gait speed to improve in the dual task training group following the intervention (Pre: task 1: 109.8±39, task 2: 104.2±34.1; Post: task 1:127.6±40.1, task 2: 122.8±37.4; P=0.14; η2 = 0.24). There was also a trend for the dual task training group (28.1) to have greater performance than the control group (24.7) on visuospatial memory ( P=0.10; η2= 0.23). There were no changes in cognitive performance during walking trials. Conclusions: The study procedures were found to be feasible and improvements should be made in recruitment efforts going forward. Further examination of dual task training programs in individuals with multiple sclerosis is warranted.
