Stretching Exercises

This study was conducted to examine the effects of static and dynamic stretching exercises on strength, flexibility, speed and balance in young basketball players. 10 volunteers from the 16 year old male basketball team of Pınar Karsiyaka Sports Club participated in the study. The average age of the athletes is 16 ± 0,0 (year) and the average of the height is 188 ± 0,08 (cm). The study consists of three parts. On the first day, dynamic stretching exercises were performed on the second day and static stretching exercises and performance tests were performed on the third day without performing any exercise. Applied performance tests were hand grip strength, back-leg strength, sit-in flexibility test, 20 m. Sprint test and flamingo balance test. The obtained data were analyzed with the variance analysis (ANOVA test) in the repeated measures using the SPSS 23.0 package program. As a result of the study, the flexibility of the static and dynamic stretching exercises in the data obtained, the difference in the left handed claw strength and the speed of the dynamic stretching exercises were significant (p <0.05). On the other hand, no statistically significant difference was found between static and dynamic stretching exercises and back leg strength and balance (p> 0.05). As a result, it can be said that static and dynamic stretching exercises have a positive effect on flexibility, strength and speed. ÖzetBu çalışma genç basketbolcularda statik ve dinamik germe egzersizlerinin kuvvet, esneklik, sürat ve denge üzerindeki etkisini incelemek amacıyla yapılmıştır.

To investigate acutely the effects of different stretching exercises on football players on the basic motoric properties (strength, flexibility, speed, balance and explosive force). 10 volunteer football players with an average age of 17 participated in the study. Three different measurements protocols were used in the study. The first measurement was performed without stretching exercise, the second measurement was performed after the static stretching exercise and the third measurement was performed after the dynamic stretching exercise. All measurements were carried out at Manisa Tarık Almış sports facilities. To determine the performances of volunteers; back strength, leg strength, hand grip strength, flexibility, 20 m. sprint and flamingo balance test. The Repeated Measures ANOVA test and the Bonferroni Test were used using the SPSS 23.0 package program to analyze the relationship between the performance of the study group and performance tests on different days and different protocols. When the three different methods applied to participants were compared; there is a statistically significant difference between sit and reach, speed and balance tests. As a result, there is a positive effect of stretching exercises on flexibility, sprint and dynamic balance skills. ÖzetFutbolcularda farklı germe egzersizlerinin temel motorik özellikler (kuvvet, esneklik, sürat, denge ve patlayıcı kuvvet) üzerine etkilerini akut olarak incelemektir.

Although warm-up and stretching exercises are routinely performed by gymnasts, it is suggested that stretching immediately prior to an activity might affect negatively the athletic performance. The focus of this investigation was on the acute effect of a protocol, including warm-up and static and dynamic stretching exercises, on speed during vaulting in gymnastics. Eleven boys were asked to perform three different protocols consisting of warm-up, warm-up and static stretching and warm-up and dynamic stretching, on three nonconsecutive days. Each protocol was followed by a “handspring” vault. One-way analysis of variance for repeated-measures showed a significant difference in gymnasts’ speed, following the different protocols. Tukey’s post hoc analysis revealed that gymnasts mean speed during the run of vault was significantly decreased after the application of the static stretching protocol. The findings of the present study indicate the inhibitory role of an acute static stretching in running speed in young gymnasts.

Context: Athletes with intellectual disability (ID) have a high risk of injury while participating in various sports. Warm-up (WU) is the most preventive measure to reduce injuries in sports. Objective: To investigate the effects of dynamic stretching WU (DS-WU) and plyometric WU (PL-WU) on dynamic balance in athletes with ID. Design: Crossover study. Setting: Research laboratory. Participants: A total of 12 athletes with ID (age 24.5 [3.22] y, height 165.7 [8.4] cm, weight 61.5 [7.1] kg, intelligence quotient 61.1 [3.5]). Main Outcome Measures: Dynamic balance was assessed using the Star Excursion Balance Test (SEBT) at pre-WU, post-WU, and 15 minutes post-WU for both the DS-WU and the PL-WU. A 2-way analysis of variance (3 sessions × 2 WU methods) with repeated-measures was used in this study. Results: Following the DS-WU, participants demonstrated significant improvements in the SEBT composite score post-WU (89.12% [5.54%] vs 87.04% [5.35%]; P < .01) and at 15 minutes post-WU (89.55% [5.28%] vs 87.04%, P < .01) compared with pre-WU. However, no significant difference between these two post-WU scores (post-WU and 15 min post-WU) was found. For the PL-WU, participants demonstrated a significant decrease in the SEBT composite score at post-WU (85.95% [5.49%] vs 87.02% [5.73%]; P < .05); however, these scores increased significantly at 15 minutes post-WU (88.60% [5.42%] vs 87.02% [5.49%]; P < .05) compared with that at pre-WU. The SEBT composite scores are significantly higher in the DS-WU than in the PL-WU at both post-WU sessions (P < .05). Conclusion: Both DS-WU and PL-WU could improve dynamic balance and may be recommended as WUs in athletes with ID; however, particular caution should be exercised immediately after the PL-WU.

Given that children with attention deficit hyperactivity disorder (ADHD) are more impulsive than peers, this study explored whether they are correspondingly more creative, and whether creativity declines when impulsivity is decreased through methylphenidate (Ritalin) therapy. A repeated-measures quasi-experimental design was used to compare the performance of 19 boys with previously diagnosed ADHD and 21 comparison boys aged 8 through 11 on two administrations of alternate forms of the Torrance Tests of Creative Thinking-Figural (nonverbal). Boys with ADHD received prescribed methylphenidate only for the first session. Overall, mean Torrance summary scores for comparison boys (mean = 115.1, SD = 16.1) were higher than for boys with ADHD (mean = 107.6, SD = 12.7). However, the difference between means was small (7%) and did not meet the 25% criterion for a clinically significant difference. No changes in performance over time (comparison group) or medication state (ADHD group) were observed. These data suggest that, when measured nonverbally, the creative thinking performance of boys with ADHD is not superior to that of peers who do not have ADHD. Regarding the effects of methylphenidate, prescribed therapy did not influence performance on this measure of creative thinking.

Abstract Background Investigations of β-alanine supplementation shows effects on metabolic (aerobic and anaerobic) participation and performance on swimming by a possible blood acidosis buffering. Considering this background, the objective of the present study was to analyze the effects of β-alanine supplementation on metabolic contribution and performance during 400-m swim. Methods Thirteen competitive swimmers underwent a 6-week, double-blind placebo-controlled study, ingesting 4.8 g.day− 1 of β-alanine or placebo. Before and after the supplementation period, the total anaerobic contribution (TAn) and 30-s all-out tethered swimming effort (30TS) were assessed. Anaerobic alactic (AnAl) and lactic energy (AnLa) was assumed as the fast component of excess post-exercise oxygen consumption and net blood lactate accumulation during exercise (∆[La−]), respectively. Aerobic contribution (Aer) was determined by the difference between total energy demand and TAn. In addition to conventional statistical analysis (Repeated measures ANOVA; p > 0.05), a Bayesian repeated measures ANOVA was used to evidence the effect probability (BFincl). Results No differences and effects were found between groups, indicating no supplementation effects. Repeated measures ANOVA, with confirmation of effect, was indicate reduce in ∆Lactate (p: 0.001; BFincl: 25.02); absolute AnLa (p: 0.002; BFincl: 12.61), fatigue index (p > 0.001; BFincl: 63.25) and total anaerobic participation (p: 0.008; BFincl: 4.89). Conclusions Thus, the results demonstrated that all changes presented were evidenced as a result of exposure to the training period and β-alanine supplementation doesn’t affect metabolic contribution and performance during 400-m freestyle.

Abstract Background: Beta-thalassemia is an inherited disorder of hemoglobin synthesis with many associated morbidities. Osteoporosis is an important cause of morbidity in these patients. Bisphosphonates are potent inhibitors of osteoclast activity and have been recently used for the treatment of osteoporosis in beta-thalassemia. Several studies have indicated that the vitamin D receptor (VDR) gene has a role in the regulation of bone mineral density (BMD) and bone metabolism, but the results are very controversial. The aim of this study is to assess the effectiveness and safety of zoledronic acid in Lebanese thalassemics with osteoporosis. Methods: We studied 23 patients with beta-thalassaemia major (14 patients) and intermedia (9 patients). Thirteen patients were male and 10 were female, with a mean (+/− standard deviation) age of 25 +/− 9 years. All patients had severe osteoporosis and were receiving calcium and vitamin D supplements prior to and during the study. Zoledronic acid was given i.v. at a dose of 4 mg every 3 months over 12 months. The effects were monitored by assessing pain score, analgesic score and performance score. The BMD of the hip and lumbar spine, osteocalcin, bony alkaline phosphatase and pyrrolidine crosslinks were also measured. To gain more insight into the genetic basis of osteoporosis in thalassemia and to correlate this with the response to zoledronic acid, we analysed the polymorphism of the VDR gene in three polymorphic sites (Bsm I, Taq I and Apa I) using restriction enzymes digestion. Results: We have given two doses of zoledronic acid uptil now. The most common adverse event was joint pain in 12 patients (52.2%) lasting for 1–3 days and responding to analgesics. Four patients had perioral numbness and five had fever. These adverse events were markedly reduced after the 2nd dose; only two patients had joint pain. No patients discontinued the study until now. The pain scores, analgesic score and performance score were all improved compared to baseline values. The difference in pain index score was significant (p=0.004), and the reduction in the number of painful sites was slightly significant (p=0.097). There was significant difference in the baseline z score of the spine between transfusion dependent patients (15 patients) and transfusion non-dependent patients (8 patients) (p = 0.042). The distributions of VDR alleles in Bsm I polymorphism were 30.4% for BB, 52.3% for Bb, and 17.3% for bb; in the Apa I polymorphism 17.4% for AA, 47.8% for Aa, and 34.8% for aa; in Taq I polymorphism 30.4% for TT, 52.3% for Tt, and 17.3% for tt. We found no significant differences in baseline BMD between the three groups of Bsm I polymorphism at all sites. Apa I was not associated with significant differences in BMD. The BMD of the Ward’s triangle was higher in patients with the Tt-genotype compared with individuals with the tt-genotype and the difference was almost significant (p=0.089, ANOVA). Conclusions: In Lebanese thalassemics with osteoporosis zoledronic acid (a dose of 4 mg) is well tolerated and the clinical response is quite impressive. However, the response to treatment needs to be assessed by follow-up BMDs and blood bone markers.

BACKGROUND: Various interventions have been recommended to increase ankle dorsiflexion range of motion (DFROM); however, few studies have investigated the long-term effects of applying gastrocnemius stretching with talus-stabilizing taping (GSTST). OBJECTIVE: To compare the effects of gastrocnemius stretching (GS) and GSTST on DFROM and balance in subjects with limited DFROM. METHODS: Twenty-six subjects with limited DFROM were randomly allocated to either the GS group (n= 13) or GSTST group (n= 13) for 6 weeks. Maximum DFROM before heel-off during gait, passive DFROM, posterior talar glide, flexibility of the gastrocnemius, and the lower-quarter Y-balance test (YBT-LQ) were assessed pre-intervention and post-intervention. Two-way repeated-measures analysis of variance was used to compare the changes in variables. RESULTS: The GSTST group had greater maximum DFROM before heel-off, passive DFROM, and posterior talar glide than the GS group. Gastrocnemius flexibility and YBT-LQ scores increased significantly post-intervention in both groups; however, there was no significant difference between the groups. CONCLUSIONS: GSTST is recommend for improving ankle DFROM and balance in subjects with limited DFROM.

Context: Dynamic stretching (DS) is typically suggested during warm-up protocols. Also, foam rolling (FR), which is applied with a foam cylinder, has increased popularity in recent years. However, the combined effects of DS and FR in improving flexibility, dynamic balance, and agility performance are unclear in current literature. Therefore, this study aim to evaluate and compare the acute effects of DS as well as DS followed by FR (DS + FR) on flexibility, dynamic balance, and agility in male soccer players. Design: This study was a crossover study with a within-subject design. Methods: Thirty volunteer male soccer players (mean age 18.80 [0.66] y) were included in the study. Each participant performed the 2 sessions (DS and DS + FR) on separate occasions in a randomized order, with an interval of 72 hours. All sessions were performed in the indoor gym at the sports club. Flexibility was assessed by sit-and-reach test, dynamic balance was assessed by Y balance test, and agility was assessed by t test. Results: Compared with the pretest results, significant improvement in flexibility was observed in both groups (change = 0.55, percentage change = 2.05, effect size [ES] = 0.15, P = .041; change = 0.64, percentage change = 2.36, ES = 0.20, P = .025; respectively). Balance scores did not significantly improve in either group (change = 0.40, percentage change = 0.45, ES = 0.09, P = .342; change = 0.93, percentage change = 1.02, ES = 0.23, P = .103; respectively). Agility performance significantly improved in both groups (change = −0.12, percentage change = −1.18, ES = 0.19, P = .021; change = −0.21, percentage change = −2.18, ES = 0.38, P = .005; respectively). Conclusions: Both DS and DS + FR improved flexibility and agility and did not affect balance. DS + FR was not superior to DS at improving flexibility and agility as compared only with DS. Both methods are effective warm-up protocols to augment factors related to injury risk and performance. It seems that further studies that investigate the combined effects of FR and DS are needed.

Abstract Introduction: Basketball is one of the most popular sports involving gestures and movements that require single-leg based support. Dorsiflexion range of motion (DROM), balance and postural control may influence the performance of this sport. Objective: To compare and correlate measures of balance, postural control and ankle DROM between amateur basketball athletes and non-athletes. Methods: Cross-sectional study, composed by 122 subjects allocated into one control group (CG = 61) and one basketball group (BG = 61). These groups were subdivided into two other groups by age: 12-14 years and 15-18 years. The participants were all tested for postural balance with the Star Excursion Balance Test (SEBT), postural control with the Step-down test and DROM with the Weight-bearing lunge test (WBLT). Between-groups differences were compared using repeated-measures multivariate analysis of variance. Normalized reaching distances were analyzed and correlated with the WBLT and Step-down test. Results: There was no difference in the scores of WBLT (P = .488) and Step-down test (P =. 916) between the groups. Scores for the anterior reach (P = .001) and total score of SEBT (P = .030) were higher in BG. The values for the posterolateral (P = .001) and posteromedial reach (P = .001) of SEBT were higher in BG at the age of 15-18. The correlation between the anterior reach of the SEBT and WBLT was significant in BG between 12-14 years (r = 0.578, P = .008), and in the CG between 15-18 years (r = 0.608, P=.001). Conclusion: The balance was better in the BG, although adolescents between 15-18 years have better balance control for the posteromedial and posterolateral reaches of the SEBT.
