The Difference

Context:Overreaching can be beneficial, but there is a risk of overtraining.Objective:To investigate the difference in sleep efficiency between overreached and nonover-reached swimmers.Design:Repeated-measures, between-subjects. Swimmers were determined to be overreaching if 2 or more of their consecutive weekly swim times increased by 5% or more from baseline.Participants:9 competitive high school and university sprinter swimmers.Intervention:24-h wrist actigraph.Main Outcome Measure:Sleep efficiency as measured by the actigraph.Results:There was a significant difference in sleep efficiency on night 1 between the overreached and nonoverreached swimmers (P = .008), as well as in their times after averaging over all 5 trials and adjusting for baseline (P = .016). By the fourth swim trial, the overreached swimmers had significantly slower swim times than those of the nonoverreached swimmers (P = .001).Conclusions:Sleep efficiency shows potential as an objective, noninvasive predictor and monitor of overreaching in swimmers.

Context:Some researchers have suggested that an alteration of stretch perception could be responsible for the success of the contract-relax (CR) stretch, a stretch technique derived from proprioceptive neuromuscular facilitation (PNF).Objective:This study was conducted to determine if the alteration of the stretch perception is a possible explanation for the range of motion (ROM) gains of the CR stretch.Participants:Eighteen subjects performed two stretches in randomized order: the slow stretch and the CR stretch.Main Outcome Measure:The stretch intensity was controlled. The stretch force was measured and compared between the slow stretch and CR stretch.Results:There was a significant difference between the stretch force that could be applied in the PNF stretch (126.0 N) and the slow stretch (108.4 N); P = 0.00086. The average stretch tolerance progressively increased with successive trials from 120.6 N in the first trial to 132.4 N in the fourth trial.Conclusion:The alteration of stretch perception plays a role in the success of the CR form of PNF stretching. At least four repetitions of the CR stretch are recommended to get the greatest ROM gain.

Objective:To assess the efficacy of lidocaine iontophoresis on myofascial trigger-point pain.Setting:University athletic training facility.Design:Randomized, double-blind, placebo-controlled, repeated-measures.Subjects:Twenty-three subjects with sensitive trigger points over the trapezius.Intervention:Placebo iontophoresis treatment without current or lidocaine, control treatment using distilled water and normal current dose, medicated treatment using 1% lidocaine and normal current dose.Main Outcome Measure:Trigger-point pressure threshold assessed with an algometer.Results:ANOVA revealed a significant difference among treatments (F2,40= 7.38,P< .01). Post hoc comparisons revealed a significant difference in pressure threshold between the lidocaine treatment and the control (P= .01) and placebo (P= .001) treatments. Effect sizes of .28 and .39, respectively, were found for these comparisons.Conclusions:Although the data revealed significant differences between treatments, the small effect sizes and magnitude of the pressure-sensitivity deviation scores suggest that iontophoresis with 1% lidocaine is ineffective in treating trigger points.

Context:Many athletes report that foam rollers help release tension in their muscles, thus resulting in greater range of motion (ROM) when used before stretching. To date, no investigators have examined foam rollers and static stretching.Objective:To determine if foam rolling before static stretching produces a significant change in passive hip-flexion ROM.Design:Controlled laboratory study.Setting:Research laboratory.Participants:40 subjects with less than 90° of passive hip-flexion ROM and no lower-extremity injury in the 6 mo before data collection.Interventions:During each of 6 sessions, subjects' passive hip-flexion ROM was measured before and immediately after static stretching, foam rolling and static stretching, foam rolling, or nothing (control). To minimize accessory movement of the hip and contralateral leg, subjects lay supine with a strap placed across their hip and another strap located over the uninvolved leg just superior to the patella. A bubble inclinometer was then aligned on the thigh of the involved leg, with which subjects then performed hip flexion.Main Outcome Measure:Change in passive hip-flexion ROM from the preintervention measure on day 1 to the postintervention measure on day 6.Results:There was a significant change in passive hip-flexion ROM regardless of treatment (F3,17 = 8.06, P = .001). Subjects receiving foam roll and static stretch had a greater change in passive hip-flexion ROM compared with the static-stretch (P = .04), foam-rolling (P = .006), and control (P = .001) groups.Conclusions:Our results support the use of a foam roller in combination with a static-stretching protocol. If time allows and maximal gains in hip-flexion ROM are desired, foam rolling the hamstrings muscle group before static stretching would be appropriate in noninjured subjects who have less than 90° of hamstring ROM.

Rowers’ anthropometric characteristics and flexibility are fundamental to increase stroke amplitude and optimize power transfer. The aim of the present study was to analyze the effect of foam rolling and static stretching on the range of motion over time. Eight university rowers (24.8 ± 3.4 yrs., height 182.3 ± 6.5 cm, body mass 79.3 ± 4.6 kg) participated in an alternating treatment design study with two-way repeated measures ANOVA. The sit and reach test was used to measure the range of motion. Both in the foam rolling and in the static stretching method, a pre-test (T0), a post-test (T1), and a post-15-min test (T2) were performed. A significant effect was observed on the range of motion over time (p < 0.001), but not for time x method interaction (p = 0.680). Significant differences were found between T0 and T1 with foam rolling and static stretching (p < 0.001, d = 0.4); p < 0.001, d = 0.6). The differences between T0 and T2 were also significant with both methods (p = 0.001, d = 0.4; p < 0.001, d = 0.4). However, no significant difference was observed between T1 and T2 (p = 1.000, d = 0.1; p = 0.089, d = 0.2). Foam roller and static stretching seem to be effective methods to improve the range of motion but there seems to be no differences between them.

The different effects of intermittent and continuous stretching on the mechanical properties of the musculotendinous complex have been unclear. This study aimed to compare the effects of intermittent and continuous stretching for the same duration on the range of motion (ROM), passive resistive torque (PRT), and musculotendinous stiffness (MTS) of ankle plantar flexors. Eighteen healthy young men participated in the study. Intermittent (four sets × 30 s) and continuous stretching (one set × 120 s) were performed in random orders on two separate days. Both stretching protocols were conducted using a dynamometer with a constant torque applied. ROM and PRT were determined using a dynamometer, and MTS was calculated using the torque–angle relationship measured before and after stretching. Two-way repeated measures analysis of variance was performed for all parameters. Both intermittent and continuous stretching significantly increased ROM and decreased PRT and MTS (p < 0.05). Intermittent stretching led to greater changes in ROM and PRT than continuous stretching. However, the reduction in MTS did not differ between the two conditions. These results suggest that intermittent stretching is more effective in increasing ROM and changing the mechanical properties of the musculotendinous complex.

Mindfulness meditation has frequently used sound and music as an important component. However, research on effective music stimuli is scarce. After a series of studies evaluating the most effective, useful, and preferred auditory stimuli, we were interested in exploring whether these effective musical features were transferred to new music. In this study, we evaluate our original music stimuli with three new stimuli composed under similar principles. Non-musician and musician participants ( N = 114) in a multisite study evaluated their mindfulness state after listening to four music stimuli, and rated their usefulness and preference. Results from a repeated-measures analysis of variance (ANOVA) at each site indicated no significant difference in mindfulness effectiveness. Friedman’s ANOVAs for the usefulness of the music stimuli showed similar non-significant results in both sites. A mixed model among sites did not show significant differences among groups. Preference rankings were not significantly different for non-musicians, but musicians did show a statistically significant preference of the Original stimuli over Stimulus 2, probably due to sound quality. These results indicate the feasibility of transferring previously researched and effective musical features to new stimuli. Identifying the effective “active ingredients” of music interventions may be one way of supporting evidence-based practice in music therapy.

Equine Chorionic Gonadotropin

This study was carried out using 80 multiparous Awassi ewes during breeding season to compare the effects of controlled internal drug release (CIDR) withdrawal time on ewe fertility. Ewes were equally and randomly allotted into 4 groups (n = 20/group). Ewes had a CIDR inserted for 3, 6, 9, or 12 days with intramuscular administration of 300 IU of equine chorionic gonadotropin (eCG) at withdrawal time. Oestrus was detected using vasectomized ram starting 12 h after CIDR withdrawal and repeated every 12 h up to 84 h. Blood samples were collected from all groups at the time of CIDR withdrawal for measuring of oestradiol (E2) and progesterone (P4) serum concentrations using commercial ELISA kits and micro-titrimetric plates. Timed insemination was performed 48 h post CIDR withdrawal in all groups. Pregnancy was diagnosed by ultrasonography at day 23 post-insemination and confirmed at day 35. Comparisons among groups were evaluated using Chi Square (χ2) test in all measured parameters except hormones levels, which analysed by repeated-measures analysis of variance (ANOVA), using SAS (SAS Institute Inc., Cary, NC, USA). A difference was considered significant at P < 0.05 level. The results revealed that the retention, vaginal discharge and drawstring breakage rates after CIDR removal were insignificantly differed between all groups. On the other hand, pregnancy rate was significantly (P ≤ 0.05) higher in 9-d and 6-d groups (68.4 and 60%, respectively) than the 3-d group. While, no significant difference was detected between 12d group and other groups. The heat detection rate was significantly (P ≤ 0.05) higher in 12d group (100%) than 6-d and 3-d groups (80 and 45%, respectively). While, no significant difference was detected between 12-d and 9-d groups in heat detection rate. P4 was significantly higher in the 12-d group (13.4 ± 3.06 ng mL−1) than other groups. While E2 was significantly lower in the 12-d group (1.6 ± 0.06 pg mL−1) than other groups. These results indicated that withdrawal of CIDR devices after 9 days are efficient in synchronizing oestrus in ewes and provided higher pregnancy rate.

Abstract The aim of this study was to examine the effects of twelve weeks of resistance training with different exercise orders (upper limbs and lower limbs vs. lower limbs and upper limbs) on flexibility levels in elite judo athletes. Thirtynine male athletes were randomly divided into 3 groups as follows: G1 (n = 13), G2 (n = 13), and CG (n = 13). The flexibility was assessed on 8 joint movements: shoulder flexion and shoulder extension, shoulder abduction and shoulder adduction, trunk flexion and trunk extension, and hip flexion and hip extension. Two-way repeated measures ANOVAs (time [pre-experimental vs. post-experimental] × group [G1 vs. G2 vs. CG]) were used to compare the differences between pre- and post-test situations and the differences among groups. The results from the within-group (pre vs. post) comparisons demonstrated significant increases (p < 0.05) in the range of motion of 3.93 and 5.96% for G1 and G2 training groups, respectively, in all joints. No significant changes (p > 0.05) were observed for the CG. The results from the between-group comparisons demonstrated no significant differences (p > 0.05) in the range of motion between G1post vs. G2post (1.15%). Although both exercise orders (from upper to lower limbs and from lower to upper limbs) increased flexibility, no significant variations were observed between the different exercise orders. Nevertheless, these findings demonstrate that flexibility gains could be obtained with a resistance training program, and thus, more time can be devoted to sports-specific judo training.
