Twelve healthy and recreationally active males completed 4 conditions in randomized order: (i) 5 sets of 30 s calf raises on the platform but without vibration; (ii) 5 sets of 30 s calf raises on the vibration platform with 30 s rest intervals between sets; (iii) 5 sets of 6 drop jump with a 30 s rest interval between sets; (iv) 5 sets of 30 s calf raises on the vibration platform followed by 6 drop jumps with a 30 s rest interval between sets. Before, 3-min after, and immediately after a 3 km run each participant performed CMJ. No significant difference between conditions (p = 0.327) for the 3 km time trial was found. Whereas CMJ height and relative peak power were significantly improved in post-3 km run than at baseline (p < 0.001 and p = 0.025) and post-warm-up (p = 0.001 and p = 0.002) in all conditions. The present study indicates that warm-up consisting of either whole-body vibration, drop jumps, or a combination of both failed to acutely improve CMJ and 3 km volitional pace running performance in physically active males. However, the increase in the CMJ performance was noted after the end of the 3 km run, which may indicate that the warm-up protocols used were insufficient to enhance subsequent performance.

However, no study has verified the changes in gait variability over a longitudinal study involving well-experienced runners. Therefore, the aim of this study was to investigate the changes in gait variability in distance runner before and after a 9-week endurance training program. Methods: A male runner (age 23 years; body mass 58 kg; stature 1.70 m, BMI 20 kg center dot m-2) completed two critical speed (CS) test and six trial at different speeds (calculated by CS) with 9-week of training in-between. At the same time heart rate (HR) was continuously recorded and normalized as a percentage of the maximal heart rate (220 - age) %HRmax, serving as a proxy for metabolic expenditure. Additionally, kinematic (contact time (CT), flight time (FT), step length (SL), step rate (SR)) and kinetic measurements (leg (kvert) and vertical (kleg) stiffness), were recorded. While the running gait variability was calculated as phase coordination index (PCI). Results: CS and HR were 16.40/18.00 km center dot h-1 and 93.19 +/- 1.23/93.81 +/- 2.38 %HRmax in baseline and after the training, respectively. The kinematic and kinetic variables studied at different speeds (13.80-14.40-15.00-15.70-16.40-17.10 km center dot h-1) showed a significative training effect vs baseline conditions for CT (P= .010), FT (P= .010), SL (P= .002), SR (P= .002), kvert (P= .003), kleg (P= .0001). At the same way the metabolic demand and PCI changed significantly after the training compared to the baseline condition for average/maximum HR (P= .009 - 0.024, respectively) and PCI (P= .009). Conclusions: These results suggest that gait variability is one mechanical determinant that demonstrates the adaptation of training load when neuromuscular output related to physiological efforts is under stress conditions, such as running training. Therefore, PCI could be a useful tool for monitoring the impact of running training load on bilateral running coordination.

Two-hundred and forty CNLBP patients (40-70 years; 62% female) were randomly assigned to three intervention arms (WB-EMS: n = 80 vs. WBV: n = 80 vs. CT: n = 80). All training intervention programs were performed for 12 weeks in their usual commercial training setting. Before and during the last 4 weeks of the intervention, MPI was recorded using a 4-week pain diary. Additionally, maximal isometric trunk extension and -flexion strength was assessed on the BackCheck (R) machine. A moderate but significant decrease of MPI was observed in all groups (WB-EMS: 29.7 +/- 39.1% (SMD 0.50) vs. WBV: 30.3 +/- 39.3% (SMD 0.57) vs. CT: 30.5 +/- 39.6% (SMD 0.59); p < 0.001). Similar findings were observed for maximal isometric strength parameters with a significant increase in all groups (extension: WB-EMS: 17.1 +/- 25.5% vs. WBV: 16.2 +/- 23.6% vs. CT: 21.6 +/- 27.5%; p < 0.001; flexion: WB-EMS: 13.3 +/- 25.6% vs. WBV: 13.9 +/- 24.0% vs. CT: 13.9 +/- 25.4%; p < 0.001). No significant interaction effects for MPI (p = 0.920) and strength parameters (extension: p = 0.436; flexion: p = 0.937) were observed. WB-EMS, WBV, and CT are comparably effective in improving MPI and trunk strength. However, training volume of WB-EMS was 43 or 62% lower, compared with CT and WBV.

Acute effects of whole-body vibration warm-up on leg and vertical stiffness during running. J Strength Cond Res 35(9): 2433-2438, 2021-Although whole-body vibration (WBV) has been suggested as a suitable and efficient alternative to the classic warm-up routines, it is still unknown how this may impact running mechanics. Therefore, the aim of this study was to investigate the effect of a WBV warm-up procedure on lower-limb stiffness and other spatiotemporal variables during running at submaximal speed. Twenty-two males performed 30-second running bouts at 4.44 m center dot s(-1) on a treadmill before and after a WBV and control warm-up protocols. The WBV protocol (vibration frequency: 50 Hz, peak-to-peak displacement: 4 mm) consisted of 10 sets of 30-second dynamic squatting exercises with 30-second rest periods within sets. Leg and vertical stiffness values were calculated using the spring mass model. The results indicated significant increases only after the WBV protocol for leg stiffness (3.4%), maximal ground reaction force (1.9%), and flight time (4.7%). Consequently, the WBV warm-up protocol produced a change in running mechanics, suggesting a shift toward a more aerial pattern. The functional significance of such WBV-induced changes needs further investigation to clearly determine whether it may influence running economy and peak velocity.

Methods Triaxial accelerometers were used to quantify the input (heel cup of the shoe) and soft-tissue vibrations of the gastrocnemius medialis and vastus lateralis muscles during seven sport-specific tasks performed by 10 healthy volunteers. A wavelet analysis was used to analyze the acceleration signals in the time-frequency domain. The energy and frequency of the input and soft-tissue vibrations, as well as the transmission of energy from the input to the muscles and the damping properties of soft tissues, were computed. Results Different inputs, energy transmissions, and damping properties were found between the various movements. Landings and side cuts induced the greatest input frequency and energy, as well as the greatest soft-tissue vibration energy. These tasks produced up to three times greater energy than in-line running. Positive energy transmission was found for frequencies under 50 Hz and for frequencies up to 90 Hz for some movements, indicating a possible change in the natural frequency of vibration within muscle. Only small differences in damping properties were found, which may indicate that the attenuation of the vibration was not the priority during these tasks. Conclusions Athletes are subject to greater energy impacts and vibrations during some sport-specific tasks compared with running. It may be useful to decrease such input/vibration energy via the usage of footwear or compression tools to limit their potential deleterious effects on the musculoskeletal system. It is, therefore, recommended to quantify and control the number of impacts induced by the different sport-specific tasks.

The aim of this study was: (1) to determine the surface-electromyography-root-mean-square (sEMGRMS)-acceleration load relationship in the vastus lateralis (VL), vastus medialis (VM), rectus femoris (RF), lateral gastrocnemius (LG) muscles during synchronous WBV, and (2) to assess the reliability of the acceleration corresponding to the maximal sEMGRMS. Methods: Twenty-five sportsman voluntarily took part in this study with a single-group, repeated-measures design. All subjects postured themselves in an isometric half-squat during nine trials in the following conditions: no vibrations and random vibrations of different acceleration loads (from 0.12 to 5.72g). Results: The sEMGRMS were dependent on the acceleration loads in the VL (p=0.0001), LG (p=0.0001) and VM (p=0.011) muscles; while RF was not affected by the acceleration loads (p=0.508). The comparisons among the sEMGRMS-accelerations relationships revealed a significant difference between the LG and the others muscles (p=0.001). No significant difference was found between the different thigh muscles (p>0.05). The intra-class correlation coefficient ranged from 0.87 to 0.99 for the measurements performed on the LG, VL and VM. Conclusions: The sEMGRMS-acceleration relationship in the VL, VM and LG is a reliable test to individualize the WBV intervention. © 2015 Elsevier Ltd.
