“…To the author's knowledge, VAS analysis has not been used in the evaluation of play importance in rugby analysis and was adapted from VAS-based research in pain and muscle soreness (11,21,33). In the absence of any normative data for use in this context, analysis ratings were grouped into 4 bands, with ratings of 0-24 mm considered to have no influence, 25-49 mm to have a small influence, 50-74 mm a moderate influence, and 75-100 mm a strong influence.…”

Misseldine, ND, Blagrove, RC, and Goodwin, JE. Speed demands of women's rugby sevens match play. J Strength Cond Res XX(X): 000-000, 2018-The purpose of this study was to quantify the running speed demands of elite female rugby sevens match play, both absolute and relative to maximal ability, and determine the importance of maximal velocity running to performance. Individual maximal running velocity (Vmax) was established for 12 professional female rugby sevens athletes before the collection of global positioning system data during all 6 games of an international tournament. The subjective importance of each maximal velocity running effort was established using visual analogue scale ratings of video clips by coaches. Differences in velocity demands between backs and forwards were analyzed using a one-way multivariate analysis of variance, and differences in "sprint" distance using the typical-standard and female-adjusted sprint thresholds were compared using a paired-samples t-test. The mean peak velocity reached per game by all players was 90.6 6 7.9% Vmax. Players covered 1,556 6 233 m per game, with "sprinting" representing 6 6 4% of this total distance using the typicalstandard "sprint" threshold (5.6 m$s 21), but a significantly (p , 0.001) greater 12 6 4% using the female-adjusted threshold (4.7 m$s 21). Despite similar total distances, backs reached significantly (p , 0.05) greater peak running velocity and covered more distance at sprint, .75% Vmax and .90% Vmax speeds when compared to forwards. More than half of the running efforts peaking at $90% Vmax were considered very influential to game outcomes. These findings suggest that maximal velocity running is important to female rugby sevens performance, and that highspeed demands are different for backs and forwards. Furthermore, the typical-standard sprint thresholds significantly underestimate the true running demands of female rugby sevens.

The work presented in this manuscript has the purpose to assess the relationship between human factors and physiological indices. We discuss the relationship between stress as human factor and cerebral and muscular signals as features. Ten male paraplegic, right-handed subjects were volunteers for the experiment (mean age 34 ±6). They drove a virtual wheelchair in an indoor environment. They filled five missions where, in each one, an environmental parameter was changed. Meanwhile, they were equipped with Electromyography (EMG) sensors and Electroencephalography (EEG). Frequency and temporal features were filtered and extracted. Principal component analysis (PCA), Fisher’s tests, repeated measure Anova and post hoc Tukey test (α = 0.05) were implemented for statistics. Environmental modifications are subject to induce stress, which impacts muscular and cerebral activities. While the time pressure parameter was the most influent, the transition from static to moving obstacles (avatars), tends to have a significant impact on stress levels. However, adding more moving obstacles did not show any impact. A synchronization factor was noticed between cerebral and muscular features in higher stress levels. Further examination is needed to assess EEG reliability in these situations.

“…prolonged reduction in voluntary force and delayed muscle soreness) is induced (Cheung, Hume, & Maxwell, 2003;Thiebaud, 2012). Previous research into muscle damage has usually been based on eccentric exercise (Nosaka, Newton, & Sacco, 2002;Takizawa, Soma, Nosaka, Ishikawa, & Ishii, 2012). These studies reported that Maximum Voluntary Contraction (MVC) did not recover to the level before the exercise by four or five days after exercise Takizawa et al, 2012).…”

<p>There are many studies about muscle strength after eccentric exercise. However, muscle strength after weight resistance exercise including the concentric and eccentric phases, which are usually performed in resistance training, has not been fully investigated. The purpose of the present study was to compare the effects of mid- and high-volume weight resistance exercise on muscle strength. Sixteen subjects were divided into a high-volume group who performed 12 sets (12SET, n=8) and a mid-volume group who performed 6 sets (6SET, n=8). They performed leg extension on the first day. The exercise load was 4~6 RM. The rest between sets was 3 minutes. Maximal voluntary contraction (MVC), isokinetic strength (30°/ sec.: ISOK30, 60°/ sec.: ISOK60, 150°/ sec.: ISOK150, 240°/ sec.: ISOK240), muscle soreness, and thigh circumference were measured before (PRE), after (POST), and 1 day, 2 day, 3 day, 5 day, and 7 day after exercise. The only significant effect was time in all measurements. Although MVC decreased at POST, it recovered to the level of PRE by1 day after exercise. ISOK150 and ISOK240 showed similar results to MVC. ISOK30 showed a lower value at 1 day after exercise. ISOK60 did not change throughout the experiment. Muscle soreness was higher at POST, 1 day and 2 days after exercise. Peak muscle soreness was higher for 12SET than for 6SET. Thigh circumference was higher at POST and 1 day after exercise. These results indicated that muscle damage was lower than previously reported after eccentric exercise. In addition, there was no difference between 12 sets and 6 sets of weight resistance exercise except for peak muscle soreness. Our results suggest that muscle strength after leg extension recovers by two days irrespective of whether 12 sets or 6 sets of high load leg extension are performed.</p>
