Objective Exercise induced muscle damage (EIMD) is one common physiological phenomenon in competitive sports and mass sports. Water immersion recovery and whole body cryotherapy (cryostimulation) (WBC) has become one of the fast recovery methods adopted by high level athletes in the world. The aim of this study was to compare the water immersion recovery and WBC from timing sequential recovery on EIMD, subjective scales, biochemical indicators, exercise performance indicators. Methods Twelve middle and long distance runners from Beijing Sport University were recruited in this study (exercise performance is secondary level in China). All participants performed four models in four weeks which included rest control (CON), cold water immersion(CWI), contrast water therapy (CWT) and whole body cryotherapy (cryostimulation) (WBC) separated by one week. The subjects needed to complete the EIMD exercise program, includes two parts: the treadmill running and the jump step. The individual speed of treadmill running was based on the individual VO2max. running including 5 sets and total time is about 90 min. Every set consist of 6 min flat running, 6 min uphill running and 6 min downhill running. The speed of the treadmill was stable in different stages. The slope of the uphill running is（＋6,＋5,＋4,＋3,＋2）, and the slope of downhill running is (-8, -7, -6, -5, -4). The jump was performed 20 times separated by 30 s via special step ( height is 40 cm) . After the EIMD exercise program, the subjects were treated with different recovery methods immediately after exercise, 24 h, 48 h, 72 h after exercise, while CON group received no intervention. The CWI group was immerged in 15 °C cold water for 12min, and the CWT groups was immerged in 15°C cold water for 1min and 38°C hot water for 1min with 6 cycles. The whole body cryotherapy (cryostimulation) group was immerged in special chamber (-110—-140℃）for 3 min. The three interventions were immerged body to the position of shoulders. The indexes including subjective scales (VAS scale, RPE scale, Borg scale, WHO deep sleep scale, PQSI scale), biochemical indicators (creatine kinase, lactate dehydrogenase, myoglobin, interleukin-6, C reactive protein, SICAM-1), exercise performance indicators ( vertical jump height, grip, running distance). The indexes was collected in different periods (i.e. Before exercise, immediately after exercise,Post1h, Post 24h, Post 48h, Post 72h, Post 96h after exercise etc.). Results  (1) Subjective scales. From results of VAS scale, RPE scale, and Borg scale, the WBC had best recovery effects than the other three interventions (P<0.05).  The recovery effect of the CWI group was similar with the CON group. From results of WHO deep sleep scale and PQSI scale, the WBC group had better recovery effects than CON group (P<0.05). (2) Biochemical indicators. From results of CK, Mb and SICAM-1, the WBC group had better recovery effect than the other three groups (P<0.05). In the LDH, the WBC group had similar effects with the CWT group (P>0.05). From results of CRP and IL-6, the WBC group had better recovery effects than the other three groups (P<0.05).（3）Exercise performance indicators. From results of vertical jump, WBC had lower decrease than the other three groups (P<0.05).  From results of the grip, of the WBC and CWT groups have significant retentive effects than CON group (P<0.05), but there was no significant difference between CON and CWI groups (P>0.05). Conclusions (1)Through combine the treadmill running and the jump step exercise program,Can effectively lead to human body appear the EIMD. (2)WBC has positive effects on the subjective scale, biochemical indicators, exercise performance indicators associated with EIMD.For middle and long distance runners EIMD,compared with CWI CWT,WBC effect is better.(3) CWI and CWT has a positive effect on some subjective scales, biochemical indicators, and exercise performance indicators related to EIMD. However, the positive effect of CWI and CWT is lower than WBC in the extent of action and timing sequence. (4)For the middle and long distance runners EIMD timing sequence recovery effects,WBC have better effects,Followed by CWT , CWI  effect is not significant.

Recovery Methods

Context Among sports-recovery methods, cold-water immersion (CWI), contrast-water therapy (CWT), and whole-body cryotherapy (WBC) have been applied widely to enhance recovery after strenuous exercise. However, the different timing effects in exercise-induced muscle damage (EIMD) after these recovery protocols remain unknown. Objective To compare the effects of CWI, CWT, and WBC on the timing-sequence recovery of EIMD through different indicator responses. Design Crossover study. Setting Laboratory. Patients or Other Participants Twelve male middle- and long-distance runners from the Beijing Sport University (age = 21.00 ± 0.95 years). Intervention(s) Participants were treated with different recovery methods (control [CON], CWI, CWT, WBC) immediately postexercise and at 24, 48, and 72 hours postexercise. Main Outcome Measure(s) We measured perceived sensation using a visual analog scale (VAS), plasma creatine kinase (CK) activity, plasma C-reactive protein (CRP) activity, and vertical-jump height (VJH) pre-exercise, immediately postexercise, and at 1, 24, 48, 72, and 96 hours postexercise. Results For the VAS score and CK activity, WBC exhibited better timing-sequence recovery effects than CON and CWI (P &lt; .05), but the CWT demonstrated better effects than CON (P &lt; .05). The CRP activity was lower after WBC than after the other interventions (P &lt; .05). The VJH was lower after WBC than after CON and CWI (P &lt; .05). Conclusions The WBC positively affected VAS, CK, CRP, and VJH associated with EIMD. The CWT and CWI also showed positive effects. However, for the activity and timing-sequence effect, CWT had weaker effects than WBC.

The Impact

Background: The activity of antioxidant enzymes and sirtuins (Sirt) decreases along with age, which is counteracted by aerobic training. Sirtuins increase antioxidant defence. Whole-body cryotherapy (WBC) increases total antioxidant capacity (TAC) in young men. The aim of our study was to assess the impact of 24 WBC treatments on the blood concentration of selected sirtuins and the level of antioxidant defence as well as oxidative stress index of training and non-training men depending on age. Methods: The study involved 40 males. In each group, there were 10 non-training older and young men (60 NTR and 20 NTR), and 10 older and young long-distance runners (60 TR, 20 TR). During an 8-week period, participants underwent 24 WBC treatments (3 min −130 °C), which were performed three times a week (Monday, Wednesday, Friday). The concentrations of Sirt1, Sirt3, TAC, total oxidative status and the activity of superoxide dismutase (SOD), catalase and glutathione peroxidase (GPx) in the blood were determined before 1 WBC and after 1 WBC, 12 WBC and 24 WBC. Results: After 1 WBC, the activity of GPx and the concentration of Sirt1 and TAC in 60 TR and TAC in 60 NTR increased. After 12 WBC, the level of Sirt1 in 20 NTR and SOD in 20 TR increased. After 24 WBC, the level of Sirt1 increased in 60 TR and in 20 NTR, Sirt3 in 60 TR and SOD in 20 TR. Conclusions: Cryogenic temperatures increase blood levels of Sirt1 and Sirt3 and systemic antioxidant defence in men, but the effect is dependent on age, level of performed physical activity and the number of applied treatments.

For many amateur long-distance runners the marathon is not merely an event – it is a demanding activity, both physically and mentally. While being immersed in this activity they enter the running social world and undergo a process of identity transformation. This process encompasses immersion into a ‘zone’ that is often outside the partnership of marriage and includes absorption into social networks that are unlimited in time and place. In this study, an ethnographic research design was utilized, employing a combination of participant observation, interviews, and website analysis. Key findings illustrate both the complexity and the fragility regarding the encouragement of the non-running partner. It is suggested that, even if the non-running partner is supportive, embracing a serious marathon identity by the running partner can jeopardize the marriage. In other words, the partnership may crumble due to the identity transformation of one of the partners when the other doesn’t play an active part in the new social world.

Purpose:To compare the effects of cold-water immersion (CWI) and whole-body cryotherapy (WBC) on recovery kinetics after exercise-induced muscle damage.Methods:Ten physically active men performed single-leg hamstring eccentric exercise comprising 5 sets of 15 repetitions. Immediately postexercise, subjects were exposed in a randomized crossover design to CWI (10 min at 10°C) or WBC (3 min at –110°C) recovery. Creatine kinase concentrations, knee-flexor eccentric (60°/s) and posterior lower-limb isometric (60°) strength, single-leg and 2-leg countermovement jumps, muscle soreness, and perception of recovery were measured. The tests were performed before and immediately, 24, 48, and 72 h after exercise.Results:Results showed a very likely moderate effect in favor of CWI for single-leg (effect size [ES] = 0.63; 90% confidence interval [CI] = –0.13 to 1.38) and 2-leg countermovement jump (ES = 0.68; 90% CI = –0.08 to 1.43) 72 h after exercise. Soreness was moderately lower 48 h after exercise after CWI (ES = –0.68; 90% CI = –1.44 to 0.07). Perception of recovery was moderately enhanced 24 h after exercise for CWI (ES = –0.62; 90% CI = –1.38 to 0.13). Trivial and small effects of condition were found for the other outcomes.Conclusions:CWI was more effective than WBC in accelerating recovery kinetics for countermovement-jump performance at 72 h postexercise. CWI also demonstrated lower soreness and higher perceived recovery levels across 24–48 h postexercise.

Bifidobacterium longum subsp. longum Olympic No. 1 (OLP-01) has been shown in previous animal experiments to improve exercise endurance performance, but this effect has not been confirmed in humans, or more particularly, in athletes. Toward this end, the current study combined OLP-01 supplementation with regular exercise training in well-trained middle- and long-distance runners at the National Taiwan Sport University. The study was designed as a double-blind placebo-controlled experiment. Twenty-one subjects (14 males and seven females aged 20–30 years) were evenly distributed according to total distance (meters) traveled in 12 min to one of the following two groups: a placebo group (seven males and three females) and an OLP-01 (1.5 × 1010 colony forming units (CFU)/day) group (seven males and four females). All the participants received placebo or OLP-01 supplements for five consecutive weeks consisting of three weeks of regular training and two weeks of de-training. Before and after the experiment, the participants were tested for 12-min running/walking distance, and body composition, blood/serum, and fecal samples were analyzed. The results showed that OLP-01 significantly increased the change in the 12-min Cooper’s test running distance and the abundance of gut microbiota. Although no significant change in body composition was found, OLP-01 caused no adverse reactions or harm to the participants’ bodies. In summary, OLP-01 can be used as a sports nutrition supplement, especially for athletes, to improve exercise performance.

Existing video communication systems, used in private business or video teleconference, show a part of the body of users on display only. This situation does not have realistic sensation because of showing a part of body on display and showing other users by 2D. This makes users feel communicating with the other users at a long distance without realistic sensation. Furthermore, although these existing communication systems have file transfer function such as sending and receiving file data, it does not use intuitive manipulation. It uses mouse or touching display only. In order to solve these problems, we propose 3D communication system supported by Kinect and head mounted display (HMD) to provide users communications with realistic sensation and intuitive manipulation. This system is able to show whole body of users on HMD as if they were in the same room by 3D reconstruction. It also enables users to transfer and share information by intuitive manipulation to augmented reality (AR) objects toward the other users in the future. The result of this paper is a system that extracts human body by using Kinect, reconstructs extracted human body on HMD, and also recognizes users' hands to be able to manipulate AR objects by a hand.
