The Impact

Whole-body electromyostiulation (WB-EMS) has experienced a boom in recent years, even though its effectiveness is controversial. A sedentary lifestyle is deeply rooted in the European population, mainly in the elderly. This experimental study analyzed the impact of WB-EMS on the physical fitness of postmenopausal women. Thirty-four healthy sedentary women between 55 and 69 years followed an experimental design pre–post-test. Both groups conducted a ten-week aerobic and strength training program. The experimental group overlaid the WB-EMS during exercise. At the end of the intervention, both groups improved upper and lower body strength, lower extremity flexibility, agility, and speed levels (pBonferroni < 0.05). Significant interactions were observed at upper and lower body strength, agility, speed, and cardiovascular endurance (p < 0.05). The WB-EMS group scored better agility than the control group at the end of the intervention (pBonferroni < 0.05) and was the only group that improved cardiovascular endurance. WB-EMS shows a favorable isolate effect on the development of dynamic leg strength, agility, and cardiovascular endurance but did not in dynamic arm strength, gait speed, balance, or flexibility of postmenopausal women.

Objective: To evaluate whetherdaily mobile-phone delivered messages with training instructions during three months increase physical activity and overall mobility in patients soon after stroke or transient ischemic attack. Design: Randomised controlled trial with intention-to-treat analyses. Setting: University hospital. Data collection from November 2016 until December2018. Subjects: Seventy-nine patients (mean (SD) age 63.9 (10.4) years, 29 were women) were allocated to either intervention ( n = 40) or control group ( n = 39). Participants had to be independent (modified Ranking Scale ⩽2) and able to perform the six-minute walking test at discharge from the hospital. Interventions: The intervention group received standard care and daily mobile phone instructional text messages to perform regular outdoor walking and functional leg exercises. The control group received standard care; that is, primary care follow-up. Main measures: Walking performance by six-minute walking test (m), lower body strength by five times chair-stand test (s), the short physical performance battery (0–12 points) and 10-metres walk test (m/s) were assessed at baseline and after three months. Results: The estimated median difference in the six-minute walking test was in favour of the intervention group by 30 metres (95% CI, 55 to 1; effect size 0.64; P = 0.037) and in the chair-stand test by 0.88 seconds (95% CI, 0.02 to 1.72; effect size 0.64; P = 0.034). There were no differences between groups on the short physical performance battery or in 10-metres walking time. Conclusions: Three months of daily mobile phone text messages with guided training instructions improved composite mobility measures; that is, walking performanceand lower body strength. Clinical Trial Registry: The study is registered with ClinicalTrials.gov , number NCT02902367.

Strength and conditioning coaches frequently use traditional resistance training (TRT) to build strength. However, in recent years, whole-body electromyostimulation (WB-EMS) was used in elite athletes to increase muscle strength. This study aimed to assess the effect of two different types of training on muscular strength. Sixty female collegiate players (Age = 23.52±1.89 years, Height = 156.20±1.71cm; Mass = 53.21±3.17kg) participated in this study and were randomly assigned to three training groups. All groups trained as usual for eight weeks, except for the first group, which received additional TRT. The second group received additional electrical stimulation training, and the third group did not receive any additional training following the regular softball bat swing training. Muscular strength (upper and lower body) was assessed by a 3RM bench press and a 3RM squat test before and after the eight-week programme. The primary findings indicate that after eight weeks of training, upper body and lower body strength increased significantly in both the TRT and WB-EMS groups (p = 0.000 and p = 0.000, respectively) in comparison to the control group. However, the t value indicated that the TRT group improved both upper body strength (20.18) and lower body strength (29.18) more than the WB-EMS group (upper body = 6.18; lower body = 6.47). The findings demonstrate the efficacy of both training modalities for increasing muscular strength and suggest that TRT be prioritised over whole-body electrical stimulation training for increasing muscular strength in collegiate softball players.

Abstract Background To evaluate the effects of two interactive cognitive-motor programs in processing speed, lower-body strength, and body composition in community dwellings at risk of falling. Methods Forty-eight community dwellings (75.0 ± 5.4 years) completed this randomized controlled trial, were allocated into three groups: 1) experimental group 1 (EG1: psychomotor intervention program); 2) experimental group 2 (EG2: combined program [psychomotor intervention program + whole-body vibration]); and 3) control group (kept their daily life routines). Participants were assessed at baseline, at post-24-week intervention, and after a 12-week no-intervention follow-up. Results Significant improvements were induced by EGs programs in processing speed, lower-body strength, and bone mass (p < 0.05). The treatment effect was similar in both EGs in processing speed and lower-body strength, and higher in bone mineral content and density within EG2. The number of falls decreased by 44.2% in EG1 and 63% in EG2 (p < 0.05). After the follow-up, improvements in processing speed were maintained, particularly in EG2, but were reversed in lower-body strength in both EGs, as were in bone mineral content and density, particularly within EG2 (p < 0.05). Conclusions Both interactive cognitive-motor programs were accepted and well tolerated by the participants, inducing similar improvements in cognitive and physical functions and decreased the fall rate. Additionally, the combined program led to additional benefits in bone mass. This evidenced that both programs were effective for fall and injury prevention.

Purpose: To investigate the potential associations of maternal prepregnancy body mass index (mppBMI) and gestational weight gain (GWG) with physical fitness in children. Methods: A random sample of 5125 children and their mothers was evaluated. The mothers provided data contained in their medical booklets and pregnancy ultrasound records. The data from 5 physical fitness tests (eg, 20-m shuttle run, 30-m sprint, vertical jump, standing long jump, and small ball throw) were used to assess children’s cardiorespiratory fitness, speed, explosive power, and lower and upper body strength, respectively. Results: MppBMI was inversely associated with cardiorespiratory fitness (b = −0.02), lower body strength (b = −1.01), upper body strength (b = −0.07), and speed (b = 0.04). Also, GWG was unfavorably associated with cardiorespiratory fitness (b = −0.02), lower body strength (b = −1.12), upper body strength (b = −0.03), and speed (b = 0.03), after adjusting for sex, birth weight, and children’s BMI (all P values < .05). Children of mothers with an mppBMI ≥ 25 kg/m2 and excess GWG had almost 30% and 20% increased odds for low performances in physical fitness tests than those of mothers with an mppBMI < 25 kg/m2 and adequate GWG, respectively. Conclusions: Antenatal factors such as increased mppBMI and excess GWG could play an unfavorable role in the future health of the offspring.

11507 Background: Cancer-related fatigue (CRF) is a persistent daily lack of energy commonly experienced by breast cancer (BC) patients. Due to CRF, BC patients have difficulties carrying out daily activities, become less active and consequently reduce muscular strength. Exercise can improve muscular strength and increase energy level; therefore it may alleviate CRF. This phase II RCT assessed the effects of exercise on CRF and muscular strength in BC patients. Methods: Ninety BC patients (55.5±9.6 years, 79% white, 48% and 46% under radiation or hormone therapy) were randomized into two arms: a 6-week Exercise for Cancer Patients (EXCAP) program or standard care (Control). EXCAP is a home-based, personalized, progressive exercise program combining aerobic walking and resistance band training. The Brief Fatigue Inventory was used to assess CRF and CRF interference with daily activities and a 7-10 repetition maximum chest press and leg extension strength test was used to assess upper- and lower-body strength at pre- and post-intervention. T-tests and ANCOVA with pre-intervention as the covariate were used to analyze within- and between-group changes, respectively. Results: Participants in the EXCAP group decreased CRF (-0.9±0.3, p = 0.01) and CRF interference with daily activities (-1.1±0.3, p < 0.01) from pre- to post-intervention while participants in the Control group did not. The mean improvement (from pre- to post-intervention) in CRF and CRF interference of daily activities for the EXCAP group were significantly higher than the change in the Control group (both p < 0.01). Participants in the EXCAP group increased upper- (3.9±1.4, p < 0.01) and lower-body strength (6.4±1.3, p < 0.01) from pre- to post-intervention, while participants in the Control group did not. The mean increase (from pre- to post-intervention) in lower-body strength for the EXCAP group was significantly higher than the change in the Control group (p = 0.01). Conclusions: Exercise combining aerobic walking and resistance band training reduces CRF and CRF interference with daily activities and improves muscular strength in BC patients. Results from this study provide further evidence of the benefits of exercise for supportive cancer care. Clinical trial information: NCT00851812.

Lower Body Strength

In athletics, strength plays a special role, given that its development is focused on improving the speed of movement. The main form of expressing strength in athletics is speed-strength (explosive strength, take-off), which is representative for sprinting, jumping and throwing. Specialised studies have revealed that one of the most effective training methods used to develop explosive strength, also called explosive power, is the training based on plyometric exercises, but studies regarding the use of this method for the prepubertal age segment in athletic training are scarce. The purpose of this research is to investigate the degree of improvement in explosive strength in preadolescent athletes with the help of weekly plyometric training as compared to the control group. The research was carried out at the School no. 190 between 20 February and 17 June 2017. In order to conduct the experimental research, 42 athlete subjects of both genders, aged 11 to 13 years, were investigated. The experimental group was made up of 20 athletes, members of the Municipal Sports Club in Bucharest. The control group included 22 athlete subjects of both genders, who were trained by other coaches. Both groups performed four training sessions per week for 17 weeks. Analysing the results of the experiment, we can conclude that plyometric workouts contribute to the development of lower body strength in preadolescent athletes.

Purpose: To assess the effects of periodized versus nonperiodized dry-land strength training (DLST) on indices of swimming performance in well-trained adolescent swimmers. Methods: Sixteen athletes (10 boys and 6 girls; age 14.9 [1.1] y) performed similar endurance training for 16 weeks (29.1 [7.5] km·wk−1). During weeks 1 to 7, all athletes additionally performed 2 or 3 times weekly whole-body DLST (3 × 6–10 repetitions at 75–85% 1-repetition maximum [1RM]). Thereafter, the DLST frequency was maintained, but athletes were stratified into periodized (experimental, n = 9) and nonperiodized (control, n = 7) DLST groups. The experimental group performed maximal (3 × 3–4 repetitions at 85–90% 1RM) and explosive DLST (throws and unloaded jumps), while in the control group, DLST was maintained. Results: Swimming time at 4 mmol·L−1 of blood lactate improved after 7 weeks in both the experimental (+2.6% [1.8%], P = .033) and the control groups (+3.2% [2.4%], P = .081) and plateaued thereafter. Ten-meter start improved in both the experimental (−3.6% [2.5%], P = .039) and the control groups (−5.1% [2.2%], P = .054) throughout the entire intervention. Both groups improved in maximal weight lifted in half-squat (experimental, +19.6% [14.9%], P = .021; control, +25.7% [18.4%], P = .054) and bench press (experimental, +14.1% [4.8%], P = .018; control, +19.3% [11.1%], P = .051). Countermovement-jump height increased only in the experimental group throughout the intervention (+19.4% [7.0%], P = .024). The associations for the pooled changes in half-squat performance and 4 mmol·L−1 of blood lactate were statistically significant (r = .560, P = .024). Conclusions: The findings do not support the superior effects of DLST periodization in adolescent swimmers. However, the association between improvements in lower-body strength and swimming performance still indicates the importance of muscle strength in this age group.

The Impact

(1) Background: Regucalcin or senescence marker protein 30 (SMP30) is a Ca2+ binding protein discovered in 1978 with multiple functions reported in the literature. However, the impact of exercise training on SMP30 in humans has not been analyzed. Aging is associated with many detrimental physiological changes that affect body composition, functional capacity, and balance. The present study aims to investigate the effects of whole body vibration (WBV) in postmenopausal women. (2) Methods: A total of 13 women (aged 54.3 ± 3.4 years) participated in the study. SMP30, body composition (fat mass, lean mass, and bone mass) and physical fitness (balance, time up and go (TUG) and 6-min walk test (6MWT)) were measured before and after the 12 weeks of WBV training. (3) Results: The WBV training program elicited a significant increase in SPM30 measured in plasma (27.7%, p = 0.004) and also in 6MWT (12.5%, p < 0.001). The WBV training also significantly reduced SPM30 measured in platelets (38.7%, p = 0.014), TUG (23.1%, p < 0.001) and total body fat mass (4.4%, p = 0.02). (4) Conclusions: There were no significant differences in balance, lean mass or bone mass. The present study suggests that 12 weeks of WBV has the potential to improve SPM30, fat mass, TUG and 6MWT in postmenopausal women.
