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

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.

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.

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.

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.

Falls are a major issue among older adults with cancer and lead to interruptions in cancer treatment. Resistance and balance training can prevent falls in older adults, but minimal evidence is available regarding the older cancer population, who often have unique risk factors. We used a pre–post design to assess the feasibility of a remotely delivered exercise program that progressed in difficulty and its efficacy on lower body strength, balance, and falls in older adults with cancer who had prior in-person exercise experience. Twenty-six older adults with cancer completed the intervention. Attendance rate for the virtual component was 97.6% and for the independent component was 84.7%. Participants perceived the program as rewarding and enjoyable (100%), felt this program prepared them to exercise on their own (92%), were confident to continue exercising on their own (81%), and would recommend the program to other patients (100%). The median balance score at baseline and end-of-study was 4 (IQR = 0). The median chair-stand time decreased from 9.2 s (IQR = 3.13) to 7.7 s (IQR = 4.6). A statistically significant difference in lower body strength (r = 0.68, p = 0.001) was detected post-intervention. The findings from this study can inform the design of a larger randomized trial.

Introduction: Substantial evidences demonstrate impaired physical health and decreased psychosocial well-being among patients with coronary heart disease (CHD). Tai Chi is an effective exercise option in cardiac rehabilitation to manage CHDs. There has been an increasing focus on home-based cardiac rehabilitation to improve participation rate, while none of studies emphasized the effect of home-based Tai Chi program. Hypothesis: A group- plus home-based Tai Chi program improves physical function (aerobic endurance, lower-body strength, lower-body flexibility, and agility and dynamic balance), and psychosocial well-being (perceived stress, social support, exercise self-efficacy) among CHD patients. Methods: In this randomized controlled trial, 98 community-dwelling patients with CHD (mean age: 69.2±4.68 years; 69 women; 29 men) were randomized to Tai Chi (n=49) or control group (n=49). Participants in Tai Chi group first attended 6 weeks supervised group-based Tai Chi classes that were scheduled as follows: 2 times/week for week 1 and 2, 3 times/week for weeks 3 and 4, and then 4 times/week for week 5 and 6, with 60 minutes/class. After that, participants in Tai Chi group practiced home-based Tai Chi 4 times/week, 60 minutes for each time, for another 6 weeks. Outcomes, namely, aerobic endurance, lower-body strength, lower-body flexibility, and agility and dynamic balance were tested by 2-Minute Step Test (steps), Chair Stand Test (times), Chair Sit-and-Reach Test (cm), and 8-Foot Up-and-Go Test (seconds), respectively. Other outcomes included perceived stress, social support, and exercise self-efficacy. Data were collected at baseline, post group-based Tai Chi training at 6-week, post Tai Chi intervention at 12-week, and at 24-week follow-up assessment. Generalized estimating equations models were used to compare changes in outcomes over time between groups. Results: Compared to changes in control group, Tai Chi showed significant improvements in aerobic endurance (+12 steps), lower-body strength (+3 times), agility and dynamic balance (log-transformed score: -0.058s), perceived stress, emotional support, belonging support, tangible support, and exercise self-efficacy at 24-week. Significant improvement in lower-body flexibility (4 cm) was only achieved at 12-week, compared to changes in control group. No significant changes in self-esteem support over time between groups were observed. Intervention adherence: Tai Chi=79.6% (39 of 49) (attending ≥75% of total Tai Chi sessions). Attrition rate: Tai Chi=20.4% (10 of 49), control=24.5% (12 of 49). Conclusions: This Tai Chi program significantly improve physical function and psychosocial well-being among CHD patients, indicating that Tai Chi could be taught in group sessions and then continued independently as a home exercise routine for health promotion in CHD patients.

There is evidence that training for strength and balance prevents decline in physical function in old age when the training is personally instructed. It is an open question whether interventions that deliver training via up-to-date technologies can achieve long-term effects. This study examined the effects of an 8-month fitness training program delivered via information and communication technology (ICT) on lower-body strength and balance in female home care users (n = 72) aged 75 years on average. For statistical analysis, the test group was divided into two subgroups, one who used the program at least 8 times per month (n = 26) and another one who used the program less often (n = 17) compared with a control group that received no exercise program (n = 29). It was found that regular ICT-exercisers exhibited positive effects over time on lower-body strength and balance compared to a decrease in both indicators in irregular exercisers and the control group. The authors see potential in offering exercise programs to people of advanced age via ICT to counteract physical decline in old age.

Abstract Background Muscle weakness is a key risk factor for falls and strength exercises should be included in fall prevention programs. A psychomotor intervention promoting motor stimulation and the whole-body vibration (WBV) providing muscle contractions may reduce the incidence of falls. Our hypothesis relies on the greater benefits of a combined program. This study aimed to evaluate the effectiveness and the feasibility of two 12-week multimodal programs in lower-body strength in community dwellings fallers or with balance impairment. Methods Thirty-seven participants (34 women; mean age 74.3 ± 5.2 years) were allocated into: experimental group 1 [EG1] (psychomotor intervention), or experimental group 2 [EG2] (combined program: psychomotor intervention plus WBV), 3x/week. Maximal strength of knee extensors and flexors was assessed by an isokinetic dynamometer at 60°/s. Wilcoxon and Mann-Whitney tests were performed. Results The overall adherence rate was high (86.3%), with a level intensity in the rating of perceived exertion of 12.1 ± 0.3 points, in EG1, and 12.5 ± 0.4 points, in EG2. Significant changes between the pre-post intervention were observed exclusively in EG2, in the variables ‘Peak torque extension’ (71.7 ± 28.6 Nm vs. 79.2 ± 23.5 Nm, P = 0.042) and ‘Agonist/Antagonist ratio’ (60.2 ± 13.0 vs. 53.5 ± 8.6, P = 0.013). The effect size (r) in both variables was medium. No significant changes between groups were detected. Conclusions This pilot results indicate that both programs were feasible and well-tolerated. The combined program demonstrates larger effectiveness, since the WBV may positively influence the lower-body strength, reducing the risk of falls.

Force Measurement System

This paper presents a force measurement system that can measure a lower-body muscular strength of skaters. The precise measurement and analysis of the left and right lower-body strength of skaters is necessary, because a left/right lower-body strength balance is helpful to improve the athletes' performance and to protect them from injury. The system is constructed with a skate sliding board, a couple of sensor-units with load cell, indicator and control box, guard, force pad, and support bracket. The developed force measurement system is calibrated by the calibration setup, and the uncertainty of the force sensing unit on the left is within 0.087% and the uncertainty of the force sensing unit on the right is within 0.109%. In order to check the feasibility of the developed measurement device, a kinematic analysis is conducted with skater. As a result, the subject shows the deviation of left and right of 12.1 N with respect to average strength and 39.1 N with respect to the maximum strength. This evaluation results are reliable enough to make it possible to measure a lower-body muscular strength of skaters. The use of this measurement system will be expected to correct the posture of skaters and record the sports dynamics data for each athlete. It is believed that through the development of this equipment, skaters in elementary, middle, high schools, colleges, and the professional level have the systematic training to compete with world-class skaters.

Impaired balance and lower body weakness are the main causes of falls, which are considered to be the major cause of fractures and head injuries in the elderly and are recognised as a serious health problem. The aim of this study is to observe the effect of eccentric training, introducing new technologies (gliding discs), on body composition, lower body strength, balance and quality of life. A quasi-experimental study was carried out with 56 healthy participants who were divided into an experimental group (n = 31) who underwent the protocol consisting of 12 training sessions and a control group (n = 25) who did not undergo the training. Before and after the intervention, all participants underwent a measurement of body composition, the SJ jump, balance with accelerometry and quality of life with the Short Form 12 Health Survey. In the experimental group, statistically significant improvements were found in the variables balance and lower body strength. The application of this training protocol improves lower body strength and the ability to control balance in the adult population.
