Background: At present, it is unclear whether older, obese persons with or without sarcopenia respond differently to training. Furthermore, there are no differentiated recommendations for resistance training for this special target group. Objectives: The objectives are to investigate the changes in the physical parameters of older, obese men caused by training and to reappraise the modalities of resistance training for older persons. Design: Pre-test-post-test design. Participants: The participants were 33 physically inactive and obese older men (≥ 65 years, BMI ≥ 30 kg/m2), with-out severe diseases. Subjects were divided into two groups: NSAR (no or presarcopenia, n= 15) or SAR (sarcopenia, n= 18). Intervention: The intervention consisted of progressive resistance training, twice a week for 16 weeks with finally 80-85% of maximum strength and three sets with 8-12 repetitions. The training contained six exercises for the major muscle groups. Measurements: Sarcopenia was assessed using the Short Physical Performance Battery (SPPB), hand-grip strength, skeletal muscle mass index (SMI), and gait speed over a 6-meter walkway. Furthermore, the maximum dynamic strength (1 RM) was assessed. Results: At baseline, the NSAR group had significantly better values in SMI, SPPB score, hand-grip strength, and 1 RM. After training, the results in both groups displayed an increase in 1 RM at the lower limbs (NSAR 18%, SAR 38%) and the upper limbs (NSAR 12%, SAR 14%). Also, the SPPB score (NSAR 11%, SAR 15%) and the 6-m-gait speed (NSAR 5%, SAR 10%) increased. The SAR group was able to increase their right hand-grip strength by 12%, whereas the NSAR group maintained their initial high strength values. SMI did not change in both groups. Conclusions: Both groups show improvements after resistance training with slightly more benefits for men with sarcopenia. Results of this study can be used to define specific training regimens for N(SAR) subjects.

Lower Extremity Strength

The optimal management of sarcopenia requires appropriate endpoint measures to determine intervention efficacy. While hand grip strength is a predictor of morbidity and mortality, lower extremity strength may be better associated with functional activities in comparison to hand grip strength. The purpose of our study was to examine the comparative association of upper and lower extremity strength with common measures of physical performance in older adults. Thirty community-dwelling men, aged 62.5 ± 9.2 years, completed body composition analysis, quantitative strength testing, and performance-based tests of functional status. Hand grip force values were not significantly associated with knee extensor or flexor torque values (p > 0.05). Hand grip force was only associated with fast gait speed, while knee extensor torque at 60°/s was the only variable significantly associated across all functional outcome measures: customary gait speed, fast gait speed, sit to stand time, and the Physical Performance Test (p < 0.02). Hand grip strength was not a proxy measure of lower extremity strength as assessed in this study. Overall, lower extremity muscle strength values had the strongest associations with participant functional performance. Lower extremity strength testing may provide additional value as an endpoint measure in the assessment and clinical management of sarcopenia.

IntroductionAge-related loss of muscle mass, muscle strength and muscle function (sarcopenia) leads to a decline in physical performance, loss of independence and reduced quality of life. Nutritional supplements may delay the progression of sarcopenia. The aim of this randomised, double-blinded controlled trial including 100 participants (≥65 years) is to assess the effect of a marine protein hydrolysate (MPH) on sarcopenia-related outcomes like hand grip strength, physical performance or gait speed and to study the associations between physical performance and nutritional intake and status.Method and analysisThe intervention group (n=50) will receive 3 g of MPH per day in 12 months. The control group (n=50) receive placebo. Assessments of Short Physical Performance Battery (SPPB), hand grip strength, anthropometric measurements, nutritional status as measured by the Mini Nutritional Assessment, dietary intake, supplement use, biomarkers of protein nutrition and vitamin D, and health-related quality of life (EQ-5D), will be performed at baseline and after 6 and 12 months of intervention. Linear mixed models will be estimated to assess the effect of MPH on SPPB, hand grip strength and quality of life, as well as associations between physical performance and nutrition.Ethics and disseminationThe study has been approved by the Regional Committee in Ethics in Medical Research in Mid-Norway in September 2016 with the registration ID 2016/1152. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media, broadcast media and print media.Trial registration numberNCT02890290.

Abstract Background Increased oxidative stress has been shown to lead to muscle damage and reduced physical performance. The antioxidant mechanism is most likely to reduce these relationships, but in the context of the action of carotenoids, more research is needed. This cross-sectional study aims to investigate whether carotenoids modify the association between plasma malondialdehyde (MDA) and physical performance in Korean adolescents. Methods The study sample consisted of 381 participants (164 boys, 217 girls) aged 13−18, who participated in the 2018 National Fitness Award Project. We quantified α-carotene, β-carotene, β-cryptoxanthin, lutein, zeaxanthin, lycopene, and MDA levels in plasma using HPLC with photodiode array detection. Physical performance was measured by determining the absolute and relative hand grip strength, 20-m progressive aerobic cardiovascular endurance run, estimated maximal oxygen consumption, curl-up, and sit-and-reach. Results In boys, the multiple linear regression model adjusted for age, BMI, smoking, drinking, and physical activity showed that the MDA level was negatively associated with absolute hand grip strength; this association was observed only in groups with α-carotene, β-cryptoxanthin, zeaxanthin, and total carotenoid values below the median. Conclusion These results suggest that carotenoids may act as an effect modifier of the association between MDA and physical performance in Korean male adolescents.

To determine the acute effect of an energy drink (ED) on physical performance of professional female volleyball players. 19 females (age= 22.3 ± 4.9 yr.; height= 171.8 ± 9.4 cm; weight= 65.2 ± 10.1 kg) participated in a randomized, crossover, double-blind study to measure grip strength, vertical jump and anaerobic power in 3 different sessions (ED, placebo [PL] or no beverage [CTL]). For each session, participants arrived in a fasted state, consumed a standardized breakfast meal, and 1 hr later completed the 3 baseline performance tests without having ingested the beverage. After completing the premeasurements, the athletes drank 6 ml/kg of body weight of the ED or PL and in the CTL condition no beverage was consumed. Posttest measurements were taken 30 min after the ingestion of liquids. A 3 × 2 repeated-measures ANOVA revealed no significant within-session and measurement time interactions for each performance test. Regardless of the measurement time, right hand grip strength was significantly higher in the ED condition (34.6 ± 0.9 kg) compared with PL (33.4 ± 1.1 kg) and CTL (33.6 ± 1.0 kg) (p > 0.05). Regardless of the beverage ingested, averaged right hand grip strength, taking into account all 3 testing conditions, increased from pre to posttesting (Pre = 33.8 ± 0.9 kg vs. Post = 33.9 ± 1.0 kg; p = 0.029), as did the averaged fatigue index, obtained from the anaerobic power test (Pre = 65.9± 2.2% vs. Post = 68.7± 2.0%; p= 0.049). The acute ingestion of an ED did not improve physical performance of professional Costa Rican female volleyball players.

Shape Characteristics

We adopted allometric models to identify the most appropriate body size/shape characteristics associated with physical performance activities of Greek school children. Children underwent assessments for aerobic and anaerobic fitness, flexibility and hand-grip strength. Results suggest that the inverse Ponderal index and not BMI is the most appropriate body-shape indicator associated with running and jumping activities. Height was negatively associated with flexibility, but both height and weight were positively associated with hand-grip strength. In conclusion, allometric models provide a valuable insight into the most appropriate body size and shape characteristics associated with children’s physical performances and at the same time ensure valid inference when investigating group/population differences (e.g., between gender and maturation status).

Body composition can affect a police officer’s physical performance. We analyzed the correlation between body fat percentage (%fat) and physical performance in 326 male Korean police officers (age, 44.2 ± 9.2 years; height, 174.0 ± 4.5 cm; weight, 76.4 ± 8.8 kg) who were classified into two groups according to their %fat: high-fat (HFG, %fat ≥ 25%; n = 135) and low-fat (LFG, %fat < 25%; n = 191). Physical performance tests included a 100-m sprint, push-ups, sit-ups, and a hand-grip strength test. The results showed significant differences in performance between the groups in the 100-m sprint (p = 0.001) and in the sit-up test (p = 0.033), but not for push-ups (p = 0.130) or hand-grip strength (p = 0.255). A significant positive correlation was found between %fat and the 100-m sprint (r = 0.255, p < 0.000), and a negative correlation was found between %fat and push-ups (r = −0.117, p = 0.035) and sit-ups (r = −0.199, p < 0.000). However, there was no significant correlation between %fat and hand-grip strength (r = −0.093, p = 0.095). To improve physical performance, an intervention training program is recommended for reducing %fat, because high levels of %fat in male Korean police officers were associated with low levels of physical performance.

Objectives: To evaluate whether Mediterranean style diet (MedSD) is associated with better physical performance. There is evidence from large epidemiological studies that MedSD associates with lower risk of chronic disease and mortality. Poor functional capacity, partially affected by poor physical performance, also predicts higher morbidity and mortality resulting in higher healthcare costs. Design: One group, longitudinal pilot clinical intervention trial of 24 weeks total; 12 weeks observation followed by 12 weeks intervention in 16 postmenopausal women (age>65 y) evaluating effects on physical performance. Setting: Outpatient clinical research center. Participants: 16 postmenopausal women (age>65 y) selected for typical American diet. Intervention: Women consumed their typical diet for 12 weeks followed by a 12-week MedSD intervention. A registered dietitian counseled the subjects to make 4 dietary changes: 1) incorporate 3 tablespoons Extra Virgin Olive Oil (EVOO) daily; 2) include 3-5 servings/week of high omega-3 fish (salmon or tuna); 3) incorporate 1.5 ounces of walnuts daily; 4) incorporate increased amounts of fruits, vegetables and whole grains. Measurement: Food frequency questionnaire scores, 3-day diet record, serum total fatty acids, anthropometry, physical activity, functional capacity (chair rise time, single leg time, hand grip strength were measured. Pre-post analysis compared the 2 weeks typical diet period with the 2 weeks MedSD intervention period. Correlations were used to relate dietary change to physical performance change. Results: Diet analysis revealed adherence to the MedSD (p = < 0.001). No significant differences were observed in hand grip strength or the Short Physical Performance Battery. Significant correlations were found between change in chair rise time and changes in intake of carbohydrates (r= 0.587) and trans and saturated fat (r= 0.818). Inability to identify other significant correlations in primary outcomes was likely affected by small sample size and physically robust participant group. Conclusions: Alterations in consumption patterns to adhere to a MedSD, including reductions in saturated fat and carbohydrate consumption, correlate with improvement in chair rise time. This study design can be used for future studies with a larger group of frailer, older adults to assess the effect of MedSD on physical performance.

Background: Prevalence of Indonesian elderly has now reached 7%, which is considerably high. Physical performance is an important health status indicator in elderly. Declining of physical performance such as hand grip strength in elderly is related to oxidative stress. Furthermore, oxidative stress plays an important role on the decreasing of skeletal muscle function. Plasma malondialdehyde (MDA) is a lipid peroxidation residue that is often used as an oxidative stress biomarker. Meanwhile, tea is the most widely drunk beverage after water. Green tea contains antioxidants that can reduce the damages caused by oxidative stress. Objective: To assess the effect of green tea extract (GTE) on plasma malondialdehyde level and hand grip strength of elderly.Method: This was a double-blind experimental with pre-post test and control group. Fifty-seven elderly people from Balai Pelayanan Social Tresna Wredha (BPSTW) Abiyoso and Budi Luhur who met inclusion and exclusion criteria were divided into 2 groups. During 30 days, the first group was given 2 capsules of GTE a day (±168 mg catechin and 95 mg Epigallocatechin gallate (EGCG) and the second group was given a placebo. MDA was measured by thiobarbituric acid  (TBA)method and hand grip strength was measured by handgrip hand grip dynamometer. Results: There was a significant decreasing MDA (p<0,05) in the GTE group, but not in the placebo group. There was also increasing handgrip strength in the GTE group but not in the placebo group. Conclusion: Green tea extract can prevent increasing MDA and declining physical handgrip strength in elderly.
