“…The present study revealed a PhA mean of 5.52° for the total sample, 5.83° for men, and 5.42° for women ( Table 1 ). The observed significant difference between sexes is in line with previous studies in older adults [ 15 , 16 ]. Additionally, this study presented higher values than those reported in other studies performed in older adults with a higher mean age [ 18 , 27 , 45 ].…”

“…In inflammatory processes involving oxidative stress and changes in cell membranes, PhA can be a critical factor in distinguishing the degree of inflammation and cell oxidation within a morphofunctional evaluation protocol [ 11 , 12 ]. Hence, PhA from BIA has been described as a global health marker [ 13 ] and as a muscle index [ 14 ] that can predict several outcomes in older adults, such as physical and muscle function [ [15] , [16] , [17] , [18] ], muscle mass [ 19 ], inflammatory and oxidative stress biomarkers [ 20 , 21 ], total and regional BMD [ 22 ], mortality risk [ 23 , 24 ], upper body strength, agility, and dynamic balance, regardless of the potential confounding effects of sex, age, and skeletal muscle [ 16 ]. In line with the previous statements, it was also possible to verify connections between PhA and the 30-seconds (sec) chair‐stand test, timed up & go (TUG) test, arm curl test and 6-min walking test (6 MWT) in older women [ 25 ].…”

“…This study confirmed the associations between the PhA and the 6 min walk test, 30 s chair stand, 30 s arm curl, timed up and go, gait speed, handgrip strength and physical performance score. These findings support the suggestion that the PhA could be a useful biomarker to estimate physical performance [ 18 , 45 , 46 ]. Besides functional performance, the PhA has been shown to correlate with muscle strength or power [ 47 , 48 ], knee extensor strength [ 49 ] and maximal torque of plantar and dorsal flexion [ 50 ], in middle-aged or older populations [ 51 ].…”

In recent years, the phase angle (PhA) as a raw bioelectrical impedance analysis variable has gained attention to assess cell integrity and its association to physical performance in either sports-related or clinical settings. However, data on healthy older adults are scarce. Therefore, data on body composition, physical performance and macronutrient intake from older adults (n = 326, 59.2% women, 75.2 ± 7.2 years) were retrospectively analyzed. Physical performance was evaluated by the Senior Fitness Test battery, gait speed, timed up and go and handgrip strength. Body composition was determined by the BIA and dual-energy X-ray absorptiometry (from a subgroup of n = 51). The PhA was negatively associated with the timed up and go test and age (r = −0.312 and −0.537, p < 0.001), and positively associated with the 6 min walk test, 30 s chair stand, handgrip strength, gait speed and physical performance score (r = 0.170–0.554, p < 0.05), but not protein intake (r = 0.050, p = 0.386). Hierarchical multiple regression analysis showed that especially age, sex, BMI, but also the PhA predicted the performance test outcomes. In conclusion, the PhA seems to be an interesting contributor to physical performance, but sex- and age-specific norm values still need to be determined.

“…Matias et al [ 17 ] showed a mean value of 5.5° ± 0.7° for the total sample, 5.3 ± 0.5° for women and 5.9 ± 0.7° for men, and revealed significant differences between the sexes. Additionally, Germano et al [ 24 ] showed mean values of 5.9 ± 0.7° for men and 5.4 ± 0.7° for women, and also showed significant differences between the sexes. Another study [ 25 ], where participants had a similar age (80.5 ± 7.0), also showed higher values than our study; 5.2 ± 1.3° for men and 5.7 ± 1.0° for women.…”

The aim of this study was to investigate the relationship between phase angle (PhA) and physical function in institutionalized, independent older adults. Physical function was evaluated using the Senior Fitness Test Battery. PhA was measured by electrical bioimpedance at 50 khz, and body composition parameters were also registered. Results showed that PhA significantly correlated with all physical fitness tests, except for arm curls. Regarding the results of the multivariate analysis, three models were created: Model 1, formed by a dependent variable “PhA” and two predictor variables “8 ft up-and-go” and “6 min walk”; Model 2, formed by a dependent variable “PhA” and three predictor variables “8 ft up-and-go”, “6 min walk” and “30-s chair stand”; and Model 3, formed by a dependent variable “PhA” and four predictor variables “8 ft up-and-go”, “6 min walk”, “30-s chair stand” and “arm curl”. Results showed that predictor variables had a significant influence on the PhA for all three models (Model 1: p = 0.001, 12.5%; Model 2: p = 0.002, 12.9%; and Model 3: p = 0.005, 13.1%). For women, Model 1 showed a significant influence of predictor variables on the PhA (p = 0.030, 9.3%). The results for men in Models 1, 2 and 3 showed significant influences on the PhA (p = 0.002, 31.2%; p = 0.006, 31.6%; and p = 0.016, 31.6%; respectively). This study confirmed previous studies regarding to the relationship between PhA and physical function. It also indicates that PhA could be an excellent predictor of physical function.
