“…Also, there is strong scientific evidence about evolutionary and genetic relations and patterns between the quality of hand grip strength as a suitable phenotype for identifying genetic variants of importance to mid-and late-life physical functioning [7]. Also, handgrip strength is indicative of blood testosterone level and appears to be one of the signals for genetic quality in males [8], and it seems that should predict reproductive success at females [2].…”

The Aim. The aim of this paper is to define the contractile characteristics of maximal isometric handgrip force and to establish possible differences between the students of the Universities of Chelyabinsk and Belgrade. The secondary aim is to create a practically applicable initial model in order to explore the mentioned characteristics in the future. Material and methods. For the purposes of this research, the overall sample of 225 subjects was tested. 91 subjects were from Russia and 134 were from Serbia. The results were gathered using a strain gage and a standardized isometric handgrip test protocol. The contractile properties of HG muscle force were measured in relation to three different contractile dimensions: the maximal muscle force (F max ), the maximal explosive muscle force (RFD max ), the time need for achieving maximal (tF max ) and maximal explosive (tRFD max ) muscle force. Results. This study has shown that there are no generally statistically significant differences for all observed variables of HG contractile characteristics between tested Russian and Serbian students. Based on the results of the present study, six different models of the equation for evaluation of HG contractile characteristics of female and male students, i.e. young adults, were made. All defined models are highly statistically significant, accurate and sensitive in the prediction of the general distributive position of an individual or particular group of subjects in relation to the measured contractile characteristics. Conclusions. The obtained results can generally indicate the stability of potential to exert the given contractile characteristic in relation to the population of similar evolutionary (Slavs) at different geographical background.

“…(Calvo et al 2002;Ortega et al 2008). HGS has thus been shown to be related to reproductive success, dominant behavior, physical performance, and sexual function (Atkinson et al 2012;Gallup et al 2009;Page et al 2005).…”

This study investigated the link between handgrip strength and self-rated physical attractiveness, sexual history, and social characteristics in 145 male university students. Handgrip strength correlated with both height and weight, as well as self-perceived happiness, health, social confidence overall physical attractiveness, and overall number of sexual partners. It also correlated with self-assessed physical fitness levels and there was a predictable link between handgrip strength and age of first sexual intercourse. It is argued that handgrip strength is an indicator of both genetic quality and developmental health. Limitations of the study are acknowledged.

“…In humans, perceived attractiveness and mate quality can be manipulated by artificially lowering the pitch of male voices or artificially increasing it in female voices, commensurate with sex-typical vocal properties (Collins, 2000;Feinberg, Jones, Little, et al, 2005). In fact, there is evidence for increased reproductive success in traditional societies for both low-pitched males (Apicella, Feinberg, & Marlowe, 2007), and high-pitched females (Atkinson et al, 2012).…”

Vocal modulation during courtship increases proceptivity even in naive listeners

Speakers modulate their voice when talking to infants, but we know little about subtle variation in acoustic parameters during speech in adult social interactions. Because tests of perception of such variation are hampered by listeners' understanding of semantic content, studies often confine speech to enunciation of standard sentences, restricting ecological validity. Furthermore, apparent paralinguistic modulation in one language may be underpinned by specific parameters of that language. Here we circumvent these problems by recording speech directed to attractive or unattractive potential partners or competitors, and testing responses to these recordings by naive listeners, across both a Germanic (English) and a Slavic (Czech) language. Analysis of acoustic parameters indicates that men's voices varied F 0 most in speech towards potential attractive versus unattractive mates, while modulation of women's F 0 variability was more sensitive to competitors, with higher variability when those competitors were relatively attractive. There was striking similarity in patterns of social context-dependent F 0 variation across the two model languages, with both men's and women's voices varying most when responding to attractive individuals. Men's minimum pitch was lower when responding to attractive than unattractive women. For vocal modulation to be effective, however, it must be sufficiently detectable to promote proceptivity towards the speaker. We showed that speech directed towards attractive individuals was preferred by naive listeners of either language over speech by the same speaker to unattractive individuals, even when voices were stripped of several acoustic properties by low-pass filtering, which renders speech unintelligible. Our results suggest that modulating F 0 may be a critical parameter in human courtship, independently of semantic content.
