Abstract

Resistance training (RT) offers benefits to both men and women. However, the studies about the differences between men and women in response to an RT program are not conclusive and few data are available about upper body strength response. The aim of this study was to compare elbow flexor strength gains in men and women after 10 weeks of RT. Forty-four college-aged men ( ± 2.34 years) and forty-seven college-aged women ( ± 2.96 years) participated in the study. The RT program was performed two days a week for 10 weeks. Before and after the training period, peak torque (PT) of the elbow flexors was measured with an isokinetic dynamometer. PT values were higher in men in comparison to women in pre- and post-tests (p 0.05). Effect sizes were 0.57 and 0.56 for men and women, respectively. In conclusion, the present study suggests that men and women have a similar upper body strength response to RT.

Introduction

Strength training (RT) has the benefit of advantages to both males and females. In reality, medical great things about RT were but they are not restricted to: reduced intestinal transportation date; smaller danger of cancer of the colon (Koffler ainsi que al., 1992); enhanced sleeping metabolic process (Campbell mais aussi al., 1994; Paoli ainsi que al., 2012); enhanced glucose k-calorie burning (Hurley, 1994); enhanced bloodstream-lipid users (Brick ainsi que al., 1982; Hurley ainsi que al., 1988); less asleep blood pressure level (Harris & Holly, 1987; Colliander & Tesch, 1988); increased bones nutrient thickness (Menkes et al., 1993); discomfort and pain avoidance for those struggling with arthritis (Rall et al., 1996); decreased lower back pain (Deyssig ainsi que al., 1993; Weinsier ainsi que al., 1995); increased freedom (Westcott, 1995); and you will, improved maximum aerobic capability (Steele mais aussi al., 2012). Particularly, improved fuel and you may muscle, the main effects of RT, was indeed confirmed to attenuate the risk of most of the-result in death (Newman mais aussi al., 2006; Ruiz ainsi que al., 2008; Artero mais aussi al., 2011; Srikanthan & Karlamangla, 2014). not, if you can find sex-certain responses to help you RT was at this time unclear. Considering Dreyer mais aussi al., (2010), generally dudes has 10 moments a great deal more distributing testosterone than just female. Chest system could have more androgen receptors than just knee body (Kadi mais aussi al., 2000). Hence, it’s possible this particular hormones variation you are going to allow greater advancement out-of higher limb looks within the dudes compared to feminine with RT.

) investigated human anatomy structure inside 268 men and you may 200 female having fun with magnetic resonance imaging and discovered chest muscle mass ratio was higher within the dudes than just women (42.nine against. 39.7%). Comparable overall performance was in fact found in resistance-instructed sufferers by the Alway et al. (1989), exactly who compared men and women weight lifters. They reported that, even after undertaking a similar training regularity and you can did comparable education applications, the latest strength cross-sectional a portion of the biceps brachii was higher from inside the males than in females. Furthermore, Kvorning mais aussi al. (2006) unearthed that the consequences from testosterone into power growth could well be far more noticable than simply muscle growth. Ergo, it can be hypothesized that sex you will dictate this new stamina response way more than the increase in muscle tissue in reaction so you can RT.

Prior knowledge reported that visitors doing a similar RT regimen failed to differ in the energy gains, both natural and you will relative, into lower limbs (Ivey ainsi que al., 2000; Galvao et al., 2006; Dorgo et al., 2012). Fisher ainsi que al. (2014) have has just reported the new energy increases out-of female and male students regarding a personal RT studio both for upper and lower system exercises. There were comparable pure stamina increases yet ladies got slightly greater relative electricity development and you may energy growth according to system size. Yet not, women in this research got coached for around twice the fresh cycle of males. Most other studies exploring the upper body report conflicting conclusions with some recommending deeper absolute development for the guys (O’Hagan et al., 1995; Abe mais aussi al., 2000) and you may greater cousin growth in women. Others said zero variations (Davies et al., 1988; Abe et al., 2000). Although not, this has been debated by the Abe ainsi que al. (2000) that many of the earlier studies hence conducted sex contrasting getting each other power and you may muscle hypertrophic changes was in fact hampered from the lower analytical electricity because of short try designs (all ?20 professionals).
