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 worldbrides.org buraya bakin 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
Weight training (RT) has the benefit of positive points to both males and females. In fact, the health benefits of RT is but they are not restricted to: diminished intestinal transportation date; quicker chance of a cancerous colon (Koffler et al., 1992); enhanced sleep kcalorie burning (Campbell et al., 1994; Paoli ainsi que al., 2012); improved glucose metabolism (Hurley, 1994); increased bloodstream-lipid profiles (Stone mais aussi al., 1982; Hurley mais aussi al., 1988); faster resting blood pressure (Harris & Holly, 1987; Colliander & Tesch, 1988); improved bones mineral thickness (Menkes ainsi que al., 1993); pain and discomfort protection for these struggling with joint disease (Rall et al., 1996); reduced lower back pain (Deyssig et al., 1993; Weinsier et al., 1995); improved liberty (Westcott, 1995); and you may, enhanced maximum cardio capability (Steele et al., 2012). Particularly, enhanced strength and you can muscle tissue, the key results of RT, was evidenced to reduce the risk of the-end in death (Newman mais aussi al., 2006; Ruiz et al., 2008; Artero et al., 2011; Srikanthan & Karlamangla, 2014). Although not, whether or not you will find sex-certain responses to help you RT are at this time not sure. Centered on Dreyer et al., (2010), overall guys has actually 10 minutes a whole lot more circulating testosterone than simply female. Chest system might have much more androgen receptors than leg human anatomy (Kadi ainsi que al., 2000). For this reason, you’ll be able this hormone differences you are going to allow greater creativity of upper limb human body when you look at the guys compared to the female which have RT.
) examined body structure inside 268 men and two hundred female using magnetic resonance imaging and found chest area muscle mass proportion is actually better into the guys than female (42.nine compared to. 39.7%). Similar efficiency was basically used in opposition-trained subjects because of the Alway ainsi que al. (1989), which opposed female and male bodybuilders. It reported that, despite doing an identical education volume and you will performed similar education programs, this new muscles mix-sectional the main biceps brachii was highest from inside the males than just in females. Also, Kvorning ainsi que al. (2006) discovered that the consequences regarding testosterone for the stamina growth was alot more obvious than simply muscle development. Hence, it can be hypothesized you to definitely sex you’ll dictate brand new fuel impulse much more compared to escalation in muscles in response so you can RT.
Earlier in the day studies reported that visitors carrying out the same RT regimen don’t differ in electricity increases, both natural and you can cousin, on the hip and legs (Ivey mais aussi al., 2000; Galvao ainsi que al., 2006; Dorgo et al., 2012). Fisher ainsi que al. (2014) have recently said the new strength gains from male and female trainees out of a private RT facility for both top and lower human anatomy practise. There are similar natural electricity gains yet , ladies had somewhat better cousin energy development and you can electricity growth in line with looks size. Although not, ladies contained in this research got educated for about twice new period of men. Almost every other studies exploring the upper body statement conflicting conclusions with many indicating better pure gains within the males (O’Hagan et al., 1995; Abe ainsi que al., 2000) and greater relative gains in women. Others advertised zero variations (Davies mais aussi al., 1988; Abe mais aussi al., 2000). However, it has been argued by Abe mais aussi al. (2000) that many of the sooner degree and that conducted sex comparisons getting each other power and you will muscle hypertrophic change were hampered of the reasonable mathematical stamina resulting from short take to versions (every ?20 players).
