Android 4.2 Update JOP40C for GSM Galaxy Nexus Pushing , Google will start selling the Android 4.2 OS powered Nexus 4 handset and Nexus 10 tablet today on Google Play Store and it looks like Google wasted no time and has officially flipped the switch on the release of Android 4.2 Jelly Bean update for the Samsung Galaxy Nexus smartphones. According to the users reports on Twitter and Google+, the new Android 4.2 software update has hit Apple’s servers and is propagating now to the GSM Galaxy Nexuses only. Sorry, no luck for Sprint and Verizon connected CDMA GNexus phones yet. The new firmware bumps the build number up to JOP40C.

Android 4.2 build will carry Photosphere support with 360 degree panorams, improved Google now, Gesture Typing (which is similar to the popular Swype keyboard app), new Clock app, a new screensaver called Daydream, and various other improvements and you can use two fingers or the button at top right of the notification area to access quick settings. Users won’t be able to initially benefit from the much talked about multi user support, which won’t be the part of this Android 4.2 build. And there’s a Triple-tap support magnification which “works everywhere except the keyboard and navigation bar.”

If your rocking a GSM capable Galaxy nexus, and want to check to see if the update has already begun rolling out, you can do so by heading into Menu > Settings > About phone > System updates. Don’t forget to tell us how the update is working for you.

As Meaghan E. Maddigan, Duane C. Button and David G. Behm from the Memorial University of Newfoundland rightly point out, "the back squat is a traditional resistance training exercise." (Maddigan. 2014).

The use of resisted sled exercises, on the other hand, is a relatively new phenomenon of which we dont even know yet how it compares to the classics.

Accordingly, Maddigan et al. set out to compare the muscle activation between squatting and sled pushing on the activity of leg and trunk muscles in ten healthy resistance-trained men in the context of a randomized crossover design study.
The study consisted of 2 preparation sessions and 2 testing sessions. Electromyographic (EMG) activity of the rectus femoris, biceps femoris, gastrocnemius, lower erector spinae, and the transversus abdominis/ internal obliques (TrA/IO) were monitored during a 20-step maximum push with the weighted sled apparatus and a 10 repetition maximum with a bilateral back squat.

All ten subjects were healthy resistance-trained men (age 24.6 years, mass 84.5 kg, height 178.3cm) who had at least 2 years of resistance training and squat experience and were also familiar with performing the sled exercises (however, the volume of squat experiences exceeded sled training volumes or training durations).

Figure 1: Average root mean square (RMS) EMG recorded in exercise phase 1, 2, and 3 (EMG signal was calculated over a 1-second segment of the concentric contraction phase of each step or repetition) from (A) rectus femoris, (B) biceps Femoris, (C) gastrocnemius, and (D) erector spinae during the concentric portion of the sled and squat exercises. Open circles represent the sled condition, whereas the filled squares represent the squat condition (Maddigan. 2014).

As you can see in Figure 1 there were nonsignificant trends for the rectus femoris ( p = 0.092: 8.6– 16.7%) and biceps femoris ( p = 0.09: 10.5–32.8%) to demonstrate higher activity with the sled and squat exercises, respectively. A result based on which you could conclude that

• squatting is better for the quads, while
• sled pushing is th better hamstring exercise

Maddigan et al. also observed main effects for condition with 61.2% greater gastrocnemius EMG with the sled exercise ( p = 0.01) and 74.5% greater erector spinae EMG activity with the squat (p = 0.002). For the transversus abdominis/ internal obliques, however, there were no significant differences between the exercises for the.
