Training

High Intensity Interval Training (HIIT) is a popular form a cardiovascular exercise. Like any number of exercise there are more than a couple of variations you can work into your workouts. A study published in the journal Medicine & Science in Sports & Exercise tested 3 different protocols.
 
All 39 male and female subjects performed 10 sessions of 8 to 10 sets of 60 second all out cycling with 75 seconds of recovery between each bout before being assigned to another 10 sessions of sprint interval training, high volume interval training or periodized interval training.
 
Compared to a control group of adults who didn’t exercise, all subjects experienced significant increases in maximal oxygen consumption, with the greatest improvement seen in high volume interval training. Cardiac output also improved with no changes in maximal heart rate.

It’s easy to see how texting or talking on a cell phone during exercise could reduce the impact of the effort. A study published in the journals Computers in Human Behavior and Performance Enhancement & Health suggests multi-tasking with your phone can also have a negative effect on balance.
 
Researchers had 45 college students text, talk and listen to music on their cell phones while exercising. Texting reduced postural stability by 45%. Talking reduced this measurement of balance by 19%, but just using the phone to listen to music has no impact on balance.

The training practices of any team will have similarities and differences compared to other teams in their league. A study published in the Journal of Strength and Conditioning Research compares the strength and conditioning training of elite rugby teams in the northern versus southern hemisphere.
 
After analyzing responses from 40 international level and professional coaches who completed a questionnaire, it was determined that the main difference amounted to testing methods for determining aerobic capacity and endurance. Coaches in the northern hemisphere tended to place greater emphasis on strength and power development while their counterparts in the southern hemisphere focused more on training integration.
