EMG of the Vastus Lateralis (VL), Rectus Femoris (RF), Vastus Medialis (VM) and Biceps Femoris was recorded with pairs of silver chloride circular (recording diameter of 10 mm) surface electrodes (Swaromed, Nessler Medizintechnik, ref 1066, Innsbruck, Austria) with an interelectrode (center-to-center) distance of 20 mm. Recording sites (belly of each muscle, as distal as possible from the hips when the subject was asked to contract his quadriceps at a knee angle of 10 deg) were then carefully adjusted at the beginning of each testing session (electrode placement was drawn on the skin with permanent marker to ensure reproducibility of the recording site). Low resistance between the two electrodes (< 5 kΩ) was obtained by shaving the skin, and dirt was removed from the skin using alcohol swabs. The reference electrode was attached to the patella of the right knee. Myoelectrical signals were amplified with a bandwidth frequency ranging from 10 Hz to 500 Hz (gain: VL = 500; RF and VM = 1000), digitized on-line at a sampling frequency of 2 kHz using a computer, and stored for analysis with commercially available software (Acqknowledge 4.2 for MP Systems, Biopac Systems Inc., Goleta, USA). Due to the pressure of the thigh on the dynamometer chair, the Biceps Femoris EMG signal quality was impaired (e.g. numerous artefacts, problems with electrodes) and therefore not analyzed.

Did you know that there are actually four types of exercise, all of which serve varied purposes? Everyone knows that routine exercise is very important for healthy adults for varied functions, including bone and muscle strength, weight-loss or weight maintenance, heart health and even cognitive health. But there are four different types of exercise: Aerobic (or endurance), strength, flexibility and balance.

Several exercises from Week 1 are carried over to Week 2, but one move is added to each bodypart routine—with the exception of abs—so you can train all muscle groups more completely from multiple angles. Chest, for example, includes two exercises: One is a compound movement (dumbbell bench press) that involves multiple joints (both the shoulder and elbow) to work the largest amount of muscle possible, and the other is an isolation exercise (dumbbell flye) that involves only one joint (shoulder) and targets the pecs to a greater extent. (When doing presses for chest, the deltoids and triceps are involved to a degree, meaning presses don’t isolate the pecs as much as flyes do.)

Workouts are an extremely efficient experience for our clients. You will be in and out in less than 30 minutes. You will come in no more than twice per week. Don't worry, that's all the time we need to target all major muscle groups and the cardiovascular system. Our instructors set up the equipment, keep detailed notes, and guide our clients through every step of the workout.

Exercise tests were performed on a cycle ergometer (Lode Excalibur Sport, Groningen, The Netherlands) or on a treadmill (Ergo ELG 55; Woodway, Weil am Rhein, Germany) depending on the sport. Tests on the cycle ergometer started with an initial workload of 80 W (subjects 6 and 7) or 30 W (subjects 4 and 9), the workload was increased by 40 W every 3 min. Tests on the treadmill started at 5.4 km h−1, the speed was increased with 1.8 km h−1 each 3 min (subjects 1, 2, 3, 8 and 10). One subject performed the treadmill test with an inclination of 1% (subject 5). The duration of each test was recorded in seconds. Subjects wore a heart rate monitor (Polar Accurex Plus, Kempele, Finland) for determination of maximal heart rate (HRmax) throughout the exercise tests. After each exercise test, 20 μl of blood was drawn from the right earlobe to determine maximal blood lactate concentration ([La]max) with enzymatic analysis (EKF; Biosen 5030, Barleben, Germany).
Two moves is better than one, right? You may want to do this move on a mat or a towel for padding. Start in a high plank position with core tight. Lower onto both forearms at the same time, maintaining a tight core and level hips. Now push back up onto hands at the same time to return to starting position. Finish by drawing right knee into chest, then left knee into chest, doing a mountain climber.
Matt Sauerhoff, owner of The LIV Method says one of his favorite, fastest and easiest to do on the go moves is the wall squat. “Start with your back against the wall and your heels about a foot off the wall. Bend your knees and slide down the wall until your legs create a 90-degree angle,” he says. “Make sure your knees are aligned over your toes/laces. Press heels into the floor and focus on contracting your abs, pressing lower back into the wall so it’s flat. Hold for 30 seconds.” Combine it with these 30 Fat-Burning Foods and you’ll be melting the fat in no time!

Pharmacologic beta-adrenergic blockade reduces maximal heart rate (HR) during exercise but variable results have been reported for minute ventilation (VE), CO2 output (VCO2), and O2 uptake (VO2). A total group of 19 subjects with mild asthma was studied. We studied 16 subjects from the group who received placebo or pindolol, a beta-adrenergic antagonist, during 1-min incremental exercise on a ... [Show full abstract]Read more

EMG RMS was measured for the following muscles: Vastus Lateralis (VL), Rectus Femoris (RF), Vastus Medialis (VM) and the overall knee extensors (KE; sum of VL, RF and VM). Data are presented as main effect of time and mean (SE). * significantly different from 10% and $ significantly different from 100%, 1 item for P < 0.05, 2 items for P < 0.01 and 3 items for P < 0.001.

In 1890, English-born American physician Edwin Checkley published ‘A Natural Method of Physical Training’ in which he presented his MMB philosophy. Checkley’s exercise method was non-competitive, did not encourage physical or mental exhaustion, and did not require equipment. The aim was ‘to feel naturally light and strong and to have an effective body.’9 Checkley E. A natural method of physical training. New York (NY): William C. Bryant & Co.; 1890. [Google Scholar] Checkley expressed his dismay toward the vigorous and ‘unnatural’ athletic training methods utilized in the gymnasiums at the time, as well as toward the new mechanized ‘muscle-molding schemes’ he referred to as ‘straining’ more than ‘training.’ He criticized the ethics of aggressive performance-enhancing gymnastic and athletic training techniques claiming they were not natural, therefore harmful for the body and mind. In comparison, Checkley described animals in nature that sustain a lifetime of health, fitness, and beauty by performing seemingly effortless movements on a regular basis.9 Checkley E. A natural method of physical training. New York (NY): William C. Bryant & Co.; 1890. [Google Scholar] Perhaps ironically, Checkley’s philosophy and exercises famously ‘converted’ Alan Calvert, the weightlifting pioneer who founded the Milo Bar-bell Company in 1902 and started Strength Magazine in 1914 (Figures 1, 2).12 Beckwith KA.

Tabata Intervals. The great thing about many of these techinques is the time saving aspect, and Tabata Intervals are definitely time savers. Developed by Dr. Izumi Tabata for Olympic athletes, Tabata Protocol is a form of High Intensity Interval Training (HIIT) where 20 seconds of work is coupled with 10 seconds of rest then repeated for 8 total rounds Metabolic profile of high intensity intermittent exercises. Tabata, I., Irisawa, K., Kouzaki, M., et al. Department of Physiology and Biomechanics, National Institute of Fitness and Sports, Kanoya City, Japan. Medicine & Science in Sports & Exercise 1997 Mar;29(3):390-5.. The 20 seconds work/10 seconds rest pattern has been shown to tax both aerobic and anaerobic pathways more — and in less time — than intense exercise with longer rest periods, meaning improved overall cardiovascular fitness. This protocol can be done with running/rowing/swimming, bodyweight exercises, or weighted movements.

"Consider this: Dr. Kenneth Cooper (author of Aerobics, The New Aerobics, Aerobics for Women), the U.S. Air Force Cardiologist who coined the term 'aerobics" (meaning a form of exercise) and has promoted their use for over 25 years, now admits that he was wrong! According to Dr. Cooper, further research has shown that there is no correlation between aerobic endurance performance and health, longevity, or protection against heart disease. He will admit, however, that such activities do carry with them a great risk of injury. Further, he admits that gross-overuse activities such as running are damaging to the body." – Ken Hutchins, SuperSlow Exercise Guild

The novelty of the present study is that of demonstrating the possibility of applying a specific vigorous physical exercise program [17] on healthy elderly adults over 65 years and evaluating its effects on functional capacity using the classical SFT [3]. To administer the high exercise intensity, we used a HR control under continuous accurate visual monitoring by a sport scientist. As expected, after only 12 weeks of training, we found significant enhancements of almost all skills tested. Our results clearly show that our VE program is relevant and has a positive impact on people over 65 in helping them to maintain a high quality of life. The difference from most of the literature [18–22] regards the exercise protocol intensity, which is usually milder than ours. Also, in the aforementioned studies there was a poor attention about the consequences of the exercise program on general quality of life of subjects. They mainly focused on the attenuated risks of falling. On the contrary, the SFTs applied in our study clearly show that our VE program may ameliorate several motor abilities and in turn the general quality of life in healthy elderly adults over 65 years of age. However, two other studies showed that elderly people need to exercise close to their limit of maximum capacity [23, 24] to improve their physical fitness but, unlike the present research, they were conducted on patients who were in deconditioning status linked to their chronic illnesses.
