The main strength of this study is the large data material on exercise patterns. Most research on exercise pattern has used a cross-sectional design whereas we followed older adults over a one-year period and collected data from each exercise session they performed. Furthermore, this is the first study to assess differences in exercise patterns between older adults instructed to follow MCT versus HIIT.

In 1988, Richard Simmons released his popular exercise video, Sweatin' to the Oldies, consisting of energy-packed workouts set to music by a live band. In his workouts, Simmons is so lively and enthusiastic that the workout seems less about grueling exercise and more about jovial fun. This is still the case for Simmons—as he said in a 2012 interview with the Chicago Tribune, " I try to be the clown and court jester and make people laugh. At the same time, you have people in the hospital who have had gastric bypass or lap-band surgery and they still have to work out." While Simmons's workouts have been successful, he takes a different approach than that of Fonda by not grouping any given set of his exercises with any one muscle group. You may not know what specific part of your body you're working out, but boy, you still feel it.

Sample characteristics are presented as mean ± standard deviation for continuous variables and proportions for categorical variables. Pearson Chi-square test and independent samples t-test were used to assess potential sex differences. For BMI and weight, a non-parametric test (Mann-Whitney U) was conducted due to the lack of normal distribution. Data from the exercise logs are presented as proportions of the total number of exercise logs. Pearson Chi-square tests were run to assess the associations between frequency, intensity, type, location and social setting of exercise with sex and training group. The results were considered statistically significant if the p-value was less than 0.05. All statistical analyses were performed with SPSS 22 (Statistical Package for Social Science, Chicago, IL, USA).
Start by lying on your back with your feet flat on the floor and your head resting in the palm of one hand and the other hand reaching toward your knees. Press your lower back down. Contract your abdominal muscles (abs) and in one smooth move, raise your head, then your neck, shoulders, and upper back off the floor. Tuck in your chin slightly. Lower back down and repeat.
I’ve recently been using an excellent iPhone app called 7-Minute Workout, which has totally changed my life. Its simple, voice-guided power workouts make it easy to exercise in my bedroom using only my body and some basic props, and the app’s game mechanics help make the experience fun rather than a chore. The best part is that, no matter how busy I am, I always have time for a seven-minute workout. I’m currently rocking a three-month daily workout streak and counting.

The lateral raise (or shoulder fly) is performed while standing or seated, with hands hanging down holding weights, by lifting them out to the sides until just below the level of the shoulders. A slight variation in the lifts can hit the deltoids even harder, while moving upwards, just turn the hands slightly downwards, keeping the last finger higher than the thumb. This is an isolation exercise for the deltoids. Also works the forearms and traps.

This stands for rate of perceived exertion, and refers to intensity. It’s a point of reference that trainers often use to communicate how hard you should be working since what feels easy or challenging is different for everyone. On the RPE scale a 1 pretty much means zero effort while a 10 means you’re working harder than you thought you possibly could.

The thruster is a compound movement, meaning that it is a multi-joint movement that works several muscle groups. HOW TO DO IT: The thruster begins in the front rack position across your chest. Squat down, keeping your chest big and knees out. Drive out of the bottom of the hole, similar to a front squat, while driving your knees out. Then use the force you are creating in the squat to drive the bar overhead. Then lock out your arms overhead. MUSCLES USED: Glutes, quads, hamstrings, calves, core, shoulders, back and triceps.
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.)
This is the first study that has followed older adults instructed to perform MCT or HIIT over a one-year period, collected data from each exercise session they performed and provided descriptive data on their exercise patterns. The main finding is that both groups to a large degree exercised with the prescribed intensity. MCT had a higher proportion of walking sessions than HIIT, while HIIT had a higher proportion of jogging sessions than MCT. In addition, HIIT had a higher proportion of sessions with cycling, combined endurance and resistance training, swimming and dancing. Both groups exercised more frequently outdoors than indoors and performed an equal amount of sessions alone and together with others.
Although there have been hundreds of studies on physical exercise and the immune system, there is little direct evidence on its connection to illness. Epidemiological evidence suggests that moderate exercise has a beneficial effect on the human immune system; an effect which is modeled in a J curve. Moderate exercise has been associated with a 29% decreased incidence of upper respiratory tract infections (URTI), but studies of marathon runners found that their prolonged high-intensity exercise was associated with an increased risk of infection occurrence. However, another study did not find the effect. Immune cell functions are impaired following acute sessions of prolonged, high-intensity exercise, and some studies have found that athletes are at a higher risk for infections. Studies have shown that strenuous stress for long durations, such as training for a marathon, can suppress the immune system by decreasing the concentration of lymphocytes.[26] The immune systems of athletes and nonathletes are generally similar. Athletes may have slightly elevated natural killer cell count and cytolytic action, but these are unlikely to be clinically significant.[27]
The aim of this study was to assess the effects of vigorous exercise on functional abilities by means of a Senior Fitness Test (SFT) in a group of elderly adults. Twenty healthy and inactive people performed vigorous exercise (VE: 12 men and 8 women, aged 69.6 ± 3.9 years). At the beginning of the study (T0) and after 3 months (T1), each subject's functional ability was tested for muscular strength, agility, cardiovascular fitness, flexibility, and balance. The VE was designed with continuous and interval exercise involving large muscle activities. Functional exercises were performed between 60% and 84% of heart rate reserve (HRR) for a duration of 65 minutes. Five out of the 6 SFTs performed were found significantly improved: Chair Stand (T0 12.4 ± 2.4, T1 13.5 ± 2.6, p < 0.01), Arm Curl (T0 14.2 ± 3.6, T1 16.6 ± 3.6, p < 0.01), 2 min step (T0 98.2 ± 15.7, T1 108.9 ± 16.2, p < 0.01), Chair Sit-and-Reach (T0 −9.9 ± 7.7 cm, T1 1.7 ± 6.3 cm, p < 0.01), and Back Scratch (T0 −15.8 ± 10.9 cm, T1 −8.4 ± 13.1 cm, p < 0.01). Our results suggest that a high intensity protocol and functional exercises can improve functional mobility and muscle endurance in those over 65 years of age. SFTs are an effective method for assessing improvements in the functional capacity of elderly adults.
