Background: There are various field tests to predict VO2max. The Rockport one-mile walk test and McArdle step test are among them, which are easy to administer and give good result. The purpose of this study was to see the differences in the result of VO2max predicted by Rockport one-mile walk test and McArdle step test in the adult North Indian population. Methodology: A total of sixty college/university students from North India, between the age group of 18 and 25 years, were divided into two equal groups of thirty each. Group A performed Rockport one-mile walk test and Group B performed McArdle step test. Results and Analysis: The mean age (years), height (cm), weight (kg), and VO2max (ml/kg/min) of Group A were 19.73 (±1.34), 172.37 (±8.52), 63.23 (±11.01), and 55.47 (±3.73), respectively, whereas the mean age (years), height (cm), weight (kg), and VO2max (ml/kg/min) of Group B were 19.30 (±1.02), 174.17 (±7.56), 70.03 (±7.11), and 53.12 (±9.37), respectively. T-test applied between both groups, and there is no statistically significant difference found in age (0.164), height (0.392), weight (0.006), and VO2max (0.206) between both groups. Conclusion: This study has concluded that there is no difference between the Rockport one-mile walk test and McArdle step test for the prediction of VO2max. Hence, we can use any of the tests, either Rockport one-mile walk or McArdle step test, for calculating VO2max in any individuals.

Context: Low back pain (LBP) is one of the commonly prevailing disorders, and the leading source of causing disability globally. Spinal mobilization is commonly used in the clinical practice. According to some studies, it is evident that mobilization to the spine can be helpful in lessening pain. Aims: The purpose of the current study was to check the comparative effectiveness of Maitland Grade 1 and 2 mobilizations with mulligan snags mobilization in the treatment of nonspecific LBP. Subjects and Methods: A sample of 40 patients (mean age 35.25 years) who met with the inclusion conditions were recruited in the current study. Twenty patients each were divided into both treatment groups. Written informed consent took from each individual participating and divided randomly into two groups. In “Group A” Maitland technique, Grade 1 and Grade 2 were applied, whereas in “Group B” mulligan snags mobilization technique was applied along with infrared therapy as baseline treatment for 2 weeks. Oswestry disability questionnaire and the Numeric Pain Rating Scale (NPRS) were used for assessment pre- and post-treatment. Statistical Analysis: SPSS version 21 was used. The Independent t-test was used between-group comparison and paired sample t-test was used for within-group comparison. Results: Mean difference between pre- and post-treatment values for NPRS and Oswestry Disability Index in Group A was 4.40 ± 1.31 and 24.95 ± 7.702, respectively, whereas in Group B was 3.20 ± 1.105 and 22.60 ± 9.202, respectively, with significant value of P= 0.003. Conclusions: It was concluded that mulligan mobilization is more effective than Maitland mobilization for LBP treatment. Mulligan mobilization not only decreased pain but also improved the functioning of the spine.

Soccer being a high contact sport demands physical ability from athletes to show better performance in training sessions and competition. Every sport requires specific training, likewise soccer training needs to be well designed according to demands required for the sport. The training needs to be organized through a season to help an athlete reach his optimal performance. Many variables should consider in the training program to enhance the performance, such as strength training, endurance training, aerobic and anaerobic training, flexibility training, and fitness training. However, this literature review aimed to discuss and highlight different aspects related to skills which are required for strikers in soccer during the preseason period. Literature suggests that “depending on player position during game, soccer team could cover various distances on field.” Fitness is equally important for all players like midfield player, defender, and striker. A study has shown that the central midfield player covered a high average of around 12 km while the defender covered the smallest distance with 10.6 km and the striker is in between the two players' averages, with 11.25 km. However, the striker is involved in different activities on field such as sprinting, jogging, running, walking, dribbling with the ball, changing direction, shooting the ball, kicking, hitting the ball, passing the ball, tackling, and being tackled. Therefore, the striker needs to focus on lower limb strengthening along with other trainings to perform these activities. In short, understanding the athlete's physical requirements is very essential to design a specific strengthening preseason program which could help the athlete to perform through 90 min of match or training session.

Many life-threatening medical illnesses are caused by physical inactivity. The rising awareness of this issue has motivated people to incorporate sports into their daily activities. Resistance training (RT) is a popular form of training, and there are an increasing number of people practicing it due to its enormous range of health benefits. The possibility of injuries while practicing RT raises the question of whether RT is safe and worth the health benefits. Most RT injuries are preventable by various corrective actions that can be easily taken. Most RT injuries occur in the shoulder, back, and knee joints. Shoulder injuries can be of the acute or overuse type and are caused by biomechanical and physiological factors that can be addressed and corrected. Back injuries occur mainly in the lumbar area. Injuries vary from traumatic to overuse injuries. Lumbar kinematics and physiological components are the main factors that contribute to injuries, which can be prevented by adjusting the method of training, using proper machines, and using protective equipment. Knee injuries are the least common injuries. They are caused by the biomechanical and physiological changes caused by repeated flexion and extension while bearing weight during RT. Furthermore, anatomical knee joint abnormalities expose the knee injuries. Early detection of these abnormalities, proper training, and good coaching could prevent such injuries.

We present the case of a 49-year-old patient brought to the hospital with sudden onset of pain and swelling after falling down on a flexed knee while playing football. In the history review, the patient denied any patellar dislocation, previous injury, and surgical interventions. Examination revealed a grossly swollen knee anteriorly, with tenderness and moderate-to-severe effusion. Magnetic resonance images showed injury to the medial patellofemoral ligament and loose cartilage fragments, which is a rare occurrence without patellar dislocation. Surgery was done 5-day postinjury. To prevent the future complication of the injury, the patient underwent open reduction and internal fixation of the osteochondral fragment with 3.0-mm cannulated screw. After a year, the patient underwent the removal of screw and diagnostic arthroscopy, which portrayed that the patella cartilage had healed. The patient return to playing football 9 months after the surgery.

Background: Phosphorus availability during exercise is believed to positively affect adenosine triphosphate availability, increase glycogen synthesis, and enhance exercise performance. Aim: The aim of the present study was to examine the effect of potassium phosphate intake after exercise on physiological responses during subsequent running at anaerobic threshold and on appetite and food intake postexercise in men. Settings and Design: Nine moderately active young men (age, 22 ± 3 years; body mass index, 22.3 ± 3.0 kg/m2; and peak oxygen uptake (VO2peak) 48.5 ± 6.3 ml/kg/min) underwent two experimental conditions. Each condition consisted of two time-to-exhaustion treadmill running tests (time to exhaustion [TTE]) (bout 1 and 2), separated by 3 h recovery. During the recovery, either 500 mg phosphorus in the form of potassium phosphate or placebo was consumed with a glucose solution (1.2 g glucose/10 ml water × body weight) over 3 h. Methods: Expired gas was collected during the running. Appetite using visual analog scale and food intake from access to an ad libitum meal were measured after the second TTE run. Exercise intensity, VO2,and running speed were 67 ± 3% VO2peak, 32.3 ± 4.5 ml/kg/min, and at 10.1 ± 1.1 km/h, respectively. Statistical Analysis Used: Data were checked for normality, and Kolmogorov–Smirnov test was performed. Physiological variables, duration of exercise tests, and postexercise food intake and appetite sensations were analyzed using univariate ANOVA with interaction of exercise order and conditions. Results: There was no group effect in running time of the 2nd TTE although running time was reduced by ~ 5% in the placebo condition and by ~ 37% in the potassium phosphate condition in comparison to running time of the 1st TTE. A group × time interaction was present for the 1st exercise bout (P = 0.03). There were no interactions of condition (placebo and potassium phosphate) and running bouts (1st and 2nd) on respiratory exchange ratio, whole-body fat oxidation, and carbohydrate oxidation, but the interaction effect on VO2trended toward significance (F = 3.97, P = 0.06). There were no differences between conditions for appetite sensations and food intake. Conclusions: An acute dose of potassium phosphate after exercise did not affect subsequent exercise performance, exercise-induced substrate oxidation, and food intake. Potassium phosphate did not seem to affect metabolic responses and appetite in an ecological setting with repeated exercise and access to food during recovery.
