Athletic Pubalgia

PROBLEM

As regards the treatment of a problem of athletic pubalgia, this case was approached through a specific DTS treatment, formed by two main sessions.

TREATMENT

The patient, during the first session, started with a light warm-up in order to activate the dorsal/lumbar area, followed by two balance tests and one isometric test, using Desmotec devices. The result of the tests showed a slight imbalance towards the left side (about 20%). The patient then performed three sets of squats (with variants), using D and two sets of rotation exercises using the V, finishing the first session with three sets of sumo squats on D, equipped with disk type “PRO”. During the second session the patient repeated the same exercises using D and V, obtaining immediate results. The average balance changed from 20% to about 0%, while the pain gradually disappeared.

RESULTS

The Desmotec devices contributed to the identification of the patient’s slight imbalance towards the left side, therefore it was then possible to intervene and solve it along with the problem linked to pubalgia.

Front Squat on D.Sport - Oscar Rivas

ATHLETE

Oscar Rivas is a Colombian professional boxer who fought once for the vacant WBC interim heavyweight title in 2019. He has previously held the IBF International, WBC-NABF and WBO-NABO heavyweight titles. As an amateur he won a silver medal at the 2007 Pan American Games.

EXERCISE

In the video below, he is performing a Front Squat exercise on Desmotec D.Sport. Thanks to this particular workout, he can focus on eccentric training in order to develop and improve reactive power in the lower limbs.

In this case , he is performing 4 shorts movements to create a peak of velocity and then eccentricly absorb it while performing a full squat.  The entire cicle has to be repeated four time.

TRAINING WITH DESMOTEC DEVICES

As the athlete needs to develop peaks of eccentric power and perform this movement for multiple repetitions, Desmotec machines are ideal for this purpose. The eccentric training along with the support provided by the Software D.Soft, allow the user and the trainer to track power peaks in real time, obtaining a complete report about progresses and performances at the end of the exercise. This is a fundamental part in developing a personalized training programme for the athletes in order to gradually improve their performances.

ABSTRACT

Eccentric exercise has often been associated with skeletal muscles structural damage and athletes may experience signs and symptoms such as limited range of motio and muscle soreness of the muscles across the joint. The isoinertial modality provides additional eccentric load. To our knowledge, no previous study has investigated thE effect of isoinertial exercise, which consists of both concentric and eccentric muscular actions, on exercise-induced muscle damage. Aim of the present study is to measure
changes in exercise-induced muscle damage and soreness as result of one isoinertial concentric-eccentric maximal exercise session.

The aim of this study was to evaluate the post-activation potentiation (PAP) effects following eccentric overload (EOL) and traditional weightlifting (TW) exercise on standing long jump (SLJ), countermovement jump (CMJ), and 5 m sprint acceleration performance. DESMOTEC DEVICE D.FULL was used during the research process.

 

Desmotec D.FULL

ABSTRACT

The aim of this study was to evaluate the post-activation potentiation (PAP) effects following eccentric overload (EOL) and traditional weightlifting (TW) exercise on standing long jump (SLJ), countermovement jump (CMJ), and 5 m sprint acceleration performance. Ten male athletes were involved in a randomized, crossover study. The subjects performed 3 sets of 6 repetitions of EOL or TW half squat exercise followed by SLJ, CMJ, and 5 m sprint tests at 1 min, 3 min and 7 min, in separate sessions using a randomized order. Bayes factor (BF10) was reported to show the strength of the evidence. Differences were found using EOL for SLJ distance at 3 min (BF10 = 7.24, +8%), and 7 min (BF10 = 19.5, +7%), for CMJ at 3 min (BF10 = 3.25, +9%), and 7 min (BF10 = 4.12, +10.5%). Differences were found using TW exercise for SLJ at 3 min (BF10 = 3.88, +9%), and 7 min (BF10 = 12.4, +9%), CMJ at 3 min (BF10 = 7.42, +9.5%), and 7 min (BF10 = 12.4, +12%). No meaningful differences were found between EOL and TW exercises for SLJ (BF10 = 0.33), CMJ (BF10 = 0.27), and 5 m sprint (BF10 = 0.22). In conclusion, EOL and TW exercises acutely increase SLJ and CMJ, but not 5 m sprint performance. The PAP time window was found between 3 min and 7 min using both protocols. This study did not find differences between EOL and TW exercises, and so both methodologies can be used to stimulate a PAP response.

ACL Rehabilitation

PROBLEM

In the case of a patient facing an ACL rehabilitation; the whole rehab program was based on a specific path focusing on muscular reinforcement, using mainly the Desmotec D and V.

TREATMENT

During the first phases, Desmotec devices played a very important role in monitoring the patient’s progresses on shifting the load from healthy to operated limb, using D for balance and isometric tests, followed by exercises with specific strap on the V. The last phase of the rehab process was focused on achieving the complete leg extension, complete balance recovery and full load on the limb, using the V for functional movement equipped with a specific tool and isometric works.

Balance test on D -shifting load exercise

Isometric extension at specific knee angle on V

Knee stand rotation exercise on V

Functional sagittal movement on V

Lateral functional movement on V

RESULTS

Desmotec devices allowed the patient to overcome the temporal gap linked to re-conditioning, in full compliance with the physiological time previously estimated. Desmotec therefore allowed to re-evaluate the whole rehab preparatory linked to the functionality of the final gesture.

Hamstrings Tendinopathy

PROBLEM

In the specific case of a patient (runner) affected by insertional left hamstring pain with tendinopathy, the Desmotec devices allowed the introduction of analytical and global exercises since the first stages of the rehab process.

TREATMENT

In the first months, the main goal was to remove any form of pain at rest and during the deambulation phase. Then, some specific exercises focused on contraction along with the isometric phase were introduced, using D and V devices. The patient started a cycle of three training sessions per week, using Desmotec devices and alternating these sessions with running trainings. After the first two weeks, the patient then started a macro-cycle of 24 sessions focused on strength-work, one and two legs squats, using the D device, in order to improve the patient’s strength in the lower limbs, along with mono-articular exercises of pull from prone and standing position, aimed at improving selective strength, using V device.

Effects of in-season enhanced negative work-based vs traditional weight training on change of direction and hamstrings-to-quadriceps ratio in soccer players

Scientific features that investigates the effects of in-season enhanced negative work-based training (ENT) vs weight training in semi-professional soccer players, evaluated and measured through specific tests.

It was published by Dr. Giuseppe Coratella, researcher at the Università degli Studi in Milan, along with Prof. Marco Beato, Desmotec Academy member and Senior Lecturer in Strength & Conditioning at University of Suffolk, on Biol Sport, September 2019.

The study focuses on the different effects of in-season enhanced negative work-based training (ENT) and weight training in the change of direction (COD), sprinting and jumping ability, muscle mass and strength in semi-professional soccer players. The Desmotec device D.Full was also used in the research process.

 

Desmotec D.FULL

 

ABSTRACT

The present study investigated the effects of in-season enhanced negative work-based training (ENT) vs weight training in the change of direction (COD), sprinting and jumping ability, muscle mass and strength in semi-professional soccer players.

Forty male soccer players participated in the eight-week, 1 d/w intervention consisting of 48 squat repetitions for ENT using a flywheel device (inertia=0.11 kg·m-2) or weight training (80%1 RM) as a control group (CON). Agility T-test, 20+20 m shuttle, 10 m and 30 m sprint, squat jump (SJ) and countermovement jump (CMJ), lean mass, quadriceps and hamstrings strength and the hamstrings-to-quadriceps ratio were measured. Time on agility T-test and 20+20 m shuttle decreased in ENT (effect-size =-1.44, 95% CI -2.24/-0.68 and -0.75, -1.09/-0.42 respectively) but not in CON (-0.33, -0.87/0.19 and -0.13, -0.58/0.32). SJ and CMJ height increased in both ENT (0.71, 0.45/0.97 and 0.65, 0.38/0.93) and CON (0.41, 0.23/0.60 and 0.36, 0.12/0.70). Overall, quadriceps and hamstrings strength increased in both ENT and CON (0.38/0.79), but the hamstrings-to-quadriceps ratio increased in ENT (0.31, 0.22/0.40) but not in CON (0.03, -0.18/0.24). Lean mass increased in both ENT (0.41, 0.26/0.57) and CON (0.29, 0.14/0.44). The repeated negative actions performed in ENT may have led to improvements in braking ability, a key point in COD performance. Semi-professional soccer players may benefit from in-season ENT to enhance COD and the negative-specific adaptations in muscle strength and hamstrings-to-quadriceps ratio.
